摘要:

棉纺织厂根据工艺、品种和批量对筒子纱进行烘干,传统方法是在充满暖气的烘房完成。这样的方法具有控制不灵活和浪费等缺陷。在小环境中采用单片机完成定时、定温的烘干控制较好解决了传统方法的缺陷。系统以单片机为核心配以控制简单、运行可靠的双向二极管、双向可控硅、固态继电器作为驱动部件,并采用新型的接近开关和温度传感器作为系统的检测部件,检测精度高,为系统提供准确的反馈信号。人机对话采用简易的小键盘、单色数码管和蜂鸣器让系统的操作方便、人性化。

Abstract:

The cheeses are dried according to the weaving technique, type of yarn and batch number in the cotton textile factory. The conventional method of drying in warm house is less flexible and costly. However, if the cheese is dried in a small space, and the temperature and time of drying is controlled by single chip machines, those mentioned drawbacks of conventional methods can be overcome. Thus, the paper proposes a drying system comprising a microcomputer at the center and the easy and reliable bi-directional diodes, bi-directional SCR, solid relay as a driver components. A new type of proximity switches and temperature sensors are also included as testing components which are highly precise in testing and can give accurate feedback signal to the system. In addition, the use of simple keyboard, monochrome digital tub and buzzer in the interaction of human and machine makes the system easy to operate and user-friendly.
