摘　　要：介绍了一种实现聚乙烯管道电熔焊接的智能化仪器。以单片机PIC16F877为测控核心,采用交流调压模块DTY-H220D35E、传感技术和模糊PID控制算法实现了焊接电压的控制,并且用环境温度测量值对焊接电压进行补偿;激光条码扫描器自动录入管件参数;EEPROM存储器记录焊接数据;采用传感技术实现管件断路、供电电源超压、供电电源欠压和过流检测。此聚乙烯管道电熔焊接机具有焊接质量高、使用方便和节能等特点。This paper introduces an intelligent electro-fusion joining machine for polyethylene pines. Fusion voltage is controlled by Single Chip Microcontroller PIC16F877 via AC voltage regulation module DTY-H220D35E, sensor techniques and Fuzzy PID control algorithm, and effect of environment temperature on joining quality is eliminated by voltage compensation. The joining machine has many built-in functions, such as automatic recognition system of bar cede for electro-fusion joints, EEPROM memory for recording joining data, open circuit detection in joints, overvoltage protection, lack of voltage protection and overcurrent protection. The joining machine has features of higher joining quality, convenience and energy saving.
