驾驶机器人数据采集系统的设计

Design of data-acquisition system for robot driver

摘要:

针对汽车排放耐久性试验用驾驶机器人信号采集的要求，以提高数据采集的可靠性和实时性为主要目的，设计了一种用于自动驾驶机器人的多路传感器数据采集系统，硬件部分主要由传感器、调理电路和数据采集卡ACL8112组成，软件部分主要包括数据采集卡驱动和功能函数，实现对汽车主要工况数据的实时采集。试验结果表明，该数据采集系统在20 ms的采样周期下工作正常可靠，较好地满足了驾驶机器人对数据采集的要求。

Abstract:

To meet the requirements of the robot driver for automobile emission durability test，a multi-sensor data-acquisition system was designed. The reliability and real-time performance of data acquisition were improved. The hardware system consisted of sensors，conditioning circuits and a data-acquisition card ACL8112，while the software system consisted of the card driver on Linux and performance functions. The main floor data were sampled during robot driver’s working. It is shown that the system works reliably in the sampling period of 20 ms.
