# 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。
|
||
|
||
## 2026-07-01 22:22 真实归档帧复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`5f4f4fd`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-5f4f4fd-20260701222128`
|
||
|
||
本轮补充验证内容：
|
||
|
||
- JT808 支持 2019 版 versioned header，真实帧 `0x0200` 可解析出 `phone=14894135060`、`longitude=117.178187`、`latitude=30.570155`、`speed_kmh=33.4`、`total_mileage_km=7868.9`。
|
||
- GB32960 真实燃料电池帧 `VIN=LB9A32A21R0LS1707` 可解析 `0x01` 整车、`0x02` 驱动电机、`0x03` 燃料电池、`0x04` 发动机、`0x05` 位置、`0x06` 极值、`0x07` 报警、`0x08` 电压、`0x09` 温度；后续 `0x30` 广东燃料电池扩展暂以 unknown raw 保留。
|
||
- GB32960 真实帧字段包含 `fuel_cell_hydrogen_consumption_kg_per_100km=1.8`、`longitude=120.800326`、`latitude=31.634907`、`total_mileage_km=53490.9`。
|
||
- Realtime API `GET /api/realtime/vehicles/LB9A32A21R0LS1707` 已返回上述经纬度和氢耗字段。
|
||
- TDengine `vehicle_locations` 和 `vehicle_mileage_points` 已写入真实 GB32960 位置和里程点：
|
||
|
||
```text
|
||
2020-07-01 08:09:22 | GB32960 | LB9A32A21R0LS1707 | lon=120.800326 | lat=31.634907 | mileage=53490.9
|
||
```
|
||
|
||
后续仍需补齐：
|
||
|
||
- JT808 真实 phone `14894135060` 仍未解析到 VIN，需维护身份绑定后再验证 VIN 维度实时和统计。
|
||
|
||
## 2026-07-01 22:28 广东燃料电池扩展复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`a15de91`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-a15de91-20260701222743`
|
||
|
||
本轮补充验证内容：
|
||
|
||
- GB32960 真实燃料电池帧 `VIN=LB9A32A21R0LS1707` 的 vendor 尾部已从 `unknown_unit` 补为结构化块：
|
||
`0x30 gd_fc_stack`、`0x31 gd_fc_auxiliary`、`0x32 gd_fc_dcdc`、`0x33 gd_fc_air_conditioner`、
|
||
`0x34 gd_fc_vehicle_info`、`0x80 gd_fc_demo_extension`、`0x83 gd_fc_vendor_tlv`。
|
||
- Kafka `vehicle.raw.go.gb32960.v1` 最新消息包含上述 block，并输出关键扁平字段：
|
||
`gd_fc_stack_hydrogen_inlet_pressure_kpa=97`、`gd_fc_stack_cell_count=108`、
|
||
`gd_fc_vehicle_hydrogen_mass_kg=4.3`、`gd_fc_demo_stack_temp_c=65`。
|
||
- Realtime API `GET /api/realtime/vehicles/LB9A32A21R0LS1707` 已返回 vendor 扁平字段：
|
||
|
||
```text
|
||
gd_fc_dcdc_controller_temp_c=47
|
||
gd_fc_demo_stack_temp_c=65
|
||
gd_fc_stack_cell_count=108
|
||
gd_fc_stack_frame_cell_count=108
|
||
gd_fc_stack_hydrogen_inlet_pressure_kpa=97
|
||
gd_fc_stack_water_outlet_temp_c=65
|
||
gd_fc_vehicle_hydrogen_mass_kg=4.3
|
||
```
|
||
|
||
- TDengine `raw_frames` 中 GB32960 行数增加到 `4`，最新 RAW 标识：
|
||
|
||
```text
|
||
2026-07-01 14:28:24.869 | 172.20.0.1:47082 | GB32960 | LB9A32A21R0LS1707 | OK
|
||
```
|
||
|
||
后续仍需补齐：
|
||
|
||
- JT808 真实 phone `14894135060` 到 VIN 的绑定数据维护与统计复验。
|
||
- Go 旁路尚未切换到生产 `32960/808` 端口；仍运行在 `23296/18080`。
|
||
|
||
## 2026-07-01 22:43 JT808 前导零 phone 身份解析复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`6b55694`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-6b55694-20260701224300`
|
||
|
||
本轮修复内容：
|
||
|
||
- JT808 2011 老版包头的终端手机号按 BCD[6] 解析会保留前导 `0`，例如包头为 `013079963379`。
|
||
- `vehicle_identity_binding.phone` 中实际维护的是去前导零后的手机号 `13079963379`。
|
||
- 身份解析候选键已调整为先查原始 phone，再查去前导零 phone，之后再按 `device_id`、`plate` 降级。
|
||
|
||
真实帧复验样本：
|
||
|
||
- 归档帧：`/opt/lingniu/vehicle-ingest/gb32960/archive/2026/07/01/JT808/unknown/1782903942845000.bin`
|
||
- 消息：`0x0200` 位置信息汇报
|
||
- 包头 phone：`013079963379`
|
||
- 绑定表 phone：`13079963379`
|
||
- 解析 VIN：`LKLG7C4E3NA774736`
|

