电力设备温度无线监测系统中的关键电路设计

摘要

鉴于电力设备发热点温度测量的重要性,基于无线传感技术,从经济性、实用性等角度出发设计了一种新颖的、低功耗的、基于时钟芯片和晶体管的定时控制电路,以及一种低成本的、抗电磁干扰性强的、基于I/O口和RC充放电的温度采集电路.基于这两个电路实现的温度无线监测系统可用于对成本和功耗有较高要求的无线温度监测领域.%In view of the importance of electrical equipment hot spot temperature measurement,and using wireless sensor technology,we put forward a novel,low-power timing control circuit based on clock chips and transistors from the perspective of economy and practicality,also introduce a low-cost,strong electromagnetic interference resistance based on the I/O port and the RC charging and discharging,temperature acquisition circuit.The system can be used for a wireless temperature monitoring field which has high requirements of cost and power consumption.
