Numeric Family Application Research Based On Wireless Sensor Network

Wireless sensor network is a new technology generated with the fast development of computer technology, communication technology, electronic technology, and network technology. This new technology has been applied in some important science field. Such as national defence, military affairs, environment surveillance, scientific research, and industrial control. It is the great important with the wide application of sensor network, research about how to realize family electrical equipment management with wirless sensor network technology.First, this paper aims to wireless sensor network technology, carries out a deep research into this subject, and gives a summary of the applied characteristic of wireless sensor network. Then with analysis of theory and data tranfer way of some typical route protocol, IEEE802.15.4 protocol is suggested to construct the numeric family network for its' characteristics such as short distance communication, low energy consume, low cost, and simple topology.Second, with collection of real consumer requirement data, this paper made a detailed and colligate analysis with the numeric family market apply and requirement analysis of wireless sensor network. Then we received some requirement of cousumer in wireless network family apply, which provide reliable basis for the densign and development of numeric family apply system.Combine consumer's apply requirement with the feature of numeric family apply and the present wireless sensor network techonology, a new numeric family network structure based on IEEE802.15.4 protocol is provided.Through combineation of hardware and software, the sensor node's hardware, software technology structure, and criterion of numeric wireless network are designed.Finally, this paper used the latest chip product for the design of sensor node module and CPU, combined with IEEE802.15.4 communication protocol, designed the frame format of data transmission between sensor node module and CPU. On the base of our design, this paper used C programming language to realize data communication on MAC layer, and completed the data communication among the wireless net nodes in family aplly. Moreover, it accomplish upper levels software development of numeric family network system with the pop and stable operation system, database system, and the middle component. During the course of the design, we adopted standardization design to modules so that it can be a commonly used model to be popularized in the market.
