Study On The Condition Monitoring Of Cable Ditch Water Level And The Application Of Distributed Intelligent Drainage System Based On Wireless Measurement And Control

At present,with the advancement of urbanization,the development of power market is fast,the development of cable is becoming more and more important.Most of the cable communication channel in the city is built under the road,the terrain is obviously low,in the rainy day or southern typhoon and other harsh environment,rainwater dirty water will flow from high to the well,even if the cable groove bracket built in the Highlands,will also be corroded by rain and so on.Cable long-term soaking or soaking in the water,will be corroded by the water or even cause the cable to burst,the consequences are unthinkable.How to solve the problem of water accumulation and temperature and humidity in cable ditch and ensure the safe operation of cable is the difficulty that needs to be solved technically.In order to solve the above problems,the main function of the system is to collect the water level signal,monitor the water level condition and control the drainage.Therefore,based on wireless measurement and control technology,the system uses pressure sensor to monitor water level and AT89S52 single chip microcomputer as central processor to realize the functions of water level measurement and water level control.In this disseration,based on wireless measurement and control,the cable channel water level monitoring and distributed intelligent drainage system are proposed to realize on-line monitoring of water level and intelligent drainage.Firstly,the application of self-monitoring and drainage technology at home and abroad is compared,and then the design requirements and plans to be used are demonstrated.At the same time,the disseration designs the main control module,pressure sensing module,wireless transmission module and distributed system in the water level monitoring system.Finally,the flow and software of water level monitoring and distributed intelligent drainage system are refined and applied.In this disseration,the on-line monitoring of the water level of substation cable ditch and the intelligent drainage system developed can effectively improve the level of equipment inspection automation in the power network operation department,strengthen the safety control of power network equipment,and have good social and economic benefits.At the same time,it has a wide range of engineering application prospects.
