Effective architecture for Web-based maintenance system and its security

Keeping machine running without failure is vital to maintain manufacturing productivity. Any loss in production and service due to equipment malfunction is unacceptable. The use of Web-based maintenance helps to detect defective machine in its early stage and thus avoid costly failure. It provides an easy way for the operator to evaluate the performance of the distant located machines. The architecture of our proposed Web-based maintenance has been redesigned to reduce the burden of the main server. The heavy loading situation which often occurs in the main server can be avoided. Beside architecture, several crypto mechanisms have been added to the system. With the aids of those crypto mechanisms, the security of the Web-based maintenance has been significantly enhanced. The data can be transferred safety and the accuracy of the results can be verified. Our Web-based maintenance is well equipped with Web-enabled and advanced fault diagnostic tools. It works more effectively and securely as compared to conventional Web-based maintenance.
