Description

The present invention relates to an elevator control system and an elevator control method.

BACKGROUND ART When a disaster such as a fire occurs in a building, emergency elevators are provided that can be operated by rescuers such as firefighters. However, in reality, the damage situation on each floor of a building is often unknown. In an environment filled with smoke, it is difficult to see what is going on inside the building, so it is better not to open the car. In addition, backdrafts could occur if elevator doors were opened inadvertently, and firefighting operations were not actually carried out.

Therefore, a technology was being considered to inform rescuers of the disaster situation. For example, Patent Document 1 states, ``During a disaster diagnosis operation, the system stops at each floor and opens and closes the doors, and while the doors are being opened, in order to detect whether or not there is a fire in the landing area, A measurement process that measures the temperature with a temperature sensor installed inside the car, and an image capture process that images the situation inside the car using an in-car camera, and the collected data obtained from the measurement process and image capture process are transferred to the building. The information is transmitted to at least one of the managing center, a display in an emergency elevator, and a mobile terminal owned by a rescue worker heading for disaster relief."

JP 2019-151475 Publication

In the technique disclosed in Patent Document 1, the collected data is transmitted to a mobile terminal, so the rescuer can check the collected data before arriving at the building. It was thought that this would increase opportunities for firefighting operations. However, in a high-rise building, a large amount of collected data for each floor is transmitted to the mobile terminal. In this case, rescuers had to use the small screen of their mobile terminals to search for the floor where the victim was located, or to determine which floors are prohibited from entering, which could hinder rescue operations.

The present invention was made in view of this situation, and an object of the present invention is to provide information necessary for rescue operations.

The elevator control system according to the present invention includes: an elevator control device that controls elevator operation; a monitoring device that remotely monitors elevator operation; a rescuer terminal that acquires information about elevators installed in a building from the monitoring device; and a detection unit that detects detection information necessary for rescue operations at each floor where the car stops, and operates the elevator to monitor the building floor by floor.
The elevator control device includes an operation mode changing section that changes the operation mode of the elevator, and controls the operation of the car according to the operation mode, and when the operation mode is changed to inspection operation mode, it detects each floor where the car has stopped. and an operation control section that determines safety for each floor based on detection information collected from the control section.
The monitoring device includes a monitoring control section that collects the safety judgment results from the elevator control device, and a terminal notification section that notifies the rescuer terminal of the safety judgment results for each floor.
The rescuer terminal is used by the rescuer and displays the safety judgment results notified from the monitoring device.
The detection unit is attached to an autonomously movable robot.
After the robot gets into a moving car in inspection operation mode, when the moving car stops and the door opens, the detection unit detects the state outside the car and sends the detection information to the operation control unit. If a disaster victim is found when the car stops and the door is opened, the victim is urged to get into the car, and the person gets into the car with the victim.
The operation control unit causes the car carrying the disaster victim and the robot to travel to the evacuation floor .

According to the present invention, since the safety judgment result is displayed on the rescuer terminal as information necessary for rescue operations, rescuers can efficiently prepare for rescue operations while checking the rescuer terminal. It can be done in a specific manner. In addition, rescuers can perform firefighting operations while avoiding floors where access is restricted based on the safety judgment results, thereby ensuring the safety of rescuers.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functions or configurations are designated by the same reference numerals and redundant explanations will be omitted.

[First embodiment]
<Example of overall elevator configuration>
FIG. 1 is an overall configuration diagram of an elevator 1.
The elevator 1 includes a car 2 that can be moved up and down inside a hoistway 10. The hoistway 10 is provided with each floor, with the lowest floor being the first floor and the highest floor being the nth floor, as well as a pit that is dug further down from the first floor (lowest floor) of the building. Furthermore, the floor where the fire occurred is assumed to be the k floor.

This elevator 1 can be used by general passengers during normal times, and can be used for firefighting operation in which only rescuers are allowed to ride in an emergency. The elevator 1 includes a car 2, a car device 3, a tail cord 4, a pulley 5, a rope 6, a hoist 7, and a counterweight 8. Inside the hoistway 10, a wire mesh 11 for protecting a switchboard etc. (not shown) and an elevator control device 12 are provided.

The tail cord 4 connects the car 2 and a hoistway 10 through which the car 2 ascends and descends. The tail cord 4 is generally a cord in which a plurality of multicore cables such as control lines and power lines, and a steel cord or the like which is a reinforcing material for supporting the weight of the tail cord 4 are covered with an insulating material. The tail cord 4 has a substantially rectangular cross section to prevent twisting, and is bent to a length that takes into account the traveling range of the car 2 so that a curved portion is always formed.

The car 2 includes a door 2a, a passenger detection sensor 2b, an in-car operation panel 2c, and a switch box 2d. When the passenger car 2 lands on the destination floor registered by the passenger by operating the in-car operation panel 2c, the door 2a and the hall door 13 (see FIG. 2 described later) are opened (hereinafter referred to as "door opening"). ). While the car 2 is running, the door 2a and the hall door 13 are closed (hereinafter referred to as "door closing"). A passenger detection sensor 2b that detects when a passenger gets on and off the vehicle is installed on the door 2a. When a passenger passes through the open door 2a, the passenger detection sensor 2b detects that the passenger is getting on or off the car 2, and sends detection information to the elevator control device 12 through the tail cord 4.

Furthermore, when performing maintenance and inspection of the elevator 1, a switch box 2d provided in the car 2 is opened by a maintenance worker. A maintenance worker can change the operation mode of the elevator 1 from the normal operation mode to the maintenance operation mode through the switch box 2d. In the maintenance operation mode, the car 2 is controlled so as not to run even if a passenger presses the call button 14 on each floor. In the maintenance operation mode, the traveling speed of the car 2 traveling on the hoistway 10 is controlled to be lower than the traveling speed in the normal operation mode.

A car device 3 is attached to the bottom surface of the car 2, and one end of a tail cord 4 is connected thereto. The car device 3 outputs information such as opening/closing information of the door 2a, information on the number or weight of passengers boarding the car 2, etc. to the elevator control device 12 through the tail cord 4.

