Intelligent public transportation information inquiry system based on RFID (radio frequency identification) and two-dimensional codes

Abstract

An intelligent public transportation information inquiry system based on RFID (radio frequency identification) and two-dimensional codes is characterized by comprising an IC (integrated circuit) card, on-board readers, a public transportation system network terminal platform, mobile phone public transportation inquiry software (APP) and the two-dimensional codes of bus routes, wherein each on-board reader adopts an embedded system and comprises a controller, a radio frequency module and a GPRS (general packet radio service) module; when the on-board readers read data of the public transportation IC card, the controllers of the readers in the getting on and getting off positions can perform operation of plus one and minus one respectively; information of operation of plus one and minus one each time is processed by the controllers, commands are sent to the GPRS modules, and the data is transmitted to the public transportation system network terminal platform. Therefore, accurate statistics of the number of passengers in the bus can be realized, intelligent bus deployment is realized simultaneously, and the passengers can inquire bus information by scanning the two-dimensional codes or surfing the internet with the mobile phone and more conveniently choose buses to take.

Description

technical field [0001] The invention relates to a bus information query system, in particular to an intelligent bus information query system based on radio frequency identification and two-dimensional codes. Background technique [0002] With the acceleration of people's life rhythm, more and more people need to travel by bus, but the crowding of buses is always the most annoying thing for passengers, especially during commuting time. Most of the current bus population counting systems use the video screen population counting method or the infrared sensor counting method. Although these two methods are more convenient for counting the number of people, there are large errors in the counting. For example, when the infrared sensor counts the number of people, the bus is more crowded. , Passengers also move around, so a passenger can be detected by the infrared sensor twice, three times or even more times. Contents of the invention [0003] The purpose of the present inventi...
