The Application Of The Building Electrical Fault Diagnosis Technology

Today, with the rapid development of science and technology, Intelligent buildings havesprung up, and at the same time with the increasing of the subsystem,such as，lighting systems,fire systems, security systems, underground parking, wireless network, early detection of firesmoking, etc.，so the occurrence of failure is inevitable. Based on this, the theory of faultdiagnosis algorithm is applied to modern architecture, when fault occurs can quickly pinpoint,so as to shorten the mean time to repair, so that it can increase the reliability of the wholesystem. Before this, Relatively few people to research of building electrical fault, more isdedicated to the research to protect the supply network; In addition, conventional wisdomsuggests building electric voltage grade involved is low, the harmfulness of breakdown is low,the troubleshooting method is simple, a lot of people ignored. Therefore, Building electricalfault self-diagnosis technology proposed has the leading meaning.The purpose of this study isunder laboratory conditions, to verify the effectiveness of the fault diagnosis technology, andapplied to practical engineering, eventually to improve the reliability of building electricalsystems, the stability, ensure the safety of the owner of the electricity.This paper introduce the research results mainly from the following several aspectsFirstly, rebuilding the new building electrical experiment platform. The main job is toanalyze the schematic diagram, wiring diagram of the German import original experimental,to redesign the test bench of weak current systems, high voltage and fault setting circuitsystem, and then install and debug the new test bench, at last, collect and analyze the faultdata.Secondly, designing the building electrical lighting subsystem experiment platform. Themain job is to choose the variety of lamps and lanterns, design and installate the lightingsystem, finally to collect the relevant data such as illumination, brightness values in differentconditions.Thirdly, building the electrical experimental platform for data acquisition system. Themain job is to design the data acquisition system and purchase the current, voltage sensors forlaying a foundation of the feasibility to implement in the future.Fourthly, Theoretical research of fault diagnosis algorithm. The main job is to analyzeelectrical diagnosis algorithm structure in this building of experiment platform based onmultiple Agent，puts forward the building electrical fault diagnosis system diagram,taskdecomposition diagram,fault task decomposition of the test bench, multiple Agentmanagement structure, Agent algorithm research, etc., Finally to realize fault diagnosisalgorithm is proposed with the help of Anylogic software. The algorithm above theory isverified by experiment.
