Abstract

The invention discloses a distributed leakage detection positioning system of a regional pipe network. The system consists of a host machine, a plurality of data acquiring devices, a plurality of sensors and a wireless communication module, wherein the host machine is electrically connected with the wireless communication module; the wireless communication module is connected with the data acquiring devices through a wireless network; the data acquiring devices are electrically connected with the sensors correspondingly one by one; the matched data acquiring devices and sensors form sensing nodes; the sensing nodes are arranged on a monitored pipe network in a dispersing way. The invention also discloses a control method based on the system. The system has the beneficial technical effects that leaking points of the pipe network in a wide region can be detected and positioned, the real-time property is good, the setting cost of the devices is low, the leaking points are intuitively positioned, and the system is convenient to maintain and repair.

Description

technical field [0001] The invention relates to a pipeline leak detection technology, in particular to a regional pipeline network distributed leakage detection and positioning system. Background technique [0002] For the detection and location of pipeline leakage points, the existing technology can only locate a single leak point on a single section of pipeline with a certain length, such as Chinese patent 96121000.1, if the existing technology is used to locate the pipeline network in a larger area When locating leaks, there are defects of poor real-time performance and high device installation costs. Contents of the invention [0003] Aiming at the problems in the background technology, the present invention proposes a distributed leakage detection and positioning system for regional pipe networks, the structure of which is: the system is composed of a host, multiple data acquisition devices, multiple sensors and wireless communication modules; The host is ele...
