Non-intrusive screen monitoring image-text dynamic recognition system and method

By using a non-intrusive screen monitoring and dynamic image recognition system, the system identifies the status of aging equipment through visual perception and intelligent decision-making modules. Combined with the control execution module, it achieves closed-loop control, solving the problems of false alarms and uncontrolled execution on the interface of aging equipment. This results in highly accurate and low-cost equipment status monitoring and control.

AI Technical Summary

Technical Problem

The data link between the human-machine interface and the underlying execution system of outdated industrial equipment is broken, resulting in the inability of the operation front end to provide real-time feedback on the equipment status, lack of proactive intervention capability, and risks of production loss of control and safety accidents.

Method used

A non-intrusive screen monitoring and image recognition system is adopted. The system captures images of the screen area through the visual perception module, performs feature matching in combination with the intelligent decision-making module, and outputs control signals through the control execution module to achieve equipment status monitoring and closed-loop control.

Benefits of technology

Without modifying the hardware or relying on the underlying interface, it achieves highly accurate and low-cost device status identification and control, solves the problems of false alarms and execution failure, and the device response latency is less than 200ms.

Abstract

The invention relates to the technical field of industrial equipment control, in particular to a non-intrusive screen monitoring image-text dynamic recognition system and method, the system comprises a region configuration module, a visual perception module, an intelligent decision module and a control execution module, and based on the system, the recognition method comprises the steps of determining a to-be-detected screen region in response to a configuration operation of a user; and identifying the preprocessed image through a screen self-capture technology running in a host operating system, outputting an instruction when an identification result is abnormal, and controlling the industrial equipment to start and stop. Equipment state information is obtained through a non-intrusive mode of a visual level, a non-intrusive relay series mechanism of a control level is adopted, and state monitoring and closed-loop control of an old industrial equipment man-machine interface can be achieved on the premise that hardware is not transformed and an internal communication protocol of the equipment is not accessed. The industrial problems of'interface false alarm 'and'out-of-control execution' are solved, and the method has the advantages of high compatibility, low cost and fast deployment.
