The image display system comprises a series of images (1) arranged along the track of the vehicle, a discharge lamp (11) for instantaneously illuminating each image, and a plurality of control units (3). The control device comprises a detector (6) for detecting the marking of the vehicle, a counter chain (7) for measuring the time difference as a measure of the speed of the vehicle, and a microprocessor (8) for controlling the illumination means of said at least one image to repeatedly illuminate each individual image of the respective window of the vehicle in response to the detection of the marking, taking into account the speed of the vehicle and the position of the respective window of the vehicle.
Description
The present invention relates to a kind of for example graphical presentation system of the Vehicular occupant displayed image of train and so on that is.
Advised comprising along stock rail and a series of images have been set and work as vehicle by instantaneous each visual display system that illuminates continuously.When Vehicular occupant is watched image, the image blurring that instantaneous illumination is enough to avoid the motion owing to vehicle to cause.The illumination of sequential image when vehicle passes through, the image that can spectators be seen because of the twilight sunset effect of vision is a single width sequential image of television image or film images mode.
Such graphical presentation system is preferably as the device of display ads or literal and pictorial information, for example about the information of the train next stop along the line.Yet because the technical difficulty in implementing, for example in the difficulty of correct instantaneous trigger illumination, above-mentioned suggestion is also successfully unactual to be implemented.
A kind of graphical presentation system is provided according to a first aspect of the invention, and this graphical presentation system comprises along a series of images of the track configurations of vehicle; Instantaneous each visual light fixture that illuminates; At least one control module, when vehicle by the time control at least one images light fixture illuminate image continuously, wherein at least one control module comprises: the detector assembly that detection vehicle arrives; Obtain the device of speed of a motor vehicle value; Control device, described control device is considered car speed and each position of window of vehicle, response flag is surveyed each single image that the light fixture of controlling described at least one images repeats to illuminate each window of vehicle.
The present invention can be thrown light on by using simple control system in accurate timing control.By considering the speed of a motor vehicle and the window's position, can control light fixture and illuminate each image in accurate suitable position, thereby make a series of images be seen as a single width sequential image by each window of these respective window at each image with respect to each image.Because the present invention considers the physical location of each window and controls illumination, so can avoid only by the visual existing problem of existing graphical presentation system of speed illumination that is directly proportional with the speed of a motor vehicle.In this existed system, illuminate image, thereby the observed image of passenger is ambiguous in the vehicle in optional position with respect to any given window.
Preferably dispose detector assembly and come mark on the probe vehicles.Usage flag is done the modification of minimum to vehicle, just can implement this system.Can use single marking to control the illumination of several windows, thereby, mark for each uncomfortable and ugly window.
The speed of a motor vehicle is determined in output by control device.Like this, can usage flag enough determine the speed of a motor vehicle exactly, visual with respect to window in the same position illumination, thus there is not image jitter.
Preferably, light fixture is not installed on inconvenient and the unfavorable car,, otherwise will revises vehicle because it comprises the cutting panel.Display unit can be installed image and light fixture.
Determine that by the output of detector assembly measuring of the speed of a motor vehicle is very simple technically.For example can realize by the time of detecting detector assembly output.A kind of possibility is the time of detecting between two features of mark of the preset distance of being separated by.Two features can be band each or have the length top and the end of the mark of discrete length, for example top of bar code and end.Another kind of alternative plan is, utilizes the detector of two preset distances of being separated by, and surveys the mistiming between the certification mark same characteristic features in the case.The advantage of this system is and can draws measuring of car speed by the single marking on the vehicle (for example Dai bar) that this transformation to vehicle drops to bottom line.
The device of control light fixture preferably includes a microprocessor, and this microprocessor working procedure calculates the illumination timing of each image.Microprocessor makes enough accurately, and timing controlled is achieved.
Wish that control module considers that the position of image controls the light fixture of a plurality of images.This can reduce the cost of system, because avoided each image that one independent control module is all arranged.Even it is irregular to work as image spacing, this considers that impossible by existed system of the speed illumination image that is directly proportional with the speed of a motor vehicle the position of image also can accurately obtain to throw light on regularly.
Preferably, in described control module, exist or do not exist each position of first bit pattern of window to represent each position of window with the position that is illustrated in the predetermined space of being separated by, there is or do not exist described each position of image of each bit representation of second bit pattern of image with the position that is illustrated in the predetermined space of being separated by, control the illumination of each image during the unanimity of the position of described control module by second bit pattern that exists with the incompatible timing that draws each image of illumination in real time of speed relative displacement first bit pattern that is directly proportional with the resultant speed of a motor vehicle and second hyte and when each image of expression and first bit pattern of representing the window's position.For example, control module is shifted to described first bit pattern by shift register, use second bit pattern that the bit location of shift register is transformed to described a plurality of image, control the illumination of this image at the second bit location place carry-out bit that makes up the shift register of presentation image existence.This is to obtain illumination a kind of advanced especially mode regularly, and is reliable because it is simple.
