The various systems that provide warning and early warning to indicate under the hazardous flight state all are known.The known ground anti-collision alarm system that is used for aircraft is arranged in these systems, and the state of flight of this system monitoring aircraft if state of flight is because carelessness is about to and ground collision, is just reported to the police immediately.Use the state of flight of this system monitoring that wireless electrometric flying height and rate of change, the height of air pressure and the position of rate of change, flying speed and wing flap and undercarriage are arranged.Above-mentioned parameter is monitored, when above-mentioned state or the relation between the parameter express possibility and ground when colliding, produce the early warning indication or report to the police.The instantiation of this type systematic in being 3715718,3936796,3958218,3944968,3947808,3947810,3934221,3958219,3925751,3934222,4060793,4030065,4215334 and 4319218 United States Patent (USP), the patent No. is disclosed.All these patents are the same with the present invention, all transfer same assignee.
Under subaerial situation, said system provides early warning and alerting signal, reports to the police but this type systematic only relies on the state of flight of aircraft to produce merely, and does not utilize navigation information.Therefore the sensitivity of this type systematic must be adjusted, so that the type of landform below during regardless of aircraft flight, when the hazardous flight state occurring, can both provide sufficient warning, and when being safe from danger, can not produce false alarm wrong or that cause the trouble accident.For the standard that optimization under the different terrain situation is reported to the police, the standard of warning must be adjusted as the function of landform.In a kind of system, this adjustment is revised the warning state of flight according to landform and is finished, and this landform is unique when aircraft flies over specific geographic area.Open in the patented claim of awaiting the reply that this system is 06/560073 in sequence number, the applying date is Dec 9 nineteen eighty-three, U.S. Patent number is now, equally with the application transfers same assignee.
In the system of just having narrated, global terrain data all is stored in the nonvolatile memory of the separation in the aircraft.The navigational system of aircraft is determined the position of aircraft.Positional information is input to warning system, and corresponding specific terrain data correction warning and early warning system, and the geographic area that these data are being flown over for aircraft is unique.Because aircraft can fly under the sun, therefore need in the storer of aircraft, store global terrain data.Though the whole world is subdivided into less zone, and terrain data to be all being that optimized mode is stored for each zone, but needs a large amount of memory storage space.The terrain data of storing in the map mode according to using needs 1 megabit sotrage spare more than 10.This device is each about power consumption 400 milliwatt when static state.4 watts of the about power consumptions of system of 10 this devices are arranged.Therefore this only represents the main part of warning system power consumption, has seriously limited the power consumption that the parts of microprocessor and other and memory device collaborative work can allow.Thereby the power consumption that need provide a kind of device to remove to reduce the memory device that links to each other with warning system with the early warning of aircraft, the alarm criteria of this system are as the function of terrain data and set up or change.
Therefore, an object of the present invention is to provide a kind of accumulator system of using in the aircraft measurement system, this system has overcome many shortcomings of prior art accumulator system.
Another object of the present invention provides and is used for that aircraft is reported to the police and the early warning system storer of graphic data accordingly, and this storer has overcome the shortcoming of big power consumption.
Another object of the present invention is that the whole world is divided into the geographic area, and each zone is stored in the mode of map with ad hoc approach, thereby only needs the part device in whole memory devices to power in the given time.
A further object of the invention is selectively to the memory device power supply, to reduce the power consumption of whole accumulator system according to specific geographic area.
In brief, the illustrated embodiments according to the present invention, the whole world or related geographic area are subdivided into several zones, and these zones further are subdivided into latitude zone and longitude zone again.The data of determining terrain feature in these zones deposit carry-on accumulator system in the map mode.In illustrated embodiments, the terrain data in a corresponding zone deposits in the memory device of storage system in the map mode.Therefore that is specific when regional when aircraft flies over, and only powers to that specific memory device.Other memory device that contains corresponding other regional data is not then powered, in fact make its power consumption reduce to zero.In arbitrary specific time, all the power consumption of memory device equals the power consumption of a device in fact like this, has therefore greatly reduced the microprocessor load.
By following detailed description and accompanying drawing, can find out these and other purpose of the present invention and advantage significantly.
Fig. 1 shows the world map that system according to the present invention is divided into a plurality of geographic areas.
Fig. 2 shows the functional-block diagram of storage system according to the invention.
Fig. 3 is to use the functional-block diagram of aircraft warning system of the present invention.
Although embodiments of the invention can have multiple different form, illustrate in the drawings, and what will describe in detail is most preferred embodiment of the present invention.Must be pointed out that content disclosed herein only is the principle that illustrates invention, rather than on the specific embodiment of wanting invention is confined to exemplify.
