A method for realizing edge control in an Internet of Things gateway

Abstract

The invention provides a method for realizing edge control in an Internet of Things gateway. The method is provided with a system architecture composed of a cloud server and an Internet of Things gateway. The cloud server is used for configuration management, state monitoring and remote control of the Internet of Things gateway, the controlled equipment and the sensor; the Internet of Things gateway is used for realizing protocol conversion, data analysis and edge control functions in a control process, the Internet of Things gateway comprises a controller part and a collector part, and the controller part comprises a control configurator, a control scheduler, an input device, a control machine and an actuator. According to the method, a parameterized control algorithm is built in an Internet of Things gateway; The control logic is placed in the Internet of Things gateway close to the controlled device, the specific device is dynamically bound through the configuration means, differentcontrol instructions are called, and therefore universal device control on the edge side is achieved on the basis of the Internet of Things gateway, real-time control and remote control over the device can be facilitated through the method, expandability is high, and remote control is convenient.

Description

technical field [0001] The present invention relates to the control technology of Internet of Things equipment, in particular to a method for placing the control logic in the IoT gateway close to the controlled equipment, and realizing the control of general equipment on the edge side on the basis of the IoT gateway. The method can facilitate Real-time control and remote control of equipment, large scalability and convenient remote control. Background technique [0002] The Industrial Internet of Things aims to elevate the traditional industry to a new stage of networking and intelligence. Its application has the characteristics of real-time and openness. Its principle is to connect different equipment and machines to the Internet and acquire Equipment working conditions or environmental information, analysis and optimization of equipment efficiency and energy consumption, equipment management and feedback control; how to conveniently and effectively realize remote control o...

AI Technical Summary

Problems solved by technology

[0003] 1. The equipment control algorithm is solidified, and the scalability is poor. The control algorithm is written in advance for specific equipment, and the control algorithm is solidified. Once the control logic of the equipment changes or new equipment is connected, the control program needs to be rewritten, so it is difficult to adapt to the Industrial Internet of Things dynamic application requirements;

[0004] 2. It is difficult to realize the remote collaborative control of multiple devices, and the compatibility is poor. Traditionally, a single device or multiple devices in a limited area are controlled by sending control commands from the upper computer. Usually, it is closed-loop control in a local area network. In the open environment of the Industrial Internet of Things , the equipment is discrete and dynamic (new types of equipment can be added at any time), how to remotely control equipment in the cloud for massive sensors and equipment is the current challenge;

[0005] 3. It is difficult to guarantee the continuity of remote control of equipment. At present, the remote control method of equipment in the industrial Internet of Things is that the cloud server sends equipment control instructions to the controller of the equipment, such as a single-chip controller or PLC or a control machine, to realize specific control. This control method has poor interactivity, and it is difficult to realize continuous remote control of the equipment
