对抽油机位置及状态智能监测系统进行了总体设计，以AVR单片机作为控制核心，利用GPS对油田抽油机进行精确定位，通过水银开关对抽油机的工作状态进行监测。通过SIM900A芯片将油井位置、抽油机的工作状态、控制板的温度、时间、信号强度以及SIM卡余额等信息通过GPRS通信传至控制中心，实现了对抽油机位置及状态的智能监测。%The intelligent position and state monitoring system for oil pumping unit was designed , in which , having AVR single chip microcomputer taken as the control core and GPS employed to locate oil pumping unit ’ s position accurately and to monitor its working state through the mercury switch; and with the help of SIM900 A chip and the GPRS communication , the information like oil pumping unit ’ s position and working state, the control board ’ s temperature , time and signal intensity , as well as the SIM card ’ s balances can be transmitted to the control center so that auto-location and state monitoring of the oil pumping unit can be real-ized.
