Description
Technical field
The present invention relates to intelligent transportation and mobile terminal application, particularly relate to a kind of system and method judging the bus degree of crowding based on base station.
Background technology
Intelligent transportation (ITS, IntelligentTransportationSystem) is the one of technology of Internet of things, is also the developing direction of future transportation system.The fusion of the infotech of advanced person, data communication transmission technology, Electronic transducer technology, control technology and computer technology is applied to traffic control system by it, can supervise traffic, avoid the wasting of resources, ensures traffic safety, improves conevying efficiency.And in intelligent transportation system, real-time statistics is carried out to the volume of the flow of passengers on bus, for acquisition bus state, reasonable arrangement receives departure plan, increases work efficiency to have great importance with service quality.
For the problem of guest flow statistics on bus, current technology has:
(1) based on the disposal route of computer vision: the method obtains image or video information mainly through video surveillance, then uses the method for image procossing to add up number on bus.Statistical method mainly comprises the counting to human body or the resolution to the number of people counts.Although the method can count the volume of the flow of passengers to a certain extent, carry out Head recognition when passenger is kept in motion on crowded to capacity on bus or car or human bioequivalence counting can produce very large error, and real-time is not good;
(2) installing the induction of certain sensing element at car door place through the human body signal of car door changes into electric signal and counts, and opens the light etc. as utilized pressure transducer, infrared sensor of the human body, infrared electro.The method defect is a lot, as two people step on a sensor or simultaneously by being mistaken for a people during infrared sensor simultaneously; Mistake can be sentenced when human body is got on or off the bus; Can fail to judge when human body strides across sensor; Have during weight and will judge by accident, and sensor process loaded on the vehicle is jolted and to be jammed on etc. and can cause sensor degradation, and counting is made a mistake;
(3) bus IC card is used to add up.The method obtains number on car indirectly mainly through the statistics number of times that passenger swipes the card of getting on the bus.The method obtains major defect and is that the popularity of mass transit card and usage degree cause very large impact to counting, and intelligence degree is lower;
(4) based on the bus platform calling scheme of GPRS wireless network.The mobile terminal that the program is mainly had by passenger opens the online of GPRS flow, and realizes the statistics of passenger flow in public transport during passenger loading in the information of platform place collection touch.The shortcoming of this kind of scheme is: along with the development of wireless network, and few people understand usage data flow to surf the Net; And passenger will often click touch-screen at platform place and lose time very much.
