汽车记录仪数据采集系统的设计

从硬软件的角度研究了基于 S3C2410的汽车记录仪数据采集系统的设计,对采集系统中三大主要模块即:实时时钟信号模块、车速采集模块、开关量模块分别进行了研讨,经过实验证明,将此采集系统应用于汽车记录仪中,该采集系统采集精度高,抗干扰性强,性能可靠,价格低廉,具有很好的应用前景和较高的通用性与实用性。

Design of vehicle data recorder acquisition system

This paper investigates the data acquisition system of vehicle recorder based on S3C2410 from the perspective of hardware and software.Acquisition system has three main modules:real-time clock module,speed acquisition module,and switch module.The experiment proved that this acquisition system used in automotive recorder has high acquisition accuracy,strong anti- interference,and achieve good results.At the same time it is reliable and inexpensive,and has a very good prospect of applica- tion,higher general and better practicality.
