The Research Of Graphics Processing And Remote Testing For The Logic Tester Of Metro Electrical Cabinet

Electrical cabinet is the core of the control systems of the subway.If the logical relationship of the electrical cabinet is correct is important for the control of electrical system and to keep the subway safe operation.It is needed to test the logical relationship of the electrical cabinet before it is installed in the subway.The reason to do this is to reduce the possibility of reworking after the electrical cabinet is been installed in the subway. In the past mainly rely on manual methods to test the logical configuration of electrical cabinet.But,this way will take a long time and it is easy to be undetected or error dection.especially for the complex timing.These will give the production and commissioning of trouble.can also cause economic losses.It will hidden trouble for the subway.So it is necessary to design a kind of instrument to test the logical relationship of electrical cabinet.This topic is based on the design of instrument to test the logical relation of electrical for the CSR Corporation Limited.This article introduce a kind instrumrnt for logical relation testing.The instrument includes industrial control computer, acquisition and driving system to be the basis of hardwave.The instrument can also import the logical relation of the electrical cabinet, generate the testing program.It can test the electrical cabinet an its module by using the testing software.This treatise based on the programming of MFC, and analyze the achievement of graphical display.At the same time,the treatise analyzes the problems and solution to achieve the graphical display. The treatise also analyzes how to relize the logic tester communicate with the monitoring center by using the Winsock.
