2023年电赛综合测评B题国一方案
本装置可测量：同轴线缆的长度、终端电阻负载、终端电容负载。
主控使用梁山派开发板，代码开发环境为STM32CubeMX+CLion+OpenOCD。
长度测量采用TDR时域反射法，误差小于0.5cm；电阻负载测量使用分压法，误差小于0.1Ω；电容负载测量使用NE555振荡电路，误差小于1pF。
一、题目要求
设计并制作一个同轴电缆长度与终端负载检测装置，如图1所示。待测电缆始端通过电缆连接头与装置连接，电缆终端可开路或接入电阻、电容负载。 设置“长度检测”和“负载检测”两个按键，用以选择和启动相应功能。负载电阻值范围 10Ω~30Ω 电容值范围 100pF~300pF。 装置由不大于6V的单电源供电。
基本要求
10m ≤ 线缆长度 ≤ 20m，终端开路，测量长度，误差不大于 5%
保持长度不变，终端接入电阻或电容负载，正确判断负载类型
发挥部分
10m ≤ 线缆长度 ≤ 20m，终端开路，测量长度，误差不大于 1%
保持长度不变，终端接入电阻或电容负载，正确判断负载类型并测量值，误差不大于 10%
线缆长度 ≤ 1m，测量长度，误差不大于 1%
