The service request is exactly that passenger (can be landing button, or be purpose building in stop by operating device
Layer building floor choosing device can also be any equipment that can issue call request such as mobile phone) it calls elevator, elevator is required to come to service
Behavior, it is generally the case that this service request can generate a corresponding calling signal (or referred to as chauffeur signal).?
In existing multiple lift control system, which can be sent to team control unit by the communication unit of elevator.
The present invention is based in the multiple lift control system of multiple agent competitive way, each elevator control system be one from
Main intelligent body, intelligent body is by being passenger services after competitive way acquisition Service Privileges.Under normal circumstances, passenger sends out in stop
Calling signal out is sent to an elevator being connected with operating device (i.e. calling device).In the present invention, on each stop
Chauffeur device be connected with an elevator control system, obtain the elevator control system of calling signal according to scheduled agreement, packet
Calling signal is filled, the other elevator control systems for making information on bidding and being sent in collaboration range, each elevator control system is received
It responds after to information on bidding, submits a tender for the calling signal, service power is finally obtained by optimal intelligent body of bidding
Limit, provides service for passenger.
Each intelligent body includes user interface elements (i.e. UI unit), competitive bidding unit, communication unit, control unit, such as Fig. 1
It is shown, wherein：
User interface elements are mainly mentioned including receiving the calling signal of passenger, carrying out service for interacting with passenger
Show and (is its service by showing screen informing passenger by which elevator, the state of elevator of service, such as position, direction are provided)
Deng the user interface elements are directly connected to calling device in landing calls device or carriage by wired mode or wireless mode
And service prompts device (such as display screen etc.)；
Communication unit, for carrying out information transmitting with the other intelligent bodies cooperateed in range；
Competitive bidding unit, for generating all information in tendering process, including information on bidding, bid information, tender price
Deng, while sending communication unit to by user interface elements and carrying out competitive bidding with the other intelligent bodies cooperateed in range；
Control unit is exactly traditional electric life controller, is service execution unit, when as intelligent body certain
After elevator control system is submitted a tender successfully, the control unit in the intelligent body forms executive plan according to calling form and executes service
To provide required service for passenger.
Here user interface elements are on logical meaning, including receive operating member and information alert component, wherein
Receive operating member include traditional landing button, car button and novel application program of mobile phone (APP), the POS even
It is the device that bio-identification terminal etc. can inherently export calling signal, information alert component is that elevator service information is anti-
It feeds the device of user, including display screen and mobile phone screen etc. in traditional stop direction and floor indicator, carriage.With
Family boundary element receives passenger operation, generates calling signal to subsequent cell, during subsequent cell carries out competitive bidding, user
Boundary element shows some current selections services or other humanized information, show competitive bidding result to multiplying after the generation of competitive bidding result
Visitor.For example, passenger issues calling signal and when not generating competitive bidding result, user interface elements can show " you select be before
Toward the building N, sending suitable elevator, please wait a moment " information, user interface elements can show elevator after competitive bidding result generates
Information on services " the m elevator serviced for you is being come, and the waiting of the side m please be arrived ".
As shown in Figure 1, the user interface elements and communication unit carry out information bidirectional transmission, the competitive bidding unit and use
Family boundary element carries out information bidirectional transmission, and the competitive bidding unit carries out information transmission to control unit.
In the present invention, multiple elevators of collaborative work are referred to as elevator group, accordingly, multiple elevator control system compositions
The communication modes of multiple lift control system, multiple lift control system can take many forms, as long as meeting all elevator control systems
Within a specified time complete tendering process.For example, can physically use wired connection (can for bus-type, grid type,
Star-like equal various structures), it can also be using wireless connection；Form of communication can be event-driven, or polling mode, this
Field technical staff can carry out equipment according to actual needs.Under normal conditions, passenger starts in stop operation call button, is
System needs that result is fed back to passenger in a few seconds, and Fig. 2 show bus-type networking architecture.