Preferably, mark is encoded to the window's position along vehicle, and control module is decoded to the output of detector and obtained the window's position and use the window's position that is obtained to derive illumination regularly.Such use of coding window position has and does well out of to calculate suitable illumination regularly, thereby improves timing controlled.Because being the position, suitable timing removes the speed of a motor vehicle, so by the window's position of encoding compute illumination timing easily.In addition, can adapt to the different windows structure of dissimilar vehicles or can select visual visible window by changing the coded markings system simply.
Mark can be a bar code, and this is very useful, because bar codes technique itself has obtained having simplified native system than good utilisation and its use.
Existing graphical presentation system has been devoted to near-earth illumination as far as possible with respect to the given window of vehicle each image in same position.This is for preventing that the passenger sees that image jitter or drift are necessary in the car.
According to second aspect present invention, a kind of control device of graphical presentation system is provided, this graphical presentation system when vehicle by the time instantaneous illuminating along the sequential image of a series of images of stock rail configuration, wherein control device control light fixture illuminates the position with respect to the image of vehicle for the various piece of the described series image that part was different afterwards.
Second aspect present invention can be seen the different piece of series image by the diverse location of passenger in viewing window.This existed system with the image of illumination same position forms contrast.This can realize many visual effects, because the image that the passenger saw moves.For example, illuminate the image of the first of series image, illuminate the image of the second portion of series image at the opposite side of window in a side of window.This moving with the content of image coordinated.For example, for two people's discussing at the window opposite side impression, the part of the image sequence that shows in window one side is the first image of discussing, and the part of the sequence that shows in window second side is second people's that discusses a image.A lot of other effects can be used this technology.In each part of image sequence, preferably relatively window at same position each image that throws light on, thereby not shake or drift.
According to third aspect present invention, graphical presentation system is provided, this graphical presentation system comprises: along a series of images of the track configurations of vehicle; Instantaneous each visual light fixture that illuminates; Control device, when vehicle illuminates image continuously by time control light fixture, wherein said serial image comprises the interleaved image sequence in a plurality of cycles.
By interleaved different sequences of cycle, control device optionally is set comes one of displayed image sequence, especially only pass through the image of this sequence of illumination.Thereby, show inhomogeneous image as infructescence, visual type shown in then system can change under the situation that needn't actually replace image according to time of one day.Make system very general like this.
In addition, can use interlaced sequences that sub-threshold image sequence is inserted chief series or produces special-effect by suitable selection image sequence, and, if desired, the control light fixture.
Fourth aspect present invention relates to the capacitive discharge circuits of flashlamp of other system of graphical presentation system of the present invention or the instantaneous bright illumination of needs.In such graphical presentation system, must in the enough short time, illuminate image, to prevent when the illumination causing fuzzy by the relative motion of image.For example, the expectation train is 3mm with the typical rate motion of 30m/s with restriction train and visual relative motion, and illumination period is necessary for 0.1ms.It is known that the flashlamp that is used in for example gas-discharge lamp and so in the capacitive discharge circuits provides instantaneous illumination in other application.Yet known capacitive discharge circuits is very expensive and volume is big, and impracticable to this class graphical presentation system.This is because require illumination instantaneous and enough bright, makes beholder's eyes feel that the image of seeing has enough light summations.
The instantaneous cycle of illumination that it should be noted that the 0.1ms order of magnitude has formed very big contrast with comparing at the TV of longer ratio visible each frame image in the time or film.Therefore must in the discharging capacitor of capacitive discharge circuits, store big energy and realize enough bright flash of light.Yet this requires incompatible with the discharge that must not produce big charging current fast to the capacitor charging.For example, with the typical window of the typical train speed of 30m/s and 2mm at interval, given flashlamp needs the speed flicker with 15Hz.Yet, being charged to enough levels so apace with known electric capacitive discharge circuit and will producing big charging current, this needs bigger and somewhat expensive element to bear electric current and increases power requirement.In other words, known electric capacitive discharge circuit can not satisfy following requirement: enough fast recharging produces bright enough flash of light, and do not produce overcharge current.
According to a forth aspect of the invention, provide a kind of capacitive discharge circuits of flashlamp, this capacitive discharge circuits comprises: at least one discharging capacitor is used for stored charge; A flashlamp; Trigger circuit are provided with these trigger circuit and trigger at least one capacitor discharge by flashlamp; A charging circuit that is used at least one discharging capacitor is given at least one discharging capacitor charging by the inductor of connecting with at least one discharging capacitor.
In charging circuit, use inductance to solve following problem: to revise known electric capacitive discharge circuit, under the situation that does not produce overcharge current, be charged to enough levels.This is because the RC charge characteristic of known capacitor discharge circuit produces the initial high electric current that causes because of RC index of speciality shape.On the contrary, the present invention uses the LC charge characteristic, and this permission has the very fast duration of charging for given maximum charging current, because the start-up portion that is shaped as sine wave of LC charge characteristic.Owing to come current limliting with the inductance of inductor rather than with resistance element, so the present invention also has higher energy efficiency.
