【摘要】：针对传统经编机多板卡架构的电子贾卡控制系统存在的可靠性低、维护困难等问题,设计了一种面向工程应用、高度集成的新型嵌入式电子贾卡导纱针块(embedded electronic jacquard guide bar,EEJGB)。基于EEJGB,提出了一种兼顾通信可靠性和容错性的分布式混合异构串行通信架构,并对该通信架构进行了实时性分析。同时,为获取EEJGB的地址,提出了一种动态分配机制。为了验证该通信方法的有效性和可行性,以Modbus协议下的具体通信方法实例进行试验分析。分析结果表明:所提出的混合异构串行通信架构实时性高,在保证花型文件可靠传输的同时,极大地便利了EEJGB的故障定位、快速检修和分布式扩展,研究结果能够为新一代集成电子贾卡控制系统的设计提供有效的参考。
[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.
