DETAILED DESCRIPTION OF THE INVENTION
[0008] According to the first embodiment of the present invention, referring to FIG. 1, the analysis method of the hydrogen filling behavior of a fuel cell vehicle based on the big data platform of the present invention includes: extracting a parameter set of the structural design of the hydrogen system of the fuel cell vehicle and a set of driving data A1 of the fuel cell vehicle within a preset time interval from the big data platform of the fuel cell vehicle; extracting a hydrogen filling data set A2 related to the hydrogen filling behavior of the fuel cell vehicle based on the driving data set A1; identifying the occurrence of the hydrogen filling behavior of the fuel cell vehicle according to a preset logical judgment condition based on the hydrogen filling data set A2, and determining the data rows corresponding to before and after hydrogen filling of the fuel cell vehicle; By means of data rows corresponding to before hydrogen filling of the fuel cell vehicle and after hydrogen filling of the fuel cell vehicle, obtaining the attribute change value after the hydrogen filling behavior of the fuel cell vehicle, and calculating the hydrogen filling mass of the fuel cell vehicle, Calculating a first hydrogen filling feature set of the fuel cell vehicle based on all hydrogen filling behavior data in the hydrogen filling data set A2, Based on the hydrogen filling mass and the first hydrogen filling feature set of the fuel cell vehicle, a second hydrogen filling feature set corresponding to when all hydrogen filling behaviors in the hydrogen filling data set A2 occur is obtained, and making hydrogen filling behavior features corresponding to when the fuel cell vehicle travels in a preset time interval, Characterized by including.
[0009] Furthermore, the set of parameters for the hydrogen system structure design of the fuel cell vehicle includes at least the number n_tank of hydrogen storage gas bottles, the nominal water volume V_tank of the hydrogen storage gas bottles, and the nominal operating pressure of the hydrogen storage gas bottles.
[0010] Based on the big data platform of the fuel cell vehicle, obtaining the structure design parameters of the hydrogen system of a certain large truck, among which the number n_tank of hydrogen storage gas bottles is 9, the nominal water volume V_tank of the hydrogen storage gas bottles is 165L, and the nominal operating pressure of the hydrogen storage gas bottles is 35.0 MPa.
[0011] The hydrogen filling data set A2 of the hydrogen filling behavior of the fuel cell vehicle includes at least information transmission time, cumulative driving distance, the highest temperature of the hydrogen system, and the highest hydrogen pressure.
[0012] The first hydrogen filling feature collection of the fuel cell vehicle includes at least the hydrogen storage gas bottle pressure before hydrogen filling of the fuel cell vehicle, the hydrogen storage gas bottle pressure after hydrogen filling of the fuel cell vehicle, the hydrogen storage gas bottle temperature before hydrogen filling of the fuel cell vehicle, and the hydrogen storage gas bottle temperature after hydrogen filling of the fuel cell vehicle.
[0013] The hydrogen filling second feature set includes at least the interval driving distance of hydrogen filling, the interval time of hydrogen filling, the number of hydrogen filling times, the mass of hydrogen filling, and the average hydrogen consumption.
[0014] Furthermore, extracting the hydrogen filling data set A2 regarding the hydrogen filling behavior of the fuel cell vehicle based on the driving data set A1 includes extracting, as the hydrogen filling data set A2, the data regarding the hydrogen filling behavior of the fuel cell vehicle in the n rows of the driving data set A1 sorted in the order before and after the transmission time.
[0015] Based on the big data platform of the fuel cell vehicle, obtain the hydrogen filling data set A2 of a certain large truck in August and sort it into 56162 rows of data according to the order before and after the transmission time.
[0016] The data in the m-th row of the hydrogen filling data set A2 sets the information transmission time as Time_m, the cumulative driving distance as S_m, the highest temperature in the hydrogen system as Temp_m, and the highest hydrogen pressure as P_m. Here, the numerical values of Time_m, S_m, Temp_m, and P_m are all not empty sets and not zero.
[0017] The data in the 2565th row of the hydrogen filling data set A2, the information transmission time is 2022-08-26 01:48:40, the cumulative driving distance is 6269.6 km, the highest temperature in the hydrogen system is 38 °C, and the highest hydrogen pressure is 34.7 MPa.
[0018] The data in the (m - 1)-th row of the hydrogen filling data set A2 sets the information transmission time as Time_m - 1, the cumulative driving distance as S_m - 1, the highest temperature in the hydrogen system as Temp_m - 1, and the highest hydrogen pressure as P_m - 1.
[0019] The data in the 2564th row of the hydrogen filling data set A2, the information transmission time is 2022-08-25 15:50:07, the cumulative driving distance is an empty set, the highest temperature in the hydrogen system is an empty set, and the highest hydrogen pressure is an empty set.
