And it is mainly made up of optic - mechanical system ( including the lens of fixed focus ccd focal plane module and mechanical crust . ) image processing system and controlling computer and so on . each part is independence 该系统以计算机为系统控制处理平台，由光机系统(包括定焦镜头、数字ccd相机、消杂光光栏、机械外壳组成) 、图像处理系统和控制计算机等几大部分组成，且各个部分相互独立。
Server - based reporting lets you centralize report storage and management , set policies and secure access to reports and folders , control how reports are processed and distributed , and standardize how reports are used in your business 基于服务器的报表功能为实现下列任务提供了方法：集中存储和管理报表、设置策略和确保对报表及文件夹的安全访问、控制处理和分布报表的方式，以及设置在业务中使用报表的标准方式。
These settings control how often data is processed , how far the generator is allowed to fall behind the real - time clock , how events are processed , how much data can be received and sent , how distribution data is logged , and how often old data is removed from the database 这些设置控制处理数据的频率、允许生成器滞后于实时时钟的程度、处理事件的方式、可以接收和发送的数据量、记录分发数据的方法以及从数据库中删除旧数据的频率。
These settings control how frequently data is processed , how far the generator is allowed to fall behind the real - time clock , how events are processed , how much data can be received and sent , how distribution data is logged , and how frequently old data is removed from the database 这些设置控制处理数据的频率、允许生成器滞后于实时时钟的程度、处理事件的方式、可以接收和发送的数据量、记录分发数据的方法以及从数据库中删除旧数据的频率。
And a kind of 16 - step automatic selective programmable amplifying circuit is designed in volume resistivity measuring circuit , so as to handle sampling little and broad signal . the control and disposal system with the core of microchip at89c55wd is analyzed on chapter 4 . main function unit such as the interface circuit of lcd display and keyboard , the interface circuit of micro - printer , real time clock ds12c887 , and hardware anti - jamming technique are discussed 本文还设计了以at89c55wd单片机为核心的控制处理系统的外围接口电路及其软件，对主要功能部分进行了分析，主要包括：键盘液晶显示接口及界面设计、微型打印机接口、实时日历时钟芯片ds12c887 、单片机与单片机及单片机与上位机的通信设计以及控制系统硬件抗干扰措施等。
The some fire control system is an advanced multi - senor short range air defense system , which integrated both x and ka bands searching and tracking radars , laser range finder , combined the control computer of subsystem with the master computer , and applied the technology of data fusion 摘要某火控系统集两个频率波段的搜索雷达、跟踪雷达和电视跟踪器、激光测距机于一体，分系统控制处理计算机与系统主计算机相结合，采用了数据融合技术，是一部多传感器集成的现代化防空系统，具有搜索性能好、反应时间快、抗干扰能力强、自动化程度高、使用性能好等特点。
However , these systems will break down if any pat fails . moreover , the measurement and control modules lack of the ability of self - adapting and self - decision . single control and processing system ca n ' t deal with complicated situations effectively when there are many components and many kinds of information 但是，上述系统的可靠性是通过单个设备的可靠性和关键部件的冗余来实现的，往往由于个别环节的故障导致整个系统不能正常工作；各测控节点缺乏自适应性和主动性;当系统的规模比较大、信息种类比较多时，单一的系统控制处理往往不能适应复杂的变化情况。
Plc is widely used in automatic control for its strong function , high reliability , wide applicability , modular structure and etc . many customer services , such as showing process - flow charts , displaying dynamic - data - base interfaces , editing tables , generating charts , managing production and etc , can be provided by connecting personal computers ( pcs ) to a plc network . in a plc - pc system , plcs , which serves as the low - level units , are used to collect and control the data , ( for example , the on / off quantities and analog input / output quantities ) 把个人计算机连入plc网络可以向用户提供诸如工艺流程图显示、动态数据画面显示、报表编制、趋势图生成、窗口技术以及生产管理等多种功能，作为底层单元的plc完成对现场开关量、模拟输入输出量的控制处理，而利用微型计算机良好的人机对话界面和数据处理功能，实现对一台或多台plc进行监控，充分发挥plc可靠、灵活的控制性能和计算机在管理、监控等方面的优势，提高控制系统的整体自动化程度。
