用vue canvas画一个能源电表和设备的监测图-CSDN博客

上一篇文章，我是用后端的数据来画出监测图。这次我觉的，用前端来控制数据，更爽。

本期实现功能：

1，得到监测设备和设备的数据，然后进行存库

2，得到监测设备和设备的关系流程图，然后可以生成图片

3，后期对设备进行监测，可以得知设备的正常状态或者是异常状态。

先上图片：

用法：

1.用户根据自己的监测设备和普通设备位置。在画布上绘出。

2.当用户绘制完后，导出数据则可获得所有的监测设备数据，设备数据，以及流程数据。

3.数据展示

}

4.根据数据，进行存库。type代表类型。connections则代表的每个设备之间的关系。

5.在来一张本地保存的图片：

6.后期根据设备的状态，来动态的修改设备的图片。来展示出设备的异常状态和正常状态。

7.这样，设备管理部分就可以轻松搞定了。

欢迎各位大佬点评。
