Abstract

PURPOSE:To enable luminous intensity and flashing to be properly controlled according to changes in conditions such as background brightness and environmental conditions by automatically observing those conditions and automatically entering obtained observation data. CONSTITUTION:Data required to calculate a proper luminous intensity is automatically observed by environmental data observation parts 1a to 1n, retrieved by data input parts 2a to 2n, and calculated by an operation processing part 3 to determine a proper luminous intensity. The results are supplied to a control processing part 4 and if the proper luminous intensity has changed, a communication part 5 is informed that the luminous intensity should be switched. And if the switching of luminous intensity poses no problems, a switching enable signal is entered from an operation part 6. Further, proper luminous intensity data is output from a controlled output parts 7a to 7n in a controlled manner. This constitution provides an aeronautical ground light control device which allows luminous intensity and flashing to be properly controlled according to changes in conditions such as background brightness and environmental conditions.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aviation lighting control device for controlling luminosity and blinking of aviation lighting provided at an airport.

[0002]

2. Description of the Related Art Aviation lights are installed at airports to provide continuous and balanced visual information to take-off and landing aircraft, in order to ensure proper visibility under all weather conditions. Light intensity control and blinking control are performed according to the background brightness and environmental conditions.

Such light intensity control and blink control are performed in the background (daytime, twilight, night), visibility (0 to 800 m, 800).
-1600m, 1600-5000m, 5000m or more) and cloud height (300m or less) are combined, and these conditions are manually selected by the controller using pushbutton switches on the lighting operation table installed in the control tower. Is input to the aviation lighting control device.

[0004]

In the conventional aviation lighting control apparatus, for example, the background conditions are only divided into three categories, daytime, twilight, and night, depending on the sunrise and sunset times. In addition, although the background brightness is treated as constant in each of the three time zones, the actual background brightness of the lamp may vary depending on the weather conditions and the like, and thus may not always be appropriate.

Further, since the input of the background condition depends only on the manual operation of the controller, it is considered that the light intensity control and the blinking control may be delayed if the background state is suddenly changed.

The present invention has been made in view of the above circumstances, and an object thereof is to appropriately observe states such as background luminance and environmental conditions and automatically input the observation data, and to appropriately change the states. An object of the present invention is to provide an aviation lighting control device capable of performing various light intensity control and blink control.

It comprises a control processing unit for processing the light intensity switching timing, a notification unit for notifying the light intensity switching, an operation unit for inputting a switching permission signal, and a control output unit for controlling and outputting the proper light intensity data to the lighting equipment. Characterize.

[0008]

According to the aviation lighting control device of the present invention, the environmental data observation section automatically observes the data necessary for calculating the proper luminosity, takes this data into the data input section, and further corrects it by the arithmetic processing section. Different luminous intensity steps are calculated.
The result is supplied to the control processing unit, and when the calculation result of the appropriate brightness level changes, the notification unit is notified that the brightness level switching is to be performed. Is input, and proper light intensity data is controlled and output from the control output unit.

The present invention will be described below with reference to the drawings. Figure 1
FIG. 1 is a block diagram of an embodiment of an aviation lighting control device of the present invention. As shown in FIG. 1, the aviation lighting control device includes a plurality of environmental data observation units 1 a to 1 n and a plurality of data input units 2.
a to 2n, an arithmetic processing unit 3, a control processing unit 4, a reporting unit 5, an operation unit 6, and a plurality of control output units 7a to 7n.

The environmental data observing units 1a to 1n are installed near the end of the runway, and automatically observe the data necessary for calculating the appropriate luminous intensity such as the atmospheric transmittance and the transmission background luminance, and these data are input to the respective data input units 2a. ~ 2n. The data input units 2a to 2n take in the data output from the environmental data observation units 1a to 1n and supply the data to the arithmetic processing unit 3. The arithmetic processing unit 3 calculates an appropriate luminous intensity level from the value of the data output from each of the data input units 2a to 2n, and supplies this to the control processing unit 4.

The control processing unit 4 supplies the notification unit 5 with a signal indicating that the light intensity level switching should be performed when the appropriate light intensity level output from the arithmetic processing unit 3 is changed, and the operation unit 6 is operated. The switching permission signal output from the control output units 7a to 7n is supplied to the control output units 7a to 7n.

The notification unit 5 is installed in the control tower and takes in a signal output from the control processing unit 4 indicating that the light intensity step switching should be performed, and displays or alarms this signal to notify the controller. The operation unit 6 is installed in the control tower, takes in a switching permission signal input by a manual operation by the controller, and supplies this to the control processing unit 4. Each of the control output units 7a to 7n takes in the proper light intensity step to be controlled output from the control processing unit 4, and outputs this to the lighting equipment such as the CCRs 8a to 8n.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG. First, the environmental data observation units 1a to 1n installed near the end of the runway automatically observe atmospheric transmittance, lighting background brightness, etc., and this is the data input unit 2a to 1n.
It is taken in by 2n (step ST1), an appropriate luminous intensity step is calculated by the arithmetic processing section 3, and the result is supplied to the control processing section 4 (step ST2).

When the calculation result of the appropriate luminous intensity level is changed (step ST3), the notification section 5 installed in the control tower notifies the controller that the luminous intensity level should be switched (step ST4), and the control is performed. When the officer decides that the light intensity switching may be performed (step ST5), the switching permission signal is input from the operation unit 6 by the manual operation of the controller (step ST6), and the proper light intensity step to be controlled is controlled and output. Control output from the units 7a to 7n (step S
T7). If the calculation result of the proper light intensity step does not change in step ST3, the process ends. If it is determined in step ST5 that the controller does not need to switch the light intensity step, the controller again determines whether to switch the light intensity step. Is done.

As described above, in this embodiment, it is possible to automatically observe and automatically input the data such as the atmospheric transmittance and the lighting background brightness, and perform the appropriate luminous intensity step control following the changes in these states. .. In addition, there is no problem that the light intensity level switching is automatically performed while the aircraft is approaching by adding the judgment of the controller to the light intensity level switching timing. Although the light intensity stage switching timing command is given by the controller's judgment, the switching permission command may be automatically input by connecting to another air traffic control facility.
