Description
Technical Field
The invention relates to the technical field of production monitoring, in particular to a method and a system for monitoring production environment of non-woven fabric products.
Background
The technical field of production monitoring is a key component of industrial automation and intelligent manufacturing. The field of production monitoring technology relates to the use of various automated tools and techniques to monitor, control and optimize a production process. The aim in this field is to improve the production efficiency, to ensure the quality of the product, to reduce the costs and to ensure the safety of the working environment. Production monitoring techniques typically include real-time data collection, process monitoring, fault diagnosis, resource allocation, and scheduling optimization. In such specific applications of nonwoven production, quality control of raw materials, operating efficiency of production lines, maintenance of environmental parameters (e.g. temperature, humidity), and quality inspection of finished products are involved.
The method for monitoring the production environment of the non-woven fabric product is a technical method which is specially used for monitoring and managing the production process of the non-woven fabric product. The purpose of this method is to ensure the quality and efficiency of the nonwoven fabric during production, while reducing production costs and waste. By monitoring the production environment, problems in the production process, such as equipment failure or raw material defects, can be found and solved in time, so that the consistency and quality of the final product are ensured. In addition, the monitoring method is also beneficial to improving the safety of the working environment and preventing accidents. In order to achieve the purpose of monitoring the production environment of nonwoven fabric products, various means are generally adopted. This includes the installation of various types of sensors to monitor in real time critical parameters on the production line such as temperature, pressure, humidity and machine operating conditions. The data acquisition system will collect this data in real time, and predict equipment failure and production anomalies through advanced data analysis methods (e.g., machine learning algorithms). In addition, the monitoring system can be integrated into production management software to realize optimal allocation of resources and automatic adjustment of production flow.
The traditional monitoring method for the production environment of the non-woven fabric product has various defects. These methods often lack a fine division of the production links, resulting in generalized and inaccurate monitoring strategies. In terms of data processing, real-time analysis and processing often cannot be achieved, and therefore production efficiency and response speed are affected. Furthermore, conventional approaches suffer from deficiencies in the application of advanced data analysis and risk assessment tools, which make it difficult to effectively predict and address potential environmental risks. The lack of an effective preventive maintenance strategy is also an important drawback, often resulting in measures being taken after the problem has occurred. Moreover, the traditional method is relatively fixed and passive in terms of production environment adjustment, lacks dynamic adjustment capability based on real-time data, and limits optimization and environmental protection performance of production.