Another advantage of the present invention is that making inductor is the fluorescent tube choke inductor.In many capacitive discharge circuits, the cost of enough big inductor is too high, but recognizes, the operating characteristic of the flashlamp of graphical presentation system allows to use cheaply and the fluorescent tube chokes loop type inductor that obtains easily.
Another advantage of inductor is the energy feeding of inductor can be arrived at least one discharging capacitor, thereby increase operating voltage.This is for the electric capacity of the desired discharging capacitor of given energy output the minimizing.For example, this can be realized by charging circuit, charging circuit comprises at least one holding capacitor, the electric capacity of described holding capacitor is bigger than the electric capacity of described at least one discharging capacitor, and the assembled in series of described holding capacitor and described at least one discharging capacitor and described inductor is in parallel.
Preferably, charging circuit comprises a switch, and this switch disconnects at least one discharging capacitor and charging circuit during at least one discharging capacitor discharge, and for example, the trigger pip that trigger circuit are provided adds to switch.This can be avoided making at interdischarge interval the current fed flashlamp of charging circuit, and this does not wish to take place, because it can make the dutycycle of power supply influence the output of flashlamp, and makes lamp enter the operator scheme harmful to lamp.
Preferably, by photo-coupler trigger pip is supplied with switch, photo-coupler adopts the light triac.This has advantage: only the zero crossing at power cycle is restarted switch, does not need resistor in charging circuit, thereby improves energy efficiency.
Capacitive discharge circuits can comprise more than one flashlamp.In the case, each flashlamp preferably has independent discharging capacitor and independent trigger circuit, but this is not necessary.
According to fifth aspect present invention, provide a kind of will show visual mounted thereto, for the display unit that the instantaneous graphical presentation system that illuminates image uses, wherein display comprises: the instantaneous light fixture that illuminates image of setting; Shutter during the illumination that control is provided by light fixture.
Can open shutter start the illumination and/or closed shutter come lighting-off.This has superiority, because many kinds of lamps, gas discharge element for example all is difficult to light fast or extinguish by only controlling power supply, so just is difficult to limit effectively the illumination duration.If the illumination level of light fixture has rise time or fall time, then can use shutter between small part rising and/or decrement phase, cutting off illumination, in the more senior illumination that an advantage is provided.
Any aspect of the present invention or all aspects can be made up.

In order to give for example passenger's displayed image of train and so on, be provided with this graphical presentation system.Figure 1 illustrates the part of display system, described near near the element that (for example, railroad track) installed the vehicles.This part comprises that each all is installed in a plurality of visual 1 in the display unit 2, and display unit 2 has instantaneous each the visual light fixture (below will describe in more detail) that illuminates.Control light fixture by control module 3, control module 3 is connected with display unit 2 by control corresponding line 4.
The image 1 that can comprise any amount by the part of control module 3 controls.Although for the sake of clarity in image 1, only show 4 images,, for quantity that reduces control module and the cost that reduces control module, satisfactory quantity is bigger, is generally 24.Graphical presentation system can comprise a plurality of parts in succession of single part shown in Figure 1 or long period displayed image.
When watching continuously, all images 1 have formed a freeze-frame or change picture series together.Change to produce motion in the image of being watched, for example, the image shown in Fig. 1 resembles and moves the jump ball (bouncing ball), and perhaps changing is color change or other visual effect.Image 1 can display ads or useful literal or picture information, for example about the information of the vehicle next stop.
Preferably, in the predetermined vertical position of image relatively, image 1 comprises at least one horizontal line (not shown), on the main picture and/or the continuous row that under main picture, moves better.Beholder's eyes can be differentiated these row, and these row can be used as compensation because of the installation site of vehicle or the guide of shaking the sequential image perpendicular displacement that causes of vehicle.These row are sightless for normal illumination, and differentiate these row by independent UV-lamp.
Be installed at the height of vehicle window on the wall of tunnel for example or excavation, although can use the display unit that need not rely on stilt in the place that does not have suitable installation surface with display unit 2 walls as shown in Figure 1.Usually need be along stock rail around barrier (for example recess in the tunnel) static image 1.In the case, the interval between the image 1 can increase, and this will produce minimum interference to the image of watching and change the frame frequency of visual 1 sequence at this point.
Figure 2 illustrates the circuit of information display system, in the figure, the with dashed lines frame schematically shows the various unit in the display unit 2 and the position of control module 3.
Control module comprises the infra-red laser diode 5 as electromagnetic radiation source, and the light of these infra-red laser diode 5 emissions is mapped on the vehicle that passes through.Control module further comprises the detector 6 that adopts the infrared remote receiver match, is used to detect any radiation of the diode 5 of vehicle reflection.At the precalculated position height detector 6 and mark are fixed on the vehicle.Use infrared radiation for example to reduce the false triggering chance that causes by the interior lights illumination and avoid radiation to be visible light.A kind of improving one's methods is to use polarization to prevent that spur signal from triggering detector 6.For example only use polarization reflecrtive mark to the polarized radiation sensitivity with detector 6.
