Abstract

Real world data is integrated into a gaming experience to influence the game and actions of a player. A game module creates game elements from the real world data associated with the location. Weather conditions are simulated based on weather information from different observation locations in the world, and traffic conditions are simulated as well. In a flight simulator game, the game integrates real aircrafts and real weather conditions as the player's aircraft navigates in the world.

Description

The integration that real time data is used to recreation

Technical field

The application relates to electronic game, relates in particular to use real world data to come the recreation of simulation match.

Background technology

In traditional computer game was experienced, the player was immersed in the enclosed environment that is driven by application developer.Even in the recreation of simulate real world position, environmental condition, participant and object (object) be by pre-defined, and only change according to predefined parameter or algorithm, or be embodied in change at random at most.Player's experience is limited in the scope that the imagination of application developer and player oneself select.Traditional game structure is only so designed the known conditions to utilize recreation to move therein, and is not designed to calculate key element new or change at random in the real world.

Traditional game makes the player can not enjoy stimulation and changeability that real world conditions provides.For example, in the flight simulator recreation, the player selects the further feature of different weather conditions, transportation condition and game environment usually.This application program produces the simulated environment that meets those parameters subsequently.Like this, traditional flight simulator can " be simulated " external data, but these data can not reflect actual current weather or transportation condition.The Add-ons bag (add-ons) of traditional flight simulator also can be carried out before starting recreation, upgrading the cloud data file of flight simulator, thereby provided the cloud coverage of real world conditions when upgrading.Yet the environment in the recreation only is updated when carrying out in advance specifically, thereby does not change during playing, and does not have the ability that the real time data of making can influence competition game (game play).On the contrary, in real world, weather can suddenly and can not expectedly change, and air traffic is crowdedly unexpectedly variable, and mechanical breakdown may occur, and the airport may be closed, and aircraft crashes once in a while, and actual pilot must adapt to these conditions.Yet these incident neither ones simulated in traditional recreation, if or they simulated, they produce in certain nonstochastic model (pattern), or occur under user's selection.Even this condition occurs in the pseudorandom model, the player will soon know the scope of possible condition, know that condition that he or she fly just therein is that " really " stimulates so it can not be enjoyed, so just caused significant difference in enjoyment aspect horizontal to the player.

Therefore, need a kind of novel recreation system, wherein can integrate real world event, environment, performer and object during game experiencing, accurate simulation that real world is experienced and the more thorniness that participates in actual real world event when actual real world event occurs be sharp to offer the player.

Summary of the invention

According to the present invention, real world information is integrated in the virtual environment that is provided with into recreation.In software product embodiment, application program module receives from player's position and selects.The geographical position of having selected wherein to play and will take place in the position, for example San Francisco.Then, application program module is fetched real world information.This real world information can according to the recreation character and difference.Play for flight simulator, real world information comprises for example Weather information and the air traffic data of cloud amount, precipitation, wind, mist, or time period near solicited message in, for selected position, comprise near the position of other aircraft that the player is, the change route and the airport condition of other aircraft.After receiving real world information, application program module generates the real world structure of the simulation of response real world information.For example, in the flight simulator recreation, these structures can comprise cloud, wind, rain and air traffic.For example, cloud produces in response position and the virtual environment as the character of determined cloud in the real world data storehouse.Air traffic, that is, and near other aircraft that player's aircraft, flies, the physical location of response real world aircraft and producing.In motor racing embodiment, the mechanical transport response of simulation on the street on corresponding real world street the real world mechanical transport and produce.Therefore,, be player's simulate real world, to provide real world intrinsic unpredictability to the player according to the present invention.

In one embodiment, application program module determines whether positional information changes after fetching last time, or whether the player has moved to reposition.If arbitrary situation changes, this model configuration responds this information and produces again, maybe this simulation tectonic response interpolator (interpolation procedure) and producing.In the time can not obtaining this information continuously, this permission is used in real world in the game environment.For example, current, can obtain air traffic information every two to three minutes, thereby the traffic that is shown to the player is interpolated till fresh information being received in the real world information database based on existing course and flight plan information.All can not obtain weather data in each position, thereby be the irrelevant position simulation weather data of those and real world data.In addition, all weather key elements of in the weather data storehouse, not describing to be described, thereby the existence of weather key element must be inferred from available data.Like this, if traffic congestion in specific certain day, then the player must fly over the congested traffic passage, if bad weather, the player must use his skill and disadvantageous weather condition to struggle, and all these all respond current actual weather or the traffic that occurs in the world of selected position.Therefore, the invention provides system, method and application program, be used for real world data is incorporated into database, to realize the ongoing game experiencing of player.

Detailed description of preferred embodiment

Though description herein uses flight simulation game to be used for explanation of the present invention as one exemplary embodiment, the invention is not restricted to this, it can easily extend to other recreation, for example outdoor ludic activity of athletics of motor racing, naval vessels contest, cycle racing, skiing or any other type.In flight simulator embodiment, two useful real world conditions that are incorporated in the recreation are weather and air traffic.Weather and air traffic data are collected by the third party and can be obtained in the public access database.This database storage is about the particular weather information of (being called " observation place ") of ad-hoc location on the All Around The World, and storage comprises the transport information of position, orientation, course and the type of aircraft.The present invention uses these information to produce stimulation, true to nature and unpredictalbe game experiencing for the player of the recreation of generation according to the present invention.

Referring to Fig. 1, game data server 108 is constantly collected " in real time " data from traffic 100 and weather 104 metadata provider systems.After receiving request, game data server 108 allows recreation 112,116 and player 120,124 to obtain data.Metadata provider 100,104 is located in remote and passes through via internet or accessed by some communication device (for example satellite or leased line).Metadata provider the 100, the 104th, traditional, and collect observation (weather, aircraft traffic etc.), and with its coding to the world, and make it obtain (just as it processed and can obtain fast) in real time with known format or structure.These data of game data server 108 accesses of the present invention also pass to database storage area with these data.To the game data server, allow from the main load of the data access of recreation 112,116 processed between recreation and game data server 108, rather than processed between recreation and the provider from " snapshot " of provider's 100,104 Data transmission.

The example of the weather data that is provided comprises temperature, wind direction and speed, in several cloud amount of highly locating and type and type of precipitation.The example of air traffic data is orientation (latitude and longitude), speed, course, identifier and flight plans of (for example in the U.S. sky) each aircraft in the geographic area.The real-time of data is relevant with the frequency that can be used for upgrading with the rate of change of the process of being monitored.Weather data upgrades by physical unit (by manpower) or electronic installation usually, for example in the METAR database, and can obtain once in one hour, and this is enough to catch the normal speed of the variation of weather condition.(under the situation of the wind of hurricane strength or extremely bad weather) under specific circumstances, weather data can be upgraded more frequently.Be in this consideration, will be envisioned for one hour in real time once, or as far as possible often with perceptible rate of change in the reflection real world.The air traffic control system of country upgraded usually once to catch orientation, course and the velocity variations of aircraft in per three minutes.This is enough fast allowing the coming orientation of interpolation aircraft according to the present invention, thereby the realistic simulation of the flight path of aircraft is provided.

When the game device in player's 120 control recreation 112, for example, aircraft, automobile etc., recreation 112 thinks that from the needed data of game data server 108 requests recreation provides environment true to nature.112 requested packets of playing are drawn together the data on the direction of the vehicles in the recreation 112 of player 120 guiding, for example weather forecast or air traffic.Therefore, recreation 112 requests are based on the current location of player device and the data of time.Temporal information can be provided clearly or implicitly.The frequency of game data request preferably meets the Data Update frequency in the database of being safeguarded by provider 100,104.This allows recreation 112 to provide the real-time depiction in the world and the vehicles in the world to the player with fast as far as possible speed.On the other hand, this request is asynchronous, and can ask mass data is used the long time.The request of data that game data server 108 is handled recreation 112 also provides the data of being asked to recreation 112, and 112 performance and simulation are used for playing.Can play games 116 different copies of a plurality of players 124, and addressable game data server 108 with obtain with another region response in the world or with player 120 data in identical zone.And second player 124 can play the recreation 112 diverse recreation of playing with first player 120 116 (for example, motor racing recreation or football game).Yet different recreation 116 can be asked the data (for example weather) with first recreation, 112 same types.Framework of the present invention can be extended to satisfy the requirement of other recreation.For example, except weather forecast, the trap for automobile competition game can produce and use the database of storage about the real time data of mechanical transport.Marine recreation can collect and store about the data of the sea condition that can use in recreation etc.

