智能建筑弱电工程设计的若干技术问题

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 County s 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 town s 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 year s 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 treatment of heavily polluting industries 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 basin sex and regional flood control drainage capacity insufficient of problem Vigorously implement the piers algae and other water sources protection and promoting rural drinking water safety projects setting up water pricing reform and environmental protection mechanism guiding water depth Further soil pollution and repair strengthen agricultural non point source pollution prevention mountain water forests fields lakes various elements mutual long Four manage to tighten control to play three to split battle Xia Baolong Secretary of provincial party Committee stressed that while the three to split operation time is over three years but three to split must continue to catch on and resolve a split cannot be changed All localities and departments to the village and no unauthorised created 近年来 智能建筑以适应时代发展潮流 符合人们追求安全 舒适 便捷需求的鲜明 特点 在社会上广受关注和欢迎 在其推广应用过程中 由于人们熟悉上的误差 工程实 践经验的不足 也出现过一些曲折和发展不平衡的问题 影响了智能功能和效益的正常发 挥 本文将通过几年来从事智能建筑行业实际工作经验的总结 提供一些处理问题的做法 和观点 供各位同行在今后的工作中参考借鉴 一 切莫贪大求全 但求专 精 经济实用 作为现代建筑不可缺少的配套专业 智能化系统工程同样受到技术 经济和时间等因 素的制约 必须根据建筑物的专业特点与使用需求有机地紧密结合起来 综合考虑其使用 功能 治理和经营要求 工程投资能力等因素 分清主次 突出重点 保证主要功能 选 择适用的各个专业子系统 系统集成程度 标准等级和经济规模 例如 智能型办公大厦就要突显其办公自动化 通信网络化等方面功能定位 大型公共建 筑就要突出专业服务功能和业务治理设施等 技术环境和水平的提升 又如 视频点播系 统在旅馆 酒店行业较为常见和实用 而在其他服务行业却并不尽然 在星级酒店旅馆中 电子门锁已得到普遍应用 而其他场合只会设在某些非凡重要机房和安全等级高的关键部 位 工程设计上要因地而宜 前几年 某些工程从商业利益出发 追求广告效应 片面地强调所谓 nA 功能 含大求 全 什么功能都想要 而实际上缺乏统一规划 设计考虑不周 出现偏差 必备的相关设 施和配套环境不能及时跟进和提供 结果智能化系统成了摆设品 头脑发达 四肢不灵 发挥不出应有功能和作用 投资也得不到回 这类例子并不少见 因此 应从此类案例上 吸取深刻教训 从实际需要出发 在工程设计一开始时 就全面地做好智能建筑的规划 设计和配套工作 二 跟踪主流技术 走成熟 可靠 稳健发展的技术路线 智能技术发展日新月异 工程设计上应注重当前 IT 产业发展动态和趋势 紧跟智能建 筑技术发展主流 同时要注重智能建筑工程与科研和开发工作极不相同 它通常只能一次 性成功 工程现场不具备反复变动 多次试验的条件和可能 而且受工程周期和进度的限 制 工程投资的约束则更为明显 因此 在实际工作上 要慎重选用某些新技术 除非有 稳妥 可靠的保障措施 通常 要以采用可靠 成熟 稳定的先进技术为原则 选用经过 市场考验 实践证实可靠和成功的产品及设备 一般情况下 已批量生产和投入使用的系

three years but three to split must continue to catch on and resolve a split cannot be changed All localities and departments to the village and no unauthorised created 列化品牌产品是设计上首选对象 同时 要考察产品兼容性 升级换代的可能性 技术上 开放性 市场上技术支持度 以及厂商在当地技术服务和支持的能力 十兆 百兆 千兆以太网组网技术的发展过程 给了智能化工程一个有益启示 稳健 地追求技术先进性 对工程成功 系统具备生命力至关重要 三 遵循因地而宜 实事求是 科学合理的原则 每一系统和设备都有其适用范围 功能和性能上的局限性 设备不是 万能 的 贪 图所谓 最好 最新 最全 的观念 是不切实际的看法 例如 某会展中心大型展 厅配置公共业务广播系统 是按照普通语言扩音标准设计的 曾有某承包商为了提高造价 竟宣称其能在大型展厅做到音乐厅 影剧院的音响效果 多次要求变更原设计 增加设备 更换档次 这在建筑声学等条件满足不了 设备上也做不到 实际上也没必要的要求 其 结果当然是被驳回 否则 不但产生不合理投资 还可能因原因 责任不明引起纠纷 又 如 某一工程为了满足局部现场教学转播的业务需求 设计上不恰当地与安保闭路电视监 控系统合在一起 整个系统复杂化了 技术等级和标准随之提高了 图象质量还达不到规 定要求 使用上既不灵活 也不方便 经纠正 改为二者分开 另设一套专业电视录播小 型系统专用于电视教学转播 既满足使用要求 又简化系统 不增加造价 使投资更为合 理 四 重视系统可用性 稳定性和可靠性问题 建筑智能化系统使用寿命可能少则几年 十几年 多则几十年 通常投入使用后要 24 小时不停机运行 肩负着保障建筑物内各类活动 人身安全的任务 除要注重设备和系统 选型外 对要求较高的场合 应有其他的技术保障措施 例如 双机热备份 软件备份 热插拔硬盘或使用 RAID 增加系统冗余量 增设 UPS 电源 采用强制散热 快速恢复措施 等 要求 7 24 小时运行的非凡系统 更应强化可用性 应急治理 安全保护等方面的保 障措施 根据以往工程经验 诸如消防警系统 楼宇自控系统等输入 输出控制点数 不宜超 过其系统最大可用容量的 80 扩音系统负载的实际消耗功率宜控制在额定输出功率 70 以下 应注重采用设备厂商的设计推荐值 五 妥善处理需求和成本关系 提升系统性价比 工程上要考虑在满足使用要求前提下 尽量简化系统 降低投资和运营成本 不同的 videoconference Secretary of the provincial Committee of Xia Baolong
