Fig. 1 is a schematic diagram of the elevator control system of embodiment 1.
Detailed Description
The invention will be described in further detail with reference to the drawings and the detailed description.
Example 1
The embodiment aims at the elevator waiting passengers at the main landing of the elevator, at the moment, the main landing of the elevator is 1 floor and the basement floor is not considered, namely, after all passengers leave the elevator car when the elevator arrives at the main landing from the lower floor, the elevator can only ascend at the main landing, so that the temperature requirement of the elevator waiting passengers at the landing in the elevator taking process is only considered.
The following describes the operation of the elevator control system of the present embodiment as follows:
Application scene: assume that the main landing of a building is floor 1 and floor 1 is the terminal floor, and that the building is provided with 4 elevators. In the early peak hours of the morning, there are 30 waiting passengers in the lobby of building 1, and it is now necessary to assign a response elevator to these 30 passengers, while controlling the set temperature of the air-conditioning in the response elevator such that the set temperature of the air-conditioning in the response elevator car coincides with the desired temperature of the passenger assigned to the response elevator.
As shown in fig. 1, the elevator control system of the present embodiment includes:
and a storage unit: for storing an influence element-desired temperature relationship reflecting a relationship between the influence element and the desired temperature that affects a desired temperature for the car when a passenger takes the elevator;
an acquisition unit: for obtaining a current value of the influencing element;
a receiving unit: the elevator system comprises a call signal and elevator operation information receiving module, a call signal receiving module and an elevator operation information receiving module, wherein the call signal receiving module is used for receiving call signals and elevator operation information of elevator waiting passengers;
a determination unit: determining the expected temperature of each waiting passenger according to the current value of the influence element and the relation between the influence element and the expected temperature;
grouping unit: dividing the waiting passengers into a plurality of groups according to the expected temperatures of the waiting passengers, wherein each group at least comprises one waiting passenger, and the expected temperatures of all the waiting passengers in the same group are the same, or the difference value between the highest expected temperature and the lowest expected temperature does not exceed a threshold value;
A blending unit: the elevator group allocation module is used for allocating response elevators to the call signals according to the elevator operation information and the group division result;
and a control unit: for maintaining the temperature in the responding elevator car in conformity with the desired temperature of the passengers in the group corresponding to the responding elevator by controlling the air-conditioning in the elevator car.
Before the elevator control system of this embodiment is applied to the above application scenario, it is necessary to first establish an influence element-expected temperature relationship by the storage unit, the storage unit first analyzes and determines the influence elements that can affect the expected temperature of the elevator car by the waiting passengers and that can be obtained, then determines possible values of the respective influence elements, then enumerates all combinations of possible values of the respective influence elements, and finally determines the expected temperature corresponding to each combination, thereby obtaining the influence element-expected temperature relationship.
The specific steps are exemplified as follows:
step 1, analyzing and determining influence elements which can influence the expected temperature of a waiting passenger on a car and can be acquired; the influencing elements here include one or more of the age, sex, dressing, current weather or air temperature, season, etc. of the passenger, only the age and dressing being considered here;
Step 2, determining possible values of all the influence elements; the age can be simply set to 4 possible values of children, young, middle-aged and elderly people, and the dressing can be simply set to cool dressing, spring and autumn dressing, thick and heavy warm suit and the like;
step 3, enumerating all possible combinations of values of each influence element; such as: combination 1: { young, cool dressing }, combination 2: { aged, spring and autumn }, combination 3{ middle-aged, spring and autumn }, etc.;
step 4, determining the expected temperature corresponding to each combination, for example: the desired temperature for combination 1 was 21 ℃, the desired temperature for combination 2 was 23 ℃, and the desired temperature for combination 3 was 22 ℃.
The influence factor-desired temperature relationship is thus obtained, and the elevator control system of the present embodiment can be applied to control the above-described scene.