The other end of the tail cord 4 is connected to an elevator control device 12 installed in the hoistway 10. The elevator control device 12 controls the operation of the elevator 1. Control signals, electric power, etc. for controlling the operation of the car 2 are sent from the elevator control device 12 to the car 2 via the tail cord 4. On the other hand, information such as the destination floor specified by the passenger who has boarded the car 2 and the current floor on which the car 2 is located is sent from the car 2 to the elevator control device 12 via the tail code 4.

Two sets of pulleys 5 are provided on the ceiling of the hoistway 10. A car 2 is attached to one end of the rope 6 via a pulley 5, and a counterweight 8 is attached to the other end of the rope 6 via a hoist 7 installed on the floor within the pit. A counterweight 8 is used to balance the car 2 connected to the rope 6.

A wire mesh 11 is installed on one wall in the hoistway 10 where the elevator control device 12 is installed. In addition to the elevator control device 12 to which the other end of the tail cord 4 is connected, various types of equipment (not shown) are installed between the wire mesh 11 and the wall surface of the hoistway 10. The wire mesh 11 is used to prevent the tail cord 4 swinging in the frontage direction from coming into contact with equipment installed in the hoistway 10 as the car 2 moves up and down.

In the normal operation mode, the hoisting machine 7 winds up the rope 6 under the control of the elevator control device 12, and raises and lowers the car 2 to the destination floor specified by the passenger while adjusting the traveling speed of the car 2. In the maintenance operation mode, the hoisting machine 7 winds up the rope 6 and the car 2 runs under the control of a maintenance worker on the floor.

In this embodiment, a firefighting operation mode is provided for a rescuer such as a firefighter to instruct the operation of the car 2. In the firefighting operation mode, under the control of the elevator control device 12, the car 2 is raised and lowered to the destination floor specified by the rescuer while the door 2a of the car 2 is kept open. Further, in the firefighting operation mode, the car 2 is controlled so as not to run even if the call button 14 on each floor is pressed by a passenger. Further, in the firefighting operation mode, the traveling speed of the car 2 traveling on the hoistway 10 is controlled to be lower than the traveling speed in the normal operation mode and the maintenance operation mode. The detailed contents of the firefighting operation mode will be described later.

Next, various sensors configured in the car 2 will be explained.
FIG. 2 is a diagram showing an example of installation of in-car sensors. FIG. 2 shows the car 2 stopped on the first floor (evacuation floor) as viewed from the frontage direction.

In FIG. 2, it is assumed that the hall door 13 on the first floor and the car door 2a of the car 2 are open. A call button 14 and an emergency call-back operation button 15 are installed in the door pocket of the hall door 13.
In the normal operation mode, when a person in the hall presses the call button 14, the call for the floor on which the call button 14 is installed is registered in the elevator control device 12. The elevator control device 12 causes the car 2 to land on the floor where the call has been registered.

When a fire or the like occurs, the emergency recall operation button 15 is pressed by a building manager or the like. For example, when a person in the hall presses the emergency call-back operation button 15, the elevator control device 12 is notified of the occurrence of a fire. The elevator control device 12 causes the car 2 to go directly to a pre-registered recall floor (usually the first floor), and after landing on the floor, opens the door. In this state, even if the call button 14 is pressed on another floor, the call will not be registered. Then, the elevator control device 12 causes the car 2 to perform an inspection operation. The inspection operation is an operation in which the car 2 is stopped one floor at a time while the car 2 is traveling to the top floor, the door is opened, and the in-car sensor 20 detects the situation on each floor.

The car 2 includes an in-car sensor 20 that detects detection information necessary for rescue operations on each floor where the car 2 stops. The in-car sensor 20 is used as an example of a detection unit installed inside the car 2. The in-car sensor 20 includes sensors such as an in-car camera 21, a temperature sensor 22, and an oxygen concentration sensor 23. The car sensor 20 detects the situation inside the car and outputs detection information to the elevator control device 12 through the tail cord 4 shown in FIG.

The in-car camera 21 is an example of a sensor that outputs an image taken inside the car 2. The in-car camera 21 is capable of photographing the inside of the car 2. The in-car camera 21 is preferably provided at a position where it can photograph the elevator hall when the hall door 13 is opened. The in-car camera 21 outputs image data obtained by photographing the inside of the car 2 as a still image or a moving image as detection information.

The temperature sensor 22 is an example of a sensor that measures the temperature inside the car 2 and outputs temperature information. When the door of the car 2 is opened, the temperature measured by the temperature sensor 22 becomes the temperature of the hall. The temperature sensor 22 outputs the detected temperature as detection information.

The oxygen concentration sensor 23 is an example of a sensor that measures the oxygen concentration within the car 2 and outputs oxygen concentration information. When the door of the car 2 is opened, the oxygen concentration measured by the oxygen concentration sensor 23 becomes the oxygen concentration in the hall. The oxygen concentration sensor 23 outputs the detected oxygen concentration as detection information.

Note that the in-car sensor 20 may include at least one of an in-cage camera 21, a temperature sensor 22, and an oxygen concentration sensor 23. The detection information that the in-car sensor 20 outputs to the elevator control device 12 includes at least one of temperature information, oxygen concentration information, and an image that are output from the in-car sensor 20.

Next, a configuration example of the in-car operation panel 2c will be explained.
FIG. 3 is a diagram showing an example of the external configuration of the in-car operation panel 2c.

The in-car operation panel 2c includes a display panel 31, a firefighting operation operation section 32, a destination floor button 33, and an open/close button 34. A switch box 2d is provided below the in-car operation panel 2c.