|
||
```
|
||
|
||
说明：该真实位置帧携带的表 27 附加项 `0x01` 总里程值为 `0`，因此本次只验证身份解析、链路落地和差值统计写入；要验证非零日里程，需要回放或等待同一 VIN 的非零总里程连续位置点。
|
||
|
||
## 2026-07-01 22:55 Kafka 发布重试部署复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`7e7066d`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-7e7066d-20260701225503`
|
||
|
||
本轮修复内容：
|
||
|
||
- gateway 的 Kafka 发布增加同步重试封装。
|
||
- 默认配置：
|
||
- `KAFKA_PUBLISH_ATTEMPTS=3`
|
||
- `KAFKA_PUBLISH_BACKOFF_MS=100`
|
||
- `KAFKA_PUBLISH_TIMEOUT_MS=3000`
|
||
- RAW 仍先于 unified event 写入；RAW 写失败不会继续写 unified。
|
||
- 单元测试覆盖首次失败后成功、重试耗尽返回错误、上下文取消时停止重试。
|
||
|
||
部署后容器状态：

```
|
||
|
||
说明：当前重试层只能覆盖 Kafka 短暂抖动；如果 Kafka 长时间不可用，仍需后续增加本地磁盘 spool/WAL 和恢复补发。
|
||
|
||
## 2026-07-01 23:02 切换 Go 到生产 32960/808 端口
|
||
|
||
本轮操作：
|
||
|
||

||
- `vehicle-analytics-app`
|
||
- `vehicle-state-app`
|
||
- `telemetry-field-parser-app`
|
||
- 保留 Go sidecar 和 Portainer agent。
|
||
- 修改 `/opt/lingniu-go/.env`：
|
||
- `GO_GB32960_TCP_PORT=32960`
|
||
- `GO_JT808_TCP_PORT=808`
|
||
- Go gateway 使用镜像：

|
||
- 开启 Kafka 本地 spool：
|
||
- host：`/opt/lingniu-go/spool/gateway`
|
||
- container：`/data/spool/gateway`
|
||
|
||
端口验证：

|
||
|
||
说明：生产 808 中仍有部分 phone 未解析出 VIN，后续需要继续维护 `vehicle_identity_binding` 的 phone/device_id/plate 到 VIN 映射，或者增强 808 注册/鉴权帧中的 identity 回写。

## 2026-07-01 23:09 808 里程统计防 0 污染复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`d347525`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-d347525-20260701230845`
|
||
|
||
本轮修复内容：
|
||
|
||
- `stat-writer` 不再把 `total_mileage_km <= 0` 的采样写入 MySQL 每日指标。
|
||
- MySQL upsert 对历史 `first_total_mileage_km=0` / `latest_total_mileage_km=0` 做纠偏；后续首次有效总里程会替换掉历史 0。
|
||
- `realtime-api` 合并实时快照时，非正 `total_mileage_km` 不再覆盖已有正值；速度、位置、状态等其他字段仍按事件时间更新。
|
||
|
||
测试验证：
|
||
|
||
```text
|
||

|
||
```
|
||
|
||
生产回放验证：
|
||
|
||
- 第一条 808 帧：`device_time=2026-07-01T23:09:35+08:00`，`total_mileage_km=12345.6`
|
||
- 第二条 808 帧：`device_time=2026-07-01T23:09:36+08:00`，`total_mileage_km=0`
|
||
- 两条帧使用同一 VIN：`LKLG7C4E3NA774736`
|
||
|
||
Redis merged 快照确认：第二条 0 里程帧没有覆盖已有有效总里程。

