摘　　要：设计了用于橡胶生产的温度控制系统,在温度采集、处理模块中采用基于算术平均与中值滤波相结合的防脉冲干扰平均滤波法对温度数据进行处理,输出控制部分采用积分分离PID控制算法。经测试,该系统稳定性高、温度调整时间短,温度信号的测量控制精度能达到0.5℃。We designed a temperature measurement and control system for rubber production. We employed pulse interference suppression average filtering approach based on average filtering and median filtering to process temperature data in a temperature data collection and processing module. We used an integral separation PID algorithm in its output. Experiment shows that the system has high stability, short temperature adjustment time, and a control accuracy of 0. 5℃ for a temperature signal.
