Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
The embodiment of the invention discloses an elevator control method based on energy consumption priority, which is implemented by a main execution body called an elevator control system and is constructed by software and hardware, wherein the hardware part is used for receiving the actual number of people in an elevator when a target is called out, the called out situation and the called in situation when the target is called out and directly or indirectly sending control signals of corresponding target called out requests to the target elevator, and the software part is mainly used for calculating the predicted load of each elevator according to the actual number of people in the elevator when the target is called out, the called out situation and the called in situation when the target is called out, so as to calculate the relative energy consumption value of each elevator and determine the target elevator (target first elevator or target second elevator) responding to the target called out request.
The embodiment of the invention is suitable for various types or types of elevator control modes with preferential energy consumption, whether each elevator has an unfinished call request or not, can be realized by the method of the embodiment of the invention, and in the preferred embodiment of the invention, the actual energy consumption value of the elevator is not involved, and the relative energy consumption value is only determined according to the relation between the predicted load and the rated load, thereby having wider application range.
It will be appreciated that although the embodiments of the present invention relate to an elevator control scheme with energy-consumption prioritization, in some scenarios, the energy-consumption prioritization and the time prioritization can be switched between each other, where the time prioritization can be implemented in a conventional manner, such as by hardware, e.g. by control buttons, or by software, e.g. by operating with a corresponding APP or applet.
The embodiment of the invention predicts the number of people corresponding to the allocated recall condition and the recall condition when the target recall request is carried out in a deep learning mode, wherein the number of people predicted by the allocated recall condition is recorded as the number of people entering a elevator, and the recall condition is the number of people predicted by the recall when the current floor (the floor where the elevator is located when the target recall request is carried out) reaches the floor where the target recall request is located, and is recorded as the number of people exiting the elevator.
For example, referring to fig. 1, assume that the floor corresponding to the target call request is at floor 11, the call request is up, a certain elevator a is at floor 2, and 3 persons are in the car; the registered call is 7 floors, and the number of the elevator is predicted to be 1 person; the number of the elevator entering people is predicted to be 2, the predicted destination floors of the elevator entering are 9 floors and 13 floors, and the number of the elevator exiting people is predicted to be 1. So, assuming that the elevator responds to the target call request, the predicted number of passengers in the elevator before the elevator responds is 3 (actual number of passengers in the elevator) +2 (predicted number of passengers entering the elevator) -1 (predicted number of passengers exiting the elevator after the elevator is allocated) =3. The predicted load can be determined by the relationship between the predicted number of persons and the rated number of persons, and the predicted load is 3/10=30% assuming that the rated number of persons is 10 persons.
The embodiment of the invention judges the energy consumption value of each elevator by predicting the load, when one or more calls are allocated, the target elevator responding to the new call can be determined according to the calculated energy consumption value, the application scene of the energy consumption priority allocation mechanism is increased, and the embodiment of the invention judges the specific target elevator by adopting the relative energy consumption without calculating the absolute energy consumption value of the elevator, thereby improving the application range of the energy consumption priority allocation mechanism.
Example 1
Referring to fig. 2, fig. 2 is a schematic flow chart of an elevator control method based on energy consumption priority according to an embodiment of the present invention. As shown in fig. 2, the energy consumption priority-based elevator control method may include:
s110, receiving a target call request, and determining the predicted load of the first elevator cluster according to the target call request.
The first elevator group here refers to the set of all elevators traveling in the same direction as the target call request and to the floor where the target call is located. Illustratively, assuming that an elevator is at floor 15 and descending, and the target call request is a 16-floor descending, the elevator is not part of the first elevator cluster.
When the elevators of the first elevator cluster respond to the target call request, the actual number of the elevators needs to be determined firstly, namely, the actual number of the elevators when the target call request occurs, the actual number of the elevators can be obtained in various modes, and the image acquisition device such as a camera and the like can be used for acquiring images, and then the actual number of the elevators can be determined based on image recognition technologies such as a feature recognition method, a shape recognition method, a model learning method, a crowd density recognition method and the like, and of course, the actual number of the elevators can also be determined by adopting the ratio of the actual load to the average load, and can also be determined by sensing signals such as an optical curtain sensor, an infrared sensor, a thermal imaging sensor and the like.
