Data processing method and edge computing data box

Abstract

The embodiment of the invention discloses a data processing method and an edge computing data box which are used for processing original data acquired from a PLC in the edge computing data box throughDLL files compiled by the edge computing data box. The data processing capacity and the data processing efficiency are improved, and the flexibility and practicability of data processing are improved. The method comprises the steps that the edge computing data box acquires the original data from an IO interface of the PLC, wherein the original data is data which is input into the PLC from external equipment and is not processed by the PLC; the edge computing data box judges whether the dynamic link library (DLL) files exist in the edge computing data box or not, wherein the DLL files are compiled by a self-defined logic control program according to a high-level language, and the self-defined logic control program is compiled according to the high-level language; if yes, the edge computingdata box calls the DLL files to process the original data to obtain target data; the edge computing data box sends the target data to the PLC, so that the PLC controls the external equipment throughthe target data.

Description

technical field [0001] This application relates to the field of computer technology, in particular to a data processing method and an edge computing data box. Background technique [0002] Programmable logic controller (programmable logic congtroller, PLC) is a data operation electronic system specially designed for application in industrial environments. It uses a programmable memory to perform logic operations and sequence control in its internal storage , Timing, counting and arithmetic operation instructions, through digital or analog input and output to control various types of mechanical equipment or production processes. Edge computing refers to an open platform that integrates network, computing, storage, and application core capabilities on the side close to the source of objects or data to provide the nearest end services, between physical entities and industrial connections, or in physical entities. At the top, before the data is integrated to the cloud or data c...

Problems solved by technology

[0004] However, within the PLC, only simple processing can be performed on the data obtained from external devices (for example: obtain temperature information, turn on the alarm light when the temperature is greater than 50 degrees), the logic control that PLC can handle is similar to the condition Simple logic of the control statement (ie if-else) type, but cannot handle complex business control logic (for example: when the temperature is greater than 50 degrees, obtain product process information, and decide whether to cool down, warn, or notify based on the product process information Relevant processing personnel), and in order to make the updated logic control program take effect, it is necessary to restart the PLC after each update, which affects the production of equipment, reduces production capacity and increases production costs