Referring to Fig. 2, game data server 108 uses from itself air traffic and weather data storehouse 200,204 of the data maintenance of aforesaid outside air traffic 100 and weather 104 metadata provider requests.Be used for requested data and the frequency that external data systems 100,104 is made in order to control, game server 108 uses 208, the 212 log-on data requests of timing processor.When starting, or any when resetting fully, timing processor 208,212 designation data requestors 216,220 all available current datas of request about weather and traffic.This data snapshot is used with beginning padding data storehouse 200,204 by Data Update program 216,220.After database 200,204 was by complete filling, then, timer 208,212 designation data requestors, 216,220 request msgs were also upgraded separately database 200,204 with the best renewal frequency that is used for independent data and time.As mentioned above, in the example of weather data, this will be integral point, and one hour once after about 10 minutes.Aloft under the situation of traffic data, this will be per approximately three minutes once.208,212 employed update times of timer and frequency is selected and optimize, thereby the update time and the frequency of matched data provider 100,104.

When player 120 plays computer games 112, this recreation will ask and position and the corresponding air traffic of the variation in the time and the weather data of player's game device.Preferably send this request of data by the air traffic 224 and weather request 228 programs of separating.Recreation 112 is to specify the form request msg of required data.For example, recreation 112 can be specified current location (latitude, longitude and height above sea level), state course and the speed of recreation aircraft in the flight simulation game.Response player's 120 selection and control input, promptly player 120 wherein and how to handle the aircraft of flight simulation in using produces the request of data of recreation 112.The game data request is used the data query that is used for corresponding traffic and weather data storehouse 200,204 with generation by air traffic requestor 224 and weather requestor 228.

For example, in one embodiment, in order to determine optimal data, requestor 224,228 is considered aircraft performance (747vs.Piper cub), state (cruise, land, take off, slide), current flight device data (orientation, course, speed and direction) and previous request (orientation, course, speed and direction).The aircraft state can be comprised by the orientation (for example, for 747 type aircraft, landing state can comprise: the speed, deceleration, aileron＞15 that are lower than 120kts) of aircraft control and the orientation of aircraft (be lower than 4000 feet and on the airport in 10 miles).

Requestor 224,228 is collected on the direction of motion of the aircraft that is suitable for the sort of aircraft and state and near frequency and distance.In making the 747 previous examples of landing, requestor 224,228 is with the data of low speed (per 10 minutes are once) request in 30 miles circumference around the aircraft because with when aircraft flies at full speed, compare, the change in location of aircraft is not frequent.During cruising condition, 747 usually 35,000 feet speed flights of going up per hour to surpass 400 miles.In this case, requestor 224,228 requests in per 5 minutes once wide be that 200 miles, length are the data in 400 miles and main long (vastmajority of length) the current course of pointing to this aircraft oval.Certainly, can use other parameter that is used for request of data according to the present invention.Therefore, the subclass of bigger database 200,204 is handled in recreation 112, and it describes the data (weather or aircraft) that recreation aircraft may run into, but has filtered orientation or the relevant data of route with aircraft.It is minimum that the data that an advantage of above-mentioned processing is the requirement Resume Mission reach, thereby saved time and bandwidth.

With regard to aircraft data, subclass can comprise a row aircraft data (for example, identifier, flight path, course, height above sea level and speed), and this row aircraft data is determined to be in the definite scope of requestor.Weather-wise, the data of returning will be included in the interior weather forecast (temperature, wind direction, dew point (freezing level), precipitation etc.) of regional extent that weather requestor algorithm is determined.Traffic and weather requestor 224,228 are because their specific needs (for example, traffic may only need in 50 miles, so that 224 work of traffic program are good, and weather program 228 may be good to work in 100 miles) may be different.

Referring to Fig. 3, games system 107 is shown, it uses OO design to realize.This special object (specialized object) preferably stores the data of himself, when needing from other object requests data and when being requested, provide data to other object.Fig. 3 illustrates traffic administration device 300, weather manager 304, aircraft manager 308, world's manager 312, colored drawing engine 3 16 and player and controls connection between 328.Because all these PROGRAMMED REQUESTS are also handled request of data from each other, when on bus architecture, they can be manifested.Other games, audio engine 320 and force feedback engine 3 24 are only obtained input from aircraft manager 308 and traffic administration device 300 by the loosely combination.

The internal database of the real-time traffic in the world that traffic administration device 300 maintenance customers experience.It is also by air traffic control device simulation movement of traffic and its control.Based on the player's type of aircraft, state and the orientation that receive from player's control/game state program 328, traffic administration device 300 will be at the traffic data in the predetermined geographic around player's aircraft from 108 requests of game data server.Data are stored in the internal database that is arranged in player's computer, and the traffic simulation that is undertaken by these requests and the internal processes by the traffic administration device upgrades this internal database continuously.

Traffic administration device 300 is handled air traffic data orientation (position, course, height above sea level, speed and the identifier) request from colored drawing engine 3 16 continuously.This colored drawing engine 3 16 is any traditional colored drawing program.These data are used to show the aircraft in the world on the recreation display.Traffic administration device 300 also can be based on the communication of aerial traffic in the real time data simulation world.This is to carry out outside the realization by the communication command that sends to audio engine 336.Based on the state of other aircraft in player and the recreation, this audio engine 336 uses these orders to give the user speech communication of air traffic control device (ATC) and aircraft (for example, from) to export voice communication information true to nature.These information comprise between ATC and other aircraft and the information between ATC and the player 120.Use conventional art known in the art to come simulated sound.

The internal database of the real-time weather in the world that weather manager 304 maintenance customers experience.Based on the player's aircraft status data (position, course, height above sea level, speed and identifier) that receives from player's control/game state program 228, weather manager 304 will be near the weather data player's the aircraft from 108 requests of game data server.These data are stored in the internal database, and this internal database upgrades continuously by these requests (based on the rate of change of weather data and aircraft movements) with by the weather simulation that carries out based on the program of weather manager rule.This weather manager 304 is handled the request from the state of weather on the wide area of colored drawing engine 3 16 (temperature, wind, precipitation, visibility) continuously.These data are used to show the real-time change weather in the world on showing the recreation display.

Weather manager 304 is also based on supplying with and rule-based program simulation weather actual, that change based on real-time weather in the weather manager 304 self, thereby provide the weather effect that can not provide from available real-time World data (for example, intensity of fitful wind, thunderstorm, cloud drift rate, all precipitation etc.).To being called as the microstage program in distance and approaching Changes in weather and trend are made a response on the time rule-based program.Macroprogram describes because the trend that every day or annual trend may occur.When the example of macroprogram comprises by day (thunderstorm tend at candlelight divide take place) or year the time (a large amount of clouds but be not that thunder cloud tends to take place winter in the U.S.) those programs of triggering.The weather that changes is shown to the user by colored drawing engine 3 16 with himself.Therefore, the use of microprogram and macroprogram has been expanded real-time world information to produce new random game condition, because their existence depends on the weather in the real world.In addition, when thunderstorm or fitful wind can have a strong impact on the pilot in flight simulation game when beam riding device or the ability that drives a car in the car racing recreation, these programs produce will with the mutual weather effect of player's recreation playability.

Microprogram

When the same day, the destiny certificate was per hour only upgraded one time, one embodiment of the present of invention micro-programming rule will be moved and be changed the World data that projects between these data of per hour upgrading once.Before receiving next update, these rule set observed data are usually along with how the time changes, and the real world data of using the simple rule designing institute developed to obtain changes in a hour of following wherein.

The wind microprogram

Direction, speed and fitful wind (for example wind is from 360, and at 10kts, fitful wind is to 20kts) are reported and be depicted as to wind.Usually per hour make to upgrade this data by each reporting post.The synoptic weather observation data of 304 current hour of the preservations of weather manager and last hour each reported position.The wind microprogram is wind direction, speed and the fitful wind value of these observations relatively, thereby changes the condition of player at the wind of next hour experience energetically.

The weather of will playing is converted to current weather observation

Next interim when new synoptic weather observation, weather manager 304 changes the player lentamente will be at the next wind of seeing in this position in 10 minutes.Though wind can change rapidly, in the quite short time, change this value and make environment more credible.In one embodiment, play 116 per minutes change direction, speed and fitful wind value about 10%.For example, suppose that the current recreation weather of position is: direction 180, speed 5, fitful wind to 10; And newly be observed direction 150, speed 10, fitful wind to 15 at time t same position.In one embodiment, the wind microprogram calculates the difference between current observation and the new observation and is:

Direction :-30 (150-180), speed :+5 (10-5) and fitful winds :+5 (15-10).

