Description

Technical Field

[0001] The present invention relates to an elevator control system. Background Art

[0002] In order to improve the operating efficiency of elevators, in buildings equipped with multiple elevators, a group management system is usually adopted to uniformly allocate multiple elevators, so as to efficiently respond to the elevator call signals of passengers and transport passengers. However, in engineering practice, due to reasons such as original design or later elevator renovation, there are often multiple elevators in a common waiting hall that are under the group control of different elevator group control systems, and the elevators under the group control of different elevator group control systems are equipped with different landing registration devices and landing display devices. Such a setting makes it that when passengers on the same floor want to board the elevator faster, they often use each landing registration device to register elevator call signals for multiple elevator group control systems at the same time. As a result, multiple elevator group control systems will each dispatch an elevator to respond to the call signal. Passengers usually board the first-arriving elevator and leave the floor, which will cause the later-arriving elevator to make an ineffective stop on this floor, thus seriously affecting the operating efficiency of this elevator.

[0003] In response to this problem, Document 1 (Chinese Patent Application No.: CN202210009759.0) proposes a group control scheduling system for elevators of different brands, including an elevator group control processor, an original elevator controller, at least one new elevator controller, at least one elevator car of the original brand associated with the original elevator controller, and at least one elevator car of the new brand associated with each new elevator controller; the elevator group control processor includes an elevator group controller; the elevator group control processor is configured to, when receiving a boarding request from a passenger, send the boarding request to the elevator group controller; the elevator group controller is configured to, according to the received boarding request, perform group control scheduling on all elevator cars to determine a target elevator controller from all elevator controllers; generate a car dispatching control instruction according to the boarding request, and send the car dispatching control instruction to the target elevator controller; the elevator controller is the original elevator controller or the new elevator controller; the target elevator controller is configured to obtain the boarding task corresponding to the boarding request according to the received car dispatching control instruction, determine a target elevator car among the associated elevator cars, and control the target elevator car to respond to the boarding task. This solution essentially uses the elevator group controller to uniformly perform group control scheduling on all elevators including the original elevator and the new elevator, and determines one of them as the target elevator according to the group control scheduling.

[0004] Reference 1 overcomes the problem of low operating efficiency of multiple elevators under the group control of different group control systems by uniformly group-controlling and scheduling all elevators, including the original elevators and the newly added elevators. However, since the unified group control scheduling and control are implemented by the elevator group controller, the group controllers of the original elevators and the newly added elevators become ineffective, resulting in the abandonment of the group controllers of the elevators and the newly added elevators. On the other hand, since the elevator group controller needs to complete the unified group control scheduling and control of all elevators, including the original elevators and the newly added elevators, the group control calculation load to be completed is extremely large, thus forming a high demand for the calculation and processing ability of the elevator group controller, which means high cost. Therefore, in fact, Reference 1 wastes the calculation and processing ability by abandoning the group controllers of the original elevators and the newly added elevators, and on the other hand, it creates a high demand for the calculation and processing ability of the elevator group controller. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to make full use of the calculation and processing capabilities of all group controllers to achieve unified group control scheduling and control of elevators in multiple group control systems at low cost.

[0006] To solve the above technical problem, the present invention provides an elevator control system, including a group manager, a first group controller, and a second group controller;

[0007] The first group controller controls the first floor registration device, the first floor display device, and the single elevator controller of each elevator in the first elevator group; the second group controller controls the second floor registration device, the second floor display device, and the single elevator controller of each elevator in the second elevator group;

[0008] The group manager, the first group controller, and the second group controller cooperate to control the call signals sent by passengers, so that only one elevator in the first elevator group and the second elevator group responds to the call signal.

[0009] Preferably, the method for the group manager, the first group controller, and the second group controller to cooperate to control the call signals sent by passengers is as follows:

[0010] Step A1, when the first floor registration device receives the call signal sent by the passenger, upload the call signal to the first group controller;

[0015] Step A6, the group manager issues a first instruction to the group controller with the optimal index, enabling the group controller with the optimal index to perform elevator allocation for the call signal; the group controller with the optimal index refers to the group controller corresponding to the optimal index among the first group controller and the second group controller;

[0016] Step A7, the group controller with the optimal index determines the target elevator and sends a second instruction to the single elevator controller of the target elevator, enabling the target elevator to respond to the call signal.

[0017] Preferably, in step A7, the group controller with the optimal index controls the floor station display device at the floor where the call signal is issued to light up the call signal indicator lamp until the target elevator arrives at the floor where the call signal is issued.

[0018] Preferably, in step A7, the group controller with the optimal index controls the floor station registration device at the floor where the call signal is issued to be in a non-registrable state until the target elevator arrives at the floor where the call signal is issued.

