TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a fault information transmission method and device and storage medium. BACKGROUND

[0002] In a transmission system including an A-side device and a B-side device, if the A-side device fails, a processing unit of the B-side device needs to be notified, and the processing unit needs to determine the failure cause of the other device after receiving the notification information, and then perform corresponding processing.

[0003] When the transmission unit of the A-side device fails, the failure cause is recorded in the register in the transmission unit, and the B-side device judges the failure by reading the failure cause recorded in the register of the A-side device. However, due to the transmission mechanism limitation between the A-side device and the B-side device, the failure judgment efficiency of the B-side device is reduced. SUMMARY

[0004] Therefore, a fault information transmission method, device and storage medium are provided to improve the failure judgment efficiency of the second device.

[0005] In a first aspect, an embodiment of the present application provides a fault information transmission method for a transmission system including a first device and a second device, the method comprising:

[0006] When a first transmission unit of the first device fails, the first device sends fault information to the second device, and the fault information is used to indicate a first failure cause of the first transmission unit;

[0007] A second transmission unit of the second device receives the fault information, stores the fault information in a storage space of the second transmission unit, and sends a notification signal to a processing unit of the second device;

[0008] The processing unit receives the notification signal and reads the fault information in the storage space of the second transmission unit.

[0009] In this implementation, the first device sends fault information indicating the first failure cause of the first transmission unit to the second device, and the second transmission unit of the second device receives the fault information and stores it in the local storage space, and sends a notification signal to the processing unit of the second device. The processing unit can directly obtain the fault information by reading the local storage space, avoiding the situation that the failure judgment efficiency is low due to the transmission mechanism limitation between the two devices of the transmission system in the related art, greatly shortening the time length of the processing unit obtaining the current first failure cause of the first transmission unit, and improving the failure judgment efficiency of the second device.

[0010] In a possible implementation, the fault information includes a first index value, and the method further includes:

[0011] The first device determines the first index value corresponding to the first fault cause according to a preset correspondence relationship, and the preset correspondence relationship includes a one-to-one correspondence relationship between fault causes and index values.

[0012] The processing unit receives the notification signal and reads the fault information in the storage space of the second transmission unit, and further includes:

[0013] The processing unit determines the first fault cause corresponding to the first index value according to the preset correspondence relationship.

[0014] In this implementation, the first device sends the first index value corresponding to the first fault cause to the second device, so that the second transmission unit of the second device stores the received first index value in the local storage space and sends a notification signal to the processing unit, so that after the processing unit reads the first index value in the storage space of the second transmission unit, the first fault cause corresponding to the first index value is directly determined according to the preset correspondence relationship, and the efficiency of the processing unit in acquiring the current first fault cause of the first transmission unit is further ensured.

[0104] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

"And / or" can be used to describe three relationships between related objects. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. A and B can be singular or plural. To facilitate the description of the technical solutions in this application embodiment, the terms "first" and "second" can be used to distinguish technical features with the same or similar functions. These terms do not limit the quantity or execution order, and they are not necessarily different.

Any embodiment or design described as "exemplary" or "for example" should not be construed as being better or more advantageous than other embodiments or design solutions. The use of "exemplary" or "for example" is intended to present related concepts in a specific manner for ease of understanding.

[0106] In the embodiments of this application, for a technical feature, the technical features in the technical feature are distinguished by "first", "second", "third", "A", "B", "C" and "D", and there is no order of priority or size among the technical features described by "first", "second", "third", "A", "B", "C" and "D".

