Description
Technical Field
The invention relates to the field of elevators, in particular to an elevator control method and an elevator control system.
Background
At present, an elevator can wait for a contracted departure floor before a designated time according to the preset contract of a passenger, and after the passenger reaches the departure floor at the contracted time, the passenger can enter an elevator car without waiting so as to start the elevator taking process. However, in practical application, the actual arrival time of the passengers who reserve to get up to the reserved departure floor may be slightly earlier than the reserved getting up time, or may be later than the reserved getting up time. When a reservation boarding passenger gets to the boarding delay, an elevator for responding to the reservation of the boarding usually waits for a period of time at the departure floor, and when the reservation passenger does not reach the contracted departure floor within the specified waiting time, the elevator leaves the contracted departure floor to respond to other boarding call signals. Obviously, waiting for an elevator due to the late arrival of a scheduled boarding passenger can adversely affect the operating efficiency of the elevator and can create additional power consumption, particularly when the scheduled boarding moments are relatively concentrated and the number of boarding reservations exceeds the number of elevators.
In this way, it is a technical problem to be solved how to reduce or even eliminate the decrease in elevator operation efficiency and the increase in energy consumption caused by the delay of the passengers waiting for the elevator.

Detailed Description
Other advantages and effects of the present invention will become readily apparent to those skilled in the art from the following disclosure, when considered in light of the accompanying drawings, illustrating embodiments of the present invention by way of specific embodiments. In the following description, specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced or carried out in other, different embodiments, and details of the present description may be set forth in various different manners and applications, as those skilled in the art may readily devise various arrangements and substitutions without departing from the spirit of the present invention.
Example 1
In this embodiment, the elevator control method includes:
step A1, determining landing delay information when a passenger fails to arrive at a landing floor of a reserved landing in time when the reserved landing is fulfilled;
the passengers are reservation boarding passengers, the failure to arrive at the reservation boarding departure floor in time means that the difference obtained by subtracting the reservation boarding moment from the actual arrival moment of the passengers when fulfilling the reservation boarding is larger than a time threshold gamma, wherein gamma is a non-negative real number;
a2, determining the priority of the passenger according to the boarding delay information;
and step A3, controlling an elevator to provide transportation service for the passengers according to the priority.
In step A1, the boarding delay information includes information about a passenger in a reservation boarding, such as: one or more of passengers, scheduled boarding moments, scheduled boarding departure floors, or may also include scheduled boarding destination floors, etc.
In step A2, a reservation arrival indicator capable of representing the arrival condition of the passenger's arrival is first constructed based on the information of the passenger's arrival, then the reservation arrival indicator of the passenger (or further defined within a specified period) is calculated using the arrival information, and finally the arrival priority of the passenger (within the specified period) is determined based on the reservation arrival indicator.
The reservation arrival index may be an arrival time index within a given range, an index based on arrival time within a given range (hereinafter referred to as an arrival time index), or a combination of the arrival time index within a given range and the arrival time index within a given range (hereinafter referred to as an arrival time index). The boarding delay times comprise absolute delay times and relative delay times, the absolute delay times are times that the passengers in a given range cannot arrive at the reservation boarding departure floor in time when the reservation boarding is fulfilled, and the relative delay times are quotient of the absolute delay times in the given range and the total times that the passengers in the given range fulfill the reservation boarding. The range here is one of the following cases:
case 1, historical boarding data of all passengers;
2, taking the historical elevator taking data in a time window with the current moment as the terminal point;
case 3, last n times historical boarding data of the passenger, wherein n is a positive natural number.
In the statistics of the times, the ranges may be further refined, for example: one or more of reserving passengers, reserving a time period when taking a ladder, reserving a departure floor when taking the ladder, and the like. For example, for the range 1, after three limiting conditions of the reserved passengers, the time period of the reserved boarding time and the reserved boarding departure floor are added at the same time, the number of all boarding reservations of the specific reserved passengers taking the 10 th floor as the departure floor in the specific time period (such as 9:00-9:30 am) is counted, and the absolute late arrival times are obtained. The reference to the absolute late times can be readily obtained to the relative late times, and is not repeated here.
