Detailed Description
The preferred embodiments of the present application will be described in conjunction with the accompanying drawings, and it should be understood that they are presented herein only to illustrate and explain the present application and not to limit the present application.
Fig. 1 is a flowchart of a data processing method according to an embodiment of the present application, and as shown in fig. 1, the method can be implemented as the following steps S101 to S102:
in step S101, the vehicle bus data is read from a buffer queue for storing vehicle bus data, wherein the buffer queue is provided in a micro control unit;
the execution main body of the vehicle bus monitoring system can be an MCU (microprogrammed control unit) used for acquiring vehicle bus data in a domain control system, and the vehicle bus monitoring system acquires the vehicle bus data in real time in the vehicle operation process in order to monitor the operation state of a vehicle in real time. It can be understood that, because the priorities of the vehicle operation data are different, the vehicle bus data uploading can also be performed by setting different acquisition frequencies for different data according to the importance of the data.
Since the types of field buses are many, the vehicle bus data referred to in the present application is related to the types of field buses, and for example, when the field bus is a profibus (field bus control system), the vehicle bus data may be profibus data, and when the field bus is a CAN (Controller Area Network), the vehicle bus data may be CAN data. Since the CAN bus is the field bus which is most widely applied at present, the following technical scheme is introduced by taking the CAN bus as an example.
In step S102, the read vehicle bus data is sent to a system-on-chip, so that the system-on-chip uploads the vehicle bus data.
In order to ensure stable uploading of data, in the application, the data format of the vehicle bus data is converted into a data format capable of being transmitted through the serial peripheral interface; and sending the vehicle bus data after format conversion to the system-on-chip through the serial peripheral interface.
By adopting the scheme provided by the application, the buffer queue is additionally arranged in the MCU to store the vehicle bus data, so that the MCU replaces an external bus data collection module, the connection between the MCU and the SOC can be established without additionally arranging the module, and the vehicle bus data on the vehicle bus link can be collected due to the MCU, therefore, the communication burden of the vehicle bus link can not be additionally increased, and the reliability of the data is improved due to the reduction of communication nodes on the vehicle bus link. Secondly, because the SOC is not a real-time system, the frame loss phenomenon is easily caused by collecting data by an external module additionally arranged on the SOC, and the frame loss phenomenon can be effectively avoided by collecting and/or storing vehicle bus data through the MCU of the vehicle.
It should be noted that the SOC may upload vehicle bus data to a remote storage device, and the remote storage device generally refers to a cloud server, a hardware storage device, and the like corresponding to a vehicle management platform that can monitor, evaluate, and analyze a vehicle operating state through vehicle-mounted bus data, so as to ensure that the vehicle management platform can implement functions of monitoring, evaluating, and analyzing a vehicle operating state through the vehicle buses.
The beneficial effect of this application lies in: the vehicle bus data reading device has the advantages that the buffer queue for storing the vehicle bus is arranged in the micro control unit of the vehicle, so that the data storage function is realized, the read vehicle bus data can be sent to the system-on-chip after the vehicle bus data is read from the buffer queue for storing the vehicle bus data, the communication function with the system-on-chip is realized, the vehicle bus data can be uploaded by the system-on-chip, the vehicle bus data can be stored under the condition that a module is not additionally arranged, and the cost is saved.
In one embodiment, the step S102 may be further implemented as the following steps:
and sending the read vehicle bus data to a system-on-chip through a serial peripheral interface so that the system-on-chip uploads the vehicle bus data to an external storage device.
In this embodiment, in order to ensure stable uploading of data, the data format of the vehicle bus data is converted into a data format that can be transmitted through the serial peripheral interface; and transmitting the vehicle bus data after format conversion to the system-on-chip through the serial peripheral interface, and uploading the vehicle bus data to the outside by the system-on-chip.
In one embodiment, the method further comprises the following steps A1-A2:
in the step A1, vehicle bus data are obtained in the running process of a vehicle;
since the core communication systems in automobiles are all the CAN buses used, such as the communication between the engine, the transmission, the ECU, the steering and so on, in order to monitor the running state of the vehicle in real time, it is necessary to obtain the running data of the vehicle in real time, such as the engine start and stop time, the engine temperature, the engine speed, the throttle opening, the idle time, the engine continuous operation time, the battery voltage and so on. Therefore, in the present embodiment, the vehicle bus data is obtained during the operation of the vehicle, including but not limited to the starting, running, stopping, etc. of the vehicle.
In step A2, the change situation of the vehicle bus data is determined according to the acquired vehicle bus data.
In order to monitor and analyze the vehicle operating state, the present embodiment therefore determines the change of the vehicle bus data by analyzing the vehicle bus data. For example, when the vehicle is in normal driving, the data fed back by the steering lamp of the vehicle should be in an off state, and when the vehicle needs to turn, the data fed back by the steering lamp is changed from the off state to the on state, and then the data fed back by the steering lamp of the two times before and after the comparison can reflect the on state of the steering lamp through the change of the bus data of the vehicle. It can be understood that, because the stability of different vehicle data is inconsistent, for example, the steering angle of the steering wheel, and because the direction of the steering wheel is easily slightly changed on a bumpy road surface, the change range of the steering angle of the steering wheel can be set, when the change range is greater than a preset value, the data is considered to be changed, otherwise, the data is considered not to be changed; in addition, the method can be further subdivided in the case that the steering angle of the steering wheel is small, for example, when the steering is smaller than a preset value but the duration is longer than a preset time, the vehicle is still considered to be steering, and the data is considered to be changed.
