Soft-start birdhouse automatic exhaust system based on bias amplify circuit

Abstract

The present invention discloses a soft-start birdhouse automatic exhaust system based on a bias amplify circuit, and the system is characterized by mainly consisting of an exhaust fan M, a detection circuit, an amplifier P1, an amplifier P2, the bias amplify circuit connected with the detection circuit, a capacitance C3, a capacitance C4, etc.; the negative pole of the capacitance C3 is connected with the positive pole of the amplifier P1, and the positive pole is connected with the bias amplify circuit; and the negative pole of the capacitance C4 is connected with the output terminal of the amplifier P1, and the positive pole is connected with the positive pole of the capacitance C3 though a resistance R4. The system can filter interference signals from a detection signal, increase the cleanliness of the detection signal and amplify the detection signal without distortion, thereby making the exhaust fan under more accurate control while it is in motion, ventilating the birdhouse more effectively, improving the quality of the air inside the birdhouse and furthermore facilitating livestock breeding. The system has soft-start function for protecting electronic components from surge current well.

Description

technical field [0001] The invention relates to the field of poultry breeding, in particular to a soft-start poultry house automatic exhaust system based on a bias amplifier circuit. Background technique [0002] The environmental status of the poultry house is closely related to the health of the livestock. If the environment of the poultry house deteriorates, the incidence of livestock disease will increase, especially in a high-density or closed breeding environment. Due to poor ventilation, the ammonia inside the poultry house will The high concentration of gas has a particularly serious impact on livestock. In order to reduce the concentration of ammonia in the poultry house, farmers usually use an automatic exhaust system to ventilate the poultry house to improve the air quality in the poultry house. However, due to the influence of interference signals, the existing automatic exhaust system has a high rate of malfunction and cannot effectively ensure the quality of t...
