Embodiment

[0044] Such as figure 1 As shown, the edge computing-based industrial sensor signal collection method shown in the overall schematic diagram of the implementation of the present invention mainly adopts a "divide and conquer" method to divide it into three steps, namely local information collection, regional information collection and global information collection.

[0045] Local information collection process such as figure 2 As shown, the sensor signal collector receives information collected by multiple sensors, and analyzes and processes different types of information from different sources. The processing method is as follows:

[0046] 1. For digital signals, the sensor signal collector will record the change of its high / low level signal and the time of occurrence. The storage format of its data is as attached image 3 As shown, where "D" means that the information is a digital signal, "Num(i)" is the i-th sensor, and "0 / 1" is the high and low level signal of the sensor ...

Abstract

The invention discloses an industrial sensor signal collector based on edge computing and a collection method. The information collection in the entire industrial scene is divided by equipment and functions thereof into local information collection, regional information collection and global information collection. The local information collection is that a sensor signal collector is responsible for collecting sensor information in a region where the sensor signal collector is located and carries out format conversion, alarm output and other processing according to the source and type of the collected information. The regional information collection is that an edge computing platform collects sensor information of local information collection nodes managed thereby, carries out compression,temporary storage, uploading and other processing on the acquired conventional information, and carries out real-time response processing on fault information. The global information collection is achieved in that a cloud computing platform decompresses and stores the uploaded information of the edge computing platform so that the cloud computing platform can perform a global analysis on the industrial production data.

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to an edge computing-based industrial sensor signal collector and a collection method. Background technique [0002] With the rapid development of cyber-physical fusion systems and Internet of Things technology, data has become an important factor affecting industrial transformation and upgrading. In the current industrial control system, the detected data is only used to trigger a response to an event during the control process. In addition, the existing control facilities in industrial applications do not have the ability to predict and analyze the detected data, Mass storage and other processing mechanisms. Therefore, it is necessary to combine corresponding sensor signal acquisition equipment and network information technology to realize large-scale acquisition, storage, analysis and other processing of industrial production data. [0003] The industrial ...
