【摘要】 为满足实际应用要求,设计一种新的制动系统气压传感器测试平台。该平台以DSP系统为核心,包括气压传感器、制动系统气压模拟装置、汽车气压仪表以及上位机。DSP接受上位机的实验指令后,气压传感器通过调理电路送给DSP系统板以实时测量当前实际气压值,并传递给上位机进行同步显示。测试结果表明:该平台人机界面友好,操作简单方便,可应用于气压仪表及气压传感器的参数测试、标定及相关的培训教育等领域。更多还原

【Abstract】 To meet the requirements of practical application, a new measurement platform for pressure sensor was designed. The platform is based on a DSP system, including the pressure sensor, simulation device of brake system, automobile instrument for pressure and a host computer. DSP receives experimental instruction from the host computer, then gets a real-time measurement of the current actual pressure value from the pressure sensor by conditioning circuit, and passes to the host computer for simultaneous display. The experimental results show that the platform has a friendly interface,and is easy to operate,can be applied to the pressure instrument and pressure sensor parameter testing,calibration and related training and educational fields.更多还原