Secondly, the number of people who enter the elevator corresponding to the allocated call is determined. In a preferred embodiment of the invention, since the elevator may have been allocated one or more other calls when responding to the destination call request, these allocated calls also need to be counted when the elevator arrives or does not arrive at the floor on which the destination call request is located (denoted as destination floor).
Taking elevator a as an example, because floor 5 has an assigned call, the number of calls to floor 5 needs to be counted, and in other embodiments, floor 12 is assumed to be assigned a call even though the call was made after the target call request, but is counted.
The floor between the current floor of elevator a and the destination call request (including the current floor and the destination floor) is designated as the first floor, the floor outside the first floor is designated as the second floor, and in some other embodiments, only the number of people called outside and inside the first floor may be counted, and the called outside of the second floor may be reassigned.
The number of people who enter the elevator corresponding to the allocated call can be realized in a predictive mode. For example, the time (time of year, month, day, minute, second), departure floor, destination floor may be used as a tag, the historical data may be trained, and the obtained model may be used to predict the number of people currently called to a floor.
The model can be realized in various ways, and can be realized by adopting a deep learning network, for example, the number of passengers entering a elevator and the number of passengers exiting the elevator can be predicted by using an LSTM long-term memory network model, and of course, the number of passengers entering the elevator can be predicted by using the method, for example, an elevator traffic demand predictor disclosed in the publication No. JP 2005335893A.
And thirdly, predicting the number of the people going out of the call-in situation, and recording the predicted number as the first number of people going out of the elevator, wherein the first number of people going out of the elevator is the predicted number of people going out of the floor which has triggered the call-in operation, and the first number of people going out of the elevator does not contain the number of people going out of the elevator after the elevator reaches the target floor.
Assuming that the elevator runs in floor 2 and the target call request occurs at floor 10, there are 6 floors and 15 floors of calls, only the number of passengers leaving floor 6 is predicted, but not the number of passengers leaving floor 15 is predicted when the target call request is responded.
The first number of passengers leaving the elevator predicted by the call can also be realized in a similar manner, namely, the first number of passengers leaving the elevator is determined by training a determined prediction model through historical data.
Finally, the number of outgoing calls before the destination floor, which may occur in the allocated outgoing calls, is also predicted, and is recorded as the second number of outgoing calls (i.e., the predicted number of incoming calls), for example, the elevator runs on floor 2, the target outgoing call request occurs on floor 10, the floor on which the allocated outgoing calls are located is floor 6, the number of incoming calls corresponding to the outgoing calls is predicted to be 3, the outgoing floor and the number of outgoing calls also need to be predicted, and the second number of outgoing calls is 2 (i.e., the number of outgoing calls from floor 9 and floor 10) provided that the 3 persons are predicted to be outgoing calls from floor 9, floor 10 and floor 15, respectively. The prediction of the number of second passengers going out of the elevator can be realized by adopting a similar method.
Based on the four possible situations, the predicted number of people, i.e. P, of each elevator in the first elevator group is determined i ＝P i1 +P i2 -P i3 -P i4 ，P i For the predicted number of people, P, of the ith first elevator i1 For the current number of people, P, of the first elevator at the i-th part i2 For predicting the number of people entering the elevator for which the first elevator at the i-th part is allocated i3 For the first number of passengers leaving the first elevator at the i-th part, P i4 The number of second passengers who are predicted for the first elevator at the i-th section.
It can be understood that the elevators in the first elevator cluster may also be subjected to preliminary screening, where the preliminary screening is to sum the predicted number of people and the predicted number of people requested by the target call, and if the predicted number of people is greater than the rated number of people, the corresponding elevator is not used as a part of the first elevator cluster, and the predicted number of people requested by the target call is similar to the above prediction method.
In the preferred embodiment of the invention, the predicted load is the ratio of the predicted number of people to the rated number of people, also called relative load, so that the calculated energy consumption value is the relative energy consumption value, and in the process, the running condition of the elevator is not considered, for example, the data such as the current, the voltage and the like of the elevator are not acquired and calculated, thereby improving the application range.
The calculation formula of the predicted load is:
wherein X is i The predicted load of the first elevator at the i-th section.
And S120, determining the energy consumption value of each first elevator in the first cluster according to the predicted load of the first elevator cluster and the running direction of the first elevator cluster.
