[智能网联汽车] CAN Log 文件 - ASC文件格式 [转]

news/2024/12/26 12:44:25/文章来源:https://www.cnblogs.com/johnnyzen/p/18305983

因工作研究需要，担心精华内容丢失。故全文转载，转载自：图文详解CAN Log文件 - ASC文件格式 - CSDN

Vector提供了两种记录数据格式的格式规范：BLF和ASC。
在Vector提供的CAN_LOG_TRIGGER_ASC_Format.pdf文件中，规定了CANoe/CANalyzer ASC记录中CAN、Log和Trigger event的格式。

1 CAN Log文件 -- ASC文件格式

1.1 Header

一个ASCII格式的日志文件以一个header开始。header包含关于日志文件的一般信息。

Format

date <WeekDay> <Month> <Date> <Fulltime> <Year>

base <hex |dec> timestamps <absolute |relative>

<”” |no> internal events logged

Example

date Wed Apr 16 09:21:13.159 am 2014

base hex timestamps absolute

internal events logged

base：表示记录的数值是hex十六进制或dec十进制的符号。

timestamps：表示时间戳是absolute绝对写入测量的开始时间还是relative相对于前一个事件。

internal：events logged表示是否记录了内部事件。

1.2 版本编号

从CANalyzer/CANoe v7.0开始，版本号以注释的形式写在Header之后：

Format Since v7.0	// version <major>.<minor>.<patch>
Example	// version 8.2.1

<major>.<minor>表示CANalyzer/CANoe的版本号

<patch>表示CANalyzer/CANoe主版本中的修改版本（如服务包中的修改）。

1.3 经典CAN网络中的描述

该部分列出了CANoe/CANalyzer ASC记录中的所有CAN event。

1.3.1 经典CAN Standard标准帧的描述

Format since v8.0	<Time> <Channel> <ID> <Dir> d <DLC> <D0> <D1>...<D8> Length = <MessageDuration> BitCount = <MessageLength> ID = <IDnum> <MessageFlags>
Example	0.003040 1 123 Tx d 2 00 00 Length = 768000 BitCount = 67 ID = 291

ID：表示 CAN ID 的十六进制值；

Length：表示发送/接收该Frame/Message占据总线的时间，单位纳秒；

BitCount：表示发送/接收该Frame/Message由多少各Bit构成；

IDnum：表示CAN ID的十进制值。

举例：

date Mon Apr 10 02:24:54.471 pm 2023
base hex  timestamps absolute
internal events logged
// version 11.0.00.036886 CAN 1 Status:chip status error active0.036886 CAN 2 Status:chip status error active0.101317 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 5290.201267 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 5290.301361 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 5290.401419 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 529

1.3.2 经典CAN Extended扩展帧的描述

Format since v8.0	<Time> <Channel> <ID>x <Dir> d <DLC> <D0> <D1>...<D8> Length = <MessageDuration> BitCount = <MessageLength> ID = <IDnum>x <MessageFlags>
Example	4.876870 1 54C5638x Tx d 8 00 00 00 00 00 00 00 00 Length = 1704000 BitCount = 145 ID = 88888888x

与经典CAN标准帧的差异: ID和IDnum后带字符x。

举例：

date Mon Apr 10 02:28:37.439 pm 2023
base hex  timestamps absolute
internal events logged
// version 11.0.00.021151 CAN 1 Status:chip status error active0.021151 CAN 2 Status:chip status error active0.101557 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x0.201483 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x0.301437 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x0.401151 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x

1.3.3 CAN Remote远程帧的描述

Format since v8.5	<Time> <Channel> <ID> <Dir> r <DLC> Length = <MessageDuration> BitCount = <MessageLength> ID = <IDnum>x
Example	2.5010 1 200 Tx r 8 Length = 1704000 BitCount = 145 ID = 88888888x

与经典CAN**标准 **/ 扩展帧的差异:没有<D0> <D1>...<D8>。

举例：

date Mon Apr 10 02:31:19.810 pm 2023
base hex  timestamps absolute
internal events logged
// version 11.0.00.041478 CAN 1 Status:chip status error active0.041478 CAN 2 Status:chip status error active0.101079 1  211             Tx   r 8  Length = 88015 BitCount = 47 ID = 5290.101219 1  211x            Tx   r 8  Length = 134015 BitCount = 70 ID = 529x0.200845 1  211x            Tx   r 8  Length = 134015 BitCount = 70 ID = 529x0.200939 1  211             Tx   r 8  Length = 88015 BitCount = 47 ID = 529

