The present invention relates to a dual aviation lighting power supply system, and more specifically, one power supply for aviation lighting equipment such as runway lights, runway distance lights, taxiway lights, and taxiway guide lights that provide aircraft movement path information during takeoff and landing at night. This relates to a system that can build a stable, uninterrupted aviation lighting facility during night airfield operation by automatically connecting another circuit through a bridge circuit in the event of a circuit failure.

In general, aviation lighting equipment is a security facility on the ground that helps aircraft navigate by lighting at night or in bad weather, including runway approach lights, approach indicator lights, runway lights, taxiway lights, taxiway guide lights, taxiway center line lights, and aviation lights. There are disabilities, etc.

It is installed and operated in compliance with the regulations (ICAO FAA UFC aviation lighting technology standards).

Aviation lighting facilities operated in accordance with these regulations are divided according to their use functions as follows.

First, approach lighting informs aircraft pilots of the direction of the runway during the day or night and visually guides the aircraft to land safely and accurately on the runway. It includes approach lights, runway threshold lights, approach angle indicators, and runway end lights. It is divided into identification lights and turning lights.

Second, runway lighting indicates the area of the runway with light or color to prevent aircraft from leaving the runway. It is divided into runway lights, runway center line lights, runway end lights, runway end lights, touchdown zone lights, and runway distance lights.

Third, taxiway lighting serves as a type of traffic light and sign on the road. It is a light that allows aircraft to move safely and quickly on the ground when driving on a taxiway. This includes taxiway lights, taxiway center line lights, stop line lights, It is divided into temporary stop position lights, taxiway guidance lights, taxiway intersection lights, and runway boundary lights.

Fifth, location lighting is a light that indicates the location of the airfield to which you are navigating, and there is an airfield lighthouse.

Usually, the runway light power system consists of two groups of runway lights at 60M intervals along both sides of the runway, for example, group 1 runway lights and group 2 runway lights are installed in accordance with IACO 14 and aviation lighting technical standards, respectively. The runway lights (10a, 10b) of each group are individually wired through the first group circuit and the second group circuit extending from each power building, which is the airport's aviation lighting power supply location that manages the overall control of the runway light power system.

As shown in Figures 1 and 2, the aviation lighting power dual system has a power supply failure of aviation lighting equipment (approach lighting series, runway series, taxiway series) that provides information to takeoff and landing aircraft at night and in low visibility situations. It is a system to prepare for situations where pilots are unable to identify aviation lighting equipment. It supplies power through a dual type consisting of two circuits, so even when one circuit fails, it supplies power to the other circuit. , It is a system that can significantly contribute to the uninterrupted operation of aviation lights by continuously operating aviation lighting facilities in accordance with ICAO FAA UFC aviation lighting technology regulations.

For this purpose, the aviation lighting power dual system basically has first group runway lights (10) and second group runway lights (11) installed at regular intervals, for example, at 60M intervals, along both sides of the runway (100). (For example, among a plurality of first group runway lights and second group runway lights installed at regular intervals, neighboring first group runway lights and second group runway lights are installed at intervals of 60M from each other.), At this time, each The first group runway lights (10) and each second group runway lights (11) are connected to two circuits extending from the airport's power building (13), which manages the overall control of the runway light power system, namely the first group circuit (14). ) and a system electrically wired with the second group circuit 15 to receive power supply and operation control.

Here, the power building 13 of the airport is responsible for controlling the runway lights and runway distance lights as well as taxiway lights, taxiway guide lights, runway center line lights, runway threshold lights, and simple approach angle indicator lights. It becomes possible.

Looking at this aviation lighting power dual system in more detail, it is as follows.

The aviation lighting power dual system can operate various aviation lights at the airport such as runway lights, runway distance lights, taxiway lights, taxiway guide lights, etc. with uninterrupted power supply. Below, the runway lights and runway distance lights can be operated with uninterrupted power supply. An embodiment of operation using a power supply method will be described.

