摘要
提出了一套基于工业标准体系结构(ISA)总线和RS-485网络的高温超导磁储能(SMES)监控系统。介绍了系统的通信协议,描述了系统的总体结构及主要功能。为提高系统的实时响应性能和数字信号处理能力,在硬件上采用了数字信号处理器(DSP)技术;采用模块化的程序设计方法,同时通过利用DSP的中断资源,解决了多任务对CPU的同时请求以及交叉的问题。实验表明,该监控装置能对整个SMES系统进行有效的状态监测与控制。
A high temperature SMES（Superconducting Magnetic Energy Storage ） monitoring and control system based on the ISA（Industry Standard Architecture） bus and the RS-485 network is presented. The system communication protocol is introduced,and the system structure and functions are described. The DSP（Digital Signal Processor） is adopted in the hardware design to enhance the performance of real-time response and digital signal processing. Modularized programs are developed in the software design. Interruption resources of DSP are fully utilized to implement simultaneous requests of multiple tasks for the central processing unit. Experiments show that the system can effectively monitor and control the SMES system.
