The working principle of underground water detection is based on acoustic vibration detection, which is a method of locating leaks by capturing and analyzing the acoustic signals generated when a water pipe leaks. When a water pipe leaks under pressure, water escapes from the point of breakage at a certain speed due to the pressure difference between the inside and outside of the pipe, and vibrations are generated as a result. This vibration travels along the pipe in the form of fluctuations and can be captured by specialized sensors.
Underground water detection collects and analyzes the sound and vibration signals generated at the point of leakage by means of built-in sensors. Since sound signals are affected by distance, medium and other factors in the propagation process, the closer the leak, the higher the relative proportion of high-frequency part of the energy, the sharper the sound will sound; and the farther away from the leak, the faster the high-frequency part of the attenuation, the sound will sound more muffled.
underground water detection processes the collected sound signals and displays them on the screen of the host computer in the form of visualized spectra and signal columns, and also outputs the sound signals to the operator through headphones. The operator can analyze and judge the sound signal by combining "listening" and "looking" to determine the exact location of the water leakage point.
The application of underground water detection requires a certain amount of experience, because in the actual detection process, in addition to the sound of water leakage, it may also be interfered by other environmental noise, such as footsteps, traffic noise, etc. Therefore, the operator needs to have the ability to recognize the sound of water leakage. Therefore, the operator needs to have the ability to recognize and filter useful information in order to improve the accuracy and efficiency of detection.
The use of underground water detection also requires attention to some details. For example, during the detection process, a relatively quiet environment should be chosen to reduce the interference of environmental noise; at the same time, the operator should master the use of the instrument to ensure that the sound signal can be correctly captured and analyzed.
Underground water detection is a kind of water leakage detection equipment based on acoustic vibration detection principle, which locates the leakage point by capturing and analyzing the acoustic signals generated by the water pipe leakage. In practice, it requires operators to have a certain level of experience and technology to ensure the accuracy and efficiency of the detection.
