摘　　要：研制了一种多通道冻土温度含水率监测装置,用于冻土层区域土壤温度和含水率的监测。监测仪选用特制的电容式双参数传感器感知土层温度和含水率,以PIC32MX150F128单片机(MCU)作为核心,完成采集、存储和传输时序的控制,可同时采集8个通道数据。目前,监测仪已应用于张家口市崇礼县枯杨树村冻土层的监测。实际应用表明:研制的监测仪工作稳定可靠,能够监测冻土层的温度和含水率2种参数,为地质环境调查提供技术支撑。A multi-channel monitoring device for temperature and moisture content of frozen soil is researched and fabricated. The monitor uses the special capacitive type double-parameter sensor to sense soil temperature and moisture content,uses PIC32 MX150 F128 microcontroller unit（ MCU） as the core,completes the acquisition,storage and transmission timing control,can simultaneously acquire data of 8 channels. At present,the monitoring instrument is applied in Chongli County of Zhangjiakou City,withered poplar frozen soil layer. The practical application shows that the monitoring instrument is stable and reliable,can monitor two kinds of parameters of temperature and moisture content of frozen soil,and provides technical support for geological environment investigation.
