For illuminating the traffic route on airport such as its runway or taxiway.The lamp of airport navigation lamp system must be inspected periodically,
It can be described as Ground lamp, to ensure that they are worked normally.Furthermore it is possible to communicate with each of these lamps so that they can
It is advantageous for use as the signal of pilot.
Some airport navigation lamp systems using unshielded cable be lamp unit power, wherein each lamp unit control to
A few Ground lamp.These existing systems can be upgraded to communicate with lamp unit.But it is possible to independent by these systems
The quantity of the Ground lamp of addressing is fairly limited.
All Ground lamps and all lamp units can be connected to the network of shielding data cable.This will lead to peace
Entirely, reliable and multi-functional system, but need completely new communication system.
Summary of the invention
The present invention is directed to improve airport navigation lamp system, particularly, existing airport navigation lamp system.
The present invention solves the problems, such as this by the method for the feature with claim 1.Specifically, this method includes following
Step: (i) determines the noise level of multiple time slots (S) in the period along AC electric current (I)；(ii) low noise time slot is determined, in institute
Noise level is lower than for example scheduled noise threshold during stating low noise time slot；(iii) low informational message is sent via cable
(Mlow), the low informational message coding relative to the period the low noise time slot it is at least some, particularly sometimes
The timing of gap；And (iv) sends the high informational message of coding-control order during these low noise time slots.
According to second aspect, the present invention solves the problems, such as this by airport navigation lamp system as described above, wherein controlling
Unit is arranged to the step of executing according to the method for the present invention automatically.
It is one advantage of the present invention that many Ground lamps can be controlled.Test has been shown to be able to every available frequency
Processing is more than 500 and most 990 lamps within the time less than 5 seconds.As a result, the machine on relatively large airport can be reequiped
Field navigational lights system.
Another advantage is that error rate is low.Since low noise time slot is used only, channeling is possible, and data pass
Mistake in defeated is unlikely that.
Another advantage is to be not usually required to repeater.Since multiple time slots can be used, maximum frequency can be selected
For lower than such as 30 kHz.Inventor has found that signal decaying is especially high at upper frequency.Due to being able to use lower frequency
Rate decays reasonably low, therefore is not usually required to repeater.
As a result, cable does not need to shield.The present invention is suitable for nearly all existing airport navigation lamp system.
Another advantage of this system is that it is robust.Since low noise is used only in lamp unit and/or control unit
Time channel, according to preferred embodiment, communication electronic equipment can be closed or be set as to close automatically during strong noise time slot
It closes.Therefore, they are not influenced by possible voltage peak.
In the present specification, noise level is especially intended to indicate the amount of undesirable electric current and/or voltage fluctuation.
Noise threshold is especially intended to indicate so that the noise lower than the threshold value will not interfere having been selected for data transmission
Fixed value.It can be with predetermined noise threshold.In other words, noise threshold can be stored in front of determining noise level for example counts
In word memory.Noise threshold selection is high as much as possible, but is low enough to insure that reliable communication.
Alternatively, noise threshold can be implicit.For example, method may include step: time slot needed for (a) determining
Quantity NaSo as to obtain status information from Ground lamp in such as 2 seconds or 5 seconds prefixed time intervals, and (b) select
Select first with lowest noise level.In this case, when noise threshold is higher than the Na with lowest noise level
The noise level of gap and the time slot with (Na+1) lowest noise level.
Phrase " along the period " is intended to indicate that the position of the repeat pattern relative to AC electric current.Instead of phrase " along week
Phrase " along the waveform of AC electric current " or " waveform relative to AC electric current " can be used in phase ".AC electric current can be described asIn other words, AC electric current is the periodic function of time t.Phrase " along the period " refers to
2 π of time mould.
Time slot is intended to indicate that the time interval of the definition in timetable, the i.e. time interval relative to AC electric current.In other words
It says, time slot is that resource can be used during the time interval (in present case with the time interval of determining duration
Under: the transmission capacity of cable) and wherein the time interval periodically occurs (in the current situation: in the period of AC electric current
Or in the half period).
Each lamp unit is connected at least one Ground lamp.For all lamp units, lamp unit is connected
The constant number of Ground lamp be possible, but be not required.
