The Hardware And Software Design And Realization Of Wireless Sensor Network Node's Processor Module Based On OMAP

Wireless Sensor Network is the combination technology of computer science, communication and sensor technology.It is a techonology of obtaining and processing information.The wireless sensor network uses in variety field.The network node can carry different sensor,when the node carry sensor as tremble sensor or magnetism sensor,the data to be processed is few,and the process is not complicatied,so the current wireless sensor node can satisfied the need,but in some specific field,the wireless sensor network require the node can execute complicated data processing scheme,and this can't be achieved with current node's capability of calculating and storing.This article describe that the node's working field has strong interferer and radio noise,and the signal must hard to be detected.In this case, the nodes have to use spectrum spread,and the signal can be sent with a low power,so the signal is hard to be detected.This article will introduce how to design a wireless network node which can acheive spread spectrum communication,and introduce the scheme of the node's processor module.After analyze relative documents,design the node's hardware and software,and realize the node. Results shows all required system functionalities are realized.
