0.背景 background
我国建设部提出，经过大数据统计分析，2020年底，全国建筑总面积已经超过400亿平方米，建筑能耗将达到十点九亿吨标准煤，建筑在建造和使用过程中直接消耗的能源已占全社会总能耗的百分之三十左右。我国当前大型公共建筑能耗在计量、传输、节能监管层次存在一定问题，粗放式能耗管理在一定程度会造成大量的能耗浪费，大型公共建筑能耗监测与节能管理已经成为我国节能减耗工作的重心。虽然我国当前已经开展了信息化能好监管工作，但是很多地方因为数据采集自动化程度较低，管理信息化程度较低，在数据上报的过程中，存在诸多问题，直接增加了能耗数据统计的难度。为了实现能耗数据信息采集，对能源消耗情况进行动态化管控，本文将针对大型公共建筑能耗监控系统进行详细分析。
China's Ministry of construction has proposed that through the statistical analysis of big data, by the end of 2020, the total construction area of the country has exceeded 40 billion square meters, and the building energy consumption will reach 1.09 billion tons of standard coal. The energy directly consumed by buildings in the process of construction and use has accounted for about 30% of the total energy consumption of the whole society. At present, there are some problems in the measurement, transmission and energy-saving supervision of energy consumption of large public buildings in China. Extensive energy consumption management will cause a lot of energy consumption waste to a certain extent. Energy consumption monitoring and energy-saving management of large public buildings have become the focus of energy conservation and consumption reduction in China. Although China has carried out the supervision of informatization, there are many problems of concealment in the process of data reporting, which directly increases the difficulty of energy consumption data statistics because of the low degree of automation of data collection and low degree of management informatization. In order to achieve accurate energy consumption data collection and effective dynamic control of energy consumption, this paper will analyze the energy consumption monitoring system of large public buildings in detail.
1. 国内外大型公共建筑能耗监控系统发展 development of energy consumption monitoring system for large public buildings at home and abroad
放眼国外来看，国外的智能楼宇技术已经较为成熟，能耗数据信息监测的智能化、自动化水平也相对较高。针对发达国家来说，尤其是针对大型公共建筑的能耗监控是相当注重的，智能化能耗监测设备也不断完善，工程系统运行稳定。针对我国来说，智能楼宇技术虽然有所运用，但是缺乏系统化的智能楼宇集成系统，相关观念、理念并未形成，与国外仍然存在较大差距。我国很多智能楼宇系统在运行的过程中，缺乏相关系统整体运行机制，会造成事半功倍问题，导致投资浪费，智能楼宇监测系的实时性、可靠性、稳定性都很难达到世界标准水平。国外当前很多信息化技术企业都已经针对大型公共建筑能耗监控系统，研发出了与其相匹配的系统性产品，美国霍尼韦尔、美国江森自控、德国西门子等公司，都进行了能耗监测系统产品研发，促使国家大型公共建筑能耗监控系统运行更加稳定。我国智能楼宇发展虽然存在不完善之处，但是在国家和企业的共同努力推动之下，正在发展。我国上海元上能耗计量管理系统、研华地BEMS楼宇能源管理系统，都展现出了自身独特的价值，在我国大型公共建筑能耗监控工作当中运用广泛。
Looking abroad, foreign intelligent building technology has been relatively mature, and the intelligent and automatic level of energy consumption data and information monitoring is also relatively high. For developed countries, especially for large public buildings, great attention is paid to energy consumption monitoring, intelligent energy consumption monitoring equipment is constantly improved, and the engineering system operates stably. For China, although intelligent building technology has been applied, it lacks systematic intelligent building integration system, relevant concepts and ideas have not been formed, and there is still a large gap with foreign countries. During the operation of many intelligent building systems in China, the lack of overall operation mechanism of relevant systems will lead to the problem of twice the result with half the effort, resulting in a waste of investment. The real-time, reliability and stability of intelligent building monitoring system are difficult to reach the world standard level. At present, many foreign information technology enterprises have developed matching systematic products for the energy consumption monitoring system of large public buildings. American Honeywell, American Johnson Controls, German Siemens and other companies have actively carried out the research and development of energy consumption monitoring system products, so as to promote the operation of energy consumption monitoring system of national large public buildings to be more stable and efficient. Although there are imperfections in the development of intelligent buildings in China, they are actively developing under the joint efforts of the state and enterprises. China's Shanghai Yuanshang energy consumption measurement and management system and Advantech BEMS building energy management system all show their unique value and are widely used in the energy consumption monitoring of large public buildings in China.
2大型公共建筑能耗监控数据采集 Energy consumption monitoring data collection of large public buildings
2.1能耗监控数据采集 energy consumption monitoring data collection
大型公共建筑能耗数内部数据系统繁杂，并且耗能的单位较多，为了做好大型公共建筑能耗监控系统构架，要对大型公共建筑能耗监控数据信息内容进行把控。结合我国颁布的《国家机关办公建筑和大型公共建筑的具体内容》当中的要求来看，大型公共建筑能耗数据信息监控内容如图1所示。
The internal data system of energy consumption of large public buildings is complex, and there are many energy consuming units. In order to do a good job in the framework of energy consumption monitoring system of large public buildings, it is necessary to control the content of energy consumption monitoring data of large public buildings. According to the requirements in the specific contents of state organ office buildings and large public buildings issued by China, the monitoring content of energy consumption data information of large public buildings is shown in Figure 1.

