Design Of Monitoring Management System For Operation Conditions Of Boiler

As the economic development of China, the contradiction between resources andenvironment is more and more serious. This thesis considers a monitoring system of19hot-water boilers, which not only located in different regions and had the various workingenvironment, but also produced by different manufacturers that resulted in various types ofthem. The developed system will establish an approach to monitor those hot-water boilerssuch that their state can be managed by remote style, and achieves the real-time monitor forthe key analog and digital variables. The main contents are as follows.1. The framework is established for the monitoring and management of hot-water boiler.By taken the temperature, flux and pressure of water inlet and outlet boiler as monitoringparameters, the man machine interface is designed by kingview and the data is gathered andprocessing by Siemens S7-200PLC.The slave computer is developed by STEP7-MicroWIN.2. The sub-system such as communication, data storage and inquiries are designed. Thecommunication between slave computer and OPC Server is achieved by MPI protocols. Andthe collected data is uploaded to the OPC Server in real-time. The master computer read thedata from OPC server, displays the variation of the monitored parameters, and alarms theabnormal condition. As a result, the communication is established between kingview and PLC.In addition, the proposed system applies the SQL Server database to store, inquire and savethe data since the defaulted database-Microsoft Access-only has2G storage, which providesthe possibility of improvement and extension.3. Aiming at many of boiler states be monitored over the same period of remote monitoring,describes Kingview network publishing and remote monitoring system.
