Description

Technical Field

[0001] This application relates to the field of vehicle network communication technology, and in particular to a method, system, device and medium for transmitting power distribution data. Background Technology

[0002] With the centralization of vehicle electronic and electrical architecture, the application of area controllers is becoming increasingly widespread. Area controllers have multiple power distribution pins, and power distribution data from these pins is frequently required in vehicle communication and controller status monitoring. Since a single area controller may have dozens of power distribution pins, the amount of power distribution data is large. However, each message can only transmit a maximum of 64 bits of data, necessitating the splitting of power distribution data from the same area controller into multiple messages. Existing methods typically assign a separate message ID to each message, resulting in the same area controller occupying multiple message IDs, increasing the complexity of network management and load scheduling. Furthermore, in existing methods, power distribution data often relies on the vehicle communication matrix for transmission. Adding or removing data requires modifying the vehicle communication matrix, and fault detection necessitates using complex mapping tables to convert message data into specific fault locations and types. This not only increases system resource consumption but also reduces the efficiency of fault detection and data maintenance. Summary of the Invention

By encoding power distribution data into strings and encapsulating them with message identifiers of area controllers, the power distribution pin data under the same controller can share message identifiers, thereby enhancing the synchronization and correlation of power distribution data, simplifying network management and improving the efficiency of fault detection and data maintenance.

[0007] Furthermore, before sorting the ASCII strings according to a preset sorting strategy to obtain the standard string, the process also includes: When the power distribution data of the first power distribution pin is abnormal, the highest bit of the character corresponding to the enumeration in the ASCII string corresponding to the power distribution data of the first power distribution pin is filled with 1, wherein the first power distribution pin is any one of multiple power distribution pins.

[0008] Furthermore, the standard string is encapsulated according to a message identifier pre-configured for the area controller to obtain multiple data packets, including: Obtain the message identifier of the area controller; The standard string is divided into multiple substrings based on the length of the data packet; Based on the message identifier of the area controller, multiple substrings are encapsulated to obtain multiple data packets.

[0009] Furthermore, before obtaining the message identifier of the area controller, the process also includes: Assign a unique message identifier to the area controller.

[0010] Furthermore, it also includes: Receive the data packet; The location and type of the fault are determined based on the data message. Based on the location and type of the fault, trigger the corresponding alarm or repair strategy.

[0014] In the embodiments of this application, the power distribution data of each power distribution pin of the vehicle area controller is first obtained; then, the power distribution data of each power distribution pin is encoded and sorted to obtain a standard string; then, according to the message identifier pre-configured for the area controller, the standard string is encapsulated to obtain multiple data packets, wherein each of the multiple data packets has the same message identifier; finally, the multiple data packets are sent sequentially.

Detailed Implementation

[0016] The present application will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the application. Furthermore, it should be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0017] It should be noted that, unless otherwise specified, the embodiments and features of the embodiments in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] The following describes in detail, with reference to the accompanying drawings, the method, system, device and medium for transmitting power distribution data according to embodiments of this application.

[0019] Figure 1 This is a flowchart of a power distribution data transmission method according to an embodiment of this application. Figure 1 As shown, a power distribution data transmission method according to an embodiment of this application is applied to a vehicle's area controller, the area controller having multiple power distribution pins, the method comprising the following steps: S101: Obtain the power distribution data of each power distribution pin.

[0020] In one embodiment of this application, the power distribution data of the power distribution pin includes: voltage, current, temperature, and fault status of the power distribution pin. This power distribution data is obtained in real time through area controller monitoring.

[0021] S102: Encode and sort the power distribution data of each power distribution pin to obtain a standard string.

[0022] In one embodiment of this application, the step of encoding and sorting the power distribution data of each power distribution pin to obtain a standard string includes: encoding the power distribution data of each power distribution pin into ASCII to obtain an ASCII string; and sorting each ASCII string according to a preset sorting strategy to obtain the standard string.

[0023] The following example shows the power distribution data for 10 power distribution pins. The values ​​in parentheses are the ASCII encoded results: J2-20:20A (0x4A 0x32 0x2D 0x32 0x30 0x3A 0x32 0x30 0x41 0x17) J2-10:100A (0x4A 0x32 0x2D 0x31 0x30 0x3A 0x31 0x30 0x30 0x41 0x17) J3-10:12V (0x4A 0x33 0x2D 0x31 0x30 0x3A 0x31 0x32 0x56 0x17) J3-5:24V (0x4A 0x33 0x2D 0x35 0x3A 0x32 0x34 0x56 0x17) J3-20:50°C (0x4A 0x33 0x2D 0x32 0x30 0x3A 0x35 0x30 0x6F 0x43 0x17) G1-13: Short ground fault (0x47 0x31 0x2D 0x31 0x33 0x3A 0x3D 0x30 0x3D 0x17) G4-10: Short circuit fault (0x47 0x34 0x2D 0x31 0x30 0x3A 0x3D 0x31 0x3D 0x17) G4-20: Temperature too high (0x47 0x34 0x2D 0x32 0x30 0x3A 0x3D 0x32 0x3D 0x17) G4-30: Temperature too low (0x47 0x34 0x2D 0x33 0x30 0x3A 0x3D 0x33 0x3D 0x17) G5-10:150°C (0x47 0x35 0x2D 0x31 0x30 0x3A 0x31 0x35 0x30 0x6F 0x430x17) Next, the converted ASCII strings are sorted using a preset sorting strategy. The sorting strategy can be set according to actual needs, for example, it can be sorted according to the fault occurrence time or priority detected by each power distribution pin.

[0024] In one embodiment of this application, before sorting each ASCII string according to a preset sorting strategy to obtain the standard string, the method further includes: when the power distribution data of the first power distribution pin is abnormal, filling the highest bit of the character corresponding to the enumeration in the ASCII string corresponding to the power distribution data of the first power distribution pin with 1, wherein the first power distribution pin is any one of a plurality of power distribution pins.

[0025] Specifically, the power distribution data of the power distribution pins contains fault information, including: short-to-ground fault, short-current fault, overheating, underheating, and over-temperature fault. In ASCII encoding, these five types of fault information are represented by numbers 0-4, separated from other data by equal signs. Specifically, it is represented as follows: 0: Short ground fault (0x3D 0x30 0x3D) 1: Short circuit fault (0x3D 0x31 0x3D) 2: Temperature too high (0x3D 0x32 0x3D) 3: Temperature too low (0x3D 0x33 0x3D) 4: Over-temperature fault (0x3D 0x34 0x3D) Furthermore, since the fault information variable is an enumeration, to distinguish it from the monitored value, the highest bit of the character corresponding to this fault information is filled with 1. Therefore, the ASCII encoding of the processed fault information is: 0: Short ground fault (0x3D 0xB0 0x3D) 1: Short circuit fault (0x3D 0xB1 0x3D) 2: Temperature too high (0x3D 0xB2 0x3D) 3: Temperature too low (0x3D 0xB3 0x3D) 4: Over-temperature fault (0x3D 0xB4 0x3D) S103: The standard string is encapsulated according to the message identifier pre-configured for the area controller to obtain multiple data packets, wherein each of the multiple data packets has the same message identifier.

[0026] In one embodiment of this application, the step of encapsulating the standard string according to the message identifier pre-configured for the area controller to obtain multiple data packets includes: obtaining the message identifier of the area controller; segmenting the standard string according to the length of the data packet to obtain multiple substrings; and encapsulating the multiple substrings according to the message identifier of the area controller to obtain multiple data packets.

