实训台接线:串口要选对。接线做成数据(BoardState.wiring),默认按教材布局图 COM2 ADAM-4017+、COM3 ADAM-4150、COM4 ZigBee 协调器、COM5 LED 屏,实验可在 meta.json 的 wiring 里改:项目 7 的书上代码在一个串口上打开两个模块,这三个实验把 4150 并到 COM2 的 485 总线上。选错串口时返回值照反编译的真机版 dll(4017 全 null、4150 全 false,4150 的 OnOff 和 LED 推送返回成功但设备不动作,ZigBee 返回 false);串口没打开时照教材仿真版。Open / Close / 没打开就读写报告给服务器,实训台最上方用红字提示("程序在 COM2 上打开 ADAM-4150,它接在 COM3""ADAM-4150 的串口没有打开,程序却在读写它"),评分不通过时也附上。只读接线展示:鼠标移到实训台设备上,标题栏写出线路,对应通道、模块、串口高亮;串口服务器按接线列出设备,程序打开的口亮绿点;程序里串口下拉框的灰字按当前接线。打开实验时浏览器发 experiment 消息换接线,老师看学生提交时按作业的实验接线(提交接口返回 sampleId)。"4017"统一写成 ADAM-4017+
上课前逐个检查 23 个实验后的修改:补上三处评分漏洞(项目 3 任务 1、项目 4 任务 3 的关闭和项目 7 任务 2 的熄灯,程序什么都不做也能通过);评分说明的空格;任务说明按实测补充(项目 2 任务 1–3、项目 3 任务 2、项目 4 任务 2、项目 7 任务 1–3、项目 8 任务 5)。使用说明、设计方案同步,设计方案记下以后可能扩展"物联网设备安装与调试"课 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
