[0004] However, in the prior art, it is not possible to accurately analyze the actual carbon emissions of a building during the construction process, resulting in a low carbon neutrality efficiency of the constructed building. Summary of the invention

[0005] To this end, the present invention provides a carbon neutrality emission management system based on building construction, which is used to overcome the problem in the prior art that it is impossible to accurately analyze the actual carbon emission emissions of the building during the construction process, resulting in low carbon neutrality efficiency of the construction building.

[0006] To achieve the above objectives, the present invention provides a carbon neutral emission management system based on building construction, comprising:

[0007] A carbon emission management module, used to obtain carbon emission information of building materials and calculate the carbon emission amount of building materials according to the carbon emission information;

[0008] A construction management module to calculate the carbon emissions of construction equipment;

[0009] A summary module, which is connected to the carbon emission management module and the construction management module respectively, and is used to calculate the total carbon emissions of the current building;

[0010] A setting module, which is connected to the summary module and includes a calculation unit and a carbon fixation unit connected to each other;

[0011] The calculation unit is used to calculate the carbon emission index of the current building according to the total carbon emission of the building on the current construction day, and output the comparison result of the carbon emission index with the preset carbon emission comparison index to the carbon sequestration unit;

[0012] The carbon fixation unit determines a carbon fixation mode according to an output result of the calculation unit, wherein the carbon fixation mode includes greening carbon fixation at a set speed and reaction carbon fixation at a set speed;

[0013] When the carbon fixation mode is determined to be greening carbon fixation, the carbon fixation unit calculates the greening speed determination parameter according to the carbon emission index and the carbon emission comparison index to determine the greening speed; when the carbon fixation mode is determined to be reaction carbon fixation, the carbon fixation unit calculates the reaction rate determination parameter according to the carbon emission index and the carbon emission comparison index to determine the carbon neutralization reaction rate.

[0014] Further, the carbon emission management module includes a building material unit and a carbon emission calculation unit;

[0015] The building material unit is used to count the types of building materials used in construction, the actual usage amount of each building material, and the carbon emission information of the building materials;

[0016] The carbon emission calculation unit is connected to the building material unit and is used to calculate the carbon emission of the building materials based on the carbon emission information of the building materials.

[0017] Furthermore, the construction management module is specifically used to count the types of construction equipment, the number of each type of construction equipment, and calculate the average daily carbon emissions of the construction equipment.

[0018] Furthermore, the calculation unit calculates the carbon emission index of the building according to the following formula, setting:

[0019]

[0020] Where S is the carbon emission index, N(i) is the total carbon emission of the building on the i-th construction day, N(i-1) is the total carbon emission of the building on the i-1-th construction day, n is the number of construction days, and i is a positive integer greater than 1.

[0021] Furthermore, a carbon emission comparison index is preset in the calculation unit. If the carbon emission index is less than or equal to the carbon emission comparison index, the output result is o. If the carbon emission index is greater than the carbon emission comparison index, the output result is i. The calculation unit sends the output result to the carbon fixation unit.

[0022] Furthermore, the carbon fixation unit determines the carbon fixation mode according to the output result of the calculation unit, including:

[0023] If the output result is o, the carbon fixation unit sets the carbon fixation mode to greening carbon fixation;

[0024] If the output result is i, the carbon fixation unit sets the carbon fixation mode to reaction carbon fixation.

[0025] Furthermore, when the carbon fixation mode is greening carbon fixation, the carbon fixation unit calculates a greening speed determination parameter, and determines the greening speed based on the greening speed determination parameter;

[0026] The greening speed determination parameter is the difference between the carbon emission index and the carbon emission comparison index.

[0027] Further, the carbon fixation unit calculates a reaction rate determination parameter when the carbon fixation mode is reaction carbon fixation, and determines the carbon neutralization reaction rate based on the reaction rate determination parameter;

[0028] The reaction rate determination parameter is the difference between the carbon emission index and the carbon emission comparison index.

[0029] Furthermore, the total carbon emissions of a building on any construction day are the sum of the carbon emissions of the building materials used on that day and the carbon emissions of the construction equipment on that day.

[0030] Furthermore, it also includes a display device for displaying carbon emissions and carbon neutrality in real time.

[0031] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention realizes comprehensive management of the carbon emission sources of construction buildings by managing carbon emissions of construction buildings, including carbon emissions of construction materials and carbon emissions of construction equipment, and manages the carbon emissions of construction buildings in real time by setting two carbon fixation modes, thereby controlling the carbon emissions of construction buildings and improving the carbon neutrality efficiency of construction buildings.