The acquisition unit further includes:
and a determination module: for determining a source of the influencing element;
and a judging module: for whether there is currently a first influencing element for which a current value cannot be obtained from the source of the influencing element;
and an analysis module: when a first influence element exists, analyzing the relevance between the first influence element and a second influence element which can acquire the current value from the source of the influence element, and outputting an estimation method for estimating the current value of the first influence element by using the second influence element according to the relevance;
An estimation module: estimating and outputting the current value of the first influence element according to the estimation method and the current value of the second influence element which has relevance with the first influence element;
and an output module: when the first influence element does not exist, acquiring and outputting a current value of the influence element according to the source of the influence element; when the first influence element exists, a set of the estimated value of the first influence element and the current value of the second influence element is used as the current value of the influence element and output.
For the present application example, since the influence elements are only age and dressing, the determination module may determine that the sources thereof are both image processing apparatuses for performing image recognition on the waiting elevator passenger image captured by the landing camera; the judging module judges that the current values of all the influence elements can be obtained by the image processing device and are the second influence elements, and the output module outputs the image recognition result from the image processing device as the current value of the influence element. In this embodiment, the ages of the hall elevator passengers in building 1 acquired by the acquisition unit are young, middle-aged and elderly, the dressing is cool dressing and spring and autumn dressing respectively, and all fall into the foregoing 3 and combination, wherein 15 passengers in combination 1 are in line with 6 passengers in combination 2, and the rest 9 passengers are in line with combination 3; the specific implementation form of the acquisition unit for acquiring the influence elements is not limited, and the current value of the influence element may be obtained by detecting the identity information of the passenger and further according to the pre-registered information, or may be obtained by using a camera-image processing. In some application occasions, the influence elements may further include a season and a current air temperature, the season may be obtained by the date and time of the elevator system, but due to network abnormality and other reasons, the current air temperature may not be obtained directly from the original network path, then the judging module judges that the first influence element of the current air temperature exists, the analyzing module finds that the current air temperature may be obtained by analyzing the date and time information of the elevator system, or further combines with the dressing of the waiting passengers to obtain a rough estimation result, and at this time, the output module takes the combination of the actual values of the age, dressing and season and the estimation result of the current air temperature as the current of all influence elements and outputs the current result. By adopting this processing method, it is possible to avoid the occurrence of a phenomenon that the control system of the present embodiment cannot be used for control when the current value of the individual operation element cannot be directly obtained. Because of the influence element-desired temperature relationship, the corresponding desired temperature can be output only when the current values of all the operating elements are obtained.
The receiving unit is mainly used for receiving a calling signal (such as an uplink signal) and elevator running information (such as position information and running direction information of an elevator car and the like) from a 1-floor waiting passenger;
the determining unit determines the expected temperature of each waiting passenger according to the current value of the influence element and the relation between the influence element and the expected temperature; here, after the ages of the passengers are obtained as young, middle-aged, and elderly, respectively, the dressing is cool dressing and spring and autumn dressing, respectively, since they all fall into the above-described 3 combinations, the 3 different desired temperatures of 21 ℃, 22 ℃, and 23 ℃ for the 30 waiting ladders are determined according to the influence element-desired temperature relationship (i.e., the desired temperature to which the combination corresponds) that has been established in advance, while the determination unit also simultaneously determines the passengers corresponding to the respective desired temperatures.
Grouping unit: dividing the waiting passengers into a plurality of groups according to the expected temperatures of the waiting passengers, wherein each group at least comprises one waiting passenger, and the expected temperatures of all the waiting passengers in the same group are the same, or the difference value between the highest expected temperature and the lowest expected temperature does not exceed a threshold value; considering that in the present application scenario, the desired temperature has only 3 different values, so the waiting passengers are divided into A, B, C groups directly according to the desired temperature, corresponding to the 3 desired temperatures of 21 ℃, 22 ℃ and 23 ℃, respectively.
