Embodiment Construction
[0026] See figure 1 with figure 2 . The liquid leakage detection and positioning system of the present invention includes: a power supply 1, a metal wire 2, a state detection resistor R1 and a voltage acquisition processor (not shown in the figure). in:
[0027] The power supply 1 is mainly used to provide power. The power supply preferably adopts a constant current source. There are two metal wires 2, which are set independently of each other. The resistance value per unit length of the metal wire 2 is constant, so as to calculate the position of the leakage point. The metal wire 2 can be a bare metal wire, or a conductive rubber can be covered on the metal wire, so that when the liquid leaks, the two metal wires can be short-circuited at the leak. In this specific embodiment, conductive rubber is preferably coated on the metal wire to prevent oxidation and corrosion.
[0028] The signal line and the two metal wires are placed in the same detection cable and laid along...

The invention discloses a liquid leakage detecting positioning system, which aims to be simple in structure and convenient in use and can realize unattended operation. The liquid leakage detecting positioning system comprises a power source, two metal wires, a state detecting resistor and a voltage acquisition processor, wherein the power source, the two metal wires and the state detecting resistor are sequentially connected by signal wires and form a loop, the two metal wires with fixed resistance per unit length are mutually independently arranged, and the voltage acquisition processor is connected with two ends of the state detecting resistor, acquires first voltage of the two ends of the state detecting resistor, is connected with two ends of one of the two metal wires and acquires second voltage between the two ends of the connected metal wire. The liquid leakage detecting positioning system can be used for leakage detection of conductive liquid.
Description
technical field [0001] The invention relates to liquid leakage detection, in particular to a liquid leakage detection and positioning system capable of locating leakage positions. Background technique [0002] The effective use of liquid energy has always been a social concern, such as how to save water resources. However, in the storage, transportation and utilization of liquid resources, various degrees of waste often occur. Equipment aging, equipment damage, natural disasters and other irresistible reasons can cause liquid leakage. If a warning signal can be given when the leakage first occurs, the loss can be minimized. [0003] The current liquid leak detection methods mainly include the following: [0004] The leakage detection of water pipes mainly installs hydraulic gauges at the joints of the pipelines, and uses the hydraulic pressure difference on the hydraulic gauges at both ends of the pipeline to determine whether the pipeline is leaking. The disadvantage is t...
