The invention discloses a locomotive brake, a data memory, a data verification method and a rail transit vehicle. The data memory is divided into N independent sectors; and reading the data in each sector to obtain N pieces of data, and when the number of the same data in the N pieces of data exceeds (N-1)/2, judging the same data as correct data, and judging the other data as wrong data. According to the method, the problems of data storage errors, data reading errors and the like which easily exist during data storage are solved, the error probability during state storage and reading of the brake is effectively reduced, and the safety and usability of the brake are improved.

    本发明公开了一种机车制动机、数据存储器及数据校验方法、轨道交通车辆,将数据存储器划分为N个独立的扇区;读取每个扇区中的数据,获得N个数据,当该N个数据中相同数据的个数超过(N‑1)/2个时,将该相同数据判定为正确数据,其余数据判定为错误数据。本发明解决了数据存储时容易存在的数据存储错误、数据读取错误等问题,有效降低了制动机状态存储及读取时的错误概率,提高了制动机的安全性和可用性。