[0020] Furthermore, based on the hydrogen filling data set A2, identifying the occurrence of the hydrogen filling behavior of a fuel cell vehicle according to preset logical judgment conditions and determining the data rows corresponding to before and after the hydrogen filling of the fuel cell vehicle, if the values of Time_m-1, S_m-1, Temp_m-1, and P_m-1 of the data in the (m - 1)-th row of the hydrogen filling data set A2 are all non-empty and non-zero, calculate from the data in the m-th row and the data in the (m - 1)-th row, if the values of Time_m-1, S_m-1, Temp_m-1, and P_m-1 of the data in the (m - 1)-th row of the hydrogen filling data set A2 are empty sets or zero, trace back to the previous valid data row according to the transmission time until a valid data row is found, denote this data row as the (m - a)-th row, where a belongs to the range [1, 2, ··· m - 1], and denote the information transmission time of the (m - a)-th row as Time_m-a, the cumulative driving distance as S_m-a, the maximum temperature in the hydrogen system as Temp_m-a, and the maximum hydrogen pressure as P_m-a, further includes.
[0021] The data in the 2563rd row of the hydrogen filling data set A2, where the information transmission time is 2022-08-25 15:49:57, the cumulative driving distance is 6269.6 km, the maximum temperature in the hydrogen system is 18 °C, and the maximum hydrogen pressure is 13.9 MPa.
[0022] If the data in the m-th row and the data in the (m - a)-th row of the hydrogen filling data set A2 satisfy the following logical judgment conditions, it is considered that the fuel cell vehicle generates a hydrogen filling behavior, otherwise it is considered that the fuel cell vehicle does not generate a hydrogen filling behavior. P_m > P_m-a + B
[0023] Here, B is the pressure change threshold value before and after preset hydrogen filling. The logical judgment condition is that when the pressure change range of the hydrogen storage cylinder of the fuel cell vehicle in adjacent data rows exceeds the pressure change threshold value before and after preset hydrogen filling, the hydrogen filling behavior of the fuel cell vehicle occurs. That is, the hydrogen filling behavior of the fuel cell vehicle causes an increase in the pressure of the hydrogen storage cylinder of the fuel cell vehicle.
[0024] For this large truck, the pressure change threshold value before and after preset hydrogen filling is set to 10 MPa.
[0025] The data in the 2565th row and the 2563rd row of the hydrogen filling data set A2 show that the pressure change value before and after hydrogen filling of the fuel cell vehicle is 20.8 MPa, that is, one hydrogen filling behavior has occurred in the fuel cell vehicle.
[0026] When the hydrogen filling behavior first occurs in the hydrogen filling data set A2, the number of hydrogen fillings is set to 1, and then, each time the hydrogen filling behavior occurs, 1 is added to the number of hydrogen fillings.
[0027] Furthermore, by the data rows corresponding to before hydrogen filling and after hydrogen filling of the fuel cell vehicle, obtaining the attribute change value after the hydrogen filling behavior of the fuel cell vehicle and calculating the hydrogen filling mass of the fuel cell vehicle, The pressure of the hydrogen storage gas cylinder before hydrogen filling of the fuel cell vehicle is denoted as P_before, and P_before = 13.9 MPa, The pressure of the hydrogen storage gas cylinder after hydrogen filling of the fuel cell vehicle is denoted as P_after, and P_after = 34.7 MPa, The temperature of the hydrogen storage gas cylinder before hydrogen filling of the fuel cell vehicle is denoted as Temp_before, and Temp_before = 18 °C, The temperature of the hydrogen storage gas cylinder after hydrogen filling of the fuel cell vehicle is denoted as Temp_after, and Temp_after = 38 °C, Based on the pressure and temperature of the hydrogen storage gas bottle before and after hydrogen filling of the fuel cell vehicle, calculate the hydrogen storage mass m_tank_after after hydrogen filling and the hydrogen storage mass m_tank_before before hydrogen filling of the fuel cell vehicle.

[0028] Furthermore, based on the hydrogen filling mass and the first hydrogen filling feature set of the fuel cell vehicle, it is possible to obtain the second hydrogen filling feature set corresponding to all hydrogen filling behaviors occurring within the hydrogen filling data set A2, where the interval driving distance during hydrogen filling is equal to the difference in the cumulative driving distance of the fuel cell vehicle corresponding to when two adjacent hydrogen filling behaviors occur,

[0029] When the above values are substituted and calculated, the average hydrogen consumption is 0.14 kg / km, that is, the average hydrogen consumption per 100 km is 14 kg / 100 km.
[0030] Furthermore, the present invention can create hydrogen filling behavior characteristics corresponding to when the fuel cell vehicle travels in a preset time interval.
[0031] In this embodiment, the interval driving distance distribution of hydrogen filling, the interval time distribution of hydrogen filling, the scatter distribution of interval driving distance - interval time of hydrogen filling, the mass distribution of hydrogen filling, and the distribution of average hydrogen consumption can be created, and the hydrogen filling characteristics corresponding to when the vehicle is traveling within the preset time interval can be obtained, providing a reference for the hydrogen filling rule analysis of the fuel cell vehicle, the geographical location of the urban integrated hydrogen station, the planning and layout of hydrogen filling capacity.
