# Go Vehicle Gateway 旁路验证记录
|
||
|
||
验证时间：2026-07-01 22:00-22:10 CST
|
||
|
||
## 部署版本
|
||
|
||
- Git commit：`60ca42e`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-60ca42e-20260701220622`
|
||
- 部署方式：ECS `115.29.187.205` 上 Docker Compose 旁路部署
|
||
- Compose 目录：`/opt/lingniu-go`
|
||
|
||
## 旁路端口和 topic
|
||
|
||
为了不影响现有 Java 生产服务，本次没有占用生产端口和生产 topic。
|
||
|
||
| 项 | 值 |
|
||
|---|---|
|
||
| GB32960 旁路 TCP | `115.29.187.205:23296 -> container :32960` |
|
||
| JT808 旁路 TCP | `115.29.187.205:18080 -> container :808` |
|
||
| Realtime API | `115.29.187.205:20210` |
|
||
| GB32960 RAW topic | `vehicle.raw.go.gb32960.v1` |
|
||
| JT808 RAW topic | `vehicle.raw.go.jt808.v1` |
|
||
| Yutong MQTT RAW topic | `vehicle.raw.go.yutong-mqtt.v1` |
|
||
| Unified topic | `vehicle.event.go.unified.v1` |
|
||
|
||
## 容器状态
|
||
|
||
ECS 上四个 Go 容器均已启动：
|
||
|
||
```text
|
||
go-vehicle-gateway Up
|
||
go-history-writer Up
|
||
go-stat-writer Up
|
||
go-realtime-api Up
|
||
```
|
||
|
||
## Kafka 验证
|
||
|
||
向 `18080` 注入 JT808 样例帧后，`vehicle.raw.go.jt808.v1` 和
|
||
`vehicle.event.go.unified.v1` 均消费到统一 JSON envelope。
|
||
|
||
样例解析结果包含：
|
||
|
||
- `protocol=JT808`
|
||
- `message_id=0x0200`
|
||
- `phone=013307795425`
|
||
- `longitude=121.069881`
|
||
- `latitude=30.590151`
|
||
- `speed_kmh=23`
|
||
- `total_mileage_km=10241.2`
|
||
- 表 27 附加项 `0x01` 原始值 `0001900C`
|
||
|
||
## TDengine 验证
|
||
|
||
目标库：`lingniu_vehicle_ts`
|
||
|
||
```text
|
||
raw_frames count = 3
|
||
vehicle_locations count = 2
|
||
vehicle_mileage_points count = 2
|
||
```
|
||
|
||
最新 RAW 标识：
|
||
|
||
```text
|
||
GB32960 | LNBSCB3D4R1234567 | LNBSCB3D4R1234567 |
|
||
JT808 | JT808:013307795425 | | 013307795425
|
||
JT808 | JT808:013307795425 | | 013307795425
|
||
```
|
||
|
||
说明：JT808 样例 phone 当前没有在 `vehicle_identity_binding` 中解析到 VIN，因此
|
||
TDengine tag 使用 `vehicle_key=JT808:013307795425`。
|
||
|
||
## Redis 验证
|
||
|
||
向 `23296` 注入带 VIN 的 GB32960 合成帧后，Realtime API 可查询：
|
||
|
||
```text
|
||
GET /api/realtime/vehicles/LNBSCB3D4R1234567
|
||
```
|
||
|
||
返回字段包含：
|
||
|
||
- `vin=LNBSCB3D4R1234567`
|
||
- `protocols=["GB32960"]`
|
||
- `online=true`
|
||
- `speed_kmh=30`
|
||
- `total_mileage_km=10000`
|
||
- `soc_percent=85`
|
||
- `longitude=121`
|
||
- `latitude=30.56`
|
||
|
||
## MySQL 统计验证
|
||
|
||
向 `23296` 注入带 VIN 的 GB32960 合成帧后，`vehicle_daily_metric` 写入：
|
||
|
||
```text
|
||
LNBSCB3D4R1234567 | 2020-07-01 | GB32960 | daily_mileage_km | 0.000 | 10000.000 | 10000.000 | 1
|
||
LNBSCB3D4R1234567 | 2020-07-01 | GB32960 | daily_total_mileage_km | 10000.000 | 10000.000 | 10000.000 | 1
|
||
```
|
||
|
||
说明：本次 GB32960 合成帧的设备时间为测试值，因此统计日期为 `2020-07-01`。
|
||
|
||
## 已修复问题
|
||
|
||
- TDengine WebSocket 普通 `INSERT` 使用参数占位符时，字符串未按预期加引号，导致语法错误。已在 `60ca42e` 中改为显式 SQL literal 转义。
|
||
- MySQL Go DSN 中 `charset=utf8mb4%2Cutf8` 会被 driver 传给 MySQL，导致语法错误；ECS 旁路 env 已改为 `charset=utf8mb4`。
|
||
- TDengine ECS 当前可用 root 密码与早先记录不一致，本次旁路 env 已按实际可认证值修正。
|
||
|
||
## 未完成
|
||
|
||
- 未切换真实生产端口 `32960/808`。
|
||
- 未将真实外部 32960/808 流量转发到 Go 旁路端口。
|
||
- 未开启宇通 MQTT 正式订阅。
|
||
- JT808 样例未解析到 VIN，需维护 `vehicle_identity_binding` 后再验证 808 每日统计。
