INTEL公司生产的MCS—48系例单片机,在一个单片上集中了CPU、I/O、RAM、ROM和定时/计数器的功能。具有性能强、价格低,适用性大的优点,广泛应用于工业控制,智能仪器和计算机的智能终端中。这里我们介绍把MCS—48系例单片机应用于电力系统控制中的情况,在电力系统实时控制中,最重要的问题一是可靠性问题、二是抗干扰问题。单片机由于把一个微机系统集中在一个集成电路芯片上,就减少了整个系 The MCS-48 family of microcontrollers produced by INTEL Corp. focuses on the CPU, I / O, RAM, ROM, and timer / counter functions on a single chip. Has the advantages of strong performance, low price, applicability, widely used in industrial control, smart devices and intelligent terminals in computers. Here we introduce the application of MCS-48 Series SCM in power system control. In the real-time control of power system, one of the most important problems is the reliability problem. The other is the anti-interference problem. Microcontroller as a microcomputer system focused on an integrated circuit chip, it reduces the entire department
