2、机的精准性，而且避 免了传统人工操作所产生的不必要误差。 本文中所设计的混凝土自动加料机采用以单片机为核心的自动控制系统，具备满料检 查功能，并能够通过LED显示器显示出输送、排料、满料时间。根据所加物料的不同，本 文所设计的自动加料控制系统应用广泛，既可以运用到建筑工程中混凝土的配置搅拌，也 可以运用到现代医药生产中涉及的真空药物粉末粒子的加料混合。单片机加料控制系统采 用自动控制技术大大提高了工作的效率，不仅满足了自动控制各种动作状态要求，也满足 了用户对不同使用环境的需要，在当下具有广阔的发展前景。 关键词：关键词：自动控制自动控制；单片机；加料机；单片机；加料机 毕业设计 - II -

3、 Abstract The traditional concrete feeding machine has to add the mixture by peoples working experiences. But it is very easy to make the concrete wasted, once there has a mistake with the workers wrong operations. With the rapid development in recent years, using a combination of hardware and softw

4、are control system can not only save labor costs, but also make the intelligent operation possible. The automatic control systems improve the accuracy of the feeding machines, and also avoid the unnecessary errors generated by the traditional manual operations. Microcontroller is the core of the aut

5、omatic control system for the concrete feeding machine in the essay. And the transportation, nesting and full feeding time can be displayed by the LED. Depending on the materials, the design of automatic feeding control systems are widely used, both can be applied to the configuration of the concret

6、e construction projects stirring, also can be applied to the vacuum drugs involved in the feeding of the powder particles mixed in the modern pharmaceutical production. Microcontroller feeding control system with automatic control technology can greatly improve the efficiency of the work, not only to meet the automatic control of a variety of actions state requirements, but also to meet the needs of users of different use of the environment. And it has broad
