摘要
针对爆炸场温度测试的特点设计了一种基于CPLD和单片机控制、SRAM存储的新型温度采集系统。该系统采用NANMAC的E12型热电偶作为温度测量端,DS600温度传感器对冷端进行温度补偿,具有同步高速采集,触发及工作参数可调的特性。系统采用单片机与USB相结合的通信接口,操作简便可靠。
According to the characteristics of explosion field temperature testing, a new temperature collection system based on complex programmable logic device （ CPLD）, single chip microcontroller （SCM） and static ram （SRAM） is proposed. The system adopts the NANMAC E12 type of thermocouple as the temperature sensor, DS600 temperature sensor for cold temperature compensation, with rapid synchronous collection, trigger and working parameters adjustable characteristics. The system used SCM combined with USB communication interface, easy operation and reliable.
