Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, there is shown a flow chart of the steps of a method of controlling an elevator group, which may include a plurality of elevators, according to an embodiment of the present invention; specifically, the method can comprise the following steps:
step 101, when a target call signal is received, determining at least one target ladder dispatching cost of each elevator responding to the target call signal.
Wherein, each elevator in the elevator group can be controlled by a PLC (Programmable Controller); as shown in fig. 2, the plc controller may be connected to an upper system through an industrial ethernet so as to perform updating, calibration, and the like based on data transmitted from the upper system. The host system may be a device with computing power and generating control instructions, such as: an industrial computer. The PLC controller can be connected to the elevators in the elevator group (e.g., elevator No. 1, elevator No. 2, elevator No. 3, … …, etc.).
When a user wants to take the elevator to a target floor, the user operation can be executed aiming at an outbound button of the elevator; in response to the user operation, the PLC controller may generate a target call signal and determine at least one target dispatch cost that any elevator would generate if responding to the target call signal; the target ladder assignment cost may be, for example: the embodiment of the present invention does not limit the time cost that the user needs to wait, the time cost that the user needs to take the elevator to reach the target floor from the elevator, the energy consumption cost that the elevator needs to consume for operation, and the like.
And 102, determining target weight information of each target ladder dispatching cost according to the current running state of the elevator group.
After the target ladder dispatching cost of each elevator responding to the target call signal is determined, target weight information aiming at the target ladder dispatching cost can be determined according to the current running state of an elevator group; specifically, whether the elevator in the elevator group is currently in an idle state or a busy state can be determined according to the current running state.
As an example, when it is determined that the elevator group is in an idle state according to the current operation state, it may indicate that fewer people are riding the elevator at this time; therefore, energy saving can be taken as a key point; at this time, the weight for energy consumption may be set to be larger, and the weight for the other may be set to be larger; so as to reduce the waste of energy consumption caused by dispatching the elevator in the process of dispatching the elevator aiming at the target call signal.
As another example, when it is determined that the elevator group is in a busy state according to the current operation state, it may indicate that more people are riding the elevator at this time; therefore, efficiency can be taken as a focus; in this case, the weight for efficiency (e.g., boarding time, waiting time, etc.) may be set to be larger, and the other weights may be set to be smaller; in the process of dispatching the elevator aiming at the target call signal, the elevator waiting/taking time of the user is reduced, so that the transportation efficiency of the elevator group is improved.
It should be noted that: the relationship between the operating state and the weight information may be set according to an actual situation, and this is not particularly limited in the embodiment of the present invention.
And 103, determining the target ladder dispatching cost of each elevator responding to the target call signal according to the at least one target ladder dispatching cost and the target weight information.
After the target ladder dispatching cost of each elevator for the target call signal and the target weight information of the current target ladder dispatching cost are determined, the total ladder dispatching cost, namely the target ladder dispatching cost, which is generated if any elevator responds to the target call signal, can be calculated according to at least one target ladder dispatching cost and the target weight information.
And step 104, taking the elevator corresponding to the target elevator dispatching cost with the minimum numerical value as a target elevator, and controlling the target elevator according to the target call signal.
After the target elevator dispatching cost corresponding to each elevator is determined, one elevator corresponding to the target elevator dispatching cost with the minimum numerical value can be used as the target elevator.
After the target elevator is determined, the target elevator can be controlled according to the target call signal; specifically, the target elevator can be controlled to run to the floor corresponding to the target call signal, so that the user can take the target elevator to reach the target floor.
It should be noted that, when the control target elevator moves to the floor corresponding to the target call signal, the control target elevator needs to complete the received call signal to be processed first. For example: the target elevator is currently at 9 floors, and the floor corresponding to the target call signal is 1 floor; if the target elevator needs to stop at 5 floors and 6 floors, the PLC controller may control the target elevator to move from 9 floors to 6 floors, then move from 6 floors to 5 floors, and then control the target elevator to move to 1 floor.
In the embodiment of the invention, when a target call signal is received, at least one target ladder dispatching cost of each elevator responding to the target call signal can be determined; then determining target weight information of each target ladder dispatching cost according to the current running state of the elevator group, and determining the target ladder dispatching cost of each elevator responding to the target call signal according to at least one target ladder dispatching cost and the target weight information; and then, the elevator corresponding to the target elevator dispatching cost with the minimum numerical value is used as a target elevator, and the target elevator is controlled according to the target call signal. According to the embodiment of the invention, the cost of different elevators responding to the target call signal is determined based on the current state of the elevator group, and the elevator with the minimum cost is taken as the target elevator to be dispatched to the user, so that reasonable elevator dispatching of the elevator group is realized, and the user experience and the energy saving of the elevator are considered.
