With the development of science and technology, intelligent manufacturing technology has gradually been applied to the printing and dyeing industry, improving production efficiency and product quality through automated equipment and advanced monitoring methods.
[0003] Currently, the monitoring of printing and dyeing production lines mainly relies on a single visual monitoring or auditory monitoring method. Visual monitoring uses cameras and image processing technology to monitor the color and pattern of fabrics, and detects problems such as color difference and uneven printing and dyeing; auditory monitoring uses microphones and sound analysis technology to listen to the sound of equipment operation and detect equipment failures and abnormalities. However, a single mode of monitoring has certain limitations and cannot fully and accurately reflect problems in the production process. Summary of the invention

[0069] Compared with the prior art, the present invention has the following beneficial effects:
[0070] 1. Comprehensive monitoring of the printing and dyeing production process is achieved by combining visual and auditory monitoring methods. Visual monitoring can accurately detect the color, pattern and surface quality of the fabric, and auditory monitoring can promptly detect abnormal sound signals during equipment operation. This dual-mode monitoring makes up for the shortcomings of single-mode monitoring, provides more comprehensive and accurate monitoring information, and improves the accuracy of fault detection and quality control.
[0071] 2. Through data fusion technology, visual data and auditory data are processed comprehensively to generate a more accurate comprehensive evaluation report. The multi-sensor data fusion algorithm improves the reliability and accuracy of monitoring information and reduces the errors and omissions that may occur in a single sensor.
[0072] 3. Using machine learning algorithms and big data analysis technology, the operating status of equipment can be monitored and analyzed in real time, and equipment failures can be predicted in advance. By establishing an equipment health model, the equipment operating status can be evaluated in real time, potential failures can be discovered in time, and early warnings can be issued. This real-time fault prediction capability significantly improves the reliability of the production line and reduces downtime and maintenance costs caused by equipment failures.
[0073] 4. Combined with visual and auditory data for comprehensive analysis, through pattern recognition and feature extraction technology, it can accurately locate and diagnose equipment failures. The network's efficient performance in image target detection and recognition enables visual monitoring to quickly identify fabric surface defects and equipment anomalies. Accurate fault diagnosis capabilities improve maintenance efficiency, reduce production losses, and ensure the stable operation of the production line.
[0074] 5. The control unit automatically adjusts parameters such as temperature, pressure, dye concentration and speed during the printing and dyeing process through a closed-loop control system based on real-time monitoring data and comprehensive evaluation reports. The closed-loop control system can optimize production parameters in real time to ensure the best production results. Real-time control and optimization improve the automation and intelligence level of the production process, reduce human intervention and misoperation, and improve production efficiency and product quality.
[0075] 6. Through real-time monitoring and data analysis of the printing and dyeing process, the production parameters can be adjusted intelligently to ensure the consistency and stability of printing and dyeing quality. The automatic adjustment system can dynamically adjust the production parameters according to the different characteristics of the fabric and production requirements to meet different production needs. Intelligent adjustment of production parameters effectively reduces the uncertainties in the production process and improves the consistency and quality pass rate of products.
[0076] 7. The safety monitoring module combines visual and auditory monitoring methods to monitor the workshop environment and equipment operating status in real time, and promptly identify and deal with potential safety hazards. By detecting abnormal visual and auditory signals, it can effectively prevent accidents such as fires, leaks, and unsafe operations by personnel. Comprehensive safety monitoring improves the safety of the production process and ensures the safety of operators and equipment.
[0077] 8. The safety monitoring module can send out alarm signals in time when abnormal situations are detected, including local sound and light alarms and remote alarms. The alarm system can quickly notify on-site personnel and management personnel to take appropriate safety measures to prevent accidents from occurring and spreading. Timely alarm and response mechanisms improve the efficiency of handling safety incidents and reduce accident losses and personal injuries.
[0078] 9. By improving production efficiency, reducing equipment failures and downtime, and optimizing the production process, production costs can be significantly reduced. The improvement of automation and intelligence levels reduces dependence on manual operations and reduces labor costs. By improving product quality and consistency, the defective rate and rework costs are reduced, further reducing production costs.
[0079] 10. The efficient, accurate and safe production management system has improved the quality and production efficiency of printing and dyeing products, bringing higher economic benefits to the enterprise. Through the application of intelligent manufacturing technology, the innovation ability and market competitiveness of the enterprise have been improved. High-quality and efficient production capacity enables enterprises to better meet market demand, win more customers and orders, and enhance market competitiveness. BRIEF DESCRIPTION OF THE DRAWINGS
