摘要
Abstract
First introduced the Beidou recorder composition and function ,timing 1 s and the timing 60 s transmit or storage were compared and analyzed the advantages and disadvan‐tages ,the paper according to the matching characteristics of the road gives a Markov chain based Beidou recorder data storage algorithm ,use node("knee point ")of Markov chain as the position point of recorder storage or transmission ,gathering information about the vehicle status and location module outputs information on the"knee"calculation algorithms for anal‐ysis and derivation ,and by numerous practical car tests ,tests show that :compared with the timing 1s to transmit or storage ,saving rate can reach more than 90% ,greatly saves storage space or communication cost ,has good use effect .关键词
