Abstract

The invention discloses a leakage and pipe explosion early warning system for a city water supply network, which relates to a leakage and pipe explosion detecting and warning system for the city water supply network and belongs to the field of safety early warning. The early warning system of the invention comprises a piezoceramic acceleration sensor, a sensor signal processing circuit, a warning main control circuit, a GSM (Global System for Mobile Communications) communication module and PC (Personal Computer) monitoring software. The invention realizes the remote monitoring of accidents of leakage and pipe explosion of the city water supply network, can dynamically manage the water supply network, and has greater practical application prospect.

Description

technical field [0001] The urban water supply pipe network leakage burst warning system relates to a water supply pipe network leakage burst detection and alarm system, which belongs to the field of safety early warning. Background technique [0002] At present, the detection of leaking and bursting pipes in urban water supply pipe networks is mainly based on audio-audiometry and related calculation methods. [0003] (1) The working principle of the audiophonic method and the use of the audiometer: [0004] When the fluid in the pipeline leaks under pressure, the vibration wave generated will propagate along the pipeline or the buried medium (such as soil, cement, etc.) Pre-locate, and then use the ground listener to determine the location of the leak point directly above the pipeline, and judge on the spot based on human experience. [0005] (2) Principle of correlation calculation method [0006] In the monitoring network where the sensor monitors the state of the water...
