- Abstract
Aiming at micro environmental variation inside the cave of Mogao Grottoes include temperature, humidity and the concentration of carbon dioxide has significant influence to the preservation of cultural relics consist of murals, statues and so on,a set of micro environment control system were developed. The system mainly was composed of automatic partition doors and wireless transmission network. The controller based on the digital signal processor (DSP) as the core, sheer curtain, sealing curtain, shutter etc were installed on the door. By adjusting shutter's rotating angle,the air volume and wind speed into the cave were controlled. When the natural ventilation cannot adjust the cave micro environment, the method of active air supply makes temperature, humidity in the cave keep constant and decreases the concentration of carbon dioxide. Wireless transmission network consists of wireless environment monitoring sensor,wireless multi function gateway,router and F5 communication module,which realizes the cave micro environment data acquisition and auto door's remote control. The result of experiment shows that the micro environment control system has a certain effect on regulating the micro environmental temperature, humidity and the concentration of carbon dioxide.
