A distributed monitoring system and monitoring method

Abstract

The invention relates to the field of textile technology, in particular to a collection and distribution monitoring system and a monitoring method. An online acquisition unit including a displacement sensor and a pressure sensor is designed for the forming process of a laminated fabric, and real-time sampling is used to monitor the fabric height, the Under the change of pressure, the weak current detection signals of all sensors are transmitted to the programmable controller in time by means of bus communication; the programmable controller performs centralized processing on the received signals, and combines the applied pressure trigger signal and the set process parameters to judge the fabric Whether there is any abnormality in the molding, and transmit the processed monitoring and abnormal status data to the upper computer; the upper computer stores the data in the fabric database, and realizes centralized online monitoring and traceability of the fabric production status, which is convenient for users to know the stacking through human-computer interaction equipment. Layer Fabric Forming Information. The system has a simple structure, improves fabric quality, and ensures product stability and fabric data information integrity.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a distributed monitoring system and a monitoring method. Background technique [0002] Laminated fabric refers to a three-dimensional fabric in which the cloth or fiber layer is densified and compacted under the action of external force, and the connection is established by Z-direction fibers. This type of fabric has a good overall structure and high fiber volume content, which solves the problem of large-size and high-thickness forming of three-dimensional fabrics in aerospace and other fields, and is gradually used in aerospace, chemical, automotive, medical and other high-tech fields. [0003] In the forming process of laminated fabrics, applying pressure is an important process in fabric forming and is an important factor affecting the contrast height of fabrics. At present, there is no effective means to effectively and centrally monitor the pressure and contrast height of...

Problems solved by technology

Although these documents all adopt the distributed control DCS structure, no research has been carried out on sensor design, database creation, etc. At the same time, the first paper focuses on on-site control and production line operation status monitoring, and the second paper focuses on canceling manual on-site observation to ensure safety. The third part focuses on the real-time control of the temperature of the liquid medicine tank, which is different from the starting point of improving the quality of laminated fabrics, ensuring product stability and fabric data integrity, so that the operating methods of these systems cannot be applied to the collection and distribution of laminated fabric forming processes monitor

[0005] In summary, there is no research and application of the distributed monitoring system in the forming of laminated fabrics. Therefore, the present invention proposes a distributed monitoring system and monitoring method that can realize automatic monitoring of process parameters in the forming process of laminated fabrics, and improve the quality of fabrics. Quality, guarantee product stability and fabric data information integrity, and then lay the foundation for realizing the informatization and intelligence of this kind of fabric industry
