Description

  The present invention relates to an elevator control device that controls the operation of a car that is dispatched to a landing.

  In the conventional device, the call is registered according to the operation of the landing call registration button or the destination floor button in the car, and the number of times of the operation is counted. (For example, refer to Patent Document 1).

JP 7-172744 A

  In the conventional elevator control apparatus as described above, the car door opening time is extended as prescribed even after the elevator user gets off, and the car door remains open for the extended time. Could not move up and down, and the waiting time of elevator users waiting at another landing was long.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an elevator control device that can shorten the waiting time of an elevator user waiting at a landing. .

  The elevator control device according to the present invention includes an operation number counting unit that counts the number of operations of a hall call registration button provided at a landing, and a door control unit that controls opening and closing of a car door. Depending on the number of operations counted by the operation number counting unit, the door opening time of the car dispatched to the landing is shortened from the normal door opening time.

  According to the elevator control device of the present invention, when the elevator user is waiting for the car at the landing, the elevator call can be moved up and down faster by operating the landing call registration button. Thus, the waiting time of the elevator user waiting at the landing can be shortened.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
1 is a block diagram showing an elevator control apparatus according to Embodiment 1 of the present invention. In the figure, a car 1 is provided with a car door 2, a car-side call registration button 3, a scale device 4, and the like. A landing-side call registration button 5 is provided at the landing on each elevator stop floor.

  The elevator controller 6 controls the raising and lowering of the car 1 and the opening and closing of the car door 2. The elevator control device 6 includes an operation control unit 7, a hall call registration unit 8, a destination floor call registration unit 9, a door operation management unit 10, and an operation frequency count unit 11.

  The hall call registration unit 8 inputs the operation of the hall side call registration button 5 to the operation control unit 7 and performs call registration. The destination floor call registration unit 9 inputs the operation of the car-side call registration button 3 to the operation control unit 7 and performs call registration. The operation control unit 7 controls the raising / lowering of the car 1 according to call registration. The operation control unit 7 also has a function of issuing a door opening command and a door closing command to the door operation management unit 10 in order to open and close the car door 2.

  The door control unit 12 that controls the opening and closing of the car door 2 includes an operation control unit 7 and a door operation management unit 10. The door operation management unit 10 controls a door motor (not shown) that drives the door 2 of the car according to the door opening command and the door closing command.

  The operation count section 11 counts the number of operations of the hall side call registration button 5. The number of operations performed by the operation number counting unit 11 is performed for each landing. In the operation count section 11, a reference operation count (threshold value) is set. When the operation of the hall side call registration button 5 is performed exceeding the set number of operations within a predetermined time, the operation number counting unit 11 inputs operation number information to the operation control unit 7. In addition, the operation number counting unit 11 inputs operation number information and also inputs multi-operation floor information to the operation control unit 7. The multi-operation floor information is information indicating where the hall where the operation of the hall-side call registration button 5 has been performed more frequently.

  The scale device 4 detects a load in the car 1. The load in the car 1 is input to the operation control unit 7 by the scale device 4.

  In the operation control unit 7, a normal door opening time from when the door opening command is issued until the door closing command is issued is preset.

  When the operation number information is input from the operation number counting unit 11 and the load in the car 1 is smaller than a preset set load, the operation control unit 7 takes a shorter time than the normal door opening time. A door closing command is issued to the door operation management unit 10 so as to close the door 2 (door opening shortening operation) (for example, a door closing command is issued in about 90% of the normal door opening time). Here, the set load is, for example, a load that can be determined that no elevator user has entered the car 1.

  Next, the operation will be described. FIG. 2 is a flowchart showing the operation of the elevator control apparatus of FIG. During normal operation, whether or not there is an operation of the hall side call registration button 5 is monitored by the operation number counting unit 11 (standby state) (step S101).

