海南LED显示屏设计方案

videoconference, Secretary of the provincial Committee of Xia Baolong stressed: this year is the five water treatment 357 timetables for three years to resolve outstanding issues, obviously worked, victory of the year. The Countys departments at all levels must firmly establish the guanghui is gold and silver green development concept, convinced that Castle is not relaxed, always maintaining strategic ability and strong determination to improve the environment, consistently playing well five water treatment of winning the war, ever-higher levels of comprehensive well-off society was built. (A) lay the sewage uphill battle. This year we will river water quality improved at the county level, up to five this basic objective grasp of pollution control that focus, with the focus on three things: a good job, clear rivers reaching the County created. Organization look back special inspection, the County garbage River, black and odorous River is Dragnet investigation, timely rectification of problems found in place firmly to prevent river pollution rebound. In accordance with the one-stop strategy, improving the inferior five water quality monitoring stations work this year to ensure the Elimination of 1 provincial control, five water quality section 3 municipalities controlled deterioration, ensure the creation this year of clear rivers standards. Second, pay special attention to pollution-cutting construction of nanotubes. Intercepting nanotubes are the basis of pollution of water source engineering, engineering, matter of success or failure of water management. Urban sewage treatment, to improve effluent from sewage treatment rate, running accuracy, compliance requirement, speed up the towns support network construction, is focusing on nanotubes home last meters question. Domestic sewage treatment in rural areas, this year is the final year of the three-year action, determination to fight and the momentum around, ending the battle on which fully to ensure the realization of all County 648 formed village coverage. Also, be sure to attach importance to focus on rural domestic wastewater treatment facility operation and management, ensure that wastewater treatment facility up and running, role play, avoid the Sun problem. Third, pay special attention to the River Lake pond desilting operation. Provinces now have focused on pollution control of water go to dig up mud, as the deepening water of this years plays. Next, to jump-start an investigation line touches work, implementation plan according to the priorities and the programme of work, in accordance with the one river one policy requires detailed cleaning, dredging plan, planning ahead of time cleaning out mud way out, according to local conditions to do sludge, promote scientific resource utilization of silt and mud. (B) the heavy regulation of heavily polluting industries. Pollution of water must grab the source, wastewater is primarily the source of backward production capacity, increase the intensity of LED显示屏设计方案一、概述为实现信息的即时发布，我局拟在办公楼主楼大堂的西面和北面墙身上各建设一个LED显示屏，为我局的信息发布提供一个平台。目前，我局办公楼主楼大堂的西面（图1）和北面（图2）墙身上有两个信息栏，见下图图1图2拟将这两个信息栏改造为LED显示屏，效果如下图所示（图3、图4）。在图3的大屏上主要以发布信息为主，图4的小屏上主要显示局领导的值班安排信息。LED显示屏上的信息通过两台计算机进行发布，其中，大屏的信息拟由指挥中心公共关系科负责发布和维护，该计算机设置在公共关系科。另外，小屏的信息拟由指挥中心指挥室负责发布和维护，该计算机设置在指挥室。图3图4二、系统总体结构 系统总体结构图如下所示：（图6）图6各部分说明：1、显示屏屏体是显示屏的最终显示单元，屏体为积木式模块结构，模块之间由信号线级连，电子部分具体由3.7双基色矩阵、显示控制电路、驱动电路、电源系统等组成。2、信号接收板信号接收板是显示屏的控制核心，它接收来自计算机显示屏数据专用发送卡发送的信号，同时向屏体输出显示所用的各种控制信号。3、显示系统系统可分为支持环境和节目的制作/播放环境。其中支持环境, 包括操作系统(DOS、WINDOWS), 多媒体卡驱动程序。 节目的制作/播放环境是一整套工具软件包, 提供对节目的编辑管理和播放。