Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention is useful for workers engaged in various works such as patrolling and spotting inside specific buildings such as underground substations, buildings, underground malls, and tunnels. On the other hand, this invention relates to a disaster prevention monitoring and guidance system that can provide accurate instructions and guidance when placing a disaster order.

(Prior art) When a disaster such as a fire occurs inside a building, conventional evacuation guidance systems mainly rely on guide rings and speakers that indicate the location of emergency exits and evacuation stairs, making it difficult to provide reliable evacuation guidance. It is. Therefore, in order to solve this problem, contact switches are placed in a grid pattern on the floor of buildings such as department stores where there are a large number of people, and evacuation guidance is provided according to the distribution of people in each section. A system for performing this has been proposed in Japanese Patent Application Laid-Open No. 51-98199.

(Problem to be solved by the invention) However, such a system requires a large number of contact switches to be installed all over the floor, and the contacts do not have a long service life due to wear and tear, making it difficult to install them in existing buildings. However, there are disadvantages that cause many difficulties in construction. In addition, security systems that install sensors near building entrances and exits to detect intruders have been applied to buildings in recent years, but they cannot monitor the location of personnel inside the building.
For example, when a fire occurs, there are problems such as not only being unable to provide accurate evacuation guidance, but also being unable to activate the disaster prevention shutters to extinguish the fire (Measures to solve the problem) The present invention was completed in order to solve these conventional problems, and it divides the inside of a building into a plurality of receiving areas and installs an infrared receiving element for detecting infrared rays generated from the human body in each receiving area. In addition, the control room is equipped with a position determination device that determines the current position of each worker based on signals from receivers placed in each reception area inside the building, and a position determination device that determines the current position of each worker. This system is characterized by being equipped with a screen display device that displays the position and a voice transmitting device that gives commands and guidance to the worker.

(Embodiment) Next, the present invention will be explained in detail with reference to the illustrated embodiment. In the figure, the right side divided by two dotted diagonal lines is the control room (2) where the monitor is stationed, and the left side is the object to be monitored. The interior of the building (1) is shown. The interior of the building (1) is divided into multiple receiving areas (3), and each receiving area (3) is equipped with an infrared receiving element that detects infrared rays with a wavelength of 5 to 20 μm generated from the human body of the worker (30). A receiver (4) is installed. The receiver (4) is installed on the ceiling or wall inside the building, and can reliably receive infrared radiation generated from the worker's body no matter where the worker is inside the building. They are also installed indoors, in hallways, on stairs, etc. The number of installed units depends on the spread angle of infrared rays,
The determination should be made taking into consideration the obstacles and the installation height of the receiver (4), but the more installed, the more accurate the worker's position confirmation will be. In addition, the required reception area inside the building (3)
There are various types of disaster prevention equipment such as differential type, compensation type, or constant temperature type heat detectors that detect the heat caused by fire, ionization type and photoelectric type smoke detectors that detect smoke, and ceramic type oxygen sensors that detect oxygen concentration. A detection sensor (5) is installed. On the other hand, in the command room (2) there is a position determination device that determines the current position of each worker (30) under the control of the CPU (61) based on signals from receivers (4) placed in each reception area (3). (7), and a CRT or other screen display device (8) that displays the current position of each worker (30).Furthermore, the control room (2) is equipped with a disaster detection sensor (5).
) Disaster prevention that calculates the type and location of a disaster based on signals detected by the system.

A processing device (9) and a transmission system that issues instructions to workers (30) to carry out disaster prevention activities when the occurrence of a disaster is detected, or to guide them to evacuate from the optimal route. A speaking device α is provided. Even if the transmitting device tS is a broadcasting device that gives commands and guidance to the worker (30) through a speaker (11) installed in a suitable reception area (3),
Alternatively, a wireless communication device may be used in which each worker (30) carries a wireless communication device and can communicate individually between each worker (30) and the control room (2).

(Function) With this structure, when a fire breaks out inside the building, the heat detection and smoke detectors among the disaster detection sensors (5) are activated, and the disaster prevention processing device (9) is activated. The disaster prevention processing device (9) and CPU f6) analyze and judge these signals and display the situation and location of the fire outbreak on the screen display device (8). On the other hand, the current position of each worker (30) working inside the building is determined by the infrared receiving element of the receiver installed in each receiving area (3) inside the building. Detects infrared rays generated from
After converting it into an electrical signal, the position determination device (
7) is constantly controlled in the control room (2) and is input to the CPU (61), so the C
P U (6) calculates the optimal evacuation route based on the situation and location of the fire outbreak and the current position of each worker, and displays the fire situation and each worker's (30) on the screen display device (8). Displays current location and evacuation route. The supervisor in the command room (2) uses the transmitter α0) to give each worker (30) the best evacuation guidance corresponding to his or her current position while watching the display on the screen display device (8). In addition, if a worker (30) is nearby immediately after a fire occurs, or if an abnormal temperature rise is detected before the fire occurs, □ is a transmitter (GO) to notify the worker. It is also possible to order disaster prevention activities such as fire extinguishing and inspections. Furthermore, if a specific worker falls unconscious, other workers can be ordered to rescue them, and even if a worker loses visibility due to smoke, the command center (2 ) can monitor its current position, and can also instruct the direction in which it should evacuate using the transmitting device 00).

(Effects of the Invention) As is clear from the above description, the present invention allows the control room to constantly monitor the position of each worker inside a building by detecting infrared rays generated from the worker's body. Therefore, when ordering for a disaster, appropriate commands and guidance can be given according to the position of each worker, which is effective in preventing the occurrence of fatal accidents. In addition, with the present invention, it is only necessary to install a receiver in each reception area inside the building, so installation in existing buildings is easy and the system has a long lifespan. There is no need to carry a transmitter, so there is no hassle during work, and there is no need for a power source for the transmitter, so there are no restrictions on usage time.In addition, it can sense the body temperature of an intruder from outside and detect the intruder. Another advantage is that it can be monitored from the control room.

Therefore, the present invention is extremely suitable as a disaster prevention monitoring and guidance system for a relatively small number of workers engaged in work such as patrolling and inspecting inside specific buildings such as underground substations, buildings, underground malls, and tunnels. It is something that