Referring to Fig. 1, the whole world or the geographic area that relates to are divided into a plurality of zones.In Fig. 1, be divided into 16 independent zones.These zones are rendered as the rectangle of different sizes.These areas or zone and big or small selection thereof depend on that the included danger that can cause the aircraft that leaps the regional sky in these zones maybe needs to revise the terrain feature of warning state of flight.As shown in the figure, regional with specific longitude zone and latitude zone are corresponding.For example zone 8 is corresponding with east longitude 0-15 ° and north latitude 0-90 °.
As can be seen from Figure 1, the whole world can be divided into the rectangular region of different sizes.Area or a zone with related lineament of a large amount of intensive appearance, for example less geographic area is generally occupied than the area or the zone of relatively flat in the mountain area.As can be seen from the figure, the Minimum Area shown in the corresponding region 5, it comprises that longitude is 15 ° and latitude is 45 ° a scope.It can also be seen that from figure corresponding region 2,3,4,5,6,8 and 9 minimum latitude zone are 15 °.The zone of the minimum longitude zone of corresponding 30 ° of longitude scopes is zones 12.Though the whole world shown in the figure is divided into 16 zones, any number that puts the zone under all belongs to protection scope of the present invention.Therefore imagined the width in longitude zone and latitude zone or size can than illustrated bigger or smaller.For example sequence number is 06/560073, the applying date is that Dec 9 nineteen eighty-three and the present invention have in same assignee's the patented claim of awaiting the reply, and the latitude zone further is subdivided into a plurality of areas, and the area further is subdivided into the zone.Whether needs change in warning system decides the size in area or zone according to the terrain feature of this geographic area.
The regional terrain data of shown in Figure 1 each deposits the storage system of representing with total label 10 shown in figure 2 in the map mode, and this system comprises a plurality of each memory device of all representing with label 20 respectively.In most preferred embodiment, it is that storer 20 is denoted as 20-1 to 20-16 in illustrated embodiment in one of memory device of 20 that corresponding each regional terrain data shown in Figure 1 deposits 16 labels in the map mode respectively.Therefore the geographic area 1 to 16 shown in the terrain data difference corresponding diagram 1 that comprises among the memory device 20-1 to 20-16.Though 16 memory devices are shown, the specific dividing mode and the number of division when being to use how much depending on of memory device that the whole world is divided into the geographic area here.For example, if aircraft does not fly in worldwide, the terrain data of the specific geographical area that only relates in such example need deposit the storage system of aircraft in the map mode in, and need not all deposit global terrain data in the map mode storage system of aircraft.Determine the terrain data of this specific region, for example may only need 5 to 10 memory devices.This situation also is considered to belong to protection scope of the present invention.
A plurality of memory device 20 shown in Figure 2, switch 30 and a code translator 40.As shown in the figure, each memory device all has the memory capacity of 1 megabit.For access is carried out in 100 ten thousand memory locations that exist in each such memory device, just require microprocessor to use 20 bit address (not illustrating in the drawings) at least.Use is less than 20 address, then will make some memory locations in each memory device become and can't address.Therefore not each all link to each other (not the illustrating in the drawings) in 16 memory devices shown in 20 bit address lines of microprocessor.In illustrated system, owing to need 20 bit address at least, this just needs 16 microprocessor, and this microprocessor has 24 bit address buses and 32 bit address registers, for example Motorola M68000.Can link on each memory device, can carry out access to all memory locations like this for 20 in the 24 bit address lines.Though 20 bit address lines are only represented to be connected on the memory device 20-13 in the drawings, it should be understood that to be that 20 bit address lines can be connected on each memory device.
Illustrated memory device must be non-volatile, because if use volatile storage spare, terrain datas a large amount of when memory device cuts off the power supply will lose.And because terrain feature keeps constant relatively, what need to change only is that therefore use ROM (read-only memory) shown in Figure 2 (ROMS) is as the memory device that separates because disaster or construction of buildings artificially take place.Various memory devices comprise that programmable read only memory (PROMS), ultraviolet-erasable programmable read o (EPROMS), EEPROM (Electrically Erasable Programmable Read Only Memo) (EEPROMS) can be used as memory device 20.Invention further it is also conceivable that uses " shadow random access memory " commonly known in the art (shadow RAMS).The shadow random access memory is a kind of random access memory of easy mistake, but it has a kind of non-volatile backing memory, for example EPROM.Use term ROM explanation the present invention below, comprise ROMS, EPROMS, EEPROMS and shadow RAMS but be interpreted as this term.
Each ROM20 comprises the pin of these memory device input and output of a plurality of connections.One in these pins is used for powering to memory device.This pin is shown in Figure 2, and represents with P.As shown in the figure, the pin P of each ROM with link to each other with 30 switches of representing, this switch preferably makes field-effect transistors (FET) switch.The required power supply of ROM operate as normal is also received on each switch.Shown in the figure 5 volts of direct supplys.
