Description

Portable light calibrator for light quantity calibration of lantern illuminance sensor and method for light quantity calibration of lantern illuminance sensor using the same }

The present invention relates to a technology for calibrating the amount of light of an illuminance sensor of a lantern installed on a coast or sea for navigational aids, and more particularly, by measuring the amount of light of an illuminance sensor that determines whether the lantern is turned on or off. The present invention relates to a portable luminance calibrator for calibrating the luminous intensity of a lantern illuminance sensor and a luminous intensity calibration method using the same, which can reduce the time and cost required for calibrating the lantern by simply calibrating it in the field without disassembling and assembling the lamp.

Various types of navigation lights are installed to safely guide ships on the sea or coast where ships enter and depart frequently, and to easily identify and recognize geographical features or port locations on the sea at any location. is being operated

Such lanterns must have straightness and divergence (diffusibility) so that they can be identified from a long distance and have excellent night visibility. In addition, they are manufactured in various structures and standards so that the amount of light required is different depending on the installation place, and an example thereof is shown in FIG. 1.

1 is a cross-sectional view schematically shown to explain a lantern according to the prior art.

Referring to FIG. 1, a lantern 10 according to the prior art includes a lower light body 11 and an upper light body 12 that are assembled vertically. An analog illuminance sensor (light amount sensor) 13 and a power supply unit 14 are installed in the lower light body 11, and a control module 15 is installed inside. An LED module 16 is installed inside the upper light body 12, and a GPS antenna 17 is installed on the top.

In addition, a solar panel (not shown) for supplying power using solar energy is additionally installed in the lower light body 11, and a storage battery (battery) for storing power generated from the solar panel is installed therein. It can be. The control module 15 may receive power obtained through a solar panel as power or power stored in a storage battery.

The control module 15 controls the operation of the LED module 16 according to the amount of light detected by the illuminance sensor 13 . The illuminance sensor 13 senses the amount of light, cuts off the power supplied from the power supply unit 14 during the day, and supplies power during the night. That is, the illuminance sensor 13 turns on the LED module 16 by supplying power through the power supply unit 14 after sunset. The lighting operation range of the LED module 16 is 50 to 100 Lx, and the lighting operation range is managed as an absolute light amount, such as 150 to 200 Lx.

As the illuminance sensor 13, an analog type cadmium sulfide (CDS) sensor is mainly used. The CDS sensor is an analog type sensor in which a resistance value is changed according to a change in the amount of light, and outputs a voltage corresponding to the measured amount of light after measuring the amount of light. Because such a CDS sensor has a large voltage deviation according to the amount of light measured for each sensor, it cannot be used immediately even if it is replaced with a new product in the event of a malfunction or measurement error, and the lamp must be calibrated. The calibration of the lamp is a task of resetting the lantern according to the characteristics of the CDS sensor to be replaced, and resetting the lamp to an output voltage according to the amount of light measured by the CDS sensor to be replaced.

However, the replacement work is cumbersome because the process of disassembling and assembling the upper and lower lights of the lantern is essential for correcting the lantern. In particular, since the lantern is installed and operated on a marine structure (eg, a buoy) that is relatively difficult for workers to access, the calibration work of the lantern requires considerable labor and cost.

Hereinafter, technical features of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic block diagram of a portable light intensity corrector according to an embodiment of the present invention.

Referring to FIG. 2 , a portable light intensity corrector 30 according to an embodiment of the present invention is a device for calibrating the light intensity of the illuminance sensor 21 for turning on and off the lantern 20 .

As described above, the illuminance sensor 21 for the lamp 20 is installed in the lamp 20 to turn on and off the LED module 22 for the lamp according to the light intensity value (operation range) set during the day and at night.

The illuminance sensor 21 for the lantern can use a digital illuminance sensor that can reduce maintenance cost and time compared to a conventional lantern in which an analog illuminance sensor is installed.

The digital illuminance sensor directly outputs the measured light quantity as lux (Lx), not as a voltage, unlike an analog illuminance sensor. That is, by directly outputting and providing the measured amount of light as lux (Lx), it is possible to reduce the measurement error pointed out as a problem in the analog type illuminance sensor. Here, 1 lux means when a luminous flux of 1 Lm is uniformly illuminated on an area of 1 m ² .

That is, since the digital illuminance sensor has less variation according to the temperature of the surrounding environment than an analog type illuminance sensor such as CDS, measurement error can be reduced. Accordingly, it is possible to provide an advantage of reducing the frequency of calibration work compared to an analog type illuminance sensor.

As shown in FIG. 2, the illuminance sensor 21 for a lantern is protected by a housing 21a and a cover 21b. Since the cover 21b is usually made of a transparent material, for example, a transparent synthetic resin material, aging or deterioration during long-term use affects light incident to the sensor.

Therefore, even in the case of the illuminance sensor 21 for a lantern made of a digital illuminance sensor, an error may occur in the amount of light measured by the illuminance sensor 21 for a lantern due to aging or deterioration of the cover 21b. 21), it is also necessary to calibrate the amount of light.

The portable light intensity corrector 30 according to an embodiment of the present invention includes a darkroom box 31 in which a darkroom 31a is provided for an environment for adjusting the light intensity of the illuminance sensor 21 for a lantern.

3 is a diagram schematically showing a darkroom box according to an example of the present invention.

