If the first voltage acquisition end of the processor acquires the voltage within the preset time, the processor controls the second output end of the power generator to output the second voltage when acquiring the voltage; if the first voltage acquisition end of the processor does not acquire the voltage within the preset time length, the processor controls the second output end of the power generator to output the second voltage after the preset time length. After the processor controls the second output end of the power generator to output the second voltage, the first voltage acquisition end of the single chip microcomputer in each detection device acquires the third voltage, the voltage changes twice, namely j is 2, and since K is 2, namely j is K, of the 2 nd detection device, the 2 nd detection device controls the second switch K at the moment22And a third conductive line L23Is connected to the first end of the first connecting lead C12A second switch K12A second conductive line L12A second connecting wire C22A second switch K22A third conductive line L23A first switch K21Conductive wire coating A2A first lead L11A first switch K11A first connecting wire C11And a second resistor R2 to form a circuit loop if the conductive wire is coated with A2If the circuit is not broken, the second voltage acquisition end of the processor acquires voltage, and at the moment, the 2 nd pipe section can be determined not to have water leakage, if the conductive wire coating A2And if the circuit is broken, the second voltage acquisition end of the processor cannot acquire voltage, and the 2 nd pipe section can be determined to have water leakage. In additionAnd when the water supply pipeline is a metal pipeline, an insulating coating is coated between the metal pipeline and the electric wire coating. The water supply pipeline may be buried underground. The conductive wire coating is a linear conductive layer which has a conductive function and is coated on the pipe section. The first switch, the second switch and the third switch in the present invention may be single pole double throw switches.
According to the embodiment, the water supply pipeline is divided into the plurality of pipe sections, the outer surface of each pipe section is wound with the continuous conductive wire coating, the first connecting lead and the second connecting lead are correspondingly arranged for each conductive wire coating, the conductive wire coatings of every two adjacent pipe sections are disconnected, and the detection device is arranged between every two adjacent pipe sections, so that the integral water leakage detection and the water leakage detection of each pipe section can be realized; in addition, the invention controls the first switch and the second switch by switching the voltage output by the power generator, so that the single chip microcomputer in each detection device controls the first switch and the second switch based on the acquired voltage, and designs the control logic, and can realize that each single chip microcomputer controls the corresponding first switch and the second switch to act in sequence without the help of a wireless network, thereby realizing the detection of the water leakage condition of each pipeline in sequence.
