NB-IOT smart water meter with narrow-band internet of things

Abstract

The invention discloses an NB-IOT smart water meter with narrow-band internet of things. A first cavity and a second cavity are formed in a water meter body, wherein the first cavity is communicated with a water inlet, and the second cavity is communicated with a water outlet; a pressure sensor, a flowmeter and an overflow valve are arranged at the water outlet; a control module is connected withthe pressure sensor, the flowmeter and an NB-IOT wireless transmission module separately and used for transmitting pressure information measured by the pressure sensor and water flow information measured by the flowmeter to the NB-IOT wireless transmission module, the NB-IOT wireless transmission module sends the water pressure information and the water flow information to a terminal; a power supply module and a control valve are arranged in the first cavity and connected with the control module, the power supply module is used for supplying power for the control module, and the control moduleis used for controlling the opening-closing size of a valve port of the control valve. According to the NB-IOT smart water meter with the narrow-band internet of things, the NB-IOT wireless transmission module is adopted to send the water flow information and the water pressure information to the terminal, wireless meter reading is achieved, the labor cost is saved, and meanwhile data statistic errors caused by artificial meter reading are reduced.

Description

technical field [0001] The invention relates to the technical field of tap water meters, in particular to an NB-IOT narrowband Internet of Things smart water meter. Background technique [0002] In modern society, both industrial and civil uses consume a lot of water, so water supply companies need to collect water consumption data from users to calculate water consumption and costs. Most of the water meters in the prior art are mechanical water meters, which require manual meter reading, which is time-consuming and laborious, with low meter reading efficiency, high error rate, unstable water pressure and single function, which cannot meet the needs of intelligent society progress. Contents of the invention [0003] The main purpose of the present invention is to provide a NB-IOT narrow-band Internet of Things smart water meter, which aims to solve the problem that the water meter in the prior art requires manual meter reading, which is time-consuming and laborious, with l...