On the display panel 31, in addition to the floor number of the landing floor of the car 2, arrows indicating the ascending and descending directions of the car 2, various information to be notified to passengers in the car 2, etc. are displayed. When a fire breaks out in the building, the operation mode is changed to inspection mode automatically or by the building manager, so the words "inspection operation in progress" are displayed on the display panel 31. In addition, the display panel 31 includes information that urges passengers to be careful in order to get passengers off the car 2 quickly, and information that indicates that the destination floor has been changed to an evacuation floor and the car 2 is running. May be displayed.

The firefighting operation operation section 32 is used when switching to the firefighting operation mode and operating the car 2. The firefighting operation operation unit 32 includes a primary firefighting switch 32a, a secondary firefighting switch 32b, and an emergency stop switch 32c. Furthermore, in the firefighting operation mode, primary firefighting operation or secondary firefighting operation is possible. When a rescuer inserts a key into the primary firefighting switch 32a and turns it on, the mode switches to primary firefighting operation. In the primary firefighting operation, after the rescuer presses the destination floor button 33 and the door 2a is closed, the car 2 travels at the rated speed to the destination floor. Then, the car 2 lands on the destination floor, and when the rescuer presses the door open button, the door opens.

If the primary firefighting switch 32a is turned on, the rescuer can turn on the secondary firefighting switch 32b by inserting a key into the secondary firefighting switch 32b, thereby switching to secondary firefighting operation. However, in order to turn on the secondary fire-fighting switch 32b, the rescuer must keep the key of the primary fire-fighting switch 32a turned on. In the secondary firefighting operation, if the rescuer simultaneously presses the secondary firefighting switch 32b and the destination floor button 33 for several seconds, the car 2 will depart even if the door 2a is not closed. When the rescuer releases the key of the secondary firefighting switch 32b while the car 2 is running in the secondary firefighting operation, the secondary firefighting switch 32b is automatically turned off and the car 2 stops. In addition, if it is necessary to make an emergency stop during the secondary firefighting operation, the emergency stop switch 32c is used. When the rescuer presses the emergency stop switch 32c, the running car 2 comes to an emergency stop.

The destination floor button 33 allows the passenger to select and register a desired destination floor. In FIG. 3, only the destination floor buttons 33 for the first, k, and n floors shown in FIG. 1 are shown.
The open/close button 34 is a button for instructing opening/closing of the door 2a. In conjunction with the opening and closing of the door 2a, the hall door 13 (see FIG. 2) of the floor on which the car 2 has landed is also opened and closed.

Next, a configuration example of an elevator control system for remotely monitoring the elevator 1 will be described.
FIG. 4 is a block diagram showing a configuration example of the elevator control system 100.

The elevator control system 100 has a function of monitoring the damage situation of the building for each floor by operating the elevator 1 that is operated in the building where the disaster has occurred. This elevator control system 100 includes an elevator control device 12, an in-car sensor 20, a monitoring device 50, and a rescuer terminal 60. The elevator control device 12 and the monitoring device 50 can communicate via a network N such as the Internet. Furthermore, the monitoring device 50 can provide various information to the rescuer terminal 60 via the network N.

As described above, the detection information indicating the situation inside the car 2 detected by the in-car sensor 20 is input to the elevator control device 12.

The elevator control device 12 includes an operation mode change section 41, a detection information storage section 42, an operation control section 43, and a notification section 44.
The driving mode changing unit 41 changes the driving mode of the car 2 to any one of a normal driving mode, a maintenance driving mode, and a firefighting driving mode. Information on the driving mode switched by the driving mode changing section 41 is output to the driving control section 43.

The detection information storage unit 42 stores detection information and safety determination results. The safety determination result is, for example, information such as which floor is abnormal and entry of rescuers is restricted when a fire breaks out in the building. Details of the detection information stored in the detection information storage section 42 will be explained later with reference to FIG. 5.

The operation control section 43 controls the operation of the car 2 according to the operation mode changed by the operation mode change section 41. In addition, when the operation mode is changed to the inspection operation mode when a disaster occurs, the operation control unit 43 performs safety control on a floor-by-floor basis based on the detection information collected from the in-car sensors 20 on each floor where the car 2 has stopped. to judge. Here, the operation control unit 43 writes the detection information and the safety judgment result of determining that a floor where the detection information deviates from the prescribed normal information as abnormal, into the detection information storage unit 42, and writes the detection information to the detection information storage unit 42. The detection information stored in the section 42 is updated. Further, the operation control unit 43 transmits the safety determination result and detection information read from the detection information storage unit 42 to the monitoring device 50. Further, the operation control unit 43 instructs the notification unit 44 to notify information including the occurrence of a fire in the building and an abnormality in the elevator 1.

The notification unit 44 reports information including the occurrence of a fire in the building and an abnormality in the elevator 1 based on instructions from the operation control unit 43. This information is displayed, for example, on the display panel 31 inside the car 2, and informs passengers of the building situation or informs rescuers that the car 2 is in operation for inspection or firefighting. . The notification unit 44 may be a speaker provided in the car 2 or in the building, which notifies information by voice or emits an alarm. Further, the notification unit 44 may be a red light that visually reports the occurrence of an abnormality.

The monitoring device 50 remotely monitors the operation of the elevator 1. For this reason, the monitoring device 50 is provided, for example, in a monitoring center (not shown) that can monitor the status of a plurality of elevator control devices 12. An operator at the monitoring center monitors the operating status of the elevator 1 in each building based on information provided from the monitoring device 50.

The monitoring device 50 includes a monitoring control section 51, a display section 52, an input section 53, a terminal notification section 54, and an information storage section 55.
The monitoring control unit 51 collects operation information and safety judgment results of the elevator 1 from the elevator control device 12 . As described above, the monitoring device 50 can collect operation information of the car 2 from a plurality of elevator control devices 12. Therefore, when the supervisory control unit 51 receives a notification of the start of inspection operation from the elevator control device 12 installed in the building where the fire occurred, it instructs the elevator control device 12 to transmit the safety determination result. Then, the monitoring control unit 51 receives the safety determination result from the elevator control device 12. The monitoring control unit 51 can also collect detection information for each floor in addition to the safety judgment results from the elevator control device 12.

