Research And Design Of Wireless Sensor Networks Application Platform

The wireless sensor network that mixed with the network communication technology, information processing technology and sensor technology is generalized with the development of the science. The wireless sensor network is a self-organize network that composed by a large number of sensor network nodes through the wireless communication form, based on which, the data quantificat collect, process mixture and transmission are realized. It is an economical, high-efficiency, low-data rate wireless communication network, a new development filed in modern information technology, which has a very light future.The development situation, characteristic and application filed of the the wireless network are introduced and the protocol stack of ZigBee is analyzed. The programs of the sensor data collection and communication between the nodes are designed both on the platform of ZigBee protocol stack and Tiny operating system, and successfully transplanted into the hardware platform CC2430,based on which, the sensor network composed of collect nodes and several terminal nodes is successfully organized. To fit the different application fileds, three collect methods of WSN data are put forward in the papaer.The data manager system based on the platforms Windows and WinCE is developed.Based on which, the sensor data of the collect nodes are transfromed to the data manager system and then to the server through the GSM network. Because of it, the data information can be accessed by the user through Internet.After experiment, the proposed three methods receive good performance, meet the expected goal, the results show that the wireless network has ues-value.