Particularly, microprocessor 8 uses the output of detectors 6 to detect vehicle and arrives, thus draw car speed measure and definite vehicle window with respect to the position of mark.
For velocity survey, mark comprises two vertical bars that extend of the zone of reflections of the predetermined space of being separated by.The passage of the bar of process detector produces pulse in the output of detector 6.Mistiming T between two pulses measures as car speed, because T=d/v.The output of detector links to each other with the counter chain 7 of measuring the mistiming between two pulses.Then measured mistiming T is offered microprocessor 8.
Mark is also encoded to the window's position.In order to realize this purpose, mark comprises the bar code that is right after setting after two of band.The output of detector 6 is sent into this as in the bar code chip machine 9 routine, commercially available.When the bar code on the car by the time, the output of the bar code signal modulation detector 6 that produces according to the reflection of the electromagnetic radiation of bar code.Bar code chip machine 9 is decoded with bar code.The bar code of decoding is offered microprocessor 8, and microprocessor 8 uses the bar code of decoding to determine the window's position.Particularly, control module 3 have the corresponding bar code of storage not on the same group the window's position storage list and use the bar code table of decoding to search storage list.These can be stored in the nonvolatile memory of for example EPROM and so on of microprocessor 8.
Can use the measurement of the mark realization car speed of other form.For example, also can use discernible any feature in the output of detector 6, as the top and the end of the horizontal-extending zone of reflections, two that replace using band as two features that obtain mistiming T.Another kind of scheme is, two features are at the top and the end of bar code, and this will have the advantage because of being avoided needing reflection bar and reducing the labelled amount on the vehicle thus.
Other alternative plan is, detector 6 comprises independent probe unit 6a of two of the predetermined distance d of being separated by and 6b, uses in the case by two probe units and detects mistiming measuring as car speed between the single feature.Fig. 3 shows a kind of like this setting of control module, and this is another kind of scheme for the control module 3 of Fig. 1.Fig. 3 shows the independent laser diode 5 for each probe unit 6a and 6b, and signal source is arranged on the relative edge of track for a train so that train interrupt source signal and not reflection.When such setting makes speed can be by single pattern measurement the time, for example an independent bar of the bar code top or the terminal zone of reflections has the advantage that can reduce the labelled amount on the vehicle.
Replace usage flag, can use the speed of some alternate manner measuring vehicle, for example use radar or sound measurement system.
In above-mentioned scheme, the control module mark is encoded to position of window and is obtained position of window by mark.This has the advantage that the different vehicle that makes the different windows structure can be used this system, but this is not necessary.If this graphical presentation system is used for the occasion that vehicle has the window of identical, known location, position of window can be stored in the control module 3, for example is stored in the nonvolatile memory of microprocessor 8.The window's position that this occasion is concrete is stored in the control module 3 when this graphical presentation system of assembling.
Another kind of selectable scheme is to transmit the information of representing the window's position by other device (for example being installed in the transponder on the vehicle) with some.In the case, module can have the receiver of reception information and send information to microprocessor 8.Can use vehicle transponder and display system receiver or T-R between train and control module, to transmit out of Memory, for example select the control information of one of a plurality of horizontally interlaced image series of illumination.Therefore bar code chip machine not necessarily.
The existence and the form of mark are not absolutely necessary.For example, more available alternate manners detect the arrival of trains, for example by when the train front end arrives or some further feature of train side variation that detector is exported when having occurred detect the arrival of train.Can use the detector 6 of other form.For example, detector needn't use infrared radiation.System also needn't rely on radiation reflected.Signal source can be arranged on the opposite side of train and make train interrupt detecting the beam that arrives, if perhaps detector 6 relies on environmental radiation then can omit signal source fully.
Comprise at vehicle the occasion of a plurality of chain meeting carriages independent mark being set on different compartments, thus different compartment response separate marking and control light fixture independently.This can make system use the speed of each compartment independent measurement, and this is just quickening or slow down or there is motion in hitch between the compartment and makes the compartment can carry out timing controlled with slightly different speed more accurately by the occasion of image at for example train.
In Fig. 4, show the program of operation in the microprocessor 8 in a flowchart.
In the output of step S1 microprocessor 8 supervision detectors 6, first feature of check mark, repeating step S1 is till first feature of mark occurs.
When detecting first feature, program proceeds to step S2, in the output of step S2 supervisory controller 6 with the check mark and second feature.If be not checked through second feature of mark, program proceeds to step S3, and the output that monitors counter chain 7 at step S3 microprocessor 8 is to determine whether elapsed time surpasses threshold value after first feature detection.If do not surpass threshold value, program repeating step S2.Making threshold setting is the mistiming T that is slightly larger than greatest hope.If the threshold value that elapsed time surpasses before detecting second feature, then program turns back to step S1, checks first feature of (searching) mark once more.Like this, threshold value can prevent that also the situation of misoperation starting illumination from occurring in the output of detector 6 even spur signal appears at.