[0032] Furthermore, the present invention calculates the carbon emissions of construction raw materials by acquiring the carbon emission information of construction raw materials, thereby obtaining the real and effective carbon emissions of the construction building, avoiding miscalculation and omission of the carbon emissions of the construction building, and indirectly improving the carbon neutrality efficiency of the construction building.

[0033] Furthermore, the present invention calculates the carbon emissions of construction equipment by obtaining the average daily carbon emissions of construction equipment, thereby knowing the real and effective carbon emissions in the construction process, further avoiding miscalculation and omission of carbon emissions, and indirectly improving the carbon neutrality efficiency of construction buildings.

[0034] Furthermore, the present invention introduces the carbon emission index of the building. The carbon emission index is a representative parameter of the growth rate of the total carbon emissions of the building during the construction process. It is used to characterize the growth rate of the total carbon emissions of the building. The larger the carbon emission index, the faster the growth rate of the total carbon emissions of the building. By calculating the carbon emission index and determining the corresponding carbon fixation mode based on the carbon emission index, the carbon neutralization process and carbon neutralization scheme are optimized, the carbon neutralization efficiency of the construction building is improved, and the carbon consumption in the carbon neutralization process is reduced.

[0035] Furthermore, the present invention presets a carbon emission comparison index, and determines a carbon fixation mode according to a comparison result between the carbon emission index and the carbon emission comparison index, wherein the greening carbon fixation mode is environmentally friendly and has a long-lasting carbon fixation effect, but has a low carbon fixation efficiency, and the reaction carbon fixation mode consumes carbon dioxide through chemical reactions and has a high carbon fixation efficiency. When the carbon emission index is less than or equal to the carbon emission comparison index, the greening carbon fixation mode is selected, and when the carbon emission index is greater than the carbon emission comparison index, the reaction carbon fixation mode is selected to improve the carbon neutralization efficiency, and by adopting different carbon fixation modes, the carbon neutralization efficiency of the construction building is improved.

[0036] Furthermore, when the present invention determines that the carbon fixation mode is greening carbon fixation, the greening speed is adjusted to adapt to the total carbon emissions of the construction building, thereby further improving the carbon neutrality efficiency of the construction building.

[0037] Furthermore, when the present invention determines that the carbon fixation mode is reaction carbon fixation, the reaction rate is adjusted to adapt to the total carbon emissions of the construction building, thereby further improving the carbon neutrality efficiency of the construction building.

It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0044] See also Figures 1 to 4 As shown, the carbon neutral emission management system based on building construction of the present invention includes:

[0045] A carbon emission management module, used to obtain carbon emission information of building materials and calculate the carbon emission amount of building materials according to the carbon emission information;

[0046] A construction management module to calculate the carbon emissions of construction equipment;

[0047] A summary module, which is connected to the carbon emission management module and the construction management module respectively, and is used to calculate the total carbon emissions of the current building;

[0048] A setting module, which is connected to the summary module and includes a calculation unit and a carbon fixation unit connected to each other;

[0049] The calculation unit is used to calculate the carbon emission index of the current building according to the total carbon emission of the building on the current construction day, and output the comparison result of the carbon emission index with the preset carbon emission comparison index to the carbon sequestration unit;

[0050] The carbon fixation unit determines a carbon fixation mode according to an output result of the calculation unit, wherein the carbon fixation mode includes greening carbon fixation at a set speed and reaction carbon fixation at a set speed;

[0051] When the carbon fixation mode is determined to be greening carbon fixation, the carbon fixation unit calculates the greening speed determination parameter according to the carbon emission index and the carbon emission comparison index to determine the greening speed; when the carbon fixation mode is determined to be reaction carbon fixation, the carbon fixation unit calculates the reaction rate determination parameter according to the carbon emission index and the carbon emission comparison index to determine the carbon neutralization reaction rate.

[0052] The reaction carbon fixation mode is to consume carbon dioxide through chemical reaction, which is a mature existing technology. The appropriate reaction method and reaction equipment can be selected according to actual needs, and this example is not limited thereto.

[0053] The single type of building raw material may be a single type of prefabricated component for construction, or a single type of building material, which is set according to actual conditions and is not specifically limited in this embodiment.

[0054] The present invention achieves comprehensive management of the source of carbon emissions from construction buildings by managing carbon emissions from construction buildings, including carbon emissions from building materials and carbon emissions from construction equipment. It also manages carbon emissions from construction buildings in real time by setting two carbon fixation modes, thereby controlling the carbon emissions from construction buildings and improving the carbon neutrality efficiency of construction buildings.

[0055] Specifically, the carbon emission management module includes a building material unit and a carbon emission calculation unit;

[0056] The building material unit is used to count the types of building materials used in construction, the actual usage amount of each building material, and the carbon emission information of the building materials;

[0057] The carbon emission calculation unit is connected to the building material unit and is used to calculate the carbon emission of the building materials based on the carbon emission information of the building materials.