The allocation unit allocates the response elevators for each group according to the elevator operation information and the group division result, so as to provide transportation service for the elevator waiting passengers in the group, and the strong requirement is that the elevator allocation is to allocate the response elevators for the group instead of allocating the elevator for each call signal conventionally in response to the call signal, and for the scene of the main landing, the uplink call signal of the building 1 generally corresponds to a plurality of groups, so that one response elevator is allocated for each group, whereas in the conventional elevator allocation, only one elevator is allocated in response to the call signal (of course, part of the group management system may additionally add elevators in the case of identifying the peak period of time), but the scheme is obviously different from the scheme of allocating the response elevators for each group in the embodiment).
The allocating unit may adopt various allocating methods when allocating response elevators to each group, in this embodiment, allocating the response elevators to each group according to the response level of each group and the arrival sequence of each elevator, specifically: firstly, determining the response level of each group according to elevator call signals, then determining the first arriving elevator which arrives at the departure floor of the waiting passengers first according to elevator operation information, and finally distributing the intra-group call signal with the highest group response level to the first arriving elevator.
The groups are allocated to the responding elevators in this way in turn. The output result of the allocating unit comprises, in addition to the group and its corresponding elevator, the set temperature of the control and regulation device in the car of the responsive elevator (i.e. the desired temperature corresponding to the group).
The response level of the group is any of the following:
form 1, group waiting time, and the longer the waiting time of the group is, the higher the response level is;
form 2, highest priority of the group waiting passengers, and higher priority of the group waiting passengers has higher response level;
form 3, number of elevator passengers in group, and the response level of the group is higher the more elevator passengers in the group.
The waiting time of a group refers to the average waiting time, the sum of waiting times, the median of waiting times, or the longest waiting time of waiting passengers in the group.
After completion of the allocation of the response elevators to the respective groups, the allocation unit also needs to inform the waiting passengers of the allocation results in a suitable form so that the latter can be taken into the response elevator of the group to which it belongs, such as: the first arriving #a elevator car sets a temperature of 21 c, etc.
The control unit maintains the temperature in the responding elevator car in conformity with the desired temperature of the passengers in the group corresponding to the responding elevator by controlling the air conditioning in the elevator car.
In the above description, each group is allocated with a response elevator, and in fact, when the number of waiting passengers in the same group is excessive (such as exceeding the maximum passenger capacity of one elevator), a large group needs to be split into two groups, namely, when the number of waiting passengers in the group exceeds a threshold value, the waiting passengers in the group are split according to the principle of approaching the elements affecting the response level of the group in the group into the same group.
Preferably, the elements affecting the response level of the group (such as waiting time, priority, or when destination layer information is contained in the call signal) of the passengers in the group are separated into the same group as close as possible, and the destination layers contained in the group can be as few as possible or more concentrated as possible by grouping, so that the passenger conveying efficiency of the elevator is improved;
and when the number of passengers in one group is too small (e.g. far less than the maximum passenger capacity of one elevator), i.e. when the number of passengers in one group is less than the threshold value, if the difference between the response level of the group and the response level of the other group is less than the threshold value and the number of waiting passengers in both groups does not exceed the number of passengers that can be carried by the elevator, the two groups are combined to be handled.
Example 2
The present embodiment is directed to a passenger waiting for an elevator at an intermediate floor, and at this time, the elevator may go up or down after the intermediate floor is restarted, and the passenger waiting for an elevator may go up or down, so that the running direction of the elevator and the traveling direction of the passenger need to be considered when the passenger waiting for an elevator is allocated to respond to the elevator. For convenience of the following description, it is assumed here that the direction in which the candidate elevator, which is the response elevator of the waiting elevator passenger, starts running again after reaching the passenger waiting floor coincides with the traveling direction of the passenger, and thus the direction is not emphasized in the following description. The biggest difference between the intermediate floor and the terminal floor in example 1 is that when the elevator car arrives at the departure floor of the waiting passenger, there may be an original passenger in the elevator car who is not getting off the departure floor of the waiting passenger, and thus the problem of handling when the expected temperature of the original passenger is different from the expected temperature of the waiting passenger needs to be considered when allocating a response elevator for the passenger.
