[Abstract]:Aiming at the problems of low reliability and difficult maintenance in the electronic card control system of traditional warp knitting machine, a new type of embedded electronic Jacquard guide needle block (embedded electronic jacquard guide bar,EEJGB) for engineering application and high integration is designed. This paper presents a distributed hybrid heterogeneous serial communication architecture based on EEJGB, which takes both reliability and fault tolerance into account, and analyzes the real-time performance of the architecture. At the same time, in order to obtain the address of EEJGB, a dynamic allocation mechanism is proposed. In order to verify the effectiveness and feasibility of the communication method, a practical example of communication method under Modbus protocol is used to test and analyze. The analysis results show that the proposed hybrid heterogeneous serial communication architecture has high real-time performance, which ensures the reliable transmission of pattern files and greatly facilitates the fault location, rapid overhaul and distributed extension of EEJGB. The results can provide an effective reference for the design of a new generation of integrated electronic card control system.