[0032] Referring to FIG. 2, the hydrogen filling behavior characteristics include at least the interval driving distance distribution of the vehicle's hydrogen filling. As can be seen from the figure, the interval driving distance of hydrogen filling and its ratio show a normal distribution as a whole. As the interval driving distance of hydrogen filling increases, the ratio gradually increases, and then, as the interval driving distance of hydrogen filling further increases, the ratio gradually decreases.
[0033] Referring to Fig. 3, the characteristics of the hydrogen filling behavior further include at least the interval time distribution of vehicle hydrogen filling. It can be seen that the ratios of the interval driving distances of hydrogen filling within 24 hours, 24 to 48 hours, and less than 48 to 72 hours are 28.4%, 45%, and 13.5% respectively, with a total of approximately 86.9%. In particular, the interval time during which 3.7% of the hydrogen filling behaviors occur exceeds 120h. This indicates that some vehicles may not be in a driving state on a certain day, or some vehicles may highly depend on the power battery system during driving, resulting in a longer interval time for hydrogen filling.
[0034] Referring to Fig. 4, the characteristics of the hydrogen filling behavior further include at least the interval distance-interval time distribution status of vehicle hydrogen filling. In the figure, the interval distances of hydrogen filling are mainly distributed within the range of 50km to 300km, the interval times of hydrogen filling mainly concentrate within the range of 0 to 96h, and the interval distances of hydrogen filling for extremely few vehicles with hydrogen filling behaviors are greater than 350km, or the interval times of hydrogen filling are greater than 192h.
[0035] Referring to Fig. 5, the characteristics of the hydrogen filling behavior include at least the probability distribution status of the interval driving distance-interval time of vehicle hydrogen filling. In the figure, the range where the hydrogen filling behavior is most intensive is that the interval driving distance of hydrogen filling is 150km to 200km and the interval time of hydrogen filling is 24h to 48h, and the occupied ratio reaches 18%. Next, the interval driving distance of hydrogen filling is 200km to 250km and the interval time of hydrogen filling is 24h to 48h, and the occupied ratio reaches 14%. Considering that the pure hydrogen driving distance of the vehicle is 340km, the area where the hydrogen filling behavior in the vehicle column is most intensive is that the interval driving distance of hydrogen filling is about 50% of the pure hydrogen driving distance, which has a certain relationship with the construction of local hydrogen stations and the layout of geographical locations.
[0036] Referring to Fig. 6, the characteristics of the hydrogen filling behavior include at least the pressure distribution of the hydrogen gas tank before and after hydrogen filling of the vehicle. As shown in the figure, the pressure distribution of the hydrogen gas tank before hydrogen filling is relatively wide, with a certain distribution between 3 MPa and 20 MPa. After hydrogen filling, the pressure of the hydrogen gas tank mainly concentrates between 25 MPa and 35 MPa, and there is a small scattered distribution in the remaining area. The pressure after hydrogen filling is most concentrated near 35 MPa, and the hydrogen filling behavior in this part is in a full-hydrogen state. There is also a certain distribution near 30 MPa.
[0037] Referring to Fig. 7, the characteristics of the hydrogen filling behavior further include at least the mass distribution of a single hydrogen filling of the vehicle. As can be seen from the figure, as the mass of a single hydrogen filling increases, the ratio shows a tendency of "first increasing and then decreasing". The mass of a single hydrogen filling mainly concentrates on 18 kg - 21 kg, 21 kg - 24 kg, and 24 kg - 27 kg, and the ratios are 21.6%, 27.2%, and 20.4% respectively. The ratio of the mass of a single hydrogen filling being less than 12 kg is only 4.4%.
[0038] Referring to Fig. 8, the characteristics of the hydrogen filling behavior also include at least the situation of the average hydrogen consumption distribution per 100 kilometers of the vehicle. As can be seen from the figure, the proportion of the average hydrogen consumption distribution in the range of 10 kg / 100 km - 12 kg / 100 km is the highest, reaching 35.1%, followed by the interval of 12 kg / 100 km - 14 kg / 100 km. When comprehensively comparing the hydrogen consumption of different vehicles, the hydrogen consumption is related to the differences in vehicle types, the load of transportation operations, environmental temperatures, and the differences in respective technologies.
[0039] According to the second embodiment of the present invention, referring to Fig. 9, the present invention claims the protection of an analysis system for the hydrogen filling behavior of a fuel cell vehicle based on a big data platform. A memory for non-temporarily storing computer-readable instructions, A processor for historically recording the computer-readable instructions so as to implement an analysis method for the hydrogen filling behavior of a fuel cell vehicle based on a big data platform when executed.
