Traditional Chinese Infrared controlled electronic cat: Circuit Design, Parts List & Workshop Prototype Guide
In short: Traditional Chinese Infrared controlled electronic cat. This entry documents a circuit & prototype taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 5368 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Infrared controlled electronic catRat pests have become a disaster in various parts of our country, causing great losses to the country and people. "Cats can avoid mice" is an objective fact. Wherever there are cats, mice are rare or even extinct. However, if every household keeps a cat to avoid mice, it will cause cat harm. If you make an electronic cat and use simulated cat sounds to drive away mice, it is effective. However, regardless of whether there are mice or not, the electronic cat will always bark, which will disturb the tranquility of the surrounding environment.The characteristics of the infrared controlled electronic cat introduced in this article are: when mice appear in the protected area, the electronic cat chirps; when no mice appear in the protected area, the electronic cat does not chirp. In this way, the purpose of cats being able to avoid mice is achieved, and interference to the surrounding environment is avoided.1． How the circuit worksThe circuit of the infrared controlled electronic cat is shown in Figure 55-1. It is composed of an infrared transmitter, an infrared receiver and a cat sound simulation circuit. alt="55-1a.jpg (14606 Byte)">Figure 55-1(a)(a) in the figure is the infrared emission circuit. It is a self-excited multivibrator composed of a time base circuit IC. The oscillation frequency is about 38kHz. Since the oscillation pulse duty ratio is high, about 15:1, the current limiting resistor R3 of the infrared emission tube LED has a small resistance, and its purpose is to obtain larger pulse power.(b) in the figure shows the infrared receiving circuit and cat sound simulation circuit. The infrared receiving tube BG1 receives the infrared emission signal, which is amplified by BG2, and then frequency selected and demodulated by BG3. Its output signal voltage triggers BG4 to turn on, and BG5 to turn off. The power supply of the cat sound simulation circuit is blocked, and no meowing sound is emitted from the speaker. …
