A flashlight control system for an airport aerodrome applied to the present invention and a control method thereof are configured as shown in FIGS. 1 to 8.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted.

In addition, terms to be described later are terms set in consideration of functions in the present invention, and since these may vary according to the intention or custom of the producer, the definition should be made based on the contents throughout the present specification.

In addition, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of description, so the present invention is not necessarily limited to those shown in the drawings.

First, the present invention relates to a flash lamp control system for an airport aerodrome in which the master timer 100 and the flash lamp power supply unit (PSU) 200 have a period of an AC frequency synchronized with each other without modulating the frequency. It has the following technical configuration.

That is, the present invention supplies power to the power supply by receiving power from the outside, supplies control signals of on, off and brightness levels to the power supply, receives the operation status signal of the flash lamp to display the flash lamp status, and displays the flash lamp status in the control room. A master timer 100 that controls the flash lamp according to the flash lamp control command and transmits the flash lamp status to the control room is provided.

In particular, the Master Timer (100) is a remote control station (e.g., CCR room or tower) or the master timer's own operation device (e.g., Key Pad) through the output luminous intensity of a series of flashlights installed on the runway (e.g. : Controls low light intensity, medium light intensity, high light intensity) and transmits a control command trigger signal to start flashing of the flashlight to the power supply of the flashlight. And it can monitor the operation status of the flashlight power supply and transmit it to the remote control station. The master timer can be operated by variably determining the number of flashlights. The trigger signal transmission of the master timer is not transmitted to an individual power supply unit, but provides convenience in batch transmission using the input power line of the power supply unit.

In addition, the present invention performs a function of continuously flashing the LED modules of the light emitting unit sequentially from the outer edge of the runway according to a unique self address by receiving a flash timing and output luminous intensity command signal from the master timer 100, and , Provides a flashlight control system for airport airfields that includes a flashlight power supply unit (PSU) 200 that can be distinguished through a unique address input device attached to the power supply controller and determines the flash sequence of a chain flashlight. do.

At this time, the flash lamp power supply unit (PSU) 200 receives AC220V, AC110V, and 0V from the master timer, and uses AC 220V as power for the PSU and AC 110V for communication. The PSU has its own addressable switch. When the start signal (one cycle short) comes in from the master timer, it plays a role of flashing by driving the LED driving board according to its own address (own cycle). It reads the signals from the LED driving board and the sensors inside the PSU during flashing and transmits its status to the master timer, using SSR.

Meanwhile, the following technical configuration is provided in the master timer 100 applied to the present invention.

That is, the present invention is a master timer operation and display device, and a control panel 110 for displaying an operating state of the flash lamp power supply 200 is provided.

At this time, the control panel 110 is an operation/display device for a master timer. Numbers (1) to (32) of FIG. 4 are LED numbers indicating the operation status of the flash lamp power supply unit (PSU) 200. If PSU 1 is operating normally, LED 1 is on. ● The indicator at the bottom of the main side is an operation status indicator. LED displays various statuses such as SFL RUN (flash light is activated), SFL WARN (warning), and SFL ALARM (alarm). The central LCD (square) and arrow keys function to determine the number of PSUs and set the setting menu for operation. The circular switch at the bottom right is a switch for operating the master timer. REM is a remote operation and operates by receiving an operation instruction from a remote control station. From OFF, LO ME HI is a switch to operate from the master timer, not from the remote. When OFF, the flashlight is turned off, when LO is the low end flash, when ME is the stop flash, and when HI starts the high end flash operation. (Currently the picture is set on the low end flash.)

In addition, in the present invention, the SSR1 of the phase control module is always ON so that most of the current flows through SSR1 before a short circuit, and SSR1 is turned off and SSR2 is turned on in order to short-circuit 110V and 0V, so that the circuit is short-circuited. It is equipped.

In addition, the present invention receives AC 220V power to generate AC110V, and the AC 110V is provided with a transformer 130 used for communication.

