Design and development of communication front end processor in electric power supervisory control system

CHEN Hua-xing,LIAO Li-qing,LIU Jian-liang(School of Information Science and Engineering,Central South University,Changsha 410083,China)  
To solve the problem of communication abnormality and even interruption in a substation equipped with many measuring and protecting units,it is suggested that the communication front end processor be added between the measuring and protecting unit and the background monitor.The hardware and software design of a communication front end processor based on advanced MCF5282 embedded micro control unit(MCU) is described.Countermeasures against communication collision and jamming are put forward as well.
