Description
Technical Field
The invention relates to the technical field of communication, in particular to an elevator dispatching method, an elevator dispatching device, electronic equipment and a storage medium.
Background
In an elevator system, a plurality of elevators is generally included. When the elevator is dispatched, the dispatching is mainly carried out according to the distance between the elevator and a calling floor, the running direction of the elevator, the calling sequence of the elevator and the like, so that the elevator meets the riding requirements of users.
In the existing elevator dispatching method, the aim of improving the operation efficiency is mostly to respond the call demand of an elevator user at the fastest speed, so that the operation efficiency of the elevator is improved as much as possible and the elevator taking demand of the user is met. However, when the elevator dispatching method is used in practice, the load condition of a certain elevator or a plurality of elevators is often serious, so that the aging of components of the elevators is accelerated, the failure rate is improved, the service life of the elevators is influenced, and the use stability of an elevator system is reduced.

In order to solve the above technical problem, an embodiment of the present invention provides an elevator dispatching method, including: obtaining historical load indexes of each elevator in an elevator system; when a call request is received, calculating the response score of each elevator according to the historical load indexes, wherein the response score is negatively correlated with the historical load indexes; the call request is dispatched to the elevator with the highest response score to respond.
An embodiment of the present invention also provides an elevator dispatching device, including: the acquisition module is used for acquiring the historical load index of each elevator in the elevator system; the calculation module is used for calculating the response score of each elevator according to the historical load indexes when a call request is received, wherein the response score is negatively correlated with the historical load indexes; and the first dispatching module is used for dispatching the call request to the elevator with the highest response score to respond.
An embodiment of the present invention also provides an electronic device, including: at least one processor; and a memory communicatively coupled to the at least one processor; wherein the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the above-described elevator dispatching method.
Embodiments of the present invention also provide a computer-readable storage medium storing a computer program, which when executed by a processor implements the elevator dispatching method described above.
Compared with the related art, the call request is dispatched to the elevator with the highest response score to respond by acquiring the historical load index of the elevator and calculating the response score of the elevator according to the historical load index of the elevator. Because the historical load index can reflect the loss condition of the elevator caused by the load, and the response score is negatively related to the historical load index, the call request is dispatched to the elevator with the highest response score to respond, and the elevator with smaller loss caused by the load can be preferentially used, so that the use of each elevator in the elevator system is balanced, and the service life of the elevator and the use stability of the elevator system are improved.
Additionally, the calculating a response score for each elevator from the historical load indicators includes: calculating a response score for each elevator based on the historical load indicators and current status indicators, wherein the current status indicators include at least one of: current registered floor, current elevator position, current car call, and elevator direction of travel. The response score of the elevator is set to be related to the historical load index, and meanwhile, the current state of the elevator is considered, so that the response score of the elevator can be calculated by comprehensively considering factors related to the running efficiency of the elevator besides the historical use condition of the elevator, and the service life of the elevator and the running efficiency of the elevator are considered simultaneously when the elevator is used.
In addition, the method further comprises: and if the historical load index cannot be obtained and when the call request is received and the response scores of two or more elevators are the same, randomly dispatching the call request to one elevator with the same response score. The call requests are randomly dispatched to one of the elevators with the same response score, so that the use losses of the elevators can be more balanced and close, and the service lives of the elevators are prolonged.
In addition, after the obtaining the historical load index of each elevator in the elevator system, the method further comprises the following steps: if the current running state of the elevator system is in an idle state, increasing the weight of the historical load index in the response score calculation; and if the current running state of the elevator system is in a busy state, reducing the weight of the historical load index in the response score calculation. Because more elevators can respond to the call requests when the elevator system is in an idle state, the weight of the historical load indexes in response score calculation is increased, so that the call requests can be dispatched to the elevators with smaller historical load indexes to respond more preferentially, and the riding experience of the elevators cannot be greatly influenced; when the elevator system is busy, if the weight of the historical load index in the response score calculation is higher, the situation that the elevator close to the call floor of the user does not respond can be caused, the riding experience of the elevator is influenced, and the weight of the historical load index in the response score calculation is reduced, so that the operation efficiency of the elevator system can be improved, and the influence on the riding experience of the elevator is avoided.
In addition, the method further comprises: and identifying the current running state of the elevator system according to the current time and/or IO signal input data of the elevator system.
In addition, after the obtaining the historical load index of each elevator in the elevator system, the method further comprises the following steps: obtaining the calling frequency of each floor in the elevator system; and dispatching the idle elevator with the historical load index lower than the first preset threshold value to the floor with the calling frequency higher than the second preset threshold value. Because the probability that the elevator is used by the floor with higher call frequency is higher, the idle elevator with the historical load index lower than the first preset threshold value is dispatched to the floor with the call frequency higher than the second preset threshold value, so that the response score of the elevator with the smaller historical load index is higher when other factors (such as the position of the elevator) are considered, the elevator is used preferentially, and meanwhile, the use condition of the elevator with the larger historical load index is reduced, the use of each elevator in the elevator system is balanced, and the service life of the elevator and the use stability of the elevator system are improved.
