Description

Technical Field

[0001] The present invention relates to the technical field of intelligent scheduling, and in particular to an intelligent scheduling system for hydrogen filling of hydrogen fuel cell vehicles. Background Art

[0002] Hydrogen fuel refers to liquid hydrogen fuel, which is a colorless gas. Burning one gram of hydrogen can release 142 kilojoules of heat. Its combustion product is water, without ash and exhaust gas, and will not pollute the environment. Hydrogen is extremely light in weight, so it is inconvenient to carry and transport. However, hydrogen as a fuel is still considered to be the most ideal energy source in the 21st century. The outstanding characteristics of hydrogen fuel as an energy source are pollution-free, high efficiency and recyclability. Hydrogen burns most cleanly. Except for water and a small amount of hydrogen nitride, it does not produce pollutants such as carbon monoxide, carbon dioxide, hydrocarbons, lead compounds, dust particles and other pollutants that are harmful to the environment. A small amount of hydrogen nitride will not pollute the environment after proper treatment, and the water generated by combustion can continue to produce hydrogen and be recycled repeatedly.

[0003] When the common hydrogen refueling intelligent scheduling system is in use, it cannot timely grasp which hydrogen refueling guns are overused or underused, so it is difficult to balance the frequency of use of each hydrogen refueling gun, which can easily cause some hydrogen refueling guns to be damaged prematurely due to excessive use. At the same time, it can also easily lead to an increase in the frequency of maintenance of hydrogen refueling stations, making users feel insecure. For this reason, we propose a hydrogen fuel cell vehicle hydrogen refueling intelligent scheduling system. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent scheduling system for hydrogen filling of hydrogen fuel cell vehicles.

[0005] In order to solve the problems raised in the above background technology, the present invention provides the following technical solutions: a hydrogen fuel cell vehicle hydrogen refueling intelligent scheduling system, comprising an information collection module, the information collection module is used to collect hydrogen refueling vehicle information and hydrogen refueling station information, and also includes a standard capacity module, a waiting time prediction module, a station addition module, a frequency analysis module and a broadcast control module; The standard capacity module extracts the model information of different hydrogen refueling vehicles and the hydrogen refueling capacity information of different hydrogen refueling vehicles, establishes the same capacity model folder according to the hydrogen refueling capacity of different hydrogen refueling vehicles, and then records the information of hydrogen refueling vehicles with the same hydrogen refueling capacity into the same capacity model folder; The waiting time prediction module collects the license plate information of hydrogen refueling vehicles in advance, obtains the model information of hydrogen refueling vehicles, analyzes the normal hydrogen refueling capacity of hydrogen refueling vehicles, and establishes a vehicle terminal at the same time. The vehicle terminal is used to obtain the hydrogen refueling demand of hydrogen refueling vehicles in advance, and then the waiting time required for different hydrogen refueling vehicles is calculated based on the hydrogen refueling demand information, the time required to enter the hydrogen refueling location, and the time to leave the location, and the predicted waiting time information is obtained; A new module is added to the station to establish a waiting threshold, determine the relationship between the predicted waiting time information and the waiting threshold, and control the status of the hydrogen refueling station based on the relationship between the predicted waiting time and the waiting threshold; The frequency analysis module formulates the standard number of hydrogenation for different hydrogenation guns, and simultaneously collects the number of times the hydrogenation guns are used, and then formulates the update cycle unit, wherein the update cycle unit includes the update cycle, and then uses the decreasing formula to reduce the standard number of hydrogenation, obtain the remaining number of hydrogenation information, calculate the difference in the remaining number of hydrogenation information between different hydrogenation guns, and re-update the standard number of hydrogenation when entering the next update cycle. At this time, the difference in the remaining number of hydrogenation information between different hydrogenation guns is added to the standard number of hydrogenation to generate the total number of hydrogenation; The broadcast control module provides voice guidance and control for hydrogen refueling vehicles based on the total number of hydrogen refueling times of different hydrogen refueling guns, so that designated hydrogen refueling vehicles use designated hydrogen refueling guns for hydrogenation, thereby alleviating the problem of large differences in information on the remaining number of hydrogen refueling times between different hydrogen refueling guns.

