2127714 9313984 PCTABS00024 A pilot activated, self-contained runway lighting system to assist in the landing of aircraft, including a lamp (10), battery means for operating the lamp (10) charged by a solar energy battery circuit, and switch means for activating the lamp in response to coded signals generated by a radio transmitter.
Description
O 93/13984 2 12 7 71~ PCI/AU93/00006 PILOT ACIIVATED R~JNWAY LIGHT~G SYSTEM
The present inYention relate~ to a pilot activated lighting system.
BACKGROUND OF THE INVENTIQN
Full runway lighting for smaller airports and private landing strips are expensive to install and main~ain. Wi~ a withdrawal of Government funding for airport lighting there is a need to provide an affordable system that is easily installed and virtually maintenance free. Such a system must also be able to operate wi~out requiri:ng airport personnel.
OBJECTS OF THE ~NTION
It is an object of the present invention to provide solu'dons to the abovementioned problems.
SUM~ARY OF l~IE IN~ON ~`
With this object in view the present inYention ~ a pre~erred aspect may provide a self-contained lighting system in~uding a la~p, a battery means ~or operating said lamp, a solar e~ergy battery charging circuit and switch means for activating said lamp, said ~-switch means being re ponshe to a code or ~odes transmitted by a radio transmitter.
In a preferred embodiment said swntch mean~ is responsive to a first code for aciiva~ng said lamp and a second code ~or d~
ac~va~ang ~aid l~mp. Preferably activation of said lamp is for a ;~
predete~ed 'ame after which said lamp is de-activated. If required said lamp can flash to indicate that said predetermined ~e is near comple~on.
DESC~ION OF PREFERRED EMBODI~NT ;
In order that the invention may be clearly understood and readily put into practical effect, a preferred non-limitatiYe embodiment of a pilot activated lighting system ~ now be wo 93/13984 21 2 7 7 l 4 - 2 - Pcr/Au93/oo~n~
described with reference to the accompanying drawings, in which:-Fig. 1 is a perspec~ve view of a pilot activated lighting system made in accordance with the invention;
Fig. 2 is a block circuit diagram shown the pilot activated ligh~dng system made in accordance with the invention;
Fig. 3 is a circuit d;.agram of the RF receiving ~ection of the system shown in Fig. 2;
Fig. 4 is a circuit diagram of the counter section of the system shown in Fig. 2;
Fig. 5 i9 a circuit diagram of the fla~her section of the system shown in Fig. 2; and Fig. 6 is the crystal osci~ator sec~on for the RF recei~ng section shown in Fig. 3.
In Figs. 1 and 2 there is shown a pilot activated ligh~dng system made in accordance with the inven'don. The system is self-contained ant is not dependent on fur~e~ modules for its opera'don.
Each system conhins a lamp lO, a battery or batteries 12, solar panels 14 and a charg control circuit 16. The system is in~o~orated in a housing ll which is placed beside the runway in an appropriate posi'don. Housing ll enclose~ battery 12 and charge con~ol circuit 16. Housing ll is preferably made from a W ~tabiL~sed, va~um formed pla~tics m~terial which is very dura~le. If desired housing ll can be designed to collapse if ~truck by an aircraft. Lamp lO is typically a 10 watt quartz hal~en ~obe whi~h has a light output equivalent to a 30 watt tungsten globe. A plurality of such systems will provide suffic:ient ligh~ng to enable a pilot to land a plane. If reguired one system can be used t~ light a windsock or any other device.
To con~ol lamp 10 circui~y is provided to activate lamp 10.
3û The circuitrsr includes an antenna 18 which is coupled to a VHF
receiver detector 20. Detector 20 receives VHF signals from the ~o 93/13984 - 3 - 2 1 ~ 7 7 1 ~ PCI~/AU93/00006 .
pilot's VHF transmitter (not shown). Each transmission sensed by detector 20 is kansformed to a pulse which is coupled to a four pulse counter 22 and a first timer 24. Timer 24 reseb counter 22 15 seconds after first being activated. A latch 26 u coupled to counter 22 and will be turned on after receiving three pulses from counter 22.
