Bus arrival time inquiry forecast system based on the data in mobile phone wireless networkAffiliated technical field
The present invention relates to a kind of mass transportation facilities arrival time predicted query system based on the data in mobile phone wireless network.Can make the user land approximate time and the information such as vehicle condition and road conditions that certain website is come the position of enquiring vehicle, arrived certain website by data in mobile phone wireless network or internet whenever and wherever possible.
Background technology
Mass transportation facilities (referring to bus, subway) is the important vehicles of the most of people in urban district.It is generally dispatched a car from starting point according to timetable, and terminal point returns, and has certain stationarity; Simultaneously because the difference of road conditions, vehicle condition also has certain dirigibility.Citizen can select different vehicles trips according to the situation of oneself.
In normal life, the passenger must wait at website, in order to avoid miss because do not know that vehicle accurately arrives the time of certain website.Some passenger is evening a few minutes even tens seconds and miss a regular bus usually, have to wait for next class; Perhaps catch up with the vehicle that has started, cause accidents such as the collision of people's car or personnel's extruding, cause unnecessary loss; Perhaps arrive in platform, just knowing needs to wait for the long period; Just be apprised of vehicle after perhaps having waited for a very long time and on the way break down or traffic jam, the Iterim Change vehicles of having to waste time in vain.
Generally speaking, if numerous citizen can grasp the real-time information of vehicle, these situations will be improved greatly.
Summary of the invention
For make that the passenger knows whenever and wherever possible that mass transportation facilities arrives than correct time, after the present invention fixes, stands and stand erectly according to the mass transportation facilities website and connects running time presents normal distribution according to road conditions rule, vehicle and arrive certain website, the thought that the follow-up website time can estimate according to statistical law, and binding data wireless network (GPRS, Edge or 3G) technology, a kind of real-time mass transportation facilities inquiry system based on data wireless networks is proposed.This system is simple, only the location that can realize bus, subway by simple 3G or GPRS network.The user only needs mobile phone to login this server site particular location, the arrival time of inquiring bus whenever and wherever possible by 3G network, know changeable vehicle condition traffic information in advance, in time adjust plan of travel, select the suitable vehicles, and do not need just to know behind user's in-track platform and also need the stand-by period, need not set up the information indicating screen at website yet.
Technical scheme comprises 3 parts: wireless public transport terminal, background network server and the mobile phone that can surf the Net.
Every car all has a 3G (or GPRS) wireless communication module.When bus or subway during to certain website, wireless communication module will send the relevant information that arrive certain station first to the 3G network server of appointment.After server receives this information, write down this car position and time.Like this, the approximate location of each car just can be recorded in real time in the server.After this system used a period of time, server also just can be added up between departures and the station and meet the time interval of normal distribution, and then just can estimate the vehicle arrival next stop or following required time of several stations.The user uses mobile phone terminal to land this server by 3G network, can find the position that he need take certain road bus, and the time that needs wait.
The invention has the beneficial effects as follows, simple, do not need complicated GPS positioning system, need not add the redundant information prompting screen at website, do not need the user to arrive the public transport platform or enter subway platform after just know the stand-by period, do not need to allow the driver add unnecessary operation the location that can realize bus, subway by simple 3G or GPRS network yet.The user only need login this server particular location and the arrival time of inquiring bus whenever and wherever possible by surfing Internet with cell phone or by the internet.
Embodiment
Each bus is all installed a public transport terminal module.When mass transportation facilities arrived certain website, the driver realized sound broadcast by the button of calling out the stops, and this button causes the public transport terminal sends first " arriving certain station " to the webserver port of appointment by the data in mobile phone wireless network information simultaneously.This information comprises mass transportation facilities identification sign, current time, arrival site name, passengers quantity state, also can comprise the GPS positional information.If serious road conditions or vehicle damage can be sent specific information.
After server receives this information, write down this car position and time.Like this, server just can real time record and the approximate location of upgrading each car.After this system used a period of time, server can be added up the time interval and the rule thereof between departures and the station, thereby can be according to the real time position of car, and certain is stood needed approximate time afterwards to estimate arrival.Certainly, the time of standing in real time and standing by car also can be estimated traffic between departures and the station.
Server is provided with portal website, and the website provides real-time query function.The user is by the internet or use mobile phone to land this server site by the data in mobile phone wireless network, just can find the information of certain bus that he needs easily, as particular location, in the sky of time that certain website need be waited for, the vehicles/full/squeeze situation, traffic along the line, vehicle condition information or the like.