  At this time, when the landing-side call registration button 5 is operated, a call is registered in the operation control unit 7 and time is started to be measured by the operation count counting unit 11 (step S102). 5 operations are counted (step S103). Then, it is determined whether or not the number of operations of the hall-side call registration button 5 exceeds the set number of operations by the operation number counting unit 11, and whether or not the operation number information is input is monitored by the operation control unit 7 (step) S104).

  At this time, if the number of operations of the landing side call registration button 5 does not exceed the set number of operations, the operation number counting unit 11 monitors whether the landing side call registration button 5 is operated again within a predetermined time. (Step S105). If the hall call registration button 5 is not operated again within a predetermined time, the operation is terminated and the standby state is restored. On the other hand, when the operation of the hall side call registration button 5 is performed again within a predetermined time, the operation count counting unit 11 starts to measure the time again (step S102), and the operation of the hall side call registration button 5 is performed. It is counted (step S103), it is determined whether or not the number of operations of the hall side call registration button 5 exceeds the set number of operations, and the operation control unit 7 monitors whether or not the operation number information is input (step S103). S104).

  Next, when the number of operations of the hall-side call registration button 5 exceeds the set number of operations and the operation number information is input to the operation control unit 7 by the operation number counting unit 11, the operation control unit 7 loads the load in the car 1. Is smaller than the set load (step S106).

  At this time, if the load in the car 1 is larger than the set load, the operation is terminated and the process returns to the standby state. On the other hand, when the load is smaller than the set load, the operation control unit 7 performs a setting for performing the door opening shortening operation.

  When the car 1 arrives at each landing and the car door 2 is opened, the operation control unit 7 performs a door opening shortening operation and closes the door in a time shorter than the normal door opening time ( Step S107). The door opening shortening operation performed by the operation control unit 7 is performed until the car 1 arrives at the landing corresponding to the multi-operation floor information.

  In such an elevator control device, when the elevator user is waiting for the car 1 at the landing, the elevator-side call registration button 5 is operated, so that the elevator that is open on another floor can be moved up and down more quickly. Thus, the waiting time of the elevator user waiting at the landing can be further shortened.

  Further, the load in the car 1 is detected by the scale device 4, and the car door 2 is closed in a time shorter than the normal door opening time by the operation control unit 7 in accordance with the load in the car 1. A door closing command is issued. That is, it is possible to prevent the car door 2 of the car 1 that is not used by anyone from being opened more than necessary, and to provide a more efficient elevator service.

  In the first embodiment, the operation control unit 7 shortens the time from issuing the door opening command to issuing the door closing command. However, the door control unit may increase the operation speed of the car door (for example, increase the speed by about 10%), thereby shortening the car door opening time.

  In the first embodiment, the operation control unit 7 closes the door 2 in order to close the car door 2 in a time shorter than the normal door opening time according to both the operation frequency information and the load in the car 1. The order was issued. However, the door control unit may shorten the door opening time of the car from the normal door opening time according to only one of the operation frequency information and the load in the car 1. That is, an elevator control device corresponding to information on only one of the operation number counting unit and the scale device may be used.

  Furthermore, in the first embodiment, the operation number counting unit 11 notifies the operation control unit 7 of the operation number information when the number of operations of the hall-side call registration button 5 reaches a preset number of operation operations within a predetermined time. It was issued. Here, the number of set operations is not limited to one, and operation number information may be issued stepwise in accordance with the number of operations of the hall side call registration button (for example, the hall side call registration button is operated once). You may issue the operation count information every time). And a door control part may shorten the door opening time of a car in steps rather than normal door opening time by receiving operation frequency information in steps.

Furthermore, in the first embodiment, the set load preset in the operation control unit 7 is a load that can be determined that no elevator user has entered the car 1, and the operation control unit 7 The door opening shortening operation was performed when the load in the car 1 was smaller than the set load. However, the door control unit should shorten the door opening time of the car according to the load in the car,
When the load in the car is larger than the set load, the car door opening time may be shortened. The set load at this time is, for example, a load that can be determined that the car is almost full.