[0019] Preferably, in step A6, the group manager issues a third instruction to other group controllers except the group controller with the optimal index, enabling other group controllers to control the floor station display device at the floor where the call signal is issued to light up the call signal indicator lamp until the target elevator arrives at the floor where the call signal is issued.

[0020] Preferably, the third instruction also enables other group controllers to control the floor station registration device at the floor where the call signal is issued to be in a non-registrable state until the target elevator arrives at the floor where the call signal is issued.

[0021] Preferably, other group controllers turn off the call signal indicator lamp after the target elevator arrives at the floor where the call signal is issued. The method of turning off the call signal indicator lamp is as follows: after the target elevator arrives at the floor where the call signal is issued, the group controller with the optimal index sends a signal to turn off the lamp to the group manager; the group manager sends the signal to turn off the lamp to other group controllers; other group controllers control the floor station display device at the floor where the call signal is issued to turn off the call signal indicator lamp.

[0022] Preferably, after the target elevator arrives at the floor where the call signal is issued, other group controllers cause the landing registration device on the floor where the call signal is issued to resume the registrable state. The method for resuming the registrable state is as follows: after the target elevator arrives at the floor where the call signal is issued, the optimal index group controller sends a resume registration signal to the group manager; the group manager sends the resume registration signal to other group controllers; and other group controllers control the landing registration device on the floor where the call signal is issued to resume the registrable state.

[0029] Step B6, the group manager distributes the third target elevator to the group controller to which the third target elevator belongs;

[0030] Step B7, the group controller to which the third target elevator belongs sends a second instruction to the single elevator controller of the third target elevator so that the third target elevator responds to the call signal.

[0031] Preferably, in step B7, the group controller to which the third target elevator belongs controls the landing display device on the floor where the call signal is issued to light up the call signal indicator light until the target elevator arrives at the floor where the call signal is issued.

[0032] Preferably, in step B7, the group controller to which the third target elevator belongs controls the landing registration device on the floor where the call signal is issued to be in a non-registrable state until the target elevator arrives at the floor where the call signal is issued.

[0033] Preferably, in step B6, the group manager sends a third instruction to other group controllers except the group controller to which the third target elevator belongs, so that the other group controllers control the landing display device on the floor where the call signal is sent to turn on the call signal indicator light until the target elevator arrives at the floor where the call signal is sent.

[0034] Preferably, the third instruction also makes the other group controllers control the landing registration device on the floor where the call signal is sent to be in a non-registrable state until the target elevator arrives at the floor where the call signal is sent.

[0035] Preferably, after the target elevator arrives at the floor where the call signal is sent, the other group controllers turn off the call signal indicator light. The method for turning off the call signal indicator light is as follows: after the target elevator arrives at the floor where the call signal is sent, the group controller to which the third target elevator belongs sends a light-off signal to the group manager; the group manager sends the light-off signal to the other group controllers; the other group controllers control the landing display device on the floor where the call signal is sent to turn off the call signal indicator light.

[0036] Preferably, after the target elevator arrives at the floor where the call signal is sent, the other group controllers make the landing registration device on the floor where the call signal is sent return to the registrable state.

It should be understood that these embodiments are provided to make the disclosure of the present invention complete and thorough, and to fully convey the technical solutions of these exemplary specific embodiments to those skilled in the art.

[0041] Embodiment 1

[0042] As Figure 1 shown, there are a total of 4 elevators installed in the building, and these 4 elevators share the same waiting hall on the same floor. Elevators #1 and #2 form the first elevator group, and the first group controller controls the first floor landing registration device, the first floor landing display device, and the single elevator controllers of each elevator in the first elevator group, that is, Figure 1 the first single elevator controller in Figure 1 . Elevators #3 and #4 form the second elevator group, and the second group controller controls the second floor landing registration device, the second floor landing display device, and the single elevator controllers of each elevator in the second elevator group, that is,

[0043] the second single elevator controller in

[0044] When a passenger operates the first floor landing registration device, a first call signal for the first elevator group is generated. When a passenger operates the second floor landing registration device, a second call signal for the second elevator group is generated. The first call signal (usually through a first single elevator controller in engineering practice) is uploaded to the first elevator group controller, and the second call signal (usually through a second single elevator controller in engineering practice) is uploaded to the second elevator group controller.

[0045] Embodiment 2

[0046] This embodiment elaborates in detail on the working principle of the elevator control system in Embodiment 1.

[0047] In this embodiment, the method for the group manager, the first group controller, and the second group controller to cooperate in controlling the elevator call signal sent by the passenger is as follows:

[0048] Step A1: When the first-floor registration device receives the elevator call signal sent by the passenger, it uploads the call signal to the first group controller.

[0049] Step A2: The first group controller calculates the first evaluation index and uploads the first evaluation index and the call signal to the group manager.

