Flow-saving air quality detection method and device

Abstract

The invention discloses a flow-saving air quality detection method and device with an aim to overcome the shortcomings existing in an existing air quality data reporting method. The method includes: comparing collected data with data collected last time in sequence, and calculating the difference between current measured data and the data measured last time as long as one of the data changes significantly; comparing with a set threshold value; if the air quality fluctuates greatly, recording and reporting the latest measured data to a server and waiting for the next round of measurement; utilizing software logic to judge whether the data collected by an air quality detection sensor are necessary to report or not to save unnecessary flow. More specifically, after sensor data are analyzed through a single-chip computer, whether or not to report the significantly changed data to the backend server is decided according to the set pattern.

Description

technical field [0001] The present disclosure relates to the field of Internet of Things monitoring, and in particular to an air quality detection method and device that saves traffic. Background technique [0002] Today, with the explosive growth of IoT products, almost all devices must be considered connected to the Internet. Some of the existing air quality detectors have the function of connecting to the Internet. Such devices generally need to transmit data to the background server to realize the "Internet of Things". The data transmission mode of the device is generally divided into two types, one is that the device periodically uploads data to the background server, and the other is that the background server periodically calls the data of the device. From the actual use situation, the air quality is a constant value for a relatively long period of time, and generally there will not be too much fluctuation in the value. Therefore, the above two data transmission meth...

Problems solved by technology

[0003] This disclosure provides an air quality detection method and device that saves flow. In order to solve the defects of the existing air quality data reporting method, the collected data is firstly compared with the last collected data one by one. As long as one of the data has obvious Changes (calculate the difference between the current measurement data and the last measurement data, and then compare with the set threshold), it is considered that the air quality fluctuates greatly, so the latest measurement data will be recorded and reported to the server, and then wait for the next round Use software logic to judge whether it is necessary to report the data collected by the air quality detection sensor, thereby saving unnecessary traffic