[0107] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0108] In related technologies, taking an in-vehicle image transmission system as an example, with a camera as the A-end device and a computing platform as the B-end device, in a schematic example, the computing platform can be a mobile data center (MDC), such as... Figure 1 As shown, camera 100 is used to capture images during driving, and mobile data center 120 is used to process the data collected by the camera, such as performing image processing and analyzing the vehicle's surrounding environment. Camera 100 includes a sensor 102 and a serializer 104 connected to the sensor 102. Mobile data center 120 includes a deserializer 122 and a processing chip 124 connected to the deserializer 122. Data transmission between the serializer 104 of camera 100 and the deserializer 122 of mobile data center 120 is performed. During operation, the serializer 104 of camera 100 may experience various malfunctions. When the serializer 104 of camera 100 malfunctions, camera 100 sends an interrupt signal to the deserializer 122 of mobile data center 120 through the serializer 104. Upon receiving the interrupt signal, deserializer 122 generates a pulse signal on its general-purpose input / output (GPIO) interface. This pulse signal is used to notify processing chip 124 that a malfunction has occurred. Upon receiving the pulse signal, the processing chip 124 initiates a diagnostic process on the Inter-Integrated Circuit (I2C) bus. 2 C) The serializer 104 of the camera 100 is read from the interface by the deserializer 122 to obtain the cause of the fault.

[0109] However, in the above method, due to I 2 The C interface operates by requiring a 1-bit feedback message to be sent for every 8 bits of data transmitted. This results in very low data transmission efficiency between the deserializer 122 and the serializer 104, which in turn makes it very slow for the processing chip 124 to read the registers in the serializer 104. Consequently, the time required to determine the cause of the fault is longer, and the fault diagnosis efficiency of the mobile data center 120 is low.

[0110] To address this, this application provides a fault information transmission method, apparatus, and storage medium. A first device sends fault information indicating a first fault cause for a first transmission unit failure to a second device. Upon receiving the fault information, the second transmission unit of the second device stores the fault information in its local storage space and sends a notification signal to the processing unit of the second device. The processing unit can directly obtain the fault information by reading the local storage space, avoiding the situation in related technologies where the transmission mechanism between the two ends of the transmission system results in low fault judgment efficiency. This significantly shortens the time for the processing unit to obtain the current first fault cause of the first transmission unit and improves the fault judgment efficiency of the second device.

[0111] First, the application scenarios involved in this application are introduced. The fault information transmission method provided in the embodiments of this application is applied to a transmission system including a first device and a second device, which can be a vehicle.

Illustratively, the first interface is a GPIO interface, and the second interface is an I... 2 C interface.

[0115] In this embodiment of the application, the first device 210 is used to send fault information to the second device 220 when the first transmission unit 212 fails. The fault information is used to indicate the first fault cause of the failure of the first transmission unit 212.

The processing unit 224 is used to receive the notification signal and read the fault information in the storage space of the second transmission unit 222.

[0128] Optionally, the display 410 is used to display images, videos, etc. The display 410 includes a display panel. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a miniature LED, a microLED, a quantum dot light-emitting diode (QLED), etc.

[0129] Optionally, the cockpit controller 420 is used to control the vehicle's interior seats and display 410. Illustratively, the cockpit controller 420 is connected to both the in-vehicle equipment and the display 410 via a high-speed communication bus.

[0130] In this embodiment, the display 410 is used to send fault information to the cockpit controller 420 when the deserializer 412 malfunctions. The fault information is used to indicate the first cause of the malfunction of the deserializer 412. The serializer 422 of the cockpit controller 420 is used to receive the fault information, store the fault information in the storage space of the serializer 422, and send a notification signal to the processing chip 424 of the cockpit controller 420. The processing chip 424 is used to receive the notification signal and read the fault information in the register of the serializer 422.

[0131] It should be noted that the application scenarios of the fault information transmission method in this application embodiment are not limited.

[0132] The following describes the fault information transmission method provided in the embodiments of this application using several exemplary models.

[0133] Please refer to Figure 5It illustrates a flowchart of a fault information transmission method provided in an exemplary embodiment of this application. This embodiment uses this method for... Figures 2 to 4 Let's take any of the transmission systems shown as examples. The method includes the following steps.

[0134] Step 501: When the first transmission unit of the first device fails, the first device sends fault information to the second device. The fault information is used to indicate the first fault cause of the failure of the first transmission unit.

[0135] Optionally, the first device detects whether the first transmission unit has malfunctioned in real time or at preset time intervals. If a malfunction is detected in the first transmission unit of the first device, the first device sends a malfunction message to the second device.

