Remote Measurement and Control System Based on GPRS for Multi-frequency IP Instrument

摘要

We have developed a remote measurement and control system based on GPRS for Multi-frequency IP Instrument to resolve the problem that the receiver cannot control the transmitter and controller remotely in electrical exploration. The system is composed of communication module,host apparatus and slave apparatus. Communication module contains three DTUs inserted with three SIM cards,respectively,which implements the function of remote data transmission via message way and realizes data communication between host apparatus and slave apparatus. As the active station of system,the host apparatus initiates connection and fulfills the monitoring as well as function control of slave apparatus. As the passive station,the slave apparatus receives connection and carries out any command from host apparatus. Three modules realize mutual coordination and various functions. Our test of the system shows that it ensures normal operation and reduces labor intensity as well as highly improves work efficiency for electrical exploration which is carried out in outdoor area.
