??0.背景 background

??我國建設部提出,經過大數據統計分析,2020年底,全國建筑總面積已經超過400億平方米,建筑能耗將達到十點九億噸標準煤,建筑在建造和使用過程中直接消耗的能源已占全社會總能耗的百分之三十左右。我國當前大型公共建筑能耗在計量、傳輸、節能監管層次存在一定問題,粗放式能耗管理在一定程度會造成大量的能耗浪費,大型公共建筑能耗監測與節能管理已經成為我國節能減耗工作的重心。雖然我國當前已經開展了信息化能好監管工作,但是很多地方因為數據采集自動化程度較低,管理信息化程度較低,在數據上報的過程中,存在諸多問題,直接增加了能耗數據統計的難度。為了實現能耗數據信息采集,對能源消耗情況進行動態化管控,本文將針對大型公共建筑能耗監控系統進行詳細分析。

??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. 國內外大型公共建筑能耗監控系統發展 development of energy consumption monitoring system for large public buildings at home and abroad

??放眼國外來看,國外的智能樓宇技術已經較為成熟,能耗數據信息監測的智能化、自動化水平也相對較高。針對發達國家來說,尤其是針對大型公共建筑的能耗監控是相當注重的,智能化能耗監測設備也不斷完善,工程系統運行穩定。針對我國來說,智能樓宇技術雖然有所運用,但是缺乏系統化的智能樓宇集成系統,相關觀念、理念并未形成,與國外仍然存在較大差距。我國很多智能樓宇系統在運行的過程中,缺乏相關系統整體運行機制,會造成事半功倍問題,導致投資浪費,智能樓宇監測系的實時性、可靠性、穩定性都很難達到世界標準水平。國外當前很多信息化技術企業都已經針對大型公共建筑能耗監控系統,研發出了與其相匹配的系統性產品,美國霍尼韋爾、美國江森自控、德國西門子等公司,都進行了能耗監測系統產品研發,促使國家大型公共建筑能耗監控系統運行更加穩定。我國智能樓宇發展雖然存在不完善之處,但是在國家和企業的共同努力推動之下,正在發展。我國上海元上能耗計量管理系統、研華地BEMS樓宇能源管理系統,都展現出了自身*的價值,在我國大型公共建筑能耗監控工作當中運用廣泛。

??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大型公共建筑能耗監控數據采集 Energy consumption monitoring data collection of large public buildings

??2.1能耗監控數據采集 energy consumption monitoring data collection

??大型公共建筑能耗數內部數據系統繁雜,并且耗能的單位較多,為了做好大型公共建筑能耗監控系統構架,要對大型公共建筑能耗監控數據信息內容進行把控。結合我國頒布的《國家機關辦公建筑和大型公共建筑的具體內容》當中的要求來看,大型公共建筑能耗數據信息監控內容如圖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.

Figure 1 energy consumption monitoring data collection content

??2.2能耗監控數據處理 energy consumption monitoring data processing

??在開展大型公共建筑能耗監測的過程中,可以借助一般性檢驗計量裝置對能耗數據信息進行檢測,在明確能耗計量裝置峰值和谷值的基礎上,對各項數據進行監控。針對電能表當中的功率情況進行驗證。為了保障數據信息采集,可以連續兩次進行數據信息采集,對兩次數據信息采集誤差進行把控,確保功率低于之路能耗設備功率的2倍。在確保數據信息采集的基礎上,還需要開展分項能耗數據計算,借助計量裝置開展檢測,結合各項能耗指標的計算方法,保障計量檢測水平。

??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.

??3.1系統框架 system framework

??本文當中所研究的大型公共建筑能耗監控系統,緊密依照《國家機關辦公建筑和大型公共建筑能耗監測系統——軟件開發指導說明書》當中的要求開展設計的,切實滿足了我國規定的設計標準。大型公共建筑能耗監控系統框架搭建模式如圖2所示,其主要目的便是獲取采集器前端數據信息。針對信息資源與數據層來說,便是在大型公共建筑當中,實現能源消耗的數據信息獲取、傳輸,將采集到的能耗數據信息進行分類。針對應用層來說,涵蓋了數據及信息管理、分析展示、信息服務、后臺管理等四個層次內容,不同層次當中涵蓋了諸多字內容。應用層在大型公共建筑能耗監控工作當中的功能,便是用于能耗數據信息處理、展示、數據信息監測。在應用層當中,可以將每個功能當成獨立的系統模塊,在設計應用層模塊時,應該保障每個處理模塊相對獨立,減少各個模塊之間的相互干擾,為后續能耗數據信息處理做鋪墊。針對表現層來說,便是對社會當中不同角色可以結合自身的實際需求,對大型公共建筑能耗數據信息進行分析。