[0136] The preset time interval can be a custom setting or a default setting. This application does not limit this.

[0137] Optionally, if a fault is detected in the first transmission unit of the first device, the first device stores the fault information in the storage space of the first transmission unit.

[0138] Optionally, during a period of time when the first transmission unit of the first device malfunctions, the first device sends fault information to the second device. That is, at the start time of the first transmission unit malfunction or at a target time after the start time, the first device sends fault information to the second device, wherein the absolute value of the difference between the target time and the start time is less than a preset time threshold.

[0139] In this process, the first device and the second device transmit data through their respective transmission units, that is, the first transmission unit of the first device sends fault information to the second transmission unit of the second device.

[0140] Optionally, the fault information includes a first index value, which is the number of the first fault cause in which the first transmission unit fails, and is used to indicate the first fault cause.

[0141] Optionally, the first transmission unit of the first device stores a preset correspondence, which includes a one-to-one correspondence between fault causes and index values. Illustratively, the fault causes include at least one of a single-bit fault in memory, a multi-bit fault in memory, and an internal bus transmission fault. Here, the memory refers to the internal storage of the first transmission unit of the first device.

[0142] For example, the preset correspondence includes: index value "0x1" corresponds to the fault cause "single bit fault in memory", index value "0x2" corresponds to the fault cause "multiple bit fault in memory", index value "0x3" corresponds to the fault cause "internal bus transmission fault", index value "0x4" corresponds to the fault cause "unstable power supply voltage of processing chip", index value "0x5" corresponds to the fault cause "link lockout", index value "0x6" corresponds to the fault cause "Cyclic Redundancy Check (CRC) error", and index value "0x7" corresponds to the fault cause "buffer overflow in processing chip". This application embodiment does not limit this.

[0143] Optionally, when the first transmission unit of the first device fails, the first device sends fault information to the second device, including: when the first transmission unit of the first device fails, the first device determines the first fault cause of the first transmission unit failure, the first device determines the first index value corresponding to the first fault cause according to a preset correspondence, and the first device sends the first index value to the second device.

[0144] In one possible implementation, when a fault occurs in the first transmission unit of the first device and the priority of the fault cause is greater than a preset priority threshold, the first device sends fault information to the second device. That is, in this implementation, the priority of the first fault cause indicated by the fault information is greater than the preset priority threshold.

[0145] Optionally, when the first transmission unit of the first device fails and the priority of the fault cause is less than or equal to a preset priority threshold, the first device does not send fault information to the second device, and the second device reads the current fault information of the first device in accordance with the methods provided in related technologies.

[0146] Optionally, multiple priorities for different fault causes can be pre-set. One possible setting is to set the priority of the target fault cause as the first priority, and the priorities of other fault causes besides the target fault cause as the second priority, wherein the target fault cause includes at least one fault cause. The first priority is greater than a preset priority threshold, and the second priority is less than the preset priority threshold.

[0147] For example, multiple fault causes include single-bit faults in memory, multi-bit faults in memory, and internal bus transmission faults. Among them, faults caused by "multi-bit faults in memory" and "internal bus transmission faults" will affect the function and require the intervention of the processing unit of the second device when an error occurs. The priority of these two fault causes can be set to the first priority, i.e., high priority. Faults caused by "single-bit faults in memory" can be automatically corrected. When an error occurs, only a warning is needed and no intervention of the processing unit of the second device is required. The priority of this fault cause can be set to the second priority, i.e., low priority.

[0148] Another possible configuration is to set the priority of the first target fault cause as the first priority, the priority of the second target fault cause as the second priority, and the priority of all other fault causes besides the first and second target fault causes as the third priority. Both the first and second target fault causes include at least one fault cause. The first and second priorities are greater than a preset priority threshold, while the third priority is less than the preset priority threshold.

[0149] It should be noted that the embodiments of this application do not limit the method of setting the priority of fault causes.

