[0022]In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0023]figure 1 It is a schematic diagram of the detection principle of the water leakage detection induction cable. The induction cable is a 4-core cable with positioning detection. Among them, the red A1-A1' line and the yellow B1-B1' line are signal lines with a resistance value close to zero, and the two black A2-A2' and B2-B2' lines are real leaky sensing lines with a certain resistance value evenly distributed. . The connecting wire on the left connects one end A1' and A2', B1' and B2' of the 4-core induction wire; the connecting wire on the right connects the other ends A1, A2, B1 and B2 of the 4-core induction wire to Host.
[0024]When there is a water leak, suppose the two black lines are leaking and soaking at X1-X2 in the figure. Therefore, the wate...
