Abstract

The utility model relates to a wireless domestic animal-stealing prevention device. The device comprises a signal emission device and a signal reception/alarm device. In the signal emission device, a NOT-gate circuit collects a signal and transmits the signal to a coder, the coder codes the signal and then transmits to an emission head which further transmits the signal. In the signal reception/alarm device, a reception head receives the signal and then transmits the signal to a decoder, the decoded signal is processed by the NOT-gate circuit and then transmitted to an alarm, and the alarm automatically gives an alarm if no signal is received. The wireless domestic animal-stealing prevention device realizes the wireless alarm within a certain range. The signal emission device is put on around the neck of a domestic animal and the signal reception/alarm device is placed indoor. Once the signal emission device on the neck of the domestic animal is removed or the signal emission device is moved beyond the preset range, the indoor signal reception/alarm device automatically gives the alarm with easy and reliable use. The device can accurately alarm within a radium range from 0 m to 50 m.