Multiple lift control system carries out response processing and feedback result for the calling signal of passenger, and main includes submitting a tender
Journey, acceptance of the bid implementation procedure further relate to re-bid in above process, service the abnormal conditions processing such as undertaking person's transmission failure.
It elaborates below for each process.
In the present invention, the competitive bidding unit of each intelligent body (can be thrown by two factor triggerings into working condition
Mark process), a factor is that passenger is believed by chauffeur (or reservation) device sending call (or reservation) being connected with the intelligent body
Number, another factor is then that intelligent body detects there is new information on bidding on network by communication unit, related procedure such as Fig. 3 institute
Show.
Intelligent body is by the detailed process that above-mentioned first factor enters working condition：Passenger passes through the chauffeur in stop
Device or device for displaying predetermined calling (or reservation) elevator, such as utilize the operation button or floor selector of stop or cell phone application etc., passenger
Call operation generate calling signal and give the use of the corresponding intelligent body of chauffeur device by communication unit real-time transmission
Family boundary element.User interface elements are connected to after calling signal and are made into the service request information of standard (i.e. according to the agreement of regulation
Pack calling signal), and the service request information is sent to the competitive bidding unit of the intelligent body.Competitive bidding unit is connected to service request
After information, calculate tender price for this service request information and generate bidding information, then by bidding information via with
Family boundary element hands to communication unit.After communication unit is connected to bidding information, according to the agreement arranged in advance by bidding
Information is sent to network (network where the intelligent body of all collaborative works).
Intelligent body enters working condition with by calling triggering by the process that above-mentioned second factor enters working condition
Process is similar, the difference is that the communication unit moment of intelligent body monitors network where it, after receiving information on bidding just
Send competitive bidding unit to, subsequent process is identical as calling triggering, i.e., competitive bidding unit calculates tender price, generates bid information simultaneously
Communication unit is sent to through user interface elements and is issued by communication unit.Communication unit monitors network, and mainly there are two functions：
(1) it if there is data on network, receives and sends subsequent corresponding units processing to；(2) it obtains network sending permission and sends number
According to.If networking, using agreements such as general TCP, collision avoidance is default feature, also it is referred to realization and conflicts back
Function is kept away, this part has been the existing mature technology of network communication, and it will not be described in detail here.
Bidding packet contains bidding number, sender, call property (departure floor, just/back side, direction, purpose building
Layer, special requirement), current best price, that is, bidder number, current candidate price and bidder's number, as shown in table 1, but simultaneously
Not limited to this, those skilled in the art, which can according to need, increases or decreases relevant information.
1 bidding message structure of table
The bid of one intelligent body is from the whole process for being connected to information on bidding to the tender price for generating itself, i.e. Fig. 3
The middle link for generating bid information.No matter intelligent body is triggered by which factor and enters working condition, and bid is recruited from discovery
Mark information starts, the difference is that, the competitive bidding unit of intelligent body is entered the specific mistake of working condition by first factor triggering
Journey is to be made into information on bidding after itself being connected to service request information, automatically into bid link, and the competitive bidding unit of intelligent body by
The detailed process that second factor triggering enters working condition is that discovery has information on bidding on network, hence into bid ring
Section.Specific steps are as shown in figure 4, be described as follows：
The first step, after the communication unit of some intelligent body receives bidding information and is sent to competitive bidding unit, competitive bidding
Whether unit judges itself have service ability to the information on bidding, that is, judge whether itself meets requirement of invitation for bid, if met,
Then enter second step, otherwise sets tender price to arrange worst price, into the 7th step；
Second step, competitive bidding unit generate tender price according to the tender price algorithm of setting according to self-condition；
Third step, competitive bidding unit by the tender price of generation compared with the current best price in bidding information, if
Better than current best price, then enter the 4th step, otherwise enters the 5th step；
4th step, competitive bidding unit replaces current best price and best price bidder, into the 7th step；
5th step, competitive bidding unit by the tender price of generation compared with the current candidate price in bidding information, if
Better than current candidate price, then enter the 6th step；
6th step, competitive bidding unit replace current candidate price and candidate price bidder, into the 7th step；
7th step, competitive bidding unit updates the bidding information including bidder's list, by bidding information via user circle
Face unit sends communication unit to, network where being sent to the bidding information of the intelligent body by communication unit.In order to avoid
The bid of multiple intelligent bodies clashes in a network, can use the network protocol such as TCP etc. of standard, network conflict is by bottom
Agreement solves automatically, if without network protocol, it can be by being accessed again after generating random number latency period
Mode waits interval different, can avoid network conflict because the random number that different intelligent body obtains can be different,
Above-mentioned technology belongs to the mature means of network communication, therefore is not described in detail here.
