Abstract

The invention belongs to the technical field of instrument detection, and provides an anti-interference detection method, circuit and electronic equipment for leak detection equipment, wherein the anti-interference detection method for leak detection equipment comprises the steps of: selecting a frequency band for a collected input signal , obtain a target frequency segment, the input signal includes an audio signal and a display signal; amplify the audio signal of the target frequency segment through the first branch and output the target audio information, and convert all the target frequency segment. The display signal is amplified by the second branch and then outputs the target display information. The invention achieves the effect of improving the anti-interference ability of the environment by selecting the frequency band of the collected input signal according to the on-site environment; and divides the input signal into two independent signals and processes them through two independent branches to prevent the interference between the signals. Mutual interference, thereby improving the electromagnetic anti-interference ability of the instrument itself, ensuring the authenticity of the audio signal, thereby improving the accuracy of the instrument test.

Description

technical field [0001] The invention belongs to the technical field of instrument detection, and in particular relates to an anti-jamming detection method, circuit and electronic equipment for leak detection equipment. Background technique [0002] Today, the workshops and installations of cities and enterprises have complex processes and dense pipelines. Various types of integrated pipelines are buried underground, such as water supply pipelines, circulating water pipelines, drainage pipelines, oil discharge pipelines, material pipelines, etc., just like capillaries in the human body, which are densely packed and criss-crossed to form their own networks. The pipelines are laid underground, and their repair and maintenance are the top priority. However, according to the existing technology and process, how to judge whether the water supply pipeline is damaged and leaking, where is the leaking point, and what is the water leaking condition can only be judged by experience. T...