If detected second feature before elapsed time surpasses threshold value, then program proceeds to step S4.Microprocessor 8 inputs are from mistiming T the measuring as car speed between two pulses of counter chain in step S4.
At last, at step S5, microprocessor 8 is determined that appropriate illumination are regularly put on control line 4 regularly and at these and is transmitted control signal, thus the image 1 in the illumination respective display unit 2.
Microprocessor 8 obtain the throwing light on timing of each image of being attached thereto, thereby for the different windows of vehicle each image that repeats to throw light on.Can watch this sequence from each of these windows like this.In order to carry out this calculating, microprocessor 8 is considered the position x of each window with respect to mark
w, the speed of a motor vehicle that is specially measurement is removed x
wWhen control module 3 was normally controlled many images at diverse location places, microprocessor 8 was also considered the image 1 position x with respect to detector 6
IIn general, by following equation, can obtain by the mistiming of measuring for position x
wW window lighting position be x
IThe timing t of i image
I, w:
t
i，w＝(x
i+x
w)T/d (1)
By memory image position x exactly
i, can be controlled at timing with respect to each image of the same position illumination sequence of any given window.This can be avoided producing the transversal displacement of the image of being watched from an image to next image of drift with respect to window.Based on same reason, even in the sequence by different control units 3 controls, it is important using consistent the window's position value for all display units 2.Yet, to the window's position relative value x
wRequirement not high, if relatively different windows is watched image in slightly different position, as long as by window still can see these images and for each window arbitrarily at same position each image that throws light on, the window's position relative value just can be accepted.
Replace given relatively window to watch all visual schemes, can control the image or of regularly throwing light in the appropriate section (P14) of the image series of the appropriate section position of different vehicle relatively in same position.To select the memory image position x in the compensation above-mentioned equation of adding (1)
iCan realize this point.This technology can realize many visual effects, because can move the image of being watched by the passenger nearby.For example, can be at the image of the first of window one side illumination image sequence and at the throw light on image of second portion of this sequence of the opposite side of window.This moving with the content of image coordinated.For example, for two people's discussing at the window opposite side impression, the part of the image sequence that shows in window one side is the first image of discussing, and the part of the sequence that shows in window second side is second people's that discusses a image.In each part of image sequence, preferably relatively window at same position each image that throws light on, thereby not shake or drift.
Another kind of selectable scheme is that control is regularly at the gradual change position of relative window illumination sequential image.With the memory image position x in the gradual change compensation above-mentioned equation of adding (1)
iCan realize this point.This technology makes the beholder see the motion video with respect to the window motion itself.
Generally speaking, microprocessor 8 has suitably timing Calculation Method of many processing in step S5.But employed optimization technique is as follows in description embodiment.
The corresponding position of image x of the incompatible expression of hyte with known conduct " train figure "
wEach bit representation of train figure exists or does not exist at the constant predetermined space r position window of being separated by.If train figure is 10100101, represent that then window appears at position x
w=r, 3r, 6r, 8r place.
Similarly, with the corresponding position of image x of the incompatible expression of hyte of known conduct " tunnel figure "
iEach bit representation of tunnel figure is in the existence of the predetermined space r position image 1 of being separated by or do not exist.If tunnel figure is 00101001, then presentation image appears at position x
Wi=3r, 5r, 8r place.
Use train figure and tunnel figure to throw light in real time regularly by two the incompatible acquisitions of hyte that relatively move with the speed that is directly proportional with car speed, be directly proportional with the ratio of predetermined distance d and predetermined space r, thus when respective window with visual 1 mutual when adjacent tunnel figure consistent with the corresponding positions of train figure.Corresponding image throws light on when this consistance occurs.The predetermined displacement timing t that provides by establishing an equation down
sMove tunnel figure along shift register and realize this point:
t
s＝(r/d)T (2)
Tunnel figure transforms to each bit position (bit position) of shift register in corresponding visual 1.Use tunnel figure that the bit of shift register is transformed on the control line 4 for corresponding visual 1.Use resembles 1 bit position that occurs at tunnel figure presentation graphs the position of shift register is as control signal and be connected to the corresponding control line 4 of corresponding image 1.
Therefore, use shift register on control line 4, to produce gating pulse in real time automatically by correct timing.Shift register is the optimal way of realization this point, because it can obtain with the processing power of minimum regularly, does not need calculating and stores all regularly in initial step for all images and window.Because different control lines 4 are parallel to each other and carry the position in the shift register outer, provide control signal simultaneously to different images 1 so can also control.
The size of predetermined space r is the resolution of window figure and tunnel figure.Can select the value of predetermined space r according to the position of display requirement on the car and the graphical presentation system of being discussed.Generally speaking, for fear of the location of restriction display unit 2, the preferred use hanged down predetermined space r.The additional operations that the length that increases the bit pattern that constitutes train figure and tunnel figure is so just arranged, but microprocessor 8 still can easily be handled the bit pattern of such length.
