Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings by way of specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In one embodiment, as shown in fig. 1, there is provided a dispatching method of a linked elevator, comprising the steps of:
s110, basic information of the target area is obtained, and the basic information comprises elevator configuration information and building attribute information.
Specifically, basic information of a target area is obtained, wherein the target area refers to an area needing to adjust an elevator dispatching method and includes, but is not limited to, residential districts and commercial buildings, the basic information includes elevator configuration information and building attribute information, wherein the elevator configuration information specifically includes the number N of elevators and the maximum constant speed V of elevator operationmaxThe number of people with the maximum load of the elevator PmaxElevator starting acceleration astartThe static acceleration a of the elevatorstopElevator maximum load MmaxMass M of elevator and real-load mass M of elevator (M is less than or equal to M)max) And residence response time TstayAnd the like, and the building attribute information refers to other situations of the building besides the elevator, such as building resident situations, building buildings of the building and the like, wherein the building resident situations comprise: average number of stories per floor QeAverage number of people per household PeThe total number of people P ═ Qe*Pe(ii) a Building conditions include: minimum floor distance S and maximum floor number nfThe number n of target floorsnThe number n of floor intervals is equal to n1-n2(n1<nf) Maximum floor distance Smax＝S*nfAnd an elevator path Ln＝n*S。
S120, receiving a dispatching instruction of a user, wherein the dispatching instruction comprises target floor information and target running direction information of the user.
Specifically, when a user floor sends a dispatching instruction, namely a user presses an elevator, the dispatching instruction of the user is received, wherein the dispatching instruction comprises a floor of a user key, namely target floor information required to be reached by the elevator, and the selected uplink or downlink is the target running direction information of the elevator.
In one embodiment, before step S120, the method further includes: and dividing the elevator use time period into a low valley period, a common period and a peak period according to preset information. Specifically, the use probability of the elevator is not evenly distributed, and the use time of the elevator is divided into a low valley period, a common period and a peak period according to the actual situation; the valley period is generally set as: 22: 00-6: 00; the data can be formulated according to night patrol time of community security, the elevator scheduling problem is not considered in the time period, and the use experience cannot be influenced when the data is the same as the scheduling mode of other two periods. While peak settings are typically: 7: 00-9: 00, 16: 00-20: 00; the data is formulated according to national subway and highway peak periods published by the traffic bureau. For the normal period setting then: the time periods other than the valley period and the peak period are normal periods.
In one embodiment, after step S120, the method further includes: when the elevator use time period is in a peak period, the elevator needs to be dispatched to the highest floor or the lowest floor with dispatching instructions. Specifically, according to a traditional peak scheduling mode, the uplink and the downlink are not distinguished, and if the bearing weight reaches the upper limit, the elevator only moves to a target area reached by a user in the current elevator; therefore, when the peak scheduling mode is to ensure that all floors can be seated to the elevators, all the elevators need to be issued to the uppermost layer or the lowermost layer with scheduling requirements; and the rest can be scheduled according to the ordinary trip.
S130 judges whether there is an empty elevator.
Specifically, it is first determined whether there is an empty elevator, i.e., an elevator that is not running, based on the information obtained in step S120.
And S140, if so, judging whether a co-current elevator exists according to the target running direction information:
S140A, if the elevator in the same row exists, respectively calculating expected time values of the idle elevator and the elevator in the same row reaching the target floor, and selecting the elevator with smaller expected time value as the target elevator to dispatch to;
and S140B, if no elevator in the same row exists, directly selecting the elevator with the minimum expected time value as the target elevator for dispatching.
