Can run the operation or management of the client on-line monitoring belt transport traffic, while the user has permission to draw the historical data query to the server, and failure analysis. 2.1 Data Acquisition belt scale commonly used communication port RS. 485 standard, which is used in computer network TCP / IP standard is inconsistent. To this end,<a href="http://www.mbt-sandalen.org" target="_blank" class="postlink">MBT schuhe Günstig</a>, in terms of hardware converter with RS-485--TCP/IP belt scale computer network communication port and power connection. Thus, installed on the server only connected to the data acquisition program Chang Wang, you can read the electronic belt transmission belt traffic in real time, integrating flow data. 22 Power System Engineering Volume 21, 2005 Figure 2 Network topology control 2.2 Monitoring on-line monitoring module list showing the belt scale real-time data to any of these two curves show real-time traffic flow changes in the belt, shown in Figure 3 . At the same time, online monitoring module for real-time data anomaly to the text color, sound, data query reports 2.3 management history can be brought to check the belt to the server running records, observe the traffic distribution, and focus on the operation of the failure analysis data. 2.4 Failure Analysis application to the belt number, serial number belt, query duration of the overload limit of parameters of the stored procedure call to the belt scale historical data, the abnormal flow of node data, shown in Figure 4. Overloading failure analysis section of the module will eventually happen duration of the overload type, frequency and other information available to management staff in tabular form. On this basis, according to the list of Remembrance abnormal overload condition section of the belt transport flow distribution. 2.5 parameter set parameters module provides management functions belt scale, may at any time of belt transport traffic parameters (alarm value, alarm value) and the belt scale is set into operation, making diagnosis more flexible. A recent list of abnormal data in order to alert the operator attention. = J History Wai 3 Conclusion Shen Qu Dadeng t = J; at p 【.

This kind of fault-based analysis of the historical database management the flexibility of combining the thinking of the belt Transport diagnosis, search for abnormal state flux distribution, on the conveyer belt to make an objective evaluation of operating conditions for carrying out maintenance work provided the basis. (2) database for data analysis method is not limited to coal monitoring system failure analysis, this method can be extended to the historical database, data mining, analysis of system stability and so on. (3) in the failure analysis of electronic belt developed on the basis of online monitoring and fault analysis software takes full advantage of the power plant existing equipment to achieve flow of power-line monitoring of coal conveyer belt to solve the coal measures show the limitations of single-point dial to improve the safety of the unit I run the health and economy.
