Audio bird dispelling device

Abstract

The invention discloses an audio bird dispelling device, which comprises external devices, a main controller, a USB storage circuit, an audio conditioning and control circuit, a display screen and keyboard circuit, a light sense and clock circuit, a serial communication circuit, and a power supply circuit, wherein the external devices comprise a U disc, an audio output terminal and a communication or detection device; the main controller is used for processing data and coordinating a microprocessor of each circuit connected with the main controller; the USB storage circuit is connected with the U disc and reads audio data stored in the U disc; the audio conditioning and control circuit is connected with the audio output terminal and is used for conditioning and filtering audio signals and finishing terminal selection and volume adjustment; the display screen and keyboard circuit is used for man-machine interface display and parameter setting; the light sense and clock circuit is used for detecting the luminance brightness and providing a real-time time reference; the serial communication circuit is connected with the communication or detection device and is used for finishing control command signal conversion; and the power supply circuit is externally connected with a power supply device and is used for supplying electricity to the microprocessor and the circuits. The audio bird dispelling device can receive commands remotely and can produce sounds randomly with randomly changed volumes, and sounds stored in an audio library can be updated in time, so the audio bird dispelling device can slow down the adaptability of birds to the utmost extent.

Description

technical field [0001] The invention relates to the field of agricultural intelligent equipment, in particular to an audio bird repelling device suitable for farmland and fruit forest applications. Background technique [0002] At present, audio frequency bird repelling is a technical means often used in the existing bird repelling technology. This type of device is usually composed of a main control system, a memory, a detection system, an audio alarm system and a power supply system. The main control system triggers an action according to the signal of the timing circuit or the real-time detection signal of the detection system, and the audio alarm system plays the audio file pre-stored in the memory in a specific way. The audio file is usually the scream of a bird or beast. The sound of natural enemies of birds and beasts, or the sound of guns, drums, and human coaxing. The utility model patent application with the patent number ZL00207081.2 discloses a bird repelling de...