[0150] Step 502: The second transmission unit of the second device receives the fault information, stores the fault information in the storage space of the second transmission unit, and sends a notification signal to the processing unit of the second device.

[0151] The second transmission unit of the second device receives fault information sent by the first transmission unit. After receiving the fault information, the second transmission unit stores the fault information in its own storage space and sends a notification signal to the processing unit. It should be noted that the steps of the second transmission unit storing the fault information in its own storage space and the steps of the second transmission unit sending a notification signal to the processing unit can be performed simultaneously or sequentially. This application embodiment does not limit this.

[0152] The storage space of the second transmission unit is a register. Optionally, the second transmission unit includes multiple registers, and the storage space for storing fault information is a designated register among the multiple registers.

[0153] Optionally, the fault information includes a first index value, which indicates the first cause of the fault in the first transmission unit. That is, the second transmission unit of the second device receives the first index value and stores it in the storage space of the second transmission unit.

[0154] Optionally, the second transmission unit generates a pulse signal, or notification signal, on the first interface. This notification signal indicates a fault in the first transmission unit of the first device. The second transmission unit sends this notification signal to the processing unit through the first interface. Illustratively, the first interface is a GPIO interface.

[0155] In one possible implementation, the first device only sends a first index value to the second device and does not send an interrupt signal. The interrupt signal is used to indicate that the first transmission unit of the first device has failed. That is, when the first transmission unit of the first device fails, the first device sends the first index value to the second device; the second transmission unit of the second device receives the first index value, stores the first index value in the storage space of the second transmission unit, and sends a notification signal to the processing unit of the second device.

[0156] Optionally, the second transmission unit generates a notification signal based on the first index value and sends the notification signal to the processing unit of the second device. The generation of the notification signal by the second transmission unit based on the first index value includes: the second transmission unit generating the notification signal upon determining that it has received the first index value, the notification signal being used to instruct the processing unit to read the first index value from the storage space of the second transmission unit.

[0157] In another possible implementation, the first device sends an interrupt signal and a first index value to the second device. That is, when the first transmission unit of the first device malfunctions, the first device sends an interrupt signal and a first index value to the second device. The second transmission unit of the second device receives the interrupt signal and the first index value, stores the first index value in its storage space, and sends a notification signal to the processing unit of the second device.

[0158] The interrupt signal and the first index value can be sent simultaneously or separately. Specifically, when the first transmission unit of the first device fails, the first device sends both the interrupt signal and the first index value to the second device simultaneously; or, when the first transmission unit of the first device fails, the first device sends the interrupt signal to the second device and then sends the first index value; or, when the first transmission unit of the first device fails, the first device sends the first index value to the second device and then sends the interrupt signal. This application does not limit this specific approach.

[0159] Optionally, the interrupt signal is a digital signal, and the interrupt signal is represented by at least one bit of information, wherein the at least one bit of information can be a default setting or a custom setting. For example, the interrupt signal is a custom-set 8-bit information "01010101". This application embodiment does not limit this.

[0160] Optionally, the second transmission unit generates a notification signal based on the interrupt signal and the first index value, and sends the notification signal to the processing unit of the second device. Specifically, the second transmission unit generates the notification signal based on the interrupt signal and the first index value by: the second transmission unit generating the notification signal upon determining that it has received the interrupt signal and the first index value, the notification signal being used to instruct the processing unit to read the first index value from the storage space of the second transmission unit.

[0161] Step 503: The processing unit receives a notification signal and reads the fault information from the storage space of the second transmission unit.

[0162] The processing unit receives a notification signal sent by the second transmission unit. After receiving the notification signal, the processing unit reads the fault information from the storage space of the second transmission unit.

[0163] Optionally, the processing unit reads fault information from the storage space of the second transmission unit via the second interface. Illustratively, the second interface is I... 2 C interface.

[0164] Optionally, the fault information includes a first index value, and the processing unit of the second device stores a preset correspondence, which includes a one-to-one correspondence between fault causes and index values. After reading the first index value, the processing unit of the second device determines the first fault cause corresponding to the first index value according to the preset correspondence. It should be noted that the description of the index value and fault cause can be found in the relevant descriptions in the above steps, and will not be repeated here.

