摘　　要：针对国内现有蒸渗仪测控系统测量精度不高,稳定性差的问题,设计了一种基于C8051F410单片机的新型蒸渗仪测控系统。它采用独立电源供电方式,选用高精度A/D转换芯片,并提出了一种改进型递推平均滤波方式,从软硬件两个方面来提高系统的测量精度。经过反复试验,该蒸渗仪具有测量精度高,稳定性好等特点。Due to the poor accuracy and stability of existing domestic lysimeter system, a new lysimeter system based on MCU C8051F410 was designed. Through the aspects of hardware and software, the system adopted independent power supply, chose high precision A/D conversion chip and proposed a modified recursive average filtering method,to improve the measurement precision of the system. As a result, the lysimeter system has the characteristics of high measuring accuracy, good stability, and etc.
