Distributed monitoring system and monitoring method

Abstract

The invention relates to the technical field of textile, in particular to a distributed monitoring system and monitoring method, and aims to design an online acquisition unit comprising a displacementsensor and a pressure sensor for a laminated fabric forming process, and monitor changes of fabric height and pressure in the fabric forming process through real-time sampling of the online acquisition unit. Weak current detection signals of all sensors are transmitted to a programmable controller in time by means of a bus communication mode; the programmable controller is used for carrying out centralized processing on the received signals, judging whether fabric forming is abnormal or not in combination with pressure applying trigger signals and set process parameters, and transmitting processed monitoring, abnormal states and the like to an upper computer; the upper computer stores the data into a fabric database, centralized online monitoring is achieved, the fabric production state is traced back, and a user can conveniently know laminated fabric forming information through man-machine interaction equipment. The system is simple in structure, the fabric quality is improved, and the product stability and the fabric data information integrity are ensured.

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 cloth or fiber layers are densely compacted under the action of external force and connected 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 used in aerospace and other fields, and is gradually used in aerospace, chemical, automotive, medical and other high-tech fields. [0003] In the process of forming laminated fabrics, applying pressure is an important process of fabric forming, and is an important factor affecting the contrast height of fabrics. At present, there is no effective means to monitor the pressure and contrast height of the fabric in the forming process of laminated f...

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
