Embedded remote PLC data collection and early warning system

Abstract

Provided in the invention is an embedded remote PLC data collection and early warning system comprising an information collection subsystem for collecting information of operating parameters and operating statuses of all PLC devices, a network communication subsystem for carrying out data transmission, instruction communication, and user authority information matching, and a system monitoring subsystem for controlling and managing all PLC devices and being responsible for remote monitoring of the operating status of the entire plant. The information acquisition subsystem includes a data acquisition module, a remote control module, and a collection information network middleware module. The network communication subsystem includes a permission management module and a data and control information transmission module. The network monitoring subsystem consists of monitoring center network middleware, a data visualization module and a user monitoring and management module. Therefore, the real-time data information of the PLC devices in the factory can be collected effectively and thus remote controlling is performed; and data analysis is carried out on the real-time data information topredict whether the PLC devices have faults.

Description

technical field [0001] The invention belongs to the field of industrial automation, and in particular relates to the field of realizing remote data collection and early warning functions of PLC through an embedded industrial control board. Background technique [0002] In the industrial automation industry, the application scenarios of data acquisition mainly occur between the upper computer system and the logic storage controller PLC on the workshop site. There are many contents of data acquisition, such as equipment operation status information, production quality, equipment operation parameter data, etc. In traditional applications, data acquisition is unilaterally read relevant data from the PLC by the host computer system or some configuration software, but cannot issue instructions. Moreover, there are different brands and models of PLCs in the factory, and the data message formats of different models of PLCs are different, which will increase the difficulty of collect...
