Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to an elevator operation dispatching system and a dispatching method. Background Art

[0002] Elevators are essential means of transportation in modern buildings, providing vertical transportation services for different passengers. In comprehensive business buildings, it is necessary to provide special fast elevator services for specific VIP passengers. Generally, comprehensive business buildings are composed of multiple elevators to provide transportation services in order to improve the overall transportation efficiency. When the group control system learns that there is a VIP passenger service demand through the VIP specific calling device, the current common processing methods are as follows:

[0003] VIP service elevators are group-controlled special elevators. Special elevators no longer respond to floor station calls, cannot register new car calls, and will go to the VIP floor to serve VIP passengers after serving existing car calls. This method is likely to cause VIP passengers to wait too long during rush hour and lunch peak hours in the building.

[0004] VIP service elevators are group-controlled special elevators. When dispatching and allocating elevators, the group control system reduces the weight coefficient of special elevators serving ordinary calls, and gives priority to allocating ordinary calls to non-specific elevators, making it difficult for special elevators to serve ordinary calls. On this basis, when there is a special call, the special elevator can shorten the waiting time of the special VIP passengers. This method will reduce the transportation efficiency of the group elevators when there is no special VIP passenger call.

[0005] The VIP service elevator is any elevator in the group control system. The group control system calculates the service time required for each elevator in the group to complete the car call, and selects the elevator with the shortest service time to serve the VIP passengers. This method cannot effectively solve the problem of VIP passengers waiting too long during rush hour and lunch rush hour in the building, and it also makes it difficult for VIP passengers to determine which elevator in the group serves them.

[0006] The group control system instructs specific elevators to go to the VIP floor and wait in advance. Although this method can solve the waiting time of VIP passengers, it will seriously reduce the transportation efficiency of the group elevators. Summary of the invention

[0007] The purpose of the present invention is to propose an elevator operation dispatching system and dispatching method to solve the problem that when VIP passengers and ordinary passengers use the elevator together, the waiting time of VIP passengers cannot be shortened and the transportation efficiency of group elevators for ordinary passengers cannot be reduced.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] An elevator operation dispatching system, comprising:

[0010] Group control dispatcher: The group control dispatcher is responsible for dispatching and allocating elevator groups;

[0011] Elevator controller: the elevator controller is responsible for the elevator operation control;

[0012] Common call registration device, each elevator in the group is equipped with a common call registration device at the service floor station, the common call registration device is connected to the elevator controller and transmits the floor station call information to the elevator controller, the elevator controller is connected to the group control dispatcher and transmits the floor station call information to the group control dispatcher;

[0013] VIP call registration device, VIP call registration device is only set up at the VIP service floor station and is only connected to the VIP elevator controller in the group. The VIP call registration device can identify VIP passengers of different levels. The VIP call device transmits the VIP passenger call information to the group control dispatcher through the elevator controller;

[0014] A car call registration device is provided for each elevator car in the group, and the car call registration device transmits the car call information to the group control dispatcher through the elevator controller;

[0015] The car prompt device is installed in the VIP elevator car. When the VIP elevator is in normal service, it displays the running direction and floor information. When ordinary passengers need to transfer for VIP special service, it also displays the transfer stop floor and transfer elevator information.

[0016] Furthermore, the group control scheduler includes:

[0017] The communication unit is used to receive the common landing call information, VIP landing call information and car call information transmitted by the elevator controller;

[0018] VIP passenger registration table, which is used to store the preset waiting time values ​​of VIP passengers of different levels;

[0019] VIP passenger waiting time calculation unit, which is used to calculate the VIP passenger waiting time value according to the different levels of VIP passengers and the busyness of the group control elevator;

[0020] VIP Passenger Estimated Waiting Time Assessment Department, which assesses the time required for the VIP elevator to reach the VIP call floor after serving all ordinary car calls, i.e. the VIP passenger estimated waiting time;

[0021] The dispatching and allocation department compares the estimated waiting time of VIP passengers with the waiting time value of VIP passengers, reallocates the car call of the VIP elevator to other elevators in the group, and outputs the allocation result to the elevator controller.

[0022] Furthermore, the VIP passenger registration table records VIP passengers of different levels, and VIP passengers of different levels correspond to different VIP preset waiting time values, wherein the higher the level of the VIP passenger, the shorter the VIP preset waiting time value corresponding to the VIP passenger.

[0023] Furthermore, the dispatching system adds an adjustment factor to the VIP preset waiting time value according to the busyness of the group elevator service to obtain the VIP waiting time, that is, VIP waiting time = VIP preset waiting time × adjustment factor.

[0024] Furthermore, the adjustment factor can be adjusted according to the busyness of the group elevator service. When the group elevator service is busy, the adjustment factor is greater than 1, and when the group elevator service is idle, the adjustment factor is less than 1.

