Embodiment 1
[0038] Such as figure 1 As shown, it is a flow chart of a method based on CAN bus data storage in the embodiment of the present invention, which is described in detail as follows:
[0039] In step S101, collect CAN bus data;
[0040] Wherein, the way of collecting the CAN bus data is the collecting device 2, the collecting device 2 is connected to the CAN bus through the nodes, and when it is detected that the bus has data, it directly collects the CAN bus data.
[0041] In step S102, the CAN bus data is transmitted to the cache of the server 4 in the form of data packets, and a temporary table of the corresponding database 5 is generated;
[0042] Wherein, the CAN bus data is packaged into data packets, sent to the server 4 in the form of data packets, the server 4 and the acquisition device 2 can be connected through the mobile network 7, wired Ethernet, and USB network 8, and the server 4 receives the data package, a temporary table is generated in the database 5 for cach...
Embodiment 2
[0052] Such as figure 2 As shown, it is a network topology diagram based on CAN bus data storage in the embodiment of the present invention; the details are as follows:
[0053] Several acquisition devices 2 (as shown in A, B, and C, respectively represent acquisition devices with different numbers) transmit the CAN bus data collected to the server 4 through wired Ethernet, mobile network 7 and wired USB network 8 .
[0054] In the wired Ethernet network, the acquisition device 2 is connected to the switch 6 through a network cable, and the switch 6 is connected to the server 4 through a network cable to form a CAN bus data network. The server 4 polls the network IP of the collection device 2 sequentially to obtain the CAN bus data packets of the collection device 2. The collection device 2 can support a network transmission rate of 10 / 100Mb / s. During the test, it usually runs under normal power or idle mode, and the normal driving needs to be carried out on the drum bench. ...
Embodiment 3
[0060] Such as image 3 As shown, it is a system frame diagram based on CAN bus data storage in the embodiment of the present invention, and is described in detail as follows:
[0061] The collection device 2 is suitable for collecting CAN bus data;
[0062] The transmission unit 3 is adapted to transmit the CAN bus data to the cache of the server 4 in the form of data packets;
[0063] Wherein, the transmission methods of the transmission unit 3 include mobile network 7 , wired Ethernet, and USB network 8 , which will not be repeated here.
[0064] Server 4 is suitable for classifying the CAN bus data in the temporary table of the database 5 according to the collection device 2 names and the data source name to generate corresponding new data packets; the server 4 will The CAN bus data generates a corresponding new data packet, wherein the preset classification criteria include channel number, collection time, data length and CAN bus ID.
[0065] It is also suitable for ju...