In addition, the obtaining of the historical load index of each elevator in the elevator system comprises: and calculating the historical load index of each elevator in the elevator system according to the historical running times, the historical running distance and/or the historical car load of the elevator, wherein the historical load index is positively correlated with the historical running times, the historical running distance and/or the historical car load. The historical load index of the elevator is calculated through the historical running times, the historical running distance and/or the historical car load, so that the historical load index can truly reflect the loss of the elevator caused by use, the response score of the elevator can effectively reflect the historical use condition of the elevator, and finally the use of the elevator is more balanced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to an elevator dispatching method, which comprises the steps of obtaining the historical load index of each elevator in an elevator system; when a call request is received, calculating the response score of each elevator according to the historical load index, wherein the response score is inversely related to the historical load index; the call request is dispatched to the elevator with the highest response score to respond. Because the response score is negatively correlated with the historical load index, the historical load index of the elevator with a high response score is smaller, the call request is dispatched to the elevator with a smaller historical load index for response, and the load of each elevator in the elevator system can be balanced, so that the service life of the elevator and the use stability of the elevator system are improved.
The specific flow of the elevator dispatching method provided by the embodiment of the invention is shown in figure 1, and comprises the following steps:
s101: a historical load indicator for each elevator in an elevator system is obtained.
The historical load index is used to reflect the historical use condition of the elevator, and may be, for example, an index such as a historical number of times of operation, a historical distance of operation, or a historical load weight.
In a specific example, S101 includes: and calculating the historical load index of each elevator in the elevator system according to the historical running times, the historical running distance and/or the historical car load of the elevator, wherein the historical load index is positively correlated with the historical running times, the historical running distance and/or the historical car load. It can be understood that the larger the historical load index, the greater the loss of the elevator due to use; when the historic load index is smaller, the loss of the elevator due to use is smaller.
In acquiring the historical load index, the range of the used historical data may be set according to actual needs, for example, based on historical data of the past week, historical data of the past month, historical data of the past year, or the like. Alternatively, when the historical data is counted to obtain the historical load index, the historical data may be further subdivided, for example, the historical data closer to the current time may be given a higher weight, and the historical data farther from the current time may be given a lower weight. Because the correlation between the historical data far away from the current time and the current use state of the elevator is weaker, the weight of the historical data far away from the current time is set to be lower, and the weight of the historical data near the current time is set to be higher, so that the historical load index can reflect the current use state of the elevator better.
S102: when a call request is received, a response score for each elevator is calculated from the historic load indicators, where the response score is negatively correlated to the historic load indicators.
Wherein, calculating the response score of each elevator according to the historical load index can be realized by setting a function of the response score and the historical load index, namely: response score = f (historical load indicator), whereas a response score that is negatively correlated to a historical load indicator may be determined by setting the function to a function that is negatively correlated, e.g., inversely proportional.
It should be understood that the response score of an elevator may be related to the historic load index only, i.e. only the historic load index is considered and no other factors are considered. Of course, if the response score of the elevator is set to be only related to the historical load index, the riding experience of the elevator may be greatly influenced, for example, if the user at floor 1 calls the elevator, theoretically, the elevator at floor 2 and the elevator at floor 10 can respond, if the response score of the elevator is only related to the historical load index, the elevator at floor 10 may respond, but the elevator at floor 2 does not respond, and thus the riding experience of the user on the elevator may be influenced.
In one specific example, calculating the response score for each elevator based on the historical load indicators may include: calculating a response score for each elevator based on the historical load indicators and the current status indicators, wherein the current status indicators include, but are not limited to, at least one of: current registered floor, current elevator position, current car call, and elevator travel direction. Accordingly, the response score may be implemented by the following function: when the response score = f (historical load index, current state index), in specific setting, corresponding negative correlation or positive correlation sub-functions may be set for the historical load index and each current state index, respectively. The response score of the elevator is set to be related to the historical load index, and meanwhile, the current state of the elevator is considered, so that the response score of the elevator can be calculated by comprehensively considering factors related to the running efficiency of the elevator besides the historical use condition of the elevator, and the service life of the elevator and the running efficiency of the elevator are considered simultaneously when the elevator is used.
S103: the call request is dispatched to the elevator with the highest response score to respond.
After the response score for each elevator in the elevator system is calculated, the call request can be dispatched to the elevator with the highest response score to respond. Alternatively, when there are two or more elevators with the highest response scores, the call request can be randomly dispatched to the elevator with the highest response score to respond. When the response scores take more factors into consideration and two or more elevators with the highest response scores exist, the call request can be dispatched to the elevator with the smallest historical load index for response.
