MQTT-based data reporting method, device, computer equipment and storage medium

Abstract

The invention discloses an MQTT-based data reporting method, device, computer equipment and storage medium, with less resource occupation and high reporting efficiency. The MQTT-based data reporting method includes the following steps: (10) start the MQTT main link: through the MQTT main link, subscribe to the device control topic, receive and process the device control command; (20) report the device data: from the device to be reported Take out the device data from the data queue, select an idle link from the MQTT main link and MQTT slave link queue, and report the device data through the interface corresponding to the idle link; (30) dynamically adjust the slave link: according to the real-time monitoring gateway to report the device data Traffic range, increase or decrease the number of MQTT slave links used for device data reporting.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, in particular to a data reporting method, device, computer equipment and storage medium based on MQTT. Background technique [0002] In the field of IoT, reporting device data through the MQTT (Message Queuing Telemetry Transport) protocol has become a de facto standard. For example, the Amazon IoT platform supports the use of MQTT connection to report device data. [0003] Due to the massive support capability of the number of access devices, the current IoT platform device access concept is generally distributed access. Usually, one MQTT connection corresponds to one device. In this way, a single MQTT connection only reports the information of one device. At the same time, the IoT platform It also limits the reported traffic rate of a single connection, such as Amazon IoT. [0004] In actual use, for areas where devices are concentrated, it is unrealistic to allocate one MQTT co...

AI Technical Summary

Problems solved by technology

If you use a gateway to report thousands of devices, you need to create thousands of MQTT connections in the gateway, which will consume a lot of computing resources of the gateway

When the computing resources of the gateway are limited, it will not be able to support so many devices for reporting

In addition, even if the gateway supports it, the gateway side switches among thousands of connections, which is very inefficient

[0005] Another solution is to provide all devices with an MQTT connection for device reporting, but due to the limitation of the Internet of Things platform for a single MQTT connection traffic reporting rate, it is impossible to use a single MQTT to provide data reporting for a large number of devices at the same time

[0006] Therefore, the problem existing in the existing technology is: due to the limitation of the data reporting rate of the MQTT single-link device in the Internet of Things, when the number of connected devices is huge, it needs to occupy a large amount of gateway computing resources, and the efficiency of device data reporting is low.
