Research On Environment Monitoring System Of Archives Based On Double Communication Mode

Archives are valuable non-renewable cultural resources for human beings.The archives warehouse is the institution that collects,keeps and manages archives and is the main body of archives.Therefore,the environmental management of archive warehouses is very important,and the longevity of archives is closely related to the environmental conditions of archive warehouses.The traditional archive storeroom adopts a manual duty model,which has low management efficiency and poor security.With the rapid development of computer technology and network technology,simple application software based on PC has appeared on the market for monitoring the environment of archives and warehouses.However,the functions of these application software are relatively single,limited by space and time,and lack of real-time and flexibility.Based on the above problems,a remote warehouse environment monitoring system based on dual communication mode was designed in this thesis.According to different application scenarios,the system communicates with the monitoring module through Modbus TCP or Modbus-RTU serial bus in real time.Dehumidifier,air conditioner and other environmental equipment status real-time monitoring,and use SQL Server to save and centralize the data collected by the monitoring module in real time At the same time,the system receives the live monitoring video stream from the video acquisition module via TCP/IP,and uses FFmpeg,VLC,QWebView and other technologies to analyze it in real time and play it on the PC.Managers can understand the environmental conditions on the spot of the warehouse in real time through the environmental parameters and on-site monitoring video displayed on the PC.When the environmental parameters of a certain area of the warehouse are abnormal,the system will start an alarm mechanism,and the PC client sends control instructions to the control module of the lower computer to perform corresponding abnormal handling.Because the system is based on a dual-communication mode environmental monitoring system,compared with the single function of the traditional environmental monitoring system of archives,it has good real-time performance and high portability,meets the needs of scenarios in different environments,and breaks through time and space Limitations.In this system,C/S structure mode adopted,SQL Server as the database server and C++as the programming language used,develops under the highly portable Qt development platform.The overall design of the system is divided into hardware parts as the server;PC client system as the client.After testing,the system has high stability and good real-time performance,with a visual human-computer interaction interface,reasonable layout,centralized display of various functional modules,and flexible use,which can achieve real-time monitoring and control of the warehouse environment.
