After being buffered , read by blocks and plus - width - modulating ( also called pwm ) , the digital video signal will be converted into scanning signal for color moving picture and then be outputted to the display board 系统将多媒体视频卡输出的数字视频信号进行数据缓存、分块读取和脉宽调制等处理，形成符合显示板结构的彩色运动图像扫描信号，输出到显示板。
The video picture of computer was scanned to the display board of huge screen . because of the speciality of led material , the method of signal control is digital . so the system is a typical application of signal processing of digital video 本系统将计算机视频图像扫描到大屏幕显示板上， led器件特性决定了信号的控制是全数字式的，是数字视频信号处理系统的一个典型应用。
For the existing situation of primary air speed monitoring condition on boiler , a new instrument structure mode whose data acquisition board and display board are separated , and connected by communication to improve the reliability , reduce the cost and easy installation and maintain 摘要针对锅炉一次风速监测仪表的现状，提出一种新型仪表构成方式，将测量仪表的现场数据采集和显示功能分离，之间采用通信方式连接，以提高仪表的可靠性，降低成本，方便安装和维护。
Nevertheless , as the simulating technology involves the integrated high - techs and knowledge of computers , networks , images and graphs , multi - medias , software engineering , information processing and automated control , the simulating system is affected by its own characteristic - featured conditions , running environment and training requirements , thus yielding many problems that exist in our marine engine room simulators being currently used . for example : the mers system has poor working stability and high rate of breakdown ; its viewing device is yet to be updated , as the true aspect of the engine room can not be seen during training ; the teaching display board can not display the running state of the system with 3 - d animations , neither can it change the dynamic flow chart , etc . the afore - said problems have been greatly retarding the seafaring teaching and training , and restricting the application value of mers , as a consequence 但是，由于轮机模拟器仿真技术综合了计算机、网络技术、图形图像技术、多媒体、软件工程、信息处理、自动控制等多个高新技术领域的知识，仿真系统受到了其特有的制约条件、运行环境和训练要求的影响，现行轮机模拟器在应用中还存在着许多问题，如：轮机模拟器系统工作稳定性差，故障率高；视景装置落后，训练中见不到机舱真面目；示教板不能用三维动画来显示设备运行状态，不能更换动态流程图等。
" through a series of exhibits , display boards , interactive games and a video show , the centre features various types of fishing vessels , fishing gear , seafood and fisheries management measures , " director of agriculture , fisheries and conservation mr thomas chan said at the opening ceremony of the centre today ( september 30 ) 渔农自然护理署署长陈镇源主持渔业教育中心开幕礼时说：捕鱼业在本港有悠久历史，中心透过展品、展板、互动游戏及教育短片，介绍本港各式渔船、捕鱼用具、海产，以及渔业管理措施。
Thereinto communication with host machine comes downto time ' s checking and synchronization , the corresponding method is combined with valid calling core and makes the delay to the least . we also use the display board with electronical map and settle the matter of orientation . to the problem of historic data , we have resolved the redundance of data and reduced the space of data ' s copying 其中与报警主机接口的通信处理涉及到校时和同步，相应的处理方式采用了结合系统内核的高效调用，将延时降到了最小；而对报警方位的显示处理则采用了显示板结合电子地图，直观而有效的解决了定位问题；针对历史数据的处理，则结合了处理信息的特点，有效了解决了数据冗余问题，缩小了数据备份空间，而且在一定程度上提高了数据存储的效率。
To enhance the involvement of teachers , staff , students and parents in this scheme and strengthen their environmental awareness , " classroom display board design competition " environmental handicraft design competition " were launched in late 2004 . all pre - school teachers , staff , students and their parents were invited to join 为了提高幼儿学校的教职员学生及家长对计划的参与性，并加强他们的环保意识，我们于2004年底推出以环保为主题的课室壁报板设计比赛及环保手工艺设计比赛，所有幼儿学校的教师员工学生及家长均可参与。
The system is consist of the main data processing board which is based onthe fpga device and fast ethernet phyceiver rtl8201l and a - law pcm data encoder and decorder chip msm7702 - 3 , and the dial - up and display board which is based on mcu . the main board would carry out the core task of data processing , such as voice data packing and unpacking , the ethernet frame processing , protocol processing , call processing , etc . the dial - up and display board would carry out the task of display the ip address which is input by consumer and status of network during talk period from the main board , and so on . in the paper the system of lan ip telephone and the tcp / ip protocol is introduced firstly , then the fpga device is stated . after that the fpga - based hardware scheme is introduced in detail in chapter four 系统以altera公司的acex1k系列的fpga和快速以太网控制器rtl8201l和语音编解码芯片msm7702 - 3为核心构建了数据处理主板和以单片机为控制器的拨号显示子板组成。数据处理主板的核心任务，包括语音数据处理、以太网帧处理、协议处理、呼叫处理等。拨号显示子板则完成通话前的显示用户所拨过的ip地址，通话期间网络状态的显示等等。
Servicing the 23 special - ward area and parts of the tama area , the toei bus system is used daily by approximately 570 , 000 passengers . in response to delays caused by traffic congestion , the bus operational control system was introduced to inform passengers of approximate bus arrival times . buses are installed with a device designed to automatically assess travel time in order to send information to display boards located at bus stops along the route 运行于东京都和多摩部分地区的都营巴士，每日使用的乘客接近57万人，为处理交通堵塞晚点问题，引入巴士运行管理系统,告知乘客汽车抵达的大致时间，巴士还安装了自动估测旅行时间的装置，并将信息发送到沿路车站的显示牌上，乘客可以看到这些展示牌信息或把信息下载到手机或电脑上。
The sampling data are displayed by 7 - segment leds that are designed in a dependent pcb , the display board has a serial interface which use less pins of mcu . it ' s a efficient way . at last the outputs by calculation and reference of fis control the capacitor - group and voltage adjuster by relay - group , the whole device is divided into three part , the first part is sampling & control board ; the second part is display leds board and the third part is supply & output board 在电压无功综合控制器的设计中，考虑到mcu管脚有限且要求显示的数据较多，使用了较多的spi接口形式的外围芯片(如cs5460a 、 ezprom ) ，而且将数码管显示部分设计为串行数据传输模式，这样其数据线也可以利spi接口的数据线复用，提高了mcu管脚的利用率也保证了功能的实现。