The control signal of microprocessor 8 being exported by the array of driving circuit 12 flows to control signal wire 4, and the array design of this driving circuit 12 becomes the sufficient level that the digital controlled signal level conversion is become to supply with control line 4.
Each display unit 2 all is equipped with a capacitive discharge circuits 10, and this capacitive discharge circuits 10 makes light fixture luminous and shine image 1 in this display unit 2.Describe the structure of capacitive discharge circuits 10 and light fixture below in detail.Each bar of control line 4 all links to each other with the capacitive discharge circuits 10 of an independent display unit 2 and triggers capacitive discharge circuits 10.
Although during being of short duration illumination,, in order to see image 1, the illumination level is height enough.If it is enough strong with respect to surround lighting to throw light on, then graphical presentation system will comprise daylight working under the environment light condition arbitrarily.Therefore, the surround lighting of system for use in carrying is selected sufficiently high illumination intensity.
In order to satisfy these requirements, although can use other gas-discharge lamp or flashlamp, light fixture had better be made up of at least one xenon gaseous discharge lamp 11.Light fixture is made up of machinery and four xenon gaseous discharge lamps 11 that are electrically connected on the printed circuit board (PCB) 16 in the present embodiment.Near printed circuit board (PCB) 16 peripheries, a determining deviation is provided with discharge lamp 11 at interval, makes the light that is produced by discharge lamp 11 pass the back transmission of image 1.
In order to satisfy above-mentioned instantaneous, bright illumination requirement, capacitive discharge circuits 10 designs are as follows.Fig. 7 shows the circuit diagram of capacitive discharge circuits 10.For the sake of clarity, the circuit diagram of Fig. 7 only shows an independent discharge lamp 11, and all circuit components shown in the dot-and-dash line for each discharge lamp 11 that is parallel to each other and among the multiple Fig. 7 that overstates in fact.
Each discharge lamp has two discharge capacities, is specially main discharge capacitor C 3 and impulsive discharge capacitor C 2.Main discharge capacitor C 3 is actually one for making the lamp 11 luminous electrochemical capacitors (be generally 33 to 100 μ F, be preferably 68 μ F) that the discharge main energy sources is provided.Main discharge capacitor C 3 has low internal resistance and main discharge electric capacity is made at interdischarge interval ability high-current pulse.For than faster strengthening the flash of light dynamic perfromance, impulsive discharge capacitor C 2 is the little electric capacity (being preferably 0.1 to 1 μ F) of a non-electrolysis and has low internal resistance and inductance.Discharge capacity C3 and C2 are in parallel with xenon gaseous discharge pipe 11.
Adopt the switch S 1 by bipolar transistor or mosfet transistor realization of transistor version, switch S 1 is connected with inductance L 1.Switch S 1 makes discharge capacity C2, C3 and lamp 11 disconnect with power supply when triggering lamp 11.Therefore, by the control signal of terminal 17 is offered switch S 1 and make switch S 1 conversion when the phase place of the control signal of supplying with controllable silicon TH1 is opposite through the second photo-coupler O2 that is generally conventional transistor-type.During discharge lamp 11 illuminations, can avoid electric current directly to pass through discharge lamp like this from power supply.Avoid the power supply dutycycle that the output of flashlamp is exerted an influence and prevent that flashlamp 11 from entering harmful operator scheme.
In addition, to the bridge rectifier power supply, between positive-negative power line 27 and 28, be connected with storage capacitors C1 by resistance R 1.Owing to the reason current-limiting resistance R1 that discusses below and storage capacitors C1 not necessarily.
The operation of capacitive discharge circuits 10 is described below.
After applying power supply, electric current flows through diode D2, inductor L1 and switch S 1 and gives discharge capacity C2, C3 charging till voltage stops electric current to flow through diode D2.This voltage is in the scope of 270V to 400V under normal condition.This is the stationary state of capacitive discharge circuits 10.
When control signal is supplied with control end 19, trigger discharge lamp 11, the electric charge on discharge capacity C2, the C3 is discharged by lamp 11, produce desired instantaneous illumination period.Certainly, trigger four all flashlamp 11 simultaneously.During this period, control signal disconnects switch S 1, thereby lamp 11 and power supply are disconnected, and the electric current that flows through lamp 11 only is the discharge current from discharge capacity C2, C3.
This differs widely with the charging with conventional capacitive discharge circuits of passing through resistance of RC characteristic.In Fig. 8, also show typical RC charging curve 21.Compare with LC charging curve 20, as can be seen, at the start-up portion of the RC of slope maximum charging curve 21, the duration of charging is longer, and maximum charging current is higher.If by the resistance that reduces in the charging circuit shortened in the duration of charging of RC charging curve 21, then charging current can become higher.Thereby, in charging circuit, use inductor can improve the balance that obtains the rapid charge time and do not produce overcharge current.
In addition, provide inductor L1 to mean resistance limits electric current, rather than limit electric current, so have only less energy consumption by resistance element by inductor L1.
