Abstract

The utility model relates a global positioning system (GPS) terminal, belonging to the field of the intelligent transportation system and aiming at solving the problems that the GPS terminal generally adopted at present positions and navigates mainly by a global positioning satellite (GPS) and has signal function, and in the whole position and navigation process, the vehicle only obtains position data but can not communicate with an administration center. The GPS terminal uses a wireless communication network such as a general packet radio service (GPRS) or a code division multiple access (CDMA) as communication medium, uses a GPS positioning technology, a computer technology thereof and the other measures and comprehensively uses a vectorization geographic information electronic map software platform to realize the precise position, the dynamic navigation, the alarming to seek help, the information service, the Chinese short message receiving and transmitting, the talk by voice, the working state monitoring and other functions of the vehicle and really realize the communication between the vehicle and the administration center on the basis of the traditional GPS navigation function. The utility model has small volume, large practical value, low cost and wide application range and can be popularized.

Description

The GPS terminal

Technical field

The utility model relates to the intelligent transportation system field, is specifically related to a kind of GPS terminal.

Background technology

The present GPS terminal that generally adopts, working method mainly are to position and navigate by gps satellite, and function is comparatively single.And in the whole process, vehicle only is to obtain locator data, can't carry out communication with administrative center.

The utility model content

The purpose of this utility model is to provide a kind of system scheme based on GPS navigation and cordless communication network.

The utility model utilizes cordless communication network (GPRS/CDMA) as telecommunication media, utilize means such as GPS location technology and computer technology thereof, in conjunction with utilization vector quantization geography information electronic chart software platform, realize to accurate location, dynamic navigation, the warning of vehicle seek help, functions such as information service, Chinese sending and receiving short messages, voice call and the supervision of vehicle operation state.

The utility model is made up of housing, main circuit board and main panel.Main panel is provided with Peripheral Interface, status indicator lamp, SIM card slot and antennal interface (comprising radio antenna and gps antenna); Main circuit board is made up of wireless communication module, GPS locating module and governor circuit.

Wireless communication module, GPS locating module and governor circuit comprise wireless communication protocol, GPS communication protocol, expansion interface, RS232 serial communication protocol, keyboard, voice output, display driver.Wireless communication protocol is corresponding to cordless communication network (GPRS/CDMA), GPS communication protocol is corresponding to the GPS positioning system, expansion interface is corresponding to external expansion equipment (hand-held screen, MIC head, camera or the like), RS232 communication protocol is used for communicating by letter between each module and external equipment and master cpu, keyboard is corresponding to the button operation of hand-held screen, voice output is corresponding to the loudspeaker of hand-held screen, and display driver is corresponding to 192 * 64 hand-held display screens.

When the utility model uses, be fixed in the car, connect antenna and vehicle power, can use.

The most outstanding advantage of the present utility model is the use that mutually combines of GPS positioning system and cordless communication network, not only can navigate, more can in time communicate by letter, not only promote the convenience of trip, more can realize the real-time management of administrative center vehicle with administrative center.Note simultaneously having controlled volume, cost, easy to install, use in extensive rangely, be beneficial to popularization.