Then, the wind microprogram designed in next ten minutes, will change into the value that coupling is observed at the wind of this position.Weather manager 304 per minute in next ten minutes is carried out 1/10 (preferably being rounded to immediate integer) of variation of this design of each value.The value that the player will see will change, and will be as described below approx:

: 00 direction 180, speed 5, fitful wind 10

: 01: direction 177, speed 5, fitful wind 10

: 02 direction 174, speed 6, fitful wind 11

: 03 direction 171, speed 6, fitful wind 11

: 04 direction 168, speed 7, fitful wind 12

…… \

: 10 directions 150, speed 10, fitful wind 15

The design weather outlook

After recreation weather tapered to 10 fens clock times of the value of mating actual weather, the recreation microprogram proceeded with one's work so that weather is changing in the remaining time in this hour on the trend direction of being felt.The change at random in this excursion is calculated in the observation of the relatively current weather observation of this program, previous report, then makes Changes in weather to mate this variation in the remaining time of this hour.

For example, the observation in the position that time t-1 is reported can be: direction: 200, and speed 5, fitful wind to 10; The observation of the same position of being reported at time t can be: direction 150, speed 10, fitful wind to 15.Then, this wind microprogram calculates the difference between two observations: direction :-50 (150-200), speed+5 (10-5) and fitful wind+5 (15-10).Then, this wind microprogram is selected random value (for example-20,3,2) in excursion, and this value is added to current weather value, causes the weather of following design: direction: 120, and speed 13, fitful wind 17.Weather manager 300 is preferred per carried out in 10 minutes this design variation 20%, till next hour renewal.This changes may be as described below:

: 10 directions 150, speed 10, fitful wind 15

: 20: direction 146, speed 10, fitful wind 15

: 30 directions 142, speed 11, fitful wind 16

: 40 directions 138, speed 11, fitful wind 16

: 50 directions 134, speed 12, fitful wind 17

: 60 directions 130, speed 13, fitful wind 17

Therefore, the present invention is based on real world conditions uses the wind microprogram to produce the weather effect energetically with the control game experiencing.

Macroprogram

As described in beginning, in the time that does not have data, microprogram work is to fill or design data.Work in their time between Data Update.On the other hand, macroprogram is worked fairly largely, information being added to the weather data that has information, but with simulation needed compare not too detailed.

The frequency of thunderstorm macroprogram

In one embodiment, macroprogram is used to the thunderstorm frequency in the estimation region.The thunderstorm that may exist and seriousness (be reported as acutely or inviolent) relatively thereof are only listed in the synoptic weather observation of specific region.In this embodiment, the present invention increases this data by using simple rule, and this simple rule is, in being designed in summer months, to have the given area of thunderstorm, exist usually than autumn or winter in more thunder cloud or unit.For example, suppose when in being reported as zone, producing the formation of cloud with thunderstorm, this program average out to, the part of each generation is 3 main level thunder clouds in the most of the time of this year.During the summer months on the Northern Hemisphere (between June and August), intensification in addition can cause more frequent and other thunderstorm.

When thunderstorm was distributed to this part, this macroprogram determined that the player is playing games month of 112.This information is easy to obtain from the many sources that comprise player's computer or from external data base.Between June and August, this program can cause the random number of twice of the thunderstorm of every given area to add basic mean value to.Like this, if the player has different experience based on practical programs, the time chien shih Changes in weather of recreation 112 response current weather data and this year.

Referring to Fig. 3, the information about player's aircraft and built-in system is handled and preserved to aircraft manager 308 once more.Aircraft manager 308 obtains control input (motion of aircraft, the control of system) from player's control program 328.Aircraft manager 308 then is connected with weather manager 304, traffic administration device 300 and world's manager 312, the real-time Weather information that this weather manager is used for influencing the aircraft operation (for example, precipitation, wind, temperature), this traffic administration device is used to provide the demonstration of the real-time traffic in the cockpit display, and this world's manager is used for navigation information and the physical message about the world.Aircraft manager 308 provides aircraft customizing messages about aircraft to colored drawing engine 3 16.If desired, aircraft manager 308 is also exported indication and is given audio engine 320 and force feedback engine 3 24, with the sound and the real time perception of simulating the aircraft of knowing known in the art.

Know the information that world's manager 312 is preserved about the physical state in the world as known in the art.This comprises the information about landform, cover plant, hydrology, building, road and navigation characteristic.World's manager 312 obtains to influence the real-time input of landform appearance (temperature, precipitation) from weather manager 304.World's manager 312 provides navigation and terrain information to traffic administration device 300 and weather manager 304.World's manager 312 also provides information to colored drawing engine 3 16.

Inside (driving cabin) and outside (landform, weather, other aircraft) state that colored drawing engine 3 16 will be played by the display 332 that uses conventional art are shown to the user.Audio engine 320 is the conventional engine that produce practical flight device, communication and the world's sound of giving the user.Based on the input from aircraft manager 308 and traffic administration device 300, it will export to the user based on the sound and the speech communication of incident by audio system 336.Example is made a response to the incident that sends to it by aircraft manager 308, by the sound (as engine noises, driving cabin switch motion or aircraft collision) of audio engine 320 generations based on incident.These sound are not the once inputs under the switch motion conditions, exactly up to reformed continuous output (under the situation that engine drums).

Audio system also produces by traffic administration device 300 and the wave audio information that can be produced by other aircraft that the user hears from air traffic control device (ATC).Exploitation in advance is used for the admissible communication phase place in recreation (for example: " turn left to the course 350 " or " having received, left to 350 ") in all orientation (ATC, dummy vehicle and player).These are placed in the database that can check by order.Can use the person of dubbing to record to be included in all words in all phase places of finishing by this position and numeral (for example, word: change, left and right, to, from, course, 0,1,2,3,4, the people that will be described the ATC controller such as 5 record).These are placed in the database that can check by orientation and speech.

When communication command is received by audio engine 320, it also has all need specify and fill the information of phase place: orientation (ATC, player, dummy vehicle), order are (for example, forward the course to), and any needs enrich the concrete data (direction a: left side, course: 350) of this phase place.Audio engine 320 then check this position phase place, check the speech data that record position for this reason, then use to be called " sewing up (stitching) " this speech data is outputed to audio tweeter with the order of phase place indication.

As knowing in the art, force feedback engine 3 24 provides force feedback information to the user by the sense of touch hardware that is included in the joystick.Response produces this feedback information from the input of aircraft manager 308.The example of this feedback comprises controlled pressure, wheel rotation vibrations, touch collision downwards or because the vibrations of aircraft engine problem.

Player's control/game state program 328 is by from user's the selection and the startup and the execution of control information control recreation, and will offer other engine about the current information of the game device controlled by the player.It also preserves the data about the state in the recreation and the world.

Joystick 340 allows the user also to provide by player's control/game state program 328 and inputs to recreation.These inputs can comprise control information (driftage, gradient and rolling), throttle (throttle) position and function selection (for example, reducing the control of gear and flank).The suitable force feedback information that the user also receives from recreation by force feedback engine 3 24.Keyboard 344 is computer keyboards of standard.The player uses the button and the grand configuration with control recreation and aircraft of coding.

Therefore, the invention provides a kind of system that is used for real world data is attached to recreation, be used for influencing player's game experiencing, the result that it provides real world weather and traffic data to play with influence in (is at random degree to real world) mode true to nature and at random.

Below description two important factors in the flight simulator of the embodiment of the invention have been described: weather engine and traffic administration device.

I. weather engine

Fig. 4 represents the relation between weather engine 400 and the weather manager 304.Weather engine 400 receives from the weather input data (observation) of weather manager 304 and same day execution current weather state computation during gas management device 304 request msgs.As mentioned above, weather manager 304 is preserved and is used for describing around the required aircraft of recreation or the weather data of the weather of any other position.In a preferred embodiment, weather engine 400 is standalone modules of carrying out the interpolation of weather simulation.When the player may play games each position of 112 and time can not obtain actual real world data the time, 112 interpolations of playing are based on the data of real world data, thus the control competition game.

