摘要
提出了一种内部基于CAN总线的网络化微机保护硬件平台的设计方案。在微机保护装置内部,将各功能模块设计为智能模块,具有独立的CPU,各模块之间通过内部CAN网进行通讯。模块的网络化设计大大缩短了硬件开发周期,使基于此平台设计的微机保护装置具有一定的通用性。同时,硬件平台的网络化提高了软件的可移植性,由于各模块没有直接的电气联系,网络化的硬件平台使系统的可靠性和抗干扰能力大大提高。为实现微机保护装置的平台化提供了一个很好的解决方案,在其基础上开发的高压微机线路保护装置证明了该平台设计方案的可行性和优越性。
The design scheme of the networked hardware platform of microprocessor protection based on CAN bus was brought forward in this paper. Inside of the microprocessor relay, all functional modules were designed as intelligent modules, which have independent CPU, the modules can be communicated with each other through internal CAN bus. The networked design can be shortened hardware developing period greatly, so that the microprocessor relay has certain universality based on that platform design. Meanwhile, the networked hardware platform can improve grafting in software; due to there was no direct electrical connection between the modules, the reliability and the anti-interference ability of the system had been enhanced enormously. It provides good solution for microprocessor device platform. Based on high voltage microprocessor line protection development, it proves feasibility and advantage of that platform design scheme.
