Description

Technical Field

[0001] The utility model relates to the technical field of heat load measurement, and particularly relates to an energy-saving and carbon-reducing accounting device based on building heat load measurement. Background Technique

[0002] The heat load of a building refers to the amount of heat that needs to be supplied to the indoor by heating equipment to maintain a certain indoor temperature under specific conditions (such as in winter). It is the main basis for heating design and is usually expressed as the energy consumption per unit area per unit time. Heat load measurement refers to calculating the amount of heat that needs to be supplied to the indoor by heating equipment to maintain a certain indoor temperature under this condition. The energy-saving and carbon-reducing accounting in building heat load measurement mainly refers to quantitatively analyzing the energy consumption and carbon emissions while evaluating the building heat load, and exploring the potential and measures for energy conservation and emission reduction. This accounting process aims to promote the sustainable development of the building industry, reduce energy consumption and environmental pollution, and achieve the goal of green and low-carbon development. The accounting principle is: it is necessary to accurately account for the energy consumption of the building under different working conditions, including the energy consumption of various systems such as heating, ventilation, air conditioning, and lighting. This is usually achieved by installing energy consumption monitoring equipment, collecting energy consumption data, and conducting statistical analysis. Carbon emission accounting: Based on the energy consumption data, combined with the carbon emission factors of various energy sources (i.e., the carbon emissions generated per unit energy usage), calculate the total carbon emissions of the building. Carbon emission factors are usually released by national or industry institutions and are updated according to the latest scientific research.

[0003] According to the above principle, it can be known that the energy-saving and carbon-reducing accounting device mainly includes two major parts: data collection and data analysis. The traditional energy-saving and carbon-reducing accounting device needs to be connected to various sensors inside and outside the building, and most of the sensors are still traditional wired sensors. This leads to the traditional device needing to connect a large number of data lines and being easily affected by the installation location of the sensors, resulting in the device being not flexible enough to use, and the large number of lines will also increase the operation difficulty.

[0021] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Such as Figure 1 , an energy-saving and carbon-reducing accounting device based on building heat load measurement, includes a host terminal 1 and a plurality of data acquisition ends 5. The data acquisition ends 5 are detachably installed on the host terminal 1. The host terminal 1 is built-in with an accounting model, and each heat load measurement data sent by the data acquisition end 5 is accounted through the accounting model. This application uses the accounting model built-in in the host terminal to process and analyze the heat load data collected by the data acquisition end 5, and finally obtains the accounting result. And the energy-saving and carbon-reducing accounting models on the market are relatively mature at present. For example, using energy consumption data and carbon emission factors to quantitatively analyze the carbon emissions of buildings, and this application does not aim to protect the accounting model itself, so the principle of the accounting model will not be elaborated too much here. Since the data acquisition end 5 and the host terminal 1 are detachable, when the data acquisition end accesses the data of the sensor, it can be removed from the host terminal 1 for data connection.

[0023] Such as Figure 4As shown, the host terminal 1 is also built-in with a Bluetooth receiving module, and the data acquisition end 5 is built-in with a Bluetooth transmitting module. Data transmission between the data acquisition end 5 and the host terminal 1 is achieved through Bluetooth wireless transmission. The data acquisition end 5 can be separated from the host terminal 1. Therefore, by using the Bluetooth wireless transmission method, data can be effectively sent even after the data acquisition end 5 is separated. Using this method, there is no need to consider the distance between sensors and the wiring method of sensors. Whether the sensors are wired or wireless, they are first connected to the data acquisition end 5, and then the data acquisition end 5 wirelessly sends the data to the host terminal 1, reducing the wiring difficulty. Moreover, when using it, there is no need to consider the length of the line, and the operation is more flexible.

[0024] As Figure 2 and Figure 4 shown, the data acquisition end 5 is provided with a first communication port 10, a second communication port 11, and a third communication port 12. The first communication port 10, the second communication port 11, and the third communication port 12 are electrically connected to the communication module a, the communication module b, and the communication module c built-in in the data acquisition end 5 in sequence. The data acquisition end 5 uses multiple communication ports, which is suitable for the access of different types of sensors. Since the communication protocols adopted by various sensors are different, the data acquisition end 5 is also built-in with a module that can decode different protocols to ensure stable data transmission.

[0025] Regarding the detachable design of the data acquisition end 5, as Figure 1 and Figure 3 shown, the host terminal 1 includes a housing 2. A storage groove 13 is installed on the housing 2. The data acquisition end 5 is installed inside the storage groove 13. A protective cover 6 is hinged to the top of the storage groove 13. The storage groove 13 can be used to store the data acquisition end 5 when it is not in use, avoiding the loss of the data acquisition end 5. The data acquisition end 5 includes a connector 7. A slot 8 is provided on the surface of the connector 7. A plug post 14 is provided on the inner wall of the storage groove 13. The slot 8 and the plug post 14 are movably inserted. The data acquisition end 5 is installed in the storage groove 13 in the form of the slot 8 being inserted into the plug post 14, with a firm installation. And the presence of the protective cover 6 can prevent the data acquisition end 5 from being lost during carrying and can also play a certain role in dust prevention and protection.

[0026] The modules of the data acquisition end 5 all need electric energy for power supply, so the charging problem is involved. As Figure 2 and Figure 3As shown, a positive electrode contact 16 is installed on the insertion post 14, a negative electrode contact 9 is provided on the slot 8, the data acquisition terminal 5 is also internally provided with a power supply module, the negative electrode contact 9 is electrically connected to the power supply module, and the data acquisition terminal 5 adopts a contact charging method. When not in use, it can prevent automatic charging in the storage slot 13, so there is no need to worry about power feed problems. A display screen 3 and a key panel 4 are installed on the housing 2. The host terminal 1 is internally provided with an I / O drive module, and the display screen 3 and the key panel 4 are electrically connected to the I / O drive module. The display screen 3 is used to display information such as results, and the key panel 4 is used to conveniently control the host terminal 1.