In the embodiment of the invention, the energy consumption value of the elevator is related to the running direction of the elevator, the energy-saving running state of the elevator is light-load ascending and heavy-load descending, the energy-saving running state of the elevator is light-load descending and heavy-load ascending, the running state of the elevator can be represented by the balance coefficient, the balance coefficient can be regarded as a middle point between the energy-saving running and the energy-saving running of the elevator, for ascending, the elevator is heavy-load ascending, namely, the energy-saving running state is more far from the balance coefficient, the energy is more consumed, otherwise, the elevator is light-load ascending, the elevator is in the energy-saving running state is more energy-saving, and the elevator is more energy-saving when the balance coefficient is more far from the balance coefficient. By way of example, assuming a balance factor of 45%, the closer the load of the elevator is to 0%, the more energy is saved, and the closer to 100%, the more energy is consumed.
For descending, if the balance coefficient is exceeded, the elevator is in heavy-load descending, at the moment, the elevator is in an energy-saving running state, and is far away from the balance coefficient, the more energy is saved, otherwise, if the balance coefficient is not exceeded, the elevator is in light-load descending, the elevator is in an energy-consuming running state, and the more far away from the balance coefficient, the more energy is consumed. By way of example, assuming a balance factor of 45%, the closer the load of the elevator is to 100%, the more energy is saved, while the closer to 0% the more energy is consumed.
The balance coefficients of the uplink and the downlink can be the same or different, and can be set according to specific situations.
Based on the relation between the balance coefficient and the predicted load, the running states of the elevators are overlapped, and the energy consumption value of each first elevator is determined.
Specifically, when the first elevator traveling direction is upward, the energy consumption value thereof can be written as:
wherein Y is a balance coefficient, E i The energy consumption value of the first elevator at the i-th part is K, and K is a constant. For example, the balance coefficient of the uplink may be 45%, and K may be 110%, which may be arbitrarily set.
For uplink, when X i Less than or equal to the preset balance coefficient, the elevator is operated in an energy-saving state, and X i The smaller the corresponding E i The smaller, when X i If the balance coefficient is larger than the preset balance coefficient, the elevator is operated in the energy consumption state, and X i The larger the corresponding E i The larger, therefore, it is known from the above relationship between uplink load and energy consumption that when the target recall request is uplink, E is selected i The smallest first elevator responds to the target call request for the most energy saving.
When the running direction of the first elevator is downward running, the energy consumption value E is:
the balance coefficient for the downstream may be set to 45% or other values as needed.
For downlink, when X i Greater than or equal to the preset balance coefficient, the elevator is operated in an energy-saving state, and X i The larger the corresponding E i Smaller (E) i Possibly negative), when X i If the balance coefficient is smaller than the preset balance coefficient, the elevator is operated in the energy consumption state, and X i The smaller the corresponding E i The larger, therefore, in combination with the above relationship between the downlink load and the energy consumption, it is known that when the target recall request is downlink, E is also selected i The smallest first elevator responds to the target call request for the most energy saving.
And S130, determining a target first elevator according to the energy consumption value, and responding to the target call request.
From the above, whether ascending or descending, when the elevator is in the energy-saving running state and the predicted load is farther from the balance coefficient, the elevator can be selected as the target first elevator to respond to the target call request.
As can be seen from the calculation in step S120 described above: the smaller the energy consumption value is, the more energy-saving the corresponding first elevator is compared with other first elevators in the first elevator cluster, so that the target first elevator can be determined according to the energy consumption value, namely, the first elevator with the smallest energy consumption value is selected as the target first elevator to respond to the target recall request.
Example two
Referring to fig. 3, fig. 3 is a flow chart illustrating another elevator control method based on energy consumption priority according to an embodiment of the present invention. As shown in fig. 3, the energy consumption priority-based elevator control method may include:
s210, receiving a target call request, and judging whether a first elevator cluster exists.
If there is a first elevator cluster that is consistent with the direction of the target call request and that is routed to the floor where the target call is located, then operation is performed in the manner of embodiment one described above.
If there is no first elevator cluster consistent with the direction of the target call request and passing through the floor where the target call is located, for example, if a certain call request corresponds to downlink and all elevators are in an uplink state, then there is no first elevator at this time, for example, if a target floor corresponding to a certain call is 15 floors and is downlink, when all elevators are in an uplink state or/and a downlink state below 15 floors, there is no first elevator at this time.
