[0039] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0040] The CAN analyzer products on the market currently need manual setting of parameters before collecting data, the parameters are of many types and steps, the intelligent degree is not high, the users have certain technical requirements, the threshold is high, and the experience is poor. Moreover, if the parameters are set incorrectly or unreasonably, the product can not be normally used. Therefore, the embodiment of the present application discloses a bus data collection method, device, equipment and medium, which can collect bus data more intelligently to reduce manual participation.

[0041] Referring to Figure 1 The embodiment of the present application discloses a bus data collection method, which comprises:

[0042] Step S11: determining a target input-output channel with data.

[0043] In the embodiment, first of all, it needs to be pointed out that the bus data collection method disclosed by the present application can be applied to a CAN analyzer, that is, the CAN analyzer first determines which input-output channels (i.e., IO channels) have data, and takes them as target input-output channels.

[0044] Step S12: determining a target baud rate of the target input-output channel, so as to collect bus data from the target input-output channel at the target baud rate.

[0045] In the embodiment, after determining the target input-output channel with data, the baud rate of the target input-output channel is determined. It can be understood that the baud rate refers to the rate of data transmission in the communication channel, and the user can set the bus speed according to the specific needs of the CAN bus, that is, set the baud rate. Therefore, the embodiment of the present application needs to determine what the correct baud rate of a single target input-output channel is, so as to collect correct bus data therefrom, and then after determining the target baud rate, the CAN analyzer automatically collects bus data from the target input-output channel at the target baud rate, so as to realize intelligent collection of bus data. Moreover, the above process does not need manual setting of parameters, reduces the steps of manual operation, reduces the threshold of the user, and is convenient for ordinary users and maintenance technicians to use.

[0046] As can be seen, the present application determines a target input-output channel with data, determines a target baud rate of the target input-output channel, so as to collect bus data from the target input-output channel at the target baud rate. As can be seen, the present application first determines which input-output channels have data, and takes them as target input-output channels, and then determines the target baud rate of the target input-output channel, so as to automatically collect bus data from the target input-output channel at the target baud rate. Through the above technical solution, bus data can be collected more intelligently without manual setting of parameters.

[0047] Referring to Figure 2 and Figure 3 The embodiment of the application discloses a specific bus data acquisition method. Compared with the previous embodiment, the embodiment further describes and optimizes the technical solution. Specifically, it includes:

[0048] Step S21: All input and output channels are acquired, and whether there is a target signal in each input and output channel is monitored.

[0049] In this embodiment, first, a list of all possible input and output channels can be listed to acquire all input and output channels. The specific channel list can be 6-14, 3-11, 1-9, 2-10, 12-15, 12-13, 3-8, etc. Then, these input and output channels are traversed to monitor which channels have data. In the specific embodiment, whether the input and output channels have CAN protocol physical signals (ISO 11898 protocol standard) can be monitored.

[0050] Step S22: If there is, it is determined that there is data in the input and output channel, and the input and output channel is used as a target input and output channel.

[0051] In this embodiment, if there is a physical signal in the input and output channel, it can be determined that there is data in the input and output channel, and the input and output channel is used as a target input and output channel. In addition, the CAN analyzer can also name these target input and output channels with data, for example, CH1, CH2, CH3, etc., to facilitate subsequent data management and maintenance.

[0052] Step S23: All value information of the baud rate is acquired, and the baud rate priority in the value information is determined.

[0053] In this embodiment, first, all possible value information of the baud rate of the target input and output channel can be listed, for example: 5M, 2M, 1M, 500K, 250K, 125K, 100K, 75K, 50K, 25K, etc. The baud rate priority in the value information is determined. In general, the common 500K, 250K, 125K has a higher priority.

[0054] Step S24: The baud rates with different values are sequentially communicated with the target input and output channel according to the baud rate priority. If the bus data in the target input and output channel is acquired, the current baud rate is determined as the target baud rate of the target input and output channel.

