Wireless remote water leakage detection device and system

Abstract

The invention discloses a wireless remote water leakage detection device and a wireless remote water leakage detection system, and relates to the field of pipeline monitoring. A wireless water pipe leakage detection device has very low power, is provided with an embedded processor with enhanced DSP function, and acquires leakage audio data at fixed intervals in a fixed time period each day; the acquired data is locally processed; and according to the continuity of the detected leakage audio signals and by combining accumulatively stored background noise level, the leakage judgment is performed, and the detection reliability is enhanced. The device is powered by batteries, has the operating time of over 3 years, and has very low average use and maintenance cost. A remote water pipe leakage monitoring system can display the operating condition of a water supply network in a visual mode in real time by adopting a GIS system of the water supply network according to the received water leakage information, and also can automatically count multiple kinds of information.

Description

Technical field: [0001] The invention relates to the field of pipeline monitoring, in particular to a water leakage monitoring system on a water supply pipeline network. Background technique: [0002] Water is the source of life. In daily production and life, water is closely connected with human beings all the time. my country is a country severely lacking in water resources. The per capita water resources are less than a quarter of the world's average level, and the geographical distribution is extremely uneven. The shortage of water resources and water pollution is in front of us. Two major subjects. Therefore, the rational development and effective use of the existing limited water resources is a top priority related to the sustainable development of the national economy. [0003] At present, there is a common problem of water leakage in the pipe network in my country's water supply industry. The average water loss rate is about 20%, and the leakage accounts for about 5...

Problems solved by technology

However, most of our water companies rely on the existing equipment to do this. They often check for leaks when they find that the ground seeps or subsides, and the water pressure drops. At this time, the pipe network may have been leaking for several days or even dozens of years. God

If things go on like this, the loss of water leakage will be very serious, which is not conducive to the macro control of water leakage

[0007] 2. Since tap water leak detection is a long-term and arduous task, relying on traditional leak detection methods requires a lot of manpower and material resources, and the work efficiency is low

The audio characteristic of this kind of water leakage is the basic principle of water leakage detection and location in underground pipelines. Therefore, it is necessary to obtain long-term stable and accurate acoustic wave detection data of valve plug
