The first amplitude information is the maximum amplitude value in the vibration signal, and the second amplitude information is the minimum amplitude value in the vibration signal.
For the embodiment of the present application, it is assumed that the electronic device acquires three vibration signals, namely a first vibration signal, a second vibration signal and a third vibration signal. The first amplitude information in the first vibration signal is 5V, and the second amplitude information is 5.1V; the first amplitude information in the second vibration signal is 5.2V, and the second amplitude information is 5.25V; the first amplitude information in the third vibration signal is 5.3V, and the second amplitude information is 5.36V.

And S1041, determining whether the pipeline leaks or not based on the amplitude analysis result.
Further, after the amplitude analysis result is obtained by the above-described embodiment, it is determined whether the pipe leaks based on the amplitude analysis result.
Specifically, determining whether the pipeline leaks based on the amplitude analysis result may specifically include:
and if the absolute value information is within the preset error range, determining that the pipeline leaks.

Such as 5.03V, 5.06V and 5.09V.
And S1031e, performing variance processing based on each third amplitude information to obtain variance processing results.
For the embodiment of the application, the variance is used for representing the fluctuation change of the amplitude of the vibration signal in a time domain, and the size of the variance is inversely related to the reliability of the vibration signal for representing the leakage of the pipeline. Taking the three pieces of third amplitude information in step S1031d as an example, the variance processing is performed on the three pieces of third amplitude information, and the obtained variance processing result is 0.0006V.

The preset variance interval is assumed to be 0V-0.1V. Taking the variance processing result determined in step S1031e as an example, the variance processing result is 0.0006V, which is between the preset variance ranges, so that it can be determined that the pipe leaks.
Specifically, the more the number of the sub-vibration signals obtained by equally dividing the vibration signals in the time domain is, the more reliable the obtained variance processing result is, and the more accurate the judgment whether the pipeline leaks or not is.

Assume that the fourth amplitude values corresponding to the three vibration signals are 5V, 5.1V, and 5.2V, respectively. The two pieces of fourth amplitude information satisfying the preset condition are 5.2V and 5.1V.

The sensor information includes position information of the sensor. In the embodiment of the application, when the pipeline leaks, the vibration intensity generated by the pipeline is gradually weakened along the pipeline from the leaking position, the closer the sensor is to the leaking point, the larger the amplitude of the vibration signal is, and the farther the sensor is from the leaking point, the smaller the amplitude of the vibration signal is. Taking step S107 as an example, it can be deduced that the leak point is located between the sensors corresponding to the two largest pieces of fourth amplitude information.
Specifically, the electronic device determines position information of a corresponding sensor from two vibration signals corresponding to fourth amplitude information meeting a preset condition, wherein the position information may be geographical coordinate information, information of a block where the sensor is located, number information and the like of the sensor.

For the embodiment of the present application, a ratio process is performed on two pieces of fourth amplitude information satisfying a preset condition, and taking step S105 as an example, it is determined that the two pieces of fourth amplitude information satisfying the preset condition are 5.2V and 5.1V. Referring to fig. 2, assume that the sensor corresponding to 5.2V is a and the sensor corresponding to 5.1V is B. And taking the small amplitude of the two pieces of fourth amplitude information meeting the preset condition as a numerator, and taking the sum of the two pieces of fourth amplitude information meeting the preset condition as a denominator to obtain ratio information of 5.1/(5.1 + 5.2).
