Abstract
The invention discloses a bus positioning system based on the UHF RFID technology. The bus positioning system is composed of an RFID tag, a reader-writer and a background system. An identification code is written in the RFID tag, and the geographical location information of the identification code and the geographical location information of the RFID tag are bound in the background system and are in one-to-one correspondence. The RFID tag is in communication with the reader-writer through RFID signals, and the reader-writer reads information in the RFID tag. The reader-writer is connected with the background system through wireless transmission and transmits the identified RFID tag information to the background system, and the background system determines the position of a current bus by analyzing the RFID tag information.
Description
Technical field
The present invention relates to intelligent transportation field, be specifically related to a kind of bus positioning system based on UHF RFID technique.
Background technology
Along with motor vehicles are increasing, the problems such as the management of vehicle and the operation security of vehicle highlight day by day, how to solve the focus that problems has become informatization concern.Increasing city starts to carry out public traffic in priority policy to alleviate traffic pressure, and people expect to have a kind of technology, can understand the positional information of public transit vehicle in real time and provide place information inquiry and platform forecast for it.GPS (GPS) is the vehicle positioning technology be most widely used at present, and the Beidou satellite navigation system of China have also been obtained certain development.But the application of GPS and Beidou satellite navigation system exists some problems, as inaccurate in located, positioning error at 10-20 rice, if be subject to the many factors such as such as weather, sometimes also can be larger; Secondly, the covering problem of GPS and Beidou satellite navigation system causes the existence receiving blind area; GPS and Beidou satellite navigation system all in conjunction with map work, usually because the renewal of map causes the maximum error of locating and guiding not in time.
Summary of the invention
The invention provides a kind of bus positioning system based on UHF RFID technique, current bus location Problems existing can be overcome, there is the advantage that precision is high, cost is low.
Technical scheme provided by the invention is that a kind of bus positioning system based on UHF RFID technique is made up of electronic tag, read write line and background system, with identification code in electronic tag, electronic tag is communicated by radio frequency signal with read write line, the information in read write line reading electronic labels; Read write line is connected with background system by wireless transmission, and read write line is sent to background system the electronic labeling information recognized, and background system determines the position of current bus by analytical electron label information.
Described electronic tag is UHF ultrahigh-frequency passive electronic tag, electronic tag and read write line air interface protocol standard are GB GBT29768-2013 " infotech radio-frequency (RF) identification 800-900MHz air interface protocol ", and ISO 18000-6C/EPC Global C1 Gen2 standard, the communication frequency of electronic tag and read write line is 840-845MHz or 920-925MHz.
With identification code in described electronic tag, be arranged on the facade of trackside fixed object, the exclusive identification code in electronic tag and electronic tag geographical location information are at background system binding also one_to_one corresponding.
Described read write line is arranged in bus, and read write line is bound by IP address, MAC Address or unique identification and place bus.
The power supply of described read write line is vehicle power supply, and read write line device can identify at a distance to electronic tag.
Described read write line supports that the multiple cellular mobile communication networks such as GPRS/3G/4G LTE are connected with background system.
Described background system receives read write line and sends the link location information of returning, and completes the location to bus, reads while write the inquiry that device can receive background system.
Instant invention overcomes traditional GPS and Beidou satellite navigation system location out of true and the shortcoming of blind area, public traffic management person can grasp the positional information of public transport in real time, locates in real time, calls out the stops, scheduling etc. for public transport, is convenient to management.
Accompanying drawing explanation
Fig. 1 is the system composition diagram of a kind of bus positioning system based on UHF RFID technique of the present invention.
Embodiment
The embodiment of a kind of bus positioning system based on UHF RFID technique of the present invention is described in detail below in conjunction with accompanying drawing.
Described a kind of bus positioning system based on UHF RFID technique comprises electronic tag, read write line and background system composition, with identification code in electronic tag, electronic tag is communicated by radio frequency signal with read write line, the information in read write line reading electronic labels; Read write line is connected with background system by wireless transmission, and read write line is sent to background system the electronic labeling information recognized, and background system determines the position of current bus by analytical electron label information.
In the present embodiment, described electronic tag and read write line air interface protocol standard are GB GBT29768-2013 " infotech radio-frequency (RF) identification 800-900MHz air interface protocol ", and the communication frequency of electronic tag and read write line is 840-845MHz.More accurate in order to locate, electronic tag is pasted onto on street lamp on roadside, traffic lights, monitoring vertical rod post, and on the wall of both sides, tunnel.Because traffic vertical rod is all metal material, therefore the electronic tag that the present embodiment is preferentially selected is anti-metal tag.
In the present embodiment, read write line is arranged on the glass for vehicle window on the right side of bus, and reading and writing device antenna direction is facing to electronic tag, so that acquisition best read-write effect.
In the present embodiment, store the geographical location information of electronic tag and the exclusive identification code of electronic tag in background system, identification code is corresponding with the geographic position of road.When the bus being loaded with read write line normally travels, when the electronic tag be pasted onto on the facade of trackside fixed object enters in the identification range of read write line, read write line identifies the identification code in electronic tag, and be sent to background system in real time by cordless communication network, background system analyzes this identification code, and then obtains the geographical location information of corresponding bus.
