Novel energy-saving ultrasonic heat meter based on IOT technology

Abstract

The present invention discloses a novel energy-saving ultrasonic heat meter based on the IOT technology. The novel energy-saving ultrasonic heat meter comprises an ultrasonic heat meter, a control valves, a data acquisition device and a heat use metering and temperature controlling device. According to the novel energy-saving ultrasonic heat meter based on the IOT technology, an ultrasonic sensor is installed on a water pipe, the flow speed of water is measured through measuring the change of sound wave transmission speed in the water, thus the flow speed is multiplied by a pipeline cross section to obtain the flow of the measured water, and the accuracy of measurement is improved. At the same time, a reflection mirror is fixed in the pipeline central axis with a fastest flow speed through a bracket, due to no mechanical structure, the wear resistance effect is good, and due to the water flow impact and inclined reflecting surfaces, the relative influence of sediment is reduced. At the same time, a transducer test interface is parallel to a pipeline, no bubble and suspended solids accumulate in the operation process of the water, so the signal attenuation is small, and thereby the accuracy of the measurement is further improved.

Description

technical field [0001] The invention relates to the field of meters, in particular to a novel energy-saving ultrasonic heat meter based on Internet of Things technology. Background technique [0002] With the improvement of people's living standards, users have more and more urgent requirements for personalized heating and improved comfort. In the traditional heating system, users are in a passive state, and the indoor temperature is adjusted by the heating unit. This single adjustment cannot meet the different needs of users. The implementation of the Internet of Things system for heating household metering can not only meet the needs of users, use indoor temperature control devices (such as hot water electric control valves) to independently adjust the required room temperature within a certain temperature range, but also meet the urgent needs of heating companies. management needs. [0003] The traditional heat supply users who charge by area have to pay the full fee no...

Problems solved by technology

Since there is no unified national or industry standard, the systems of various companies cannot be unified with each other, which makes the meter reading systems of various cities or real estates diverse, and maintenance is difficult and complicated; especially the remote meter reading systems currently installed and used are mostly sub-lines The task of engineering installation and wiring is heavy, and there are hidden dangers of short circuit and disconnection in long-distance lines. The intricate lines also make system debugging and system maintenance difficult.

Thereby existing heat meter can not really satisfy people's demand
