摘要
介绍了基于PIC单片机的过载继电器。分析了该系统的工作原理,描述了其硬件配置和软件设计方法。该继电器不仅更准确更有效地保护电动机,而且能充分发挥电动机的过载能力。同时,还能实现与上位机的通信,达到了电动机保护智能化的要求。
An overload relay which based on PIC single-chip microcomputer was introduced. The work principle, hardware structure and software designing were presented. This relay not only can protect the electromotor more exactly and effectively, but also can exert it＇s capability of overload well, and realize aerial communication between the overload relay and superior computer, too. Then it reaches the request of its intelligent protection.