Be used for preferably one group of synoptic weather observation of input of weather engine 400 with assigned address and time value.The output of weather engine 400 is the weather conditions that are used for the interpolation of any assigned address and time value.Then, when player's aircraft when a position moves to the another location, or timely when mobile when player's aircraft, weather engine 400 changes the weather of describing in the recreation reposefully, thereby experiences for player 120 provides real-time weather true to nature.In addition, weather engine 400 produces " point " weather condition that is used for most of weather key element and " environment " situation that is used for some varieties of clouds types.Weather engine 400 is incorporated in to weather factor database 404, and the attribute information that this factor database 404 stores about various weather key elements is to be used to produce the weather of interpolation.

The weather key element

Below be the exemplary inventory that is kept at the weather key element in the weather factor database 404:

● cloud: cloud is distinguished with cloud layer mutually by varieties of clouds type.The cloud regulation has following attribute: varieties of clouds type, layer end height above sea level, layer top height above sea level, density (coverage rate).

● wind: wind is by layer difference mutually, and wind is linear change between layer also.Wind regulation has following attribute: highly, direction and speed.Fitful wind and blast can be prescribed.

● visibility: but the mileage that the visibility regulation has level to see.Realize limited visibility by showing mist and mist.

● temperature: temperature is defined as degree centigrade.

● pressure: pressure is defined as millibar.

● precipitation: the precipitation of being supported is rain, snow and ice hail, and it can coexist.Precipitation is defined as density.

● thunderstorm: thunderstorm is defined as power (power).

● freeze: according to freezing that other weather key element prediction may exist, it will be described below.

● turbulent flow: predict the turbulent flow that may exist according to other weather key element.

Weather key element correlation

Observation station is one group of weather data, and it is collected in the weather data storehouse of being prepared by weather data provider 104 and reports.Some weather key elements are defined as observation station, and other key element is synthetic according to other weather key element.For example, " freezing " and " turbulent flow " is not defined as observation station, thereby its existence and grade according to other weather key element is calculated.Fig. 5 illustrates the block diagram of different key elements, its output and other key element (if the words that have) that they relied on.The different weather key element requires different outputs.For example, precipitation is described and audio frequency requiring, and it is synthesized based on cloud and temperature information.Freeze and be synthesized based on temperature and visibility key element.Yet cloud self is described, and based on the real data of given observation station, or is interpolated when the current location of game device is between observation position.

A. weather key element interpolation

The main purpose of weather interpolation is when move to another location or timely when mobile from a position, interpolation based on the weather key element of those observation positions changes weather reposefully, this observation position on time and position with the current location of player's game device and around.Following algorithm is to use the observation station with actual weather data to carry out an embodiment of temperature interpolation by time and position.

Step 1--is by the location filtering synoptic weather observation

The first step of weather interpolation is a relevant observation position of selecting to be used to interpolation.Fig. 6 illustrates circulation option program piece to select the program of observation position.All observations are stored and are program block, wherein by latitude and longitude physical block.Task is selected at the observation position of the current location of close player's aircraft on the room and time.At first, weather engine 400 is handled the piece that surrounds the aircraft position, to determine whether this piece comprises observation position.Then, if this program block does not contain observation station, then weather engine 400 is handled the program block program block on every side of observation station well, as shown in Figure 6.Yet, if there is no being positioned at the observation station of position of aircraft, the search radius value is increased to and comprises the program block nearest with current location.Weather engine 400 is then handled the next nearest program block in next passage (pass), as shown in Figure 6.When finding any observation station in passage, weather engine 400 is parked on any passage.These observation stations are used to interpolation.

Step 2--time interpolation

Second step that is used for the weather interpolation is to select relevant observation according to the current time value.For each observation of in first step, selecting, selected with (immediate minimum and maximum time are worth) observation position that the current time value is nearest.

Following situation may take place:

● all observation positions that find in step 1 all are in the past.In this case, weather engine 400 will select nearest in time observation position to be used for interpolation.

● all will be observed in future.In this example, the oldest observation is selected.

● all exist in observation following and in the past.In this case, weather engine 400 select in the past nearest observation and in the future approaching observation, and produce observation based on the interpolation of the weather key element of each observation position.In one embodiment, according to current time value and the linear observation position of selecting interpolation of selected observation time value.

Step 3--position interpolation

Then, the interpolation that produces lens location according to all observations and the position of selected in the step formerly and interpolation is observed.Fig. 7 illustrates an embodiment of described interpolation mechanism, wherein Di be between lens location and the observation #i position distance square; The normalization power of observation #i is calculated as 1/Di; The total power of normalization is calculated as non-normalized power: { S=1/D1+1/D2+1/D3 ..., and the normalization power of observation #i is calculated as and is always weighed: the non-normalized power that 1/ (Di*S) removes.

Particular case exists when one or more very approaching (Di is about 0), observation existed.In this case, the immediate observation of being undertaken by the time is selected as the observation station of lens location.

Step 4--calculates undefined key element

For selected observation position, some weather key element may not exist.In this case, after weather key element of the present invention being carried out interpolation, must calculate these values according to particular weather key element rule.For example, by normal pressure vertical temperature table calculating pressure.Precipitation, varieties of clouds type and temperature computation according to this position are frozen.

Step 5--is by the height interpolation

Some temperature key element is defined as layer (a for example cloud), but for specific camera lens height and position (wind, then temperature, freeze and turbulent flow) calculated.For these key elements, weather key element value must be done linear interpolation between immediate layer value.In addition, may make the fitful wind of wind speed and direction change at random in the preferred consideration of the calculating of certain height wind.

B. cloud interpolation

According to the present invention, in flight simulation game, also preferably be interpolated for the cloud coverage rate of key factor.In one embodiment, when moving, player's aircraft realizes the cloud object with the grid that moves.The cloud parameter is calculated according to the real world observation data, and this real world observation data is interpolated each summit of grid.Fig. 8 illustrates the cloud coverage rate and is about 2/8 cloud object grid.Each unit in the grid comprises a cloud object.The position of cloud object is at random for each unit, yet bigger cloud (bigger cloud coverage rate) has " freedom " position with less.Therefore, for covering fully, each cloud object just in time is placed in the grid vertex.Calculate the size of cloud object according to the current cloud coverage value that obtains from observation data.In one embodiment, random value is added (positive size and negative size) so that simulation more true to nature to be provided.That cloud object has corresponding initial value (seed value) to produce the cloud shape.Initial value indicates each cycle cloud will upwards turn over the quantity of ripple.Initial value preferably changes in time reposefully, thus the true change of imitation cloud shape.In addition, each cloud object has the driftage random value that does not change in time.The driftage value is specified the vertical line angulation that will turn over ripple (billow toward) with cloud.

The cloud grid generates

Generation is used for each new aircraft and is used for the cloud grid of each cloud layer.For each grid vertex (cloud object), value below when grid produces, producing:

● change in size coefficient, the change in size in the scope that changes from cloudling change in size to full-size.

● side-play amount variation coefficient (side-play amount variation), from 0 to 1 scope.

● initial initial value (initial value), from 0.0 to 255.0 scope.

The cloud grid operations that is used for mobile aircraft

Cloud grid and cloud grid ladder (Cloud Grid Step) value (cloud grid ladder) is in line.Therefore, when aircraft moves to reposition, when moving enough greatly, some mesh rows and/or be listed as deleted and new mesh row and/or row to be added be possible.In this case, mobile storage program block (be used for still existing but be moved summit) and produce new summit (cloud object) value (defined) as part formerly.

The summit value is calculated

In one embodiment, each summit value can also recomputate for each weather cycle.In this embodiment, below value is recomputated:

Size

According to calculating the cloud size in cloud coverage rate (cloud density, the value in from 0 to 1 scope) cloudlike the position of density * cloud grid ladder * change in size.The cloud size of being calculated should from 0 in the scope of cloud grid ladder.Should adjust this value in the case of overflow.

Cloud level degree

Cloud level degree is the current height at the cloud of this position.

Bias

Cloud is calculated as (cloud grid ladder-cloud size) * side-play amount from the bias of grid vertex to be changed.

Initial value

According to the value of lapse of time (time_t, second) with initial value be calculated as current initial+elapsed time * cloud _ initial _ change.(cloud _ initial _ variation is the object that is used to finely tune, and value 0.2 can be assumed that for the first time).

