Development And Research On Real-time Condition Based Monitoring System

In recent years, various equipment is developed in the way of large-scale, complication and intelligence. The level of automatization becomes much higher. But some problems appeared along with the trend. If some important equipment is in trouble in some time, the consequent result could not only threaten people's lives, but also could bring huge economy loss and huge impact to the society. Under this background, the people's requirements that research and developing condition based monitoring system become more and more urgent.The development of condition based monitoring system started in 1970s last century. In the following years, along with the appearance of much new technology, the condition based monitoring systems are developing fast and being used in many areas. Based in the research the dissertation brings up railway real-time condition based monitoring system based in railway system.This system is composed of two parts, the real-time data monitoring system and the data collecting system. The real-time data monitoring system is developed in the platform of C++ Builder. It adopts Object Oriented thinking and multi-thread technology. It has the function of display, storage and management data. The real-time data monitoring system is divided into six modules: the communication module, password management module, name management module, database management module, single mode module and multiply mode module. And the single mode and multiply mode are the two working states of the system.The real-time data monitoring system adopt the Client/Server structure. The client part is the data monitoring system itself. And the server part is the database server. The system adopts SQL Server as the database server to store data. The data monitoring system sends requests such as storing data, update data and so on to the database server. The database server executes different commands depending on the different requests and returns the result to the data monitoring system. The C/S structure can do well in storing data efficiently.The function of the data collection part is collecting and disposing data. This part receives the various instruments transformed from the real-time data monitoring system and response to these instruments. It returns data to the real-time data monitoring system through serial communication. And the Real-time data monitoring system disposes these data.This system implements the railway real-time condition based monitoring. And it offers basis for the further detecting in railway.
