The author mainly takes charge of hardware design of the system . in the design , takes the methods of designing signal amplifier and signal acquisition on different circuit boards . this design method deals with analog signals and digital signals separately which satisfies the request of digital instruments design , and resolves the problem of cross - interference between analog signals and digital signals , so the anti - interference ability of the system is greatly improved 作者主要负责进行该系统硬件设计，在硬件电路设计中，采取将生物信号放大器和生物信号数据采集板分开设计的方法，这种将模拟信号与数字信号分开处理的硬件实现方案符合数字化仪器的设计要求，解决了不同性质信号间的相互干扰问题，使系统的抗干扰性能大为提高。
In this thesis , used thermocouple to sense the temperature in the space of the hearth , attributed the thermocouple based on calorifics and scientific arithmetic , acquired data by data acquiring card , processed data according to the demand of setting up temperature model and drawing graphics and then caculated the coordinates of isothermal points and normals of isothermal facets , ascertained the order of connecting points and the model of construct , drawed the isothermal facet of temperature field with opengl at last 通过数据采集板卡进行数据采集并与计算机接口进行数据处理。然后，将处理后特殊点的温度数据依据marchingcubes算法建立数学模型求取等温面上的点的坐标及各点的法向量等。最后，确定计算的三维坐标点的连接顺序和拓扑模型，利用opengl进行等温面的绘制、消隐和模式变换等工作。
Tn this paper , by means of the study on simulation experiment method of piston ring and cylinder friction and wearing , advanced tie data acquire and process system , and develop the a / d hoard and acquirement and processing software . at the same imt i n ~ tk ~ part in the development of the real ? ime demarcate device 本文通过对活塞环?缸套摩擦磨损模拟实验方法的研究，改进了往复式模拟实验机的数据采集和处理系统，研制了数据采集板和采集处理软件，同时参与了在线标定装置的开发。
Usually only select states are available and output feedback is used . it is shown that output feedback , while not as effective as full state feedback , is still able to damp vibration . thirdly , virtual vibration measurement and control instrument is developed using lab view and homemade daq , then experiments are performed to validate the conclusion of analysis results 最后，为了验证在理论分析和数值仿真中得到的结论，利用虚拟仪器软件labview和国产数据采集板开发了虚拟振动测控平台，然后对附加主被动混合阻尼的悬臂梁结构，实现了结构振动控制，实验结果表明主被动阻尼分离结构对低阶模态振动具有更显著的控制效果。
This technique is considered as the future trend of instrument technology . the virtual instrument is one of computer instrument systems and it is based on the hardware of computer . the function of virtual instrument is defined and designed by consumer . the virtual instrument is with virtual panel and the testing function is implemented by software . the traditional instrument implements data analyzing , data processing and data display by hardware circuit , but the virtual instrument implements those functions by computers . though the collection of signal is done by the actual probe , data collection board and the i / o of computer . the virtual logical analyzer is made by the technology of virtual instrument 所谓虚拟仪器,就是在以计算机为核心的硬件平台上,其功能由用户设计和定义,具有虚拟面板,其测试功能由测试软件实现的一种计算机仪器系统。它将传统仪器由硬件电路实现的数据分析、处理与显示功能,改由功能强大的计算机来执行,而信号的采集,仍然利用实际的探针,数据采集板和计算机i / o系统相结合的思想。虚拟逻辑分析仪就是按照虚拟仪器思想设计而成的。
After the analytical structure research of fuzzy controller , this paper has a simulation experiment , and introduces the efpt process - control experiment system which is composed with efpt process - control equipment , data acquisition card pcl726 and pcl812pg , and industrial computer 在解析结构研究的基础上进行了仿真实验，最后介绍由efpt过程控制实验装置、数据采集板卡pcl726和pcl812pg和研华工控机组成的efpt过程控制实验系统，用工业组态软件“组态王”制作控制平台，完成控制和显示画面。
