【开源】智能培养室

一、简介
本开源项目是一个智能培养室，可用于学校实验室，工程研究院，化学化工厂，材料研究院等。它是基于环境的湿量，温度，高度的等物理量来满足实验的基本环境，有加热模块和风机来控温和调温，有电源功率可调来驱动多路光照，培养实验所需的恒定光强，风量等。可以开启一键高效模式，让仪器按照用户设定的参数和系统标定的参数进行自动运行，无需过度的人为干预，当系统检测到危险时，仪器会记录下此故障号，还可以不使用模拟光照，而采用大自然的光，通过窗帘偏移位置和传感器来实时反馈调节的，为科创实验发挥一点点作用!

接下来，让我们直入主题吧，硬件上有rs485接口，配合modbus协议和各种从机配合实现整个功能。

二、GUI工程
图标素材

图片素材

DGUS Tool主界面

菜单界面

用户基础参数

维护标定参数

还有欢迎界面, 全键盘界面, 确认输入界面等请自行查看GUI工程。

三、C51工程
C51的代码量很大，这里就以核心代码为举例，那就是主界面的代码，还有modbus的主处理主界面的:
