摘要
对于实时性要求不高的远程被控对象,目前可以应用基于PSTN(公共交换电话网)和基于GSM(移动通信网)的低成本远程监控系统来设计,对这二种方法进行了比较。详细介绍了基于GSM的低成本远程监控系统组成以及实现方法,已经成功应用在排水泵站远程监控中。
The paper introduces the principle of the remote monitoring system with low price based on PTSN (public switched telephone network) and GSM (global system mobile). The system is suitable for the object with less real time requirement. The two methods are compared, and then the composition of the remote monitoring system based on GSM and the implement method are described to detail. The system has been applied to the remote monitoring system of the drainage pump house.
