Design Of The Automatic Detection Device For Optical Fiber Link In The Intelligent Substation

Fiber optic link communication with long bandwidth,high capacity,strong anti-jamming ability,low transmission loss,is gradually replacing traditional communication technology,and get more extensive application.The power optical fiber communication network has become the backbone of China's power grid communication network with the construction of smart grid and the development of optical fiber communication technology.Especially in the intelligent substation,optical fiber communication is the main means of communication to achieve intelligent substation.However,there are many kinds of materials to make fiber,and there are a lot of fiber links in power optical fiber communication networks.The wide application of optical fiber communication technology to improve the quality of communication,but also lead to fiber-optic link detection more and more difficult.In this paper,according to the actual situation of fiber optic link detection in substation,a kind of optical fiber link automatic checking device is designed according to the shortcomings of traditional optical fiber link detection method.The design and analysis of the main hardware subsystems of the optical signal generator,optical signal receiver,CPU core control module and displ ay module in the automatic checking device are completed,and the hardware system is finished.The article is written by Keil using C language to design the program,and the software program of the corresponding function module is completed.The design of the automatic verification device was tested.Test results show that: detection time from the original 30 minutes down to 8.6 minutes,the correct rate of 100%.Detection efficiency has been significantly improved.
