基于虚拟仪器的智能车无线实时数据采集系统

Wireless Real-time Data Acquisition System of Intelligent Vehicle Based on VI

在飞思卡尔智能车调试中,需要对运行中的小车参数实时进行采集处理,以便改进设计及对控制参数进行现场整定。为此,提出了一种基于虚拟仪器技术和无线传输的实时数据采集处理系统设计方案。该设计方案采用嵌入式无线通信模块,通过串口进行数据采集,借助LabVIEW图形化的编程方式,快速搭建个性化的数据处理显示平台。具有成本低廉、接口简单、实用性强、功能易于扩展的特点,在实际应用中取得了良好效果。

In debugging process of Freescale＇s intelligent vehicle,it＇s necessary to real-time acquire and handle parameters of vehicle while running,in order to improve its design and on-site set its control parameters.Therefore this paper presents a design proposal of real-time data acquisition and handling system based on virtual instrument technology and wireless transmission.The design uses embedded wireless communication module to acquire data through the serial port.With the aid of LabVIEW graphical programming,designer can build customized data handling and display platform quickly.