Referring to fig. 3, a flow chart showing the steps of a control method of an elevator group according to an embodiment of the present invention may include the steps of:
and 301, determining the current control parameters aiming at the elevator group at the current time when the target call signal is received.
Wherein the current control parameter may be indicative of an electrical parameter of the motor in the elevator group, such as: rated power, rated voltage, rated current, rotational speed, etc., which are not limited in this embodiment of the present invention.
In practical application, the elevator group can be controlled in a dynamic strategy mode; specifically, different strategies can be set according to the running states of the elevator group at different times, and different control parameters can be correspondingly set. The control parameters can be used to ensure that the elevator group can complete the corresponding optimization objective in an operating state, and the optimization objective can be, for example: energy consumption, efficiency, etc.
When the elevator group is under different control parameters, the running speed, the door opening and closing speed and the like of the elevator group are different; it is thus possible, when a target call signal is received, to determine the current control parameters set for the elevator group at the current time and, on the basis of the current control parameters, to determine the costs that any one of the elevators would have incurred if it responded to the target call signal.
In an embodiment of the invention, the current control parameter may be determined by the following sub-steps:
and a substep 11 of determining a target time interval to which the current time belongs.
First, the current time when the target call signal is received may be determined; then, a target time interval to which the current time belongs may be determined. The time interval may be divided, for example: the time of day may be divided into: 07-00, 10: 00-17.
And a substep 12 of determining a current control parameter corresponding to the target time interval from the corresponding relationship between the preset time interval and the control parameter.
In practical application, the corresponding relation between the time interval and the control parameter can be preset; then, after the target time is determined, the current control parameter corresponding to the target event interval to which the current time belongs may be determined from the correspondence.
In an embodiment of the present invention, the method may further include the following steps:
and controlling the operation of the elevator group by adopting the current control parameters.
In practical application, different control parameters can be adopted to control the elevators in the elevator group at different times; for example: the motors in the elevator group can be controlled at different times and with different powers and different rotational speeds so that the motors operate at different times and with different powers, different rotational speeds, etc.
At the same time, the currently remaining call signals to be processed of each elevator, as well as the floor at which it is currently located, can be determined separately.
And step 303, calculating the target elevator waiting time, the target elevator taking time and the target energy consumption of an elevator responding to the target call signal according to the current control parameter, the call signal to be processed and the current floor respectively, wherein the target elevator dispatching cost comprises the target elevator waiting time, the target elevator taking time and the target energy consumption.
The target elevator waiting time can comprise the time that all users need to wait for one elevator and the time that the user corresponding to the target call signal needs to wait for one elevator when the user takes the elevator; the time to wait for the elevator may refer to the time it takes for the elevator to reach the floor where the user is currently located since the user pressed the outbound button.
The target elevator taking time can comprise the time required by all users to take the elevator for one elevator and the elevator taking time required by the user corresponding to the target call signal to take the elevator to reach the target floor; the boarding time may refer to the time it takes for a user from entering the elevator to the time the elevator reaches the target floor corresponding to the target call signal.
The target energy consumption can comprise the energy consumption required for conveying the users who take the elevator and are about to take the elevator to the corresponding target floor and the energy consumption required for conveying the users corresponding to the target call signals to the corresponding target floor for one elevator; the energy consumption can be related to the door opening and closing times of the elevator, the up-down speed of the elevator and the load of the elevator.
After the current control parameters, the call signal to be processed of the elevator and the current floor are determined, the target elevator waiting time, the target elevator taking time and the target energy consumption can be respectively calculated according to the current control parameters, the call signal to be processed and the current floor.
As an example, the target elevator waiting time can be estimated according to the speed of the elevator, the door opening and closing time, the number of passengers getting in and out, the state of an internal command signal (the internal command means that the elevator is already in the elevator dispatching process and can be prepared for next elevator dispatching after the elevator dispatching operation is completed), and an allocated call signal; specifically, the up-down speed and the door opening and closing speed of an elevator can be determined according to the current control parameters; determining the number of times of the elevator to stop according to the call signal to be processed and the current floor; determining whether the elevator can be dispatched only when the current elevator dispatching task is finished according to the state of the internal command signal; then, the target waiting time is calculated based on the up-down speed, the door opening and closing speed, the floor difference, the number of times of coming to stop, the state of the internal command signal, and the like.
