Abstract
The upper computer communication operation state automatic monitoring system is mainly used to remotely monitor the equipment, obtain various parameter indexes in the operation process of remote equipment, realize remote monitoring and fault diagnosis, and improve the management efficiency of decentralized equipment. This paper completes the design of communication, data storage, query, and other subsystems of upper and lower computers. The lower computer establishes a data channel with the OPC server through the MPI protocol and uploads the collected data to the OPC server in real time. The upper computer reads the data through the OPC server and displays the changes of monitored parameters in real time through the monitoring interface, so as to give an alarm under abnormal conditions. In addition, since the default database of Kingview is access, considering that the Microsoft Access database can store up to 2G of content, in order to upgrade and expand the subsequent system, SQL Server database is selected for data query, backup, and saving. The parameter setting method of communication control system is analyzed, the simulation model of industrial boiler control system is established by using Matlab/Simulink, and the interface between host computer software (IBCCS-e) and the model is provided. This paper analyzes the results of communication parameter adjustment. The simulation results show that the industrial boiler computer control system (IBCCS) has stable performance, low cost, convenient operation, and good maintainability. After further improvement, it has certain application value in the operation transformation of new small- and medium-sized boilers and original boilers.
Highlights
With the continuous expansion of the operating scale of industrial enterprises, only realizing the control of various field devices can no longer meet higher requirements, and the real-time response to the working conditions of the field devices has more practical significance [1]
As the company’s on-site environment is becoming more and more complex, and the targets to be monitored are more diverse, the structure of the monitoring system becomes more and more decentralized. e traditional programmable logic device to directly control field devices can no longer meet the decentralized requirements of the system topology [2]
Is paper studies the overall architecture of the host computer communication operation state automatic monitoring system, provides a reasonable solution according to the specific situation of this paper, analyzes the network topology and architecture of the wireless monitoring system, determines the selection of measurement parameters, and identifies the radio wave propagation characteristics and signal maintenance methods of the communication system
