Industrial equipment intelligent monitoring video acquisition method based on PLC

Abstract

The invention is applicable to the field of computers, and provides a PLC-based intelligent monitoring video acquisition method for industrial equipment, which comprises the following steps of: monitoring communication signals of equipment connected with a PLC; through a data acquisition module A, state data of each piece of equipment is obtained at regular time and stored in a PLC database; then event occurrence time and equipment information corresponding to the communication signals are obtained through a data acquisition module B, data obtained at different times are compared bit by bit, useless data are filtered out, and useful data are stored in a database; through a data acquisition module C, regularly extracting data in the database, and querying a corresponding video recording file stored in the monitoring system according to the data in the database and a flag structure state generated in a data storage process; and carrying out video recording interception and local storage operation. The data cleaning function is realized, and valuable video images are screened out through the logic of the method, so that the intelligent recording function of industrial equipment is realized.

Description

technical field [0001] The invention belongs to the field of computers, and in particular relates to a PLC-based intelligent monitoring and video recording acquisition method for industrial equipment. Background technique [0002] At present, the PLC (programmable logic controller)-based equipment on the market basically displays the abnormal information on the HMI (human-machine interface) of the equipment in descriptive content, but the actual state and action of the equipment in the running state cannot be captured, and The functions that traditional monitoring can provide are only recording and uninterrupted recording of images according to the image capture algorithm, and cannot be associated with device data. Contents of the invention [0003] An embodiment of the present invention provides a PLC-based method for collecting intelligent monitoring and video recording of industrial equipment, aiming to solve the problems raised in the background technology. [0004] T...
