Description
Technical field
The present invention relates to a kind of vehicle-mounted GPRS system, particularly a kind of embedded vehicle-mounted GPRS system.
Background technology
At present, along with the raising of living standards of the people, the vehicles are more and more, and security service also more and more comes into one's own, and especially vehicle-mounted monitoring system receives the concern of industry more and more.
Vehicle-mounted GPRS system combines GPRS, GPS technology, utilizes the data-transformation facility of GPRS, realizes the bidirectional data transfers of moving vehicle and Surveillance center, to implement the monitoring to travel condition of vehicle, safe condition, state of the art.
To be the U.S. develop, last 20 years, expensive 20,000,000,000 dollars, built up comprehensively, have the new generation satellite navigation and the navigation system of carrying out comprehensive real-time three-dimensional navigation and stationkeeping ability in sea, land and sky in 1994 since the seventies in last century global positioning system (GPS, Global Positioning System).
GPRS is the standard of relevant grouped data defined in the european telecommunication association gsm system.It adopts channel binding (design of present GPRS can realize bundling) and strengthens data rate and improves realization access at a high speed in a carrier frequency or 8 channels, air interface transmission rate up to 115kbps can be provided in theory, make some mobile subscribers can share a wireless channel simultaneously, a mobile subscriber also can use a plurality of wireless channels.The actual user who does not send or receive packet only accounts for very little a part of Internet resources, and network capacity is only just occupied when actual the transmission.
In order to realize GPRS, need in existing GSM network, introduce 3 kinds of new logical network entities: Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN) and packet control unit (PCU).The most basic difference of GPRS and existing GSM voice system is, GSM is a kind of circuit switching system, and GPRS is a kind of packet switching system.Therefore, that GPRS is specially adapted to be interrupted, paroxysmal or frequent, a spot of transfer of data also are applicable to big data quantity transmission once in a while.These characteristics just are being fit to great majority and are moving interconnected application.
GPS-GPRS navigation system car-mounted terminal uploads to system server with the Current GPS geographical location information that it obtained by the GPRS mode.Client can be passed through special GIS software or IE browsing mode, current position, the speed of a motor vehicle and the direct of travel at monitoring vehicle place of being subjected to monitored in real time, and can control car-mounted terminal by network, realize the bidirectional data transfers of moving vehicle and Surveillance center, finish monitoring travel condition of vehicle, safe condition, state of the art.
Existing vehicle-mounted GPRS system is mainly based on GPRS equipment external control on the market, and control rate is slow, and software upgrading is slow.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, and a kind of embedded vehicle-mounted GPRS system is provided, and it controls GPRS equipment and ancillary equipment with the embedded functional module MCU of gprs system.Control rate is fast, and software upgrading is easy.
