Description: 本智能豆浆机的控制系统是基于AT89S52单片机来实现的，其主要功能有： 1.可以手动和自动对各种谷物和豆类进行加热和粉碎，工作模式分手动粉碎，手动加热和自动三种。 2.在豆浆机工作的过程中，数码管能给予温度和工作模式的显示。 3.在豆浆机工作过程中能对液位溢出和豆浆机干烧进行检查，发现后能蜂鸣报警并停止相关工作。 4.豆浆机工作完成时，能蜂鸣报警，提醒用户。 豆浆机的自动工作流程有软件控制：先判断是否干烧，再加热到80度，然后停止加热，进行粉碎并在间隙进行加热，再度检查液位，是否干烧，再进行加热，进入防溢延煮过程，防溢延煮后，发出报警声，提示豆浆已做好。液位溢出保护和防干烧保护用中断来控制，其检测由于没有防溢电极，功能用开关来模拟实现。-The intelligent soybean milk machine is implemented based on AT89S52 single chip microcomputer control system, its main functions are: 1. It can be manually and automatically to heat and crush all kinds of cereals and legumes, its work modes are divided into crushing , heating and automatic . 2. In the process of soybean milk machine work , digital tube can display temperature and working mode 3 . During the working process of the soybean milk machine , it can check overflow and soybean milk machine dry heating liquid level, after that the buzzer begin to alarm and the machine stop working.4. When the work of Soybean milk machine completed, the buzzer start to alarm ,and remind the user. The software control automatic workflow of Soybean milk machine: first to determine whether dry, and then heated to 80 degrees, then stop heating, and crushing and heated in clearance, and inspection level again, whether dry, heated again, enter spill-proof cooking process, prevent excessive delay a
