Description

Technical Field

[0001] The invention belongs to air traffic control system technology, and in particular relates to a modeled open air traffic control operation simulation system and method. Background Art

[0002] With the rapid development of the aviation transportation industry, the number of flights and the complexity of operations continue to increase, which has brought many challenges to air traffic management. How to ensure the efficient and safe operation of air traffic is the current focus of attention. On the one hand, through the reasonable planning of the air traffic control operation environment (including routes, airspace, etc.), the optimization and adjustment of operation rules and strategies, on the other hand, through technical means to improve the auxiliary decision-making ability, such as the optimization of the algorithms such as the approach and departure sequence and the allocation of aircraft positions, in order to improve the overall efficiency. The verification of the scheme adjustment and algorithm optimization is generally achieved by simulation. The main simulation systems and methods currently used include: first, integrating business systems to form a simulation environment, using the simulation method of man in the loop; second, using foreign commercial fast simulation software or customizing algorithm-level verification programs for specific simulation verification needs for digital simulation. The human-in-the-loop simulation method has high requirements for equipment and personnel, and requires a large number of personnel and equipment to participate in verification, which is complex and costly. The digital simulation method uses foreign commercial software, whose model algorithm is relatively fixed, and it is impossible to replace a certain algorithm model for technical verification. It has poor flexibility and openness, and the application scenario of algorithm-level customization is relatively single. The system is customized and developed according to specific verification requirements, and the algorithm model has poor reusability and weak versatility. Therefore, there is an urgent need for an air traffic control simulation system and method that is open and modeled, and can flexibly load and replace models according to simulation verification requirements. Summary of the invention

The data set association list DSL is described as: DSL = {(C 1 ,DS 1 ),(C 2 ,DS 2 ),...,(C m ,DS m )}

[0021] Where m is the number of current data sets, (C m,DS m ) is the index relationship of the mth data set, C m is the unique identifier of the mth data set, DS m is the storage index of the mth data set.

[0031] Step 1-2: register the model's concerned events with the simulation controller, register the simulation and playback timing messages, and the simulation controller searches for the concerned event E in the business event registry REGT. n Does it already exist? If it does, further determine event E n Corresponding business simulation model sequence RL nIs this model already included? If not, then n Add this model in the event registry REGT. If the event E of interest is not found in the event registry REGT, n , then dynamically increase the event E n and model sequence (E n ,RL n ), and add this model to RL n middle.

[0048] Taking the airport flight zone air traffic control operation simulation as an example, a modeled open air traffic control operation simulation system and method are specifically described in conjunction with the accompanying drawings.

[0049] 1. Figure 1 This is a composition diagram of the air traffic control operation simulation system designed in the embodiment of the present invention, including a simulation monitoring controller, an air traffic control environment modeling module, an operation rule setting module, a simulation plan generation module, a simulation resource database, a simulation deduction controller, a business simulation model group, a data sharing service, and an evaluation and analysis module.

[0050] The simulation monitoring controller provides functions such as unified management of simulation schemes, unified control of simulation progress, and visual monitoring of simulation situations. The air traffic control environment modeling module provides modeling functions for basic elements of the simulation environment, including waypoints, air routes, approach and departure routes, control sectors, airports, runways, taxiways, parking stands, and taxiway key points.

[0051] The operation rule setting module provides the configuration function of simulation rules. The configured rules include: runway operation rules, parking stand usage rules, taxiway operation rules, sector transfer rules, and waypoint passing interval rules.

[0052] The runway operation rules description structure is defined as follows:

[0053] Physical runway code, such as "06-24";

[0054] Logical runway code, such as "06", indicates the direction of runway operation;

[0055] Runway takeoff and landing attributes, such as "AD", indicate whether the runway is used for takeoff, landing, or both;

[0056] The separation requirement of take-off and landing aircraft is described by a separation rule array set, and the separation rule array set is described as: IR = {(FP 1 ,NP 1 ,FT 1 ,NT 1 ,dis 1 ),(FP 2 ,NP 2 ,FT 2 ,NT 2 ,dis 2 ),...(FP n ,NP n ,FT n ,NT n ,dis n )}, where FP is the leading aircraft model, NP is the trailing aircraft model, FT is the leading aircraft take-off and landing mark, such as "A" represents a landing flight, "D" represents a take-off flight, NT is the trailing aircraft take-off and landing mark, and dis is the interval requirement under the leading and trailing aircraft mode.

