接地电阻监测仪设计

Design of grounding resistance monitor instrument

论述了使用比较法的接地电阻监测方法和微功耗接地电阻监测仪电路、程序设计.该仪器选用MSP430F1121芯片作为核心元件,使电路简化并达到了微功耗效果.

The comparative method of grounding resistance monitor is discussed, and the design of the circuit and program of grounding resistance monitor device with ultra-low power consumption is presented. Taking MSP 430F1211 as the core component, the circuit is simple and ultra-low power consumptive.
