| 摘 要： | 利用数字信号处理器控制外围接口电路，对多路热敏电阻测试电路执行依次通/断电操作，循环执行，以测试其老化性能，循环次数由用户设定。在每次测试第一次通电过程中，控制动作时间比较电路启动，同时数字信号处理芯片自动记录每一路的热敏电阻的动作时间数据，并进行处理。该系统可以同时测试30只热敏元件。

| Abstract: | Using digital signal processor control peripheral equipment first,and then drive every positive temperature coefficient resistance testing circuit switch on and switch off in succession,After all the circuits finished a on/off action,the system circulated these operations untill the cycle times reach the initialization.In the first course of testing,the operating time of compare circuit is brought into play,synchronously,digital signal processor clock all the testing circuits' operating time and keep these data in corresponding locations.This system can tes 30 pieces of positive temperature coefficient resistance at a time. |
