Guangxi Archives Warehouse Temperature And Humidity Control System

Archives in specific environment is keeping, environmental conditions on the service life of the archives impact, the storage environment in the file, temperature and humidity is the most fundamental and most important influence factors of suitable environment temperature and humidity can not only delay the ageing of the material made of archives, and be able to curb environmental factors in other of archives for effective role of archives warehouse environment temperature and humidity control, make the Chambers archives to attain and maintain safe storage conditions in this system on the industry mature advanced monitoring control means of introduction to warehouse environment monitoring project system, to improve the level of our country’s file custody protection technology is of great significance.This subject adopts advanced computer technology digital sensor technology and intelligent transmitter technology to design the GuangXi archives warehouse temperature and humidity control system PC using a monitor computer and a database server and a unit under into masterslave distribution structure, the machine adopts a collection of high performance/price ratio, temperature and humidity sensor and control module, mainly to achieve environmental parameters in warehouse data acquisition and control equipment work according to the archives warehouse layout wiring characteristics, use of the most common common half-duplex RS-485bus for communication mode, like this is advantageous to the economy of the system operation and maintenance of the versatility wiring convenience. This topic GuangXi archives warehouse of temperature and humidity monitoring system in the choice of temperature and humidity control module selection, monitoring of the values of the temperature and humidity warehouse principle and realization method of temperature and humidity control warehouse, and many other aspects of research and design system using object-oriented programming technology and through VB6.0Access database design software is developed, and the friendly human-machine interface interaction of monitor host software development, realize the value and the operation temperature and humidity data read inside storeroom dehumidifier and the operation of the equipment according to obtain the temperature and humidity of the data value, form the history of each warehouse reports, statistics a monthly (years) of the highest temperature and humidity minimum temperature and humidity value and average value of temperature and humidity value; Monthly statistics (years) overran days, and the number of qualified, fan and air dehumidifier operation situation of and running time and so on related content. The system also realized the temperature humidity inside storeroom two warehouse environment parameters of management and consultation, according to the control strategy of the realization of automatic control equipment fan and the operation of the humidity conditioner off, achieve automatic control warehouse demands of the environment temperature and humidity on the upper also set a WEB sites, in the archives LAN through the IE browser for graphics display and visualization inquires.At present, the system in the guangxi zhuang autonomous region of archives work well.
