Description

Technical Field

[0001] The present invention relates to the technical field of electronic digital data processing, and in particular to a carbon emission calculation method and system for the collection, transportation and treatment of construction waste. Background Art

[0002] my country has a huge stock of construction waste, which is not only difficult to transport and pollutes the environment, but also occupies land area, and even pollutes water resources and air, thus affecting people's normal production and life. Most construction waste is solid waste. The existing technology mainly uses landfill, incineration, recycling and reuse methods to treat solid construction waste. The most common method is landfill, which collects and transports solid construction waste to landfills; and the method with the highest carbon emissions is incineration, which will generate a large amount of carbon emissions during the incineration process. In the process of landfill treatment of construction waste, its collection and transportation will generate additional carbon emissions, such as the consumption of electricity and fuel energy; and the specific treatment methods of construction waste, such as landfill, incineration, recycling, etc., will also generate certain carbon emissions.

[0003] The traditional method of calculating carbon emissions from the collection, transportation and treatment of construction waste is to monitor carbon emissions in landfills or during incineration, but ignores some additional carbon emissions that occur during the transportation of construction waste. For example, during the transportation of construction waste, vehicles will emit carbon dioxide, and the pollution of the surrounding air by construction waste and the subsequent cleaning process will produce invisible carbon emissions, resulting in inaccurate calculation of carbon emissions during the collection, transportation and treatment of construction waste.

Obviously, the drawings described below are only some embodiments of the present invention.

[0042] Figure 2 Flowchart for obtaining carbon emissions from construction waste collection, transportation and treatment. DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] An embodiment of a carbon emission calculation method for the collection, transportation and treatment of construction waste according to the present invention is as follows: Figure 1 As shown, including:

[0045] S1. Collect the carbon emissions at each monitoring point in each time period and the carbon emission factors and vehicle speeds of vehicles passing through the monitoring points.

[0046] At present, in order to achieve the carbon emission goals of "carbon peak" and "carbon neutrality", regulatory authorities usually set up carbon emission gas detectors in cities to obtain carbon emission monitoring data of construction waste transport vehicles on their routes; at the same time, the speed of transport vehicles also has an economic speed, that is, the closer the speed is to the economic speed, the lower the vehicle's carbon emissions.

[0047] Based on this, this embodiment sets a monitoring point at each carbon emission gas detector on the route of construction waste transport vehicles, counts the number of monitoring points Z, places vehicle speed meters at the monitoring points to monitor vehicle speed, installs cameras at the monitoring points, obtains the type of vehicle by photographing the vehicle's license plate information, and then obtains the vehicle's carbon emission factor, where each type of vehicle corresponds to a carbon emission factor. The number of vehicles n passing through the monitoring point and the speed of the vehicle when passing through the monitoring point are obtained within a time period T. The empirical value of T is 10 minutes, where the speed of the mth vehicle passing through the ith monitoring point in the ath time period is The carbon emission factor of the mth vehicle passing through the ith monitoring point in the ath time period is At the middle of each time period, the carbon emission is collected once by the carbon emission gas detector to obtain the carbon emission of the i-th monitoring point in the a-th time period.

[0048] At this point, the carbon emissions at each monitoring point within the time period, the speed of vehicles passing through each monitoring point, and the carbon emission factor are obtained.

[0049] S2. Obtain the carbon emission impact factor based on the carbon emission factor and vehicle speed of the vehicles passing through the monitoring point; obtain the overall impact coefficient of the construction waste transport vehicle based on the carbon emission factor of the construction waste transport vehicle compared with the carbon emission impact factor of all vehicles passing through the monitoring point, and then obtain the carbon emissions of the construction waste transport vehicle in combination with the carbon emissions at the monitoring point within the time period.

[0050] Since construction waste transport vehicles are larger than ordinary vehicles, their engines generate larger carbon emissions during operation. At the same time, construction waste releases carbon dioxide during decomposition and accumulation, which increases the carbon emissions at each monitoring point when the construction waste transport vehicles pass through the monitoring points. This embodiment solves the problem that the calculation of carbon emissions from the collection, transportation and treatment of construction waste ignores the additional carbon emissions generated by vehicles and construction waste during transportation. By analyzing the factors affecting the calculation of carbon emissions from construction waste transport vehicles on the transportation route, the total carbon emissions of construction waste transport vehicles on the transportation route are obtained, and then the carbon emissions from the collection, transportation and treatment of construction waste are obtained, such as Figure 2 The figure shows a flow chart for obtaining carbon emissions from the collection, transportation and treatment of construction waste.