[0055] In this embodiment, the different baud rates are sequentially communicated with the target input / output channel according to the baud rate priority, and if the bus data in the target input / output channel is acquired, the current baud rate is determined as the target baud rate of the target input / output channel, that is, the correct baud rate of the target input / output channel. For example, the baud rates of 500K, 250K and 125K are used to communicate with the channel, and if the data in the channel is acquired, it is indicated that the current baud rate is the correct target baud rate.

[0056] Step S25: determining a preset acquisition time under the target baud rate, and acquiring bus data from the target input / output channel within the acquisition time.

[0057] In this embodiment, the acquisition time is determined under the target baud rate, which can be controlled by itself or can be a default acquisition time, for example, 2 minutes. Then the bus data is acquired from the target input / output channel within the acquisition time.

[0058] Further, in the specific embodiment, the above-mentioned acquisition of bus data from the target input / output channel includes: determining a preset channel acquisition number, and simultaneously acquiring bus data from a corresponding number of target input / output channels based on the channel acquisition number. It can be understood that when acquiring bus data, data in a single input / output channel can be acquired at the same time, or data in multiple input / output channels can be acquired at the same time.

[0059] In addition, it should be noted that the above-mentioned process of acquiring bus data from the target input / output channel also includes: reading the vehicle identification code of the vehicle by using the target diagnostic software, so as to store the bus data based on the vehicle identification code. It can be understood that, as shown in Figure 4 The CAN analyzer in the embodiment of the application is integrated with vehicle model diagnosis, data acquisition and background management, so the vehicle identification code (i.e. VIN code) and other information of the vehicle can be read by using the standard OBD vehicle model diagnosis software when the bus data is acquired, so as to store the bus data based on the vehicle identification code, which is convenient for subsequent big data analysis and application. The vehicle identification code can be understood as the identity card number of the vehicle, which is determined according to the national vehicle management standard and contains information such as the production factory, brand, age, vehicle model, body type and code, engine code and assembly location of the vehicle. Therefore, when the bus data is stored, the corresponding vehicle identification code is also stored, which can improve the reusability of subsequent data and reduce the frequency of manual data acquisition on the vehicle, manpower and material resources. A single user can query and analyze big data according to the vehicle model, brand, year, VIN code and other information.

[0060] Step S26: encrypting the bus data, storing the encrypted bus data locally, and uploading the bus data to a background server under a preset condition.

[0061] In this embodiment, after the CAN analyzer collects data, the collected bus data is automatically saved in a local path, and is encrypted before being stored, so as to improve security. The user can export the bus data to a PC notebook or desktop through a diagnostic instrument and a U disk, and view or analyze the bus data through a tool. In addition, the bus data is uploaded to a background server for backup storage under a preset condition, so as to solve the problem that the collected bus data is stored locally and is easy to be lost. The preset condition can refer to a networked state, that is, the CAN analyzer automatically uploads the bus data to the background server for storage in the case of networking after collecting the bus data, so as to prevent the bus data from being lost. In this way, the user can view and analyze the bus data stored in the background server through a professional tool on other diagnostic instruments, notebook computers or desktop computers. Specifically, as shown in Figure 4 The CAN analyzer uploads the bus data to the background server for storage under the networking condition, so as to realize cloud backup.

[0062] It can be seen that in the embodiment of the application, whether there is data in the channel can be determined by monitoring whether there is a target signal in the input and output channel. When the target input and output channel is determined to have a correct baud rate, different values of the baud rate are sequentially communicated with the target input and output channel according to the baud rate priority. If data is obtained, the current baud rate is determined as the target baud rate of the target input and output channel, that is, the correct baud rate of the target input and output channel. When collecting bus data, the collection time of data and the number of channels that can be collected at the same time can be set, and the vehicle identification code and other information can be read by using diagnostic software, so as to store the bus data based on the vehicle identification code, and facilitate subsequent big data analysis and application. The CAN analyzer automatically saves the collected bus data in the local after encryption, and uploads the bus data to the background server for storage under the networking condition, so as to realize cloud backup and prevent data loss.
