本发明涉及空中交通流量管理领域，特别涉及一种可应用于空中交通流量管理、并可有效地解决空中交通拥挤问题的航班过台间隔的实现方法。The invention relates to the field of air traffic flow management, in particular to a method for realizing flight transition intervals which can be applied to air traffic flow management and can effectively solve the problem of air traffic congestion.
背景技术Background technique
作为空中交通流量管理系统的理论核心，系统运行管理算法是分析空中交通形势，评估预测空中交通系统容量，提出科学、合理、可行的流量管理建议解决空中交通拥挤问题的理论核心。As the theoretical core of the air traffic flow management system, the system operation management algorithm is the theoretical core of analyzing the air traffic situation, evaluating and predicting the capacity of the air traffic system, and proposing scientific, reasonable and feasible flow management suggestions to solve the problem of air traffic congestion.

考虑来自空域中、各机场的多种限制，为未起飞的航班分配起飞时间是实施预战术、战术空中交通流量管理的一项主要任务。航班的起飞时间分配，即从一个或者多个机场起飞的航班，考虑到起降机场、沿途航线的各项容量限制，为航班生成一个合理的起飞时间。Allocating departure times for non-flighted flights is a major task in the implementation of pre-tactical and tactical air traffic flow management, taking into account the various constraints from each airport in the airspace.

Although the traffic management program also generates the intended departure time for flights outside the control area, it is impossible to control the intended departure time because it is not in the control area. In air traffic flow management, there is still a lack of a method for realizing flight transition intervals that can effectively solve the problem of air traffic congestion.

(2) (2)

FINTD＝FINTA-FETE (6)FINTD = FINTA - FETE (6)
M＝n\m (7)M＝n\m
其中：FSCH——航班的班期到达时间，FIGT——航班的班期挡轮挡时间，TAXI——滑行时间，D——目的空域代码，FARR—航班的目的空域，A——控制起始时间，B——控制终止时间，FETA——航班的预计到达时间，F——受影响航班集合，FActive——活动中的航班；C——程序发布时间，H——豁免起飞时间，FInF1——飞行中的航班，F3——优先机场起飞的航班，FDepAirport——航班的起飞机场，EmptDepApt——优先机场，F1——优先航班，F2——输入的优先航班，Finternational——国际航班，FINTD——意图起飞时间，FINTA——意图到达时间，FETE——预计飞行时间。M——某时段的过台间隔时间值，n——某时段的分钟数，m——意图过台时间处于某时段的航班数量。Among them: FSCH ——schedule arrival time of flight, FIGT ——block time of flight schedule, TAXI——taxi time, D——destination airspace code, FARR ——flight destination airspace, A——control start start time, B—control end time, FETA —flight estimated time of arrival, F—affected flight collection, FActive —flight in action; C—program release time, H—exempt departure time , FInF1 - flight in flight, F3 - flight from priority airport, FDepAirport - departure airport of flight, EmptDepApt - priority airport, F1 - priority flight, F2 - input priority Flight, Finternational - international flight, FINTD - intended departure time, FINTA - intended arrival time, FETE - estimated flight time. M——the value of the crossing interval in a certain period, n——the number of minutes in a certain period, m——the number of flights whose intended crossing time is in a certain period.
读入完整的控制参数。从流量管理程序生成/评估子系统中获取目的空域名称、目的空域代码D、控制起始时间A、控制终止时间B、豁免起飞时间H、影响机场InFluenceDepApt、优先机场EmptDepApt、优先航班F2、实施统一进区域间隔起飞机场MITApt、实施统一进区域间隔起飞机场分组MITAptGroup等参数。Read in complete control parameters.

筛选受影响航班，按式(2)筛选受影响航班。To filter the affected flights, filter the affected flights according to formula (2).
筛选优先航班，从飞行计划或4D航迹中获取国际航班，按式(3)计算活动中的航班，按式(4)计算优先机场起飞的航班，按式(5)计算优先航班。Filter priority flights, obtain international flights from flight plan or 4D track, calculate active flights according to formula (3), calculate flights departing from priority airports according to formula (4), and calculate priority flights according to formula (5).
生成可用时隙资源。算法为程序控制的每个时间段生成到达时隙，小时容量为m时每个15分钟容量的分配规则见表1，不同容量值下时隙值序列的生成规则见表2，最终生成的时隙的数量恰等于流量管理中心指定的容量值。Generate available slot resources.