Optionally, after S101, that is, after obtaining the historical load index of each elevator in the elevator system, the method further includes: and if the current running state of the elevator system is in an idle state, increasing the weight of the historical load index in the calculation of the response score. The idle state can mean that all elevators of the elevator system are in the idle state, and can also mean that most elevators of the elevator system are in the idle state; correspondingly, a busy state of the elevator system means that all elevators are in operation, but also that most elevators of the elevator system are in operation. When the weight of the historical load index in the response score calculation is increased, the weight of the historical load index in the response score calculation can be replaced by a preset higher weight (which can be the weight corresponding to an idle state), for example, if the weight of the historical load index in the initial response score calculation is 0.2, when the elevator system is in the idle state, the weight of the historical load index is replaced by 0.4. Optionally, when the weight of the historical load index in the calculation of the response score is increased, the weight of some other factor or factors of the response score may also be decreased, for example, the weight of the position where the elevator is located may be decreased, which may be specifically set according to actual needs, and is not specifically limited here. Because more elevators can respond to the call requests when the elevator system is in an idle state, the weight of the historical load indexes in response score calculation is increased, the call requests can be dispatched to the elevators with the smaller historical load indexes in a more preferential manner to respond, and meanwhile, the riding experience of the elevators cannot be greatly influenced.
Optionally, after S101, that is, after obtaining the historical load index of each elevator in the elevator system, the method further includes: if the current operating state of the elevator system is in a busy state, the weight of the historical load index in the response score calculation is reduced. When the weight of the historical load index in the response score calculation is reduced, the weight of the historical load index in the response score calculation can be replaced by a lower weight (which can be the weight corresponding to the busy state), for example, if the weight of the historical load index in the initial response score calculation is 0.2, and when the elevator system is in the busy state, the weight of the historical load index is replaced by 0.1. Optionally, when the weight of the historical load index in the response score calculation is turned down, the weight of some other factor or factors in the response score calculation may be turned up, for example, the weight of the hall call registration of the elevator is turned up, which may be specifically set according to actual needs, and is not specifically limited here. When the elevator system is busy, if the weight of the historical load index in the response score calculation is higher, the situation that the elevator close to the call floor of the user does not respond can be caused, the riding experience of the elevator is influenced, and the weight of the historical load index in the response score calculation is reduced, so that the operation efficiency of the elevator system can be improved, and the influence on the riding experience of the elevator is avoided.
It will be understood that when the weighting of the historic load indicators in the response score calculation is adjusted down or up, it is necessary to first determine whether the current operating state of the elevator system is busy or idle. Optionally, when the current operation state of the elevator system is judged, the current operation state of the elevator system can be identified according to the current time and/or IO signal input data of the elevator system. For example, if the current time is in the time of the peak period of work attendance, the current running state of the elevator system can be identified as a busy state according to the current time, otherwise, the elevator system is in an idle state; or if the IO signal input of the elevator system exceeds a preset threshold value, identifying that the current running state of the elevator system is in a busy state, and otherwise, identifying that the elevator system is in an idle state.
In a specific example, if the historical load index cannot be obtained, and when a call request is received and the response scores of two or more elevators are the same, the call request is randomly dispatched to one of the elevators with the same response score. Because the response scores of two or more fixed elevators are the same when the response scores of the elevators are calculated, if the response scores of two or more elevators are the same, the call request is dispatched to a fixed elevator, the use loss of the elevator can be obviously increased, and the call request is randomly dispatched to one of the elevators with the same response score, so that the use loss of each elevator can be more balanced and close, and the service life of the elevator is prolonged. Optionally, if the historical load indexes of the elevators of the elevator system are difficult to count (for example, the weight of the elevator load cannot be counted because no weighing device exists), a small weight can be randomly assigned to the calculated response scores, so that the calculated response scores are different every time, a certain elevator or a plurality of elevators can be prevented from being frequently used, and the effect of balancing the use loss of each elevator is achieved.
Optionally, after S101, that is, after obtaining the historical load index of each elevator in the elevator system, the method further includes: the method comprises the steps of obtaining call frequencies of all floors in an elevator system, and dispatching idle elevators with historical load indexes lower than a first preset threshold value to floors with call frequencies higher than a second preset threshold value. The first preset threshold and the second preset threshold may be set according to the actual situation of the elevator system, and are not limited specifically here. When two or more floors with the call frequency higher than the second preset threshold exist, the idle elevator with the historical load index lower than the first preset threshold can be preferentially dispatched to the floor with the highest call frequency. Because the probability that the elevator is used by the floor with higher calling frequency is higher, the idle elevator with the historical load index lower than the first preset threshold value is dispatched to the floor with the calling frequency higher than the second preset threshold value, the response score of the elevator with the smaller historical load index is higher when other factors (such as the position of the elevator) are considered, so that the elevator is used preferentially, the used condition of the elevator with the larger historical load index is reduced, the use of each elevator in the elevator system is balanced, and the service life of the elevator and the use stability of the elevator system are improved.
According to the elevator dispatching method provided by the embodiment of the invention, the call request is dispatched to the elevator with the highest response score to respond by acquiring the historical load index of the elevator and calculating the response score of the elevator according to the historical load index of the elevator. Because the historical load index can reflect the loss condition of the elevator caused by the load, and the response score is negatively related to the historical load index, the call request is dispatched to the elevator with the highest response score to respond, and the elevator with less loss caused by the load can be preferentially used, so that the use of each elevator in the elevator system is balanced, and the service life of the elevator and the use stability of the elevator system are improved.
The steps of the above methods are divided for clarity of description, and may be combined into one step or split into multiple steps during implementation, and all steps are within the scope of the present patent as long as they contain the same logical relationship; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
