# GB/T 32960 黄金样本集
|
||||
|
||||
> 本目录用于回放测试与双跑对账。所有样本从旧服务 `lingniu-vehicle-data-reception` 线上抓包后脱敏（VIN 替换为 `LTEST<序号>XXXXXXXX`）。
|
||||
|
||||
## 文件命名
|
||||
|
||||
```
|
||||
<命令类型>_<场景>_<序号>.hex
|
||||
```
|
||||
|
||||
命令类型取自 `CommandType` 枚举：
|
||||
- `vehicle_login` (0x01)
|
||||
- `realtime_report` (0x02)
|
||||
- `resend_report` (0x03)
|
||||
- `vehicle_logout` (0x04)
|
||||
- `heartbeat` (0x07)
|
||||
|
||||
## 文件格式
|
||||
|
||||
每个 `.hex` 文件是一行紧凑十六进制，字节之间**无分隔符**。
|
||||
行首允许以 `#` 开头写注释，测试代码忽略注释行与空行。
|
||||
|
||||
示例 `realtime_report_basic_001.hex`:
|
||||
```
|
||||
# 2017-05-21 10:00:00 宇通 YT01，SOC 70%，车速 52.3 km/h

|
||||
```
|
||||
|
||||
## 新增样本步骤
|
||||
|
||||
1. 从生产抓包工具（tcpdump / rg-samples）导出一帧完整字节（含 `0x23 0x23` 起始和 BCC 尾）
