Abstract

The invention discloses a packet compressing and storing method and device. The method comprises the steps of receiving original packet data; acquiring each timestamp in the original packet data, andcalculating variation of each time period according to each timestamp, wherein a first timestamp is reference time of an original packet; acquiring each packet data segment in the original packet data, using a first packet data segment of all the packet data segments as a reference packet data segment, and calculating variation of each packet data segment according to each packet data segment; andrecording block header information of the original packet data, the reference time of the original packet data, the variation of each time segment, basic packet data segment and variation of each packet data segment except the first packet data segment. Compared with existing storing method, the method provided in the invention saves storage space and improves storage efficiency.

Description

technical field [0001] The invention relates to the field of vehicle bus technology, in particular to a message compression storage method and device. Background technique [0002] With the rapid development of the automobile industry, the CAN bus is used as a communication bus between various parts of the car to realize data transmission between various parts. In order to monitor and predict the status of various components, the collected CAN messages on the CAN bus need to be stored when the vehicle is running. [0003] In the existing message storage method, the collected CAN messages are stored according to the bus or according to the CAN ID, and the basic storage format is: time stamp+ID+message content. [0004] The inventor found in the research process of the prior art that although the existing storage methods can completely store the messages on the CAN bus, because the acquisition of the messages is periodic acquisition, such as collecting CAN data every 1 second...
