Design And Implementation Of Electric Anti Maloperation Computer Keys

With the rapid development of the national economy and the continuous improvement of living standards, people on the power supply reliability and power quality put forward higher requirements. So to develop computer safer, more complete, more reliable model of anti misoperation locking device.The main research work of this paper is: analysis of the system requirements, determine the soft, hardware structure. Production of anti misoperation locking keys on the computer, computer key of anti maloperation system is the bridge between hardware operation and operation, it is to use the original RTU acquisition station real telesignal data, using computer key upload virtual remote signal, the station operation object state information acquisition. Through computer simulation, preview, modified produce correct operation ticket information, computer key input. Operation, computer keys according to these information, in turn to each of the specific code lock, so as to realize the misoperation lockout station full range, improve the level of automation of substation, and operation safety, reliability and economy.This paper presents a method of anti misoperation locking device, the new design. Implementation of a hardware module, storage module, identification ID module, HDMI module, liquid crystal module cohesion between, and with the host computer communication. Finally, C source code very good realization of the function of each component, and the entire system will achieve good operability.
