The cargo information includes cargo name, cargo weight and cargo code. Specifically, the cargo identification module also includes configuration equipment such as gain antenna, router, power supply, etc. The RFID reader needs to be powered on and connected to a 4G router. The number of gain antennas depends on the size of the transport vehicle. They are distributed and fixedly installed inside the transport vehicle compartment and connected to the RFID reader.

[0052] Before a transport vehicle carries out a task of transporting a batch of goods, it needs to enter the basic information of the batch of goods into the cargo transportation carbon emission accounting system in advance, including the name of the goods, the weight of the goods G-name and the epc number (i.e. the cargo code) of the bound tag. The epc number of the tag needs to be read and entered using an RFID reader. After the basic information of the goods is entered, the RFID tag needs to be affixed to the corresponding bound goods for scanning and identifying the goods during transportation.

[0053] In the carbon emission accounting module, the accounting model of total carbon emissions is included. The carbon emissions generated during the transportation of goods include direct carbon emissions from gasoline combustion and indirect carbon emissions from gasoline production. Therefore, the model algorithm is as follows:

[0054] E 总 =E 直接 +E 间接

[0055] Among them, E 总 is the total carbon emissions generated by freight transportation, E 直接 Direct carbon emissions from freight transportation, E 间接 Indirect carbon emissions from the transportation of goods.

[0056] The greenhouse gases produced by gasoline during combustion include not only carbon dioxide, but also methane and nitrous oxide. Therefore:

[0058] Among them, E 二氧化碳 is the carbon dioxide emissions from gasoline combustion, E 甲烷 is the methane emission equivalent produced by gasoline combustion, E 氧化亚氮 It is the equivalent of nitrous oxide emissions produced by gasoline combustion.

[0070] The algorithm for obtaining the carbon emissions generated by each cargo transportation is as follows:

[0071] E name =E 单位 ×G name

[0072] Among them, E name The carbon emissions generated by the corresponding goods in this cargo transportation, G name The weight of the goods with the corresponding name.

[0073] Embodiment 2

[0074] Based on the above-mentioned embodiment of the cargo transportation carbon emission accounting system, the embodiment of the present invention provides a cargo transportation carbon emission accounting method, comprising the following steps:

[0075] S1: Before executing a transportation task that requires calculating carbon emissions of goods, maintain the values ​​and units corresponding to the basic parameters of the accounting model in the system, and enter the basic information of the vehicle, including the license plate number and the reader number installed on the vehicle;

[0076] S2: After the goods with RFID tags are moved to the transport vehicle, the vehicle starts at location a, the RFID reader is powered on, and the gain antenna begins to scan and read the tag epc number of the goods on the vehicle, and transmits it to the accounting system through the 4G router and stores it in the database. The fuel collection module collects the remaining fuel M of the transport vehicle after power is turned on. a , the positioning module reports the vehicle’s current driving trajectory K in real time a To the accounting system, stored in the database;

[0077] S3: When the transport vehicle stops at location b and starts again, the RFID reader will scan the tag on the transport vehicle again and upload the scanned tag epc number to the accounting system and store it in the database. At the same time, the comparison module will compare it with the tag epc number obtained last time to determine whether the goods are loaded or unloaded. If so, carbon emissions need to be calculated, triggering the carbon emissions accounting module to calculate carbon emissions. At the same time, the fuel collection module collects the remaining fuel M of the transport vehicle. b , the positioning module reports the vehicle’s current driving trajectory K in real time b To the accounting system and stored in the database.

[0078] Specifically, the judgment results of the comparison module are divided into the following situations:

[0079] ① The epc number of the comparison tag has not changed, which means that the transport vehicle did not load or unload goods after it stopped driving;

[0080] ② Compare the labels with only multiple epc numbers, which means that the transport vehicle was loaded with goods after it stopped driving;

[0081] ③ Compare the labels with only a few EPC numbers, which means that the transport vehicle stopped driving and unloaded the goods;

[0082] ④ Comparing the epc numbers of the tags that have both more and less, it means that after the transport vehicle stopped driving, the goods were loaded and unloaded at the same time.