2.2能耗监控数据处理 energy consumption monitoring data processing
在开展大型公共建筑能耗监测的过程中，可以借助一般性检验计量装置对能耗数据信息进行检测，在明确能耗计量装置峰值和谷值的基础上，对各项数据进行监控。针对电能表当中的功率情况进行验证。为了保障数据信息采集，可以连续两次进行数据信息采集，对两次数据信息采集误差进行把控，确保功率低于之路能耗设备功率的2倍。在确保数据信息采集的基础上，还需要开展分项能耗数据计算，借助计量装置开展检测，结合各项能耗指标的计算方法，保障计量检测水平。
In the process of energy consumption monitoring of large public buildings, the energy consumption data information can be detected with the help of general inspection and metering devices, and various data can be monitored on the basis of clarifying the peak and valley values of energy consumption metering devices. Verify the power in the watt hour meter. In order to ensure the effectiveness of data and information collection, data and information collection can be carried out twice in a row, and the errors of the two data and information collection can be controlled to ensure that the power is less than twice the peak power of the energy consuming equipment on the road. On the basis of ensuring the accuracy of data information collection, it is also necessary to carry out sub item energy consumption data calculation, carry out detection with the help of metering devices, and ensure the measurement and detection level in combination with the calculation method of various energy consumption indicators.

For the application layer, it covers four levels: data and information management, analysis and display, information service and background management. Many words are covered in different levels. The function of the application layer in the energy consumption monitoring of large public buildings is used for energy consumption data information processing, display and data information monitoring. In the application layer, each function can be regarded as an independent system module.

The energy consumption monitoring of large public buildings is generally controlled and managed with the help of software app. The energy consumption monitoring system software of large public buildings mentioned in this paper covers monitoring terminal, database, data management system, data acquisition system, firewall, communication network, concentrator and building data information acquisition terminal. The energy consumption data information collected by the intelligent building system will be transmitted to the data concentrator for centralized processing of energy consumption data information and operation status such as electric energy meter, water meter, cooling meter and gas meter in the building. The concentrator will convert the data information into TCP / IP protocol packets. Under the action of firewall, the communication network will promote the operation of data information processing module and transmit the relevant energy consumption data information to the database. The data acquisition system manages the building terminal communication protocol in the concentrator and checks the errors in data communication regularly. Conduct relevant data processing for many contents such as data loss and abnormal work, effectively obtain relevant data information in the database, and dynamically monitor, evaluate, analyze, store and display the energy consumption in the building in combination with the energy consumption monitoring indicators set by the system. The monitoring terminal will generally obtain relevant data from the database and obtain the evaluation results for comprehensive analysis and control. The monitoring terminal will analyze the control instructions in combination with the database, data acquisition system, communication network, firewall, concentrator, etc., so as to control the data information status of the acquisition terminal of the building.

In the energy consumption monitoring system of large public buildings, one of the key technologies is a variety of energy consumption acquisition terminal access technology, so as to integrate and collect a variety of energy consumption in public buildings. There are different access technologies of multiple energy consumption acquisition terminals in different brands of energy consumption monitoring systems. How to connect multiple energy consumption acquisition terminals with one concentrator is very important. Because there are private protocols for different energy consumption monitoring systems, when selecting the energy consumption monitoring system of large public buildings, we should analyze the systems of different brands, clarify the private protocols and energy consumption collection and connection modes of each brand, and ensure that the energy consumption monitoring system developed by different brands can meet the actual use needs of large public buildings, Ensure that the software system can be smoothly connected to different energy consumption acquisition terminals.
