+## 城科水电监控
+
+**进行水费和电费的实时监控程序， 默认获取前24条数据进行绘图**
+
+### 实现功能
+
+- 获取**水费**和**电费**使用情况
+- 使用 `matplotlib` 进行绘图可视化
+- 使用企业微信机器人进行推送图片
+
+### 使用
+
+- 配置当前目录下的 `config.py` 文件
+
+    - 手动去 Github 下载 [LXGWWenKai-Medium 字体](https://github.com/lxgw/LxgwWenKai) 保存到fonts文件夹中，或者使用 wget 进行获取，然后修改配置文件
+  
+        ```sh
+        curl -L -o ./fonts/LXGWWenKaiMono-Medium.ttf https://github.5700.cf/https://github.com/lxgw/LxgwWenKai/releases/download/v1.521/LXGWWenKaiMono-Medium.ttf
+        ```
+
+    - `UID` 获取，使用支付宝进行扫描下方二维码即可获得 `uid`
+
+        ![UID 获取](./images/image.png)
+
+
+    - `USER_NO` 获取，通过抓包获取，使用抓包软件进行抓取微信小程序**扫呗团餐**，对响应体进行搜索`user_no`即可
+
+        ![USER_NO 获取](./images/image2.png)
+
+    - `SCHOOL_ACCOUNT` 这是学号（可选）
+    - `USER_NAME` 这是姓名（可选）
+    - `WECHAT_COMANY_BOT_KEY` 企业微信机器人 key
+
+
+- 安装依赖
+
+    ```sh
+    pip install aiosqlite apscheduler httpx matplotlib
+    ```
+
+- 通过 `scheduler.py` 修改监控时长配置（不懂的请问 AI）
