The invention discloses a building energy management system based on cloud services, relates to the technical field of energy management, and solves the technical problem of reducing the energy consumption. The system comprises a parameter perception layer consisting of an energy consumption acquiring device, an electric interface device and an environment monitoring device, a data transmission layer consisting of an Ethernet network, a gateway and a network interface module, a cloud service layer consisting of a cloud storage server group and a cloud computing server group, and a client terminal layer consisting of a plurality of client terminals, wherein the data transmission layer is responsible for the transmission of data; all appliances and devices of the parameter perception layer are respectively accessed in the data transmission layer for acquiring energy consumption data of energy consumption objects and environmental data of environmental objects and receiving electric parameters output by electric objects; all servers in the cloud service layer and all client terminals in the client terminal layer are accessed in the data transmission layer. The system, provided by the invention, can help users to master the energy use rules, discover the energy-saving potential and find out the energy consumption loopholes.

Description

technical field [0001] The invention relates to energy management technology, in particular to a cloud service-based building energy management system technology. Background technique [0002] Facing the grim situation of energy shortage, developed countries that have gone through the extensive development of industrialization for more than half a century first realized the seriousness of energy shortage, and then continued to use information technology to improve energy management. The United States, Germany, Japan, Denmark, Norway, France, the United Kingdom and other countries began to study and apply energy management systems in the 1960s, and achieved good results. [0003] In the United States, more than 50% of buildings with an area of ​​more than 100,000 square feet have energy management systems, which is equivalent to 1 / 3 of all commercial buildings in the United States. The experience of the United States shows that the adoption of energy management systems can s...

AI Technical Summary

Problems solved by technology

However, most of these cloud computing research plans mainly consider issues from the perspective of business model and infrastructure. From the perspective of application, they can make full use of the advantages of cloud computing and provide on-demand services and automatically scalable applications. rarely seen

Especially in the fields of energy management, energy saving and consumption reduction, and green and low-carbon fields, there are no case reports of successful applications

[0011] However, compared with the wider and more urgent needs of the current society for building energy management, based on the current situation at home and abroad, there are still some deficiencies in the further promotion and application of building energy management systems, which need the support of a more complete technical system and promotion of industrialization

[0012] First of all, the functions of domestic building energy management systems basically stay at the level of "energy consumption monitoring". The system only collects building energy consumption data, but does not collect other factors that affect energy consumption, such as indoor temperature, air conditioning system Various operating parameters, the opening degree of the lighting system, etc., make the overall analysis ability of the system insufficient, and cannot quickly find out where the energy leak is, so that the "management" function of the system cannot be fully utilized

[0013] Second, the existing energy management system is difficult to interface with the building control system (in fact, the building control system should become a subsystem of the energy management system), which makes the two systems independent of each other and cannot share information, making " The closed-loop process of data monitoring-analysis diagnosis-control execution" cannot complete the closed loop

[0014] Third, it does not have the capabilities of multi-user, massive data, and distributed processing, and is only suitable for single buildings and small-scale applications

[0015] Fourth, the existing energy management system has a weak ability to analyze and process data, and mainly uses some comparative analysis methods, such as horizontal comparison, composition ratio, chain ratio, etc.

Lack of some automated and intelligent data analysis and mining modules

[0016] Fifth, there is almost no concept of "management" in the domestic treatment of building energy consumption. It is just some simple start-up and stop operations and maintenance of building equipment by property personnel. Buildings are also hard to run in an optimal way

[0017] Sixth, the hardware and software products of various manufacturers differ greatly in function, performance and interface mode, and are not interchangeable. Therefore, there has not been a very mature, perfect and widely recognized integrated solution in China so far.

[0018] At present, the research and systems in the field of building energy management are very scarce, so that many buildings do not know how energy is consumed, whether the equipment is running efficiently, lack the concept and ability of "system energy saving", and even have made some energy-saving renovations, and there is a Energy saving in one place leads to energy consumption in other places, and finally the overall energy consumption increases instead.
