It is a figure which shows the system configuration | structure of the operation control apparatus of the elevator which concerns on Example 2. FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a system configuration of an elevator operation control apparatus according to Example 1 of the present embodiment.

  In FIG. 1, the elevator operation control device includes an elevator EL and a terminal 10. The elevator EL includes a car frame 26 that moves up and down in the tower 25, a car 27 that is supported by an elastic support member 29 in the car frame 26, and a load sensor 21 that detects a load on the car 27. The car 27 is provided with a door 28 for passengers to enter and exit, a door motor 24 for opening and closing the door, and a closing switch 23 for confirming that the door is closed. The elevator control of the elevator EL is performed by the elevator controller 20, and a hall button 22 is installed in the elevator hall on each floor of the building where the elevator EL hoistway is installed.

  The terminal 10 includes a door signal input unit 1, a hall call input unit 2, a loading load input unit 3, a number calculation unit 4, a total number calculation 6, a reference floor calculation unit 7, a time management unit 8, and a vehicle allocation floor (reference floor) change unit. 9 is provided. A signal from the closing switch 23 is input to the door signal input unit 1, and an output signal from the door signal input unit 1 is input to the number calculation unit 4. The input calculation unit 4 also receives an output signal from the loaded load input unit 3 to which an output signal from the load sensor 21 is input. An operation signal from the hall button 22 is input to the hall call input unit 2, and output signals from the number calculation unit 4 and the hall call input unit 2 are input to the number integrating unit 6.

  The accumulated data 6a of the number of people loading unit 6 is input to the reference floor calculation unit 7, and the planned vehicle allocation floor (reference floor) data calculated by the reference floor calculation unit 7 is input to the vehicle allocation floor change unit 9, and the time management unit 8 Are output to the elevator control unit 20 together with the day of the week and time input from the vehicle, and the control of the elevator EL is executed.

  The details of the control of the elevator control device generally configured as described above are as follows.

  In FIG. 1, a call is generated when the hall button 22 is pressed, and the elevator controller 20 starts the car 27 and stops when it reaches the floor to be stopped. After the stop, the door motor 24 starts to rotate in the opening direction, and the closing switch 23 is turned off when the door 28 moves in the opening direction. With this as a trigger, the load input unit 3 starts to operate, and the load sensor 21 measures the load loaded on the car 27. Then, by dividing the measured load by, for example, 65 kg as the standard weight, the number of passengers in the car 27 is obtained. The number of passengers and the number of people getting off at the floor where the car 27 is stopped are calculated by the number-of-passengers calculation unit 4 from the number of passengers.

  FIG. 2 is an explanatory diagram showing a method for calculating the number of people. In the same figure, the horizontal axis represents time, the vertical axis represents the loaded load (number of passengers), and the load change from just before arrival to the floor where the car 27 is located until immediately after departure is shown along with the opening / closing timing of the door 27.

  A closing signal 32 from the closing switch 23 represents a temporal change of the closing switch 23, and is turned off when the door is opened and turned on when the door is closed. The load signal 30 from the load sensor 21 indicates the arrival number 34a when the door 33a is opened, and the departure number 34c when the door 33b is closed. Usually, passengers get off once and get on after a while. That is, there is a time lag between the number of people getting off and the number of people getting on, so the minimum number of people 34b is measured immediately after the passenger gets off.

  Therefore, the number obtained by subtracting the minimum number of people 34b from the number of people 34a upon arrival is the number of people getting off 34e, and the number obtained by subtracting the minimum number of people 34b from the number 34c on departure is the number of passengers 34f. At this time, the load signal 30 changes the waveform due to the load change caused by the passenger getting on and off and the vertical movement of the car 27 due to the influence of the load change. Measure. The arrival time number 34a, the minimum number of people 34b, and the departure time number 34c are calculated based on the point 31 of the load 0 by the passenger.

  Conventionally, since the difference number 34d obtained by subtracting the arrival number 34a from the departure number 34c was measured as the number of passengers, the getting-off number 34e was measured as an error, but by measuring as in the present embodiment, The number of passengers 34f is accurately measured.

  FIG. 3 is an explanatory diagram showing the contents of the integrated data 6a, and FIG. 4 is an explanatory diagram showing the contents of the reference floor schedule 7a. The number integrating unit 6 adds up the number of passengers as integrated data 6a. In the present embodiment, for example, as shown in FIG. 3, the accumulated data 6 a adds the number of passengers 34 f to the number of passengers 41 by time of day for each day of the week, floor, getting on and off, and time of day. The reference floor schedule 7a refers to the past integrated data 6a, and determines, for example, a floor set as a reference floor (allocation floor) for each day of the week, floor, and time zone as shown in FIG.

  For example, in the case of 11:00 on Monday, the number of passengers 34f from the first floor is large, so the first floor is assumed to be the planned dispatch floor 45a. In the case of 12:00 on Monday, since the number of passengers 34f from the n-th floor is large, the n-th floor is assumed to be a planned dispatch floor 45b. In the case of 13:00 on Monday, the number of passengers 34f is higher on the 3rd floor, so the 3rd floor is assumed to be a planned dispatch floor 45c. Therefore, the vehicle allocation floor changing unit 9 reads the standard floor schedule 7a and sends the day and time to the elevator control unit 20 in accordance with the day and time managed by the time management unit 8 as shown in FIGS. Give another dispatch instruction. The elevator control unit 20 moves the car 27 to the reference floor (vehicle allocation floor) when the vehicle can be allocated.
