摘要
物流公司需要实时监控货车的运行状态,就必须在货车上安装车载监控终端。传统的监控方式采用GSM技术,通过短信息业务传送数据。由于数据传输速度慢、费用高等问题,GPRS技术应运而生。该技术在车载监控终端与监控中心通信服务器之间建立了一条费用低、稳定性好、实时性高、通信覆盖范围广的双向无线数据传输通道,满足了设计需求。
In order to let logistics company knows the real time monitoring operation state of trucks, it is necessary to set a vehicle monitoring terminal. The traditional monitoring uses the way GSM technology, through short message service transmitting data. Due to the slow speed of data transmission and higher costs, GPRS technology arises at the historic moment. It sets up a bidirectional wireless data transmision channel featured lowcost, good stability high realtime and broadcoverage between the teminal and the monitoring center, to satisfy the design requirements.
