基于单片机的食堂饭菜的保温系统
摘要:随着人们生活水平的进步，人们越来越注重自己的饮食问题，因此各种各样的保温器材开始出现，例如:保温杯、保温饭盒、保温柜等。他们都可以在一定的时间内保证放入物品的温度没有太大的改变，以达到“保温”的效果。然而，对于食堂来说，以上的方法并不实用。这就需要我们利用保温控制器来控制，从而极大的方便食堂管理人员对饭菜温度的需求，使得食堂对食用者更加的负责，因此该温度控制系统在未来会有非常广阔的市场。本文对该控制仪器经行了简单的分析设计。
本系统主要能够完成一下的功能：采集容器底部的温度状态，并送入中控模块，主控模块根据现有的温度判断是否是保持原来温度状态还是需要启动加热设备进行加温处理，并有指示灯给予提示，具有一定的操作性，比较方便的进行温度控制的功能。
该系统采用单片机控制技术对升温功能进行提升改进，从而使得保温控制器可以自动控制。又能够根据用户的需要而自行的调节。通过本课题的，使食堂对饭菜的保温得到了增强，对其他物品的保温有非常重要的意义和应用价值。

Insulation system design based on SCM cafeteria food
Abstract：As people's living standards progress, more and more people pay attention to their diet problems, so a variety of insulating equipment began to appear, such as: mug, insulation boxes, cabinet and so on. They can be guaranteed into the article temperature has not changed much in a certain period of time to achieve the "insulation" effect. However, canteens, the above methods are not practical. This requires us to use a controller to control the heat, thereby greatly facilitate the management staff canteen demand for food temperature, making the cafeteria more responsible eaters, so the temperature control system in the future will have a very broad market. In this paper, the control instrument is a simple line of analysis and design.
This system is mainly to complete the look of functions: to collect temperature state of the container bottom and fed to the control module, the control module is whether to maintain the original temperature state or the need to start the heating apparatus for heating process according to the existing temperature judgment, and there are lights to give tips, This system adopts single-chip microcomputer control technology to improve heating function improvement, so as to make the insulation controller can control automatically. Can according to the needs of users and to adjust again. Through this topic, the dining room of food preservation has been enhanced, the heat preservation of other items have very important significance and application value.
Key words: Heating equipment; Control system; Single chip microcomputer; Temperature detection;
