摘要
针对喷气织机的电控系统对控制网络有较高的实时性要求,通过分析喷气织机电控系统的工作原理和国内外发展现状,提出由主控系统、电子送经/卷取控制系统、人机界面所构成的分布式控制系统,根据不同的功能需求独立设计相应的子系统,采用不同的CPU,并通过CAN总线实现CPU间数据通讯。实验仿真结果表明,该系统可以达到车速1 500 r/min、旋转角度9°/ms、织机角度的控制精度±2°的设计要求。
Aiming that the electronic control system of air-jet loom has high real-time request on control network, a new type of dis- tributed control system of air-jet loom was designed, which includes main control system, electronic let-off and take-up system and GUI system, by analyzing main theory and development around world of air-jet loom. Those sub-systems were designed independ- ently for their different functions. Each system has been controlled by special microcomputer, and they are communicated by CAN bus. Simulation program was designed to fit for the requirement of electronic control system, which is 1 500 r/min, 9°/ms, preci- sion is ±2°. The test result of timing sequence of weft insertion system shows that the main control system is feasible.