Latch 26 will turn on lamp 10 through switch/relay 28 and a second timer 30. Second timer 30 will turn off the lamp after a thirty m~nute countdown. A third timer 32 is provided which controls a flasher unit 34 to cause blinking of lamp 10. The third timer will turn on 0 after 20 minutes to indicate that only 10 minutes remains for the lighting to remain activated. The times for each timer and the numbers of pulses received by counter 22 can be varied depending on particular reguirements. A light-sensitive switch 36 can also be provided to ensure the lighting system is not turned ~n during daylight hs which could dr~lin battery 12.
Figs. 3 to 6 sh~w circuit ~iagrams which enable the blo~k diaglam of Fig. 2 to be realised. The circuit components shown in Figs. 3 to 6 have been referenced to Fig. 2 where applicable. In this preferred embodiment ~e discrete components can be su~tuted by other circuitry and, if required, could be substantially replaced by microprocessor circuitry. Antenna 18 feeds into IC7 which is a I~
narrowband receiver circuit. The audio frequency output from IC7 is ~ltered by an operational amplifier IC8 to provide a trigger pulse TRIG, using relay RELl for each pilot transrnission at the selected f~e~uency on his VHF transmitter. The pilot depresses his call button three times within 15-seconds to supply ~e code for activating lamp 10. The trigger pulse TRIG is fed to IC1, a quad ty~e D flip-flip.
The four flip-flops in ICl are used to form the four pulse counter 22. When the first trigger-pulse TRIG is received by ICl a fifteen (15) oecond tirner IQ is initialised. After fifteen seconds tirner wo 93/13984 212 7 71~1 Pcr/Aug3/o~
IC2 reset~ counter ICl to allow the sequence to start again. If three trigger pul~es TRIG are received in the fifteen second duration of timer IC2 then an output is fed from pin 10 of ICl to latch IC3. Any reset~ng of counter ICl will not affect latch IC3. Latch IC3 turn~ on S transistor Q3 to activate a relay REL2 which controls lamp 10. The output from pin 10 of ICl is also fed to timer IC4 and to timer IC5.
Tima IC4 provides a thirty minute countdown whilst IC5 provides a twenty rninute countdown.
At the completion of the twenty minute countdown ICS
sends an output to transistor Q4 to turn on timer IC6. Timer IC6 provides a pulsed output to turn on and off the relay REL2 controlling lamp 10. Lamp 10 w~ flash continuously as a warning that the thirty minute time limit is shortly to expire and to reduce the load on battay 12. -lS At the of the thirt~r minute countdown the output (pin 8) of IC4 will reset htch IC3. Transistor Q3 will turn off w}dch r~leases the relay REL2 and extinguishes lamp 10.
If the pilot depresæs his call button a fur~er three ~times wliilst the thirty minute is o~urrir~ then latch IC3 and timers IC4, IC5 will be reset providing a fresh thir~r minute countdown. If four pulses are received by counter ICl then the output from pin 15 will reset latch IC3 and ex'dngu~sh lamp 10.
Thus, three depressions of the call button in fifteen seconds will turn on the lamp for thirty minutes whilst four depressions will turn off the lamp mmediately rather than wait for ~e thirty minute timeout.
The ability to turn off lamp 10 results in a more flexible system and does not drain battery 12 to the same extent as the ~irty minute timeout. If required a switch (not shown) can be placed between contacts SW1, SW2 (Fig. 4) to provide a manual override of the ~;~
system.

In practice battery or batteries 12 are typically two 6V 10 amp~our batteries in parallel which draws 1.6 amps per hour. The VHF receiver deteetor 20 draws less than 15mA allowing for 12 hours of illurmination. In the preferred embodiment, the detector 20 draws ~ -as lit~le as 8mA. :

Ea~h system is activated independen'dy and by the same V~ signals. If any systen~ fails, or fails to operate, the rer g systems will not be affected. The system requires very little maintenance. Discharge of batteries 12 is replaced via a 450 m.a. solar voltaic array averaging 3 a/h replenishment on any given day.
