汽车智能传感器自动测试系统的设计和建立

NOx传感器的开发是出于对环境的保护,它用于检测汽车尾气排放的氮氧化物浓度。在传感器的开发过程中,传感器输出信号的自动测试是一个重要的步骤。设计了一种基于LabVIEW的友好的用户测试软件,用于传感器数据的实时测试、评估和错误检测,该数据通过CAN总线传输。CAN总线是汽车领域中应用最广泛的通信协议之一。基于LabVIEW建立的自动测试系统具有配置功能、CAN总线数据帧的显示和解码、CAN总线错误的检查、解码信息的测试和评估、报表的生成、信号的设置和验证等功能。

Design and Implementation of Automatic Test System for Automotive Smart Sensor

As the purpose of environmental protection,NOx sensor is driven to develop,which is built to detect the concentration of nitrogen oxides in the exhaust emissions of motor vehicles.During the development of smart sensor,the automatic test for the sensor's output message is a significant procedure.A friendly user test software based on LabVIEW is designed for real time testing,evaluating and error detecting of sensor data transmitted via CAN that is one of the most widely and frequently used communication protocols in automotive applications.The automatic test software based on LabVIEW equips with the features of configuration,displaying and decoding CAN data frames,checking CAN errors,testing and evaluating decoded messages,report generation,signal setting and validatiing.