[0057] The structure of the parking space usage rule is as follows:

[0058] Aircraft station code, such as "56";

[0059] The suitable stop model requirement is described by a suitable stop model array set. The suitable stop model array set is described as: PR = {PT 1 ,PT 2 ,...,PT n}, where PT is the specific model code, such as "A320";

[0060] Suitable stop airline requirements are described by a suitable stop airline array set, and the suitable stop airline array set is described as: AR = {AC 1 ,AC 2 ,...,AC n}, where AC is the airline code, such as "CCA";

[0061] The taxiway operation rules description structure is as follows:

[0062] Taxiway code, such as "D5";

[0063] The taxiway key point sequence is described by a taxiway key point array set, and the taxiway key point array set is described as: TP = {P 1 ,P 2 ,...,P n}, where P is the key point code of the taxiway;

[0064] Taxi direction signs, such as "B" for two-way traffic, "F" for forward one-way traffic, and "R" for reverse one-way traffic;

[0065] Taxiing speed limit; the unit is kilometers per hour, such as 60;

[0066] Model restrictions, described as a model array collection.

[0067] The simulation plan generation module provides the function of making the flight plan to be simulated. The flight plan making methods include: manual interactive making and batch making based on city pairs.

[0068] The simulation resource database is used to store simulation schemes and simulation evaluation information and provide data services. The simulation deduction controller provides unified scheduling management functions for the business simulation model group, receives business event registration messages of simulation models in the business simulation model group, and maintains the business event registration table; receives control information from the simulation monitoring controller, distributes simulation control information and deduction and playback timing information to the business simulation model group; provides routing control functions for business event information, and performs routing forwarding of business event information according to the business event registration relationship in the business simulation model group, thereby realizing unified routing management of event information, avoiding direct interaction between business simulation models, reducing coupling between models, and providing a basis for flexible configuration of models. According to the needs of the airport flight zone air traffic control operation simulation in the embodiment, the business simulation model group mainly includes a tower controller model, an approach controller model, an aircraft model, a stand allocation model, and a control system model. Each simulation model can be mounted to the simulation deduction controller by model registration, and can receive control information, timing information, and business event information pushed by the simulation deduction controller. The data sharing service provides the function of memory data sharing between models within the business simulation model group. The evaluation and analysis module provides the functions of evaluation and analysis of simulation results and visual display of evaluation.

[0069] 2. The simulation monitoring controller, air traffic control environment modeling module, operation rule setting module, simulation plan generation module, and evaluation and analysis module are deployed on the client side, among which the evaluation and analysis module is deployed independently, and the air traffic control environment modeling module, operation rule setting module, and simulation plan generation module are deployed in the form of a dynamic library under the simulation monitoring controller; the simulation resource database, simulation deduction controller, business simulation model group, and data sharing service are deployed on the server side, among which the simulation resource database is deployed independently, and the business simulation model group and data sharing service are deployed in the form of a dynamic library under the simulation deduction controller. Since the business simulation model group and data sharing service are deployed in the form of a dynamic library under the simulation deduction controller, it provides a basis for memory-level data sharing between models.

[0070] 3. The simulation controller interacts with the simulation monitoring controller through network messages to exchange control information, uses the simulation resource database to exchange initial data information, and interacts with the business simulation model group through API messages. Only the simulation controller and the simulation monitoring controller interact through network messages, and the main information exchanged between the two is control information, which greatly reduces the pressure of network communication. The simulation controller and the business model group interact through API information and synchronous control in the process, avoiding the problem of simulation timing control between model groups in asynchronous mode.

