# 充电桩与网关 UDP JSON 通讯协议
|
||
|
||
## 概述
|
||
|
||
充电桩与网关之间通过 **以太网 UDP** 通信，使用 **JSON** 格式进行数据交换。
|
||
|
||
| 项目 | 说明 |
|
||
|------|------|
|
||
| 传输层 | UDP |
|
||
| 网关端口 | 6001 |
|
||
| 桩IP范围 | 10.12.19.101 ~ 106 |
|
||
| 数据格式 | JSON |
|
||
| 编码 | UTF-8 |
|
||
|
||
---
|
||
|
||
## 通讯流程
|
||
|
||
```
|
||
充电桩上电
|
||
↓
|
||
发送 online（上电） ──────→ 网关回复 charger_id
|
||
↓
|
||
正常运行时，每 5~10 秒
|
||
发送 heartbeat（心跳） ──→ 网关回复
|
||
↓
|
||
┌─── 网关下发 start charging（启动充电）
|
||
│
|
||
充电桩周期上报实时数据 ←──── 网关可下发 end charging（停止充电）
|
||
(realtime data / charge process real / bms info real)
|
||
│
|
||
└─── 充电结束 → 上报 settlement bill（结算账单）
|
||
```
