智能型宽电压接触器通信接口设计

Communication Interface Design of Intelligent Wide-range Input Voltage Contactor

结合微处理器、通信和电力电子等技术,提出了对具有宽电压输入和自我调节等功能的接触器进行通信接口设计的方案,即利用单片机对接触器进行监控和与计算机互相通信,使上位机能对接触器的运行进行远程实时监控,而接触器的信息能够上传至上位机,使接触器具有通信功能。

The method which combined the technology of microcontrollers,communication and power electron-ics to let the contactor which had the functions of wide-range input voltage and auto-adaptive control had the design of communication interface was proposed.Namely,by using microcontroller to monitor and control the contactor and communicate with PC,the computer could monitor and control the contactor remotely in time,the information of the contactor also could be sent to the computer and thereby the contactor would have the function of communication.