As shown in FIG. 3 , the darkroom box 31 may be formed of a hexahedron in which a darkroom 31a is provided, for example, a cube or a cuboid. An insertion hole 31b is formed on the rear side of the darkroom box 31 so that the illuminance sensor 21 for the lamp installed in the lamp 20 is inserted into the darkroom 31a.

Insertion port (31b) may be made of a circular, elliptical or prismatic, etc. In addition, it may be formed in various shapes. The insertion hole 31b needs to be sealed while the housing 21a of the light sensor 21 for a lantern is inserted so that outside light does not flow into the darkroom 31a. To this end, the housing 21 of the illuminance sensor 21 for a lamp should be closely adhered to the inner surface of the insertion hole 31b so that the housing 21a is tightly fitted to the inner surface of the insertion hole 31b.

To this end, the inner surface of the insertion hole 31b should have a shape corresponding to the outer surface of the housing 21a of the illuminance sensor 21 for a lantern. For example, as shown in (b) of FIG. 3, when the outer surface of the housing 21a of the illuminance sensor 21 for a lantern has a hexagonal structure, the inner surface of the insertion hole 31b must have a hexagonal structure correspondingly. In addition, for the airtightness of the insertion hole 31b, a ring-shaped elastic member, for example, a hexagonal ring-shaped elastic member is additionally installed on the inner surface of the insertion hole 31b or the outer surface of the housing 21a of the illuminance sensor 21 for lanterns.

In addition, as a standard light quantity sensor for calibrating the operating range of the lantern 20 according to the light quantity of the lamp illuminance sensor 21, for example, the light quantity of the LED module 22 for the lantern, it is composed of a digital illuminance sensor.

When arranging the calibration illuminance sensor 33 in the darkroom 31a, the calibration illuminance sensor 33 is calibrated to the distance between the calibration LED module 32 and the lamp illuminance sensor 21 in the darkroom 31a. The distance between the calibration LED module 32 and the calibration illuminance sensor 33 is the same, and the angle at which light is irradiated from the calibration LED module 32 to the lantern illuminance sensor 21 and the calibration LED module 32 ), it can be arranged so that the angle at which light is irradiated to the illuminance sensor 33 for calibration is the same. This is to enable the illuminance sensor 33 for calibration and the illuminance sensor 21 for lantern to measure the amount of light in the same environment (condition). For example, the LED lamp 32a of the LED module 32 for calibration may be disposed at the center of the illuminance sensor 21 for a lantern and the illuminance sensor 33 for calibration.

It can be set to a brightness corresponding to the middle value of 175Lx in the operating range of 150~200Lx.

The light quantity value measured by the illuminance sensor 21 for the lantern is directly input to the control module 23 for the lantern in units of lux (Lx), and the control module 23 for the lantern is the light quantity input from the illuminance sensor 21 for the lantern According to this, the operation of the LED module 22 for the lamp is controlled through the LED operation switch 24.

The illuminance sensor 33 for calibration is a digital illuminance sensor like the illuminance sensor 21 for a lantern, and the measured light quantity value is directly output in units of lux (Lx) and input to the control module 34 for calibration.

The input display window 35 may be installed on the front of the darkroom box 31 and may be formed of a touch display panel to provide an interface with an operator. For example, the input display window 35 displays the brightness of light provided by the calibration LED module 32, and adjusts the brightness of the calibration LED module 32 with a 'brightness decrease button (-)' and a 'brightness Increase button (+)' is provided. In addition, the brightness of the increased or decreased light is displayed step by step through the 'brightness decrease button' and 'brightness increase button'. In addition, before calibration, the operation range when the LED module 22 for the lantern 22 is turned on and off, that is, the light quantity value, and the light quantity measured by the calibration illuminance sensor 33 and the lantern illuminance sensor 21 for the light quantity calibration, respectively The light intensity value is expressed as lux (Lx). In addition, 'day setting' and 'night setting' buttons are provided to correct the amount of light when the LED module 22 for the lamp is turned on and off, and a 'save setting' button is provided to store the determined final light amount value as a set value. .

For example, as shown in FIG. 6, in relation to turning off the light of the LED module 22 for the lamp, pressing the 'day setting' button resets and corrects the light intensity value of the illuminance sensor 21 for the lamp, and the LED module 22 for the lamp ) is calibrated by re-setting the light intensity value of the illuminance sensor 21 for the lantern. When the setting of the light intensity value of the illuminance sensor 21 for the lantern for day and night is completed through the 'day setting' button and the 'night setting' button, press the 'save setting' button to complete the setting of the illuminance sensor for the lantern ( 21) to finalize the light intensity value to complete the calibration work.

The control module 23 for the lantern may provide the amount of light measured by the illuminance sensor 21 for the lantern to the control module 34 for calibration through the communication unit 25 for the lantern and the communication unit 36 for calibration. In addition, the control module 34 for calibration includes the amount of light measured by the illuminance sensor 21 for the lantern provided from the control module 23 for the lantern through the communication units 25 and 36 and the amount of light measured by the illuminance sensor 33 for calibration.

As shown in FIG. 6, a dark box 31 is installed to cover the illuminance sensor 21 for the lantern installed on the lower lamp body 20b of the lantern 20. In the installation method of the darkroom box 31, the illuminance sensor 21 for a lantern is installed so that it is inserted into the darkroom 31a through the insertion hole 31b of the darkroom box 31.