In tendering process, the competitive bidding unit of each intelligent body judges whether tendering process should terminate.In the present invention
In, tendering process can be terminated by two conditions, and first is that all intelligent bodies in cooperateing with range have been submitted a tender, and second is
Time interval between current time and bid time started has exceeded the longest bid time of setting.
When each intelligent body finds that this bid meets termination condition, the bid state in bidding information is set into bid knot
Beam, and all intelligent bodies being broadcast in collaboration range, process is as shown in figure 5, specific as follows：
The first step, competitive bidding unit compares bidder's list with the members list for being stored in competitive bidding unit, if institute
There is intelligent body to submit a tender, then enter the 4th step, otherwise enters second step；
Second step, competitive bidding unit calculate bid pass through the time, i.e., current time and bid the time started between time between
Every；
Third step, whether the bid of competitive bidding unit judges exceeds the longest bid time by the time, if it is, into the 4th
Step is sent to place network after being otherwise made into bid information；
4th step, the bid state in bidding information is set bid end mark by competitive bidding unit, and bid is terminated letter
Breath is sent to communication unit through user interface elements, is sent to all intelligent bodies in collaboration range by communication unit.
When the competitive bidding unit of some intelligent body discovery bid termination condition is set up, generating bid ending message (is exactly to recruit
The bid state of mark information is set bid and is terminated) and it is sent to each on-line intelligence body in collaboration range, in bidding information
The bidder of current best price is winning bidder, provides service by winning bidder for passenger.When the communication unit of some intelligent body
After receiving bid ending message, the bid ending message is sent to competitive bidding unit through user interface elements, it is true by competitive bidding unit
Recognize whether itself is winning bidder's (i.e. whether competitive bidding unit confirmation best price bidder number is oneself number), if it is acceptance of the bid
Acceptance of the bid information is then notified control unit by person, competitive bidding unit, while being generated and being accepted information and be sent to each in collaboration range
A on-line intelligence body；If itself not being winning bidder, further confirm that whether be candidate winning bidder, if it is, start timing,
It waits winning bidder to issue and accepts information, if the competitive bidding unit of the intelligent body within a specified time fails to receive the undertaking of winning bidder
Information oneself will then be switched to winning bidder and acceptance of the bid information notified control unit, while issuing undertaking information, and be expressly recited
Service (the candidate price person for being recorded in information on bidding) is accepted by candidate winning bidder.
Control unit is connected to after acceptance of the bid information, is formed executive plan and is executed service.All intelligent bodies get the bid this
Information is charged in held service registration table, which is held and managed by competitive bidding unit, is used to record elevator
The information such as all bidding information, final undertaking person in group control system.
After an intelligent body completes primary service, control unit notifies competitive bidding unit, has been serviced by the generation of competitive bidding unit
All intelligent bodies are sent at information and through user interface elements and communication unit, and all intelligent bodies are connected to the clothes after the information
Business deletes out of service registration table and moves on to historical record (historical record is an independent region in competitive bidding unit, is deposited
Put each information on bidding) it saves, it mainly includes the relevant data of service process that information is completed in service, is such as connected to information on bidding and arrives
Service starts time used, the time for providing service etc..
In tendering process, some abnormal conditions can occur with not can avoid, such as re-bid, service undertaking person's generation event
Barrier etc..
