【摘要】 目前便携式汽车废气分析数据固化于硬件,数据储存能力有限,不能连续实时采集数据,且与通用计算机通讯不方便。本系统软件实现了废气排放数据自动的采集,自动保存等功能并克服了同类软件运行不稳定,容易造成数据丢失的缺点,为废气分析提供准确数据。软件界面能动态显示废气分析采集到的HC,CO和NOx等主要排放污染物的数据,并可以动态刷新和存储数据。系统应用于某试验中心汽车燃用CNG/汽油两用燃料的排放测试试验中。更多还原

【Abstract】 For the solidification of data in the hardware,the limit of the volume of data logging,the discontinuousness of saving data,and discommodiousness of communication,the system software was designed for the exhaust gas data acquisition automatically which overcomes the shortcoming of instability and data lost.The software could dynamically display the data of HC,CO,NOx and so forth,and it could refresh in time.Finally it was applied in the CNG/ gasoline fuel automotive test in some test spot.更多还原