For the delay time index, firstly, calculating the actual delay time of each elevator taking reservation according to the elevator taking delay information (mainly by subtracting the reserved elevator taking time from the actual elevator taking time), thereby obtaining the elevator taking delay time information required by calculating the delay time index; then determining a range by referring to the delay time index to obtain elevator taking delay time information in the range; and finally calculating the delay time index by utilizing the delay time information of the elevator in the range. It is emphasized that the calculation of the late time index here is relatively complex compared to the statistics in the late time index. The specific construction of the late time index may take many forms, such as: the delay time index is the sum of the boarding delay time information in the range, the delay time index is the weighted sum of the boarding delay time information in the range (the larger the single delay time is, the larger the weight coefficient is), and the delay time index is the maximum value, the average value or the median of the boarding delay time information in the range. In general, the late time index should satisfy: the larger the boarding delay time information in the range is, the larger the value of the boarding delay index is.
For the delay time index and the delay time index, the delay time index and the delay time index can be obtained by calculation respectively, and then the delay time index and the delay time index are obtained by calculation by using the delay time index and the delay time index, for example, the delay time index and the delay time index are obtained by calculating the weighted sum of the delay time index and the delay time index.
After the reservation boarding delay index is obtained by the above-described method, a description is given next of how to prioritize the passenger or boarding reservation by the reservation boarding delay index. Note that the priority here may be for the passenger, may be for a period in which the scheduled boarding time is located, may be for the scheduled boarding departure floor, or may be a combination of a plurality of the foregoing, depending on the range of boarding delay times and/or boarding delay time information when calculating the scheduled boarding delay index. For prioritization of priorities for objects, any of the following approaches may be employed:
in the mode 1, the possible value range of the reservation riding index is divided into a plurality of sections in advance, each section corresponds to one priority, and the smaller the index value is, the lower the corresponding priority is. Thus, after the specific numerical value of the reserved elevator taking delay index is obtained, the corresponding priority is found out only according to the interval at the reserved elevator taking delay index;
mode 2, the reservation arrival indexes corresponding to the priority-oriented objects are sorted from small to large, and the higher the priority is, for example: the priority level of the first rank is highest, and the priority level of the last rank is lowest.
In the foregoing description, the boarding delay information is boarding information that a passenger fails to arrive at the reservation boarding departure floor in time when the passenger fulfills the reservation boarding, and the basis for judging that the passenger fails to arrive at the reservation boarding departure floor in time is that a difference obtained by subtracting the reservation boarding time from the actual arrival time of the passenger when the passenger fulfills the reservation boarding is greater than a time threshold value γ, wherein γ is a non-negative real number. Strictly speaking, the arrival at the departure floor of the reservation ramp is delayed as soon as the passenger arrives later than the time of the reservation ramp, and the time threshold value gamma=0 at this time is a very severe condition. In fact, when the difference obtained by subtracting the scheduled boarding time from the actual arrival time is a very small positive number, even if waiting for the scheduled passenger is still required, the influence on the running efficiency of the elevator is very limited and the passenger experience of the passenger is facilitated to be improved, so that the passenger with very small arrival time does not need to be reminded, so that when the passenger with very small arrival time is subjected to priority service and is reminded, on the basis of the definition of the scheduled boarding delay (namely, the difference is larger than the time threshold gamma), the condition can be properly relaxed when the boarding delay information to be adopted is determined, and the delay information at this time corresponds to the case that the difference obtained by subtracting the scheduled boarding time from the actual arrival time when the passenger fulfills the scheduled boarding is larger than the time threshold beta, wherein beta > gamma. For example, originally γ=0, and β=5 seconds.
When the number n of the specific elevator taking reservations (n is a positive natural number) is larger than the number m of the response elevators (m is a positive natural number) which can be used for responding to the elevator taking reservations, the step A3 controls the response elevators which can be used for responding to the elevator taking reservations according to the priorities of the passengers corresponding to the specific elevator taking reservations, so that the specific elevator taking reservations of the passengers with high priority are preferentially responded, and the transport service is preferentially provided for the passengers with high priority.
The specific elevator taking reservation refers to a first reservation elevator taking which simultaneously meets the following conditions:
condition 1, at least one second reservation riding ladder exists;
the reservation elevator taking time of the first reservation elevator taking is earlier than the reservation elevator taking time of the second reservation elevator taking;
and 3, after the first reservation elevator taking service is completed, a certain elevator does not need to respond to the second reservation elevator taking service, so that if the first reservation elevator taking service and the second reservation elevator taking service are responded in time, only two elevators can be allocated to respond to the first reservation elevator taking service and the second reservation elevator taking service respectively.
