Research Of Intelligence Signal Equipment Of Railway Emergency System

With the fast development of railway in our country, especially the special railway line will be introduced, signal equipment of railway would be used, at the same time, there is a contradiction between management of railway equipment and the maintain ability of workers, so it is very important to solve the contradiction for the security of the whole railway. Nowadays, signal microcomputer supervision systems are researched widely all over the world, and they are applied on the equipment of railway specially signal equipment. However these systems can only monitor the status of those signal equipment, and can't provide methods that can deal with the accidents of those signal equipment.So this paper will design a kind of new system, which is called expert system of accident diagnosis, can automatically provide maintaining dynamically according to accident of signal equipment. How to design the system, after making a study of fact, it is feasible that knowledge-based of expert system can be built well with the help of XML technology, and mechanism reasoning of expert system is based on the logical tree of fault diagnosing, and expert system can exchange information by the use of web services, so that it can get more information to deal with local fault, and then datum can be dynamically analyzed through the use of the reasoning, and the paper will promote a ideal based on the rule frame of analyzing datum. As so the system will be current, and be maintained well. And the system is used in the signal department of Xuzhou.
