摘　　要：针对结构复杂、多板卡级联形式的传统经编机电子贾卡控制系统存在可靠性低、占用物理空间大、安装与检修困难等问题,设计了一种将微控制器、花型数据存储器、贾卡驱动电路、升压电路以及通信接口功能模块高度集成在贾卡导纱针块内部的嵌入式电子贾卡控制系统,电子贾卡导纱针块采用了全双工、低功耗的MAX488实现串行菊花链式通信模式。在系统分析压电陶瓷贾卡提花工作原理和特点的基础上,给出了嵌入式电子贾卡控制系统的系统架构、硬件电路的设计和实现方法。测试结果表明,该系统无需额外接入高压电源就能够独立工作,性能稳定,可靠性高,功能完备,抗干扰能力强。Aiming at the low reliability and maintenance difficulties problem of conventional warp knitting machine electronic jacquard control system with complex multi-card structure, this paper designed an embedded electronic jacquard control system,in which the microcontroller,pattern data memory,jacquard drive circuit,boost circuit and communication interfaces were integrated inside the piezo jacquard guide bar. The system with a distributed control architecture is called as the embedded electronic jacquard guide bar. The embedded electronic jacquard guide bar mounted in a warp knitting machine adopts two MAX488 chips with full-duplex and low-power to implement serial daisy chain communication mode. Based on the analysis of the principle and characteristics of piezoceramic jacquard patterning,the paper also provided the design and implementation methods of the architecture and hardware circuit of embedded electronic jacquard control system. Test results show that the designed system can work independently without access to high voltage power supply, and which stable performance,high reliability,full function and strong interference resistance.