[0006] As a further solution of the present invention: when establishing the same capacity model folder, the standard capacity module will simultaneously establish an expanded capacity unit, use the expanded capacity unit to collect information on hydrogenation vehicles with expanded hydrogenation capacity function, analyze the expansion standard of hydrogenation capacity, calculate the actual hydrogenation capacity information of hydrogenation vehicles after executing different expansion standards, and record it in the expanded capacity unit to generate a vehicle expansion table.

The method for the hydrogen refueling station to obtain the hydrogen refueling demand of the hydrogen refueling vehicle is as follows: The first method is that the user inputs the hydrogen refueling demand information into the vehicle end. When the vehicle end receives the access signal of the hydrogen refueling station, the information about the hydrogen refueling capacity and the hydrogen refueling demand information in the vehicle end is fed back to the hydrogen refueling station. The second method is that the user directly tells the staff at the hydrogen filling station about his hydrogen filling needs.

[0008] As a further solution of the present invention: when the waiting time prediction module receives the hydrogenation capacity information and the hydrogenation demand information, the number of queues is set as P, and the time required to enter the hydrogenation position is set as , assuming the hydrogenation demand is , assuming the hydrogenation rate is , assuming the departure time is , let the predicted waiting time be ; ; The predicted waiting time is calculated according to the above formula. When the vehicle does not feedback the hydrogen refueling demand information, the hydrogen refueling demand will be directly calculated according to the hydrogen refueling capacity.

[0009] As a further solution of the present invention: after the site adding module establishes the waiting threshold, the waiting threshold is set to ; when There is no need to temporarily open other hydrogen refueling stations when the when When the demand for hydrogen is high, other hydrogen refueling stations need to be opened temporarily.

[0010] As a further solution of the present invention: when the station-added module completes the control of the status of the hydrogen refueling station, it will establish an early warning index, and the early warning index is set to ; when When the emergency occurs, the staff at the hydrogen refueling station will be reminded so that they can go to other hydrogen refueling stations that are temporarily opened in time.

[0011] As a further solution of the present invention: when the frequency analysis module calculates the difference between the remaining hydrogenation times of different hydrogenation guns, it will sort the remaining hydrogenation times, and then extract the last remaining hydrogenation times information and use it as the standard base number. Let the standard base number be , assuming that the remaining number of hydrogenation times of the remaining hydrogenation guns is , , ,……, , assuming that the difference in the remaining number of hydrogenation times for different hydrogenation guns is , , ,……, ; ; The difference in the remaining number of hydrogenation times of different hydrogenation guns is calculated according to the above formula.

[0012] As a further solution of the present invention: after calculating the difference in the number of remaining hydrogenation times of different hydrogenation guns, the frequency analysis module extracts the first remaining number of hydrogenation times and the last remaining number of hydrogenation times, and sets the standard number of hydrogenation times as , let the last remaining number of hydrogenation be , let the remaining number of the first hydrogenation be , assuming the height difference ratio is ; ; The height difference ratio is calculated according to the above formula.

[0013] As a further solution of the present invention: after calculating the high-low difference ratio, the frequency analysis module establishes a ratio threshold, and the ratio threshold is set to ,when When the hydrogenation priority of the hydrogenation gun corresponding to the last remaining number of hydrogenation times is adjusted to be lower than the hydrogenation priorities of other hydrogenation guns, the hydrogenation priority of the hydrogenation gun corresponding to the first remaining number of hydrogenation times is set to be higher than the hydrogenation priorities of other hydrogenation guns.

[0014] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are: 1.

At this time, the difference in the remaining number of hydrogenation times between different hydrogenation guns will be added to the standard number of hydrogenation. According to the total number of hydrogenation times of different hydrogenation guns, the hydrogenation vehicles are voice-guided and controlled, so that the designated hydrogenation vehicles use the designated hydrogenation guns for hydrogenation. Furthermore, the waiting time prediction module can help users know the approximate waiting time in advance and arrange their trip reasonably, thus avoiding the time wasted by blind waiting. It also reduces the driver's anxiety that may be caused by long waiting time and improves the overall operational efficiency of the hydrogen refueling station.
