## 智能门铃 ### 样例简介智能门铃通过监控来访者信息，告诉主人门外是否有人按铃、有陌生人靠近或者无人状态。主人可以在数字管家中远程接收消息，并根据需要进行远程取消报警和一键开锁。同时，也可以通过室内屏幕获取门外状态。室内屏幕显示界面使用DevEco Studio 编写的js应用，具有很好的兼容和移植特性。硬件上采用了带有HDF框架的驱动模型，通过GPIO来获取传感器采集信息并驱动报警器进行动作。 ![image-20211228172423071](./media/image-01-local_ui_page.png) #### 运行效果

#### 样例原理 ![](./media/image-02-cloud_communication_page.png) 如上图所示，智能门铃整体方案原理图可以大致分成：智能门铃设备、数字管家应用、云平台三部分。智能门铃通过MQTT协议连接华为IOT物联网平台，从而实现命令的接收和属性上报。关于智能设备接入华为云IoT平台的细节可以参考 [连接IOT云平台指南](../iot_huawei/README.md)；智能设备同数字管家应用之间的设备模型定义可以参考[profile](../DistShedule_Profile/智能门铃profile定义.md) 。 #### 工程版本 + 系统版本/API版本：OpenHarmony 3.1 Beta + hb版本：0.4.4 + 工具链版本：gcc-arm-none-eabi-10.3-2021.10 ### 快速上手 #### 准备硬件环境 + 欧智通V200Z-R开发板 + 润和智能家居套件-红绿灯板 + 润和智能家居套件-炫彩灯板 + 预装HarmonyOS手机一台 **注：HarmonyOS是华为基于开源项目OpenHarmony开发的面向多种全场景智能设备的商用版本** #### 准备开发环境 ##### 安装必备软件开发基础环境由 windows 工作台和 Linux 编译服务器组成。windows 工作台可以通过 samba 服务或 ssh 方式访问 Linux编译服务器。其中 windows 工作台用来烧录和代码编辑，Linux 编译服务器用来编译 OpenHarmony 代码，为了简化步骤，Linux 编译服务器推荐安装 Ubuntu20.04。 ###### 安装编译依赖基础软件 ``` sudo apt-get install -y build-essential gcc g++ make zlib* libffi-dev git git-lfs ``` ###### 安装和配置Python + 打开Linux终端。 + 输入如下命令，查看python版本号，需要使用python3.7以上版本,否则参考 [系统基础环境搭建](https://gitee.com/openharmony/docs/blob/OpenHarmony_1.0.1_release/zh-cn/device-dev/quick-start/%E6%90%AD%E5%BB%BA%E7%B3%BB%E7%BB%9F%E5%9F%BA%E7%A1%80%E7%8E%AF%E5%A2%83.md)。 ``` python3 --version ``` + 安装并升级Python包管理工具（pip3）。 ``` sudo apt-get install python3-setuptools python3-pip -y sudo pip3 install --upgrade pip ``` + 设置pip的国内镜像 ``` pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple requests ``` ###### 安装hb + 输入如下命令确认hb是否为version 0.4.4 ``` hb -v ``` a. 若提示如下内容，则表示未安装可以从第2步开始操作。 ``` bash: /home/***/.local/bin/hb: No such file or directory ``` b.若提示如下内容，需要先卸载该版本，然后再执行第2步操作步骤。 ``` [OHOS INFO] hb version 0.4.3 ``` 卸载命令： ``` pip3 uninstall ohos-build ``` + 运行如下命令安装hb ``` pip3 install build/lite // 该命令需在OpenHarmony源码根目录下执行 ``` + 设置环境变量 ``` vim ~/.bashrc ``` 将以下命令拷贝到.bashrc文件的最后一行，保存并退出。 ``` export PATH=~/.local/bin:$PATH ``` 执行如下命令更新环境变量。 ``` source ~/.bashrc ``` + 再次执行”hb -v“，有以下版本显示则表示安装的hb版本正确。 ``` [OHOS INFO] hb version 0.4.4 ``` ##### 安装交叉编译环境在Linux编译服务器上搭建好基础开发环境后，需要安装OpenHarmony 编译V200Z-R平台特有的开发环境。 ###### 安装arm-none-eabi-gcc + 打开Linux终端。 + 下载[arm-none-eabi-gcc](https://gitee.com/link?target=https%3A%2F%2Fdeveloper.arm.com%2F-%2Fmedia%2FFiles%2Fdownloads%2Fgnu-rm%2F10.3-2021.10%2Fgcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2)编译工具。 + 安装[arm-none-eabi-gcc](https://gitee.com/link?target=https%3A%2F%2Fdeveloper.arm.com%2F-%2Fmedia%2FFiles%2Fdownloads%2Fgnu-rm%2F10.3-2021.10%2Fgcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2) 解压 [gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2](https://gitee.com/link?target=https%3A%2F%2Fdeveloper.arm.com%2F-%2Fmedia%2FFiles%2Fdownloads%2Fgnu-rm%2F10.3-2021.10%2Fgcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2) 安装包至~/toolchain/路径下。 ``` mkdir -p ~/toolchain/ tar -jxvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 -C ~/toolchain/ ``` 设置环境变量。 ``` vim ~/.bashrc ``` 将以下命令拷贝到.bashrc文件的最后一行，保存并退出。 ``` export PATH=~/toolchain/gcc-arm-none-eabi-10.3-2021.10/bin:$PATH ``` 生效环境变量。 ``` source ~/.bashrc ``` + 在命令行中输入如下命令，如果能正确显示编译器版本号，表明编译器安装成功。 ``` arm-none-eabi-gcc -v ``` #### 准备工程本用例采用repo的方式从码云官仓下载系统系统源码以及开发板适配代码，使用git从gitee的sig仓库拉取设备应用代码。 ##### 配置git -

在设备上电前需准备好安装了数字管家应用的HarmonyOS手机，详情见[数字管家应用开发](../digital_housekeeper_application/README_zh.md), 并在设置中开启手机的NFC功能； - 写设备NFC标签，详细操作见设备[NFC标签指导文档](../NFC_label_definition/README.md); - 烧录完成后，上电。开发者在观察开发板上状态LED灯以1Hz的频率闪烁时，将手机上半部靠近开发板NFC标签处； - 手机将自动拉起数字管家应用并进入配网状态，根据手机提示连接到设备热点teamX-DoorBell01后返回数字管家APP，输入路由账号密码，点击确定后，手机将信息传输到设备侧，设备开始联网。 ![](./media/image-23-net_config.gif) ##### 设备控制 + 有陌生人靠近: ![](./media/image-04-unkw_appr.gif) + 有人按门铃： ![](./media/image-05-calling_bell.gif) + 远程一键开门： ![](./media/image-06-open_door.gif) ### 参考资料 + [BES2600快速上手指导文档](../bes2600_quick_start/README.md) + [无感配网指南](../net_config/README.md) + [连接华为IoT云](../iot_huawei/README.md) + [NFC标签指导文档](../NFC_label_definition/README.md) + [数字管家应用开发](../digital_housekeeper_application/README_zh.md) + [知识体系](https://gitee.com/openharmony-sig/knowledge)
