The Research Of Monitoring And Control System Based On WSN

The voice signal extraction and processing of ubiquitous computing technology is a key technology. It is an application system, and use the environment in the context of information to take the initiative to provide customers with mission-related information and services. It has a wide range of applications in Human-Computer Interaction and automatic processing of information areas.Wireless sensor network is a new kind of self-organizing networks. Tens of thousands of sensor nodes can be randomly deployed in the target area and in the form of self-organizing network. It can capture real-time information about the target area and save them in an internal network or use the gateway to send them to the terminal management. It makes the world's natural and human world more closely together. It has a wide range of applications in the military, medical, astronomy and other fields.Traditional voice signal extraction techniques are a number of sensor nodes to achieve independence. And based on this paper, wireless sensor networks provide to achieve the sound signal extraction new ideas. In this paper, the use of wireless sensor networks have unique advantages to achieve the sound signal extraction and transmission, data fusion technology to achieve the context of information, collate and integration. Coordination mechanism deals with the use of sensor nodes between collaboration so that the context of information flow and processing. First of all, the sound sensors and wireless sensor network node mica2 combination of the voice signal extraction. Then use a new type of wireless sensor network operating system SOS which is based on the related routing protocols to transfer voice data in all nodes. Finally, make use of wireless sensor networks to monitor the dynamic changes in the voice signal and design a set of interface management software to give effect dynamic maps so that the voice signal can be saw effectively.