Further, use inductor L1 can make the energy back that is stored among the inductor L1 give discharging capacitor C2 and C3, so that entirely increase the operating voltage of system.For given output energy, this will reduce the size of desired discharging capacitor C2 and C3.Because energy is directly proportional with the capacity of discharging capacitor, and square being directly proportional of energy and voltage, so just can use little a lot of capacitor also thereby save cost greatly like this.
In order to utilize the energy that is stored in the inductor in this way, charging circuit comprises the storage capacitors C1 that is connected across both ends of power, thereby the tandem compound of charging circuit and discharging capacitor C2, discharging capacitor C3 and inductor L1 is in parallel.Reservior capacitor C1 is the big electrolytic condenser (preferably 220 μ Fs) of an electric capacity much larger than discharging capacitor C2 and C3, and on the contrary, if omit reservior capacitor C1, discharging capacitor C2 and C3 just have smaller capacitive.Storage capacitors C1 carries out filtering and the filter peak that is higher than RMS power values dc voltage is provided the DC supply voltage of rectification.
In operation, the energy back that will be stored in during discharge cycles among the inductor L1 is given discharge capacity C2 and C3, have the very fast effect that reclaims of reservior capacitor C1 and discharging capacitor C2, C3 like this, and can also keep higher total voltage at discharging capacitor C2 and C3 two ends.
In this scheme, the current-limiting resistance R1 that connects with AC power supplies is set, prevent at the dash current that powers up with operating period reservior capacitor C1 excessive.Can be at the input end of the not rectification side of rectifier D1 one 100 μ F small capacitor (not shown) in parallel, but this is not necessarily.
Be operated in the high frequency duty of (for example being higher than 15Hz) for flashlamp, reservior capacitor C1 and resistance R 1 preferably are provided.Yet, at lower blink speed, needn't provide reservior capacitor C1, can save cost like this.In the case, photo-coupler O2 is a light triac preferably, connects the light triac and switch S 1 is not worked.Has the advantage of only restarting switch S 1 like this at the zero cross point of power cycle.Thereby soft start is provided and thereby has not needed to improve the current limiting capacitance C1 of energy efficiency.
Can do multiple being amended as follows to capacitive discharge circuits shown in Figure 7 10.
Replace photo-coupler O1 and O2 separately, use an independent photo-coupler (perhaps as transistor circuit or be the light triac) not only trigger flashing lamp 11 but also gauge tap S1.Preferably, single photo-coupler is arranged to, another charging capacitor (not shown) is linked to each other with the grid of controllable silicon TH1, thereby make the control signal that is added on the controllable silicon TH1 produce pulsation.Said another charging capacitor can directly be connected with the control input of switch S 1.In the case, another resistance of series connection the line from this charging capacitor to controllable silicon TH1 is so that provide suitable time constant to pulse.For example, another capacitor and another resistor have the resistance value of capacitance and the 1.5k Ω of 10nF respectively.Another electric capacity is kept discharge when photo-coupler is connected, thereby makes switch S 1 invalid by common mode.In order to charge, said another capacitor is connected with big resistance (150k Ω) between positive power line 27 and negative power line 28, thus with the rectification DC power supply of reservior capacitor C1 filtering by charging for another capacitor by big resistance.Preferably be limited in voltage on another capacitor by for example Zener diode.Send power supply to controllable silicon TH1 with pulse, advantage is to make controllable silicon keep its state.Such modification requires the common port of transformer T1 to link to each other with negative power line 28, and does not link to each other with the negative electrode of flashlamp 11 shown in Figure 7.
The supply voltage of non-filtered, by suitable diode and resistance, can be used as accessory power supply and supply with photo-coupler O1 and O2 (or single photo-coupler, if use single photo-coupler) and/or controllable silicon TH1, thereby, when guaranteeing to break down in circuit, these devices also will never keep locking.
Replace giving each flashlamp 11 that the scheme of resistance R 2, capacitor C4 and transformer T1 is provided respectively, can use public trigger circuit to come trigger flashing lamp 11, provide public resistance R 2 and capacitor C4 to come perhaps for all four flashlamp 11 to corresponding transformer T1 feed.
For the sake of security, big resistance (330k Ω) can with discharging capacitor C2 and C3 be in parallel and in parallel with reservior capacitor C1, makes the electric charge leakage when capacitive discharge circuits 10 disconnects with power supply AC that is stored in these capacitors.
At last, the anode of additional diode links to each other with node between switch S 1 and the inductor L1 and presses, and the negative electrode of additional diode links to each other with positive power line 27.The operation of this diode is only just meaningful when frequency of operation becomes than expection high, in the case cut-off switch before capacitor is full of electricity fully again.In this case, such diode can prevent the damage that switch caused because of overvoltage.This excess energy that also has self-inductance device L1 in future feeds back to the advantage of reservior capacitor C1.
The series of image 1 can comprise the interlaced sequences in a plurality of cycles of image 1.For example, alternately determine two sequences of expression different motion image along this series.Under the control of microprocessor 8, allow selectively one of display sequence.Image shown in changing easily under needn't the situation of actual shift image like this.For example, control variation according to one day time.
