Remote Sensing Monitoring And Control System Based On Multi - Network Fusion Technology

"The Internet of Things" is a combination of computer technology, wireless network technology and smart sensing technology, which is quietly changing our lives. "The Internet of Things" is also the world’s third major change of information industry after computer technology and the Internet. Based on the strong market demand, this paper is to design a smart sensor information collection network and remote control system, which is based on Multi-network integration,to complete automatic information acquisition and remote control.The system consists of ZigBee sensor information collection network, gateway system, mobile radio communication network, GPS network, server and client. Physical quantity of sensors is timing monitored by the sensor network, transmitted to the remote control center, and real-time displayed on the client. The client can online configure the sensor network and real-time change the monitoring parameters. The system also integrates a GPS chip to real-time locate geographic location of nodes. The system carries out real time detection quantity or monitoring through ZigBee sensor network, and so efficient control commands and data transmission protocol are defined, to control the network node and collect physical data. By running Linux operating system on ARM,we completed the data format conversion between ZigBee wireless communication systems and mobile radio communication network. For the Client, user interface is developed based on the Qt framework, though which we can issue orders in real time and monitor the topological structure and location relationship of nodes. The system has strong commonality and is multipurpose. By changing the network attached sensor, we can change the system uses. The experimental system mounts five types of sensors for different purposes, the experimental results show that the system can respond to user commands correctly and accurately collect sensor data, and effectively managed in the database. The system runs in good condition.