[0071] 4. The simulation controller contains a model configuration XML file, which is used to configure the business simulation model to be loaded. Through configuration, the business simulation model involved in the simulation can be flexibly loaded, removed and replaced. The specific content of the model configuration XML file includes the model name and model path.

[0072] 5. Data sharing service provides API interfaces for creating and acquiring data sets and reading data in data sets. Data sharing provided by third parties through data sharing service avoids the coupling of direct information retrieval between models, further decouples business simulation models, and provides the possibility for reuse and flexible loading and replacement of simulation models.

[0073] 6. Figure 2 It is a flow chart of the air traffic control operation simulation method in an embodiment of the present invention.

[0074] The first step is to determine the models in the business simulation model group according to the airport flight area air traffic control operation simulation requirements of this embodiment, including: tower controller model, approach controller model, aircraft model, stand allocation model and control system model. According to the business logic needs of each model, the required data sets are created, including the aircraft model to create an aircraft situation data set, the stand allocation model to create a stand usage status data set, and the control system to create a plan information data set. All data sets are published and shared through data sharing services. At the same time, each simulation model registers the event messages that the model is concerned about, as well as the deduction and playback timing messages, to the simulation deduction controller through a standardized interface, such as the aircraft model registering the control instruction to publish the event message, and the event message type is represented in the form of a string.

[0075] The second step is to configure the model configuration file, modify the XML file, and configure the model participating in this simulation in the business simulation model group, as follows.

[0076] <modules>

[0077] <Module Name="Tower Controller Model", Path="E:\Modules\TowerController.dll" / >

[0078] <Module Name="Approach Controller Model", Path="E:\Modules\ApproachController.dll" / >

[0081] <Module Name="ATC System Model", Path="E:\Modules\ATCModule.dll" / >

[0082] < / modules>

[0083] The third step is to build a simulation environment, set operation rules, and formulate a simulation plan through the air traffic control environment modeling module, operation rule setting module, and simulation plan generation module. Figure 3 The figure shows the simulation environment and rule design of the flight area of ​​Lukou Airport. The simulation environment includes the configuration and connection relationship of the airport runway, aircraft stand, and taxiway. The runway operation rule is set as runway 06 for takeoff and runway 07 for landing. The taxiway taxiing rule is set in combination with the runway operation direction (based on the Figure 3 Taking the two taxiways P1-P2 and P3-P4 shown as examples, P1-P2 is a two-way taxiway, P3-P4 is a one-way taxiway, and the taxiing direction is from P3 to P4), and based on the flight schedule of Lukou Airport, a one-day flight plan is batch generated as a simulation plan. Some plan information is shown in Table 1 below.

[0084] Table 1

[0085] Flight number Planned departure time Departure Airport Destination Airport Aircraft registration number model CES2941 8:00 JbXj RCMQ B1636 A320 DKH1675 8:05 JbXj ZYTX B9978 B738 CES2773 8:08 ZYTL JbXj B6759 B738 CES2862 8:10 JbXj ZB B2220 A320 CSN6452 8:13 ZUGY JbXj B6191 A319 CES2755 8:16 JbXj ZPPP B6472 A319 CSC8840 8:18 ZY JbXj B1887 A320 CSZ9573 8:20 JbXj ZUGY B5618 B738 CSN3699 8:22 ZGGG JbXj B6292 A320 JYH1039 8:25 JbXj ZY B1716 B738 … … … … … …

[0086] The fourth step is to start the fast simulation. The simulation controller schedules the control business simulation model group and the data sharing service to complete the simulation scenario simulation driven by time sequence and events, and records the key information data of the simulation process into the simulation resource database.

[0087] The fifth step is to periodically obtain the current simulation plan from the simulation resource database, obtain the key information of the plan based on the current simulation plan, and statistically analyze and visualize the analysis results. The statistical analysis includes: average taxi time, average taxi distance, the number of taxi conflicts mediated by the controller per unit time, the average taxi waiting time of flights, and the number of parking conflicts.