??The energy consumption monitoring system of large-scale public buildings studied in this paper is designed in close accordance with the requirements of "energy consumption monitoring system of state organ office buildings and large-scale public buildings - software development guidance manual", which effectively meets the design standards specified in our country. The framework construction mode of energy consumption monitoring system for large public buildings is shown in Figure 2. Its main purpose is to obtain the front-end data information of the collector. For the information resources and data layer, it is to achieve the acquisition and transmission of first-hand energy consumption data information in large public buildings, and classify the collected energy consumption data information. 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. When designing the application layer module, each processing module should be relatively independent to reduce the mutual interference between each module and pave the way for the subsequent energy consumption data information processing. For the performance layer, it is to analyze the energy consumption data information of large-scale public buildings for different roles in the society in combination with their own actual needs.

??3.2軟件構架 software architecture

??大型公共建筑能耗監控工作一般是借助軟件APP進行操控管理的,在本文當中所提及到的大型公共建筑能耗監控系統軟件當中,涵蓋了監控終端、數據庫、數據管理系統、數據采集系統、防火墻、通信網絡、集中器、樓宇數據信息采集終端。智能樓宇系統所采集到的能耗數據信息,會傳輸到數據集中器當中,將建筑物當中電能表、水表、冷量表、氣表等能耗數據信息、運行狀態進行集中處理。集中器會將數據信息轉換成TCP/IP協議數據包等,通信網絡在防火墻的作用之下,促使數據信息處理模塊運行,將有關的能耗數據信息傳輸到數據庫當中。數據信息采集系統對集中器當中的樓宇終端通信協議進行管理,定時對數據通信存在的錯誤進行查錯。針對數據丟失、工作異常等諸多內容進行相關數據處理,獲取數據庫當中的相關數據信息,結合系統設置的能耗監測指標,動態化對建筑物當中的能耗情況進行監控、測評、分析、存儲、展示。監控終端一般會從數據庫當中獲取相關數據并且得出評估結果,對其進行綜合分析把控。監控終端會結合數據庫、數據采集系統、通信網絡、防火墻、集中器等,對控制指令進行分析,以便于對樓宇的采集終端數據信息狀態把控。

??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.

??在大型公共建筑能耗監控系統當中,關鍵的技術之一便是多種能耗采集終端接入技術,以便于對公共建筑當中的多種能耗進行整合采集。不同品牌能耗監控系統當中的多種能耗采集終端接入技術存在不同差異,如何借助一個集中器進行多種能耗采集連接至關重要。因為不同能耗監控系統存在私有協議,所以在選擇大型公共建筑能耗監控系統時,應該對不同品牌的系統進行分析,明確各個品牌的私有協議、種能耗采集連接方式,保障不同品牌開發的能耗監控系統滿足大型公共建筑的實際使用需求,確保軟件系統可以順利接入到不同能耗采集終端當中。

??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.

??4.2系統軟件開發技術system software development technology

??在實際開展大型公共建筑能耗監控系統運用時,需要結合系統的整體框架和模塊分層特點,引入本軟件平臺的開發技術。借助Java、JavaScrip等編程語言進行程序編碼設計,將數據存儲庫與云存儲技術相銜接,確保能耗數據信息存儲的安全性與巨型容量。在進行數據信息傳輸通訊時,應該選擇穩定的RS485數據通信標準,保障存儲數據信息高質量運行。

??In the actual application of large-scale public building energy consumption monitoring system, it is necessary to introduce the development technology of this software platform in combination with the overall framework and module layered characteristics of the system. With the help of Java, javascrip and other programming languages for program coding design, the data repository is connected with cloud storage technology to ensure the security and huge capacity of energy consumption data information storage. During data information transmission and communication, a stable RS485 data communication standard should be selected to ensure the high-quality operation of stored data information.
