一种便携式可通信编程器的设计与应用

Design and Application of a Portable Communicating Programmer

介绍了以微程序控制器(MCU)为核心的一种便携式可通信编程器的基本工作原理及功能,给出了编程器硬件接口电路设计方法及软件流程。基于MODBUS-RTU通信协议设计的手持编程器能用来实现智能型断路器的现场参数设置、参数查询、分合测试等功能,并具有通信状态指示功能,给现场工作带来极大便利。

Introduction was made to the basic working principle and function of portable communicating programmer taking microprogrammed control unit （MCU） as the core, the programmer hardware interface circuit design method and software flow given. Based on MODBUS-RTU communication protocol, a designed portable programmer can be used to realize intelligent circuit-breakers＇ site parameters setting, parameters inquiry, making and breaking test etc functions and with communication states indication function, bringing site work great convenience.
