A real-time reporting method for sensor data self-adaptive acquisition

Abstract

The invention discloses a real-time reporting method for self-adaptive collection of sensor data, comprising: sampling thread initialization, judging whether the number of sensors connected to the Internet of Things system is less than or equal to a preset number threshold; if so, judging whether the number of sensors is 0 ; If it is not 0, initialize the sampling sleep time according to the number of sensors, and the sampling sleep time is the time interval between collecting the sensor values ​​twice; the sampling thread loops through the sensor values ​​with the sampling sleep time as the interval to obtain the collection value; when the preset reporting period arrives, the periodic reporting thread preprocesses two or more collection values, calculates the collection average value, encodes the collection average value, and reports it to the server. Compared with the prior art, the present invention can be used to realize data collection in different Internet of Things application scenarios, and has the characteristics of adaptability, real-time performance and high stability.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method for self-adaptive collection and real-time reporting of sensor data. Background technique [0002] During the data collection process of the Internet of Things system, if the gateway collects sensors for a certain number of times in a reporting period, when the number of collections is small, for example, when the sensor is collected once in a reporting period, as the number of sensors increases, there may be If some sensors are not collected within a reporting cycle, the data received by the server cannot accurately reflect the status of all sensors connected to the current IoT system, so it is ensured that the gateway collects data from all connected sensor devices. Data integrity is essential. Furthermore, if the gateway collects the sensor only once in a reporting cycle, the accuracy of the data received by the server will not be high enough due to the occasion...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a real-time reporting method for self-adaptive collection of sensor data to solve factors such as time delay and unstable reporting period when the existing Internet of Things gateway reports data, which leads to irregular data stored on the server side, such as irregular periods. Stability, lack of collected values ​​of some sensors, serious data glitches, etc., affect the later data processing and data analysis, resulting in low working efficiency of the IoT gateway
