DATA C-3高速数据采集系统(简称C3系统)具有多种数据采集功能,特别适宜动态测量以及对测量数据进行常规或超高速处理和分析。p_i仪用来同步测量活塞式机械气缸内的平均压力,具有定确上止点、计算2~n个工作循环的平均p-v和p-α图等多项功能。在内燃机工作过程研究与其性能测试工作中,C3系统和p_i仪得到广泛的应用。但是,由于C3系统和p_i仪做为精密仪器,自身体积大、重量大,不宜在现场工作,或做远距离的搬运,从而限制了它们的应用。
The DATA C-3 high-speed data acquisition system (C3 system for short) has a variety of data acquisition functions, especially suitable for dynamic measurement and routine or ultra-high speed processing and analysis of measurement data. p_i instrument used to simultaneously measure the average pressure inside the piston mechanical cylinder, with a definite top dead center, calculate the average p-v 2 ~ n work cycle and p-α map and many other features. In the process of internal combustion engine research and performance testing, C3 system and p_i instrument has been widely used. However, due to the C3 system and p_i instrument as a precision instrument, their own bulky, heavy, should not work in the field, or do long-distance handling, thus limiting their application.
