Description

TECHNICAL FIELD [0001] The present invention relates to a Tunnel Luminance Meter,

The present invention relates to a system and method for distinguishing a tunnel luminosity abnormality, and more particularly, to a tunnel luminosity abnormality discrimination system and method capable of discriminating an abnormality of a luminosity system installed outside the two directions of a tunnel.

Generally, on public roads, illumination is needed only at night, but in tunnels, lighting is needed during the day.

When a driver who drives a vehicle enters a tunnel, he or she enters into a darker tunnel than the outdoors in a state of being acclimatized to the bright brightness of the outdoors. As a result of the sudden brightness difference, ) Phenomenon occurs.

Such dark accidents cause temporary blindness to the driver, leading to traffic accidents. Therefore, the lighting inside the tunnel is inevitable in order to protect the driver from the risk of traffic accidents. In this case, the tunnel lighting, which is the most ideal method, can illuminate the tunnel from the entrance to near the outdoor brightness and gradually reduce the illumination inside the tunnel according to the darkness of the snow.

In this way, a tunnel lighting system is installed to adjust the lighting inside the tunnel to match the darkness of the snow.

In Korea, the tunnel lighting standard is applied to reflect the tunnel lighting standards of the International Lighting Society and the North American Lighting Society. However, in the tunnel lighting design, the luminance reference table to which the conversion coefficient is applied is used. .

In other words, currently domestic tunnel lighting system is operated based on measured illuminance.

In general, the illumination of the tunnel is different according to the time, the outdoor lighting and the outdoor lighting are different from each other and the tendency to change with time is different. Therefore, according to the illumination system based on illumination, There is a problem that it is difficult to adapt to darkness when entering. In addition, the tunnel lighting is operated differently from the actual environment, and energy is wasted.

However, in general, the external brightness of the tunnel is measured from an external luminance meter installed at a distance from the reference point, with the stopping distance as a reference point from the entrance of the tunnel. Therefore, it is difficult to install a plurality of luminance meters outside the tunnel due to a practical problem such as a high cost of the luminance meter, although the reference point for measuring the luminance must be changed as the stopping distance changes as the speed limit changes .

In addition, there is a problem that an expensive luminance meter provided outside the bidirectional direction of the tunnel is difficult to detect and take action when an abnormality (malfunction or malfunction) occurs.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a system and method for determining a tunnel luminosity abnormality capable of controlling a tunnel illumination system based on luminance close to a luminance of an actual driver .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a system and method for distinguishing a tunnel luminance anomaly according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, in order to facilitate understanding and explanation, the luminance meter provided outside the two directions of the tunnel is referred to as an " external luminance meter ", and the same tunnel measuring the preliminary external luminance before measuring the luminance of the tunnel is referred to as & .

FIG. 1 is a conceptual diagram showing a tunnel luminance meter abnormality discrimination system according to an embodiment of the present invention, and FIG. 2 is a plan view showing a tunnel luminanceometer abnormality discrimination system shown in FIG.

As shown in FIGS. 1 and 2, the system for distinguishing a tunnel luminous intensity anomaly according to an exemplary embodiment of the present invention is installed apart from the entrance of the tunnel 10 by a stop distance to measure luminance outside the tunnel 10 A downstream luminance meter 210 disposed at a position corresponding to the upward luminance meter 210 and spaced apart from the inlet of the downstream tunnel 10 by a stop distance to measure luminance outside the tunnel 10; And an abnormality of the ascending luminance meter 210 and the descending luminance meter 220 in accordance with the luminance values of the ascending luminance meter 210 and the descending luminance meter 220 measured according to a weather condition And a controller 300 for calculating the first proper luminance difference 410 of the ascending luminance system 210 and the descending luminance system 220 in the same time zone.

The tunnel luminance meter abnormality determination system further includes a weather detector 350 for detecting a weather condition outside the tunnel 10, and an integrated control center 350 for receiving the weather condition detected by the weather detector 350 and the luminance value (340).

The tunnel 10 may be provided with an illumination 20 therein. An LED 20 may be used as the illumination 20 installed inside the tunnel 10. On the other hand, the control device 300 can perform dimming control of LEDs and the like from the entrance of the tunnel 10 to a predetermined interval based on the measured brightness value. Accordingly, it is possible to minimize the black hole phenomenon and the like to the driver who enters the tunnel 10 from outside the tunnel 10, thereby providing the driver with an optimal environment for the user.

The illumination 20 installed inside the tunnel 10 also has a service life, and in general, the illuminance 20 becomes weaker over time. The light loss factor represents the ratio of the average roughness (illuminance) of the work surface after the illumination 20 mechanism is used for a certain period of time to the average roughness at the time of installation.

When the illuminance of the illumination 20 becomes weak or the illuminance becomes weak over time, the luminance value falls within a certain period within the tunnel 10.

