摘要
介绍一种用于汽车控制系统的传感器平台设计方案,描述了系统硬件和软件设计思想。硬件中的模拟前端器件用于获取传感器信号并进行预处理,数字部分的现场可编程门阵列(FPGA)用于数字信号处理,如滤波、信号提取等,模拟模块与数字模块通过桥路连接。软件则用于系统管理。最后,结合一个实际应用的传感器对平台结构进行了分析验证,并给出实验结果。
A design scheme of the sensor platform for automotive control system is introduced.System hardware and software design idea is presented,the analog front-end chip in hardware is used for sensor signal pre-processing,FPGA is performed signal processing,such as filtering,signal pick-up etc,the analog and digital blocks are connected with bridges.The software is used for system management.Finally,the platform architecture is analyzed with an application sensor and the experiment results are given.