As previously mentioned, the ROM of each power supply is more than about power consumption 400 milliwatts of static state.In system shown in Figure 2, the total power consumption that is used for 16 memory devices is approximately 6.4 watts.This will take the alarm computer with 2 storage control devices (MCU) scale and assemble 1/3 of the interior safe power consumption general power that is allowed of limited field, therefore seriously restrict design.
In disclosed system, each device can be powered separately, simultaneously other device outage.For example, if aircraft 4 overhead flights in the zone just only give device 4 power supplies.By switch 30 remaining device and power supply are disconnected.Because aircraft at any one time only can be a zone flight, so this only need a memory device power supply a moment just to have determined.The maximum power dissipation of whole storage system will be limited to the power consumption of a memory device.In the illustrated case, power consumption is reduced to 1/16.
If desired, can address each memory device 20.As previously mentioned, use the storer of 1 megabit to need to use 20 bit address lines to address at least to all utilizable memory locations of each memory device.So at least, need 16 microprocessor of 24 bit address buses and 32 bit address registers.Because 20 bit address lines are used for the memory location of memory device is addressed, so 4 left address wires address each independent memory device with regard to being used for.20 low order address lines, for example A1 to A20 should link to each other with each independent storer 20, and is used for the memory location of these memory devices is addressed.Remaining next address wire is used for each memory device is addressed.
ROM (read-only memory) generally has the chip of a plurality of mask-programmables and selects (CS) input end.What this means that the buyer can stipulate that each chip selects the input end correspondence is " 0 " or " 1 ".When the appropriate combination of " 1 " and " 0 " being added to chip selection input end, just can select specific ROM (read-only memory).The high address line of address bus is used for each independent memory device is addressed, for example line A24 to A20.Selection input end by suitable selection chip, and they are linked the high address line, independent memory device is addressed, so that be added to particular address on the address bus for microprocessor, have one and only can have memory device selected and can address, these all are known for the professional and technical personnel.
In prior art system, all be usually always to whole memory device power supplies.According to the present invention, there are several adoptable schemes to be used for selectively to 20 power supplies of independent memory device.A kind of scheme is each switch 30 all to be resembled chip handle selecting.Each switch 30 selects input end to be connected on the high address line with the chip of each above-mentioned memory device.In order to select specific memory device 20, select suitable chip combination to be added on this device like this, that switch 30 that this device is connected to power supply just can have been powered.
Another embodiment considers to use 4 to 16 bit line decoders 40, and for example the MC14514B of Motorola removes selector switch 30 and memory device 20.This code translator receives 4 scale-of-two inputs, and produces high output level on 1 that imports in 16 output terminals.In the present embodiment, 4 inputs that the high address line is a code translator 40 that come from microprocessor.Each root in 16 output lines of code translator 40 all connects respectively and controls an independent switch 30.By suitable coding being added to 4 input ends of code translator 40, select a specific switch 30.For example, if binary address 1101 is added to the input end of code translator 40, just memory device 20-13 is powered.
In many systems, all can use storage system of the present invention.A kind of such system shown in Fig. 3.In Fig. 3, aircraft guidance system 42 provides the longitude station of representing aircraft respectively and the signal of Position Latitude.Location finding logical circuit with 44 logical block box indicatings in Fig. 3 receives these signals.Be to understand the location finding logical circuit in detail in 06/560073 the patented claim of awaiting the reply in front as, the sequence number that submit of reference file include in Dec 9 nineteen eighty-three.In this system, terrain data is stored in the storage system by longitude and latitude.In general, the location finding logical circuit is compared at that time longitude data and the predetermined longitude zone in storer individually, and definite aircraft longitude zone at place at that time.The location finding logical circuit is then compared latitude data and the latitude zone be scheduled to, and definite aircraft latitude zone at place at that time.So corresponding aircraft terrain data of position has at that time also just been determined.Then expression and aircraft at that time the signal of the corresponding terrain data in position be sent to storage system 10.According to novel imagination according to the present invention, only select and power to one with the corresponding memory device 20 of position of aircraft at that time.
Therefore can obviously find out, disclosed herein is a kind of storage arrangement that is used for the uniqueness of aircraft warning and early warning system.Storage arrangement and the method for handling terrain data in the map mode go for the common PRACTICE OF DESIGN and the manufacture component of standard.Therefore, though invention describes in conjunction with specific embodiments, can find out obviously that various replacements under the inspiration of above-mentioned explanation, modifications and variations scheme all are conspicuous concerning the professional and technical personnel.Thereby mean within the protection domain of all these are replaced, the modifications and variations scheme also all is included in the claim of enclosing spirit and broad.
