JT809数据结构解析

数据包[JT809Package]

头标识 数据头 数据体 CRC校验码 尾标识
BeginFlag JT809Header JT809Bodies CRCCode EndFlag
5B - - - 5D

数据头[JT809Header]

数据长度 报文序列号 业务数据类型 下级平台接入码 协议版本号标识 报文加密标识位 数据加密的密匙 发送消息的系统时间(2019版本)
MsgLength MsgSN BusinessType MsgGNSSCENTERID Version EncryptFlag EncryptKey Time

数据体[JT809Bodies]

根据对应业务数据类型：BusinessType

车牌号 车辆颜色 子业务类型标识 后续数据长度 子业务数据体
VehicleNo VehicleColor SubBusinessType DataLength JT809SubBodies

子数据体[JT809SubBodies]

根据对应子业务数据类型 SubBusinessType 处理子业务数据体(JT809SubBodies)。

注意：数据内容(除去头和尾标识)进行转义判断

转义规则如下:

  1. 若数据内容中有出现字符 0x5b 的，需替换为字符 0x5a 紧跟字符 0x01;
  2. 若数据内容中有出现字符 0x5a 的，需替换为字符 0x5a 紧跟字符 0x02;
  3. 若数据内容中有出现字符 0x5d 的，需替换为字符 0x5e 紧跟字符 0x01;
  4. 若数据内容中有出现字符 0x5e 的，需替换为字符 0x5e 紧跟字符 0x02.

反转义的原因：确认JT809协议的TCP消息边界。

1.组包：

bodies.SubBodies = jT809_0x9400_0x9401;

jT809Package.Bodies = bodies;

byte[] data = JT809Serializer.Serialize(jT809Package);

string hex = data.ToHexString();

2.手动解包：

反转义后