For example: the target waiting time generated by elevator k in response to all the allocated N call signals (including the allocated and target call signals) is
As another example, the target ride time may also be pre-estimated based on the speed of the elevator, the door opening and closing time, the number of passengers entering and exiting, the status of the internal command signal, and the assigned call signal; specifically, the up-down speed and the door opening and closing speed of an elevator can be determined according to the current control parameters; determining the number of times of stopping the elevator after the elevator reaches a target floor according to the call signal to be processed; determining whether the elevator can be dispatched only when the current elevator dispatching task is finished according to the state of the internal command signal; then, the target boarding time is calculated based on the up-down speed, the door opening and closing speed, the floor difference, the number of times of parking is required, the state of the internal command signal, and the like.
For example: elevator k responds to all allocated N callsThe target landing time generated by the call signal (including the allocated and target call signal) is
As yet another example, the target energy consumption may be determined according to the number of users riding the elevator, the number of stops, the floor difference, and the like; specifically, the target energy consumption may be calculated according to the operating power of the motor, the number of stops, the floor difference, and the like.
For example: the target energy consumption generated by elevator k in response to all allocated N call signals (including allocated and target call signals) is
And 304, determining a target control strategy corresponding to the current control parameter, and determining a target weight interval corresponding to the target control strategy.
In practical applications, various control strategies may be preset, for example: under the condition of up-peak traffic, the elevator operation is preferably managed by adopting a dynamic partitioning strategy so as to achieve higher transportation efficiency; in balanced inter-layer traffic, a multi-objective optimization strategy may be employed to achieve performance optimization for multiple service objectives. When the traffic is in an idle state (non-working time), partial elevators can be used for being stopped, so that the aim of energy conservation is fulfilled.
For different control strategies, different control parameters may be set so as to achieve the purpose that the corresponding control strategy is expected to achieve, for example: if the dynamic partitioning strategy is expected to have higher transportation efficiency, control parameters capable of running at a higher speed can be set; if the multi-objective optimization strategy is expected to take efficiency and energy consumption into consideration, part of elevators can be stopped or control parameters of normal running speed can be set, and the embodiment of the invention is not limited to this.
However, there is also randomness in the use of the elevator group, namely: only a few people need to take the elevator in a certain time period of the peak period of work; or, in an idle state, a large number of people suddenly need to go to each floor; therefore, a weight interval can be set for different control strategies, so that the weights corresponding to different ladder dispatching costs can be adjusted at any time in emergency, and ladder dispatching can be reasonably performed in emergency.
Specifically, after the target control strategy is determined, a target weight interval preset for the target control strategy may be determined; the target weight interval may include sub-intervals set for different derived ladder costs, such as: the embodiment of the present invention does not limit the subinterval set for the waiting time, the subinterval set for the boarding time, and the subinterval set for the energy consumption.
And 305, determining target weight information of each target ladder dispatching cost from the target weight interval according to the current operation state.
After the target weight interval is determined, target weight information of ladder assignment costs for each target can be determined from the target weight interval by combining the current operation state of the elevator group. Specifically, whether energy consumption saving is required to be used as the purpose or transportation efficiency is required to be improved is determined according to the current running state of the elevator group; and then, according to the determined purpose, determining target weight information of each target ladder dispatching cost from the target weight interval.
It should be noted that the sum of the target weight information corresponding to all the target ladder assignment costs is equal to 1.
And step 306, determining the target ladder dispatching cost of each elevator responding to the target call signal according to the at least one target ladder dispatching cost and the target weight information.
After determining the target ladder dispatching cost of each elevator for the target call signal and the target weight information of the current target ladder dispatching cost, calculating the total ladder dispatching cost, namely the target ladder dispatching cost, which is generated by any elevator if responding to the target call signal, according to at least one target ladder dispatching cost and the target weight information.
For example: target ladder-dispatching cost F (k):
wherein, ω is 1 、ω 2 、ω 3 Is target weight information;
After optimizing according to the formula:
S＝w 1 ·awt+w 2 .art+w 3 .crd；
wherein, w 1 、w 2 、w 3 Is target weight information;
awt is the target waiting time;
art is the target elevator taking time;
crd is the degree of customer congestion, which corresponds to energy consumption; for example: when the customer crowding degree is high, the energy consumption is large, and when the customer user degree is low, the energy consumption is small; the degree of customer congestion may also be determined by a camera device deployed within the elevator car;
and S is the target ladder dispatching cost.
And 307, taking the elevator corresponding to the target elevator dispatching cost with the minimum numerical value as a target elevator, and controlling the target elevator according to the target call signal.
After the target elevator dispatching cost corresponding to each elevator is determined, one elevator corresponding to the target elevator dispatching cost with the minimum numerical value can be used as the target elevator.