A plurality of first group runway lights 10 and second group runway lights 11 are installed at 60M intervals along both sides of the airport runway 100, and at the same time, a plurality of first group runway lights 10 and 2nd group runway lights 11 are installed at 300M intervals along both sides of the airport runway 100. Runway distance lights (12) are installed, and each first group runway light (10), second group runway light (11), and runway distance light (12) extend from each power building (13) of the airport. It is wired through the first group circuit 14 and the second group circuit 15 to receive power supply and operation control.

These first group runway lights (10), second group runway lights (11), and runway distance lights (12) are common cans installed at regular intervals along both sides of the runway (100), that is, common steel holes (16). Includes each.

Here, the common steel hole 16 is in the form of a cylindrical case, which is a type of aviation lighting equipment, and series circuit transformers 17a, 17b, bridge circuit 21, etc. are accommodated therein, and is located on both sides of the runway 100. In addition to being installed in a buried structure, it is possible to form a structure that communicates with a cable installation pipe (not shown) for underground installation of the first group circuit 14 and the second group circuit 15.

In addition, the first group runway lights (10), second group runway lights (11), and runway distance lights (12) are a means of visually providing aircraft movement path information to aircraft pilots, and include the runway light lamp (19) and the runway distance light (12). Includes street light lamp (22).

The runway light lamp 19 and the runway distance light lamp 22 are known LED lamps used for runway lighting, and are supported inside each runway light case 18 and the runway distance light case 20 and are exposed above the ground. It is installed and electrically connected to the series circuit transformer (17a, 17b) to receive power supply and operation control.

For example, the runway light lamp 19 is installed inside the common steel hole 16 belonging to the first group runway lights 10 and the second group runway lights 11, and the first group circuit 14 ) and the second group circuit 15 and the series circuit transformers 17a and 17b respectively wired, and the runway distance light lamp 22 is connected to the common steel hole belonging to the runway distance light 12 ( In addition to being installed inside 16), the series circuit transformers 17a and 17b are respectively wired with the first group circuit 14 and the second group circuit 15, and are wired to the series circuit transformers 17a and 17b at this time. It is electrically connected to the bridge circuit 21.

Here, the installation method of the common steel hole 16, the runway light lamp 19 and the runway distance light lamp 22 as well as the cable laying pipe is the same as the known installation method usually adopted when constructing aviation lighting facilities. Therefore, detailed explanation will be omitted.

In particular, the runway distance light (12) includes a bridge circuit (21) electrically connected to the series circuit transformer (17a, 17b) wired with the first group circuit (14) and the second group circuit (15). do.

The bridge circuit 21 is a type of bridge rectifier and consists of a bridge circuit connecting four diodes. It outputs the same polarity voltage no matter what polarity voltage is input, and is usually used to change alternating current input to direct current output. .

The input side of this bridge circuit 21 is electrically connected to the two series circuit transformers 17a and 17b belonging to the runway distance lights 12, and the output side is electrically connected to the runway distance lights 22.

Therefore, as shown in Figure 3 (A), when a positive voltage is applied to the left side of the diamond and a negative voltage is applied to the right side of the diamond from one series circuit transformer (17a), the current is output from the left upward to the runway distance. After going through the light ramp 22, return from the bottom to the right.

Conversely, as shown in (B) of FIG. 3, when a positive voltage is applied to the right side of the diamond and a negative voltage is applied to the upper side from another series circuit transformer (17b), the current is output from the right side to the top and extends to the runway. After passing the street light ramp (22), return from the bottom to the left.

In this way, by using the operation characteristics of the bridge circuit 21, it is possible to continuously maintain an uninterrupted power supply even when power supply from either of the series circuit transformers 17a and 17b is interrupted.

Here, the bridge circuit 21 may be installed inside the runway light case 18 and the runway distance light case 20, and in some cases, may be installed inside the common steel hole 16.

In addition, the first group runway lights 10, second group runway lights 11, and runway distance lights 12 include series circuit transformers 17a and 17b as a means of raising or lowering the voltage.

The series circuit transformers 17a and 17b serve to supply the power necessary to drive the runway light lamp 19 and the runway distance light lamp 22, and are a power circuit that generates the necessary output power from the input power.

