The invention discloses a multi-core heterogeneous polling hybrid four-wheel wheel speed signal acquisition device and an acquisition method. The multi-core heterogeneous polling hybrid four-wheel wheel speed signal acquisition device comprises a data acquisition module, a data processing module and a data storage module, wherein the data acquisition module is configured to perform parallel acquisition on wheel speed signals of four wheels; the data storage module is configured to store the wheel speed signals acquired by the data acquisition module, and each piece of wheel speed data corresponds to at least two wheel speed cache units; the data processing module is configured to poll and read the wheel speed data stored in the data storage module and perform serial processing; wherein the data acquisition module and the data processing module respectively process different wheel speed cache units of the same wheel speed data at the same time, so that the delay and blockage risks caused by simultaneous reading of multiple paths of data are avoided; and the switching work of an existing data acquisition system in the acquisition and storage process of multiple paths of signals is eliminated, so that the data acquisition efficiency, the data acquisition precision and the data acquisition reliability are greatly improved.
本发明公开了一种多核异构轮询混合式四轮轮速信号采集设备及采集方法,其包括数据采集模块、数据处理模块以及数据存储模块;其中,数据采集模块配置为对四轮的轮速信号进行并行采集;数据存储模块配置为对数据采集模块采集的轮速信号进行存储,且每一个轮速数据对应至少两个轮速缓存单元;数据处理模块配置为轮询读取存储于数据存储模块中的轮速数据并进行串行处理;其中,数据采集模块和数据处理模块在同一时间分别对同一轮速数据的不同轮速缓存单元进行处理,如此设置,不仅避免了多路数据同时读取造成的延时和堵塞风险,还消除了现有数据采集系统在对多路信号进行采集存储过程中的来回切换工作,从而极大提升了数据采集效率及数据采集的精度和可靠性。
