Self-generating intelligent water meter based on radio frequency technology

Abstract

The invention discloses a radio-frequency-technique-based self-power-generating intelligent water meter which comprises a power supply module, at least two water quantity detection modules and a control alarm device, wherein the power supply module is connected with the control alarm device, and both the power supply module and the control alarm device are arranged in the shell; the water quantity detection modules are connected with the control alarm device, and embedded in the shell on the lower side of the control alarm device; a water inlet of each water quality detection module is connected with a user water main pipe port arranged on the shell through a branch pipeline; the control alarm device comprises a processor, and a liquid crystal display module, a radio-frequency receiving module, a heater and an ultraviolet sterilizer which are connected with the processor; the power supply module comprises a hydroelectric generator and a battery; and each water quantity detection module comprises a mechanical water meter and a dry reed pipe. The invention implements water quantity detection and electronic display on the basis of the original mechanical water meter, implements centralized management on a plurality of water meters, has the functions of self power generation and alarming, implements the functions of meter reading and water quantity recharging in combination with the radio-frequency technique, has the functions of water heating and disinfection, and is convenient for people to use.

Description

Technical field: [0001] The invention relates to a water metering device, in particular to a self-generating intelligent water meter based on radio frequency technology. Background technique: [0002] With the rapid development of our country's economy, the shortage of fresh water resources in our country is becoming more and more serious, which has gradually become the "bottleneck" of my country's sustainable development. Statistics from relevant departments show that my country's per capita water resources are only 2,200 cubic meters, which is currently two-thirds of my country's Most large and medium-sized cities face water shortages. For example, Beijing has less than 300 cubic meters of water resources per capita, which is only 1 / 30 of the world's average level, similar to desert countries like Israel. Facing the serious situation of my country's water resources, how to reduce the actual water consumption of cities and towns to the minimum required by the society has bec...
