Software design includes many aspects , such as design of interface , interrupt and clock control , monitoring , etc . sampling and accessing quickly data of chromatogram peak is an important tache to ensure analytic and real time performance of chromatograph , fifo make high - speed input and output of a / d sampling data possible , and expended memory , instead of disk , save a great deal of peak data and process parameter 硬件系统由cpu 、 a / d 、 d / a 、显示驱动、实时钟五个模块组成，软件设计包括谱峰数据的高速采集和存取、人机界面的设计、中断和实时钟控制、监测控制等方面的工作。谱峰数据的高速采集和快速存取是保证工业色谱仪分析性能和实时性的重要环节，采用了fifo存储器技术实现a / d采样数据的高速输入输出，使用扩展内存代替硬盘存贮过程参数和海量的谱峰数据。
The test system we discussed is made up of a personal computer , hard wares with various functions , graphical interfaces application software labwindows / cvi which is used to analyses data and process communication . it made the computer to be a numeral platform with various test functions 本课题建立的测试系统由个人计算机、各种功能硬件模块与用于数据分析、过程通信及图形用户界面的应用软件labwindows cvi有机结合构成，使计算机成为一个具有各种测量功能的数字化测量平台。
This step is concerned with gaining a good understanding of the business and information needs of the business area under consideration . it highlights unsatisfactory services within the current environment and additional functions and data required in the new environment . it is not , however , recommended that detailed data and process models be constructed 这个步骤著重于了解清楚有关的业务及业务范围内的资讯需要，和现时未如理想的服务，与及认定在新环境所需要的额外功能和数据，但并不建议制定详细的数据及程序模型。
The double dsp devices are used to sample data and process the signals in the power disturbance monitoring and analyzing part . the power quality conditioner integrates active power compensation with passive power compensation , and improving power quality with improving power factor . the conditioner circuit consists of tri - level pwm converters , in which there are two active power filters ( apf ) that is a shunt apf and a series apf 电能质量监测分析系统采用双dsp实现系统的采样、信号处理，完成电能质量全程监测与分析；电能质量调节系统则采用有源与无源、改善电能质量与改善功率因数相结合的策略，有源部分以三电平pwm为主电路，由并联和串联apf ( activepowerfilter )相结合、共用直流电源，构成其主体框架，并以无源调节配合有源调节来降低系统的综合造价，力图将电能质量调节技术在10kv配电系统中得到实用与推广。
In the third part , the application of quality control system is summarized . in the chapter three , the important technologies in lims are analyzed , such as visual equipments " technology ^ the technology of interchanging between laboratory data and processing data > unified chromatography data style technology and web system of browser / server 在第三章中，主要介绍了实验室信息管理系统中所涉及的关键技术，如虚拟仪器技术、实验室分析数据和过程数据集成、建立统一的分析数据和质量信息标准、以及建立browser / sever的网络体系。