The generation rules of time slot value sequences under different capacity values are shown in Table 2. The final generated time slots The number of slots is exactly equal to the capacity value specified by the traffic management center.

表2 不同容量值下时隙值序列的生成规则Table 2 Generation rules of time slot value sequence under different capacity values
根据航班状态生成优先级不同的五组航班。航班按状态分组：第一组：优先航班。第二组：已经受控的航班(发生在程序修改或多个程序同时运行的情况)。第三组：没有延误的联程航班(延误判别标准：起飞时间大于原始起飞时间15分钟(含)以上)。第四组：未优先和未受控的非联程航班。第五组：有延误的联程航班。第一组航班优先级最高，第二组航班优先级次之，第三组航班优先级再次，第四组航班优先较低，第五组航班优先级最低。Generate five groups of flights with different priorities based on flight status. Flights are grouped by status: Group 1: Priority flights. Group 2: Flights already under control (occurs when procedures are modified or when multiple procedures are running simultaneously). The third group: connecting flights without delays (criterion for delays: the departure time is more than 15 minutes (inclusive) longer than the original departure time). Group 4: Non-connecting flights that are not prioritized and not controlled. Group V: Delayed connecting flights. The first group of flights has the highest priority, the second group of flights has the second priority, the third group of flights has the highest priority, the fourth group of flights has a lower priority, and the fifth group of flights has the lowest priority.
若可以得到航空公司的协同，每组内的航班都按班期时刻表到达时间先后排序。若不能得到航空公司的协同，每组内的航班按预计到达时间先后排序。预计到达时间用最新的4D航迹到达时间计算：有飞行航迹的，用飞行航迹推算预计到达时间；没有飞行航迹有计划航迹的，用计划航迹推算预计到达时间；没有计划航迹的用班期时刻表航迹推算预计到达时间。If the cooperation of airlines can be obtained, the flights in each group are sorted according to the arrival time of the flight schedule. If the coordination of the airline cannot be obtained, the flights in each group are sorted according to the estimated arrival time. The estimated time of arrival is calculated using the latest 4D track arrival time: if there is a flight track, use the flight track to calculate the estimated time of arrival; if there is no flight track and a planned track, use the planned track to calculate the estimated time of arrival; Estimated time of arrival is estimated by dead reckoning of flight schedule.
按时隙分配算法分配到达时隙或起飞时隙。该算法为优先级不同的五组航班依次分配到达时隙。第一组航班在分配时隙时被给予最高的优先权，尽量直接使用其预计到达时间占用的时隙。第二组航班拥有第二等的优先权，尽量直接使用受控的时隙。第三组航班拥有第三等的优先权，尽量使用其所在的时隙。后两组航班将最后分配时隙，从剩余的时隙中依次安排时隙，生成对应的受控到达时间。每组内的航班都按顺序尽可能使用其预计到达时间所在的时隙。时隙分配实现方法流程见图1.2，具体流程描述如下：Arrival slots or departure slots are allocated according to the slot allocation algorithm. The algorithm assigns arrival slots sequentially to five groups of flights with different priorities. The first group of flights are given the highest priority when allocating time slots, using the time slots occupied by their ETAs as directly as possible. The second group of flights has second-class priority, using the controlled slots as directly as possible. The third group of flights has third-class priority and tries to use the time slot it is in. The last two groups of flights will be assigned time slots at the end, and the time slots will be arranged sequentially from the remaining time slots to generate corresponding controlled arrival times. Flights within each group use as many time slots as possible in order, in which their ETAs are located. The flow of time slot allocation implementation method is shown in Figure 1.2, and the specific flow is described as follows:
首先判断航班预计到达时间所在的到达时隙是否被占用，若未被占用，则把该时隙分配给该航班，并使该时隙的状态变为占用状态，此航班到达时隙分配结束；若被占用，则获取或计算航班的最早到达时间。若航空公司给了航班的最早到达时间，则获取这个时间；若航空公司未给航班的最早到达时间，则由流量管理人员给其分配一个最早到达时间，一般默认最早到达时间＝预计到达时间-20分钟。得到的最早到达时间若小于控制起始时间A，则令最早到达时间＝A。然后计算当前航班最早到达时间所在时隙n，若n＜＝N，判断n时隙是否被占用，若未被占用，则把该时隙分配给该航班，并使该时隙的状态变为占用状态，此航班到达时隙分配结束：若被占用，则定位到下一个时隙n+1，然后再判断和循环。当循环到n＞N时说明没有为当前航班分配到合适的时隙，此时，强制分配最后一个时隙给该航班，用最后一个时隙的开始时间作为该航班的意图到达时间，同时滞留航班数累加1，此航班到达时隙分配结束。First judge whether the arrival time slot where the flight's estimated arrival time is located is occupied, if not occupied, then assign the time slot to the flight, and make the state of the time slot into an occupied state, and the distribution of the arrival time slot of this flight ends; If occupied, obtain or calculate the earliest arrival time of the flight. If the airline has given the earliest arrival time of the flight, this time will be obtained; if the airline has not given the earliest arrival time of the flight, the traffic management personnel will assign an earliest arrival time to it. Generally, the default earliest arrival time = estimated arrival time - 20 minutes. If the obtained earliest arrival time is less than the control start time A, set the earliest arrival time=A. Then calculate the time slot n where the earliest arrival time of the current flight is, if n<=N, judge whether the n time slot is occupied, if not occupied, then allocate the time slot to the flight, and make the state of the time slot become Occupied state, the arrival time slot allocation of this flight is over: if it is occupied, locate to the next time slot n+1, and then judge and loop. When the cycle reaches n>N, it means that no suitable time slot is allocated for the current flight. At this time, the last time slot is forcibly allocated to the flight, and the start time of the last time slot is used as the intended arrival time of the flight, while staying The number of flights is accumulated by 1, and the arrival slot allocation of this flight ends.
航班意图到达时间等于意图到达时隙的开始值，如分配到的时隙为14:24-14:27，则分配的意图到达时间为14:24。The flight's intended arrival time is equal to the start value of the intended arrival time slot. If the assigned time slot is 14:24-14:27, the assigned intended arrival time is 14:24.
活动状态指航班在飞行中或在豁免起飞时间内即将起飞的状态。若某航班处于活动状态，则只为该航班生成意图到达时间，而不生成意图起飞时间。若航班未处于活动状态，更改意图到达时间为所在时隙的开始时间。按式(6)计算航班意图起飞时间。预计飞行时间可通过最新的4D航迹计算而得：有航空公司协同的，用航空公司提供的预计飞行时间；有计划航迹的，用计划航迹计算预计飞行时间；没有计划航迹的用班期时刻表航迹计算预计飞行时间。Active status refers to the status of a flight in flight or about to depart within the exempt departure time. If a flight is active, only the intended arrival time is generated for that flight, not the intended departure time. If the flight is not active, change the intended arrival time to the start time of the slot it is in. Calculate the intended departure time of the flight according to formula (6). The estimated flight time can be calculated through the latest 4D track: if there is an airline company, use the estimated flight time provided by the airline; if there is a planned track, use the planned track to calculate the estimated flight time; if there is no planned track, use Estimated flight time is calculated from flight schedule and track.
获取需要过台间隔转换的起飞机场或起飞机场分组参数。对需要进行过台间隔转换的机场，在控制参数中获取需要进行过台间隔转换的机场MITApt。对需要进行统一间隔转换的机场分组，在控制参数中获取需要进行统一过台间隔转换的机场分组MITAptGroup。Obtain the departure airport or departure airport grouping parameters that need to be converted by station interval. For the airports that need to switch between stations, the MITApt of the airport that needs to switch between stations is obtained in the control parameters. For airport groupings that require uniform interval conversion, obtain the airport group MITAptGroup that requires uniform inter-pass interval conversion in the control parameters.
筛选受影响航班。筛选出需要进行过台间隔转换的机场(或一组机场)起飞的航班。Screen affected flights. Filter for flights departing from an airport (or group of airports) that require a step-over.
计算意图过台时间。对受影响的航班，生成意图起飞时间，根据意图起飞时间和最新4D航迹计算其对应的意图过台时间。Calculate the intent transition time. For the affected flights, the intended departure time is generated, and the corresponding intended transition time is calculated according to the intended departure time and the latest 4D track.
