To use the CAN interface data acquisition module to collect vehicle data, you can follow the steps below:
1) Hardware connection: connect the CAN interface data acquisition module to the CAN bus of the car. In general, the CAN bus of a car has two main channels, Can-High and Can-Low. Make sure that the CAN interface data acquisition module is properly connected to both channels.
2) Configure the CAN interface data acquisition module: Configure the CAN interface data acquisition module according to the specifications and requirements of the CAN interface data acquisition module. This includes setting the communication rate (baud rate), choosing the identifier and data length of the CAN message to be received, and other relevant parameters.
3) Data reception and parsing: Use the CAN interface data acquisition module to start receiving CAN messages on the CAN bus. The module receives information such as identifiers, data, and timestamps for CAN messages. Depending on your needs, you can choose to parse specific CAN messages to extract the required information, such as vehicle speed, engine speed, throttle position, etc.
4) Data storage and processing: The received CAN data can be stored in embedded memory or transferred to a computer or other equipment for further processing and analysis. You can use the appropriate software tools to process and interpret CAN data for data visualization, trend analysis, troubleshooting, and more.
5) Data application: According to your needs, CAN data can be applied to automotive performance evaluation, fault diagnosis, driving behavior analysis, etc. You can use visualization tools to present data, generate reports, or integrate into other systems.