[0051] When a construction waste transport vehicle passes through a monitoring point in the ath time period, all vehicles passing through the time period will have a certain impact on the carbon emissions at the monitoring point. The more vehicles passing through, the greater the impact on the carbon emissions monitoring results. Therefore, according to the different types and speeds of vehicles passing through the monitoring point, the impact of vehicles passing through the monitoring point in the time period on the carbon emissions monitoring results at the monitoring point is obtained, where the carbon emission impact factor at the i-th monitoring point in the ath time period is The calculation formula is:

[0052]

[0053] In the formula, is the carbon emission impact factor at the i-th monitoring point in the a-th time period, is the number of vehicles passing through the i-th monitoring point in the a-th time period, is the speed of the mth vehicle passing the ith monitoring point in the ath time period, K is the vehicle carbon emission impact factor of the mth vehicle at the ith monitoring point in the ath time period, is the carbon emission factor of the mth vehicle passing through the ith monitoring point in the ath time period.

[0054] It should be noted that the carbon emission factors of various types of vehicles are fixed values, and different types of vehicles have different engine models and different carbon emission levels. Therefore, when the vehicle's driving speed is too high or the vehicle's engine carbon emission factor is large, the carbon emission impact factor of the vehicle passing at that moment will be greater, which will result in a larger carbon emission amount monitored during that time period.

[0055] Based on the above analysis, construction waste transport vehicles have additional carbon emissions from construction waste compared to ordinary vehicles, thereby increasing the carbon emissions at the monitoring point. Therefore, the construction waste transport vehicles passing through the monitoring point are calculated separately to obtain the overall impact coefficient of the construction waste transport vehicles at the monitoring point compared to all vehicles passing through the monitoring point. The calculation formula is:

[0056]

[0057] In the formula, is the overall impact coefficient of the construction waste transport vehicle JZ at the i-th monitoring point, is the vehicle carbon emission impact factor of the construction waste transport vehicle JZ at the i-th monitoring point in the a-th time period, S is the number of time periods, and the empirical value is 200. is the carbon emission influencing factor at the i-th monitoring point in the a-th time period.

[0058] When the vehicle carbon emission impact factor of the construction waste transport vehicle at the monitoring point accounts for a larger proportion of the carbon emission impact factor at the monitoring point, it means that the construction waste transport vehicle at the monitoring point contributes more to the carbon emissions. The greater the overall impact coefficient of the construction waste transport vehicle at the monitoring point, the greater the impact on the carbon emissions detection results.

[0059] Since construction waste transport vehicles will generate greater gas pollution wherever they pass, this embodiment uses the above analysis to obtain the impact of construction waste transport vehicles on carbon emissions, and calculates the carbon emissions of construction waste transport vehicles at the i-th monitoring point in the a-th time period. Expressed as the carbon emissions of the ith monitoring point in the ath time period The overall impact coefficient of the construction waste transport vehicle JZ at the i-th monitoring point The product of .

[0060] At this point, the carbon emissions of construction waste transport vehicles at each monitoring point within the time period are obtained.

[0061] S3. By analyzing the correlation between the speed and carbon emissions of construction waste transport vehicles, the trend isotropic difference coefficient is constructed to evaluate the correlation between the speed and carbon emissions, and then the trend delay deviation is obtained to evaluate the accuracy of the calculation of carbon emissions of construction waste transport vehicles; different weights are set for the carbon emissions of construction waste transport vehicles at the monitoring point according to the trend delay deviation, and the total carbon emissions of construction waste transport vehicles on the transportation route are calculated.

[0062] It should be noted that the different speeds of construction waste transport vehicles in different time periods often affect the changing trend of carbon emissions from construction waste transport vehicles. The change in speed is correlated with the change in carbon emissions. An increase in speed means that more fuel needs to be burned, thereby increasing carbon emissions. The carbon emission data of general construction waste transport vehicles should show a relatively similar trend of change with the change in vehicle speed. That is to say, the fluctuation trend of carbon emissions from construction waste transport vehicles in continuous time periods mainly depends on the correlation with the vehicle's running speed. In order to evaluate the similar changing trends in the speed and carbon emissions data of construction waste transport vehicles, the trend isotropic difference coefficient is calculated. First, the speeds of construction waste transport vehicles passing the i-th monitoring point in all time periods are arranged in chronological order to obtain the speed sequence V of the construction waste transport vehicles at the i-th monitoring point. i ; Arrange the carbon emissions of construction waste transport vehicles passing through the i-th monitoring point in all time periods in chronological order, and obtain the carbon emissions sequence T of the construction waste transport vehicles at the i-th monitoring point i The calculation formula of the trend isotropic difference coefficient is:

[0063]

[0064] Among them, D i is the trend isotropic difference coefficient at the i-th monitoring point, S is the number of time periods, is the speed of the construction waste transport vehicle passing the i-th monitoring point in the k-th time period, is the carbon emission of the construction waste transport vehicle passing through the i-th monitoring point in the k-th time period, is the trend difference when the construction waste transport vehicle passes the i-th monitoring point in the k-th time period, is the trend difference of the construction waste transport vehicle passing through the i-th monitoring point in the k+1th time period, dtw(V i ,T i ) is the speed sequence V of the construction waste transport vehicle at the i-th monitoring point i With carbon emission series T i The distance between them, this embodiment uses the dtw dynamic time warping distance.

[0065] The smaller the DTW distance between the speed series and the carbon emission series of construction waste transport vehicles, the more synchronized the changing trends of the two series are, and the smaller the trend isotropic difference coefficient is; the greater the difference between the speed and carbon emissions in two adjacent time periods, the greater the difference between the changes in the speed series and the carbon emission series, the greater the trend isotropic difference coefficient is, and the lower the credibility of the carbon emissions of construction waste transport vehicles.

[0066] At the same time, there will be a delay in the correlation between the speed sequence and the carbon emission sequence of construction waste transport vehicles at each monitoring point. For example, carbon emissions can only show an increasing trend after the speed increases for a period of time. Therefore, it is also necessary to evaluate the influence relationship between the speed sequence and the carbon emission sequence by calculating the degree of deviation. The trend delay deviation at the monitoring point is calculated as follows:

[0067] E i =D i *SBD(V i ,T i )

[0068] In the formula, E i is the trend delay deviation at the i-th monitoring point, D i is the trend isotropic difference coefficient of the ith monitoring point, SBD(V i ,T i ) is the speed sequence V of the construction waste transport vehicle at the i-th monitoring point i With carbon emission series T i The SBD between them is based on the morphological distance.

[0069] It should be noted that the SBD distance measures the similarity between two sequences. The SBD distance indicates the distance the sequences move when the two sequences reach the most similar state. Therefore, the larger the SBD distance between the vehicle speed sequence and the carbon emission sequence, the greater the delay in carbon emissions as the speed changes, and the greater the trend delay deviation. When the trend isotropic difference coefficient is smaller, it means that the difference in the changing trends of the two sequences is smaller, the possibility of delay in the carbon emission sequence is smaller, and the trend delay deviation is smaller, and the error of the calculated carbon emission data of construction waste transportation vehicles is smaller.

[0070] The trend delay deviation at the monitoring point reflects the credibility of the carbon emission data of the construction waste transport vehicles. Therefore, this embodiment sets different weights for the carbon emission data of the construction waste transport vehicles at the monitoring point according to the trend delay deviation at each monitoring point, and calculates the total carbon emission YS of the construction waste transport vehicles on the transport route. The calculation formula is:

[0071] P i =exp(-E i )

[0072]

[0073] Among them, YS is the total carbon emissions of construction waste transport vehicles on the transport route, E i The trend delay deviation at the i-th monitoring point, exp() is an exponential function with a natural constant as the base, P i is the carbon emission weight at the i-th monitoring point, S is the number of time periods, is the carbon emission of the construction waste transport vehicle passing through the ith monitoring point in the kth time period, and Z is the number of monitoring points.

[0074] At this point, the total carbon emissions of construction waste transport vehicles on the transport route are obtained.

[0075] S4. Count the carbon emissions from the collection and treatment of construction waste, and combine the total carbon emissions from construction waste transport vehicles on the transportation route to obtain the carbon emissions from the collection, transportation and treatment of construction waste.

[0076] The carbon emissions during the collection of construction waste are estimated by the type and composition of construction waste in the construction project, and the carbon emissions during the collection of construction waste are obtained.

[0077] According to the final treatment method of construction waste, the carbon emissions of construction waste during the treatment process are obtained through sensor technology. The carbon emissions of construction waste collection, transportation and treatment are expressed as the sum of the carbon emissions during the collection process of construction waste, the carbon emissions during the treatment process of construction waste and the total carbon emissions of construction waste transportation vehicles on the transportation route.

[0078] At this point, the carbon emissions from the collection, transportation and treatment of construction waste have been obtained.

[0079] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a carbon emission calculation system for the collection, transportation and treatment of construction waste, including a memory, a processor and a computer program stored in the memory and running on the processor. When the processor executes the computer program, the steps of any one of the above-mentioned carbon emission calculation methods for the collection, transportation and treatment of construction waste are implemented.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the protection scope of the present invention.
