Design of sound bird-scared device based on MP3

Agricultural bird damage problem has been a hot issue trouble all the time, how to not only protect the birds but also put the economic-threat to birds under economic threshold at the same time has become the focus to the current research. The system on the basis of Intelligent Voice-driving Bird Dispeller, puts forward the STC89C58RC/RD and single-chip microcomputer as the core, including SMS module, photosensitive module, AD convert module and MP3 audio module which is composing of a portable intelligent voice anti-Bird Device. The system detects the outside light intensity by the photosensitive module, and the GSM module receives the remote control signal which is from the GSM mobile phone, the MP3 module will be controlled by the power relay, the MP3 module receives the command, then PLAY/STOP the voice on U disk, which can achieve the driving field vermin. It is proved that the system is not only easy to operate, saving costs, but also make a profound difference to drive birds with good results by the field experiment. Meanwhile, as long as changing the sound file, the device can be applied to drive rats, drive wolves and other occasions.
