系统以 S3C2440处理器作为控制核心,主要包括摄像头、GPS 导航模块、GPRS 模块、LCD 液晶显示模块以及手持终端等.手持终端通过 GPRS 模块向主机发送请求短信,主机调用 GPS 模块获得定位数据,通过短信传送至终端,终端接收短信,并将校车接送学生上下车过程中的各种信息显示在短信上.本系统最大的特色是远程监控,终端可以通过特定短信来请求主机拍摄校车内学生的照片并传回终端显示.本系统巧妙使用了数个缓冲区来存储用户短信、AT 返回结果以及定位短信等数据,高效实现了各种消息的获得和处理.远程拍照功能集合了短信收发、TCP 数据收发以及摄像头操作等多项技术.

The system use S3C2440 processor as control core, mainly including cameras, GPS navigation module and GPRS module, LCD liquid crystal display modules and hand-held ter-minals, etc. Hand terminal through the GPRS module to host send request message, the host call GPS module for positioning data, through the message is sent to a terminal, terminal receiving message, and students in the process of buses get all kinds of in-formation displayed in the message This system the biggest fea-ture of remote photos, terminal can through the specific text mes-sages to request host school shooting in students' photos and back to the terminal display. This system clever use in a number of buffer to store user message, AT returns the results as well as the orientation message data, etc. high efficiency and realize the vari-ous news acquisition and processing. Remote photos function set the SMS transceiver, TCP data transceiver and camera operation technology, etc.
