基于唤醒模式的GPRS仪表数据采集系统低成本通讯控制策略

Low cost control strategy for instrument data acquisition system based on GPRS with wake-up-mode

针对基于永远在线方式的GPRS的流量计仪表数据采集系统维持网络通讯质量数据包频繁、通讯费用高的情况,提出降低系统运行的通讯成本,提高系统运作效率的语音唤醒,多表数据打包的改进方案。经过对比试验和现场应用,证明了该方案的经济性和可靠性。

This paper aims to solve the high communication fee of the instrument data acquisition system based on GPRS with always- on- line mode. The improved scheme reduces the communication fee and enhances efficiency by the method based on wake - up mode and multi - meters data packed. Experiment and the practical application proves the feasibility and the correctness of the improved system.