[0027] Specifically, the first step is to set the length of the data packet. In a specific example, the length of the transmitted data packet is set to 64 bits, but it can be set to other lengths as needed. Next, based on the set data packet length, the standard string is split into multiple substrings of the same length. Then, these substrings are encapsulated using the area controller's message identifier to obtain multiple data packets. For example, assuming the area controller's message identifier is ID1, using a 64-bit message length for splitting results in the following data packets: ID1: 0x4A 0x32 0x2D 0x32 0x30 0x3A 0x32 0x30 ID1: 0x41 0x17 0x4A 0x32 0x2D 0x31 0x30 0x3A ID1: 0x31 0x30 0x30 0x41 0x17 0x4A 0x33 0x2D ID1: 0x31 0x30 0x3A 0x31 0x32 0x56 0x17 0x4A ID1: 0x33 0x2D 0x35 0x3A 0x32 0x34 0x56 0x17 ID1: 0x4A 0x33 0x2D 0x32 0x30 0x3A 0x35 0x30 ID1: 0x6F 0x43 0x17 0x47 0x31 0x2D 0x31 0x33 ID1: 0x3A 0x3D 0xB0 0x3D 0x17 0x47 0x31 0x2D ID1: 0x31 0x33 0x3A 0x3D 0xB1 0x3D 0x17 0x47 ID1: 0x34 0x2D 0x32 0x30 0x3A 0x3D 0xB2 0x3D ID1: 0x17 0x47 0x34 0x2D 0x33 0x30 0x3A 0x3D ID1: 0xB3 0x3D 0x17 0x47 0x35 0x2D 0x31 0x30 ID1: 0x3A 0x31 0x35 0x30 0x6F 0x43 0x17 0x4A ID1: 0x32 0x2D 0x32 0x30… … In one embodiment of this application, before obtaining the message identifier of the area controller, the method further includes: assigning a unique message identifier to the area controller.

[0028] In this way, the power distribution data of all power distribution pins under the same area controller have the same message identifier, thereby enhancing the synchronization and correlation of data, simplifying network management, and facilitating subsequent fault detection and data maintenance.

[0029] S104: Send multiple data packets in sequence.

[0030] To ensure reliable data reception and stable network load, a fixed period is used for message transmission. In a specific example, the message transmission period is set to 20ms, but other values ​​can be set according to actual needs.

[0031] In one embodiment of this application, the method further includes: receiving the data packet; determining the fault location and fault type based on the data packet; and triggering a corresponding alarm or repair strategy based on the fault location and fault type.

[0032] According to the power distribution data transmission method of the present invention, the power distribution data of each power distribution pin of the vehicle area controller is first acquired; then, the power distribution data of each power distribution pin is encoded and sorted to obtain a standard string; then, according to the message identifier pre-configured for the area controller, the standard string is encapsulated to obtain multiple data packets, wherein each of the multiple data packets has the same message identifier; finally, the multiple data packets are sent sequentially. Thus, by encoding the power distribution data into a string and encapsulating it using the message identifier of the area controller, the power distribution pin data under the same controller shares the message identifier, thereby enhancing the synchronization and correlation of power distribution data, simplifying network management, and improving the efficiency of fault detection and data maintenance.

Figure 2 As shown, a power distribution data transmission system according to an embodiment of this application is applied to a vehicle's area controller. The area controller has multiple power distribution pins. The system includes: an acquisition module 210, an encoding module 220, an encapsulation module 230, and a transmission module 240, wherein: The acquisition module 210 is used to acquire the power distribution data of each power distribution pin; The encoding module 220 is used to encode and sort the power distribution data of each power distribution pin to obtain a standard string; The encapsulation module 230 is used to encapsulate the standard string according to the message identifier pre-configured for the area controller to obtain multiple data packets, wherein each of the multiple data packets has the same message identifier; The transmission module 240 is used to sequentially send multiple data packets.

[0034] According to the power distribution data transmission system of this application embodiment, the power distribution data of each power distribution pin of the vehicle area controller is first obtained; then, the power distribution data of each power distribution pin is encoded and sorted to obtain a standard string; then, according to the message identifier pre-configured for the area controller, the standard string is encapsulated to obtain multiple data packets, wherein each of the multiple data packets has the same message identifier; finally, the multiple data packets are sent sequentially. Thus, by encoding the power distribution data into a string and encapsulating it using the message identifier of the area controller, the power distribution pin data under the same controller shares the message identifier, thereby enhancing the synchronization and correlation of the power distribution data, simplifying network management, and improving the efficiency of fault detection and data maintenance.
