Detailed Description

The invention is described with reference to the accompanying drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, the same reference numerals denote the same or equivalent parts.

Embodiment mode 1

Fig. 1 and 2 are diagrams showing an example of an elevator apparatus according to embodiment 1. The elevator installation comprises, for example, a car 1 and a counterweight 2. The car 1 moves up and down in the hoistway 3. The counterweight 2 moves up and down in the hoistway 3. The car 1 and the counterweight 2 are suspended in the hoistway 3 by the main ropes 4.

The main ropes 4 are wound around a drive sheave 6 of a hoisting machine 5. The car 1 moves in accordance with the rotation of the drive sheave 6. The control device 7 controls the rotation and stop of the drive sheave 6. That is, the car 1 is controlled by the control device 7.

Fig. 1 shows an example in which a hoisting machine 5 and a control device 7 are installed in a machine room 8 above a hoistway 3. The hoisting machine 5 and the control device 7 may be installed in the hoistway 3. When the hoisting machine 5 is installed in the hoistway 3, the hoisting machine 5 may be disposed at the ceiling of the hoistway 3 or may be disposed in the pit 3a of the hoistway 3.

The car 1 includes, for example, a display 11, an operation panel 12, and a weighing device 13. The display 11 is disposed inside the car 1. The display 11 provides information to the person riding in the car 1.

The operation panel 12 is a device for registering calls to a plurality of floors by a person riding the car 1. Signals from the operation panel 12 are input to the control device 7. For example, the operation panel 12 includes destination buttons for each floor at which the car 1 stops. When a destination button of floor 3 is pressed in the car 1 in the case where the car 1 stops at floors 1 to 5, a call of floor 3 is registered. When a destination button at floor 5 is pressed in the car 1, a call at floor 5 is registered.

The weighing device 13 detects the load of the car 1. The signal from the weighing device 13 is input to the control device 7. Fig. 1 shows an example in which the weighing device 13 is disposed below the car floor. As another example, the weighing device 13 may be provided at an end of the main rope 4. In this case, the weighing device 13 may not be provided in the car 1.

The control device 7 includes, for example, a storage unit 20, a detection unit 21, an arithmetic unit 22, an arithmetic unit 23, and a display control unit 24.

The storage unit 20 stores an evaluation value table. Table 1 shows an example of the evaluation value table. The evaluation value table shown in table 1 is stored in the storage unit 20 of an elevator apparatus provided in, for example, an office building a. For example, office building a has floor 1 as a lobby. Warehouse and rest room are equipped with on 2 floors of office building A, are equipped with office B on 3 floors, are equipped with office C on 4 floors. In addition, conference rooms are provided on 5 levels.

[ Table 1]

In the evaluation value table, evaluation values for each time slot are set for each floor at which the car 1 stops. The evaluation value is, for example, a value based on the number of calls registered from the operation panel 12. The example shown in table 1 shows that 8 calls of 3 floors are registered on average from the operation panel 12 at 8-point periods. Similarly, the example shown in table 1 shows that 7 average floor-1 calls were registered from the operating panel 12 over a period of 18 points. The evaluation value is set based on, for example, a past actual value.

Hereinafter, the functions of the elevator apparatus will be described with reference to fig. 3. Fig. 3 is a flowchart showing an operation example of the elevator apparatus according to embodiment 1. In particular, fig. 3 shows the function of the control device 7 controlling the display 11.

The control device 7 determines whether or not there is a call registered from the operation panel 12 (S101). If yes is determined in S101, the control device 7 determines whether or not there are a plurality of calls registered from the control panel 12 (S102). When the number of calls registered from the operation panel 12 is 1 (no in S102), the detection unit 21 detects the number of people riding in the car 1 (S103). For example, the detection unit 21 detects the number of people based on the load detected by the weighing device 13. The indication control section 24 performs first indication control based on the floor on which the call is registered from the operation panel 12 and the number detected by the detection section 21 (S104). The floor at which a call is registered from the operation panel 12 is a floor at which the car 1 will stop from now on.

For example, consider a case where 1 person enters the unmanned car 1 from floor 1 in an office building a and presses a destination button on floor 3 of the operation panel 12. In this case, a call of 3 floors is registered, and the first display control is performed in S104. Fig. 4 is a diagram showing an example of display before the first display control is performed. For example, if a call from the operation panel 12 is not registered, the indication control section 24 indicates a plan view of the inside of the car 1 on the display 11.

