+# 升级模块部署、测试和使用说明
+
+## 模块组成
+
+- updater.py
+
+升级主模块.
+
+监听mqtt topic:  /device/ota/init/<盒子SN>
+
+发布mqtt topic: /device/ota/update
+
+- evupdater.service
+
+升级模块systemd服务描述文件
+
+
+
+## 升级模块工作流程
+
+- 盒子启动后自动监听 mqtt: /device/ota/init/<盒子SN>
+- 升级包发布者将打包好的升级文件上传到可访问的http server.
+
+打包:
+
+```bash
+mkdir /opt/evbox-update
+cd /opt/evbox-update
+mkdir -p bin lib
+# copy evslicer evp* evm* to bin
+# copy libs* to lib
+# add optional run.sh
+zip -r update.zip bin lib
+```
+
+- 编辑并发送升级MQTT命令消息(JSON)
+
+```json
+{
+    "sn": "<盒子序列号>",
+    "sku": "ILSA-HW-TM0401",
+    "firmware": "0.1.1",
+    "url": "升级包的http地址", //例如: "http://118.31.8.63:8080/update.zip",
+    "batchId": "121"
+}
+
+```
+
+使用mqtt dashboard或者其他工具及软件向: /device/ota/init/<盒子SN> 发送上面的升级命令消息.
+
+- 反向登陆到盒子查看日志
+
+每下载1600KB会有一个下载打印日志.  升级完成也会发布一个complete消息
+
+```bash
+tail -f /var/log/syslog|grep updater
+```
+
+
+
+## 手动部署升级模块步骤
+
+- 反向登陆旧版本的盒子
+- 获取 updater.py
+
+```bash
+cd /root/work/opencv-pocs/opencv-motion-detect
+# apt install wget -y
+wget -O updater.py https://gitlab.devops.intelab.cloud/root/evsuits/raw/master/opencv-motion-detect/updater.py
+chmod +x updater.py
+```
+
+- 获取并配置evupdater.service
+
+```bash
+cd /etc/systemd/system
+wget -O evupdater.service https://gitlab.devops.intelab.cloud/root/evsuits/raw/master/opencv-motion-detect/deployment/evupdater.service
+
+systemctl enable evupdater
+systemctl start evupdater
+```
+
+- 发送升级消息测试是否可用
+
+可以发任意消息, 监听/device/ota/update看盒子是否有正确的回复.
