Museum environmental monitoring system based on wireless sensing network
The invention provides a museum environmental monitoring system based on a wireless sensing network. The system comprises intelligent sensor nodes used for monitoring a museum environment factor, base stations, a control center and a terminal display device. The intelligent sensor nodes and the base stations connect into a wireless sensor network. The base stations are in serial communication with a host computer of the control center. The intelligent sensor nodes comprise a museum environment factor sensor, an information acquisition controller, and a wireless communication module. The information acquisition controller connects with the museum environment factor sensor. The information acquisition controller connects with the wireless communication module. The wireless communication module connects with the wireless sensor network. The intelligent sensor nodes have a self check mode. The system has the following advantages that: based on the wireless sensing network, on line monitoring and management of the museum environment factor are realized; the system employs an energy efficient three level information processing mechanism, the intelligent sensor nodes are provided with the self check mode, power consumption is small, and efficiency is high.