Embodiment 2. FIG.
FIG. 3 is a block diagram showing an elevator control apparatus according to Embodiment 2 of the present invention. In this example, a plurality of cars 1a and 1b are operated in parallel. The operations of the cars 1a and 1b are controlled by operation control units 7a and 7b, respectively. The operations of the respective operation control units 7a and 7b are controlled by the group management control unit 14.

  The elevator control device 15 is provided with a hall call registration unit 8 and an operation frequency counting unit 11. The hall call registration unit 8 and the operation frequency counting unit 11 are connected to the group management control unit 14. Accordingly, the operation of the hall side call registration button 5 provided at each hall in the building and the multi-operation floor information are input to the group management control unit 14.

  Scales 4a and 4b are provided on the cars 1a and 1b, respectively. The scale devices 4 a and 4 b are also electrically connected to the group management control unit 14. The scale devices 4a and 4b detect loads in the cars 1a and 1b. That is, it is detected how many elevator users can enter the cars 1a and 1b.

  The group management control unit 14 selects the most suitable car 1a, 1b from the position and driving direction according to the operation of the hall side call registration button 5, and dispatches the cars 1a, 1b to the hall where the elevator user waits. To do. Furthermore, the group management control unit 14 gives priority to the plurality of cars 1a and 1b in order of increasing load in the cars 1a and 1b (optimal order) with respect to the hall informed by the multi-operation floor information. Can be dispatched. Other configurations are the same as those of the first embodiment.

  Next, the operation will be described. FIG. 4 is a flowchart showing the operation of the elevator control apparatus of FIG. In the figure, first, the state (position, driving direction, and load status) of each of the cars 1a and 1b is confirmed by the group management control unit 14 (step S201). Next, similarly to the operation control unit 7 of the first embodiment, the group management control unit 14 monitors whether the landing side call registration button 5 and the car side call registration button 3 (not shown) are operated. (Steps S202 and S203). If there is no operation of the hall side call registration button 5 and the car side call registration button 3, this monitoring is repeated (standby state).

  At this time, when the landing side call registration button 5 is operated at any of the landings and the call registration is performed, the multi-operation floor information is then sent from the operation count counting unit 11 by the group management control unit 14. It is confirmed whether it has not come (step S204). Here, if the multi-operation floor information is not input, either the car 1a or 1b is dispatched to the hall where the hall-side call registration button 5 is operated (step S205). When the elevator user gets into the cars 1a and 1b and the car-side call registration button 3 is operated, the cars 1a and 1b are dispatched according to the call registration (step S205).

  On the other hand, when the hall-side call registration button 5 is operated more than the set number of operations within a predetermined time, the multi-operation floor information is input to the group management control unit 14 by the operation number counting unit 11.

  At this time, even if an elevator user at a plurality of halls operates each of the hall side call registration buttons 5, the group management control unit 14 installs the cars 1a and 1b at the hall according to the multi-operation floor information. Cars are dispatched preferentially in the optimal order (step S206).

  In such an elevator control device, the group management control unit 14 responds to the multi-operation floor information sent from the operation number counting unit 11 to the platform 1a where the landing call registration button 5 is more frequently operated. , 1b is assigned with priority, the waiting time at the elevator user's landing can be shortened, and a more efficient elevator service can be provided.

  In addition, since the group management control unit 14 dispatches the plurality of cars 1 in the optimum order according to the multi-operation floor information, even if the elevator user cannot get through with one dispatch, the next car is dispatched. Since it is possible to get on the incoming cars 1a and 1b, the waiting time at the elevator user's landing can be shortened, and a more efficient elevator service can be provided.

  Furthermore, since the group management control unit 14 gives priority to the cars 1a and 1b on which more elevator users can board in accordance with the multi-operation floor information and the load in the car 1, the elevator users can use the elevator. The possibility of not being able to ride is reduced, and a more efficient elevator service can be provided.

In the second embodiment, the door opening times of the cars 1a and 1b are not changed. However, the group management control unit in the second embodiment may also serve as the operation control unit in the first embodiment, and the floor time of the car door may be shortened.
