基于PLC的工业晾晒架系统
摘要：自动晾晒架能方便晾晒物的自动晾晒与回收。当晾晒的物品超过设定的重量时会实现报警功能。如遇刮风，大雨，大雾等天气或者室外温度过高，并且企业忙碌没人看管晾晒物时实现自动回收。与传统的半自动晾晒架相比，自动晾晒架拥有更便捷更方便的晾晒体验。现代社会随着科技与人们对高品质生活，企业工厂对高效率的追求，自动晾晒架必能成为日后市场的主力发展品。
本设计以西门子300PLC作为系统的控制与检测的核心。通过称重传感器来实现晾晒架重量检测，并且通过二极管及喇叭来实现超重报警。能实现晾晒物品的升降，并遇到大风，大雨，高温天气，通过风速传感器，湿度传感器，温度传感器进行检测。并且通过直流电机的带动，实现晾晒物的自动回收。毫无疑问，也可以通过手动来晾晒与回收。软件部分采用了不同功能分开控制设计，实现晾晒架状态功能的显示和自动运行。本设计简单实用，基本满足设计内容与要求。

Automatic drying rack system based on PLC
Abstract: Automatic drying and recycling automatic airer can facilitate drying. The alarm function is realized when the air dried object exceeds the set weight. In case of wind, heavy rain, heavy fog, weather or outdoor temperature is too high, and enterprises busy, no one to look after the drying, automatic recycling.Compared with the traditional semi automatic airer, automatic airer has more convenient and more convenient drying experience. With modern social science and technology and people of high quality of life, the pursuit of high efficiency factory, automatic airer will become the main development of the day after the goods market.
This design takes SIEMENS 300PLC as the core of the system's control and detection. To achieve the airer weight detection by the weighing sensor, and through the diode and to achieve overload alarm horn. The utility model can realize the lifting and lifting of the airing articles, and is tested by wind speed sensors, humidity sensors and temperature sensors when encountering strong wind, heavy rain and high temperature weather.No doubt, it can also be dried and recycled by hand. The software part adopts different functions of separate control design, realize the airer state function display and automatic operation. The design is simple and practical, and basically meets the design content and requirements.
