Design of System for Digital Sound Anti-monitoring Based on Wireless Sensor Networks and 3G

This paper introduces a control system. This system consists of wireless video transmission module, wireless data transmission module, voice and ultrasonic anti-bird module, field of environmental parameters detection and infrared anti-theft alarm module. Host of the system receives the control signal issued by the long-distance computer, controls voice and ultrasonic, and also collects data of video, images, and environmental parameters. 3G network is connected to the host computer. As a result, the system can monitor the information of bird pest, use a variety of modes to scatter birds, also provide remote expert diagnosis with the gathered information about growth of crops.