Preferably, the per half period coding of low informational message is less than two bits, such as one bit of per half period.It is so low
Data rate data transmission robust and is not allowed error-prone very much very much.
Preferably, high informational message per half period includes at least 12 bits, such as per half period 17,18 or 19 bits.
The width of time slot is preferably at least 300 microseconds and/or at most 600 microseconds.Each cycle may exist at least 20
Time slot, particularly, at least 30 time slots.Preferably, each cycle, which exists, is less than 60 time slots, particularly, is less than 50 time slots.Often
The amount of bits of a activity low noise time slot is preferably at least 1, but multiple frequency channels are possible and advantageous.It is special
Not, more than two, three or four frequency channels are able to use.Facts proved that more than 9 frequency channels are possible, but
It is not usually required to.
Preferably, cable is unmasked.Certainly, present invention may also apply to shielded cables.But it can also be with non-screen
It covers cable and is used together and be advantageous.
Step (iii) may include sending low noise time slot mask.This is successive bits sequence, wherein each bit clock synchronization
Whether gap is low noise and whether activity is encoded.Timeslot number that can in different ways to low noise time slot, but this
It is a kind of very effective method for doing this part thing.It should be noted that also can be by encoding inactive or strong noise time slot example
As those either low noise but it is not used or not be low noise time slot, come realize coding low noise time slot.This
In the case of, communication occurs over just unmarked in those of inactive or strong noise time slot.
Low noise time slot for sending high informational message is known as active time slot.All low noise time slots are all active time slots
It is possible, but is not required.And if not all low noise time slot be all for the communication with lamp unit it is required,
Least noisy time slot is advantageous as active time slot.
According to preferred embodiment, the bit value of each time slot and each frequency channels is frequency coding or phase code.Such as
Fruit bit value is frequency coding, then bit value 0 is indicated by first frequency, and bit value 1 is by different from first frequency second
Frequency representation.If bit value is phase code, bit value 0 indicates that bit value 1 is by relative to frequency by the first phase of frequency
The second phase of the first phase of rate indicates.Particularly, second phase is 180 °.
First channel can be used for scramble time key message, for example, whether lamps and lanterns are operable, inactive or lack
It falls into.Second channel can be used for encoding non-time critical information, for example, the electrical parameter of lamp unit, such as voltage or electric current.It is excellent
Selection of land, the first channel use the frequency with decaying more lower than other channels and/or noise level.
If bit value is frequency coding, preferably in the centre of each time slot, such as pass through control unit and/or lamp
Tool unit samples frequency.Phrase " in the centre of time slot " was especially intended to indicate between the time near the heart in a slot
Every wherein the interval has 1/10th gap length no more than time slot width.
Preferably, frequency is no more than 30 kHz.As noted above, higher frequency can cause largely to decay, because
This needs repeater.
According to preferred embodiment, for each time slot, using at least four, particularly at least six frequency channels.It is true
It proves, for most of airport navigation lamp systems, at least up to ten frequency channels are possible, this causes high data rate.

The strong noise in face) the higher noise level of time slot, then can send coding relative to the period the low noise time slot at least
The new low informational message of some timings.In other words, if necessary and/or favorably, by change activity low noise time slot.
The waveform of AC electric current can be tangent sine wave (phase-cut sine wave) or sine wave, i.e., completely just
String wave, and each period has at least one electric current edge, and particularly, lucky two electric current edges, wherein the timing of time slot is phase
Electric current edge is determined.This timing of time slot is executed by lamp unit and/or control unit.Electric current edge can be along AC
The time point in the period of electric current, the AC electric current can be detected with full accuracy.Therefore, between control unit and lamp unit or two
Timing miss between a lamp unit matches very little.Therefore, it is able to use relatively small time slot.
If the waveform of AC electric current is tangent sine wave, electric current edge is to steeply rise, and work as phase at the end of tangent
Electric current edge when beginning is cut sharply to decline.If the waveform of AC electric current is sine wave, when the first derivative relative to the time has
When its maximum value or minimum value, electric current edge occurs.
As an alternative, the waveform of AC electric current is sine wave.Certainly, cosine wave is equal to sine wave, because of their only phases
Position is different.The timing of time slot can be determined relative to the phase of sine wave.