系统也可以接收局域网上传来的数据，经软件处理后，通过专用的信号通讯卡，把控制信息及数据信息发往显示屏主控系统，由主控系统把相关的信息送往各相关的模块。4、配电系统将外电通过双极带漏电保护开关，然后分别用双极人气空气开关进行电源的控制。三、系统设计方案1、建设内容将原信息栏拆除，增加两个LED显示屏，大小分别为：大屏有效显示面积：4.88m(w)1.68m(h)=8.20m2 小屏有效显示面积：1.22m(w)1.52m(h)=1.85m2显示屏电源可从大堂北面的电箱取，通讯线路从天花拉到南面线路房。其中，大屏的通讯线路走管线到市局南楼一楼公共关系科，小屏的通讯线路走管线上十二楼指挥室，分别与计算机连接。2、设计方案2.1显示屏显示屏由双基色矩阵组成，发光管芯参数如下表： 法向光强(mcd)尺寸（m）垂直视角水平视角峰值波长材 料红30280280160160640 nmGaInN绿25254254160160570nmGaInN2.1.1 象素灯 ：双基色矩阵由1红、1绿发光芯片组成，单点像灯发光强度为50mcd。其结构如下图2.1.2 视 角 ：象素垂直视角160,象素水平视角160 2.1.3 寿 命 ：(1)发光器件的寿命：矩阵10万小时。 (2)显示系统寿命：由于显示系统除发光器件外，还有IC器件等组成，对各组成部分综合考虑显示屏系统寿命应为5万小时。 2.1.4 双基色模块：单个矩阵尺寸结构如下图模块点阵：6432点 象素间距：4.76mm 模块几何尺寸：304.8mm152.4mm2.1.5 显示尺寸（大屏）：总点数：1024352=点 模块数：1611=176个 有效显示面积： 4.88m(w)1.68m(h)=8.20m2 显示字数：满屏可显示22行，每行可显示64个中文字，每个中文字尺寸：7.62cm7.62cm显示屏哑光不锈钢喷涂包边尺寸：5.05m(w)1.85m(h)密度：44135点/米22.1.6 显示尺寸（小屏）：总点数：256320=81920点 模块数：410=40个 有效显示面积： 1.22m(w)1.52m(h)=1.85m2 显示字数：满屏可显示20行，每行可显示16个中文字，每个中文字尺寸：7.62cm7.62cm显示屏哑光不锈钢喷涂包边尺寸：1.39m(w)1.69m(h)密度：44135点/米22.2 控制参数： 驱动方式：扫描驱动 亮 度： 2200cdm2 显示彩色数： 红、绿各256级灰度，65536种颜色换帧频率：VGA同步 72帧秒 视频同步 50帧秒 扫描频率：100次秒 通讯标准：RS-422A标准2.3 系统参数： 供 电：2200VAC30V（单相三线制） 50Hz3Hz 功 耗：最大6.2KW 平均2.8KW 使用环境条件：室内使用 工作温度：-15+50 存贮温度：-40+60 工作湿度：20%95% 存贮湿度：95%2.4 电源： 效率：80输入特性： 工作电压：160VAC260VAC 频 率：47Hz53Hz输出特性： 纹 波： 控制电源50mV 驱动电源100mV 线路调整率：1 负载调整率： 1 上升时间：不超过350ms 保护功能： 过流保护：额定输出的115 过压保护：额定输出的120 欠压保护：额定输出的80 联系人曾显；电话:LED显示屏渠道第一服务商。LED显示屏高清专家。深圳亿光科技强势推出“黑芯”系列室内全彩表贴三合一PH2.5.P3.

According to municipal, and municipal government deployment of seven big heavy pollution industry regulation three years action plans, requirements to December 2016 end of Qian, all included shut stopped eliminated of enterprise all shut stopped eliminated in place; June 30, 2017 Qian, all included place regulation upgrade and agglomeration restructuring of enterprise by unified standard regulation in place, late not standard of enterprise are implementation discontinued; June 30, 2018 Qian, all intends Park production of enterprise relocation Park in place, late not Park of are discontinued. In the process of renovation, will focus on four aspects: to firmly close the high energy consumption and heavy pollution, hopeless enterprise governance and production lines, eliminated a number of yearly emission intensity, low value-added products of backward production capacity. Second, we must strictly enforce the space, total project Trinity environment access system, promoting industry access and environmental conditions of access of enterprises to the Park, industrial park, in principle, no longer the class on the new project. Thirdly, promoting replacement and reconstruction of heavily polluting industries, mergers and reorganizations, guide enterprises to energy conservation, recycling and low-carbon and clean production, and improve the level of green development. Four to establish a long-term supervision mechanism, increase the intensity of special inspections, investigate and punish the rectification is not in place, normal business of running anti-pollution installations do not. (Iii) linkage to promote flood control water, drainage, water supply, improving water saving. Speed up cross Yang support river dike reinforcement, and along Pu seawall except insurance reinforcement, and Lake Qian sluice, and BA Cao sluice, and cloud cover reservoir, focus flood control drainage engineering construction, vigorously implementation strong library solid di spread row engineering, increased geological disaster hidden points governance efforts, solid advance small basin torrent disaster governance, efforts from essentially solution
