Problems solved by technology

[0002] The existing engineering leakage monitoring theory and method mainly estimates the seepage velocity at the leakage location based on the temperature measurement, but requires many input parameters for calculation, which makes the calculation very complicated
In addition, in actual engineering, the unevenness of the material of the soil layer to be tested makes it difficult to determine these input parameters, which can neither achieve effective monitoring nor timely early warning, which brings great difficulties to practical applications

Embodiment approach

[0069] Further, as Figure 4 As shown, it is another early warning implementation mode provided by the present invention when there is leakage at a certain measuring point around the measured object, and the details are as follows.

[0070] Step S170, for each reference element in the reference space-time distribution matrix, compare the reference element with the theoretical element at the corresponding position in the theoretical space-time distribution matrix.

[0071] Step S180, judging whether the reference element is within the second threshold interval, and if so, generating early warning information and sending the early warning information to the project management terminal.

[0072] It should be noted that in step S140-step S180, when judging whether the reference element is located in the first threshold interval or the second threshold interval, if it is located, it only indicates the leakage near the measuring point, and does not represent other measuring points. ...

Abstract

An embodiment of the present invention provides a leakage monitoring method and device based on a temperature spatiotemporal distribution matrix. The leakage monitoring method based on a temperature spatiotemporal distribution matrix includes obtaining the actual temperature change values ​​around the measured object at preset time intervals to generate The measured space-time distribution matrix used to characterize the temperature change; the difference between the measured space-time distribution matrix and the theoretical space-time distribution matrix is ​​obtained as a reference space-time distribution matrix; whether the matrix elements in the reference space-time distribution matrix meet the preset value , if not satisfied, there is liquid leakage around the measured object. In the actual engineering application process, the invention can realize the effective monitoring of the engineering leakage according to the temperature change, and the method is simple and convenient to implement.

Description

technical field [0001] The invention relates to the technical field of engineering leakage monitoring, in particular to a leakage monitoring method and device based on a temperature-time-space distribution matrix. Background technique [0002] The existing engineering leakage monitoring theory and method mainly estimates the seepage flow velocity at the leakage location based on the temperature measurement, but requires many input parameters for calculation, which makes the calculation very complicated. In addition, the heterogeneity of the material of the soil layer to be tested in actual engineering makes it difficult to determine these input parameters, which can neither achieve effective monitoring nor timely early warning, which brings great difficulties to practical applications. Contents of the invention [0003] In view of this, the present invention provides a leakage monitoring method and device based on temperature space-time distribution matrix, which can effec...