Wherein, in the process of running, the competitive bidding unit of intelligent body is expected to according to specific period traverse service registration form, searching
The demand for services rebid.When finding the information on bidding that can be rebid in service registration table, competitive bidding unit can be given birth to
At bid information again, and via user interface elements requirement communication unit, to the service, currently undertaking person sends bid information again.
After intelligent body communication unit as current undertaking person is connected to bid information again, competitive bidding unit is sent to through user interface elements,
Competitive bidding unit reappraises the service, if tender price of the tender price still than bidder again is excellent, then result is
It maintains the statusquo, otherwise bidder gets the bid again, and competitive bidding unit generates again bid information according to result and sends bidder again to.It submits a tender again
If itself winning after person is connected to bid information again, it is published to all intelligent bodies (same way is announced with bid result), institute
There is intelligent body to update service registration table.
When the acceptance of the bid of some intelligent body but can not fulfil accepted service, fault message is generated by competitive bidding unit and is passed through
Network where user interface elements and communication unit are published to, the fault message include failure person's number and fault attribute, each intelligence
Can the communication unit of body receive and inform that competitive bidding unit, competitive bidding unit check service registration through user interface elements after fault message
Table is revised using intelligent fault bodies all in table as the record of winning bidder, is replaced with candidate price and candidate price bidder
For winning bidder and tender price, candidate's field information is remained unchanged, that is, the winning bidder of these services readjusted after modifying
As being with candidate.Newly elected winning bidder (i.e. former candidate) is by the Service Notification to control unit, control unit column
Enter service program and executes service.In addition, being not suitable for when intelligent body finds to have existed in the service oneself accepted by oneself
When providing, the information of bidding again can be also issued, and process is identical as normal bidding.
In aforementioned tendering process, intelligent body is for the current shape that the tender price of some service request is according to intelligent body
What the characteristics of state and the service was calculated according to certain tender price algorithm, calculated result reflects that the intelligent body provides clothes
The expection of the quality of business.In general, tender price, there are two types of situation, the first is waiting time class index, at this time the value it is more low more
It is good, such as passenger's average latency during riding time, elevator are run, it is also possible to these services or waiting time index
Simple function；Second is that intelligent body provides the remuneration of service acquisition, and the higher the better for the value at this time, in this case, is submitting a tender
The high side of remuneration wins in the process, some indirect indexes is generallyd use, when encouragement intelligent body receives orders more and order is completed
Between if lower than the system option adjusted duration (all intelligent body draws or the history of oneself average) having now known, by difference section
With the product of the service sum of undertaking and according to some proportion coefficient as being awarded to intelligent body.
The algorithm for calculating tender price can be some explicit function calculating process, or neural network (including
Deep neural network) etc. computation models.As a kind of specific implementation, the hair application No. is 201310080795.7 can refer to
The scheme that bright patent application is announced.
On the basis of above-mentioned multiple lift control system, the intelligent behavior of intelligent body is more excellent other than aforementioned bidding behavior
A feature be that can learn tendering process and service process, constantly improve the computing capability of oneself tender price.Therefore, intelligence
Can body further include self study unit, the self study unit can according to tendering process and execute service process in all data into
Row self study and the competitive bidding mode for improving competitive bidding unit, as shown in Figure 1, competitive bidding unit and control unit are jointly to self study unit
Carry out information transmission.
In the present invention, the self study unit of each intelligent body is by the way of enhancing study, according to bid data kimonos
Business result is independently learnt.During self study, there are two states, i.e. idle state and service state for intelligent body.It is idle
State refers to that the current operational plan of intelligent body does not have any unfinished service request and remains static, and belongs to waiting task
State.There are unfinished service request or the service not completed to ask in intelligent body operational plan although service state refers to
It asks, but is carrying out in some service process.Enter service state from idle state, and completes all service programs again
Process into idle state is known as a scene (episode).After each scene, the self study unit of intelligent body
Self study all is carried out to the data during scene.
