基于PC实现二次仪表型消光式烟度计的数据实时采集

通过对二次仪表的改造，实现了基于个人计算机的二次仪表型烟度计的数据实时采集，解决了二次仪表型烟度计不能反映摩托车瞬间排烟状况和数据采集不准的问题，并实现了软件的自校功能，弥补了二次仪表的自校缺陷；同时添加了数据的奇异性检验，消除了因试验环境的干扰所造成的奇异数据。采集数据可根据不同的试验方法进行数据处理、存盘与打印相关试验报告。

Realization of Real-time Data Acquisition of Traditional Instrument Smoke-meter

Having improved the traditional instrument, the real-time data acquisition of traditional instrument smoke-meter based on PC is realized, which resolves the problem of inaccurate data from the traditional instrument. The curves are plotted well on the PC reflecting the situation of the smoke exhausted from the motorcycles. Self-calibration is improved. The interference from surroundings is eliminated through inspecting the data. The program can analyze, save the data and print the report by the different test methods.
