The invention discloses a sound control electronic rat control circuit which comprises a storage battery G1, a detection coil L1, a resonant capacitor C1 and a transistor T1. A positive electrode of the storage battery G1 is connected with an emitting electrode of the transistor T1, a negative electrode of the storage battery G1 is connected with a switch S1 in series, the switch S1 is connected with a tap of the detection coil L1, one end of the detection coil L1 is connected with a base electrode of the transistor T1 through a capacitor C2, the other end of the detection coil L1 is connected with a collector of the transistor T1, the resonant capacitor C1 is connected to the two ends of the detection coil L1 in parallel, a capacitor RP1 is arranged between the tap of the detection coil L1 and the base electrode of the transistor T1, and a current limiting resistor R1 is connected to the base electrode of the transistor T1 in series. When the detection coil runs into an underground small metal object, the sound frequency of a loudspeaker of a semiconductor receiver becomes higher, the small metal object can be rapidly found, and the good application prospect is achieved.
Description
technical field [0001] The invention relates to a sound-activated electronic mouse repelling circuit, which belongs to the technical field of electronic circuits. Background technique [0002] It is necessary to install anti-rodent nets on the power distribution cabinet to prevent rats from entering the station. It is easy to prevent mice from entering the power distribution cabinet and biting cables and other electrical equipment. However, the installation of anti-rat nets is cumbersome, costly, and labor intensive It is large, wastes a lot of manpower and material resources and is prone to omissions, and the effect is not good. Moreover, the use of rat poison, mouse traps, and sticky mouse boards in substations is not environmentally friendly, causing a certain degree of environmental pollution. How to overcome the above problems is the current Urgent problems. Contents of the invention [0003] The purpose of the present invention is to overcome the problems in the pri...
