| With the development of economy and the increase of power load in our country,the substation is also showing geometric growth.The maintenance and repair of the high voltage equipment,wire racks,switches,and knife gates in substation,need to do safety measures and warning slogans,to prevent people into the non-working area,so as to avoid casualties and property losses in the equipments.The traditional management method,usually through setting isolation net,the high-voltage equipment maintenance is surrounded,to prevent non-staff into the non-working area to achieve security in human supervision,which is easy to cause casualties and equipment losses.In order to solve the problem,this paper compares the advantages and disadvantages of several common perimeter protection systems,summed up the shortcomings of these protection systems,combined with the actual application requirements,puts forward a kind of intelligent alarm system which is based on infrared curtain,describes in detail the the system architecture,the system design principle and the realization method and process of installation and debugging.Through the verification of the actual site,fully proved that the intelligent alarm system can greatly improve the management efficiency and reduce the occurrence of safety accidents,ensure the safety production of substation.The research of the Intelligent alarm system based on infrared curtain in this paper,by means of the photoelectric sensor can carry on the early warning of the illegal intrusion,through the linkage video monitoring equipment of substation to monitor and record personnel who is entering into the illegal work-area with video monitoring linkage,and then the back-end users can communicate with the front-end users by the way of the video-voice intercom system,the system also has the authentication function of mifare 1 card,the staff come in and out of the defence area according to authority card and the system record the inspection personnel inspection line.When someone illegally entered the non-working area,the system will remind the personnel on the spot through the sound and light alarm,compared to other perimeter protection system,the system has the early warning and video linkage,credit card authentication,live voice prompts and other advantages,and has a low false alarm rate and false negative rate,the security is very suitable for the application in the power industry. |