[0025] Furthermore, the dispatching method of the elevator operation dispatching system comprises the following steps:

[0026] S1: The VIP passenger registers the VIP call in the VIP call registration device, and the VIP call registration device transmits the VIP call registration signal to the group control dispatcher through the VIP elevator controller;

[0027] S2-1: If the VIP elevator has been assigned a common landing call, the VIP elevator will no longer respond to the common landing call, and the group control dispatcher will reallocate the common landing call of the VIP elevator to other elevators in the group;

[0028] S2-2: If the VIP elevator has registered a common car call, the group control dispatcher estimates the time required for the VIP elevator to reach the VIP calling floor after serving all common car calls, i.e. the estimated waiting time for the VIP passenger, based on the VIP elevator's running direction and the distribution of car calls;

[0029] S2-3: If the estimated waiting time of the VIP passenger is greater than the VIP waiting time value, the group control dispatcher will dispatch the farthest ordinary car calls of the VIP elevator to other suitable elevators in the group along the direction of elevator operation, and re-evaluate the estimated waiting time of the VIP passenger until the estimated waiting time of the VIP passenger is less than or equal to the VIP waiting time value. After the VIP elevator has served the remaining ordinary car calls, it will stop and open the door. The group control dispatcher will notify the ordinary passengers of the latest dispatch transfer information through the VIP car prompt device through text, graphics, voice, etc. to transfer to other elevators in the group. The VIP elevator will no longer respond to ordinary floor station calls. After the ordinary passengers leave the car, it will close the door and go directly to the VIP service floor;

[0030] If the number of remaining ordinary car calls that the VIP elevator responds to is 0, the estimated waiting time of VIP passengers can be less than or equal to the VIP waiting time value. Then the group control dispatcher instructs the VIP elevator to stop and open the door at the nearest floor. After the ordinary passengers leave the car, the door is closed and the elevator goes directly to the VIP service floor to ensure that the VIP elevator can provide VIP services in the shortest time.

[0031] S2-4: If the estimated waiting time of the VIP passenger is less than the VIP waiting time value, the VIP elevator will no longer respond to ordinary landing calls, and will go to the VIP service floor after serving all ordinary car calls, so as to reduce the impact on the transportation efficiency of ordinary passengers;

[0032] S2-5: The group control dispatcher instructs other elevators in the group that have been allocated to the VIP elevator's ordinary car call to go to the VIP elevator transfer landing floor. After arriving, they open the door and automatically register the transfer passengers' destination floor to facilitate the transfer passengers to use the elevator.

[0033] S3: If the VIP elevator has not registered an ordinary car call and is heading to respond to an assigned ordinary floor call, the group control dispatcher will reallocate the ordinary floor call assigned to the VIP elevator to other elevators in the group, and dispatch the VIP elevator to go directly to the VIP service floor, and will no longer respond to ordinary floor calls.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] The present invention solves the scheduling and allocation problem when VIP passengers and ordinary passengers use elevators at the same time, so that VIP passengers can take the elevator within the scheduled time, while reducing the impact of reduced transportation efficiency on ordinary passengers, thereby maximizing the overall use efficiency of the group elevators.

The group control dispatcher will send the latest dispatch transfer information, such as Figure 4 As shown, the VIP car prompt device notifies ordinary passengers to transfer to other elevators in the group through text, graphics, voice, etc., and the VIP elevator no longer responds to ordinary floor station calls. After ordinary passengers leave the car, the door closes and they go directly to the VIP service floor;

[0065] If the number of remaining ordinary car calls that the VIP elevator responds to is 0, the estimated waiting time of VIP passengers can be less than or equal to the VIP waiting time value. Then the group control dispatcher instructs the VIP elevator to stop and open the door at the nearest floor. After the ordinary passengers leave the car, the door is closed and the elevator goes directly to the VIP service floor to ensure that the VIP elevator can provide VIP services in the shortest time.

[0066] S2-4: If the estimated waiting time of the VIP passenger is less than the VIP waiting time value, the VIP elevator will no longer respond to ordinary landing calls, and will go to the VIP service floor after serving all ordinary car calls, so as to reduce the impact on the transportation efficiency of ordinary passengers;

[0067] S2-5: The group control dispatcher instructs other elevators in the group that have been allocated to the VIP elevator's ordinary car call to go to the VIP elevator transfer landing floor. After arriving, they open the door and automatically register the transfer passengers' destination floor to facilitate the transfer passengers to use the elevator.

[0068] S3: If the VIP elevator has not registered an ordinary car call and is heading to respond to an assigned ordinary floor call, the group control dispatcher will reallocate the ordinary floor call assigned to the VIP elevator to other elevators in the group, and dispatch the VIP elevator to go directly to the VIP service floor, and will no longer respond to ordinary floor calls.

[0069] The present invention solves the scheduling and allocation problem when VIP passengers and ordinary passengers use elevators at the same time, so that VIP passengers can take the elevator within the scheduled time, while reducing the impact of reduced transportation efficiency on ordinary passengers, thereby maximizing the overall use efficiency of the group elevators.
