摘　　要：采用模块化的设计,以一个支持实时仿真和跟踪,16/32位的ARM7TDMI-STMCPU微控制器LPC2132为核心,配合其他功能芯片,完成硬件设计要求。考虑到强弱电信号之间的相互电磁干扰,在整体结构上采用3层电路板,实现了强弱电信号的隔离,提高了系统的抗干扰性、运行的稳定性和人员现场操作的安全性。本控制单元设计完全符合备自投配电终端智能化、小型化、多功能化的要求。Base on the theory of modular design, this paper presents an design of terminal unit with micro controller LPC2132 of the 16/32 bit ARM7TDMI-STM CPU as the system core, which is capable of real-time simulation and tracing. In view of the presence of electromagnetic interference, a three-ply circuit board is used to isolate these different signals form different boards, guaranteeing the anti-interference, stability and security of the system. This hardware design meets the requirement of intelligentialization, miniaturization, and multi- function.