In addition, it is assumed here that the desired temperatures of all the intermediate floor waiting passengers are the same, and for the case where the desired temperatures of the intermediate floor waiting passengers are different, it is only necessary to select a waiting passenger corresponding to a certain desired temperature each time and employ an elevator control method to be described below, and then repeat the process.
The elevator control method provided by the embodiment comprises the following steps:
step S1, monitoring newly added elevator waiting passengers in an elevator waiting hall;
s2, acquiring a current value of an influence element influencing the expected temperature of the newly added elevator passenger on the elevator car;
s3, determining the expected temperature of the newly-increased waiting ladder passenger according to the current value of the influence element and the pre-established relation between the influence element and the expected temperature;
step S4, acquiring running information of each elevator and setting temperature of an air conditioner in a car of each elevator;
step S5, determining a to-be-selected elevator of the newly added elevator passenger according to the expected temperature of the newly added elevator passenger and the set temperature of the air conditioner;
step S6, selecting one elevator from the elevators to be selected as a response elevator for newly-increased elevator passengers according to the operation information of the elevators to be selected;
step S7, setting the set temperature of the air conditioner responding to the elevator as the expected temperature of the newly added elevator passengers.
In the above step S1, assuming that the expected temperatures of the newly added waiting passengers are the same each time, for the case where the expected temperatures of the waiting passengers are different, it is only necessary to select the waiting passenger corresponding to a certain expected temperature each time and adopt an elevator control method to be described below, and then repeat the process.
How to analyze the influence element that affects the passenger' S desired temperature for the car while riding the elevator, how to pre-establish the influence element-desired temperature relationship, how to obtain the current value of the influence element, and determine the desired temperature of the newly added elevator passenger according to the current value of the influence element and the influence element-desired temperature relationship in steps S2 and S3 are the same as those of embodiment 1, and are not described here.
In step S5, the method for determining the elevator to be selected for the newly added elevator passenger is as follows:
step S51, dividing the running elevators with the set temperature being the same as the expected temperature of the newly added elevator passengers or with the difference value between the set temperature and the expected temperature not exceeding a threshold value into a first elevator group, and giving a first priority; the running elevator is an elevator with the running direction being the same as the expected traveling direction of the newly added elevator passengers and the elevator car not passing through the departure floor of the newly added elevator passengers;
step S52, dividing each idle elevator into a second elevator group and giving a second priority to each idle elevator;
step S53, dividing the running elevators meeting the preset conditions and meeting the conditions that the set temperature is different from the expected temperature of the newly added elevator passengers or the difference value between the set temperature and the expected temperature exceeds a threshold value into a third elevator group, and giving a third priority; the preset conditions are as follows: the current farthest destination floor of the running elevator is positioned between the departure floor of the newly added elevator passengers and the current position of the elevator;
Step S54, dividing the running elevators which do not meet the preset conditions in the step S53 but meet the conditions that the set temperature is different from the expected temperature of the newly added elevator passengers or the difference between the set temperature and the expected temperature exceeds a threshold value into a fourth elevator group, and giving a fourth priority;
step S55, taking all elevators in the group which contains at least one elevator and has the highest priority as the candidate elevators, wherein the fourth elevator group is not included.
When there is only one elevator to be selected, step S6 takes the only one elevator to be selected as a response elevator for the newly added elevator passenger; when there are multiple elevators to be selected, in step S6, the method for selecting one of the elevators to be selected as the responding elevator of the newly added elevator passenger according to the operation information of the elevators to be selected is as follows:
if the elevator to be selected is from the first elevator group or the second elevator group, taking the call signal corresponding to the newly added elevator passenger as a newly added call signal, taking the elevator to be selected as a selection range, and adopting a group management algorithm to select;
if the elevator to be selected is from the third elevator group, the elevator with the smallest difference between the current temperature of the elevator car and the expected temperature of the newly added elevator passengers is taken as the response elevator.
