Furthermore, in the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
Any process or method descriptions in flow charts or otherwise described herein may be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps of the process, and further implementations are included within the scope of the preferred embodiment of the present invention in which functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art of the present invention.
As shown in fig. 1, the invention provides a vehicle log management method, which comprises the following steps:
s1, configuring a unique identification code for a vehicle machine, and identifying the identity of the vehicle machine through the unique identification code by a cloud server;
s2, dividing each log into a plurality of compressed packets by the vehicle machine, and sequentially transmitting the compressed packets to the mobile terminal through Bluetooth by the vehicle machine and storing the compressed packets; the vehicle machine sends the unique identification code to the mobile terminal through Bluetooth and stores the unique identification code; the vehicle has a certain storage space, so that all the compressed packets are not required to be transmitted to the mobile terminal at one time, and all the compressed packets are not required to be transmitted to the mobile terminal. The intelligent device with Bluetooth transmission function such as an intelligent mobile phone and a tablet personal computer of the mobile terminal.
S3, the vehicle machine sends a log uploading request to the cloud server through the Internet, the log uploading request comprises a log date and a unique identification code, the cloud server screens out and extracts a corresponding compressed packet from the mobile terminal by using the log date and the unique identification code, and the vehicle machine sends the residual compressed packet to the cloud server;
s4, decompressing all the compressed packets by the cloud server, and extracting data in the compressed packets.
In order to further ensure the integrity of the data, the plurality of compression packets include a first compression packet, a second compression packet and a third compression packet, the first compression packet has log data and an operation formula, the second compression packet has log data and operation parameters, the third compression packet has log data and operation results, and the other compression packets have log data and operation data; the operation formula, the operation parameters, the operation data and the operation result can be determined according to the number of the compression packets, and for example, assuming that there are 5 compression packets, the operation formula can be aa+bb=c, where a=1, b=2, which are operation parameters, a=5, b=8, which are operation data, and c=21, which are operation results.
The cloud server decompresses all the compression packets, extracts an operation formula, operation parameters, operation data and operation results, substitutes the operation parameters and the operation data into the operation formula for calculation, compares the calculated results with the operation results, and judges whether the compression packets obtained by the cloud server are complete or not.
