Embedded industrial gateway acquisition system of internet of things and operation mode thereof

Abstract

The invention discloses an operation mode of an embedded industrial gateway acquisition system of internet of things, wherein the operation mode of the embedded industrial gateway acquisition system of internet of things comprises the steps of data collection, read-write operation and heat replacement driving. The invention further discloses an embedded industrial gateway acquisition system of internet of things, wherein the system comprises sensors and functional instruments for collecting physical data and a data channel, and also comprises an embedded Linux system, a NodeJS module and a heat replacement drive; the drive generates an request online and initiates the request to a heat replacement driving part; then, the request is submitted to the channel adaptation; and the embedded industrial gateway acquisition system of internet of things dynamically switches channels in the operation stage through the channel adaptation. The embedded industrial gateway acquisition system of internet of things adopts a currently popular NodeJS platform to develop, and the module is supported to be dynamically loaded and replaced, thereby supporting the functions of drive on-line writing, testand dynamic replacement to the largest extent, and converting the collected data into the internet of things protocol form (such as CoAp, MQTT and the like. ) to publish and finally achieving the function that the industrial data is seamlessly connected to a cloud management platform.

Description

technical field [0001] The invention relates to the field of industrial control systems based on the Internet of Things, in particular to an embedded industrial Internet of Things gateway acquisition system and its operation mode. Background technique [0002] Data Acquisition (DAQ), refers to from sensor Automatically collect non-electricity or electric quantity signals from analog and digital units under test, such as other equipment under test, and send them to PC analysis and processing. data collection system is combined based on computer Or other dedicated test platform measurement software and hardware products to achieve flexible, user-defined measuring system . exist the Internet Today, with the rapid development of the industry, data collection has been widely used in the Internet and distributed fields, and important changes have taken place in the field of data collection. First, intelligence in distributed control applications data collection system...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional industrial data acquisition protocols are complicated and complex, and it is difficult to adapt to the business requirements of Internet of Things data access, and the traditional embedded acquisition gateways are often developed in C / C++ language. Because of the static compilation feature, the acquisition driver is often difficult to dynamically update, replace
