Summary of the invention
The object of the invention is to disclose a kind of bus passenger flow volume with characteristic attribute and calculate the method with statistical study in real time, when operating on the line for bus because of various factors contingent volume of the flow of passengers situation of change, the volume of the flow of passengers special to these identifies and grouping and classifying, carries out real-time calculating and statistical study to bus number in the number of getting on or off the bus and car of any website.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The bus passenger flow volume with characteristic attribute calculates and a statistical analysis technique, and described method comprises the steps:
Bus passenger flow volume calculates:
On bus, the first stop of visitor is defined as initial station, and the station that passenger all gets off is defined as terminal, and second station is defined as current site to the last station of terminal, and the formula that the volume of the flow of passengers calculates is as follows:
Number on a, initial station car: guest's number on number=initial station on the car of initial station
B, second stands to the last station of terminal (can be regarded as current site)
On number on current site car=upper station car, the number+current site number of getting on the bus-current site is got off number;
Guest number=0 under number-terminal on number on c, terminal car=upper station car
Bus sails initial station into and starts upper visitor, and volume of the flow of passengers collector is started working and the volume of the flow of passengers information transmission of collection carried out identifying and judging to processor, and the number of getting on the bus is sent to car-mounted terminal by closing of the door processor; Because being initial station, on car now, number should equal the number of getting on the bus i.e. applicable formula a;
Stand from second, when bus enters any one current site, all likely produce on-board and off-board flow; Passenger follow front upper rear lower rule normally get on or off the bus when, the calculating of the volume of the flow of passengers is suitable for formula b;
Because situations different as follows occurs in the impact of various factors:
A, to block up the period, the situation that passenger gets off from entrance door and gets on the bus from exit door can occur; The volume of the flow of passengers processor of forward and backward door sends in the data of car-mounted terminal the number of getting on the bus and number of getting off that contain forward and backward door; Therefore on current site car, the computing formula (i.e. formula b) of number can be evolved into:
1., get on the bus number in the number of getting on the bus+back door, the current site number of getting on the bus=Qianmen
2., get off number in the number of getting off+back door, the current site number of getting off=Qianmen

Embodiment
The present invention does not make a search in volume of the flow of passengers acquisition and processing, but directly applies other people achievement in research, present invention employs " YWA-GKM bus passenger flow volume acquisition and processing device " that Wenzhou, Zhejiang Province hundred million leads to the production of automation equipment company limited.This is the current domestic product uniquely obtaining commercial applications on bus.The requirement according to the invention of its precision.
Website alleged by the present invention does not refer to platform ordinary meaning with physical aspect, but a region being intermediate value with certain platform with longitude and latitude.In this region, no matter car door has the number of getting on or off the bus of N switch and passenger, all should regard the volume of the flow of passengers of this website as.In like manner, leave the boarding and alighting that this region occurs, then should collect next website and add up.
Eigenwert alleged by the present invention means " time, platform title, vehicle license (license plate number), line name, upstream or downstream direction ".The most essential characteristic of the real-time volume of the flow of passengers is exactly its time point, and different time points reflects the different volumes of the flow of passengers.The volume of the flow of passengers that so there is no time point is skimble-skamble.The volume of the flow of passengers is again closely be connected with concrete website, and the volume of the flow of passengers of different website is different.The volume of the flow of passengers shows as again a certain bus in certain time point number in the number of getting on or off the bus and car of certain website.Bus is that order is stopped and sails out of the website pre-set on the operation route of regulation simultaneously, and therefore the volume of the flow of passengers reflects again the volume of the flow of passengers change of certain public bus network.Article one, no matter it is broken line traveling or loop wire traveling to public bus network, has dividing of uplink and downlink.The website of same title represents the different travel direction of bus in uplink with downgoing line, and therefore the volume of the flow of passengers has directivity.In sum, we are defined as the real-time volume of the flow of passengers: " any bus at any time, the volume of the flow of passengers that occurs of any direction any one website in any circuit." as can be seen here, if no matter asynchronously possess this five eigenwerts by the real-time volume of the flow of passengers which kind of method gathers, its volume of the flow of passengers drawn does not possess uniqueness.
