Design and Implementation of the Power Watch Circuit of Groundwater Monitoring System

Abstract:

According to the characteristics of groundwater monitoring system,such as the field work unattended, replace the battery problem,the sampling time is short and standby time is long,the method is used to extend the power of life that using the watchcircuit control system under different power state automatic switching.Considering the characteristics of the system that parameter configuration commands are complex,field sampling is diverse and the communication time is not stable,thepaper puts forward the measuresthatmulti trigger source of hardware and status word of software collaborative work together to realize the system logic control.The overall power consumption of groundwater monitoring system which introduceswatch circuit is greatly reduced. Experimental results verify the feasibility of the watch circuit and show that the watch mode will become the development direction of field monitoring industry.
