Research Of Automobile Monitors System Based On Mobile Net

The vehicle the main body of a book is studied is that the vehicle monitors the systematic important component with supervisory control system.Intelligence vehicle system is a key of entire intelligence traffic large scale system ingredient. Without vehicle system's intellectualized, vehicle information can not the effect be had, be collected rapidly, the function difficult to realize one is complete right away very , timely reaction intelligence traffic is systematic. Intelligence vehicle system has been various technology synthesis such as electron technology , computer art , it has included vehicle system and technologies such as being loaded with the navigation system fixing position, being loaded with supervisory control system , sound control technique from when vehicle keeping system , dangerous periphery vehicle warning system , automation driving technology , vehicle voluntarily.The main body of a book is loaded with first to vehicle monitoring essential two system middle technologies, allocation technology and the communication technology, carry out the choice discussing that. Pass the communication network that allocation technology and China having considered , choosing GPS respectively in the field of the broad degree , cost etc. applying from realization, move. Be loaded with the terminal population design plan having brought forward vehicle here on the basis. Owe a terminal the data receiving the NMEA form allocation that the GPS receiver issues, extract required longitude out of, thinking degree waits for information; Collect the bodywork switch amounts information; The form complying with and controlling the GSM/GPRS module that these information is served two kinds with SMS/GPRS has given supervisory control centre and consumer mobile telephone , has ensured that system also can work in very bad network environment.The thesis has given vehicle having dispatched a vehicle the detailed scheme being loaded with terminal hardware design , has emphasized the module and communication module fixing position to ARM processor circumferential having been in progress discuss that, have given the selections implanting dyadic vehicle being loaded with the supervisory control terminal host controller out the type and characteristic property in proper order detailedly; Module characteristic property, interface and data fixing position export a form; Principle communicating by letter as well as module characteristic property , structure and interface communicating by letter. And give the amounts simulating amounts/ switches out the design collecting circuit and the control circuit.The software plan adopted can be described as an embedded operating system+Hardware driver+application program. The application program was developed on the basis ofμC/OS-Ⅱand divided into mufti-task, which simplified the software design of application system and improved the reliability of system.