[0058] The present invention calculates the carbon emissions of construction raw materials by acquiring the carbon emission information of construction raw materials, thereby obtaining the real and effective carbon emissions of the construction building, avoiding miscalculation and omission of the carbon emissions of the construction building, and indirectly improving the carbon neutrality efficiency of the construction building.

[0059] Among them, the carbon emission information of building materials can be obtained from the production process of building materials or from manufacturers.

[0060] Specifically, the construction management module is used to count the types of construction equipment, the number of each construction equipment, and calculate the average daily carbon emissions of the construction equipment.

[0061] The present invention calculates the carbon emissions of construction equipment by obtaining the average daily carbon emissions of construction equipment, thereby knowing the real and effective carbon emissions in the construction process, further avoiding miscalculation and omission of carbon emissions, and indirectly improving the carbon neutrality efficiency of construction buildings.

[0062] The calculation method for the average daily carbon emissions of construction equipment is: carbon emissions (tCO2e) = emission factor (tCO2e / t) × actual emissions (t). The emission factor refers to the amount of carbon dioxide produced when a unit of fuel or energy is burned. For example, the emission factor of coal is 2.93t CO2e / t, and that of diesel is 3.15t CO2e / t; while the actual emissions refer to the total amount of fuel or energy actually consumed.

[0063] Specifically, the calculation unit calculates the carbon emission index of the building according to the following formula, setting:

[0064]

[0065] Where S is the carbon emission index, N(i) is the total carbon emission of the building on the i-th construction day, N(i-1) is the total carbon emission of the building on the i-1-th construction day, n is the number of construction days, and i is a positive integer greater than 1.

[0066] The present invention introduces a carbon emission index of a building. The carbon emission index is a representative parameter of the growth rate of the total carbon emissions of the building during the construction process. It is used to characterize the growth rate of the total carbon emissions of the building. The larger the carbon emission index, the faster the growth rate of the total carbon emissions of the building. By calculating the carbon emission index and determining the corresponding carbon fixation mode based on the carbon emission index, the carbon neutralization process and carbon neutralization scheme are optimized, the carbon neutralization efficiency of the construction building is improved, and the carbon consumption in the carbon neutralization process is reduced.

[0067] Specifically, a carbon emission comparison index is preset in the calculation unit. If the carbon emission index is less than or equal to the carbon emission comparison index, the output result is o. If the carbon emission index is greater than the carbon emission comparison index, the output result is i. The calculation unit sends the output result to the carbon fixation unit.

[0068] Specifically, the carbon fixation unit determines the carbon fixation mode according to the output result of the calculation unit, including:

[0069] If the output result is o, the carbon fixation unit sets the carbon fixation mode to greening carbon fixation;

[0070] If the output result is i, the carbon fixation unit sets the carbon fixation mode to reaction carbon fixation.

[0071] Specifically, when determining the carbon emission comparison index of this embodiment, at least 2000 carbon emission indices are selected from the historical construction data to construct a carbon emission index data set. The carbon emission index is used as a random variable, and the random variable obeys a probability density function. Then, a normal distribution curve can be constructed according to the probability density function, and the 95% confidence interval of the normal distribution curve is determined. The carbon emission index corresponding to the midpoint of the 95% confidence interval is determined as the carbon emission comparison index. Constructing a probability density function and constructing a normal distribution curve based on the probability density function are commonly used technical means in statistics, which will not be repeated here.

[0072] The present invention presets a carbon emission comparison index, and determines a carbon fixation mode according to a comparison result between the carbon emission index and the carbon emission comparison index, wherein the greening carbon fixation mode is environmentally friendly and has a long-lasting carbon fixation effect, but has a low carbon fixation efficiency, and the reaction carbon fixation mode consumes carbon dioxide through chemical reactions and has a high carbon fixation efficiency. When the carbon emission index is less than or equal to the carbon emission comparison index, the greening carbon fixation mode is selected, and when the carbon emission index is greater than the carbon emission comparison index, the reaction carbon fixation mode is selected to improve the carbon neutralization efficiency. By adopting different carbon fixation modes, the carbon neutralization efficiency of the construction building is improved.

[0073] Specifically, when the carbon fixation mode is greening carbon fixation, the carbon fixation unit calculates a greening speed determination parameter, and determines the greening speed based on the greening speed determination parameter;

[0074] The greening speed determination parameter is the difference between the carbon emission index and the carbon emission comparison index.

