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 transportation in modern buildings, providing vertical transportation services for a variety of passengers. In commercial buildings, dedicated, express elevator services are required for specific VIP passengers. Typically, these buildings utilize multiple elevators grouped together to provide transportation services, improving overall transportation efficiency. When a group control system detects a VIP passenger requesting service through a VIP-specific call device, the following common approaches are currently in place:

[0003] VIP service elevators are group-controlled, designated elevators that no longer respond to landing calls and cannot register new car calls. They must complete existing car calls before proceeding to the VIP floor to serve VIP passengers. This method can easily lead to long wait times for VIP passengers during rush hour and lunchtime.

[0004] VIP service elevators are group-controlled, dedicated elevators. When dispatching elevators, the group control system reduces the weight of designated elevators serving ordinary calls, prioritizing ordinary calls to non-designated elevators. This makes it difficult for designated elevators to serve ordinary calls. This reduces the waiting time for designated VIP passengers when a designated call is in place. However, this approach reduces group elevator transportation efficiency when there are no designated VIP passenger calls.

[0005] VIP service elevators are any elevator in a group control system. The group control system calculates the service time required for each elevator in the group to complete a car call and selects the elevator with the shortest service time to serve the VIP passenger. This method not only fails to effectively solve the problem of long wait times for VIP passengers during rush hour and lunchtime, but also makes it difficult for VIP passengers to determine which elevator in the group is serving 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 scheduling system and scheduling 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, which is responsible for dispatching and allocating elevator groups;

[0011] Elevator controller, which is responsible for 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. The common call registration device is connected to the elevator controller and transmits the floor call information to the elevator controller. The elevator controller is connected to the group control dispatcher and transmits the floor call information to the group control dispatcher.

[0013] VIP call registration device, which is only installed 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 and transmit the VIP passenger call information to the group control dispatcher through the elevator controller;

[0014] A car call registration device is installed in each elevator car in the group. 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 will add the transfer stop floor and transfer elevator information.

[0016] Furthermore, the group control scheduler includes:

[0017] Communication unit: The communication unit is used to receive the elevator controller's transmission of the general landing call information, VIP landing call information and car call information;

[0018] VIP passenger registration table, which is used to store preset waiting time values ​​for 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 different levels of VIP passengers and the busyness of group-controlled elevators;

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

[0021] The dispatching and allocation department compares the VIP passenger estimated waiting time and the VIP passenger waiting time value, reallocates the VIP elevator's car call 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 includes the following steps:

[0026] S1: A VIP passenger registers a VIP call on a VIP call registration device, and the VIP call registration device transmits the VIP call registration signal to the group control dispatcher via the VIP elevator controller;

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

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

[0029] S2-3: If the VIP passenger's estimated waiting time is greater than the VIP waiting time value, the group control dispatcher will allocate 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 VIP passenger's estimated waiting time until the VIP passenger's estimated waiting time 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 scheduling transfer information through text, graphics, voice, etc. through the VIP car prompt device to transfer to other elevators in the group. The VIP elevator will no longer respond to ordinary landing calls. After the ordinary passenger leaves 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 for VIP passengers can be less than or equal to the VIP waiting time value. The group control dispatcher will instruct the VIP elevator to stop at the nearest floor and open the door. After the ordinary passengers leave the car, the door will be closed and the elevator will go directly to the VIP service floor to ensure that the VIP elevator can provide VIP service in the shortest time.

[0031] S2-4: If the estimated waiting time for a VIP passenger is less than the VIP waiting time value, the VIP elevator will no longer respond to ordinary landing calls. After serving all ordinary car calls, it will go to the VIP service floor 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 assigned to the VIP elevator's ordinary car call to go to the VIP elevator transfer landing. After arriving, they open the doors 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 landing call, the group control dispatcher will reallocate the ordinary landing call assigned to the VIP elevator to other elevators in the group, and deploy the VIP elevator to go directly to the VIP service floor, and will no longer respond to ordinary landing 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 utilization efficiency of the group elevators.

