Cultural Relic Protection System Based On ZigBee And WiFi

As one of the four ancient civilizations in the world,China has many kinds of cultural relics,and how to protect cultural relics is a complex and arduous task.In order to protect the cultural relics in real time and effectively,a new kind of cultural relic protection system based on wireless sensor networks and multi-sensor is proposed.The system uses temperature and humidity sensors,ultrasonic sensors,infrared sensors,smoke sensors,environment and cultural relics collection status information,information transfer information collection node through the wireless sensor network,realize the monitoring of temperature and humidity measurement,distance monitoring,relics of the human body infrared monitoring,gas concentration monitoring function.When the temperature and humidity of the environment is protect cultural relics and the emergence of mutations of harmful gases,change the position of foreign body and cultural relics close,the system will send alarm information,realize the function of protection of cultural relics of the comprehensive and efficient real-time and reliable.The cultural relic protection system consists of three parts: ZigBee wireless communication network,cultural relic protection system,ARM gateway and host computer.The ZigBee wireless communication network composed of four ZigBee terminal node equipment(four terminal node equipment were equipped with a smoke sensor,a human body infrared sensor,a humidity sensor and an ultrasonic ranging sensor),a coordinator which realizes the surrounding environment in gas concentration monitoring,infrared monitoring temperature and humidity monitoring,and distance monitoring function.The ZigBee coordinator through the serial port connected with the ARM gateway,so as to realize the ARM module through the WiFi data collected by sensors is transferred to the cloud server,and the ARM processor through the ultrasonic ranging sensor to judge whether the mobile distance value of cultural relics,if cultural relics move,the relevant user notification messages sent through the GSM module.Finally,by using the HTTP program written by C# to access the cloud server through the protocol,the function of remote monitoring of cultural relics is realized.