The display section 52 and the input section 53 are configured as, for example, a monitoring terminal provided at a monitoring center. The display unit 52 displays the operating status of each elevator 1. The operator can instruct the output of the detection information collected from the elevator control device 12 to the rescuer terminal 60 through the input unit 53. The contents instructed from the input section 53 are input to the monitoring control section 51. Then, the monitoring control unit 51 instructs the terminal notification unit 54 to output the detection information.

The terminal notification unit 54 notifies the rescuer terminal 60 of the safety determination result for each floor. At this time, the terminal notification unit 54 may notify the rescuer terminal 60 of detection information for each floor in addition to the safety determination result based on instructions from the supervisory control unit 51.
The information storage unit 55 stores operation information, detection information, etc. for each elevator 1 received from each elevator control device 12.

The rescuer terminal 60 is a terminal owned and used by a rescuer, and is capable of acquiring the safety judgment result of the elevator 1 installed in the building from the monitoring device 50. Note that the rescuer terminal 60 may be installed inside a fire engine or the like where a rescuer waits. The safety determination result notified from the monitoring device 50 is displayed on the display unit (not shown) of the rescuer terminal 60. The display section of the rescuer terminal 60 displays the address of the building where the fire occurred, information on the elevator 1 that can be operated in firefighting mode, detection information collected on the floor where the safety judgment was made, etc. may be displayed. The rescuer can confirm the display content of the rescuer terminal 60, understand the floor of the elevator 1 where the fire originated, the presence or absence of abnormality on each floor, and perform rescue operations safely.

Next, the contents of the detection information storage section 42 will be explained.
FIG. 5 is a table configuration diagram showing an example of detection information stored in the detection information storage section 42. As shown in FIG.

The detection information is configured as a table having fields for floor, temperature, oxygen concentration, image, and abnormality flag.
The floor field stores the number of all floors on which the car 2 can run in the building.
In the temperature field, the temperature measured by the temperature sensor 22 is stored for each floor. Here, the prescribed normal information regarding the temperature is, for example, "25°C". If the temperature deviates from 25°C by 10°C or more, it is determined that there is an abnormality.
In the oxygen concentration field, the oxygen concentration measured by the oxygen concentration sensor 23 is stored for each floor. Here, the prescribed normal information regarding the oxygen concentration is, for example, "21%". If the oxygen concentration deviates from 20% by 3% or more, it is determined that there is an abnormality.

The image field stores information about the presence or absence of an abnormality at the photographing location, which is determined by the operation control unit 43 by analyzing the image photographed by the in-car camera 21. If there is no abnormality on the floor, "No abnormality" is stored because there is no smoke etc., and if there is an abnormality such as smoke filling the floor, "Full of smoke" is stored as the abnormality content. be done. Note that for "no abnormality" and the content of the abnormality, pre-classified codes may be stored in the image field. Alternatively, the captured image itself may be stored in the image field.

The abnormality flag field stores an abnormality flag indicating the presence or absence of an abnormality determined by the operation control unit 43 for each floor. For floors where the operation control unit 43 determines that there is no abnormality, the abnormality flag is turned OFF. On the other hand, on a floor where the operation control unit 43 determines that some kind of abnormality has occurred, the abnormality flag is turned ON.

In this way, the operation control unit 43 determines whether the k floor is the source floor of the fire or an abnormality based on the detection information of the k floor where the temperature is 50°C, the oxygen concentration is 15%, the image is "full of smoke", and the abnormality flag is ON. It is determined that this is the floor where the problem occurred. Therefore, the rescuer terminal 60 may be provided with only the detection information of the floors whose abnormality flags are set to ON. Note that time information at the time when the in-car sensor 20 detects on each floor may be added to the detection information. Therefore, the rescuer can determine how much time has elapsed since the time when the person entered the building was detected in the past.

Next, the hardware configuration of the computer 70 that constitutes each device of the elevator control system 100 will be explained.
FIG. 6 is a block diagram showing an example of the hardware configuration of the computer 70. The computer 70 is an example of hardware used as a computer that can operate as the elevator control device 12 or the monitoring device 50.

The computer 70 includes a CPU (Central Processing Unit) 71, a ROM (Read Only Memory) 72, a RAM (Random Access Memory) 73, a nonvolatile storage 75, and a network interface 76, each connected to a bus 74.

The CPU 71 reads software program codes that implement each function according to the present embodiment from the ROM 72, loads them into the RAM 73, and executes them. Variables, parameters, etc. generated during the arithmetic processing of the CPU 71 are temporarily written in the RAM 73, and these variables, parameters, etc. are read out by the CPU 71 as appropriate. However, instead of the CPU 71, an MPU (Micro Processing Unit) may be used. The CPU 71 included in the elevator control device 12 realizes the functions of the operation mode changing section 41 and the operation control section 43. Further, the functions of the monitoring control section 51 and the terminal notification section 54 are realized by the CPU 71 configured in the monitoring device 50.

As the non-volatile storage 75, for example, a HDD (Hard Disk Drive), an SSD (Solid State Drive), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, or a non-volatile memory can be used. It will be done. In this non-volatile storage 75, in addition to an OS (Operating System) and various parameters, programs for operating the computer 70 are recorded. The ROM 72 and the non-volatile storage 75 record programs, data, etc. necessary for the operation of the CPU 71, and serve as an example of a computer-readable non-transitory recording medium that stores programs to be executed by the computer 70. used. For example, the detection information storage unit 42 of the elevator control device 12 and the information storage unit 55 of the monitoring device 50 are configured in a nonvolatile storage 75.

For example, a NIC (Network Interface Card) is used as the network interface 76, and various data can be sent and received between devices via a LAN (Local Area Network) connected to a terminal of the NIC, a dedicated line, etc. It is possible. The elevator control device 12 is provided with a network interface 76 through which detection information is input from the in-car sensor 20 and detection information and determination results are transmitted from the operation control section 43 to the monitoring device 50. The monitoring device 50 is also provided with a network interface 76 that receives detection information and judgment results from the elevator control device 12 and transmits the detection information and judgment results from the terminal notification section 54 to the rescuer terminal 60.

