摘 要
本文扼要介绍了喷水织布机的工作原理及控制要求,并详细叙述了喷水织布
机控制系统控制电路及控制程序的设计过程,以及绘制电路原理图和 PCB 图的方
法及步骤。
喷水织布机的控制电路包括:主控电路、刹车电路、故障检测电路、整流电
路及强电电路等。其中主控电路以单片机 89C51 为控制核心,主要控制主电机的
正反转、正反点动,两个风机的启停;刹车电路控制织布机刹车装置的刹车动作
和高、低刹车电压的转换;故障检测电路用以检测断纬、左右捻边纱断纱、电机
过热、卷布筒张力过大等故障;强电电路用于实现电机正反转、三角形和星形的
转换等;整流电路为控制系统提供直流电源。
本控制系统的控制程序分为主程序和中断程序。主程序主要用于一些实时性
要求不高的信号的输入/输出和工作状态管理。中断程序用于处理一些实时性较
高的信号的处理。
本控制系统是一以单片机为控制核心的织布机控制系统。它比纯硬件控制系
统柔性高、更可靠,比 PLC 控制系统开发成本更低。经进一步的研究和开发,在
喷水织布机上具有良好的应用前景。

ABSTRACT
According to the principle and control requirement of the water jet loom, the
detailed design of the control system electric circuit, the control program for the water
jet loom, include the electric circuit diagram and PCB diagram, is introduced in this
paper.
The control of the water jet loom is composed of main control circuit, brake circuit,
malfunction examination circuit, commutate electric circuit and amplifier circuit. An
89C51 micro controller was taken as the control unit of the main control circuit to
realize the clockwise/anti-clockwise rotation, step movement of the main motor and
on/off of the two cooling fans. Brake electric circuit controls the braking movement of
the loom and the conversion of brake voltage. Malfunction examination electric circuit
is used to examine the break of the thread, overheating of the motor, the abnormal
tension and so on. The power circuit is used to realize the motor’s rotation, on/off
control and so on. Commutate electric circuits provide the direct current electricity for
the control system.
The control programs of the control system were classified as main programs and
interruption service programs. Main programs are mainly used for input or output of the
low real-time signal and the management of the work state. The interruption service
programs are used to deal with some higher real-time signal.
Because of its MCS-51 control unit, the loom control system developed in this paper
has a higher flexibility and reliability than that of the hardware control. At the same
time, the developing cost is much more lower than that of PLC. With further work, it
has good application foreground in water jet loom.
Key words:Water jet loom; Control electric circuit; Hardware; Software
