The host record computer of data acquisition is the embeded pc 104 system , the pc 104 system satisfies the highest sampling rate applying effective buffer technique and storing data in the interval of collection 利用嵌入式pc104模块管理大容量的硬盘来解决大量数据的缓存、存储的问题。软件设计采用有效的缓存技术，采集间歇时间存盘，满足本系统采样率的最高可能需求。
Through encoding and decoding functions , the software development company can send important data files into the hardware lock for encoding first , and then save the data after its being encoded . thus , it can keep the security of data 透过编码与译码的功能，软件开发公司可以将重要的数据文件先传至硬件锁中进行编码的工作，当数据完成编码后再存盘，如此便可以保持数据的安全性。
It may at the same time hold many money games if playing to join card store plate to at the same time coexist , may at will add to delete , playing each to use is independent to store a plate of district , stabilize reliability , store plate return can dao enter derivation , preserve for a long time 多游戏合卡存盘同时共存可同时容纳多款游戏，可随意的添加删除，各游戏使用独立的存盘区，稳定可靠，存盘还能导入导出，长期保存。
The simulating system combines the inertial sensor real - time simulator and strapdown inertial navigation real - time simulator . its functions are : the setup of sensor performance parameter , the simulating data dynamic and real - time display and output , real - time save , simulating data to 仿真系统综合了惯性器件实时仿真、捷联惯性导航实时仿真，并具备器件性能参数设置、仿真数据动态实时显示和输出、实时存盘、数据回放功能。
Virtual instrument has shown a new tendency with the development of intelligent instrument . and in some measurement , data acquisition lasts long time and a great many data must be transferred to pc , which needs a new system to acquire data and save them in real time 虚拟仪器已成为智能仪器发展的主流趋势，同时，在实际测试领域应用中，有一些数据采集过程要求有长时间、大批量的数据吞吐能力，要求数据能够实时采集实时存盘。
The relevant transactions include data sampling , graph display , saving , alarm , and default handling , etc . the scheduling scheme in rtdbs adopts the static table - driven scheduling assisted with the other scheduling to meet the need of timing limitation of real - time affair 相关的事务主要是数据采集事务、图形显示事务、存盘事务、报警事务、事故处理事务等。实时数据库的调度策略根据组态软件通讯特点采用静态表驱动为主其他调度策略为辅的调度方案。
Application program mainly contains a multi - thread program , including main control thread , preview thread and encoding thread . main control thread initializes encoder end system and deals with control message delivered from user interface ; preview thread reads preview data and displays it on the screen by the way of user ’ s request ; encoding thread reads encoded data and transfers it to server process . according to user ’ s requirement , server saves the encoded data or transfers it to client by network 主控制线程实现整个编码端系统的初始化和处理用户界面传下来的控制信息;预览线程从编码系统读取预览数据并按照用户界面传下来的要求在屏幕上显示预览视频;编码线程从编码系统读取编码数据并把数据转发给服务器进程,由服务器进程实现数据的录象存盘或通过网络向远程客户端传输。
Divider , coaxial line , trigger , signal processing , data acquisition , acquisition control and waveform analysis software is included in the device . when the device operate in the system , overvoltage is transferred to coaxial line by the divider . if the overvoltage amplitude is higher than initialization value , data acqusition card start sampling . when sampling is over , computer save data to file . engineer can analyse parameter of waveform by appropriative software reading data from file 当装置在线运行时，系统中出现的过电压信号通过分压器传递到同轴电缆，通过触发电路判断，如果大于预先设定的值则启动采集卡的同时采样，采样结束后，计算机把数据存盘并以文件格式保存，管理人员随时通过调用专用软件调取文件进行各种参数分析。
Flight test graphics monitoring system is one part of flight test data processing system - ftdas - of the certain company , which completes the tasks of remote measure data adapting , remote measure data processing firstly and graphics displaying , net transmission , saving , printing of the remote measure data processed firstly , and so on 飞行试验图形监视系统是某公司ftdas飞行试验数据处理系统的一个子系统，它主要完成飞行试验遥测数据采集，飞行试验遥测数据的一次处理，及一次处理后的遥测参数的图形显示、网络传输、存盘、打印等任务。