Intelligent body carries out the prediction data of the tender price when target of self study is bid and reality is completed in final service
Data are consistent as far as possible, i.e., the service quality predicted when making and submit a tender by self study is more and more accurate, best when submitting a tender in this way
The best service that tender price is to.
Self study result in one scene of intelligent body is temporarily stored in inside self study unit, is not updated usually and is submitted a tender at once
Calculation of price rule.After the scene of intelligent body experience reach certain amount (such as 50) afterwards the unified throwing for updating all intelligent bodies
The tender price of marked price lattice computation rule, i.e., all intelligent bodies of result synchronized update learnt with an intelligent body calculates rule
Then.When an intelligent body self study unit through specifying number scene self study after, will be with broadcast mode (by self study list
Member issues, and successively passes through competitive bidding unit, user interface elements, is finally broadcasted by communication unit to place network) to issue study logical
Know to the other intelligent bodies cooperateed in range, prepare publication learning outcome, intelligent body has fed back publisher after receiving study notice
Through preparing to receive data, after publisher issues learning outcome, each intelligent body updates oneself tender price computation rule in group, updates
Publisher is fed back to as a result, publisher records successfully regenerator's list and version after success.If some intelligent body fails
Update is also not related, is updated to most because the update of learning outcome using old parameter is directly covered, can skip the intermediate stage
New result.
Study, which updates, each time unique version number, for example, version number is 0 at the beginning of system, updates every time
Add 1.According to existing record when issuing study notice when an intelligent body prepares publication learning outcome, automatically generate new
Version number, and be published to all members in group, each member updates internal record, maintains latest edition number.No matter learn
As a result it updates and whether succeeds, version number once announces and cannot cancel.If issuing more new version is lower than current latest edition,
It then updates and is ignored.
Although in the above description, all intelligent bodies in range is cooperateed with to update tender price computation rule jointly,
The present invention is not limited thereto, and intelligent body can also update alone.In addition, all numbers that although competitive bidding unit generates in the present invention
It is believed that breath is all sent to communication unit by user interface elements, then issued by communication unit, but those skilled in the art
Member can easily improve according to above-mentioned principle, and the information for generating competitive bidding unit is directly carried out by communication unit
Publication, without being subjected to user interface elements, illustrates hereby.

The mode of formula, therefore multiple lift control system is no longer dependent on single team control unit, avoiding team control unit and breaking down causes
Team control failure team control mode is changed to independent individual competition task from traffic control under limited resources in essence
It cooperates, the scalability of system is significantly promoted.In the prior art, the control number of units of group control system is largely determined by conduct
The hardware interface number and computing capability of team control unit, and in technical solution of the present invention, it, can be any as long as network insertion allows
Increase group member, the calculated load of each member does not have any increase.
The present invention is cooperated in the form of mode of bid competitive service permission, meanwhile, in order to solve some special rule
Lattice calling or special services requirement, set bid qualification system, and the intelligent body for only meeting requirement of invitation for bid can submit a tender, side
Just the realization of special requirement；Mark result is no longer rely on single team control unit and carries out service distribution, but each intelligent body is according to association
View is decided in its sole discretion, and the acceptance of the bid undertaking person for obtaining Service Privileges announces result according to agreement.
Meanwhile each intelligent body of the invention has the rule for redefining undertaking person for issuable abnormal conditions,
The mechanism for carrying out secondary competition at any time has been introduced simultaneously, can have been replaced for some unsuitable undertaking persons according to condition variation
The mechanism changed, so that group control system has mechanism for correcting errors；Due to using multiple agent competitive way, the independence of each intelligent body
Self study is easily achieved, and can independently can be learnt according to oneself operational process, and be updated, so that successive optimization makes
Intended result and actual result when bid are more nearly.
The present invention, so no longer needing additional team control unit, is saved and is set due to eliminating focus control mode
Standby cost, decreases fault point；Meanwhile service is scattered in each elevator, running frequency is more dispersed, will not frequently replace team control
Equipment is economically more advantageous.
