摘　　要：介绍了基于GPRS的路用试验仪器远程监测系统的组网方案,分析了公路工地实验室的特点,制定了重发机制、心跳机制、校验机制和本地端将数据进行编号并备份存储,远程端索要数据等保障系统可靠通信的通信协议,并详细介绍了通信的软件实现。工程应用和通信可靠性试验证明设计的远程测量系统具有较高的通信可靠性和运行稳定性。A networking solution of remote monitoring system based on GPRS for road-testing equipments is in- troduced. According to the characteristics of highway site laboratory, an application-layer communication proto- col is proposed, including retransmission mechanism, heartbeat mechanism, checking mechanism, the data num- bered and backup stored mechanism of the remote monitoring system in local terminal while remote end can ask for data transmission. Communication software is introduced in detail. Engineering application and commu- nication reliability experiments prove that the proposed remote monitoring system has higher communication re- liability and operation stability.
