【摘要】：我国目前正处于国民经济快速发展时期,随着城镇化占全国比例的不断增加,建筑物带来的大量能源消耗也持续增长,已经成为全社会总能源消耗的一个巨大部分,建筑物的能源节约工作已经变得越发重要。随着社会的进步及经济的不断发展,建筑物的使用者对自身工作生活环境的使用要求也在不断的提高。为了达到节能建筑物这一建设目标,只有将各项不同性质、不同类型、不同用途的建筑设备纳入到一个集中的、统一的、智能的信息化系统之中,使用这一信息化系统对受系统控制的建筑设备进行监测、控制及管理,使建筑设备乃至建筑物具备智能化,这样就能够向建筑物的使用人员提供一个高安全性的环保建筑,这一建筑同时具备节能、健康的功能,还能够满足使用者对工作、生活环境高效便捷的使用要求,楼宇自控系统正是顺应了这一潮流而诞生的。作为智能建筑的重要组成部分,楼宇自控系统的主要功能是实现对建筑物乃至建筑物群之内的各类建筑设备进行监测、控制与管理,满足建筑物使用人员的各项使用需求,同时,还可以通过对建筑设备的运行方式与管理手段的各项优化操作以达到降低各类设备运行、维护成本支出的目的,减少因使用不当而造成的能源消耗。楼宇自控系统涉及建筑设备的各个方面,与建筑使用者的使用感知密切相连,楼宇自控系统是智能建筑中覆盖面最广、涉及设备类型种类最多、设计工作量最大、施工需协调工作量最多、施工工程量最重的一部分,智能建筑的各项使用功能在很大程度上取决于楼宇自控系统的设计质量、施工工作的完成质量和完成水平。论文在说明智能建筑(IB)及楼宇自控系统(BAS)的发展历史、楼宇自控系统的主要组成、系统功能及实现方式的基础上,重点对甘肃移动生产调度楼项目楼宇自控系统进行了设计及实现。设计提出了“集中管理、分散控制”的建设方案,运用了分布式控制系统(DCS)、直接数字控制器(DDC)等技术实现系统,完成的工作主要体现在如下几个方面:(1)对甘肃移动生产调度楼楼宇自控系统建设需求进行分析,主要完成了冷冻站设备、空调设备、新风设备、给排水设备监控子系统及变配电设备监测子系统需监控设备数量、各类型信号数量的统计及分析。(2)根据实际项目需求,提出了系统设计方案,并从系统整体设计、各子系统设计、设备硬件配置、各子系统控制流程等方面着手,对楼宇自控系统进行了设计及实现。(3)对完成的整体系统,从系统登陆、设备状态监测、设备远程启停控制、故障设备报警、接口系统设备监测等方面内容进行了测试和分析。结果表明,系统功能和各项技术性能指标满足设计要求。(4)以“提前关停水冷机组利用管道内冷冻水剩余冷量制冷”的节能策略运用为例,分析了使用楼宇自控系统所带来的节能效果,节能比例达到7.5%。
[Abstract]:At present, our country is in the period of rapid development of national economy. With the increasing proportion of urbanization in the whole country, the large amount of energy consumption brought by buildings has also continued to increase, which has become a huge part of the total energy consumption of the whole society. Energy conservation in buildings has become increasingly important. With the progress of society and the development of economy, the users of buildings are increasing their requirements of working and living environment. In order to achieve the goal of building energy-saving buildings, only the construction equipment with different properties, different types and different uses can be incorporated into a centralized, unified, intelligent information system. This information system is used to monitor, control and manage the building equipment controlled by the system, so as to make the building equipment and even the building intelligent, so as to provide a high safety and environmental protection building to the building users. This building has the function of energy saving and health, and it can also meet the users' requirement of working and living environment efficiently and conveniently. The building automatic control system is born in accordance with this trend. As an important part of intelligent building, the main function of building automatic control system is to monitor, control and manage all kinds of building equipment in buildings and buildings, so as to meet the needs of building users. At the same time, the operation mode and management means of construction equipment can be optimized to reduce the operation of all kinds of equipment, to maintain the cost of expenditure, and to reduce the energy consumption caused by improper use. Building automatic control system relates to all aspects of building equipment, and is closely related to the user's perception of use. Building automation system is the most extensive in intelligent building, involving the most types of equipment, and the largest design workload. The construction needs to coordinate the workload and the most heavy part of the construction work. To a great extent, the functions of the intelligent building depend on the design quality of the building automatic control system, the completion quality and the completion level of the construction work. On the basis of explaining the development history of intelligent building (IB) and building automatic control system (BAS), the main composition, system function and realization mode of building automatic control system, the paper introduces the following aspects: 1. The design and implementation of the building automation system of Gansu Mobile production scheduling Building are emphasized. The construction scheme of "centralized management and decentralized control" is designed and put forward. The distributed control system, (DCS), direct digital controller (DDC), is used to realize the system. The work accomplished is mainly reflected in the following aspects: (1) the requirements of building automatic control system in Gansu Mobile production and dispatching Building are analyzed. The refrigeration station equipment, air conditioning equipment and fresh air equipment are mainly completed. The monitoring subsystem of water supply and sewerage equipment and the monitoring subsystem of transformer and distribution equipment need to monitor the quantity of equipment and the number of signals of each type. (2) according to the actual project demand, the design scheme of the system is put forward, and the overall design of the system is put forward. In the aspects of subsystem design, equipment hardware configuration, control flow of each subsystem, the building automation system is designed and implemented. (3) the complete whole system is designed and implemented from system landing, equipment condition monitoring, equipment remote starting and stopping control, etc. Fault equipment alarm, interface system equipment monitoring and other aspects are tested and analyzed. The results show that the system functions and various technical performance indexes can meet the design requirements. (4) taking the energy-saving strategy of "the advance shutdown of water cooling units to use the residual cooling capacity of refrigerated water in the pipeline" as an example, The energy saving effect of building automation control system is analyzed, and the energy saving ratio reaches 7.5.
