Abstract Aimed at the problems of low reliability and maintenance difficulties in the traditional warp knitting machine electronic jacquard control system with complex multi-card structure, a novel embedded electronic jacquard guide bar (EEJGB) characterized by highly integrated is designed. Based on EEJGB, a hybrid isomerism serial communication system was designed. Such system ensured real-time communication as well as reliability and fault tolerance of communication system, which was investigated using real-time analysis. Meanwhile, a new dynamic configuration method of EEJGB addresses was proposed.To prove the effectiveness and feasibility of the proposed communication scheme, a case of Modbus based on communication scheme was provided in detail. The analysis shows that the proposed hybrid isomerism communication architecture with high real-time performance can ensure the reliable delivery of pattern files and fault location, rapid maintenance and distributed expansion of EEJGB, which can offer some useful reference for the design of the new generation of integrated electronic jacquard control system.

经编机电子贾卡混合异构串行通信系统设计
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。