In addition, the present invention is provided with a phase control module 140 that serves to receive a signal sent from the master timer control board and send it to the flashlight power supply.

At this time, the method of sending the signal is as follows. SSR1 of the phase control module is always ON, so that most of the current before short circuit flows through SSR1. In order to short-circuit 110V and 0V, SSR1 is turned off and SSR2 is turned on, so the circuit is short-circuited. At this time, since 110V and 0V are short-circuited through the circuit protection resistor, current flows and the circuit is safely shorted. The master timer shorts the voltage in units of one cycle and transmits a command.

In addition, the present invention provides a flashlight control system for an airport aerodrome including a CT (current transformer) 150 that serves to detect the current of an AC110V line.

At this time, the current flowing through AC110V of the CT (current transformer) 150 is when the SSR of the PSU shorted AC110V with 0V, and this is a method for the PSU to send a normal signal.

On the other hand, the flash lamp power supply device (PSU: power supply unit) 200 applied to the present invention is provided with the following technical configuration.

That is, the present invention is a device for sending a signal from a flashlight power supply unit (PSU) 200 to the master timer 100, and a solid state that generates a current by shorting AC110V 0V by receiving a signal from the PSU control board. A solid state relay (SSR) 210 is provided.

At this time, since the solid state relay (SSR) 210 generates a current in a period corresponding to its address, the master timer reads the current through the CT (current transformer) 150 and determines the corresponding address. I can.

In addition, the present invention is a board for controlling a flash lamp power supply unit (PSU) 200, and a control board 220 for analyzing a signal of a master timer by reading the phase of AC110V is provided.

At this time, the above analysis is to calculate the time when AC110V is short-circuited. Time is calculated using a timer interrupt, and the period is determined by calculating the time. When the start command is transmitted from the master timer, it starts flashing in its own cycle and turns on the LED driving board to flash it. In addition, it monitors the LED driving board, monitors the PSU status, and transmits it to the master timer.

And the present invention is provided with an LED driving board 230 for controlling the flash lamp 240.

In addition, the present invention provides a flashlight control system for an airport airport including a flashlight 240 that uses a long lifespan and low power as an LED light-emitting unit, flashes with power supplied from a power supply, and flashes at high, medium, and low brightness. .

On the other hand, the present invention can be variously modified and take various forms in applying the above-described components.

And it should be understood that the present invention is not limited to the particular form mentioned in the detailed description above, but rather, including all modifications and equivalents and substitutes within the spirit and scope of the present invention as defined by the appended claims. It should be understood as.

The operational effects of the present invention flashlight control system for an airport aerodrome and the control method configured as described above will be described as follows.

First, in the present invention, the master timer and the flash lamp power supply unit (PSU) have a period of an AC frequency synchronized with each other without modulating the frequency.

To this end, Figure 1 applied to the present invention is a configuration diagram of a flashlight control system for an airport aerodrome applied to the present invention.

The above method is similar to the existing P.L.C (power line communication) method in that it uses an AC voltage, but the difference is large in that it is used as it is without modulating the frequency. The master timer 100 shorts 110V and 0V of the transformer 130 through the phase control module 140 of FIG. 1.

2 is a detailed circuit diagram of the phase control module applied to the present invention, and a method of shorting 110V and 0V of the transformer 130 through the phase control module 140 is as follows. That is, the phase control module 140 is composed of two SSRs (SSR1, SSR2) and two resistors as shown in FIG. 2.

Therefore, the control board 120 of the master timer 100 always turns on the SSR1 of the phase control module 140 so that most of the current before the short circuit flows through the SSR1. In order to short-circuit 110V and 0V, SSR1 is turned off and SSR2 is turned on, so the circuit is short-circuited. At this time, since 110V and 0V are short-circuited through the circuit protection resistor, current flows and the circuit is safely shorted.

3 is a detailed circuit diagram showing SSR1 of the present invention flash lamp power supply unit (PSU).

