The detection host comprises an audio acquisition circuit, a gas acquisition circuit, a conductivity acquisition circuit, an MCU controller, a display driving circuit and an earphone driving circuit. The conductivity probe can adopt an FH-S303 conductivity probe and can also be replaced by a water leakage sensor, the working principle of the water leakage sensor is based on the change of conductivity, and when a water pipe leaks water, the water flows out and contacts an electrode on the sensor, so that the conductivity is changed.
The working principle of the embodiment is as follows:
as shown in fig. 3, when the water leakage detection is performed on the pipeline to be detected, a power switch and a noise reduction switch of the detection host are turned on, when the detection is performed through the sound sensor probe, the sound sensor probe detects the vibration signal value on the pipeline pickup node, after the sound sensor probe transmits the vibration signal value to the detection host, the detection host logically processes the vibration signal value through the audio acquisition circuit and converts the vibration signal value into an audio signal and transmits the audio signal to the MCU controller, and if the audio signal detected by the MCU controller is higher than a set value, the MCU controller sends signals to the first alarm and the second alarm to perform water leakage alarm reminding for a user. Meanwhile, the MCU controller outputs an audio signal to the human ear through the earphone driving circuit to identify the sound size of the water leakage point, and displays a signal waveform curve on the display screen, so that a user can intuitively judge the position of the water leakage point according to the sound and the waveform.
When the gas sensor probe detects, the pipeline is emptied, trace gas (hydrogen-nitrogen mixed gas, wherein nitrogen is 95% + and hydrogen is 5%) is injected into the detected pipeline, the trace gas which can be identified by the gas sensor probe leaks out through pressurization, the gas sensor probe identifies the area behind the approximate area of the trace gas leakage point, then the ground of the suspected leakage area is perforated to the pipeline burying depth, the detected trace gas is enabled to rise straight, and the effect of accurately positioning the leakage point is achieved. After the detected gas signal is transmitted to the detection host by the gas sensor probe, the detection host processes the detected gas signal through the gas acquisition circuit, converts the detected gas signal into digital gas concentration and transmits the digital gas concentration to the MCU controller, if the gas concentration detected by the MCU controller is higher than a set value, the MCU controller sends signals to the first alarm and the second alarm to perform water leakage alarm to remind a user, the signals are displayed on the display screen, and the user can judge the position of a water leakage point according to the size of the gas concentration.
When the detection is carried out through the conductivity probe, when water leakage occurs in the pipeline, water flows out and contacts with an electrode on the conductivity probe, conductivity is changed, the conductivity is transmitted to the detection host through the conductivity probe, the detection host converts the conductivity into an electric signal through the conductivity acquisition circuit and transmits the electric signal to the MCU controller, and if the electric signal detected by the MCU controller is higher than a set value, the MCU controller sends out a signal to the first alarm and the second alarm to carry out water leakage alarm, and the signal is displayed on the display screen.
The embodiment can select probes to be detected according to specific environments or combine the results of the three probes, so that misjudgment is further reduced, and compared with the existing detection instrument with single detection form, the embodiment is convenient to use and can effectively reduce the error rate of water leakage detection.