Next, the control processing of the elevator control device 12 will be explained.
FIG. 7 is a flowchart illustrating an example of a process in which the elevator control device 12 controls the operation of the car 2. It is assumed that rescuers have not arrived at the building at the start of this process.

First, when a fire occurs in a building, the elevator control device 12 is notified of the occurrence of a fire (S1). When the occurrence of a fire is notified, the operation mode change unit 41 changes the operation mode from the normal operation mode or the maintenance operation mode to the inspection operation mode. The operation control unit 43 starts an inspection operation to check the situation on each floor (S2).

When the operation mode is changed to the inspection operation mode, the operation control unit 43 registers the floor one floor above the floor on which the car 2 has landed as the destination floor, causes the car 2 to travel, and returns the car to the inspection operation mode. The process of opening the car 2 and collecting detection information is repeated until the car 2 reaches a predetermined upper floor (for example, the top floor). Therefore, the operation control unit 43 that started the inspection operation automatically registers the floor one floor above the floor where the car 2 is currently stopped as the destination floor, and causes the car 2 to travel (S3). . Then, after the car 2 lands on the registered destination floor, the operation control unit 43 opens the door of the car 2 (S4).

Next, the operation control unit 43 compares the detection information (temperature, oxygen concentration, and image) input from the in-car sensor 20 with prescribed normal information, and performs a safety check on the floor on which the car 2 has landed. (S5). If the operation control unit 43 determines that the floor on which the car 2 has landed is safe, it leaves the abnormality flag of the detection information stored in the detection information storage unit 42 OFF. On the other hand, when the operation control unit 43 determines that the floor on which the car 2 has landed is unsafe, that is, there is an abnormality, the operation control unit 43 sets the abnormality flag by changing the abnormality flag to ON.

After that, the operation control unit 43 closes the door of the car 2 (S6). Next, the operation control unit 43 determines whether the floor on which the car 2 has landed is the top floor (S7). If the floor on which the user has landed is not the top floor (NO in S7), the operation control unit 43 repeats the processes of steps S3 to S7 until the floor on which the user has landed is the top floor.

Then, after the car 2 reaches the upper limit floor (top floor), the operation control unit 43 causes the car 2 to travel to the evacuation floor, and sends information on the floor determined to be less safe from the terminal notification unit 54. The rescuer terminal 60 is notified. In other words, if the floor on which the car 2 has landed is the top floor (YES in S7), the operation control unit 43 registers the evacuation floor (usually the first floor) as the destination floor of the car 2, and 2 to the evacuation floor (S8). Thereafter, car 2 arrives at the evacuation floor (S9). The operation control unit 43 then transmits the detection information read from the detection information storage unit 42 to the monitoring control unit 51 of the monitoring device 50.

Then, as a result of the safety confirmation of each floor, the operation control unit 43 determines whether there is a floor where entry is restricted (hereinafter referred to as a "dangerous floor") based on the received detection information (S10). If there is a dangerous floor (YES in S10), the operation control unit 43 causes the notification unit 44 to notify the dangerous floor. The notification unit 44 notifies the monitoring device 50, a display panel installed in the hall, etc. of a dangerous floor (S11).

In addition, after the car 2 reaches the upper limit floor (top floor), the operation control unit 43 causes the car 2 to travel to the evacuation floor and stops the car 2 on a floor determined to be unsafe. Control to prohibit (prohibit service) can also be performed. Due to this control, even if the car 2 is operated by a firefighter, it will not stop at a floor determined to be unsafe.

When there is no dangerous floor (NO in S10), or after a dangerous floor is notified in step S11, when a rescuer arrives at the building, a firefighting operation is carried out (S12). For this reason, the operation mode change unit 41 accepts a change to the firefighting operation mode by the rescuer after the rescuer terminal 60 is notified of the information on the floor determined to be less safe. As described above, the rescuer can carry out a firefighting operation using the primary firefighting switch 32a and the secondary firefighting switch 32b.

In the elevator control system 100 according to the first embodiment described above, when a disaster such as a fire occurs, the elevator 1 is monitored in order to confirm the safety of each floor before rescuers arrive. For this reason, when the door opens after the car 2 has landed on the floor, the situation inside the car 2 is checked by the in-car sensor 20, and the rescuer is informed of the situation. It can be judged on a case-by-case basis.

Here, during the inspection operation, the elevator control system 100 moves the car 2 one floor at a time to the top floor, opens the door at each floor, and controls the operation control unit 43 based on the detection information detected by the in-car sensor 20. Conduct safety checks of halls on each floor. After that, the operation control unit 43 drives the car 2 to the evacuation floor, and then notifies people in the building of the dangerous floor through the notification unit 44. Therefore, the building manager and the like can quickly identify dangerous floors of the building.

Furthermore, the monitoring control unit 51 of the monitoring device 50 also notifies the rescuer terminal 60 of dangerous floors through the terminal notification unit 54. The information notified to the rescuer terminal 60 in this way is the result of the safety judgment made in advance by the operation control unit 43. Therefore, rescuers check the rescuer terminal 60 and understand which floors are safe or dangerous without having to judge the safety of each floor themselves, carry out firefighting operations, and carry out rescue operations. Can carry out activities.

Note that the processing in steps S10 and S11 in FIG. 7 may be performed by the monitoring device 50. In this case, the monitoring control unit 51 of the monitoring device 50 receives the detection information from the operation control unit 43 after the process of step S9. Then, the monitoring control unit 51 checks each floor for safety based on the received detection information, and determines whether there is a dangerous floor (S10). If there is a dangerous floor (YES in S10), the monitoring control unit 51 outputs information indicating the dangerous floor to the terminal notification unit 54. The terminal notification unit 54 notifies the rescuer terminal 60 of this information via the network N. Since dangerous floors are displayed on the rescuer terminal 60, the rescuer can safely perform rescue operations.