Preferably, microprocessor 8 monitors each visual Coefficient of Utilitization, cuts off illumination when Coefficient of Utilitization is lower than threshold value.Select threshold value with the quite low Coefficient of Utilitization that can produce harm or infringement, perhaps select threshold value with the quite low Coefficient of Utilitization that can cause image flicker to the spectators on the vehicle.Generally speaking, threshold value is a general value not, and changes with flash of light and surround lighting level, but common cut-out level is per second kind 16 or 20 illumination.
Can be added to a optional characteristic in the said system and be notice with spectators and be attracted to some devices on the upcoming image sequence.Can make display effect the best like this and can prevent that spectators from missing the initial image of sequence.One of this device may scheme be, the display unit 2 of top described type is fixed on the front of image sequence and demonstrates color or image or noticeable image that pattern is bright.Another kind of possible scheme is in the front of image sequence lamp to be set.Lamp can be colored lamp or flashlamp.Move these lamps mutual vertically so that produce the jet effect.With triggering lamp with similar control system or the better simply control system of only surveying mobile train or mark of above-mentioned display unit 2.In addition, can use sonorific warning device, for example produce the warning device of partials, voice or music.
Make visual 2 deepenings to reduce the visibility of image when not throwing light on.The visual caused image that can see to a certain extent because of the parasitic light reflection of for example vehicle in the time of will reducing even without illumination like this is chaotic.To produce image chaotic for the visibility of little like this summary when vehicle moves with respect to the window of process.The optimal way that makes visual deepening is with substrate 13 and/or cover plate 15 in the material display unit 2 of blackout.In addition, can make image 1 deepening own.When visual 1 deepening, the illumination level that must increase lamp 11 compensates.
Can use the display unit 2 of other form.
Figure 9 illustrates another kind of alternative structure of display unit 2.In this structure, image 1 is fixed in the closed steel plate box.Lamp is arranged on image 1 back and below image 1, will goes out by visual 1 direct projection from the light of lamp 11 at the reverberator 23 of visual 1 back.
Figure 4 illustrates another kind of alternative structure of display unit 2.Image 2 is installed on the first type surface of transparent panel 24.In the shell 25 of the lower limb that is connected to plate 24 lamp 11 is housed, lamp 11 is launched light, enters the edge of plate 24.
A shutter selectively is provided, assists to control the instantaneous illumination of image 1.Such shutter has been shown in Fig. 9 and Figure 10, it lamp 11 and will be from the optical system on the light directive institute installation diagram of lamp between, that is, and reverberator 26 in Fig. 2 display unit 2 or the transparent panel 24 in the display unit 2 of Figure 10.Shutter 26 preferably has the optical element of controlled transmissivity, for example liquid crystal shutter.
In the display unit 2 of Fig. 5 and Fig. 6, shutter is set by cover plate 15 being formed optical element (for example liquid crystal) with controlled transmissivity.Can use the optical shutter or the mechanical shutter of other type.
If lamp is to be difficult to the class lamp lighting fast and/or extinguish by independent control power supply, shutter is set then.For example, in order to make its efficient maximum and power consumption minimum, the gas discharge element of having developed, but it still is difficult to accurately control photoemissive starting and stop.Illumination level has the tangible rise or fall time.Can not cut off the driving voltage of capacitor discharge immediately.This just is difficult to the restriction illumination duration.Use shutter just can avoid these problems.Open shutter and can start light fixture, closed shutter can be closed lamp and/or the light fixture of having connected the front, and the result disconnects light.At least shutter can cut off illumination in during the part of rise time of illuminance or fall time, so that only provide illumination in the highest illuminance.By control signal to control the Kai Heguan of shutter at the accurate timing of illumination.
In addition, display allows the selection of different images to show.For example, several images 1 are printed on the annular cylinder, cylinder can wind the orbit rotation that is limited by roller bearing (roller), thereby selectively image any width of cloth of 1 is placed on the viewing position of front surface of display unit 2, adopts the mode of the scroll (scroller) of the color filter color of using in the stage lighting system, be used to change the lamp front.
Another kind of alternative plan is by showing that the controlled LCD display that can select image 1 constitutes the front surface of display unit 2.This has needing to avoid the actual advantage that changes the image of installing.Preferably, but not necessarily, described LCD display and back illumination combination above.At present the cost of LCD display is too high, but is feasible on this systems technology and cost might drop to receivable level.
Another kind of alternative plan is to use the advertisement poster that illuminates previously.Yet, use back illumination better, reflect less surround lighting and darker because under luminance not, adorn the transparency of lamp behind, especially out of doors than advertisement poster.This means transparency that almost can't see non-luminous behind dress lamp and do not influence the image of being watched.
The substitute is, the image projection that can little behind be equipped with transparency by an optical system is to the surface as the display unit of screen.This also has advantage: can't see image at all and can easily change image when turn-offing illumination.But the optical system of closing the symbol quality requirements is very expensive and be difficult to obtain the image of satisfactory quality.