That is, the flash lamp power supply unit (PSU: power supply unit) 200 can monitor/detect the state of the LED module, and the current flowing through the circuit when the flash is flashed through the current sensor in the LED driving board 230 is controlled by the control board ( 220) can be detected and the LED is open or short-circuited. In addition, it monitors whether or not the door is opened through a flash lamp power supply unit (PSU) 200 and a door sensor installed in the LED light emitting unit. If the door is opened, both the input power (AC220V) of the flashlight power supply unit (PSU) 200 and the input power (DC48V) of the LED module are cut off.

At this time, when there is no abnormality in the LED module and the power supply unit, the flash lamp power supply unit (PSU) 200 generates a current by shorting 110V and 0V at a period corresponding to its address. The method is as follows.

That is, when SSR1 of FIG. 3 is turned on in the control board 220 of the flash lamp power supply unit (PSU) 200, 110V and 0V are short-circuited through the resistor, so that current flows through the circuit.

4 is a block diagram showing the control panel 110 applied to the present invention.

That is, the control panel 110 is an operation/display device of the master timer, and numbers (1) to (32) are LED numbers indicating the operation status of the flash lamp power supply unit (PSU) 200. If PSU 1 operates normally, LED 1 lights up. ● The indicator is the operation status indicator. LED displays various statuses such as SFL RUN (flash light is activated), SFL WARN (warning), and SFL ALARM (alarm). The central LCD (square) and arrow keys function to determine the number of PSUs and set the setting menu for operation. The circular switch at the bottom right is a switch for operating the master timer. REM is a remote operation and operates by receiving an operation instruction from a remote control station. From OFF, LO ME HI is a switch to operate from the master timer, not from the remote. When OFF, the flashlight is turned off, when the low-stage flash is in LO, the stop flash is in the ME, and the high-stage flash is started in HI (Fig. 4 is set for the low-stage flash).

If, when the LED of the LED module is shorted by more than 25%, or when the circuit is opened, and when a problem occurs in the power supply and does not generate a signal, the master timer 100 calculates the corresponding period in which the signal is not received, Recognizes the number of the faulty flashlight power supply unit (PSU) 200, displays its status on the LED of the control panel 110, and transmits the status of the flashlight to the upper server through the remote contact.

5 is a waveform graph showing a communication method of a flashlight applied to the present invention, showing the start of flashing at intervals of one cycle.

That is, the master timer 100 transmits a command by shorting the voltage in units of one cycle, and the flash lamp power supply unit (PSU) 200 calculates the time when the voltage was short-circuited using a timer interrupt. The command is recognized in the calculated cycle, and if one cycle is shorted, all the flashlight power supply units (PSUs) 200 from the next cycle flash a chain according to their address, and at intervals of one cycle. Start flashing.

At this time, the red curve in the flashlight communication method shows the phase of AC110V. The part represented by a straight line in one cycle is a waveform drawn when AC110V is short-circuited by the master timer 100 for one cycle time. When one cycle is shorted, the first flash lamp power supply unit (PSU) 200 starts flashing in the next cycle, and the second flashes in the next cycle, followed by a series of flashes. At the 7th cycle, the sixth flash light power supply unit (PSU) 200 flashes, and at the same time, the first flashlight power supply unit (PSU) 200 starts detection.

6 is a graph showing a design of a flashlight communication applied to the present invention.

That is, when there is no abnormality in the power supply unit, the flash lamp power supply unit (PSU) 200 generates a current from the 7th cycle and sends a signal. Starting from No. 1, signals are sent at intervals of three cycles. At this time, the master timer 100 senses the current flowing through the circuit through the CT (current transformer) 150, and the flash lamp power supply unit (PSU) of the cycle through which the current flows. : Power supply unit) 200 is to be able to know that it is operating normally.

