Abstract

The invention discloses a massive and real-time tachograph data collection method. The method comprises the steps that a data collection server terminal receives the wireless connection emitted from bicycle tachograph terminal through a preset quantity of socket connection ponds; each complete data packet is decoded, the content, length and the concrete load of the message are analyzed; all types of tachograph data packets which have been received are transmitted to an upper layer application protocol to be processed; the application protocol sets different priority queries based on the data message types. Through the use of non-blocking data collection channel, and the reasonable processing of the collected data packets, the data collection capability of a single node server is tremendously elevated, and the data collection efficiency is elevated. Moreover through the data slicing and decoding, the data read-in and read-out frequency is reduced.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a method and system for collecting data from massive real-time driving recorders. Background technique [0002] The continuous increase of road vehicles and high travel pressure have created a strong demand for efficient and intelligent transportation. [0003] With the development of communication technology, cloud computing, and big data technology, the current field of intelligent transportation is facing many new application requirements, such as intelligent vehicle management and trajectory tracking, real-time road condition detection, adaptive traffic control, video surveillance and target recognition, traffic flow, etc. Forecasting and congestion analysis, etc. Governments and enterprises at all levels, driven by application requirements, are vigorously building intelligent transportation infrastructure, forming intelligent transportation management systems of var...
