The resistance change value of the pipeline intelligent repair sensing material 2 is △R _S , and the expression is:

△R _S ＝△R _T +△R _N

In the formula, △R _T is the resistance change value caused by water temperature, and △R _N is the resistance change value caused by pipeline deformation.

The calculation formula of resistance change value △R _N caused by pipeline deformation is as follows:

△R _N ＝GF R ₀ ε ₀

In the formula, GF is the gauge factor of the sensing material for intelligent pipeline repair, R ₀ is the initial resistance of the sensing material for intelligent pipeline repair, and ε ₀ is the initial strain of the sensing material for intelligent pipeline repair.

In the above two cases, subtract the resistance value before the mutation from the resistance value after the mutation to get △R _N , and calculate the gauge factor Comparing the calculated GF value with the GF-ε curve of the cloud server 5, the strain value of the pipeline at this time can be obtained.

When the water temperature in the pipeline 1 changes, and there is no vehicle or pedestrian passing above the pipeline and the pipeline is not deformed, the resistance change of the pipeline intelligent repair sensing material 2 is only caused by the change of water temperature, and the temperature coefficient of resistance TCR of the pipeline intelligent repair sensor material 2 Therefore, select the resistance value at equal intervals, subtract the resistance value at the previous time point from the resistance value at the next time point to get △ R _T , and calculate the temperature coefficient of resistance The calculated TCR value is compared with the TCR-T curve of the cloud server 5 to obtain the water temperature at this time.

When the water level in the pipeline 1 changes, the resistance of the ring-shaped intelligent water level monitoring sensing material 10 changes, and the resistance value at equal intervals is selected, and the resistance value at the next time point is subtracted from the resistance value at the previous time point to obtain R _W , to calculate the water level coefficient of resistance The calculated K value is compared with the KH curve of the cloud server 5 to obtain the water level at this time.