After the target elevator is determined, the target elevator can be controlled according to the target call signal; specifically, the target elevator can be controlled to run to the floor corresponding to the target call signal, so that the user can take the target elevator to reach the target floor.
As an example, corresponding travel zones may be set in advance for different elevators; namely: floors mainly targeted, for example: the No. 1 elevator mainly moves from the floor 1 to the floor 10, and the No. 2 elevator mainly moves from the floor 11 to the floor 20; when determining the target elevator, the operation area corresponding to the elevator may be comprehensively considered, and the elevator corresponding to the operation area is preferentially selected, which is not limited in the embodiment of the present invention.
Fig. 4 shows a schematic flow chart of dispatching a ladder according to an embodiment of the present invention:
as an example, when a destination call signal is received, it is first determined whether the starting floor corresponding to the destination call signal is higher than the floor where an elevator is currently located.
If the initial floor is higher than the current floor of the elevator, judging whether the running direction of the elevator is the same as the direction of the target call signal; for example: the running direction of the elevator is from top to bottom, and the target call signal is from bottom to top, so that the running direction of the elevator and the target call signal can be judged to be different.
If the running direction of the elevator is the same as the direction of the target call signal, the elevator can be controlled to respond to the target call signal; if the running direction of the elevator is not the same as the direction of the target call signal, whether other descending call signals exist below the elevator is judged.
If there is other downlink calling signal under it, then waiting to process the other downlink calling signal, and then processing the target calling signal; the elevator can be controlled directly to respond to the target call signal if there are no other downstream call signals below.
As another example, when a destination call signal is received, it is first determined whether the starting floor to which the destination call signal corresponds is lower than the floor at which an elevator is currently located.
If the starting floor is lower than the floor where the elevator is located at present, whether the running direction of the elevator is the same as the direction of the target call signal is judged.
If the running direction of the elevator is the same as the direction of the target call signal, the elevator can be controlled to respond to the target call signal; if the running direction of the elevator is different from the direction of the target call signal, whether other uplink call signals exist above the elevator or not is judged.
If there is other ascending calling signal above, then waiting to process other ascending calling signal, and then processing target calling signal; the elevator can be controlled directly to respond to the target call signal if there are no other call signals going upwards.
Of course, if it is determined that the starting floor corresponding to the target call signal is not higher than the floor at which an elevator is currently located, the step of determining whether the starting floor corresponding to the target call signal is lower than the floor at which an elevator is currently located may be performed; or, if it is determined that the starting floor corresponding to the target call signal is not lower than the floor where an elevator is currently located, the step of determining whether the starting floor corresponding to the target call signal is higher than the floor where an elevator is currently located may be performed.
When the elevator responds to the target call signal and reaches the initial layer corresponding to the target call signal, the door of the elevator car can be opened, and after the preset time and when no object is detected between the door gaps, the door of the elevator car is closed; and then, the operation is carried out to a target layer corresponding to the target calling signal.
In an embodiment of the present invention, in order to shorten the elevator taking time and the elevator waiting time of the user, the embodiment of the present invention may further include the following steps:
determining the current load of an elevator; the running speed of an elevator is adjusted according to the current load of the elevator.
In practical applications, the electric machines in the elevator group may be ac motor systems; when the elevators in the elevator group go up and down, the current load of one elevator can be determined; the current load can be obtained from a weight detection sensor arranged under the elevator; of course, the image data may be obtained from an image capturing device disposed in the elevator car and determined based on the image data, which is not limited in the embodiment of the present invention.
After the current load is determined, an adjustment instruction can be sent to an alternating current motor system of a motor corresponding to the elevator according to the current load, and the running speed of the elevator is changed through a voltage and speed regulating system in the alternating current motor system; for example: when the current load of the elevator is smaller than the weight threshold value, the running speed of the elevator can be increased so as to shorten the time for a user to take the elevator and wait for the elevator; when the current load of the elevator is greater than the weight threshold, the elevator can be operated at a normal speed in order to ensure the safety of the user in the elevator car.
In an embodiment of the present invention, the elevator riding experience of the user can be ensured by the following steps:
determining whether a first distance between the current height of the elevator and the height of a target floor corresponding to a call signal responded by the elevator is greater than a first distance threshold value; and when the distance is larger than the first distance threshold value, executing a step of adjusting the running speed of an elevator according to the current load of the elevator.
Firstly, the current height of the elevator and the height of a target floor corresponding to a call signal currently responded by the elevator can be determined; then, a first distance between the current height of the elevator and the height of the destination floor corresponding to the call signal to which the elevator is currently responding is determined.