Further, when the change condition of the vehicle bus data is that the vehicle bus data changes, the vehicle bus data is stored in the buffer queue; and when the vehicle bus data are not changed, reading the vehicle bus data from the buffer queue according to a second preset frequency. Furthermore, on one hand, real-time monitoring of data is guaranteed, and on the other hand, the situations of data redundancy and low system operation efficiency caused by a large amount of repeated data are avoided
The beneficial effect of this embodiment lies in: the vehicle bus data are monitored in the vehicle running state, and the change of the vehicle running state is obtained through the analysis of the change of the vehicle bus data.
In one embodiment, the above step S101 may be implemented as the following step B1:
in step B1, when the vehicle bus data changes, the changed vehicle bus data is read from the buffer queue.
In this embodiment, when the buffer queue for storing the vehicle bus data changes, it indicates that the vehicle operation data has changed, that is, there is a change in the operation state of a certain component of the vehicle, and therefore, the changed vehicle bus data is immediately read from the buffer queue for real-time uploading.
In one embodiment, the above steps of sending the read vehicle bus data to the system-on-chip through the serial peripheral interface may be implemented as the following steps C1-C2:
in step C1, converting the data format of the vehicle bus data into a data format that can be transmitted through the serial peripheral interface;
in step C2, the vehicle bus data after format conversion is sent to the system on chip through the serial peripheral interface.
In general, the format of the CAN bus data message is a frame format, and in the present application, the bus data format is transmitted through a serial peripheral interface, so that the CAN message needs to be converted into a data format capable of being transmitted through the serial peripheral interface, thereby ensuring smooth transmission of the CAN bus data.
Fig. 2 is a flowchart of a data processing method according to an embodiment of the present application, and as shown in fig. 2, the method can be implemented as the following steps S201 to S204:
in step S201, acquiring the vehicle bus data according to a first preset frequency;
in this step, the vehicle bus data is acquired according to a preset first preset frequency, wherein the vehicle bus data can be regarded as real-time acquisition when the frequency set by the first preset frequency is higher. Since the AUTOSAR (AUTOmotive Open System Architecture) running on the MCU has a Real-Time RTOS (Real Time Operation System), real-Time collection of CAN bus data CAN be ensured. It can be understood that, because the priorities of the vehicle operation data are different, different acquisition frequencies can be set for different data according to the importance of the data to upload the vehicle bus data.
In step S202, comparing the acquired vehicle bus data with the vehicle bus data acquired last time to determine a change condition of the vehicle bus data;
in this step, the change condition of the vehicle bus data is determined by comparing the acquired vehicle bus data with the vehicle bus data acquired at the previous time. For example, when the vehicle is in normal driving, the data fed back by the steering lamp of the vehicle should be in an off state, and when steering is needed, the data fed back by the steering lamp is converted from the off state to an on state, and then the data fed back by the steering lamp of the vehicle before and after the vehicle is compared, and the on condition of the steering lamp can be reflected through the change of the bus data of the vehicle. It can be understood that, because the stability of different vehicle data is inconsistent, for example, the steering angle of the steering wheel, and because the direction of the steering wheel is easily slightly changed on a bumpy road surface, the change range of the steering angle of the steering wheel can be set, when the change range is greater than a preset value, the data is considered to be changed, otherwise, the data is considered not to be changed; in addition, the method can be further subdivided in the case that the steering angle of the steering wheel is small, for example, when the steering is smaller than a preset value but the duration is longer than a preset time, the vehicle is still considered to be steering, and the data is considered to be changed.
In step S203, when the vehicle bus data changes, storing the changed vehicle bus data in the buffer queue;
in the step, the changed vehicle bus data is immediately stored, and when the data is not changed, the data does not need to be immediately stored, so that the conditions of data redundancy and low system operation efficiency caused by a large amount of repeated data are avoided.
In step S204, when the vehicle bus data is not changed, the vehicle bus data is read from the buffer queue according to a second preset frequency.
In this step, when the buffer queue for storing the vehicle bus data changes, it indicates that the vehicle operation data does not change, that is, the vehicle operation state does not change, so the preset frequency is maintained to read the vehicle bus data from the bus, so as to continuously monitor, record and analyze the vehicle operation condition.
The following describes a specific implementation manner of the present embodiment with reference to the accompanying drawings: fig. 3 is a block diagram of vehicle data transmission in this embodiment, as shown in fig. 3, because an AUTOmotive Open System Architecture (AUTOSAR) running on an MCU has a Real-Time RTOS (Real Time Operation System), so that Real-Time collection of CAN bus data CAN be ensured, in order to stably upload the bus data acquired in Real Time to an SOC, in this embodiment, a data link of an SPI (Serial Peripheral Interface) is used for data upload, and in order to ensure timeliness of data transmission, priority processing is performed on the data link, and a message of the CAN data is set to be a high priority. Fig. 4 is a flowchart of vehicle data transmission in this embodiment, as shown in fig. 4, in order to ensure that data is uploaded in time and resource waste caused by invalid transmission is avoided, the acquired CAN data is compared with the CAN data that is acquired last time, when the data changes, the CAN data that is acquired this time is placed in a buffer, and further, when the data is read and the vehicle bus data does not change, the vehicle bus data is read from the buffer queue according to a second preset frequency, that is, when the vehicle bus data does not change, the vehicle bus data needs to be read according to a certain frequency so as to periodically report the vehicle bus data to a remote storage device; when a buffer queue for storing vehicle bus data changes, the changed vehicle bus data is read from the buffer queue, namely when the vehicle bus changes, the vehicle bus data is read immediately, so that the changed vehicle bus data is reported to a remote storage device as soon as possible when the vehicle bus changes.
