Intelligent water meter with water leakage preventing function

Abstract

The invention discloses an intelligent water meter with a water leakage preventing function. The intelligent water meter comprises a hardware system and a software system, and the hardware system comprises a mixed signal controller, an IC (integrated circuit) card, an IC card interface, a liquid crystal display, an electric-control valve control interface, a water quantity collecting and monitoring component, a driving motor and an acoustic alarming circuit; the software system adopts modular processing and is composed of main control programs and functional sub programs, and the main control programs include system initialization, state judgement, flow pulse and water consumption processing, alarm prompting and low-power-consumption mode processing; the functional sub programs include an interface module of the IC card, a power source detection module, a flow monitoring module, a flow judging module, a time monitoring module, a charging processing module and a valve control module. The intelligent water meter integrates prepayment, gradient water charging, fault detection, the alarming function and the water leakage preventing function.

Description

technical field [0001] The invention relates to the field of automatic control of waterworks, in particular to an intelligent water meter with the function of preventing running water. Background technique [0002] With the rapid development of social science and technology, the shortage of resources is becoming more and more serious, especially water resources, which are closely related to human survival. Water is a precious environmental resource and an important material basis for my country's sustainable development strategy. However, my country is one of the countries with very poor per capita water resources in the world. Saving and protecting water resources is a very important strategic measure for our country at present. [0003] As the degree of urbanization is getting higher and higher, taking medium-sized cities as an example, about one million households cannot live without water. However, after investigation, many residents often have water leakage in their ho...