C. icing module

In a preferred embodiment, the present invention uses the ice-formation condition on the real time data simulated flight device.The weather effect whether this ice-formation condition produce and cause by the real time data setting but by real time data.When abominable ice-formation condition can make aircraft malfunctioning and even when falling, this ice-formation condition is still experienced player has the weather effect of direct influence.Be included in the module in the weather engine 400 when in one embodiment, freezing module.The module of should freezing obtains to determine the weather input information of icing existence and seriousness.The module of should freezing is also accepted the configuration information of aircraft, comprises the state of deicing system on the aircraft.Based on weather, aircraft configuration, aircraft orientation and pilot's action, the existence and the grade of freezing on the aircraft calculated and preserved to this icing module.Can make difference of type that its reflection freezes and seriousness and for the influence of different aircraft configuration.The output of the module of freezing is the percentage of icing maximum (0.0 to the 1.0) grade of the several key parts (deep bead, side window, wing, fuselage and engine intake) of aircraft, and these will be influenced unfriendly by freezing.These data can be used by other module in the aerocraft system model (dynamics, engine), to influence the actual change of aircraft performance and operation.These data also can be used by the colored drawing device, are shown to the user with the actual effect that will freeze (visibility of the reduction of freezing on the fuselage, Ice-glazed window).

1. icing high-grade program

In one embodiment, in highest ranking, the module cyclic representation of freezing comprises:

1. import the current state of the world and aircraft

2. calculating freezes gathers

3. calculating freezes does not gather (dissolving)

4. export the icing state of the aircraft that upgrades

5. repeat

Because whole model will be by some variablees of customer impact as input, this module preferred arrangement is used for being shown to the variation in will freezing user's speed operation.Yet when ice did not freeze or dissolves with any fast speed, once Executive Module was normally not sufficient continually as per 5 seconds.

2. common variable freezes

Control 328 from game state:

● aircraft orientation (latitude and longitude)

● aircraft height above sea level (foot)

● deep bead _ deicing _ opening (current whether operation of Boolean logic indication deep bead deicing system).

● wing _ deicing _ opening (current whether operation of Boolean logic indication wing deicing system)

● these variablees will be false (FALSE) in the aircraft that does not contain these systems.In one embodiment, can make this thrashing, so that this system can be switched off (vacation), even this user has moved to out control (very).

From weather manager 304:

● the ground _ temperature of current location

● OAT (external air temperature, out air temperature), this is to use and calculates from the vertical temperature result of calculation of the standard of/1000 feet of ground _ temperature computation (supposing the ground _ temperature of 70 degrees Fahrenheits) 3 degree, this OAT that will be created in 10,000 foot 40 degrees Fahrenheit estimates.

● cloud _ coverage rate (in the cloud coverage rate of this orientation and height above sea level).This will be in the numeral that is positioned on this height above sea level between 0 (cloudless) and 1 (covering fully) in containing the temperature rectangle of this position.

3. icing particular variables:

Following variable is preserved by icing module and can be obtained by other module.This variable can have the value between 0.0 (not having ice) and 1.0 (icing fully).

Deep bead _ freeze (the icing grade of the visible deep bead on the aircraft front portion)

● side _ window _ freeze (the icing grade on side window)

● wing _ freeze (the icing grade on the wing)

● fuselage _ freeze (the icing grade on the fuselage)

● engine _ air inlet _ freeze (the icing grade of engine intake)

Based on the platform and the configuration of aircraft, can make in these variablees each all from its change of rank to other grade.

4. freeze and handle:

The approximate of the effect of freezing on the aircraft in the real world can be used to calculate icing effect by the present invention.

I) input state data

Accessed and be read into game state and weather data in the module of freezing

Ii) calculating freezes gathers

When aircraft in visible moisture (cloud), and external air temperature (OAT) is in the temperature that moisture will freeze on contact when (in 10 degrees Fahrenheits between 30 degrees Fahrenheits), carry-on freezing accumulated on a plurality of surperficial variablees.Higher temperature will melt the ice.Under lower temperature, moisture will not melt on contact.

For example, the higher rate of gathering can be assigned to the cloud coverage rate higher than 70% coverage rate (cloud that will flow through).Because aircraft configuration and ice type or height above sea level, shown this speed can be different.

In one embodiment, following algorithm is used to calculate icing gathering.

If ((cloud coverage rate＞=.1) and (cloud coverage rate＜.7)) and

((OAT＞=10) and (OAT＜=30)) then

● deep bead _ freeze=deep bead _ freeze+.01

● side _ window _ freeze=side _ window _ freeze+.005

● wing _ freeze=wing _ freeze+.01

● fuselage _ freeze=fuselage _ freeze+.01

● engine _ air inlet _ freeze=engine _ air inlet _ freeze+.01

If (cloud coverage rate＞=.7) and

((OAT＞=10) and (OAT＜=30)) then

● deep bead _ freeze=deep bead _ freeze+.02

● side _ window _ freeze=side _ window _ freeze+.01

● wing _ freeze=wing _ freeze+.02

● fuselage _ freeze=fuselage _ freeze+.02

● engine _ air inlet _ freeze=engine _ air inlet _ freeze+.02

Iii) calculate to freeze and do not gather (owing to atmosphere or deicer melt)

Because the thawing effect that atmosphere causes

In real world, there are two kinds of methods to prevent to freeze.A kind of is to fly to zone or the height above sea level that the temperature height must be enough to melt ice.This will realize on the OAT that is higher than 32 degrees Fahrenheits.Yet though the pilot can fly out from the situation of freezing, so that ice will no longer gather, OAT may warm up inadequately and be not enough to melt ice.

A kind ofly be based on flying to the algorithm that calculates deicing than the territory, warm sector:

If (cloud _ coverage rate＜.1) and (OAT＞=32) then

● deep bead _ freeze=deep bead _ freeze-.01

● side _ window _ freeze=side _ window _ freeze-.005

● wing _ freeze=wing _ freeze-.01

● fuselage _ freeze=fuselage _ freeze-.01

● engine _ air inlet _ freeze=engine _ air inlet _ freeze-.01

Iv) owing to deicing is carried out in the use of aircraft devices

Prevent that other method of freezing is to use deicer.Deicer usually is insecure and is difficult to use consistently and effectively.If the pilot does not often irregularly use this device yet, then also may gather, so that becoming, this deicer can not melt the ice.For example, if this device does not use with sufficient deicer, then this deicing value can be set to 1/2nd of total amount.

Though deicer can move effectively, deicer can not cover the thru-flight device.Finally, because the higher frequency of gathering under the ice-formation condition, it also is possible that this deicer can not keep removing ice condition.

A kind of algorithm that uses deicer to calculate deicing is:

If deep bead _ install _ opening, then

Deep bead _ freeze=deep bead _ freeze-.01

If wing _ install _ opening, then

Wing _ freeze=wing _ freeze-.01

First algorithm simulation is because the thawing (deicing) of the ice that the enough height of temperature and aircraft do not cause at Yun Zhonger.Second algorithm simulation is being opened owing to the deep bead deicing or wing deicing is being opened and removed deicing.

Therefore, for each circulation (circulation in the recreation), this deicer will be attempted removing deicing from wing and deep bead.Yet, as mentioned above, of the present inventionly remove that ice condition is actual to provide such possibility, if promptly the pilot can not be away from the condition flight that ice is arranged, freezing to ruin this device and/or aircraft.

The output state of variable v) freezes

The output state of icing variable is made amendment by gathering and not gathering model.Composite value can be obtained by other module and external module.Some are as described below about example how to use these variablees.

A) aerocraft system model

The aerocraft system model is the conventional model of simulated flight device flight.

1. lift calculates

The lift of icing on the wing that wing is produced that gathers reduces to 1/2nd.Therefore, icing model is adjusted into the aerocraft system model as described below: lift=lift * (wing _ * .5 freezes).

2. resistance calculates

Resistance Duoed 25% when gathering of icing on wing and the fuselage amounted to and carry out than aircraft.Therefore, in this example, the aerocraft system model is adjusted to: resistance=resistance * (1+ (.125* (wing _ freeze+fuselage _ freeze)))

3. the calculating of gravity

Gathering of icing on wing and the fuselage can increase very big gravity to aircraft (for this example, more than 25%).This adjustment may be:

Aircraft _ gravity=aircraft _ gravity * (1+ (.125* (wing _ freeze+fuselage _ freeze)))

4. engine performance is calculated

Engine intake freezes can influence engine performance by the available air capacity of restriction.This adjustment may be:

Thrust=thrust-(thrust * engine _ air inlet _ freeze)

5. the calculating of the influence of the aircraft devices that causes freezing owing to fuselage

Freeze and also can influence the operation of aircraft gear, aileron and instrument and meter (being coated with ice):

If (fuselage _ freeze＞.6) then aileron _ operation=vacation;

If (fuselage _ freeze＞.7) then gear _ operation=vacation;

If (fuselage _ freeze＞.8) then static _ instrument and meter _ operation=vacation;

B) icing colored drawing model

The example of the colored drawing decision of these model influences of being frozen.This colored drawing device is shown to the user with the image of the external world and aircraft.This can comprise deep bead, side window and aircraft usually.