[0050] Step A3: The group manager distributes the call signal to the second group controller.

[0051] Step A4: The second group controller calculates the second evaluation index and uploads the second evaluation index to the group manager.

[0052] Step A5: The group manager compares the first evaluation index and the second evaluation index to determine the optimal index among them.

[0053] Step A6: The group manager sends a first instruction to the group controller with the optimal index, so that the group controller with the optimal index performs elevator allocation for the call signal; the group controller with the optimal index refers to the group controller corresponding to the optimal index among the first group controller and the second group controller.

[0054] Step A7: The group controller with the optimal index determines the target elevator and sends a second instruction to the single elevator controller of the target elevator, so that the target elevator responds to the call signal.

[0055] For example Figure 1 Taking the 4 elevators as an example, when the passenger registers an upward call signal using the first-floor registration device, the upward call signal (after passing through a first single elevator controller) is uploaded to the first elevator group controller, which is Step A1.

[0056] The first elevator group controller selects #1 and #2 as the optional elevators, calculates the first evaluation index using the operation information of #1 and #2 (the first evaluation index is the optimal index among the evaluation indexes corresponding to all the elevators under the control of the first elevator group controller), and uploads it to the group manager; in addition to calculating the first evaluation index, the first elevator group controller also uploads the upward call signal to the group manager; this is Step A2.

[0057] After receiving the upward call signal, the group manager first determines the source of the upward call signal (here it is from the first elevator group controller or the first-floor registration device), and then distributes the upward call signal to other non-source group controllers (here it is the second group controller), which is Step A3.

[0058] Next, the second group of controllers uses #3 and #4 as the optional elevators for the call signals to be assigned, calculates the second evaluation index (which is the optimal index among the evaluation indexes corresponding to all elevators under the control of the second elevator group controller) using the operation information of #3 and #4, and uploads it to the group manager, which is step A4.

[0059] The group manager, upon receiving the first evaluation index from the first elevator group controller and the second evaluation index from the second elevator group controller, first compares all the received evaluation indexes and determines the optimal index among them (here assumed to be the first evaluation index), which is step A5.

[0060] Then, the source of the optimal index (here the first group of controllers) is taken as the optimal index group controller, and finally, the first instruction is sent to the first group of controllers, enabling the optimal index group controller to perform elevator allocation for the call signals, which is step A6.

[0061] After receiving the first instruction, the first group of controllers first determines the first elevator corresponding to the uploaded first evaluation index and takes it as the target elevator, then determines the single elevator controller of the target elevator, and then sends the second instruction to the single elevator controller of the target elevator; the single elevator controller of the target elevator controls elevator #1 to respond to the call signal according to the second instruction, which is step A7.

[0062] In addition, the first group of controllers also controls the first floor station display device to light up the upward call signal indicator light of the first floor station display device and keep it lit, so as to be able to indicate that the upward call signal has been registered. That is, in step A7, the optimal index group controller controls the floor station display device of the floor where the call signal is issued to light up the call signal indicator light until the target elevator arrives at the floor where the call signal is issued.

[0063] In addition, in step A7, the optimal index group controller controls the floor registration device of the floor where the call signal is issued to be in a non - registrable state until the target elevator arrives at the floor where the call signal is issued.

[0064] The group manager also sends the third instruction to the second elevator group controller. After receiving the third instruction, the second elevator group controller lights up the upward call signal indicator light of the second floor station display device and keeps it lit, and at the same time makes the second floor registration state in a non - registrable state until the target elevator responds to the call signal and arrives at and stops at the floor where the passengers are located. That is, in step A6, the group manager sends the third instruction to other group controllers except the optimal index group controller, enabling other group controllers to control the floor station display device of the floor where the call signal is issued to light up the call signal indicator light, and enabling other group controllers to control the floor registration device of the floor where the call signal is issued to be in a non - registrable state until the target elevator arrives at the floor where the call signal is issued.

[0065] After the target elevator arrives at the floor where the call signal is issued, other group controllers turn off the call signal indicator light. The method for turning off the call signal indicator light is as follows: after the target elevator arrives at the floor where the call signal is issued, the optimal index group controller sends a light-off signal to the group manager; the group manager sends the light-off signal to other group controllers; other group controllers control the floor display device at the floor where the call signal is issued to turn off the call signal indicator light.

[0066] After the target elevator arrives at the floor where the call signal is issued, other group controllers make the floor registration device at the floor where the call signal is issued return to the state where it can register. The method for restoring the state where it can register is as follows: after the target elevator arrives at the floor where the call signal is issued, the optimal index group controller sends a restoration registration signal to the group manager; the group manager sends the restoration registration signal to other group controllers; other group controllers control the floor registration device at the floor where the call signal is issued to return to the state where it can register.

[0067] Embodiment 3

[0068] This embodiment details the working principle of the elevator control system in Embodiment 1.

