摘　　要：介绍了基于AD7730的发动机燃油消耗测量仪的电路接口和软件编程设计。硬件电路取消零点、增益、基准电压参数手动调整,软件编程设定AD7730的自校准、模拟输入量程。分析了斩波方式、数字滤波、A/D输出速率对有效分辨率、测量精度的影响,以及发动机燃油消耗测量仪应用效果的评价。The hardware and software of the fuel meter based on AD7730 is proposed. The zero, gain, reference voltage adjustment has been cancelled by hardware design. The software set up self-calibration and analog input range of AD7730. The chop mode, digital filtering, A/D output rate for the effective resolution & measuring accuracy are discussed, and the applied result evaluation of the fuel meter.