After the original free elevator in the second group is selected as the response elevator of the newly added elevator passenger, the elevator needs to be updated to the expected stability of the newly added elevator passenger after the set temperature of the elevator is updated to the running elevator after the newly added elevator passenger is newly added later.
When the current temperature in the elevator car is different from the expected temperature of the newly added elevator passengers, the step S7 determines the starting time of temperature adjustment according to the difference between the current temperature and the expected temperature and the temperature adjustment speed of the air conditioner.
When the response elevator comes from the third elevator group, if the movement time of the response elevator to the departure floor of the newly added elevator passenger is less than the time required by the air conditioning device of the response elevator to adjust the current temperature to the expected temperature of the newly added elevator passenger, the existing passengers and the newly added elevator passengers in the elevator car need to be considered, such as: the temperature adjustment start time is determined in response to the number of existing passengers and newly added passengers in the elevator car. When the former is larger than the latter, the adjustment is started after the existing passenger gets off the elevator, otherwise, the temperature adjustment starting time is the time when the temperature adjustment is completed when the elevator car reaches the departure floor.
Preferably, the elevator control method further comprises: step S8, informing the allocation result of the response elevator;
when the call signal of the newly added waiting passengers comprises a destination floor, the call signal is informed in a corresponding relation mode between the destination floor and the elevator ID, otherwise, the call signal is informed in a corresponding relation mode between the set temperature and the elevator ID.
And when the elevator to be selected cannot be selected in the step S5, waiting to monitor that the elevator operation information changes, and returning to the step S1.
Example 3
The present embodiment is based on embodiment 2, with the following steps added between step S1 and step S2:
step A1, judging whether a plurality of newly-increased waiting ladder passengers are monitored and the maximum distance between the newly-increased waiting ladder passengers exceeds a threshold value, if so, entering the next step, otherwise, entering the step S2;
step A2, grouping the newly-increased waiting elevator passengers by adopting a clustering method based on the position information of the newly-increased waiting elevator passengers or the distance information between the newly-increased waiting elevator passengers;
step A3, selecting one of all unselected groups as a selected group, and taking the newly-increased waiting ladder in the selected group as a newly-increased waiting ladder passenger;
and, after step S7, the steps of:
and B1, judging whether an unselected group still exists, if so, updating elevator operation information and returning to the step A3, otherwise, ending.
The step A3 selects the selected group according to an optimal principle, wherein the optimal principle is as follows:
firstly, according to a pre-established evaluation index and an evaluation method, for each possible selection order formed by different arrangement orders of each group, the control performance (such as elevator energy consumption, passenger waiting time and the like) of the response elevator of each selected group is evaluated by using the evaluation index and the evaluation method corresponding to each possible selection order, so as to obtain an evaluation result of a single group, further obtain a total evaluation result of all selected groups, further obtain a total evaluation result corresponding to each selection order, and finally select the selection order corresponding to the optimal total evaluation result as a final selection order.
Said step S6 is aimed at making full use of the resources currently available in the elevator car for transporting passengers or at the most for selecting a responding elevator for a newly added waiting passenger with the same destination floor of the passengers in the elevator current car as the destination floors of the waiting passengers in the selected group. The resources for transporting passengers, such as car congestion, floor occupation, residual load capacity, the difference between the nominal load capacity and the current weighing result of the weighing device, etc.
The step S6 is implemented by selecting as the responding elevator one of the elevators to be selected that can provide resources close to but not less than those required by the waiting passengers in the selected group, in order to make full use of the resources currently available to the elevator car for transporting the passengers.
Of course, when it is possible to determine the destination floor information of the waiting passengers in the respective groups (e.g. call signals registered with a mobile terminal or destination floor registration device), it is also possible to take as the responding elevator the elevator with the most identical destination floor of the passengers in the current car of the elevator as the destination floor of the waiting passengers in the selected group.
The present invention has been described in detail by way of specific embodiments and examples, but these should not be construed as limiting the invention. Many variations and modifications may be made by one skilled in the art without departing from the principles of the invention, which is also considered to be within the scope of the invention.
