JT809协议

前提条件

掌握进制转换：二进制转十六进制；
掌握BCD编码、Hex编码；
掌握各种位移、异或；
掌握常用反射；
掌握JObject的用法；
掌握快速ctrl+c、ctrl+v；
掌握Span<T>的基本用法；
掌握以上装逼技能，就可以开始搬砖了。

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:

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;
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;
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;
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。

举个栗子1

1.组包：

业务数据类型 BusinessType:从链路报警信息交互消息

子业务类型标识 SubBusinessType:报警督办请求消息

JT809Package jT809Package = new JT809Package();

jT809Package.Header = new JT809Header
{
    MsgSN = 1666,
    EncryptKey = 9999,
    EncryptFlag= JT809Header_Encrypt.None,
    Version = new JT809Header_Version(1, 0, 0),
    BusinessType = JT809BusinessType.从链路报警信息交互消息.ToUInt16Value(),
    MsgGNSSCENTERID = 20180920,
};

JT809_0x9400 bodies = new JT809_0x9400
{
    VehicleNo="粤A12345",
    VehicleColor= JT809VehicleColorType.黄色,
    SubBusinessType= JT809SubBusinessType.报警督办请求消息.ToUInt16Value(),
};

JT809_0x9400_0x9401 jT809_0x9400_0x9401 = new JT809_0x9400_0x9401
{
    WarnSrc = JT809WarnSrc.车载终端,
    WarnType = JT809WarnType.疲劳驾驶报警.ToUInt16Value(),
    WarnTime = DateTime.Parse("2018-09-27 10:24:00"),
    SupervisionID = "123FFAA1",
    SupervisionEndTime = DateTime.Parse("2018-09-27 11:24:00"),
    SupervisionLevel = 3,
    Supervisor = "smallchi",
    SupervisorTel = "12345678901",
    SupervisorEmail = "123456@qq.com"
};

bodies.SubBodies = jT809_0x9400_0x9401;

jT809Package.Bodies = bodies;

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

string hex = data.ToHexString();

// 输出结果Hex：

2.手动解包：

1.原包：
5B 00 00 00 92 00 00 06 82 94 00 01 33 EF B8 01 00 00 00 00 00 27 0F D4 C1 41 31 32 33 34 35 00 00 00 00 00 00 00 00 00 00 00 00 00 02 94 01 00 00 00 5C 01 00 02 00 00 00 00 (5A 01) AC 3F 40 12 3F FA A1 00 00 00 00 (5A 01) AC 4D 50 03 73 6D 61 6C 6C 63 68 69 00 00 00 00 00 00 00 00 31 32 33 34 35 36 37 38 39 30 31 00 00 00 00 00 00 00 00 00 31 32 33 34 35 36 40 71 71 2E 63 6F 6D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 BA D8 5D

2.进行反转义
5A 01 ->5B
5A 02 ->5A
5E 01 ->5D
5E 02 ->5E
反转义后
5B 00 00 00 92 00 00 06 82 94 00 01 33 EF B8 01 00 00 00 00 00 27 0F D4 C1 41 31 32 33 34 35 00 00 00 00 00 00 00 00 00 00 00 00 00 02 94 01 00 00 00 5C 01 00 02 00 00 00 00 5B AC 3F 40 12 3F FA A1 00 00 00 00 5B AC 4D 50 03 73 6D 61 6C 6C 63 68 69 00 00 00 00 00 00 00 00 31 32 33 34 35 36 37 38 39 30 31 00 00 00 00 00 00 00 00 00 31 32 33 34 35 36 40 71 71 2E 63 6F 6D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 BA D8 5D