These series circuit transformers (17a, 17b) are installed inside the common steel hole (16), are electrically connected to the bridge circuit (21), and are connected to the first group circuit (14) and the second group circuit (15). are electrically connected to each side.

Here, one series circuit transformer (17a or 17b) is installed in each common steel hole (16) belonging to the first group runway lights (10) and the second group runway lights (11), and the runway distance Two series circuit transformers (17a and 17b) are installed in the common steel hole (16) belonging to the light (12).

In addition, the power building 13 of the aviation lighting power dual system includes two constant current regulators mainly used in the circuit of aviation lighting equipment, for example, a first common constant current regulator 13a and a second common constant current regulator 13b. Includes.

The first common constant current regulator (13a) and the second common constant current regulator (13b) maintain a constant output current when the change in input voltage or load is within a specified range or when the surrounding conditions are within specified conditions. It is a power supply that is maintained properly.

The first common constant current regulator 13a and the second common constant current regulator 13b are installed on the power building 13 side, and the first common constant current regulator 13a and the second common constant current regulator 13b are installed in the power building 13. When installed on the (13) side, the first group circuit 14 and the second group circuit 15 can be extended from the first common constant current regulator (13a) and the second common constant current regulator (13b), respectively. .

As another example, the first common constant current regulator (13a) and the second common constant current regulator (13b) may be installed inside the common steel hole 16, and the first common constant current regulator (13a) is one series circuit. Between the transformer (17a) and the first group circuit (14), the second common constant current regulator (13b) can be electrically connected between another series circuit transformer (17b) and the second group circuit (15). do.

Meanwhile, two circuits are wired from the power building 13 to the first group runway lights 10, the second group runway lights 11, and the runway distance lights 12 of the runway, for example, the first group circuit. (14) and the second group circuit (15) are wired along cable pipes (not shown) buried along both sides of the runway (100) during construction of aviation lighting equipment, and the first group circuit (14) is wired in this way. ) and the second group circuit (15) passes through the inside of each common steel hole (16) belonging to the first group runway lights (10), the second group runway lights (11), and the runway distance lights (12). I do it.

For example, the line forming the first group circuit 14 and the second group circuit 15 includes the first group runway lights 10, the second group runway lights 11, and the runway distance lights 12. Wiring can be done by sequentially passing through each common steel hole 16 included.

In this way, the first group circuit 14 of the first group circuit 14 and the second group circuit 15 passing through the common steel hole 16 is connected to the series circuit transformer 17a (or the first common constant current regulator is connected to the series circuit transformer 17a via), and the second group circuit 15 is connected to the series circuit transformer 17b (or is connected to the series circuit transformer 17b via a second common constant current regulator).

Accordingly, the power provided from the power building 13 is supplied to the series circuit transformers 17a and 17b through the first group circuit 14 and the second group circuit 15, respectively, and the power supplied in this way is It can be provided to the runway light ramp 19 side and the runway distance light lamp 22 side through the bridge circuit 21.

For example, the first group circuit 14 extending from the power building 13 of the airport is connected to one DC circuit transformer 17a belonging to the first group runway lights 10, and the adjacent second group circuit After skipping the runway lights (11), it continues to be connected to one DC circuit transformer (17a) belonging to the next first group runway lights (10) in the sequence, while the airport power source The second group circuit (15) extending from the wing (13) is connected to one DC circuit transformer (17b) belonging to the second group runway lights (11) and across the neighboring first group runway lights (10). After jumping, it continues to be connected to one DC circuit transformer (17b) belonging to the next second group runway light (11) arranged in sequence.

In addition, the first group circuit (14) and the second group circuit (15) between the first group runway lights (10) and the second group runway lights (11) are two direct current circuits belonging to the runway distance lights (12). It continues to be connected to the transformers 17a and 17b, respectively.

Therefore, when controlling the output by the power building 13, power is supplied or cut off to the first group circuit 14 and the second group circuit 15, and each lamp of the runway light and runway distance light is turned on. Alternatively, it can be turned OFF (lights off) to provide aircraft movement route information to pilots during night takeoffs and landings.