Specifically, the average probability is used for presetting that the use frequency of the elevator is g, g represents that the average probability of the average use times of the elevator per day of each person is preset for the number of users in each floor to be equal, and the non-common use single path of the elevator per day is as follows:
Ln＝n*S*Qe*Pe*g
the elevator operation algorithm is as follows:
Figure BDA0002585084910000051
the running time of the elevator is as follows:
T＝t1+t2+t
probability of elevator being operated:
Figure BDA0002585084910000052
the probability of waiting for the elevator simultaneously then turns into traditional probability, and two people wait to elevator probability of a shift simultaneously promptly:
Figure BDA0002585084910000053
p (n) ═ P (two classes equal shift)n
Because the number of people in different shifts reaches the mutual exclusion event, the probability can be calculated by using the Bernoulli formula
According to bernoulli profile formula:
Figure BDA0002585084910000054
the probability of several people, i.e. a certain person, counting the same shift can be calculated, and the actual application must be such that n < P because the elevator load capacity is fixed.
When the elevator runs, the buttons in the same direction block again, and due to the property of the elevator, the elevator can be intercepted in the ascending process, generally in the descending process with a very small probability.
The probability algorithm is the same as the average probability of use, then:
p (n) ═ P (interception probability)n
But as the lower the floor is, the lower the probability of a downlink collision is, so that:
Figure BDA0002585084910000061
therefore, if there is an idle elevator, it is judged whether there is a co-traveling elevator, and if there is a co-traveling elevator, a co-traveling elevator path L is calculatednN × S, the expected downlink time is:
Figure BDA0002585084910000062
i.e., the down stream expectation time is equal to the run time plus the intercept hold time, where T is the run time,
calculating the idle elevator down time T2:
If T2<TPractice ofCalling out an idle elevator for going; if T2>TPractice ofAnd waiting for the elevator in the same row to go forward.
If there are no co-traveling elevators, then a non-co-traveling elevator path is calculated:
Ln＝(n2-n1)*S+n*S
the downlink expected time is as follows:
Tpractice of＝T+Tstay
Calculating the idle elevator down time T2:
If T2<TPractice ofCalling out an idle elevator for going; if T2>TPractice ofAnd waiting for the non-co-traveling elevator to go forward.
In one embodiment, the desired time value to reach the target floor is specifically: and obtaining the running time and the estimated residence time of the elevator according to the basic information, and obtaining the expected time value of the elevator reaching the target floor according to the running time and the estimated residence time of the elevator. Specifically, the expected time value is based on the sum of the running time of the elevator and the residence time in the dispatching way, and the running time of the elevator can be directly obtained according to basic information, but the residence time in the dispatching way is estimated through a Bernoulli model, which is specifically described in the steps S140, S140A and S140B.
In one embodiment, if there is no co-current elevator, the step S140 directly selects the elevator with the minimum expected time value as the target elevator to dispatch to specifically: and if no elevator in the same row exists, respectively calculating expected time values of the idle elevator and the elevator in the different row reaching the target floor, and selecting the elevator with the smaller expected time value as the target elevator to dispatch to the destination. Specifically, when the elevator in the same row does not exist, the calculation of reaching the target floor is directly carried out on the elevator in the different row and the idle elevator respectively, so that the expected time of reaching the target floor can be obtained, and the elevator with shorter expected time is selected as the target elevator and is transferred to the target floor.
And S150, if no idle elevator exists, respectively calculating expected time values of all elevators reaching the target floor, and selecting the elevator with the minimum expected time value as the target elevator to dispatch to.
Specifically, all elevator paths are calculated: l isnN × S, the expected downlink time is:
Figure BDA0002585084910000071
when no idle elevator exists, the expected time value of each elevator reaching the target floor needs to be directly calculated, and then the elevator corresponding to the minimum expected time value is selected as the target elevator and dispatched to the target floor.
In the embodiment, the elevator dispatching is carried out according to the basic information of the target area and the dispatching instruction of the user and according to the fact whether the idle elevator exists or not, the elevator with shorter expected time is selected to be dispatched to the target elevator, the elevator is in the valley period, the ordinary period and the peak period according to the basic use condition, and the elevator is dispatched to the highest layer or the lowest layer with the dispatching instruction aiming at the peak period, so that the most appropriate elevator dispatching method based on the actual condition of the target area is realized, the waiting time of the user is reduced, and the user experience and the elevator operation efficiency are improved.