1. to outward appearance from deep bead

From the outside image of deep bead normally clearly.Under ice-formation condition, the amount that deep bead freezes reduces visibility.Herein, a gear aerofoil shows will be by colored drawing in advance, and shows based on the deep bead _ value of freezing.For example:

Deep bead _ instrument board=deep bead _ freeze _ instrument board [deep bead _ freeze]

2. to outward appearance from side window

The image of watching outside side window is by being thickened by the indicated window of this variable _ icing ratio.Herein, the window that freezes of a row shows and will show by colored drawing in advance and based on the window _ value of freezing.

Window _ instrument board=window _ freeze _ instrument board [window _ freeze]

C) aircraft colored drawing

The aircraft self that shows by the user is according to deep bead _ freeze, window _ freeze and the fuselage _ relevant value of freezing is modified.Describing (representation) and will be added to dummy vehicle at a plurality of actual colored drawings in advance that gather the icing effect on the grade according to the value of those variablees.When window is outwards seen and when outside scene is selected, the user will see this gathering.This will comprise a lot of arrays and calculating as implied above.

Therefore, the model that freezes uses real world data as producing with the mutual icing effect of the control of player's aircraft with according to the basis of the colored drawing of aircraft of the present invention, so that the game experiencing based on the not only true to nature but also stimulation of current and true weather condition to be provided.

II. traffic administration device

Referring to Fig. 9, traffic administration device 300 is made up of its functional several stand-alone programs of realization.All aircraft in 900 generations of traffic engine, management and the renewal player 112.Traffic engine 900 is at first from player's control/game state engine 3 28 request player aircraft data (orientation, height above sea level, course, speed and configuration).It uses the aircraft traffic of these data around the aforesaid player's aircraft of game data server 108 requests.Traffic engine 900 uses the data of returning to produce aircraft in recreation 112.Traffic engine 900 is by these data of use and management of traffic database 904, and this traffic database 904 comprises near all the movable aircraft the row player aircraft.The information that stores for each database entry generally includes the aircraft identification number, and (for example, TWA714) and unique pointer, this pointed is vacation (aircraft) and the player's aircraft object by 900 generations of traffic engine in this program subsequently.Traffic database 904 is also used with identification and access traffic object by other program in the recreation 112.

Except the aircraft inlet that increases traffic database 904, traffic engine 900 is also by removing the inlet that is positioned at now outside the player area from database 904.In one embodiment, traffic engine 900 is removed any aircraft of the report of not receiving 3 update cycles from traffic database 904.As mentioned above, receive to the renewal of database 904 for the aircraft in certain geographic area of player's aircraft.Therefore, lack and report that indication has been landed or its orientation is present from the abundant aircraft far away of player's aircraft, this aircraft is no longer relevant with player 116.

Traffic engine 900 at first produces independent ATC program 908.This ATC program 908 control dummy vehicle programs 916 and player's aircraft program 932 and with dummy vehicle program 916 and 932 communications of player's aircraft program so that ATC program 908 appears in face of the player as real ATC controller.This ATC program 908 also comprises the connection (link) to traffic database 904, so that it can use the data (for example, present speed, course and height above sea level) of all relevant aircraft.

Then, when the information about new non-player's aircraft entered traffic database 904, traffic engine 900 produced the unique dummy vehicle program 916 that is used for each non-player's aircraft.Subsequently, but become the time spent when dummy vehicle program 916, the data report that traffic engine 900 also sends on the Live Flying device upgrades to them.These data are used so that the position and the configuration of its position and configuration and Live Flying device match by dummy vehicle program 916.Each dummy vehicle program 916 is as the performance of the Live Flying device in world player 120.The dummy vehicle data comprise the data such as the orientation in the world (x orientation, y orientation, course, speed and height above sea level), aircraft identifier and state (gear orientation, aileron orientation etc.) etc.These data are stored in inside, and also can respond from for example request of data of other games of ATC program 908 and colored drawing engine 3 16 etc. and be derived.During producing, also can set up communication/control connection with ATC program 908.This connects the communication command that allows dummy vehicle program 916 and ATC program 908 to carry out communication and respond ATC program 908.By sending the voice communication that communication command is realized by 916 generations of dummy vehicle program to audio engine 320.

Traffic engine 900 also produces player's aircraft program 912, and these player's aircraft program 912 outsides are connected to player's control/game state engine 3 28 and are connected internally to ATC program 908.This allows 908 monitoring and mutual with the player of ATC program.ATC program 908 can be by being mapped to program access in player's aircraft program 912 about the information of player's aircraft and intention with data from player's control/game state engine 3 28.ATC program 908 is also preferred mutual by (player finally hears) the speech communication command and the player that send to audio engine 320.The interface that this player provides by player's control/game state engine 3 28 (control, menu and keyboard commands) response controller is also mutual with controller.

A. dummy vehicle programmed algorithm

The standalone module that each dummy vehicle program 916 preferably includes simulation performing a programme, public database and handles communication, navigation and control and rule-based decision-making.The simulation performing a programme is arranged the standalone module execution sequence.In one embodiment, after initialization, the program execution sequence is:

1. communication module (input new data and order)

2. rule-based logic module (new data is more worked)

3. navigate and control module (aircraft is moved to follow current flight device target)

4. communication module (input data and order)

5. repeat.

1. public database

Public database is used to store the report that receives from traffic engine 900, the current state of the aircraft during by logic and navigation module control and about the data (for example, the current goal of navigation and control system is) of the state of internal object and dummy vehicle self.Public database also is used to be provided for the public communication architecture of program module.To the change of this database by this module input and work.

2. communication module

All communications between communication module management dummy vehicle program 916 and other external program.Its uses public database as stores new and message or send data to the zone of external program.Data by communication module input comprise more new data from traffic engine 900, from the order of ATC program 908 and the request of data of other program.Based on the message of guiding by other module, these communication module output data are to external program.Data by communication module output comprise message to ATC program 908 and audio engine 328, upgrade to the request of data of other module and to the orientation of colored drawing engine 3 16 and other program.

3. rule-based logic module

The variable condition of response dummy vehicle and the world that changes around it, the action of rule-based logic module control dummy vehicle.When the real time data that receives when dummy vehicle changed owing to date, orientation and weather, itself and these to provide real time data that the player is experienced influential rule in playing mutual.These examples preprogrammed and action rules flexibly comprise the rule that the orientation (when being controlled by the player) of variation orientation, ATC communication and control to aircraft and player's aircraft works.For example, rule that the aircraft orientation is worked comprises needs declaration ATC program 908, and dummy vehicle is on the airport in 50 miles and prepare to land.This also will produce the audio message that will be heard by the player.

The Sample Rules of describing this behavior is:

If (x, y) distance of orientation and destination airport is less than 30 miles, then

Send (declaration _ approaching _ airport, airport _ sign, orientation, height above sea level) to the atc_ controller, and

Send (declaration _ approaching _ airport, airport _ sign, orientation, height above sea level) to audio engine.

Dummy vehicle is also made a response to the order of aircraft traffic controller.Disembark the field when enough near when this aircraft, and the ATC controller tells (vacation) aircraft to stop to advance along the path of Live Flying device, and obeys its instruction landing.This order is made a response, obeyed to dummy vehicle, inform ATC program 908 that by changing its navigation module of obeying the ATC order it has been received this order and has declared same order by audio frequency.

A kind of algorithm that obtains this behavior:

If be in _ atc_ control under=false and

Receive (course _ to _ turn left 350) from atc_ system device

Then

To be in _ be set under the atc_ control true,

Stop _ normal _ navigation,

Send (course _ to _ turn left 350) to navigation and control program,

Send (informing _ turn to a left side, course) to the atc controller,

Send (informing _ turn to a left side, course) to audio engine.

