"""FilmForge 温控闭环自动测试（COM5，RS485）。
|
||
|
||
固定测试序列：M999(版本) -> M2S500(0.5s 上报) -> M4S50(目标) -> M3S1(加热)
|
||
-> 采样 DURATION 秒 -> M3S0/M2S0 收尾。
|
||
|
||
不设温度上限（用户明确：真机靠物理温度开关保护，测试环境上限由用户控制）。
|
||
|
||
判定标准（脚本自动输出，不掺人工解释）：
|
||
J1 上报流：>2 帧/s 连续； J2 稳态窗（最后 300s）：|均值-目标|<=0.5C
|
||
J3 稳态窗极值：[目标-0.5, 目标+0.5]（用户规格 ±0.5C）
|
||
J4 无 OPEN/SHRT 故障值
|
||
输出：test_data.csv（t,temp 全序列）+ test_events.log（全部收发）+ 终端摘要。