[0069] In this embodiment, the method for the group manager, the first group controller, and the second group controller to jointly control the call signals issued by passengers is as follows:

[0070] Step B1, when the first floor registration device receives the call signal issued by the passenger, it uploads the call signal to the first group controller;

[0071] Step B2, the first group controller determines the first target elevator and uploads the call signal, the first target elevator, and its operation information to the group manager;

[0072] Step B3, the group manager distributes the call signal to the second group controller;

[0073] Step B4, the second group controller determines the second target elevator and uploads the second target elevator and its operation information to the group manager;

[0074] Step B5, the group manager determines the third target elevator according to the first target elevator and its operation information and the second target elevator and its operation information; the third target elevator is one of the first target elevator and the second target elevator;

[0075] Step B6, the group manager distributes the third target elevator to the group controller to which the third target elevator belongs;

[0076] Step B7, the group controller to which the third target elevator belongs sends a second instruction to the single elevator controller of the third target elevator so that the third target elevator responds to the call signal.

[0077] Taking the four elevators in Figure 1 as an example, when a passenger registers an up call signal using the first floor landing registration device, the up call signal (after passing through a first single elevator controller) is uploaded to the first elevator group controller, i.e., step B1.

[0078] The first elevator group controller selects #1 and #2 as optional elevators, performs group control scheduling using the operation information of #1 and #2, obtains the first target elevator (here assumed to be elevator #1), and uploads the first target elevator and its elevator operation information to the group manager; in addition to determining the first target elevator, the first elevator group controller also uploads the up call signal to the group manager; i.e., step B2.

[0079] After receiving the up call signal, the group manager first determines the source of the up call signal (here it comes from the first elevator group controller or the first floor landing registration device), and then sends the up call signal to other non-source group controllers (here it is the second group controller), i.e., step B3.

[0080] Then, the second group controller takes the call signal to be assigned, selects #3 and #4 as optional elevators, performs group control scheduling using the operation information of #3 and #4, obtains the second target elevator (here assumed to be elevator #3), and uploads the second target elevator and its elevator operation information to the group manager, i.e., step B4.

[0081] After receiving the first target elevator and its elevator operation information from the first elevator group controller and the second target elevator and its elevator operation information from the second elevator group controller respectively, the group manager first selects the first target elevator and the second target elevator as optional elevators, performs group control scheduling using their respective elevator operation information, and outputs the third target elevator (here assumed to be elevator #1), i.e., step B5.

[0082] Then it determines the source of the third target elevator (the first group controller), and finally sends the third target elevator to the first group controller which is the third target elevator, i.e., step B6.

[0083] After receiving the third target elevator, the first group controller first determines the single elevator controller of the third target elevator, then sends a second instruction to the single elevator controller of the third target elevator, and the single elevator controller of the target elevator controls elevator #1 to respond to the call signal according to the second instruction, i.e., step B7.

[0084] In addition, in the step B7, the group controller to which the third target elevator belongs controls the landing display device on the floor where the call signal is sent to turn on the call signal indicator light until the target elevator arrives at the floor where the call signal is sent. The group controller to which the third target elevator belongs controls the landing registration device on the floor where the call signal is sent to be in a non-registrable state until the target elevator arrives at the floor where the call signal is sent.

[0085] In the step B6, the group manager issues a third instruction to other group controllers except the group controller to which the third target elevator belongs, so that the other group controllers control the landing display device on the floor where the call signal is sent to turn on the call signal indicator light, and the other group controllers control the landing registration device on the floor where the call signal is sent to be in a non-registrable state until the target elevator arrives at the floor where the call signal is sent.

[0086] After the target elevator arrives at the floor where the call signal is sent, the other group controllers turn off the call signal indicator light. The method for turning off the call signal indicator light is as follows: after the target elevator arrives at the floor where the call signal is sent, the group controller to which the third target elevator belongs sends a light-off signal to the group manager; the group manager sends the light-off signal to the other group controllers; the other group controllers control the landing display device on the floor where the call signal is sent to turn off the call signal indicator light.

[0087] After the target elevator arrives at the floor where the call signal is sent, the other group controllers make the landing registration device on the floor where the call signal is sent return to the registrable state. The method for returning to the registrable state is as follows: after the target elevator arrives at the floor where the call signal is sent, the group controller to which the third target elevator belongs sends a registration restoration signal to the group manager; the group manager sends the registration restoration signal to the other group controllers; the other group controllers control the landing registration device on the floor where the call signal is sent to return to the registrable state.

[0088] The present invention has been described in detail through specific embodiments and examples, but these do not constitute a limitation to the present invention. Without departing from the principle of the present invention, those skilled in the art can also make many modifications and improvements, which should also be regarded as the protection scope of the present invention.
