DIAGNOSIS CONTROL METHOD IN A LOCAL CONTROL SYSTEM USING THE INTERNET

摘要

PURPOSE: A diagnosis control method in a local control system using the Internet is provided to generate and send the optimized diagnosis program to the remote MMI system. CONSTITUTION: The local control system(10) is connected to the remote DBs(201), an MMI system(202), an Internet server(20n) and other local control systems(301 - 30n) using the Internet. The local control system consists of the Internet interface part, a control module, an analog I/O part, a universal communication module, a data processing and control part and a data storage part. The data processing and control part can consist of a system control part, an algorithm part, a data processing part and an application operating part. The data processing and control part collects the newest information and data from the DBs or the servers and compares the status of the constituent parts with the stored data. If the compared difference is bigger than the allowed error range, the data processing part marks it abnormal and sends the information to the MMI system. The processing unit makes the data able to be shared using the Internet.