For the absence of the first elevator group, then the response to the target recall request may be suspended until the first elevator appears, or a predicted load of the second elevator group is determined, and the target recall request is responded to based on the predicted load of the second elevator group. The second elevator cluster refers to a set of second elevators that are not consistent with the direction of the target call request or that are consistent in direction but do not pass through the floor on which the target call is located.
S220, determining the energy consumption value of each second elevator in the second cluster according to the predicted load of the second elevator cluster and the running direction of the second elevator cluster.
Since the second elevator in the second elevator cluster is either inconsistent with the running direction of the target call request or does not pass through the floor where the target call request is located, the final energy consumption value can be determined by means of piecewise calculation for the energy consumption value of the second elevator.
For example, assuming that the direction of the target call request is downlink and the running direction of the second elevator is uplink, the energy consumption value when the second elevator ascends to the highest floor is calculated first, and is recorded as a first energy consumption value, and the calculation method of the first energy consumption value is similar to the uplink calculation method of the first elevator in the first embodiment, and the highest floor is the highest floor allocated with the call, the highest floor predicted by the call, and the maximum value of the highest floors predicted by the call allocated with the call. And then calculating the energy consumption value of the descending of the highest floor, recording the energy consumption value as a second energy consumption value, wherein the calculation method of the second energy consumption value is similar to the descending calculation mode of the first elevator in the first embodiment, and finally accumulating the first energy consumption value and the second energy consumption value to determine the total energy consumption value of the second elevator.
Similarly, when the direction of the target call request is upward and the running direction of the second elevator is downward, the first energy consumption value of the second elevator running downward and the second energy consumption value of the upward are respectively calculated by taking the lowest floor reached by the second elevator as the middle point, and the total energy consumption value of the second elevator is determined.
Of course, the running directions are consistent, but the energy consumption value of the second elevator can be divided into three sections without passing through the floors of the target call request, the energy consumption values of the three sections are calculated respectively, and then accumulation is carried out, for example, when the floor where the target call request is located is 15 floors and descends, the second elevator is also descending, and when the second elevator is located at 10 floors when the target call request occurs, the energy consumption value of the second elevator is divided into three sections, the first section is that the second elevator runs downwards to the lowest floor, the first energy consumption value is determined, the second section is that the second elevator runs upwards to the highest floor, the second energy consumption value is determined, the third section is that the second elevator runs downwards to the highest floor, the third energy consumption value is determined, and the three energy consumption values are accumulated, so that the total energy consumption value of the second elevator is obtained.
And S230, determining a target second elevator according to the total energy consumption value of the second elevator, and responding to the target call request.
Similar to the embodiment, the smaller the total energy consumption value of the second elevator, the more energy-saving is illustrated, and therefore, the second elevator with the smallest total energy consumption value can be targeted to the second elevator to respond to the targeted call request.
In some other embodiments, the first elevator cluster and the second elevator cluster may be combined, that is, the predicted load of the first elevator cluster and the predicted load of the second elevator cluster are determined, then the energy consumption value of each first elevator of the first elevator cluster and the total energy consumption value of each second elevator of the second elevator cluster are determined according to the request direction of the target call request, and then the smallest energy consumption value or the total energy consumption value is selected as the target elevator to respond to the target call request.
In some other embodiments, it may also relate to a stopped elevator, and for calculating the energy consumption value of the stopped elevator (denoted as a fourth elevator), the direction of the fourth elevator is set according to the floor where the fourth elevator is located and the destination call location, for example, the fourth elevator is stopped at floor 3, the destination call request is that the fourth elevator goes up floor 2, and then the direction of the fourth elevator may be that the fourth elevator goes down floor 2 and goes up floor 2.
In some other embodiments, when the directions of the elevators are changed, new energy consumption values corresponding to the elevators with the changed directions can be recalculated, then the target first elevator or the second elevator is given to the target call request according to the recalculated energy consumption values of the elevators to update, and the change of the directions of the elevators can be any of the change of the directions of the elevators from ascending to descending, the change of the directions of the elevators from descending to ascending, the change of the directions of the elevators from ascending or descending to stopping, and the change of the directions of the elevators from ascending or descending to descending. Of course, in order to avoid frequently updating the response elevator corresponding to the target recall request, the user experience is too affected, and the update frequency and the update times may also be set, for example, the update frequency of the target recall request is 30 s/time, the update times cannot exceed 3 times, and the like.
