MATLAB基于几何图形法的障碍物地图构建算法
这是一份关于MATLAB基于几何图形法的障碍物地图构建算法的源代码，是我总结的自己关于线性规划的构图方法的理解，里面包含四个matlab的函数，可以直接调试，没有主函数，直接运行需要自己提供输入参数，具体参数代码注释的很详细，不理解的可以看我写的博客，link:https://blog.csdn.net/SimileciWH/article/details/83958617

抄表器程序
一般来说，采用RS485最简单。你要有上位机软件，也就是电脑上要装一个抄表程序，还有通讯线连接到电表通讯线输出上，还有就是电表了，有了这几个，最主要的是每个部分的通讯协议要一样的，还有就是每个部分连接的参数要相互统一。
