A water supply network status monitoring method and device based on water pressure sampling data

Abstract

The invention discloses a water supply network condition monitoring method based on water pressure sampling data. The water supply network condition monitoring method based on the water pressure sampling data comprises the following steps of (1) acquiring the water pressure sampling data at one point in a water supply network, and adopting a moving average filter method for filtering the water pressure sampling data to obtain water pressure filter data; (2) comparing the water pressure filter data and a preset water pressure threshold value for judging a water supply network condition. Correspondingly, the invention further discloses a water supply network condition monitoring device based on the water pressure sampling data. The water supply network condition monitoring device based on the water pressure sampling data comprises a buffer module, an accumulation module, a comparison module and an output module connected sequentially. The water supply network condition monitoring method and the water supply network condition monitoring device based on the water pressure sampling data provided by the invention can be used for real-time judging and outputting the water supply network condition, so that an output result is more accurate, the operation processing complexity is reduced, the data processing capacity is less, the matched hardware cost input is less, and a real-time effect is good.

Description

technical field [0001] The invention relates to the field of state monitoring of water supply pipe networks, in particular to a method and device for state monitoring of water supply pipe networks. Background technique [0002] The water supply network is an important infrastructure for urban construction. Once a leakage accident occurs, it will not only affect the normal production and life, but also waste a lot of water resources. Therefore, it is imperative to discover and understand the location of the accident and the size of the leakage in time, take corresponding remedial plans to control the leakage of the pipe network, and strengthen the management of water supply facilities to rationally utilize water resources. [0003] Nowadays, most cities use the passive leak detection method to detect the leakage of the water supply pipe network, that is, to rely on full-time personnel to inspect leaks and users to report leaks. This method is not only labor-intensive and tim...

Problems solved by technology

However, at present, the output results of water supply network status monitoring based on water pressure sampling data are not accurate enough. In addition, the computational complexity is high, and the data processing volume is large, resulting in a large investment in matching hardware costs and poor real-time results.