1.3.4 CAN Error错误帧的描述

CAN Error Frame
Format since v7.5	Interfaces with CAN-Core: <Time> <Channel> ErrorFrame Flags = <flags> CodeExt = <codeExt> Code = <code> ID = <ID> DLC = <DLC> Position = <Position> Length = <Length> Flags：定义参数Code, CodeExt, ID, DLC, Position和Length的有效性的Bit field。Bit含义： 0：SJA 1000 ECC是有效的 1：矢量CAN核心错误代码有效 2：矢量CAN核心错误位置有效 3：矢量CAN核心帧长度（ns）有效 Code： Vector CAN-Core的Bit含义： Bit 0-5： 0: Bit Error 1: Form Error 2: Stuff Error 3: Other Error 4: CRC Error 5: Ack-Del-Error 7: Ack-Error Bit 6-7： 0: RX-NAK-Error 1: TX-NAK-Error 2: RX-Error 3: TX-Error
	CodeExt：Extended error flags Bit 0-4：Segment (only SJA1000) Bit 5：Direction, 1=RX Bit 6-11：Error Code 0 Bit Error 1 Form Error 2 Stuff Error 3 Other Error 4 CRC Error 5 ACK- DEL Error 7 ACK Error Bit 12-13：Extended Direction 0 RX NAK 1 TX NAK 2 RX 3 TX Bit 14：1 =错误帧由应用程序发送备注 1 只对带有Vector CAN-Core的接口有效（CANcardXLe, VN7600, VN16xx, VN89xx和其他）。 2 ID、DLC和data field的有效性取决于干扰的类型和位置。例如：如果信息在ID- field受到干扰，那么只有ID的第一个Bit可能有效，但DLC和data field无效。错误位置不是干扰的位置。例如：如果错误位置位于CRC-field，那么信息可能在任何其他field受到干扰，错误的CRC是该干扰的结果。
Examples	1.592186 2 ErrorFrame Flags = 0xe CodeExt = 0x20a2 Code = 0x82 ID = 0 DLC = 0 Position = 5 Length = 11300

CAN Error Event

Format

<Time> CAN <Channel> Status:<Error>

<Time> CAN <Channel> Status:<Error> - TxErr: <TxCount> RxErr: <RxCount>

TxCount：

transmit error count寄存器的值

RxCount：

receive error count寄存器的值

Example

0.0006 CAN 2 Status:chip status error active

2137.317027 CAN 2 Status:chip status error active - TxErr: 8 RxErr: 0

2 小结：如何分辨CAN Log文件中的“标准帧”和“扩展帧”

2.1 经典CAN网络中的标准帧和扩展帧

经典CAN网络中的标准帧和扩展帧的差异:

经典CAN标准帧的ID和IDnum字段后不带字符x；
经典CAN扩展帧的ID和IDnum字段后带字符x。

举例：

date Mon Apr 10 04:24:18.233 pm 2023
base hex  timestamps absolute
internal events logged
// version 11.0.00.028996 CAN 1 Status:chip status error active0.028996 CAN 2 Status:chip status error active0.101449 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 5290.101745 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x0.201469 1  211x            Tx   d 8 00 00 00 00 00 00 00 00  Length = 290015 BitCount = 148 ID = 529x0.201717 1  211             Tx   d 8 00 00 00 00 00 00 00 00  Length = 242015 BitCount = 124 ID = 529

2.2 CANFD网络中的标准帧和扩展帧

CANFD网络中，可能同时存在：经典CAN标准帧，经典CAN扩展帧，CANFD标准帧，CANFD**扩展帧。

经典CAN/CANFD标准帧的ID字段后不带字符x；
经典CAN/CANFD扩展帧的ID字段后带字符x；
Flags字段的的Bit 12: FDF bit，其0表示经典CAN frame；1表示CAN FD frame。