[Second embodiment]
Next, an elevator control system according to a second embodiment of the present invention will be described. In this embodiment, a robot capable of autonomous movement performs safety checks on each floor.
FIG. 8 is an overall configuration diagram of the elevator 1. The situation of the building in which the elevator 1 is installed is similar to the building shown in FIG. However, it is assumed that the robot 80 is waiting on the first floor of the building.

The robot 80 can move autonomously. Usually, the robot 80 is used as a guide robot to guide people visiting the building. When an abnormality such as a fire occurs in the building, the robot 80 moves autonomously, gets on the car 2, and moves together with the car 2 during inspection operation. The robot 80 receives detection information indicating that the robot sensor 90 detects the outside of the car 2 when the car 2 moves in the inspection operation mode and then stops and opens the door. It is possible to transmit it to the operation control section 43. Moreover, the robot 80 gets off the car 2 at the floor where the car 2 stopped, and after patrolling the floor, gets on the car 2 again. Then, it is possible to notify the elevator control device 12 of the detailed situation (for example, detection information) of each floor.

Next, various sensors configured in the robot 80 will be explained.
FIG. 9 is a diagram showing the inside of the car 2 and a configuration example of the robot 80. FIG. 9 shows the car 2 stopped on the first floor (evacuation floor) as viewed from the frontage direction.

The robot 80 includes a robot sensor 90 as an example of a detection unit that detects detection information necessary for rescue operations for each floor on which the car 2 travels. The robot sensor 90 includes a robot camera 81 , a temperature sensor 82 , an oxygen concentration sensor 83 , a human sensor 84 , and a wireless communication section 85 . The robot 80 is used as a sensor capable of detecting the conditions of the car 2 and the hall and outputting detected information to the elevator control device 12.

The robot camera 81 is, for example, an example of a sensor that is attached to the head of the robot 80 and outputs an image taken at a location where the robot 80 has moved. What is indicated by a broken line in the figure is the photographing range of the robot camera 81. Further, the robot 80 can move anywhere on the floor by rotating wheels driven by an internal motor or the like. Therefore, the image taken by the robot camera 81 includes information indicating not only the inside of the car 2 and the hall, but also the location where the robot 80 can move on the floor where the car 2 has landed.

The temperature sensor 82 is an example of a sensor that measures the temperature of a place where the robot 80 has moved and outputs temperature information. Therefore, the temperature sensor 82 can detect the temperature inside the car 2 and the temperature at the location where the robot 80 has moved. The temperature sensor 82 outputs the detected temperature as detection information.

The oxygen concentration sensor 83 is an example of a sensor that measures the oxygen concentration at a location where the robot 80 has moved and outputs oxygen concentration information. Therefore, the oxygen concentration sensor 83 can detect the oxygen concentration inside the car 2 and the oxygen concentration at the location where the robot 80 has moved. The oxygen concentration sensor 83 outputs the detected oxygen concentration as detection information.

The human sensor 84 is an example of a sensor that detects infrared rays or the like emitted by a disaster victim in a place where the robot 80 has moved, and outputs human detection information. The human sensor 84 outputs human detection information as detection information.
The wireless communication unit 85 is capable of wireless communication with the wireless communication unit 24 provided inside the car 2. The robot 80 wirelessly transmits detection information through the wireless communication unit 85.

Note that the robot sensor 90 may include at least one of a robot camera 81, a temperature sensor 82, an oxygen concentration sensor 83, and a human sensor 84. The detection information output by the robot 80 to the elevator control device 12 includes at least one of temperature information, oxygen concentration information, image, and human detection information output from the robot sensor 90.

The image taken by the robot camera 81 may include people on the floor. If the person can move on his own, the robot 80 instructs the person to get into the car 2 and escape together to the evacuation floor. However, if the person is unable to move on his or her own, a rescuer is required to rescue the person, so the robot 80 notifies the elevator control device 12 of the presence of the person who is unable to move on his or her own.

The car 2 is provided with an in-car operation panel 2c, a switch box 2d, an in-car camera 21, and a wireless communication section 24.
The in-car operation panel 2c, the switch box 2d, and the in-car camera 21 are the same as those described in the first embodiment. The display panel 31 (see FIG. 3) of the in-car operation panel 2c displays the number of disaster victims remaining on each floor, as well as the floor where it has been determined that there is an abnormality.

The wireless communication unit 24 wirelessly communicates with the robot 80 riding in the cage 2. Then, the wireless communication unit 24 outputs the detection information received from the robot 80 to the elevator control device 12. Furthermore, the wireless communication unit 24 can transmit information about movable locations on each floor to the robot 80. The robot 80 can move from floor to floor based on information about movable locations received from the wireless communication unit 24 . Note that the wireless communication unit 24 may be provided not only within the car 2 but also within the floor.

Note that the car 2 may be provided with the temperature sensor 22 and the oxygen concentration sensor 23 according to the first embodiment, and together with the in-car camera 21, the in-car sensor 20 may be configured.

Next, a configuration example of an elevator control system for remotely monitoring the elevator 1 will be described.
FIG. 10 is a block diagram showing a configuration example of the elevator control system 100A. Elevator control system 100A has substantially the same configuration as elevator control system 100 according to the first embodiment. However, the elevator control system 100A includes a robot 80 and a wireless communication unit 24.

Further, the elevator control device 12 includes a detection information storage section 42A in addition to the operation mode change section 41, operation control section 43, and notification section 44 according to the first embodiment. Therefore, the contents of the detection information storage section 42A will be explained with reference to FIG. 11.

FIG. 11 is a table configuration diagram showing an example of detection information stored in the detection information storage unit 42A.

The detection information is configured as a table having fields of floor, temperature, oxygen concentration, image, number of remaining disaster victims, and abnormality flag. The floor, temperature, oxygen concentration, image, and abnormality flag have the same contents as each field of the detection information according to the first embodiment.

