【Abstract】 Based on MSP430 single chip microcomputer,a portable infrared thermometer used for electric power equipments is designed. The thermometer locates measurement location using radio frequency identification( RFID) technology. And based on noncontact and distant measurement characteristics,the design uses infrared temperature measuring sensor MLX90614 to measure the target temperature; using environment temperature sensor to collect environment temperature,the equipment corrects the target temperature according to the principle of infrared temperature measurement. The system built-in SD2200 time module to record measuring time accurately. Built-in USB read-write module to record the location,target temperature,environment temperature,modification temperature and measuring time in the internal SD card for importing computers conveniently and generating report. The portable thermometer puts an end to the missing and wrong record during power checking,and generates reports to make reading convenient,and greatly improves work efficiency.更多还原