At this time, the period is one cycle of the sine wave frequency, and 16.6666ms in the case of 60Hz and 20ms in the case of 60Hz are one cycle. The expression in FIG. 6 represents that 30 cycles have passed for 0.5 seconds.

And the master timer indicates the short circuit in the 1st cycle.

In addition, the flash represents a PSU flash once every two cycles, two PSU flashes every three cycles, and then flashes sequentially.

And the PSU flashes well for monitoring/detection, and if there is no problem in the power supply, PSU 1 shorts the SSR 210 at the 7th cycle to create a current and sends a signal to the master timer 100, and then 2 at the 10th cycle. It expresses that PSU is sent and then the signal is sent every 3 cycles.

7 is an explanatory diagram showing a command of a flashlight applied to the present invention.

That is, the master timer 100 can control a variety of flash light power supply units (PSUs) 200 according to the terrain and conditions of the airport, and it is possible to control up to a total of 32, and install flash lights for the first time. By entering and setting the number of flashlights 240 to be used at the airport in the menu of the master timer 100 and the control panel 110, the power supply unit (PSU) 200 is You can monitor and manage the status.

At this time, the master timer 100 transmits a start command once every 0.5 seconds, and repeats and transmits the command from start 1 to start 4 to maintain the flash, and when controlling the brightness or stopping the flash, Send the command together.

This will be described in more detail as follows.

That is, if it is assumed that flashing is performed using a commercial power supply of 60 Hz and 20 flash lamp power supply units (PSUs) 200 are used, 0.5 seconds has a total of 30 cycles.

At this time, if the master timer 100 short-circuits the first cycle, the flash lamp power supply unit (PSU) 200 flashes from its own number from the second cycle, and sequentially flashes until the 30th cycle. It will flash (since there are 20 PSUs, it will flash until cycle 21 and no flash until 22-30).

Therefore, at the time of 30 cycles, 0.5 seconds passed, and all flashlight power supply units (PSUs) 200 finished flashing once at a time. Then, the master timer 100 short-circuits two cycles to notify the flash start signal again. When one cycle is shorted, the flash lamp power supply unit (PSU) 200 starts a chain flash once again from the next cycle. It is done. Thus, after 0.5 seconds, all the flashlight power supply units (PSUs) 200 flash a chain twice in one second.

On the other hand, Figure 8 is a flow chart showing a control method of the flashlight control system for an airport aerodrome applied to the present invention.

That is, the present invention is a control method of a flash lamp control system for an airport aerodrome in which the master timer 100 and the flash lamp power supply unit (PSU) 200 have a period of an AC frequency synchronized with each other without modulating the frequency. It will be described in more detail below with respect to as follows.

(h) The flash lamp power supply unit (PSU) 200 receives a command and controls the LED driving board to terminate the flash, thereby controlling the flash lamp control system for the airport aerodrome.

At this time, communication between the master timer 100 and the flash lamp power supply unit (PSU) 200 applied to the present invention is performed through an AC voltage.

And since the AC voltage supplied from the transformer of the master timer is connected in parallel to all the flash lamp power supply units (PSU: power supply units) 200, the master timer 100 and all the flash lamp power supply units (PSU: power supply units). 200 has a period of an AC frequency synchronized with each other.

In addition, the master timer 100 transmits a command by shorting the voltage in units of one cycle, and the flash lamp power supply unit (PSU) 200 calculates the time when the voltage was short-circuited using a timer interrupt. , Recognize the command at the calculated cycle, and if one cycle is shorted, from the next cycle, all power supply units (PSUs) 200 flash a chain according to their address, and flash at intervals of one cycle. Will start.

And when there is no problem in the power supply unit, the flash lamp power supply unit (PSU) 200 generates a current from the 7th cycle and sends a signal. The signal is sent at intervals of three cycles, starting from 1, and the master timer 100 senses the current flowing through the circuit through the CT (current transformer) 150, and the flash lamp power supply unit (PSU: The power supply unit) 200 is able to know that it is operating normally.
