Hydraulic pressure gauge pressure data transmission method based on NB-IOT

Abstract

The invention discloses a hydraulic pressure gauge pressure data transmission method based on NB-IOT, and the method comprises the steps: a water pressure data collection step: collecting real-time water pressure data, and sending the real-time water pressure data to a water pressure monitoring end; a data straight line segment preliminary fitting step: the water pressure monitoring end carries out operation fitting on the real-time water pressure data through a judgment program to obtain a data straight line segment and judges the data types of the real-time water pressure data; a step of determining real-time water pressure data by using the fitting data straight line segment: continuing to operate the acquired real-time water pressure data to fit the data straight line segment so as todetermine the data type of the real-time water pressure data; and a real-time water pressure data storage and uploading step: storing and uploading the real-time water pressure data based on NB-. TheIOT communication module classifies and uploads the real-time water pressure data; according to the method, integrity and real-time performance of transmitted real-time pressure data can be met, and NB-can be achieved. The low-power-consumption low-frequency data transmission of the IOT communication module not only reduces the cost of battery maintenance and replacement, but also reduces the difficulty of server-side data analysis.

Description

technical field [0001] The invention relates to a method for transmitting pressure data of a water pressure gauge, in particular to a method for transmitting pressure data of a water pressure gauge based on NB-IOT with low power consumption. Background technique [0002] For the water supply system, the collection of water pressure signals provides an important basis for judging whether the stations of the water supply system are operating normally, whether there are leakages in the pipe network, and is a direct indicator of the pressure of the pipe network. A very important part. [0003] At present, it is difficult to realize wired power supply in many water pressure data collection scenarios in the water supply industry. Some sensors are installed in relatively remote environments, and wired power wiring is difficult. Therefore, wireless power supply is required and power consumption of equipment operation needs to be reduced. [0004] NB-IOT (cellular narrowband Interne...

Problems solved by technology

However, because its own low power consumption is achieved by reducing the transmission frequency, and for the monitoring and analysis of pressure data, the data often needs to have a certain real-time performance. Therefore, most manufacturers who use NB-IOT technology to realize low-power pressure gauges, In order to make the pressure data meet the real-time requirements, the transmission frequency of the pressure data is increased, which leads to an increase in the power consumption of the NB-IOT transmission device, and the service life of the battery is reduced accordingly.