Dummy vehicle 916 also can be made a response to the mobile of player's aircraft.Dummy vehicle 916 can comprise rule-based logic, to monitor and to manage to leave any aircraft (for example, if player aircraft attempt clash into it) of beginning near it.If this situation takes place, then the rule-based logic of dummy vehicle can be indicated this aircraft to interrupt normally navigating by water, flying away from the orientation of player's aircraft and be sent complaint message to ATC.An algorithm example that obtains this behavior is:

If player _ aircraft (orientation)＜1 mile then

Stop _ normal _ navigation,

Leave (player _ aircraft (orientation)),

Send (complaint _ aircraft _ approaching) to the atc_ controller,

Send (complaint _ aircraft _ approaching) to audio frequency _ engine.

In case player's aircraft leaves dummy vehicle, following rule just allows dummy vehicle to get back to normal operation:

If player _ aircraft (orientation)＞=1 mile then

Recover _ normal _ navigation,

Send (_ aircraft _ leave) to the atc_ controller,

Send (_ aircraft _ leave) to audio frequency _ engine.

B. navigate and control

Navigation and control module comprise the functional of traditional automatic pilot.Upgrade by the report of using routine techniques to follow the tracks of to be stored in the public database, it can navigate and control dummy vehicle.Yet according to the present invention, navigation and control module can also be obeyed the navigation command of issuing it by its inner rule-based logic module or outside ATC program 908.

Navigation and control module operation report upgrade so that the aircraft orientation height above sea level of dummy vehicle, speed, course and real aircraft match.In one embodiment, when per approximately 3 minutes of report data (orientation, course, speed and height above sea level) upgrades one time by traffic engine 900 (as mentioned above), navigation and control module interpolation also produce himself data, himself data is near (approximate) the moving of aircraft between these upgrade, and it will be discussed in greater detail below.These interpolations, course, height above sea level and the speed of dummy vehicle in this position is sent to the colored drawing engine and can be obtained by other program in the recreation.

Except the moving of coupling Live Flying device, this navigation and control module can also respond the particular navigation order.These orders can be issued it by the rule-based module in inside or by ATC program 908.The example of these orders comprises:

● (to the left or to the right) forward the appointment course to.

● (descend, climb or keep) height above sea level.

● (improve or reduce) speed is to a certain value.

● directly fly to a bit (x, y orientation and height above sea level).

● remain on some place's (circumference on specific x, y orientation and height above sea level).

● close airport also lands at an airport.

● leave (a certain x, y) orientation.

● (stop, recovering) normal navigation (following report upgrades).

● permit near (Cleared for approach)

● (Cleared to land) clear to land

These command formats are simple, are easy to transplant between program, and for example, order " forwarding course 350 left to " can be expressed as (to _ a left side _ to _ course, 350).

C. navigation and average between aircraft observation

For dummy vehicle is flown in believable mode, it must smoothly shift between position report.These reports comprise course, speed, height above sea level and orientation X, the Y (latitude, longitude) that is reported.At the orientation X of the up-to-date report of the Live Flying device of its representative, Y (latitude, longitude) locates to produce dummy vehicle at first.It also produces at the height above sea level place of Live Flying device, and has the course and the air speed of this aircraft.Then this dummy vehicle is by from the orientation of using this course, speed and height above sea level " promotion " forward.By the aircraft agency with to the output of colored drawing engine 3 28 internal calculation is carried out in the variation in dummy vehicle orientation.This process proceeds to till next report (latitude, longitude, height above sea level, course and speed) of receiving from the Live Flying device.Then, dummy vehicle program 916 difference between the orientation of the orientation of dummy vehicle in 116 and Live Flying device of relatively playing.Program 916 is at first calculated and is comprised and make it more directly shift to the vector of course, speed and the change of elevation in this orientation (so that aircraft can " catch up with " position, the world of this aircraft).Then it is added to course, height above sea level and velocity vector (where the vector reflection aircraft of Live Flying device is gone) from the report of Live Flying device with this vector (use vectorial addition).Dummy vehicle program 916 then orders dummy vehicle to change route, course and speed to mate this vector.Therefore, the needed two kinds of variations of formed vector reflection are to reflect real position of aircraft and moving along actual path better.

At last, according to the present invention, this automatic pilot is programmed to carry out level and smooth turning to and shifting in course and height above sea level.This automatic pilot is managed about variation more than 30 seconds, rather than order moves to the vector variation rapidly.After dummy vehicle was stabilized in this vector place, it continued to move renewal next time up to repetitive routine along it.

D. avoid player's aircraft

In that another problem in integrated is mutual between control player's aircraft and the dummy vehicle with real time data and recreation.In one embodiment, rule is used to make dummy vehicle to have the basis of the circuit of player's control.The first, if player's aircraft in the scope of dummy vehicle and move to it rapidly, then dummy vehicle flies away from.The second, if the player is close with slower speed, then dummy vehicle stops to leave this player's aircraft.The 3rd, as long as the player is at first close with fully low speed, then this dummy vehicle allows (in the maximum magnitude) flight in its vicinity of player's aircraft.The 4th, if player's aircraft moves in maximum reserve, then dummy vehicle is attempted away from this player's aircraft flight.These rule permission player's aircraft and real-time pseudo-traffic are mutual, and do not cause collision.This player is then by slowly moving the skill that research is flown near dummy vehicle in structure.This player also attempts deliberately with the dummy vehicle collision and forces dummy vehicle to fly away from its route and collide with ground object or mountain range.In one embodiment, if dummy vehicle or dummy vehicle and player's aircraft and another object collision, then the blast of the object of collision and the section of should playing finish.

Be an embodiment who obtains the algorithm of above-mentioned rule below.

Calculate distance _{Ps is to p}(Calculating Distance _{Ps to p}) Shutdown rate _{Ps is to p}(Rate ofClosure _{Ps to p}) And avoid vectorial _{Ps is to p}(Avoidance Vector _{Ps to p})

Distance from dummy vehicle to player's aircraft be calculated as X, Y and height above sea level difference square the cubic root of summation.For each X and Y, light from 0 latitude and 0 longitude, X and Y are scaled foot from longitude, latitude.Height above sea level (A) unit is a foot.Distance _{Ps is to p}=((X _Ps-X _p) ²+ (Y _Ps-Y _p) ²+ (Z _Ps-Z _p) ²) ^1/3, wherein P represents the value from player's aircraft, PS represents the value from dummy vehicle.

By distance relatively from a computation cycles to another computation cycles _{Ps is to p}Value calculate shutdown rate _{Ps is to p}If distance _{Ps is to p}Per second calculates once, and shutdown rate that then should the time period per second will be preceding value distance _{Ps is to p (t-1)}-present worth distance _{Ps is to p (t)}For example, be 1200 feet if preceding value is 1400 feet and present worth, then shutdown rate will be 200ft/sec.

Avoid vector

In each recreation circulation, the dummy vehicle monitoring is to the distance of player's aircraft of its central point _{Ps is to p}And shutdown rate _{Ps is to p}(per second approximately once).

If distance _{Ps is to p}＜1500ft, and shutdown rate _{Ps is to p}＞=25ft/min, then dummy vehicle is incited somebody to action:

A. turn off automatic pilot (for example stopping following position report)

B. per minute sends audio message at random, " has very the aircraft near me " to the effect that.

C. leave with the speed that doubles shutdown rate and avoiding vector _{Ps is to p}Direction on player's aircraft, this shutdown rate equals 1500ft/min or aircraft performance with the maximum that allows.

This algorithm is devoted to wherein, and the player begins to make the situation of aircraft to move to dummy vehicle at a high speed.If shutdown rate _{Ps is to p}＜25ft/min and distance _{Ps is to p}＞50Ft and dummy vehicle automatic pilot are closed, and then dummy vehicle program 916 is incited somebody to action:

A. open automatic pilot.

B. reply normal navigation.

C. make dummy vehicle return its original course.

D. in one embodiment, output audio message, " certain aircraft is being formed into columns and is being flown with us " to the effect that.

This algorithm is devoted to player when and is moved to this aircraft rapidly but decelerated to the situation of suitable shutdown rate.

If distance _{Ps is to p}＜50ft, then dummy vehicle program 916 is incited somebody to action:

A. close automatic pilot (stopping to obey position report).

B. sent audio message at random in per 15 seconds, to the effect that " you lean on too closely ".

This algorithm is devoted to wherein, and the player flies the situation that begins then deliberately or move to dummy vehicle mistakenly near dummy vehicle (in formation).

