Introduction

With the advent of the era of Industry 4.0, the entire sewing machinery industry in my country is transforming in the direction of automation and digitization.

Digital control will gradually replace manual labor and become the mainstream of the industry.

The digital control system of the sewing machine is the main component to realize the digital control of the sewing machine.

The digital control system controls the action of each unit of the sewing machine, so as to realize the automation of the sewing machine. At the same time, through the server and digital control Data exchange between systems can realize interconnection and data sharing between sewing machines. GB/T 24114 "Mechanical and electrical equipment "Preparation of Sewing Machinery Digital Control System" ensures the basic performance and safety performance of the sewing machinery digital control system, and solves the problem of sewing machinery interconnection.

The matching problem in the intercommunication process is proposed to be composed of four parts.

--- Part 1: General technical conditions. The purpose is to standardize the basic functions and performances common to all kinds of sewing machinery digital control systems Requirements and safety protection performance, environmental adaptation performance, electromagnetic compatibility performance, manufacturing quality, packaging and transportation requirements.

--- Part 2: Data dictionary. The purpose is to convert the static data, dynamic data and status of various sewing machinery and equipment in the process of processing.

Data, processing process and result data, alarm maintenance data, etc. are regulated in accordance with the requirements of GB/T 33863 "OPC Unified Architecture".

Fan, forming the basic data dictionary for the interconnection of sewing machinery.

--- Part 3: Data exchange. The purpose is to establish the data between the digital control system and the server on the basis of the second part Exchange protocol to realize freedom between management software such as MES, VMS, MDC, SCADA and sewing machinery digital control system data exchange. Establish sewing machinery equipment models and mapping requirements between models and protocols, and finally realize the interconnection of sewing machinery Interoperability and data sharing under the premise of security assurance.

--- Part 4: Test and acceptance. The purpose is to provide specifications for the experimental verification of the requirements of Parts 1 to 3.
