摘要
针对多频激电仪中接收机对发送机和控制器无法进行智能远程控制的现状,开发了一套基于GPRS的多频激电仪远程测控系统.该系统由通信模块、上位机和下位机组成.通信模块由3块插入SIM卡的DTU组成,它通过短信方式完成远程数据传输功能,实现上位机和下位机之间的数据通信.上位机作为本系统的主动站,负责发起连接,对下位机进行状态监测和功能控制.下位机作为从动站,等待上位机的连接,并执行上位机的各种控制命令,在发生紧急事件的时候能主动向上位机报警.3个模块在该系统中相互协调,共同完成系统的各项功能.试验表明,该控制系统能够正常工作,在野外工作时能降低劳动强度,提高工作效率.
A remote control and measurement system for multi-frequency IP instrument based on GPRS is developed to resolve the present situation that the receiver cannot communicate with transmitters and the transmitter controller in electrical exploration.The system is composed of the communication module,the host computer and the slave computer.The communication module contains three DTU inserted into the SIM card.It implements the function of remote data transmission via message and realizes data communication between the host computer and the slave computer.As the active station of the system,the host computer initiates connection and fulfills the condition monitoring as well as function control to the slave computer.As the passive station,the slave computer receives connection and carries out commands from the host computer.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.