Fig. 5 is a diagram showing an example of display under the first display control. The indication control unit 24 causes the indicator 11 to display a region indicating the seating position of a person getting off the car 1 at 3 floors in the car 1, so as to overlap with a plan view of the inside of the car 1. Hereinafter, a region indicating the seating position in the car 1 is also referred to as "riding region". For example, a region indicating a riding position in the car 1 of a person who gets off the car 1 at 3 floors is expressed as "riding region (3 floors)". Similarly, a region indicating a riding position in the car 1 of a person who gets off the car 1 at 5 floors is expressed as "riding region (5 floors)". In S104, the display control unit 24 displays the boarding area (3 floors) at a position close to both the entrance and the operation panel.

On the other hand, if yes is determined in S102, the detection unit 21 detects the number of people riding in the car 1 (S105). Further, the control device 7 determines whether or not the number detected by the detection section 21 is greater than the number of calls registered from the operation panel 12 (S106). When all the persons riding in the car 1 move to different floors, the determination in S106 is no. If it is determined as no in S106, the indication control section 24 performs second indication control based on the floor on which the call is registered from the operation panel 12 (S107).

For example, consider a case where 2 persons enter the unmanned car 1 from floor 1 in an office building a, and press the destination button at floor 3 and the destination button at floor 5 of the operation panel 12. In this case, a 3-floor call and a 5-floor call are registered, and after a determination of no in S106, the second display control is performed in S107. Fig. 6 is a diagram showing an example of display under the second display control. The display control unit 24 displays the boarding area (3 floors) and the boarding area (5 floors) on the display 11 so as to overlap each other in a plan view of the car 1. For example, the size D of the riding area for 1 person is set in advance according to the rated number of persons of the car 1. In S107, the display control unit 24 causes the display 11 to display the boarding area (3 floors) and the boarding area (5 floors) having the size D.

If it is determined as yes in S106, the number detected by the detection unit 21 is greater than the number of calls registered. For example, if there is a person who does not press the destination button among the persons who get on the car 1, it is determined as yes in S106. In this case, the display control unit 24 performs the third display control based on the current time, the evaluation value table stored in the storage unit 20, and the number detected by the detection unit 21 (S108). In the third indication control, for each floor at which a call is registered from the operation panel 12, an elevator boarding area indicating a riding position in the car 1 is displayed on the display 11. The current time can be obtained from a clock function provided in the control device 7.

Fig. 7 is a flowchart showing an example of the third display control. For example, if it is determined as yes in S106, the calculation unit 22 calculates the size ratios of a plurality of boarding areas displayed on the display 11 (S201). The calculation unit 22 performs the calculation of S201 based on the current time and the evaluation value table.

For example, consider a case where 3 persons enter the unmanned car 1 from floor 1 and press the destination button at floor 3 and the destination button at floor 5 of the operation panel 12 at

point

8 and 30 in the office building a. In this case, a 3-floor call and a 5-floor call are registered, and it is determined as yes in S106. In this example, 1 person out of 3 persons who get on the car 1 at floor 1 does not press the destination button. Therefore, it is not known at which floor the person who has not pressed the destination button gets off the car 1. However, the person may descend from the car 1 at 3 or 5 floors. In this case, the third display control is performed.

As shown in table 1, in the evaluation value table stored in the storage section 20, the evaluation value of 3 layers for the 8-dot period is 8. In addition, the evaluation value of 5 layers of the 8-dot period is 3. For example, in S201, the calculation unit 22 calculates the size ratio of the boarding area (3-level) to the boarding area (5-level) to be displayed on the display 11 as 8: 3. as another example, the calculation unit 22 may calculate the ratio by dividing the number detected by the detection unit 21 into ratios closest to the evaluation values. For example, the calculation unit 22 calculates the size ratio of the boarding area (3-level) to the boarding area (5-level) to be displayed on the display 11 as 2: 1.

next, the calculation unit 23 calculates the size of each boarding area to be displayed on the display 11, based on the ratio calculated by the calculation unit 22 and the number detected by the detection unit 21 (S202). In the above example, the number detected by the detection unit 21 is 3. When the ratio obtained by the calculation unit 22 is 8: in case 3, the calculation unit 23 calculates the size of the boarding area (3 floors) to be 3D × 8/11. The calculation unit 23 calculates the size of the boarding area (5 floors) to be 3D × 3/11. As another example, when the ratio obtained by the calculation unit 22 is 2: in case 1, the calculation unit 23 calculates the size of the boarding area (3 floors) to be 3D × 2/3. The calculation unit 23 calculates the size of the boarding area (5 floors) to be 3D × 1/3.