The number of remaining disaster victims field stores the number of disaster victims who have not yet evacuated on each floor as the number of remaining disaster victims. For example, assume that the k floor, which is the floor where the fire originated, is filled with smoke, so two remaining disaster victims appear in the image. Therefore, the number of remaining disaster victims counted from the image taken on the k floor is stored as, for example, "2". Additionally, if a disaster victim fails to evacuate even on the m floor above the k floor, the number of remaining disaster victims counted from the image taken on the m floor is stored as "1", for example. .

The abnormality flag of the floor where the image on which it is determined that an abnormality has occurred is taken is set to ON. Furthermore, the abnormality flag is also set to ON for the floor where the remaining disaster victim was found. Therefore, the rescuer can go to the floor where the abnormality flag has been turned on and make a decision to give priority to rescuing the remaining disaster victims.

Next, control processing of the elevator control device 12 according to the second embodiment will be explained.
12 and 13 are flowcharts showing an example of a process in which the elevator control device 12 controls the operation of the car 2.

First, when a fire occurs in the building, the elevator control device 12 is notified of the occurrence of the fire (S21). The elevator control device 12 transmits an inspection operation instruction to the robot 80 via the wireless communication unit 24. The robot 80 moves to the elevator hall on the first floor (evacuation floor) (S22).

When the car 2 arrives at the first floor, the robot 80 waits until the passengers get off the car 2. Then, when all passengers get off the car 2, the robot 80 gets on the car 2 (S23). As shown in steps S3 and S4 in FIG. 7, in the inspection operation, the operation control unit 43 registers the next higher floor as the destination floor, and after the door is closed, the car 2 runs (S24). After landing on the upper floor, the door is opened (S25).

Next, the robot 80 performs a safety check inside the hall while riding in the car 2. Safety confirmation at this time is performed by each sensor of the robot 80 collecting the temperature, oxygen concentration, and images in the hall. The temperature, oxygen concentration, and images collected by each sensor of the robot 80 are output to the operation control unit 43 via the wireless communication unit 24.

The operation control unit 43 performs safety confirmation based on information such as temperature, oxygen concentration, and images input from the wireless communication unit 24. When the operation control unit 43 determines that the floor on which the car 2 has landed is unsafe, that is, there is an abnormality, it sets an abnormality flag by changing the abnormality flag to ON (S26).

Further, the operation control unit 43 determines whether or not there is a disaster victim in the hall (S27). The presence or absence of a disaster victim is determined, for example, by the operation control unit 43 based on the person detection information collected from the robot 80. If there is a disaster victim in the hall (S27: YES), it is necessary to evacuate this disaster victim as soon as possible. Therefore, the process moves to step S30 in FIG. 13 where the connector A is connected. In this process, when the robot 80 discovers a disaster victim when the car 2 stops and the door opens, the robot 80 urges the victim to get into the car 2 and rides in the car 2 with the victim. Then, the operation control unit 43 causes the car 2 carrying the disaster victim and the robot 80 to travel to the evacuation floor (S30).

On the other hand, if there is no disaster victim in the hall (NO in S27), the operation control unit 43 closes the door of the car 2 (S28). Next, the operation control unit 43 determines whether the floor on which the passenger landed is the top floor (S29). If the floor on which the user has landed is not the top floor (NO in S29), the operation control unit 43 repeats the processes of steps S24 to S29 until the floor on which the user has landed is the top floor.

On the other hand, if the floor on which the car 2 has landed is the top floor (YES in S29), the process moves to step S31 in FIG. . The robot 80 gets off the floor on which the car 2 has landed, moves within the floor, and checks whether there is a disaster victim on the floor (S31).

Next, the robot 80 determines whether there is a disaster victim on the floor (S32). If there are no disaster victims (NO in S32), the robot 80 returns to the hall and gets into the car 2 (S34). The robot 80 that has returned to the car 2 outputs the temperature, oxygen concentration, and image of the floor where the remaining disaster victim is determined to be present to the operation control unit 43 via the wireless communication unit 24.

On the other hand, if there is a disaster victim (YES in S32), the robot 80 determines whether the disaster victim is able to move (S33). This determination may be made such that, for example, when a disaster victim presses a button or the like displayed on a touch panel of the robot 80, the robot 80 determines that the disaster victim is able to move.

If the disaster victim is able to move (YES in S33), the process moves to step S30, where the robot 80 and the disaster victim both board the car 2 and evacuate to the evacuation floor. At this time, the robot 80 notifies the operation control unit 43 that the robot 80 has boarded the car 2 together with the disaster victim. Then, the operation control unit 43 registers the evacuation floor as the destination floor and causes the car 2 to travel.

On the other hand, if the robot 80 determines that the disaster victim cannot move (NO in S33), the robot 80 returns to the hall and gets into the car 2 (S34). Then, the robot 80 transmits to the operation control unit 43 the floor and location where the disaster victim who cannot move is left.

Next, the operation control unit 43 determines whether the floor on which the car 2 is currently landing is the lowest floor (S35). If the floor on which the car 2 has landed is not the lowest floor (first floor) (NO in S35), the operation control unit 43 automatically moves the car 2 to the floor one floor below the floor where it is currently stopped. It is registered as the destination floor, the car 2 is driven after closing the door (S36), and the process returns to step S31 to open the door of the car 2.

In this manner, the operation control unit 43 repeats the processes of steps S31 to S36 after the car 2 reaches the upper limit floor until the car 2 reaches the evacuation floor. In this process, the robot 80 searches for victims by moving from floor to floor for each floor where the car 2 has stopped and the door has been opened.

On the other hand, if the floor on which the robot has landed is the lowest floor (YES in S35), the operation control unit 43 determines whether there are any remaining disaster victims collected from the robot 80 as a result of the safety confirmation. At this time, the operation control unit 43 writes in the detection information storage unit 42 the floor where the disabled victim is left as the rescue priority floor. Then, the operation control unit 43 transmits the safety determination result of each floor and the rescue priority floor to the monitoring device 50. At this time, the operation control unit 43 may transmit the detection information collected on each floor to the monitoring device 50.