No matter be uplink or downgoing line, the present invention is defined as initial station the first stop of visitor on bus, and the station that passenger all gets off is defined as terminal, and second station is defined as current site to the last station of terminal.Then the formula of volume of the flow of passengers calculating is as follows:
Number on a, initial station car: guest's number on number=initial station on the car of initial station
B, second stands to the last station of terminal (can be regarded as current site)
On number on current site car=upper station car, the number+current site number of getting on the bus-current site is got off number
Guest number=0 under number-terminal on number on c, terminal car=upper station car
The concrete computation process of the volume of the flow of passengers and method
Installation requirement according to manufacturer respectively installs a set of volume of the flow of passengers acquisition and processing device at bus front/rear door, and adopt magnetic flux trigger switch gate signal, door opens volume of the flow of passengers collector and processor is started working.485 or CAN and car-mounted terminal are adopted to carry out communication.After closing of the door, the volume of the flow of passengers information after process is sent to car-mounted terminal by volume of the flow of passengers processor automatically, and after receiving the response instruction of car-mounted terminal, volume of the flow of passengers processor carries out resetting and proceeding to dormant state.
Bus sails initial station into and starts upper visitor, and volume of the flow of passengers collector is started working and the volume of the flow of passengers information transmission of collection carried out identifying and judging to processor, and the number of getting on the bus is sent to car-mounted terminal by closing of the door processor.Because being initial station, on car now, number should equal the number of getting on the bus i.e. applicable formula a.
Stand from second, when bus enters any one current site, all likely produce on-board and off-board flow.Passenger follow front upper rear lower rule normally get on or off the bus when, the calculating of the volume of the flow of passengers is suitable for formula b.
Because situations different as follows often occurs in the impact of various factors:
A, to block up the period, the situation that passenger gets off from entrance door and gets on the bus from exit door can occur.Under volume of the flow of passengers collector and processor have correctly identified the prerequisite also judged, the volume of the flow of passengers processor of forward and backward door has sent in the data of car-mounted terminal the number of getting on the bus and number of getting off that contain forward and backward door.Therefore on current site car, the computing formula (i.e. formula b) of number can be evolved into:
1., get on the bus number in the number of getting on the bus+back door, the current site number of getting on the bus=Qianmen
2., get off number in the number of getting off+back door, the current site number of getting off=Qianmen
3. number on, number on current site car=upper station car+(number of getting on the bus+back door, Qianmen get on the bus number)-(number of getting off+back door, Qianmen get off number)
Car-mounted terminal carries out the calculating of the volume of the flow of passengers according to evolution formula.
B, to block up the period, when many buses are queued up and entered the station, the situation of bus multiple switching door on-board and off-board can occur.Longitude and latitude when bus is in the on-board and off-board of multiple switching door all drops within the scope of the site zone of our definition, and its all on-board and off-board flow is all included into current site and calculates; Longitude and latitude when bus is in the on-board and off-board of multiple switching door, what have drops in current site regional extent, have drop on regional extent outer time, the volume of the flow of passengers is at the regional level included into current site and calculates, and next website that is included into outside regional extent calculates.After repeatedly volume of the flow of passengers data in the region received first gather by evolution formula " number of getting on the bus+back door, the current site number of getting on the bus=Qianmen get on the bus number " and " number of getting off+back door, the current site number of getting off=Qianmen get off number " by car-mounted terminal, then calculate by evolution formula " number on number=upper station car on current site car+(number of getting on the bus+back door, Qianmen get on the bus number)-(number of getting off+back door, Qianmen get off number) ".Upload the switch gate number of times of this website simultaneously.
C, when bus travel on the line because of in car-mounted terminal gps signal occur drift or antenna failure cause positioning data of vehicles inaccurate time, car-mounted terminal is temporary after the volume of the flow of passengers data received 1. and 2. being calculated by the evolution formula of formula b, during the longitude and latitude correct to next website to be obtained, add up to calculating in the lump with the volume of the flow of passengers data of this website.Computing formula is still formula b and evolution formula thereof.
