Embodiment 1
[0050] see figure 1 , figure 1 It is a flowchart of a CAN (Controller Area Network, Controller Area Network) signal analysis method provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0051] Step S101, acquiring the CAN signal of the vehicle controller area network;
[0052] Specifically, the vehicle controller area network CAN signal is obtained through a USB (Universal Serial Bus, universal serial bus)-controller area network CAN adapter. The controller area network CAN signal includes addresses of all data frames.
[0053] Step S102, controlling the display screen to display the addresses of all the data frames;
[0054] Specifically, the display screen is controlled to display addresses of all data frames in a first preset area.
[0055] Step S103, obtaining the address of a certain data frame input by the user, and extracting data corresponding to the address of the certain data frame;
[0056] Specifically, the add...
Embodiment 2
[0066] see figure 2 , figure 2 It is a flow chart of another CAN signal analysis method provided by the embodiment of the present invention. Such as figure 2 As shown, the method includes:
[0067] Step S201, acquiring the vehicle controller area network CAN signal; the controller area network CAN signal includes addresses of all data frames;
[0068] Step S202, controlling the display screen to display the addresses of all the data frames;
[0069] Step S203, obtaining the address of a certain data frame input by the user, and extracting data corresponding to the address of the certain data frame;
[0070] Step S204, converting the data into a Boolean quantity, and controlling the display screen to display the Boolean quantity in the form of an indicator light; the number of the indicator lights is 64, corresponding to 64 bits of a data frame;
[0071] Step S205, obtaining several consecutive bits of data in the certain data frame input by the user, and converting the...
