在婴儿培养箱使用的过程中，医护人员会根据具体情况对温度、湿度等参数进行设置或修改，安装和维护人员也会对系统中的一些参数进行调整，为了便于以上的修改，在婴儿培养箱控制系统中往往接入一个小键盘来读取数值。本设计主要介绍通过AT89C51单片机与MAX7219显示驱动芯片的连接如何来驱动LED显示，并通过3个按键即输入键盘对所选数值进行加1、减1的操作，从而完成对温度、湿度类似数值的修改。
首先通过对AT89C51单片机及MAX7219显示驱动芯片的研究来了解它们的详细用法，给出硬件设计，并用PROTEL 99画出具体的电路图；其次，对键盘编码方案及两种键盘工作方式即中断方式和查询方式进行研究，并结合AT89C51单片机及MAX7219显示驱动芯片的详细用法进行软件设计，用C语言编写程序并画出流程图，完成后用KEIL软件进行编译；最后，通过星研软件对之进行仿真调试，改变不同的变量查看结果的正确性。
请自行帮我翻译，不要用翻译软件！

The use of infant incubators in the process, the medical staff will be based on the specific circumstances of temperature, humidity and other parameters or modify settings, installation and maintenance of the system will also be some adjustment of parameters, in order to facilitate the above changes, the baby train box access control system is often a small keyboard to read the value. Introduced through the design AT89C51 single-chip and MAX7219 display driver chip connected to drive the LED display of how, and through that the three keys on the keyboard input to the selected value plus 1, minus 1 of the operation, the completion of temperature, humidity similar numerical changes.
First of all, through the AT89C51 single-chip and MAX7219 display driver chip research to understand the details of their usage, given the hardware design, and draw PROTEL 99 specific circuit; Secondly, the encoding scheme of the keyboard and the keyboard work in two ways that the interruption approac
