摘　　要：在改造原有钟罩式气体流量标准装置检测系统的基础上,进行标准体积的离散化,提出了定标定检、实时采集、动态修正的方法,采用上下位机,提出了一种改进系统精度的方法。与此同时上下位机分工合作(下位机实现实时响应,上位机实现系统的数据处理和信息化),大幅提高了整个系统的精度和自动化程度。This system introduce upper and lower computer system into the already used apparatus - the bell housing standard apparatus of gas-flowing measure system, This system uses single chip PIC system to gather the data of the high definition, adopting the PC system to deal with the data which is gathered by the PIC at background, the accuracy of the bell housing measure system got a lot exaltation; at the same time, also Increased automation degree, simplified the measure flow process, increases measure efficiency.

关 键 词：钟罩式气体流量标准装置 上下位机 USB总线