Fig. 8 is a diagram showing an example of display under the third display control. The display control unit 24 displays each boarding area on the display 11 based on the size calculated by the calculation unit 23 (S203).

Fig. 9 is a flowchart showing another operation example of the elevator apparatus according to embodiment 1. Fig. 9 shows an operation flow performed when a call registered from the operation panel 12 already exists. The process shown in S301 of fig. 9 corresponds to the process shown in S101 of fig. 3. The processes illustrated in S302 to S305 of fig. 9 correspond to the processes illustrated in S105 to S108 of fig. 3.

For example, when the display shown in fig. 8 is performed, the control device 7 determines whether or not there is a call newly registered from the operation panel 12 (S301). If yes is determined in S301, the detection unit 21 detects the number of people riding in the car 1 (S302). If yes is determined in S301, it is determined whether or not the number of people who newly get on the car 1 (the number of increased people) is greater than the number of newly registered calls (the number of increased calls) (S303). If it is determined as no in S303, the second display control is performed. If it is determined as yes in S303, the third display control is performed.

For example, after the display shown in fig. 8 is performed, a person 1 is riding in the 2-floor car 1, and the person presses the destination button on the 4-floor. In this case, the determination at S303 is no, and the second display control is performed at S304. Fig. 10 is a diagram showing another display example under the second display control. The display control unit 24 additionally displays the boarding area (4 floors) having the size D on the display 11, for example. Fig. 10 shows an example in which the display control unit 24 displays the boarding area of the floor at which the car 1 stops at the earliest timing as being closest to the doorway.

Fig. 11 is a diagram showing another display example. Fig. 11 shows an example of the display when the car 1 stops at the floor 3 after the display shown in fig. 10 is performed. When the car 1 stops at the 3 rd floor, the display control section 24 deletes the boarding area (3 rd floor) from the display 11.

In the example shown in the present embodiment, the indication of the riding position in the car 1 can be appropriately displayed according to the situation. Therefore, passengers can smoothly get on and off the car 1. In addition, the waiting time at the landing is reduced, and the operating efficiency is improved.

Other functions that can be employed by the elevator apparatus will be described below.

As shown in fig. 2, the control device 7 may further include a detection unit 25 and a setting unit 27. The setting unit 27 has a function of setting an evaluation value to the evaluation value table stored in the storage unit 20. Fig. 12 is a flowchart showing an example of the evaluation value setting function of the control device 7.

The detection unit 25 detects the number of calls registered from the operation panel 12 for each floor at which the car 1 stops (S401). Then, the setting unit 27 sets an evaluation value to the evaluation value table based on the result detected by the detection unit 25 (S402). For example, the setting unit 27 sets the average value of the numbers detected by the detection unit 25 as an evaluation value in the evaluation value table. In this example, the evaluation value can be set according to the number of calls actually registered from the operation panel 12.

As another example, the evaluation value set in the evaluation value table may be a value based on the number of persons getting off the car 1. Table 2 shows another example of the evaluation value table. Table 2 shows only a part of the evaluation value table.

[ Table 2]

The example shown in table 2 shows that on average 17 people are getting off the car 1 at 3 floors in an 8-point period. Likewise, the example shown in table 2 shows that 20 persons on average descend from the car 1 at floor 1 in the 9-point period.

When a value based on the number of persons getting off the car 1 is used as the evaluation value, the control device 7 may further include a detection unit 26 and a setting unit 27, as shown in fig. 2. Fig. 13 is a flowchart showing another example of the evaluation value setting function of the control device 7.

The detection unit 26 detects the number of persons getting off the car 1 in each time period from the number detected by the detection unit 21 for each floor at which the car 1 stops (S501). Then, the setting unit 27 sets an evaluation value in the evaluation value table based on the result detected by the detection unit 26 (S502). For example, the setting unit 27 sets the average value of the numbers detected by the detection unit 25 as an evaluation value in the evaluation value table. In this example, the evaluation value can be set according to the number of persons who actually get off the car 1.

As another example, the evaluation value set in the evaluation value table may be a value based on the number of persons getting off at each call. Table 3 shows another example of the evaluation value table. Table 3 shows only a part of the evaluation value table.

[ Table 3]

The example shown in table 3 shows that on average 2.1 people are getting off car 1 at 3 floors per call over an 8-point period. Likewise, the example shown in table 3 shows that on average 3.3 people are getting off car 1 at floor 1 per call over a 9-point period. The evaluation value table shown in table 3 is created using the values of the table shown in table 1 and the values of the table shown in table 2.