[0088] The sixth step is to start the simulation playback through the simulation monitoring controller to visually playback the simulation process.

[0089] 7. Figure 4 The following is a flow chart of the simulation of the business simulation model group based on timing and event-driven deduction in the embodiment of the present invention. The horizontal arrows represent the timing and event-driven deduction process, where the dotted arrows are event-driven and the solid arrows are timing-driven. The event-driven between models is forwarded and pushed to the event-focused party through the simulation deduction controller, thereby reducing the direct interaction between models and achieving low coupling.

[0090] In the first step, the simulation deduction controller receives the start simulation information pushed by the simulation monitoring controller, and pushes the start simulation to each business simulation model in the business simulation model group in the form of an event;

[0091] In the second step, after receiving the simulation start event information, the control system model obtains the air traffic control environment modeling information, operation rule information and simulation plan information of the scheme from the simulation resource database according to the current simulation scheme ID, and initializes the data information in the shared data set;

[0092] In the third step, the simulation controller pushes the timing information with a 1-second logic timing step, drives the status update of each business simulation model timing, and records the status change information during the business logic processing. Figure 4 Take the aircraft model in as an example, when the timing signal is received, the aircraft model is triggered to calculate the change of the aircraft position and attitude under the 1-second timing step and record it;

[0093] Step 4: If a business event is triggered during the business logic processing of the business simulation model (business logic processing includes business logic processing triggered by time drive, such as Figure 4The control instruction release event message launched by the middle tower controller model, as well as the logical processing triggered by the event, such as Figure 4 the receive or reject event message pushed by the middle tower controller model), the business event will be pushed to the simulation deduction controller. The simulation deduction controller will hand over the event to the corresponding model according to the business event registration table. Otherwise, execute the third step until the deduction time sequence ends. Taking the control instruction release event message launched by the tower controller model as an example, this event message needs to be received and processed by the aircraft model. However, in this method, it is not directly pushed from the tower controller model to the aircraft model, but pushed to the simulation deduction controller. The simulation deduction controller searches the business event registration table and then routes and forwards it to the aircraft model. Due to such processing, the tower controller model and the aircraft model do not need to pay attention to each other's existence, but only need to pay attention to the event messages that are required and can be pushed, realizing low coupling between models and providing the possibility for the model openness of the simulation system.

[0094] Embodiment 2:

[0095] Based on Embodiment 1, adjust the usage of the airport runway. Set the runway operation rule as taking off from Runway 07 and landing on Runway 06 through the operation rule setting module of the client. Reuse other steps in Embodiment 1, view the evaluation and analysis index data output by the evaluation and analysis module, and compare it with the simulation evaluation index data in the case of the runway operation mode of taking off from Runway 06 and landing on Runway 07 in Embodiment 1. The average taxiing time in Embodiment 2 is 20% less than that in Embodiment 1. Thus, the comparison and verification of different operation schemes are realized by means of a model-based open ATC operation simulation system and method proposed by the present invention.

[0096] Embodiment 3:

[0097] Based on Embodiment 1, replace the used stand allocation model with the stand allocation model described in the patent "A Real-Time Flexible Stand Scheduling Method and Scheduling System for Optimizing Throughput" (ZL201910362225.4), as shown below, where NewStandAss.dll is the stand allocation model using this patent method.

[0098] <Module Name="stand allocation model to be verified",Path="E:\Modules\NewStandAss.dll" / >

[0099] By reusing the other steps in Example 1 and increasing the simulation plan, compared with the simulation evaluation index data of Example 1 using the first-come-first-served aircraft stand allocation model, the aircraft stand allocation method of Example 2 has a 10% higher throughput per unit time than that of Example 1, thereby conveniently realizing the verification of new technologies and new algorithms with the help of a modeled open air traffic control operation simulation system and method proposed in the present invention.

[0100] The present invention provides a modeled open air traffic control operation simulation system and method. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention.