[0083] S4: The carbon emission calculation module calculates the total carbon emissions between the transport points based on the fuel consumption and mileage, and calculates the carbon emissions per unit mass of the goods based on the cargo information. The total carbon emissions E from point a to point b are obtained according to the algorithm formula in Example 1. a-b for:

[0084] E a-b =M a-b ×NCV×CC×OF×44 / 12+K a-b ×EF 甲烷 ×GWP 甲烷 +K a-b ×EF 氧化亚氮 ×GWP 氧化亚 +M×L

[0085] Thus, the carbon emissions per unit mass generated by the transport vehicle from point a to point b are obtained: (a-b)单位 for:

[0086] E (a-b)单位 =E a-b / G all

[0087] The carbon emissions generated by each cargo transportation (a-b)name for:

[0088] E (a-b)name =E (a-b)单位 ×G name

[0089] In step S3, situation ① indicates that the transport point has not yet been reached, so there is no need to calculate the carbon emissions of the goods. It is only necessary to record the fuel consumption, mileage and other information corresponding to the current transport point, and summarize the fuel consumption and mileage information after arriving at the transport point, and then calculate the carbon emissions; situation ② indicates that the transport point of the goods has not yet been reached. At this time, the fuel consumption, mileage and other information corresponding to the current transport point are recorded, and the carbon emissions from a to b are calculated first. In some other embodiments, the relevant information can also be recorded and the carbon emissions are calculated after the transport of the goods is completed; situations ③④ indicate that some goods have arrived at the transport point, so the carbon emissions of the goods need to be calculated.

[0090] When the goods arrive at b, they are not unloaded and need to be transported to the next transportation point, e. Therefore, after arriving at e from b, the unit mass emission E from b to e is calculated based on the above formula. (b-e)单位 , thereby calculating the total carbon emissions of each cargo.

[0091] Based on this embodiment, cargo accounting is performed each time the transport vehicle is started, and carbon emissions are calculated when the cargo changes. The calculation process is more automated and intelligent, and can adapt to a variety of transportation situations. At the same time, the method of only calculating carbon emissions when the cargo changes reduces a certain amount of computing power.

[0092] Embodiment 3

[0093] After arriving at the transportation location, it is not necessary to unload all the goods, but only unload part of the goods, and then go to the next transportation location to transport the remaining goods. Therefore, there is a need to quickly calculate the carbon emissions of the unloaded goods. In this embodiment, according to the first embodiment, it can be obtained:

[0094] E 卸载 =E 单位 ×G 卸载

[0095] Among them, E 卸载 The carbon emissions generated during the transportation of all the goods unloaded this time, G 卸载 It is the sum of the weights of all cargo unloaded.

[0096] Embodiment 4

[0097] In the actual cargo transportation process, there is often a situation where the fuel is insufficient and needs to be refueled. If the transport vehicle travels from place A to place B and refuels at place C, the total carbon emissions generated by the transport vehicle transporting the entire vehicle from place A to place B are E a-b The fuel consumption M in the calculation algorithm a-b The calculation needs to be adjusted to:

[0098] M a-b =(M a -M c1 )+(M c2 -M b )

[0099] Among them, M c1 M is the final remaining oil volume collected before the transport vehicle drives to c for refueling. c2 The initial remaining fuel volume of the transport vehicle after refueling at location c.

[0100] In the current invention, the fuel quantity collection module needs to monitor the remaining fuel quantity of the transport vehicle in real time to determine the time for refueling the transport vehicle, so as to accurately calculate the fuel consumption of the transport vehicle during driving. During the driving process of the transport vehicle, the fuel quantity should be gradually reduced. If the system detects that the fuel quantity suddenly increases a lot at a certain moment, the moment will be marked as the refueling time.

[0101] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
