    Distributed locomotive positioning method and device based on information consensus

    Freier Zugriff

    The invention discloses a distributed locomotive positioning method and device based on information consensus. The technical problem of large error of a traditional locomotive positioning method can be solved. The method comprises the following steps: acquiring a position coordinate of a current vehicle head as a first estimated value M1 of a vehicle head position; acquiring the position coordinates of current N railway carriages, and taking vehicle head positions corresponding to the position coordinates of the current N railway carriages as N second estimated values M2 of the vehicle head positions; performing consensus on the first estimated value M1 and the N second estimated values M2 to obtain N deviation quantities of M1 deviating from M2; and judging whether M deviation values in the N deviation values are equal to a preset deviation value or not, if so, uploading the M1 to a server, and if not, abandoning the M1, and repeatedly obtaining a next to-be-uploaded first estimated value M1, wherein M is greater than or equal to N/2 and less than or equal to N. The accurate position information of the locomotive head is acquired by adopting a distributed information consensus mode, so that the communication traffic and the communication distance can be effectively reduced, and the transmission efficiency is improved.

    本发明公开了一种基于信息共识的分布式机车定位方法及装置，可解决传统机车定位的方法误差较大的技术问题。包括以下步骤获取当前车头的位置坐标，作为车头位置的第一估算值M1；获取当前N个车皮的位置坐标，并将当前N个车皮的位置坐标对应的车头位置作为车头位置的N个第二估算值M2；将第一估算值M1与N个第二估算值M2进行共识，得到M1偏离M2的N个偏离量；判断N个偏离量中的M个偏离量是否等于预设偏差值，若是，则将M1上传到服务器，若否，则将M1舍弃，重复获取下一个待上传的第一估算值M1，M大于等于N/2、且小于等于N。采用本发明分布式的信息共识方式来获取准确的机车车头的位置信息，能够有效的减少通信量和通信距离，提高传输效率。