[0042] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figure 1-5 As shown, an elevator operation scheduling system includes:

[0045] Group control dispatcher, which is responsible for dispatching and allocating elevator groups;

[0046] Elevator controller, which is responsible for elevator operation control;

[0047] Common call registration device: Each elevator in the group is equipped with a common call registration device at the service floor. The common call registration device is connected to the elevator controller and transmits the floor call information to the elevator controller. The elevator controller is connected to the group control dispatcher and transmits the floor call information to the group control dispatcher.

[0048] VIP call registration device, which is only installed 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;

[0049] A car call registration device is installed in each elevator car in the group. The car call registration device transmits the car call information to the group control dispatcher through the elevator controller;

[0050] 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 will add the transfer stop floor and transfer elevator information.

[0051] Specifically, such as Figure 2 As shown, the group control scheduler includes:

[0052] Communication unit: The communication unit is used to receive the elevator controller's transmission of the general landing call information, VIP landing call information and car call information;

[0053] VIP passenger registration table, which is used to store preset waiting time values ​​for VIP passengers of different levels;

[0054] VIP passenger waiting time calculation unit, which is used to calculate the VIP passenger waiting time value according to different levels of VIP passengers and the busyness of group-controlled elevators;

[0055] VIP Passenger Estimated Waiting Time Assessment Department: The VIP Passenger Estimated Waiting Time Assessment Department assesses the time required for the VIP elevator to reach the VIP call floor after serving all ordinary car calls, which is the VIP passenger estimated waiting time;

[0056] The dispatching and allocation department compares the VIP passenger estimated waiting time and the VIP passenger waiting time value, reallocates the VIP elevator's car call to other elevators in the group, and outputs the allocation result to the elevator controller.

[0057] Specifically, such as Figure 3 As shown, the VIP passenger registration table records VIP passengers of different levels. 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.

[0058] Specifically, 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.

[0059] Specifically, 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.

[0060] A scheduling method for an elevator operation scheduling system, such as Figure 5 As shown, the following steps are included:

[0061] S1: A VIP passenger registers a VIP call on a VIP call registration device, and the VIP call registration device transmits the VIP call registration signal to the group control dispatcher via the VIP elevator controller;

[0062] S2-1: If the VIP elevator has been assigned a normal landing call, the VIP elevator will no longer respond to the normal landing call, and the group control dispatcher will reallocate the normal landing call of the VIP elevator to other elevators in the group;

[0063] S2-2: If the VIP elevator has registered a normal car call, the group control dispatcher estimates the time required for the VIP elevator to reach the VIP call floor after serving all normal car calls based on the VIP elevator's running direction and car call distribution, i.e. the estimated waiting time for the VIP passenger.

[0064] S2-3: If the VIP passenger's estimated waiting time is greater than the VIP waiting time value, the group control dispatcher will dispatch the farthest ordinary car calls to other suitable elevators in the group along the direction of elevator operation, and re-evaluate the VIP passenger's estimated waiting time until the VIP passenger's estimated waiting time 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 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 landing calls. After ordinary passengers leave the car, the door closes and the elevator goes 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 for VIP passengers can be less than or equal to the VIP waiting time value. The group control dispatcher will instruct the VIP elevator to stop at the nearest floor and open the door. After the ordinary passengers leave the car, the door will be closed and the elevator will go directly to the VIP service floor to ensure that the VIP elevator can provide VIP service in the shortest time.

[0066] S2-4: If the estimated waiting time for a VIP passenger is less than the VIP waiting time value, the VIP elevator will no longer respond to ordinary landing calls. After serving all ordinary car calls, it will go to the VIP service floor 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 assigned to the VIP elevator's ordinary car call to go to the VIP elevator transfer landing. After arriving, they open the doors 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 landing call, the group control dispatcher will reallocate the ordinary landing call assigned to the VIP elevator to other elevators in the group, and deploy the VIP elevator to go directly to the VIP service floor, and will no longer respond to ordinary landing 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 utilization efficiency of the group elevators.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