[0075] Specifically, the greening speed determination parameter is compared with a preset greening speed comparison parameter to adjust the greening speed to a corresponding value, the preset greening speed comparison parameter includes a first preset greening speed comparison parameter and a second preset greening speed comparison parameter, the first preset greening speed comparison parameter is less than the second preset greening speed comparison parameter, wherein,

[0076] When the greening speed determination parameter is less than or equal to the first preset greening speed comparison parameter, the greening speed is not adjusted, and the greening speed is set to the initial greening speed;

[0077] When the greening speed determination parameter is greater than the first preset greening speed comparison parameter and less than or equal to the second preset greening speed comparison parameter, the first greening speed adjustment coefficient 1.1 is selected to adjust the greening speed to the corresponding value;

[0078] When the greening speed determination parameter is greater than the second preset greening speed comparison parameter, selecting the second greening speed adjustment coefficient 1.2 to adjust the greening speed to the corresponding value;

[0079] The adjusted greening speed is the product of the initial greening speed and the greening speed adjustment coefficient.

[0080] Among them, the initial greening speed is related to the total carbon emissions of the constructed buildings on the first construction day.

[0081] In this embodiment, when the first preset greening speed comparison parameter and the second preset greening speed comparison parameter are set, the greening speed determination parameter is calculated at least 2000 times according to the historical construction data, and a greening speed determination parameter data set is constructed. The greening speed determination parameter is taken as a random variable, and the random variable obeys the probability density function. Then, a normal distribution curve can be constructed according to the probability density function, and the 95% confidence interval of the normal distribution curve is determined. The greening speed determination parameter corresponding to the midpoint of the 95% confidence interval is determined as the first preset greening speed comparison parameter, and the greening speed determination parameter corresponding to the lower limit of the 95% confidence interval is determined as the second preset greening speed comparison parameter.

[0082] When the carbon fixation mode is determined to be greening carbon fixation, the present invention further improves the carbon neutrality efficiency of the construction building by adjusting the greening speed to adapt to the total carbon emissions of the construction building.

[0083] Specifically, the carbon fixation unit calculates a reaction rate determination parameter when the carbon fixation mode is reaction carbon fixation, and determines the carbon neutralization reaction rate based on the reaction rate determination parameter;

[0084] The reaction rate determination parameter is the difference between the carbon emission index and the carbon emission comparison index.

[0085] Specifically, the reaction rate determination parameter is compared with a preset reaction rate comparison parameter to adjust the reaction rate to a corresponding value, the preset reaction rate comparison parameter includes a first preset reaction rate comparison parameter and a second preset reaction rate comparison parameter, the first preset reaction rate comparison parameter is less than the second preset reaction rate comparison parameter, wherein,

[0086] When the reaction rate determination parameter is less than or equal to the first preset reaction rate comparison parameter, the reaction rate is not adjusted and the reaction rate is set to the initial reaction rate;

[0087] When the reaction rate determination parameter is greater than the first preset reaction rate comparison parameter and less than or equal to the second preset reaction rate comparison parameter, selecting the first reaction rate adjustment coefficient 1.2 to adjust the reaction rate to the corresponding value;

[0088] When the reaction rate determination parameter is greater than the second preset reaction rate comparison parameter, selecting the second reaction rate adjustment coefficient 1.3 to adjust the reaction rate to the corresponding value;

[0089] The adjusted reaction rate is the product of the initial reaction rate and the reaction rate adjustment coefficient.

[0090] Among them, the initial reaction rate is related to the total carbon emissions of the construction building on the day when the reaction carbon fixation mode is started.

[0091] In this embodiment, when the first preset reaction rate comparison parameter and the second preset reaction rate comparison parameter are set, the reaction rate determination parameter is calculated at least 2000 times based on the historical construction data, and a reaction rate determination parameter data set is constructed. The reaction rate determination parameter is used as a random variable, and the random variable obeys the probability density function. Then, a normal distribution curve can be constructed according to the probability density function, and the 95% confidence interval of the normal distribution curve is determined. The reaction rate determination parameter corresponding to the midpoint of the 95% confidence interval is determined as the first preset reaction rate comparison parameter, and the reaction rate determination parameter corresponding to the lower limit of the 95% confidence interval is determined as the second preset reaction rate comparison parameter.

[0092] When the carbon fixation mode is determined to be reactive carbon fixation, the present invention further improves the carbon neutrality efficiency of the construction building by adjusting the reaction rate to adapt to the total carbon emissions of the construction building.

[0093] Specifically, the total carbon emissions of a building on any construction day are the sum of the carbon emissions of the building materials used on that day and the carbon emissions of the construction equipment on that day.

[0094] Specifically, this real-time example is based on a carbon neutrality emission management system for construction, and also includes a display device for displaying carbon emissions and carbon neutrality in real time.