If dummy vehicle and ground or be different from any object collision of player's aircraft, then

A. dummy vehicle is exported audio message at random.

B. dummy vehicle blast.

C. the recreation section finishes.

If distance _{Ps is to p}＜10ft (the expression aircraft may explode), then:

A. dummy vehicle is exported audio message at random, to the effect that " it is (that wasdumb) that makes mute ".

B. dummy vehicle blast.

C. the player aircraft also explodes.

D. the recreation section finishes.

The D.ATC programmed algorithm

ATC program 908 has the framework similar to dummy vehicle program 916.This ATC program comprises simulation performing a programme, public database and the standalone module of handling communication, rule-based decision-making.

This simulation performing a programme is arranged the execution sequence of standalone module.After initialization, the program execution sequence is:

1. communication module (input new data and order)

2. rule-based logic module (the inside and outside data of more interrogating are made a response)

3. communication module (output information and order)

4. repeat.

1. The ATC public database

The ATC public database is used to store about in control aircraft with about the data of the state of internal object and ATC program 908 self (for example be used for aircraft how controlled design).This public database also is used to be provided for the public communication architecture of other program module.By the input of this module with act on change to this database.

2. The ATC communication module

The basic operation of this communication module is similar with the basic operation of used communication module in the dummy vehicle module.All communications between this ATC communication module management ATC program 908 and other external program.It uses the zone of public database as stores new and message.Data by ATC communication module input comprise position report from dummy vehicle and player's aircraft program 912,916, from the request and the response of dummy vehicle and player's aircraft program 912,916.This ATC communication module is exported data to external program based on the message that is instructed by other module.Data by ATC communication module output comprise to the message of dummy vehicle program 916, player's aircraft program 112 and audio engine 328 with to the request of data of player and dummy vehicle program 912,916.

3. Logic module based on the ATC rule

Should be based on the reaction of the ATC program 908 of the change state of aircraft in the logic module control response world of ATC rule.908 pairs of this ATC programs are made a response by the variation of the aircraft flight that the time of playing games, orientation and weather cause, thereby the real-time response true to nature to real-time traffic and weather condition is provided.Rule set work in this module with simulation in this zone, territorial sky and the player may select effective control of the main airports that flies into.ATC program 908 with fly into this airport or mutual from the aircraft of this field takeoff.

The aircraft control of E. going home.

In 50 miles, the aircraft (dummy vehicle and player) that is destined in this airfield landing must be got in touch this ATC program 908 and be stated this intention on this airport.Dummy vehicle is from moving this work.Yet the player must manually carry out this communication.When aircraft carried out this communication, they were added into the communication that ATC program in the landing formation 908 is used these queue managements and aircraft, and adjust real-time traffic as required like that player's aircraft is entered landing in proper order.This landing formation comprises FIFO (first in first out) formation of getting in touch the aircraft that this ATC program will land.Be included in the data that are used for each aircraft in this formation comprise sequential order, be used for the identification id of this aircraft, under it is placed in control and send to initial height above sea level and the current point that is allowed that is assigned with at first during near point.

This formation is used to simulate the control close and aircraft that lands at an airport by rule-based logic.This be included near in pass control and voice command is sent to several points of this aircraft.Point, they to the position of airfield runway and the order that sends as described below:

The order that the some position sends

Aircraft is got in touch first with distance＞50 on airport and mile is proceeded at first near anchor point (IAP)

ATC

The distance that aircraft arrives IAP and airport is that 20 miles allowances are to the end near anchor point (FAF)

The distance that aircraft arrives FAF and airport is that 10 miles allowances are approaching

The distance that aircraft arrives the points of proximity and airport be 2 miles clear to land

When aircraft was controlled, their obey perception, and where they be positioned at and make it advance to the order of the ATC rule of next anchor point.Use the example of the rule of data in the formation to look like as described below:

If (from _ orientation _ airport AC1)＜=orientation (permit _ to _ anchor point) then

Transmission _ message (permit _ to _ FAF) to AC1,

Transmission allowance _ arrive _ anchor point is to FAF.

When aircraft lands, from the aircraft formation of going home, delete aircraft.As long as the data from aircraft disappear, will be by this traffic engine 900 with this aircraft deletion.

1. Aircraft is remained at first near anchor point (IAP) point.

When sailing for the heavy traffic on airport, have aircraft that specific energy holds want many aircraft want near and the number of times that lands.(once only there is an aircraft to be allowed finally near orientation (Final Approach Fix, FAF), this makes the aircraft sequence that steadily enters).This also can occur when player's aircraft is selected near this airport.Between being allowed, hold it by requiring this aircraft to remain on the ATC of IAP place program 908 finally near the orientation.

When this aircraft was allowed IAP at first, it was given the height above sea level that will keep.Use the sequential order in the formation to produce this height above sea level to determine side-play amount from basic height above sea level.This height above sea level separation prevents the aircraft collision.For example, if close aircraft is that the 4th aircraft in the formation and the basic height above sea level of IAP are 10,000 feet, then will to be allowed from this IAP be 10000+ (4*1000)=14,000 foot to this aircraft.When number of queues surpass 10 and formation in aircraft sum during less than 10 (showing that some aircraft are allowed), then this aircraft fleet columns resets to 1.This will cause next aircraft to be allowed 11, and 000ft. (10,000+1*1000ft).When the FAF clear aircraft that becomes withdraws from the next aircraft that keeps and remain on the IAP place and is allowed FAF.

2. The aircraft that flies out

When the aircraft from this airport (taking off) sent their flight-ready communication messages of expression to ATC processor 908, they were added to the formation of taking off.When they by producing and their flight plan when representing that they do not take off yet at the traffic engine on this airport 900, this message is sent automatically by dummy vehicle.When they on the airport and when not taking off yet this message also can produce by player's aircraft.This formation of taking off is allowed the ID of sequence numbering, this aircraft and they to save as data to work an anchor point that flies to.3 anchor points of logical AND that take off are relevant.

The order that locating point position sends

Aircraft is got in touch ATC first and is permitted taking off on runway

1 mile recoverys (resume) of disembarking of course number anchor point is navigated by water

Removing airport (clear of airport) disembarks times 50 miles and sends message and " wish that you spend fine one day "

When the aircraft request was taken off, this aircraft was added to the formation of taking off.If it is safe (any aircraft formerly arrived or left or from the course number anchor point) that ATC program 908 allows aircraft takeoff, then this aircraft is allowed to take off.Otherwise this aircraft is required to keep, and is allowed to take off when this anchor point becomes unimpeded.In case it arrives this positioned in sequence point, ATC program 908 send order to aircraft recovering normal course, but this aircraft is not removed from this formation.Then this aircraft can begin to obey its report data and match with real aircraft routes.When moving to 50 miles anchor points, it is removed and is sent the sense of hearing from this formation and is sent message.

3. Aircraft is kept on the ground

When in the landing formation, the aircraft that can exist specific energy to hold wants many aircraft to want the situation of taking off.This usually occurs in when the requirement of player's aircraft is taken off when the airport is busy.In this case, when this aircraft sends flight-ready message, indicate this aircraft to keep.When the front of aircraft in the formation of leaving, this aircraft finally is allowed to take off.Number of vehicles to the formation that can keep taking off is unrestricted, and this has reflected real-life unfortunately.

4. Tackle rascal's aircraft

The landing and the formation of taking off also play second purpose, allow the not territorial sky of the aircraft (especially player's aircraft) under its control of ATC program 908 monitoring.If ATC program 908 determines that player's aircraft are in 50 mile range of disembarking and do not get in touch ATC program 908 and have been placed in the landing formation, then ATC program 908 will be by sending audio message to this unknown aircraft, require it to discern himself and its objective is what or similar message, land up to this aircraft with inquiry.Proceed on the runway and failed call is permitted and taken off if they do not require, then same program is used to this player's aircraft.These ATC program 908 perception its on runway, and request is permitted taking off (not in the formation of taking off), and will send suitable audio message string, up to this aircraft to 50 miles outside.

5. The use of weather data in real time

This ATC program 908 also can be used in the airport that it is being controlled with aforesaid real-time weather data, with the request (for example, wind direction how) of response pilot to weather data.These data also are used to allow the optimal runway of ATC program 908 select command aircraft lands, and produce true to nature the describing of CN part self based on real-time conditions.

Therefore, system, method and the device that is used to allow to use real time data influence and driving game experiencing described.Though described in detail preferred embodiment, flight simulation is used, teaching of the present invention also can be extended other recreation, for example automobile and naval vessels game, or other competitive sports.Can make many other modifications to as above device, and not depart from true spirit of the present invention.In addition, though the different step of said method and the module of foregoing circuit have been carried out the description of particular functionality, these functional order that can be different are realized with the disparate modules that those of ordinary skill in the art knew.