The monitoring control unit 51 of the monitoring device 50 determines whether there are any remaining disaster victims on the rescue priority floor based on the rescue priority floor and the number of remaining disaster victims received from the elevator control device 12 (S37). When the supervisory control unit 51 determines that there are remaining disaster victims (YES in S37), it notifies the rescuer terminal 60 that the floor where the remaining disaster victims are located is the rescue priority floor (S38).

After notifying the rescuer terminal 60 in step S38 or after the robot 80 determines that there are no disaster victims remaining (NO in S37), the operation control unit 43 controls the temperature, oxygen concentration, and Conduct safety checks based on information such as images. Then, as a result of the safety check, the operation control unit 43 determines whether there is a floor that is dangerous to enter, based on the detection information read from the detection information storage unit 42A (S39).

If there is a dangerous floor (YES in S39), the operation control unit 43 sets the abnormality flag by setting the abnormality flag to ON, and disables the service so that the car 2 does not stop on the floor determined to be dangerous. Permission is granted (S40). Further, the operation control unit 43 transmits the safety determination result to the monitoring device 50. The monitoring control unit 51 of the monitoring device 50 notifies the rescuer terminal 60 of the safety determination result through the terminal notification unit 54.

When there is no dangerous floor (NO in S39), or after the service on the dangerous floor is disallowed in step S40, when a rescuer arrives at the building, a firefighting operation is carried out (S41). As described above, the rescuer can carry out a firefighting operation using the primary firefighting switch 32a and the secondary firefighting switch 32b.

The elevator control system 100A according to the second embodiment described above uses the robot 80 to monitor the elevator 1 in order to confirm the safety of each floor before rescuers arrive in the event of a fire. Therefore, when the door of the car 2 is opened after landing on the floor, the robot 80 confirms the situation inside the car 2 and notifies the rescuer, thereby making it possible to determine whether it is possible to get out of the car during firefighting operation.

Then, each time the robot 80 gets on the car 2 and the car 2 lands on each floor, the robot 80 detects the situation around the hall and transmits it as detection information. Therefore, the situation around the hall can be safely grasped through the robot 80. The inspection operation performed before the rescuers arrive at the building allows the rescuers to know the safety judgment results for each floor, allowing them to perform firefighting operations safely. Furthermore, if there are disaster victims around the hall, the robot 80 urges the victims to board the car 2, and then the victim can be quickly taken down to the evacuation floor.

Furthermore, by using the robot 80 instead of the in-car sensor 20, the elevator control device 12 can monitor the situation on each floor without adding unnecessary equipment (various sensors, cameras, etc.) inside the car or in the hall. can be grasped. Therefore, the cost for configuring the elevator control system 100A can be reduced.

Moreover, when the in-car sensor 20 attached to the car 2 is malfunctioning, the car 2 must be stopped. However, if the robot sensor 90 attached to the robot 80 is malfunctioning, it is possible to take measures such as repairing only the robot 80, so that passengers using the elevator 1 are not inconvenienced.

Further, if there are no disaster victims around the hall, the car 2 moves from the top floor to the lower floors in order, and the robot 80 gets off at each floor and moves within the floor. The robot 80 then detects the presence or absence of any disaster victims who remain on the floor from which the robot 80 alighted. The floor where the remaining disaster victim was located is notified to the monitoring device 50 as a rescue priority floor, and the rescuer terminal 60 is also notified of the rescue priority floor, so that the rescuer can perform the rescue as soon as possible. Therefore, even if the robot 80 is unable to transport the remaining disaster victims, it is possible to speed up the rescue of the remaining disaster victims.

Furthermore, as a result of the safety confirmation performed by the robot 80, the condition of the remaining disaster victims is displayed on the rescuer terminal 60. Therefore, the rescuer can check the condition of the remaining disaster victim before going to the floor where the remaining disaster victim is located, making it easier to make advance preparations such as gathering the necessary equipment to rescue the remaining disaster victim.

Note that in the second embodiment, since the robot 80 is movable within the floor, the temperature and oxygen concentration may change locally. For this reason, codes such as area numbers assigned to each location are added to records for each floor, indicating where the temperature or oxygen concentration is high, or where the remaining disaster victims are. Good too. The detection information may also include a code as well as information for each floor. By checking the detection information through the rescuer terminal 60, the rescuer can head to the rescue after knowing which location is highly safe and how many disaster victims are in each area.

Further, in step S40 of FIG. 13, if the operation control unit 43 determines that the floor does not require inspection if there are no remaining disaster victims, the terminal notification unit 54 sends the rescuer terminal 60 to the floor that does not require inspection. may be notified. By knowing in advance which floors do not require inspection, rescuers can carry out rescue operations without having to allocate unnecessary personnel to those floors.

[Modified example]
In addition, in each embodiment mentioned above, after the operation control part 43 wrote the detection information into the detection information storage part 42, the detection information was transmitted to the monitoring device 50 at a predetermined timing. However, the detection information may be transmitted to the monitoring device 50 at the timing when the in-car sensor 20 according to the first embodiment detects the detection information. Further, the detection information detected by the robot sensor 90 of the robot 80 according to the second embodiment is the timing when the robot 80 gets on the car 2 or the timing when the car 2 stops at the top floor or the bottom floor. It may also be transmitted to the monitoring device 50.

Furthermore, the disaster that occurs in the building in each of the embodiments described above is not limited to fire. For example, the elevator control system 100, 100A may monitor the damage situation of the building for each floor by the elevator 1 even in case of an earthquake, electric leakage, or water disaster, and send the safety judgment result to the rescuer terminal 60.

Further, the elevator 1 according to each of the embodiments described above can be used by general passengers during normal times. However, the building may be provided with a separate elevator that can be ridden by ordinary passengers, and the elevator 1 may be used as an emergency elevator that cannot be ridden by ordinary passengers even in normal times.