The third display control in the case where the evaluation value table shown in table 3 is stored in the storage unit 20 will be described below. As described above, when it is determined as yes in S106, the third display control is performed.

For example, consider a case where 3 persons enter the unmanned car 1 from floor 1 at

point

8 and 30 points in the office building a, and the destination button at floor 3 and the destination button at floor 5 of the operation panel 12 are pressed. As shown in table 3, in the evaluation value table stored in the storage section 20, the evaluation value of 3 layers for the 8-dot period is 2.1. In addition, the evaluation value of 5 layers of the 8-dot period is 4.3. For example, in S201, the calculation unit 22 calculates a ratio of the size of the boarding area (3 floors) to the size of the boarding area (5 floors) to be displayed on the display 11 to be 2.1: 4.3. as another example, the calculation unit 22 may calculate the ratio by dividing the number detected by the detection unit 21 to be closest to the ratio obtained from the evaluation value. For example, the calculation unit 22 calculates the ratio of the sizes of the boarding area (3-level) and the boarding area (5-level) to be displayed on the display 11 as 1: 2.

next, the calculation unit 23 calculates the size of each boarding area to be displayed on the display 11, based on the ratio calculated by the calculation unit 22 and the number detected by the detection unit 21 (S202). In the above example, the number detected by the detection unit 21 is 3. The ratio obtained by the calculation unit 22 is 2.1: in case of 4.3, the calculation unit 23 calculates the size of the boarding area (3 levels) to be 3D × 2.1/(2.1+ 4.3). The calculation unit 23 calculates the size of the boarding area (5 levels) to be 3D × 4.3/(2.1+ 4.3). As another example, when the ratio obtained by the calculation unit 22 is 1: in case 2, the calculation unit 23 calculates the size of the boarding area (3 floors) to be 3D × 1/3. The calculation unit 23 calculates the size of the boarding area (5 floors) to be 3D × 2/3. The display control unit 24 displays each boarding area on the display 11 based on the size calculated by the calculation unit 23 (S203).

When the value based on the number of persons getting off per call is used as the evaluation value, the control device 7 may further include a detection unit 25, a detection unit 26, and a setting unit 27 as shown in fig. 2. Fig. 14 is a flowchart showing another example of the evaluation value setting function of the control device 7.

The detection unit 25 detects the number of calls registered from the operation panel 12 for each floor at which the car 1 stops by time period (S601). The detection unit 26 detects the number of persons who get off the car 1 in each floor where the car 1 stops, based on the number detected by the detection unit 21, in each time period (S602). Then, the setting unit 27 sets an evaluation value in the evaluation value table based on the result detected by the detection unit 25 and the result detected by the detection unit 26 (S603). For example, the setting unit 27 sets a value obtained by dividing the average value of the numbers detected by the detection unit 26 by the average value of the numbers detected by the detection unit 25 in the evaluation value table as an evaluation value. In this example, the evaluation value can be set according to the number of persons actually getting off at each call.

In the present embodiment, an example in which evaluation values divided by time period are included in the evaluation value table is described. This is only one example. For example, the evaluation value table may include evaluation values that are divided by day of the week and divided by time period.

In the present embodiment, an example in which one evaluation value table is stored in the storage unit 20 is explained. This is merely an example. A plurality of evaluation value tables may be stored in the storage unit 20. For example, an evaluation value table used when the car 1 moves upward and an evaluation value table used when the car 1 moves downward may be stored in the storage unit 20.

In the present embodiment, each part shown by reference numerals 20 to 27 shows a function of the control device 7. Fig. 15 is a diagram showing an example of hardware resources of the control device 7. The control device 7 includes, as hardware resources, a processing circuit 30 including a processor 31 and a memory 32, for example. The function of the storage unit 20 is realized by the memory 32. The control device 7 realizes the functions of the respective sections denoted by reference numerals 21 to 27 by executing a program stored in the memory 32 by the processor 31.

Fig. 16 is a diagram showing another example of the hardware resources of the control device 7. In the example shown in fig. 16, the control device 7 includes a processing circuit 30 including, for example, a processor 31, a memory 32, and dedicated hardware 33. Fig. 16 shows an example in which a part of the functions of the control device 7 is realized by dedicated hardware 33. All functions of the control device 7 may be realized by dedicated hardware 33.
