ABSTRACT
Based on ARM micro controller introduced the sensor network node design scheme. Is given based on ARM7 series LPC2214 chips for the core of hardware design, this paper expounds the principle diagram infrared sensor circuit, rf communications circuit, peripheral interface circuit design and data transmission process. The sensor node configuration simple, expand with convenient, the reliability high characteristic. Sensor network can realize the data acquisition quantization, processing fusion and transmission applications, it is currently a hot, the information field of its academic and industrial academic value and application foreground is very promising. Automatically configured wireless sensor network can be used on a large scale collection, treatment and release complex environmental data. Wireless sensor network is the basic component unit nodes. The nodes is a miniature of the embedded system and it through carry energy limited battery or use of natural conditions, and to realize the power-supply modes, collected or receive data processing, storage or send. Each sensor node with traditional network node of the terminal and routing double function, in addition to local information collecting and processing data to other nodes, but also by the forwarding to data storage, management and fusion processing, with the other nodes to accomplish certain tasks.