After determining the first distance, a relationship between the first distance and a first distance threshold may be compared; if the first distance is less than the first distance threshold, it may indicate that the elevator is about to reach the target floor to which the currently responded call signal corresponds.
In this case, in order to avoid poor experience of the user in riding the elevator due to frequent acceleration and deceleration, the elevator can be continuously operated at a normal speed without changing the operation speed of the elevator.
When the first distance is greater than the first distance threshold, the elevator can be indicated to be farther away from the target floor corresponding to the current response call signal; at this time, in order to shorten the boarding time of the user, a step of adjusting the operation speed of an elevator according to the current load of the elevator may be performed so as to increase the operation speed of the elevator, thereby shortening the boarding time of the user.
In practical application, when an elevator reaches a target floor, the elevator may suddenly decelerate, so that a user may be difficult to stably stand due to no preparation, and the elevator riding experience of the user is influenced; therefore, in combination with the above-mentioned ac motor system, the embodiments of the present invention may further perform the following steps:
when the first distance between the current height of an elevator and the height of a target floor corresponding to a call signal responded by the elevator is smaller than a second distance threshold value, a preset pulse signal is sent to a motor corresponding to the elevator.
After the first distance is determined, the relationship between the first distance and a second distance threshold value can be compared, and the second distance threshold value can be used for judging whether the elevator is about to reach a target floor corresponding to the current responded call signal; when the first distance is less than the second distance threshold, it may indicate that the elevator is about to reach the target floor corresponding to the currently responded call signal; at the moment, a preset pulse signal can be sent to a motor corresponding to the elevator so as to achieve the effect of stable stop of the target floor.
When the first distance is not less than the second distance threshold, the elevator can be represented that the elevator does not reach the target floor corresponding to the current corresponding call signal; at this time, normal operation of the elevator may be continuously ensured, or the operation speed of the elevator may be increased, etc., which is not limited in the embodiment of the present invention.
As an example, the altitude may be measured by a rotary encoder measuring the rotational speed and then determining the altitude from the rotational speed and the time that has been rotated; the height of the destination floor to which the call signal is responded can be determined by the floor height collected in advance.
It should be noted that when dispatching elevators, the basic rules of elevator operation need to be observed, for example: an internal instruction rule, a steering rule, and a full load rule.
The internal command rule can mean that no matter what state the elevator is in, the internal command signal in the running direction of the elevator must be responded, and the internal command signal which is not in the current running direction is not responded.
The diversion rules may mean that the elevator is not diverted before all the passengers in the car have reached the destination floor.
The full load rule may mean that when the number of car passengers reaches the nominal number of passengers, no further call signals are responded to.
As an example, when an elevator in an elevator group is initialized, other elevators in the elevator group will also be initialized, e.g.: all default states of the elevator, such as arrival at a stop, congestion level, elevator riding time, etc., are cancelled.
In one embodiment of the present invention, when the car door of the elevator is to be opened or closed, an alarm prompt may be made, such as: and sending out a safety early warning light beam to remind a user that the elevator car door of the elevator is about to be opened or closed.
In the embodiment of the invention, when a target call signal is received, the current control parameters aiming at an elevator group at the current time are firstly determined; determining a call signal to be processed and a current floor for an elevator; the target ladder dispatching cost comprises target ladder waiting time, target ladder taking time and target energy consumption, and the target ladder waiting time, the target ladder taking time and the target energy consumption of an elevator responding to the target calling signal are respectively calculated according to the current control parameters, the call signal to be processed and the current floor; determining a target control strategy corresponding to the current control parameter, and determining a target weight interval corresponding to the target control strategy; determining target weight information of ladder dispatching cost of each target from the target weight interval according to the current operation state; determining the target ladder dispatching cost of each elevator responding to the target call signal according to at least one target ladder dispatching cost and the target weight information; and taking the elevator corresponding to the target elevator dispatching cost with the minimum value as a target elevator, and controlling the target elevator according to the target call signal. Through the embodiment of the invention, the cost of waiting time, taking time, target energy consumption and the like of different elevators responding to the target call signal is determined based on the current state of the elevator group, and the elevator with the minimum cost is taken as the target elevator to be dispatched to the user, so that reasonable elevator dispatching of the elevator group is realized, and the user experience and the energy saving of the elevator are considered.
And in the up-and-down running process of the elevator, the running speed of the elevator is adjusted according to the current load of the elevator, so that the running safety of the elevator is ensured, and the transportation efficiency of the elevator is improved.
