Intelligent remote-transmitting heat meter and working method thereof based on temperature difference and impeller complementary power generation technology

Abstract

The invention discloses an intelligent remote-transmitting heat meter based on a temperature difference and impeller complementary power generation technology and a working method of the intelligent remote-transmitting heat meter. The intelligent remote-transmitting heat meter is composed of a power supply system, an intelligent control system, a heat measurement system and a communication system, wherein the power supply system collects the dissipated heat energy and the fluid dynamic energy of a pipeline to support the working of the heat measurement system and the communication system, the intelligent control system controls the charge and discharge processes of lithium ion circuits of the power supply system and the switching of working modes of a gauge in different seasons, and the communication system transmits the flow data obtained by the heat measurement system to a user terminal. On the basis of the existing power supply system and the measurement system, since the power generation technology of a power supply system working medium and the temperature difference of the ambient temperature is combined with the power generation technology that a motor is driven by the impeller who is driven by fluid in the pipeline and a wireless remote-transmitting function is increased, the low cost and the energy-saving performance can meet the requirements of times.

Description

technical field [0001] The invention relates to an instrument for measuring the heat transferred by a flowing medium in a heating system, in particular to an intelligent remote heat transfer heat meter based on the complementary power generation technology of temperature difference and impeller. Background technique [0002] The household heat meter is mainly used to measure the central heating of the household heat meter heat network. It is a combination of measuring the temperature difference between the inlet and the outlet and measuring the flow rate of the medium, so as to measure the consumed heat and use it as charging data. [0003] Traditional heat meters usually use a built-in battery for power supply. Although the cost is low, the battery is fragile and requires maintenance. Because the power supply is not enough to support remote communication, people need to come to the door to read the meter, which makes management inconvenient. However, heat metering devices w...