计算实施过台间隔起止时间。最小的意图过台时间向其所在的整15分钟向小取整，作为实施过台间隔的起始时间，如最小的意图过台时间为8:59，所在的整15分钟为8:45-8:59，则实施过台间隔的起始时间为8:45。对最大的意图过台时间向其所在的整15分钟向大取整，如最大的意图过台时间为12:18，所在的整15分钟为12:15-12:29，则实施过台间隔的终止时间为12:29。Calculate the start and end time of the implementation of the stage passing interval. The minimum intended transition time is rounded to the nearest whole 15 minutes, as the starting time of the transition interval. For example, the minimum intended transition time is 8:59, and the entire 15 minutes is 8:45- 8:59, then the starting time for the implementation of the stage-passing interval is 8:45. Round off the maximum intended transition time to the full 15 minutes where it is located. For example, the maximum intended transition time is 12:18, and the entire 15 minutes it is located is 12:15-12:29, then implement the transition interval The end time is 12:29.
划分时段并计算每个时段的过台间隔时间值。把实施过台间隔的起止时间段从前向后每个小时划分为一个时段，最后一个时段可能不够一个小时，也作为一个时段，如实施过台间隔的起止时间段为8:45-12:29，可划分为以下的四个时段：8:45-9:44，9:45-10:44，10:45-11:44，11:45-12:29。按式(7)分别计算各个时段的过台间隔时间值Divide time slots and calculate the inter-stage interval value for each time slot. Divide the start and end time period of the implementation of the interval between stations into a period from the front to the back, and the last period may be less than an hour, and it is also regarded as a period of time. For example, the start and end time period of the implementation of the interval between stations is 8:45-12:29 , can be divided into the following four periods: 8:45-9:44, 9:45-10:44, 10:45-11:44, 11:45-12:29. According to formula (7), calculate the value of the interval time between stations in each time period
优化过台间隔时间值并输出过台间隔指令。在控制时段很长的情况下，输出的过台间隔值会有许多个，这需要管制员接收每个时段的过台间隔指令，对每个时段分别进行过台间隔控制，增加了工作负荷。而在两个或多个相邻时段下，可能出现间隔值相同或相近的情况，若能保证因合并多个间隔值造成的延误时间不大于15分钟的条件，可以考虑将多个相邻时段的相同或相近的过台间隔值进行合并。如：某区域连续两个小时的过台间隔分别为20分钟/架和30分钟/架，使用算法进行合并后过台间隔转化为120/(60/20+60/30)＝24分钟/架，使这两小时内的间隔值统一化。Optimize the value of the interval time between stages and output the instruction for the interval between stages. In the case of a long control period, there will be many output interval interval values, which requires the controller to receive the interval interval instruction for each period, and control the interval interval for each period separately, which increases the workload. In two or more adjacent time periods, the interval values may be the same or similar. If it can be ensured that the delay time caused by combining multiple interval values is not greater than 15 minutes, multiple adjacent time intervals can be considered The same or similar cross-stage interval values are combined. For example: the intervals between stations in a certain area for two consecutive hours are 20 minutes/frame and 30 minutes/frame respectively, and the intervals are converted into 120/(60/20+60/30)=24 minutes/frame after the algorithm is combined , to normalize the interval values over the two hours.
分组时先从第一个间隔值开始，逐个增加后一个间隔值到组内合成新组，如果增加下一个间隔值后新组内所有间隔值对应的架次数的最大值与最小值之比小于或等于1.5，就将该间隔值并入该组，继续考察下一个间隔值；如果增加下一个间隔值后新组内所有间隔值对应的架次数的最大值与最小值之比大于1.5，从该间隔值开始再分一个组，重复刚才逐个增加间隔值合成新组的步骤，直至所有间隔值都完成分组。When grouping, start from the first interval value, and add the next interval value one by one to form a new group in the group. If the ratio of the maximum value to the minimum value of the number of sorties corresponding to all interval values in the new group after adding the next interval value is less than or equal to 1.5, merge the interval value into this group, and continue to examine the next interval value; if the ratio of the maximum value to the minimum value of the number of sorties corresponding to all interval values in the new group after adding the next interval value is greater than 1.5, start from The interval value starts to be divided into another group, and the steps of increasing the interval value one by one to form a new group are repeated until all the interval values are grouped.
1与1.5的调和平均数为：2/((1/1)+(1/1.5))＝1.2，因此有可能带来的最大延误时间为：60min×(1.2-1)＝12min。这说明我们的分组方法可以将延误时间控制在12min之内，不会产生延误时间过长的问题。The harmonic mean of 1 and 1.5 is: 2/((1/1)+(1/1.5))=1.2, so the possible maximum delay time is: 60min×(1.2-1)=12min. This shows that our grouping method can control the delay time within 12 minutes, and there will be no problem of excessive delay time.