In other embodiments, the energy consumption priority and the user experience priority may also be combined, and the first elevator or the second elevator may be ranked from small to large according to the energy consumption value, and then the one with the shortest arrival time at the target floor is selected as the final responding elevator in the front part (for example, the first 3 or the first 5, etc.) of the ranking.
Example III
The third embodiment is an improvement of the first or second embodiment, in which when the related operation is performed in the case where the energy consumption values are equal, when there is a first elevator or a second elevator with the smallest energy consumption value, the first elevator or the second elevator with the smallest energy consumption value is used as the target elevator to respond to the target call request, and if a plurality of energy consumption values are equal and are all the smallest, the operation is performed in the manner of the third embodiment.
When there are a plurality of minimum values with equal energy consumption values, the elevators with equal energy consumption values and minimum values are marked as a third elevator cluster, and referring to fig. 4, the method specifically includes the following steps:
s310, judging whether the operation state of the third elevator cluster is an energy-saving operation state or an energy-consuming operation state.
Because the energy consumption value is calculated, the energy-saving running state and the energy consumption running state are obviously distinguished, and therefore, the running states of the elevators of the third elevator cluster are both in the energy-saving running state or the energy consumption running state.
The operation of step S320 is performed when the elevators of the third elevator group are in the energy-saving operation state, and the operation of step S350 is performed when the elevators of the third elevator group are in the energy-consuming operation state.
S320, judging the distance between each elevator of the third elevator cluster and the floor where the target call request is located.
The elevator in the energy-saving running state has more energy storage as the distance from the floor where the target call request is located is longer, so that the energy is saved more.
Thus, if there is a maximum floor spacing of one elevator from the floor on which the target call request is located in the third elevator cluster:
s330, selecting an elevator with the largest floor spacing from the floor where the target call request is located to respond to the target call request; otherwise, if there are a plurality of floors with equal floor spacing from the floor where the target call request is located and the floor spacing is the maximum value, then:
s340, selecting any one of the elevators with equal floor spacing and maximum value from the floors where the target call requests are located to respond to the target call requests, or selecting one of the elevators with the smallest or largest elevator number from the elevators with equal floor spacing and maximum value from the floors where the target call requests are located to respond to the target call requests.
S350, judging the distance between each elevator of the third elevator cluster and the floor where the target call request is located.
The closer the elevator in the energy-consuming running state is to the floor where the target call request is located, the smaller the power consumption is relatively.
Thus, if there is a minimum floor spacing of one elevator in the third elevator cluster from the floor on which the target call request is located, then:
s360, selecting an elevator with the smallest floor spacing from the floor where the target call request is located to respond to the target call request; otherwise, if there are a plurality of floors with equal floor spacing from the floor where the target call request is located and the floor spacing is the minimum, then:
and S370, selecting any one of the elevators with equal floor spacing and minimum value from the floor where the target call request is located to respond to the target call request, or selecting one of the elevators with equal floor spacing and minimum value from the floor where the target call request is located to respond to the target call request, wherein the elevator number is the smallest or the largest.
In some other embodiments, if the total energy consumption value of the second elevator corresponds to the second embodiment, it is also possible that the total energy consumption value is equal and is the smallest, but the partial sectional operation state of the second elevator is the energy-consuming operation state and the partial sectional operation state is the energy-saving operation state, in which case the target second elevator responding to the target recall request may be selected by setting weights.
Illustratively, the distance between the second elevator and the floor where the target call request is located is calculated in a segmented manner, and each segment is in an energy-saving running state or an energy-consuming running state, and then:
l=αl1+βl2, where α+β=1, L1 is the cumulative distance (cumulative floor number) of one or more energy-saving operation segments, L2 is the cumulative distance of one or more energy-consuming operation segments, α and β are weights corresponding to L1 and L2, respectively, and are set as needed, for example, if energy storage is emphasized more, α can be set to be close to 1, a second elevator with the largest L value is selected as a target elevator, if energy consumption in the energy-consuming operation state is emphasized more, β can be set to be close to 1, and a second elevator with the smallest L value is selected as a target elevator.
