Intelligent building energy management system based on technology of internet of things

Abstract

The invention relates to the technical field of energy management, and particularly relates to an intelligent building energy management system based on a technology of the internet of things. The intelligent building energy management system comprises an energy monitoring sub-system, an energy analysis sub-system, an energy metering management sub-system, and a client query control sub-system, wherein the energy monitoring sub-system monitors and controls a working state of energy equipment in real time; the energy analysis sub-system receives, detects and analyzes data; the energy metering management sub-system processes and manages the data; and the client query control sub-system can perform corresponding energy data query and control on related energy equipment for a user. The intelligent building energy management system is non-destructive, intelligent and easy to use, and hardly affects the existing working environment in the deployment process; a plurality of lessees in a building can be supported; each lessee can control a respective area in a building, and can dynamically carry out intelligent analysis according to the factors such as environments, user-defined modes, and parameters; the interaction of a networked sensor and energy equipment is determined; and the targets of saving energy and reducing emission is achieved under the condition of not reducing the environmental comfort level are also achieved.

Description

[technical field] [0001] The invention relates to the technical field of energy management, in particular to an intelligent building energy management system based on Internet of Things technology. [Background technique] [0002] Market trends indicate that global energy demand will increase by as much as 57% over the next 25 years. Asia is expected to account for 56% of the world's total energy consumption by 2030. Energy costs will continue to rise, so smart energy management for commercial buildings is important for businesses to remain competitive in the future. [0003] New buildings can be designed thoroughly using today's energy conservation and management methods, but most buildings were built in an era when energy was cheap and conservation was not an issue. These old buildings are designed to meet extreme conditions such as the hottest or coldest days of the year to have a comfortable environment. However, at most other times, only part of the system is loaded. ...

Problems solved by technology

Retrofitting existing buildings for energy efficiency must not be time-consuming, expensive, or a hindrance to existing tenants

A number of technical problems are often encountered when effectively managing a building's air conditioning equipment: many HVAC systems produce a constant air volume, for example, regardless of load or temperature, and many building management systems simply turn fans off or on at specific times, resulting in Temperature control issues and energy waste

[0007] In existing solutions, GPRS (General Packet Radio Service technology, which is a mobile data service available to mobile phone users) is mostly used at the equipment layer. 1. There may be blind spots in the monitoring link, (such as in existing buildings, Generally underground, mobile phone signals are generally poor, and there are no signals at all in some corners), so the monitored data may be inaccurate; 2. All transmitted data needs to be transmitted through the base station of the telecom operator. During the peak period, the phenomenon of data loss is relatively serious, and the performance is relatively poor. If it is found that the base station processing performance of the operator has a bottleneck, the possibility of relying on the telecom operator to solve it is relatively small; 3. It is precisely because data transmission is heavily dependent on the telecom operator, so There is a large delay in the monitoring and control of equipment energy consumption; 4. Each transmission point is relatively isolated. If a certain transmission point is broken, it may affect a piece of equipment, and it may lose control of a piece of equipment. ;5. To use GPRS communication, it needs to occupy the resources of telecom operators, and needs to pay money to telecom operators every year, relatively speaking, the cost is relatively high
