Abstract

The invention relates to an intelligent sleep electric-control low-energy-consumption wireless sensor network sound localization node which comprises a collection module, a data processing module and a wireless module. The signal collecting module converts sound signals in the physical world to digital signals capable of being recognized by the data processing module, the digital signals are sent to the data processing module connected with the signal collecting module, and the data processing module analyzes and stores the digital signals sent by the signal collecting module and exchanges analysis results with peripheral nodes through a wireless transceiving module. The data processing module can locate and track a sounding object through data collected by the collecting module of the node, and the sounding object also can be located and tracked through information exchanging of the nodes. A high-performance controller is used for achieving highly intelligence of the node, and low-energy-consumption and high-precision clock synchronization is realized combining with independent research and development of a hardware platform.

Description

technical field [0001] The invention relates to the field of sensors, in particular to an intelligent dormant electric control low-energy-consumption wireless sensor network sound localization node. Background technique [0002] At present, WSN is developing in the direction of Embedded Web Sensor, and it is also a research hotspot. Most existing and mature sensors only have the ability to collect and collect data independently. The practical application of network transmission, wireless transceiver, clock synchronization, and node energy-saving control is still in the research stage, and there is still a certain distance from mass production applications. At the same time, due to the application background and device characteristics of sensor nodes, energy consumption control has become an urgent technical problem to be solved. [0003] The diversification of wireless sensor network applications makes time synchronization a key basic service, and also puts forward many di...
