edge_demo's Introduction

此处是《边缘计算:原理、技术与实践》的系统实践代码仓库,请配合书中第12章的步骤展开实践。

系统目标

从0开始实现边缘计算系统,特别面向物联网场景的计算卸载过程。

目标1:自主实现定制化边缘服务器

为没有图像处理能力的前端物联网设备提供边缘计算服务,包括物联网设备及边缘服务器两端。

  • 物联网前端:发起计算请求、响应计算结果
  • 边缘服务器端:运行服务、处理请求、返回计算结果

逻辑架构图

目标2:利用EdgeX快速搭建标准化边缘服务器

书中过程基于EdgeX官方文档实现,原版教程在这里。 中文实现过程请参考书中描述。

硬件使用

  • 物联网前端设备:ESP32-Cam
  • 显示屏:SSD1306
  • 边缘服务器:树莓派3B+或4B(可以使用x86服务器,书中提到的依赖服务请按照相应的系统版本准备
  • 树莓派系统版本:RPI OS Buster
ESP32-Cam SSD-1306 树莓派

代码说明

  • Tensorflow提供的目标检测代码请使用9241dd1版本
  • Docker镜像基础系统使用Python的Docker Hub官方镜像,版本:python:3.7-slim-buster
  • 读者可考虑直接使用书中搭建好的服务器端服务镜像(版本使用v2)。
