【一起DIY】智慧校园防疫系统
本帖最后由 Hockel 于 2021-10-21 17:13 编辑## 作品背景：
2020年一开年，新冠病毒疫情肆虐全球，各国人民都生活在恐惧不安中，确诊病例数字也在天天变化，如今各大中小学都开学了，可是防疫工作成为重中之重。于是我们为中小学生设计这款智慧校园防疫系统。
## 功能设计
1、下位机使用是掌控板（EPS32）它主要用来连接网络并 显示时间、天气、今日疫情要闻、疫情数据实时查询、口罩识别测温等功能。
2、上位机使用的是Maix bit，使用maixhub训练的口罩识别模型（具体的口罩识别教程：可以参考我之前的文章：[【MaixPy 教程】用mixly玩转口罩识别](https://www.hockel.club/post/16146.html)），进而来检测学生是否佩戴口罩！
3、非接触红外测温传感器（mlx90614），用于测量学生的体温。4、人体红外热释电运动传感器，它用来检测是否有人通过，如果学生体温正常并且佩戴口罩，校区门杆就会由舵机控制打开。
4、Maix bit 与掌控板通过软串口进行通讯。
## 硬件清单
| 序列 | 硬件名称 | 数量 |
| ---- | ------------------------ | ---- |
| 1 | 掌控板 | 1 |
| 2 | 掌控宝 | 1 |
| 3 | Maix bit | 1 |
| 4 | mlx90614 | 1 |
| 5 | 人体红外热释电运动传感器 | 1 |
| 6 | 9G舵机 | 1 |
| 7 | 激光切割沙盘模型 | 1 |
## 电路连接
## 制作步骤
1、用laserbox画出该智慧校园防疫系统沙盘的主体结构：
2、对设计好的模型进行激光切割
3、小组组内开始进行组装
4、组装完成
## 上位机程序

## 总结
通过上面的教程，我对掌控板的物联网操作与Maix Bit 的口罩识别功能与体温检测功能有了更进一步的了解与掌握。当然里面有些功能可能比较简单，不喜勿喷哈！更多项目教程欢迎关注个人博客：(https://www.hockel.club/) 很好的案例呢，每次看作者的帖子都觉得很清晰明了 KIKI 发表于 2021-10-21 14:28