The elevator control method estimates the moving time required by the elevator to move from the starting floor of the reservation elevator to the destination floor of the reservation elevator according to the reservation elevator taking time of the first reservation elevator taking, the reservation elevator taking departure floor of the reservation elevator taking and the reservation elevator taking time of the reservation elevator taking of the second reservation elevator taking, calculates the time interval between the reservation elevator taking time of the first reservation elevator taking and the reservation elevator taking time of the second reservation elevator taking, and judges that a certain elevator does not respond to the second reservation elevator taking after completing the service of the first reservation elevator taking according to the time interval and the moving time or according to the actual arrival time in the time interval, the moving time and the historical elevator taking data.
The elevator control method compares the movement time with a time interval minus a non-negative time margin deltat and determines that it is not time-consuming when the movement time is greater than the time interval.
The elevator control method subtracts the reserved boarding time from the actual arrival time in the historical boarding data of the passenger, takes the obtained difference as an arrival time deviation amount, and further determines the time margin delta t according to the arrival time deviation amount.
The elevator control method determines a first offset of a first reservation elevator according to positive arrival time deviation amounts in all arrival time deviation amounts of the first reservation elevator, determines a second offset of a second reservation elevator according to negative arrival time deviation amounts in the arrival time deviation amounts of the second reservation elevator, calculates the sum of the first offset and the second offset, and takes the sum as the time allowance delta t.
In general, when a passenger performs a reservation boarding, the deviation between the actual arrival time and the reservation boarding time (the difference obtained by subtracting the reservation boarding time from the actual arrival time) is normally distributed, the mathematical expectation is 0 or the vicinity thereof, the probability of the passenger arriving at the departure floor of the reservation boarding in time and late arrival is substantially equal, of course, the mathematical expectation of the corresponding deviation is negative (i.e., the probability of arriving earlier is greater than the probability of arriving later) for the passenger who likes arriving earlier for individual work, and the mathematical expectation of the corresponding deviation is positive (i.e., the probability of arriving earlier is smaller than the probability of arriving later) for the passenger who pulls the work for individual.
In order to ensure that the physical elevator gets after responding to the first reservation and gets up again to respond to the second reservation and gets up, the worst case that the first reservation and gets up by the passenger is delayed and the second passenger arrives in advance needs to be considered, so when calculating the available moving time for responding to the movement of the elevator car, the time interval between the moment of the first reservation and getting up minus the delay time of the passenger and the moment of the second reservation and getting up minus the moment of the advance time of the passenger needs to be calculated. Here, the passenger arrival time at the first reservation boarding time is the positive arrival time deviation amount of the first reservation boarding, and the passenger arrival time at the second reservation boarding time is the negative arrival time deviation amount of the second reservation boarding.
The current problem is translated into: how to take the passenger delay time for determining the first reservation boarding time and the passenger delay time for determining the second reservation boarding time according to the positive arrival time deviation amount and the negative arrival time deviation amount respectively. Since there are many positive arrival time deviation amounts and negative arrival time deviation amounts of passengers, there is a need to determine a method of calculating positive arrival time deviation amounts and negative arrival time deviation amounts from the positive arrival time deviation amounts and the negative arrival time deviation amounts of passengers, such as: the probability of the average value, the maximum value, the median, or the distribution function of the positive arrival time deviation amounts is set as the positive arrival time deviation amount corresponding to the fractional number of the given probability ρ, and the probability of the average value, the maximum value, the median, or the distribution function of the negative arrival time deviation amounts is set as the negative arrival time deviation amount corresponding to the fractional number of the given probability ρ.
The elevator control method controls the response elevator which can be used for responding to the elevator taking reservation according to the priority according to the following steps:
step T1, determining the specific elevator taking reservation and the priority thereof, and responding elevators which can be used for responding the elevator taking reservation;
step T2, determining the number (n-m) of specific elevator taking reservations needing to be delayed;
step T3, selecting one from all unselected specific elevator taking reservations as a selected specific elevator taking reservation;
step T4, taking all the elevator taking reservations which make the selected specific elevator taking reservations be specific elevator taking reservations or the specific elevator taking reservations due to the selected specific elevator taking reservations as deferral service reservations;
step T5, judging whether the reserved quantity of the deferred service is smaller than the reserved quantity (n-m) of the specific elevator taking which needs deferred service, if yes, returning to the step S3, otherwise, entering into the step S6;
and step T6, allocating respective response elevators for other specific elevator taking reservations except for the deferred service reservation, and providing service for the elevator taking reservations corresponding to the threshold value by the allocated response elevators.
When the elevator control method determines the delayed service reservation, the reserved passenger corresponding to the delayed service reservation is further determined, and response notification information is generated and output.
