Remote Fault Diagnosis In Machinery And Equipment In The Internet-based Research

"The technology of remote fault diagnosis about mechanical equipments based on Internet" is one new technology. It is developed following the quick development of Network; it combines traditional fault diagnosis with computer science and communication technology. The complicacies and veracities of remote fault diagnosis about mechanical equipments increased, and the old PC system of fault diagnosis could not finish the diagnostic work. So the research N developments and application of "the technology of remote fault diagnosis about mechanical equipments based on Internet" become more and more exigent and important.This paper starts with the frame and the system of "the technology of remote fault diagnosis about mechanical equipments based on Internet" , in succession, it expatiates the technologies interrelated to remote fault diagnosis. This paper is brought forward from practical application, and its research also combines with the old PC system and practical application.In the kernel part of this paper, it mostly expatiates following several problems:K How to combine the system of the software and hardware of remote fault diagnosis with the old system. That includes the problem of establishing one website, the problem of network interface and the scheme of hardware.2, The message transmission between users and diagnosis center concludes the problem of sending messages safely , the protocols of sending messages and the interaction between users and diagnosis center when transferring messages, especially on-line interaction .SN How to build all kinds of databases ---- multimedia databasesand professional databases , such as bearing parameter database, transmission system parameter database, equipment drawing database, and so on. And how to search data from these databases on-line.During my research, the real status of our graduate school ?"Institute of Vibration Engineering of DLUT" and users was thoughtover all the time. For example, the problems of website safety; theproblems of how to choosing mechanical pictures; the problems of theburst of on-line interaction; how to build temporary database whensearching data; how to deal with the relation, of "exact search" and "fuzzy search" .The technology of remote fault diagnosis will develop quickly with ths advancement of the relating technologies. And the research production must be fit for the real status of users. The uppermost object of his paper is that user can achieve.the fault diagnosis and with highest quality through "remote fault diagnosis" , but the cost is the lowest.