[0165] In summary, the embodiments of this application transmit fault information indicating a first fault cause for a first transmission unit failure to a second device via a first device. After receiving the fault information, the second transmission unit of the second device stores the fault information in its local storage space and sends a notification signal to the processing unit of the second device. The processing unit can directly obtain the fault information by reading the local storage space, avoiding the situation in related technologies where the fault judgment efficiency is low due to the limitations of the transmission mechanism between the two devices of the transmission system. This greatly shortens the time for the processing unit to obtain the current first fault cause of the first transmission unit and improves the fault judgment efficiency of the second device.

[0166] This application embodiment also allows the first device to send only a first index value to the second device when the first transmission unit of the first device fails, without sending an interrupt signal. The first index value is used to indicate the first fault cause of the first transmission unit failure. This enables the second transmission unit of the second device to store the first index value in its storage space and send a notification signal to the processing unit after receiving the first index value. This improves the efficiency of obtaining the fault cause and further saves the data transmission overhead between the first device and the second device.

[0167] This application embodiment also improves the efficiency of fault cause acquisition while further ensuring the reliability of notification signal transmission. When the first transmission unit of the first device fails, the first device sends an interrupt signal and a first index value to the second device. The interrupt signal indicates that the first transmission unit of the first device has failed, and the first index value indicates the first fault cause of the first transmission unit failure. This allows the second transmission unit of the second device to store the received first index value in its storage space and triggers the generation and transmission of a notification signal based on the received interrupt signal and first index value.

[0168] Furthermore, in related technologies, the serializer 104 is equipped with multiple registers to record various fault causes. When the processing chip 124 detects a fault in the camera 100, it then uses I... 2 When the C interface reads the current fault cause, it uses a register lookup method to obtain the fault cause. This can result in a long time to look up the fault cause. For example, if the fault cause is recorded in the last register, the processing chip 124 must look up the last register to obtain the current fault cause.

[0169] In this embodiment, a target storage space is set in the first transmission unit of the first device. The target storage space is one of multiple storage spaces and is used to store the first fault cause of the first transmission unit failure. This allows the processing unit of the second device to prioritize reading the data in the target storage space of the first transmission unit when it needs to read the first fault cause of the first transmission unit, thereby shortening the time required to query the current first fault cause of the first transmission unit.

[0170] In one possible implementation, please refer to Figure 6 It illustrates a flowchart of a fault information transmission method provided in another exemplary embodiment of this application, which is used in this embodiment for... Figures 2 to 4 Let's take any of the transmission systems shown as examples. The method includes the following steps.

[0171] Step 601: When the first transmission unit of the first device fails, the first device sends an interruption message to the second device.

[0172] Optionally, the interrupt information includes the interrupt signal and the identifier of the target memory space.

[0173] The interrupt signal is used to indicate a fault in the first transmission unit of the first device. The identifier for the target memory space can be the name or address of the target memory space. For example, the target memory space could be the target register.

[0174] Optionally, the interrupt information includes an interrupt signal. The identifier of the target storage space is pre-agreed upon by the first device and the second device.

[0175] Step 602: The second transmission unit of the second device receives the interrupt information and sends a notification signal to the processing unit of the second device.

[0176] The second transmission unit of the second device receives the interruption information and sends a notification signal to the processing unit of the second device. The notification signal is used to indicate that the first transmission unit of the first device has failed.

[0177] Step 603: The processing unit receives the notification signal and reads the first fault cause from the target register of the first transmission unit through the second transmission unit.

[0178] The target storage space is used to store the first cause of failure when the first transmission unit fails.

[0179] Optionally, the first fault cause is a fault cause with a priority greater than a preset priority threshold. This allows the processing unit of the second device to prioritize reading data from the target storage space of the first transmission unit when it needs to read the first fault cause of the first transmission unit, thereby shortening the time required to query high-priority fault causes.
