Problems solved by technology

However, due to the large amount of driving data transmitted in real time, the bandwidth overhead of network transmission is increased, which is likely to cause network congestion and transmission delay, and to pay high communication fees (for data transmission). At the same time, the equipment side and platform side It is necessary to process the driving data transmitted in real time, and the calculation cost is large
[0003] Considering that for a single vehicle, there is a lot of compressed data that has nothing to do with collision detection, and these data have little reference value for collision analysis, that is, they do not need to be uploaded

Embodiment Construction

[0041] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0042] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0043] Such as figure 1 As shown, this embodiment discloses a method for calculating the timing of driving data packet compression, including the following steps:

[0044]S001: The data collection module collects driving data according to preset sampling rules, and obtains corresponding data packets for each sampling; stores the sampled data packets into the memory. Preferably, the collected data packets are stored in the memory in a cyclically rewritten manner, th...

Abstract

The invention discloses a method for calculating the compression timing of driving data packets and a data packet compression device. The method includes: the process of collecting data packets; the process of analyzing the speed and acceleration of the latest collected data packets; the process of determining valid data packets to be collected according to the analysis results; the screening process of data packets to be compressed; compressing the data packets the process of. The device includes: a sequentially connected data acquisition module, a memory, a data processing module, a control module and a data compression module, and the controller is also connected with a timer. The present invention can filter out a large number of invalid data packets by screening the data packets at the device end, greatly saving the amount of uploaded data packets, and saving the calculation overhead of the device end and the platform end. At the same time, the compressed data package describes the event completely and clearly. The data packet compression method can save network overhead and prevent packet loss.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a method for calculating the compression timing of driving data packets and a data packet compression device. Background technique [0002] In the context of the Internet of Things, the technology of collision detection using on-board equipment is slowly emerging in the industry. In the collision detection technology based on ordinary GNSS+g-sensor equipment, there is a technology that uses equipment to upload driving data to the platform in real time for collision detection. However, due to the large amount of driving data transmitted in real time, the bandwidth overhead of network transmission is increased, which is likely to cause network congestion and transmission delay, and to pay high communication fees (for data transmission). At the same time, the equipment side and platform side The driving data transmitted in real time needs to be processed, and the computational o...