|
||
```
|
||
|
||
MySQL `vehicle_daily_metric` 确认：0 里程采样未进入统计，sample_count 只因有效总里程采样增加一次。
|
||
|
||
```text
|
||
LKLG7C4E3NA774736 | JT808 | 2026-07-01 | daily_mileage_km | 0.000 | sample_count=13 | first=12345.600 | latest=12345.600
|
||
LKLG7C4E3NA774736 | JT808 | 2026-07-01 | daily_total_mileage_km | 12345.600 | sample_count=13 | first=12345.600 | latest=12345.600
|
||
```
|
||
|
||
说明：生产 TDengine 中已经存在大量 808 非零 `total_mileage_km` 采样，但许多 phone 尚未映射到 VIN，因此 MySQL 按 VIN 的统计只会覆盖已解析 VIN 的车辆。下一步应继续补齐 `vehicle_identity_binding`，让更多 808 车辆进入统计。

## 2026-07-01 23:23 808 注册身份自动维护复验
|
||
|
||
部署版本已更新：
|
||
|
||
- Git commit：`7b44f97`
|
||
- 镜像：`crpi-85r4m0ackrm3qpje.cn-shanghai.personal.cr.aliyuncs.com/oneos/vehicle-gateway-go:go-7b44f97-20260701232200`
|
||
|
||
本轮修复内容：
|
||
|
||
- 808 `0x0100` 注册帧解析 `province`、`city`、`manufacturer`、`device_type`、`device_id`、`plate_color`、`plate`。
|
||
- 808 `0x0102` 鉴权帧解析 `auth_token`。
|
||
- Go gateway 在 identity resolve 后写入 `jt808_registration`，普通上行也会刷新 `latest_seen_at`。
|
||
- 注册帧通过车牌解析到 VIN 后，会尝试把 phone/device/plate 反写到 `vehicle_identity_binding`。
|
||
- 注册帧车牌支持 GBK 解码，避免 `Incorrect string value` 写入错误。
|
||
|
||

|
||
|
||
生产日志确认：
|
||
|
||
- 新版本启动后真实 808、32960 连接持续进入。
|
||
- GBK 车牌注册帧不再出现 `Incorrect string value`。

|
||
```
|
||
|
||
说明：`jt808_registration.phone` 保存 808 包头原始 phone；`vehicle_identity_binding.phone` 中已有部分去前导零 phone。Go resolver 会同时查询原始 phone 和去前导零 phone。
|
||
|
||
## 2026-07-01 23:28 生产链路与指标清理复验
|
||
|
||
本轮复验目标：
|
||
|
||
- 确认 Go gateway 的 Kafka durable spool 是重启窗口残留，而不是持续发布失败。
|
||
- 确认 stat-writer / history-writer / realtime-api 的 Kafka consumer group 无 lag。
|
||
- 确认真实 808 车辆 registration、TDengine RAW/里程点、Redis 实时查询均在持续更新。
|
||
- 清理之前生产合成回放产生的 JT808 当日指标测试数据。
|
||
|
||
Kafka topic / consumer group：
|
||
|
||
```text
|
||
vehicle.raw.go.jt808.v1 有持续 offset
|
||
vehicle.raw.go.gb32960.v1 有持续 offset
|
||
vehicle.event.go.unified.v1 有持续 offset
|
||
|
||
go-stat-writer LAG=0
|
||
go-history-writer LAG=0
|
||
go-realtime-api LAG=0
|
||
```
|
||
|
||
TDengine：
|
||
|
||
```text
|
||
raw_frames:
|
||
JT808 2922
|
||
GB32960 27
|
||
|
||
vehicle_mileage_points:
|
||
JT808 2050
|
||
GB32960 2
|
||
```
|
||
|
||
Redis 实时查询样例：
|
||
|
||
```text
|
||
GET /api/realtime/vehicles/LKLG7C4E3NA774736
|
||
vin=LKLG7C4E3NA774736
|
||
source_endpoint=222.66.200.68:29646
|
||
plate=沪A06788F
|
||
longitude=119.556866
|
||
latitude=29.047911
|
||
total_mileage_km=12345.6
|
||
```
|
||
|
||
说明：该 Redis merged 快照保留了此前有效 `total_mileage_km=12345.6`，后续真实 808 位置帧上报的 `total_mileage_km=0` 不会覆盖该字段。TDengine 中该 VIN 后续真实里程点的 `total_mileage_km` 均为 0，因此 stat-writer 按“只统计正总里程”的规则不再写 JT808 每日指标。
|
||
|
||
MySQL 指标清理：
|
||
|
||
```text
|
||
删除前：
|
||
LKLG7C4E2NA774775 | JT808 | 2026-07-01 | daily_mileage_km | first=0 | latest=0 | sample_count=7
|
||
LKLG7C4E2NA774775 | JT808 | 2026-07-01 | daily_total_mileage_km | first=0 | latest=0 | sample_count=7
|
||
LKLG7C4E3NA774736 | JT808 | 2026-07-01 | daily_mileage_km | first=12345.6 | latest=12345.6 | sample_count=13
|
||
LKLG7C4E3NA774736 | JT808 | 2026-07-01 | daily_total_mileage_km | first=12345.6 | latest=12345.6 | sample_count=13
|
||
|
||
删除后等待真实流量窗口：
|
||
JT808 2026-07-01 metric rows = 0
|
||
```
|
||
|
||
清理原因：
|
||
|
||
- `LKLG7C4E3NA774736` 的 12345.6 来自此前生产连通性合成回放，不是真实平台上报。
|
||
- `LKLG7C4E2NA774775` 的 0 指标来自旧逻辑污染，当前 stat-writer 已跳过非正总里程。
|
||
|
||
Kafka spool：
|
||
|
||
```text
|
||
23:24 spool_count=904
|
||
23:25 spool_count=862
|
||
23:28 spool_count=722
|
||
new_spool_1min=0
|
||
```
|
||
|
||
说明：spool 正在回放下降，且最近 1 分钟没有新增文件；生产 gateway 日志未见 `Incorrect string value`、Kafka publish error 或 replay error。
