Research And Application Of Remote Monitoring And Control Of Heating System Based On ASP.NET

With the coordinated development of Beijing,Tianjin and Hebei,Beijing and Zhang jointly host the Winter Olympics,intelligent heating has been further promoted.For heating places far away from centralized heat exchange stations and thermal power companies,in order to improve the intelligent degree of the monitoring system of the heating system,a remote monitoring system that meets managers ’ unlimited geographical time is needed to remotely monitor and issue commands to the heating system,and the intelligent control algorithm is embedded in the monitoring system to set the user-defined parameters of the heating system.But from the current remote monitoring system there are the following problems : data real-time synchronization delay;the intelligent degree of monitoring system is not high;the remote monitoring system has limitations.Therefore,the potential of remote intelligent monitoring system is great,which puts forward new and higher requirements for the application of remote monitoring system in heating system.In order to solve the above problems,this thesis studies the intelligent heating remote monitoring system based on ASP.NET.Firstly,Siemens 200 Smart PLC and paperless recorder are used to develop the monitoring and acquisition system of the underlying lower computer,which is connected to the communication network by wired communication.The local monitoring system is developed and studied by King SCADA3.70,a product of Beijing Asian Control Technology Co.,Ltd.,and IOServer is used to establish the corresponding equipment to connect the underlying lower computer.The interface of the local monitoring system is developed by using the screen editor to visualize the IOServer data.The algorithm for setting the supply and return water temperature of the second network is studied and tested,and the program is compiled and embedded into the local monitoring system.The monitoring system can set the temperature of water supply and return intelligently,and complete the development and research of local monitoring system.Secondly,write SQL Server database data storage tables,according to different data to write different types of data storage tables,add timer script and data transmission script in the local monitoring system,through the King SCADA running system will remote transmission of local monitoring system data to SQL Server database,data processing and backup;C#language is used to develop the remote monitoring system through Visual Studio tools,and the front end of the webpage monitoring system is developed according to the monitoring process of the local monitoring system.SQL Server query statement is used to synchronize the data between the webpage and the SQL Server database in real time.Then through the We Chat developer tools to develop We Chat mini program easy version monitoring system to remote monitoring system for mobile remote monitoring system reprint.Finally,the remote monitoring system is put into trial operation in the demonstration project of solid energy storage and heat storage of Hebei University of Architecture and Engineering,and the operation data are collected.According to the real-time data of the remote monitoring system,it can be seen that the remote monitoring system has good monitoring effect.The calculation and analysis of the secondary return water temperature of the heating system are carried out,and the intelligent control program is used to automatically set the secondary return water temperature of the system.