In addition, an internal luminance meter 100 is provided in the tunnel 10 to measure the luminance of the inside of the tunnel 10 by the controller 300.

When the luminance value falls within a certain period of the tunnel 10, the internal luminance meter 100 senses the luminance value, and the controller 300 monitors the luminance value measured by the internal luminance meter 100, ) To the tunnel 10 management station.

Therefore, the tunnel 10 station can easily replace the abnormal lighting 20.

The illumination 20 installed in the tunnel 10 is largely constituted by the tunnel entrance illumination unit 20, the basic illumination unit 20, and the exit illumination unit 20.

Most importantly, the entrance lighting 20 of the tunnel 10 is divided into a boundary portion, a transition portion, and a relaxation portion.

The boundary luminance value is preferably the same luminance as that required for the driver to observe an object in the tunnel 10 outside the tunnel 10 (not yet in a dark state), but the actual luminance value is preferably determined by the outdoor field luminance It depends on the rate determined by the speed. The ratio of setting the brightness value of the boundary portion can refer to the standard illustrated in Table 1. [

The luminance ratio of the boundary to the outdoor luminance (KS Standard 3703) Design Speed (Km / h) 100 80 60 Coefficient 0.07 0.05 0.04

In addition, the distance between these boundaries may vary depending on the design speed, but it is recommended that the distance be half of the braking distance in the Commission Internationale de l'Eclairage (CIE) report.

The transition portion is a section for giving a luminance background to an object to be observed in a state where the driver is still in the state where the tunnel 10 is still approaching while approaching the tunnel 10 and the illumination 20 of the section is also gradually formed do.

The relaxation part is a section for attenuating the luminance according to the adaptation from the end point of the transition part to the basic part to give the luminance background, which is also formed so that the illumination 20 is gradually reduced to complete the adaptation.

In other words, the illumination 20 of the transition portion and the relaxation portion is to gently reduce the gap between the boundary portion luminance and the basic portion luminance in accordance with the eye adaptation characteristic.

The tunnel 10 may be provided with an internal luminance meter 100 capable of measuring the luminance of the illumination 20. [

On the other hand, an ascending luminance meter 210 and a descending luminance meter 220 are installed outside the tunnel 10 to measure the luminance outside the tunnel 10.

At this time, the ascending luminance system 210 and the descending luminance system 220 are spaced apart from the entrance of the tunnel 10 by the stop distance SD.

The relationship between design speed and stopping distance is shown in Table 2 below.

Design speed Stopping distance 20 km / h 20m 30 km / h 30m 40 km / h 40m 50 km / h 55m 60 km / h 75m 70 km / h 95m 80 km / h 110m 100 km / h 155m

Therefore, on a road having a design speed of 100 km / h, the external luminance meter 200 is preferably installed at a distance of 155 m from the entrance of the tunnel 10.

When the external luminance meter 200 is used to measure the external luminance of the tunnel 10, the luminance can be measured using the L20 method or the optical film luminance method.

In the L20 method, the average luminance can be easily measured using a luminance meter having an opening angle of 20 [deg.]. In addition, the ratio of the background around the tunnel 10 including the tunnel 10 to the background image of the entrance of the tunnel 10 at the stopping distance can be evaluated, and the average outdoor luminance and the average luminance of the boundary connection at the entrance connection can be calculated.

The luminance method is a technique for accurately estimating the luminance value of the boundary of the tunnel 10 by using photometric and mathematical methods. Here, the luminance of the optical fiber means the total amount of luminance around the tunnel 10 that the eye must acclimate to when entering or exiting the tunnel 10, and the equivalent optical film brightness representing the luminance of the optical fiber due to scattering of light occurs in the glare meter You can measure directly with a special luminance meter equipped with a glare lens.

The external luminometer 200 includes an ascending luminometer 210 spaced from the entrance of the ascending tunnel 10 by a stopping distance to measure luminance outside the tunnel 10, And a downstream luminance meter 220 disposed at a position spaced apart from the inlet of the downstream tunnel 10 by a stop distance to measure the luminance outside the tunnel 10.

Uphill luminance meter 210 may refer to an external luminance meter 200 spaced a stop distance from the entrance of tunnel 10 in the direction from the bottom to the top of the vehicle, May be referred to as an external luminometer 200 spaced apart from the entrance of the tunnel 210 in the other direction by a stop distance.

Since the luminance values of the ascending luminance system 210 and the descending luminance system 220 may be different from each other due to the relationship between the orientation of the entrance of the tunnel 10 and the position of the sun, the upward luminance system 210 and the downstream luminance system The error range according to the difference in the luminance value of the system 220 can be set.

In addition, the external luminance meter 200 may include a transmitter 230 for transmitting the luminance value measured according to a weather condition to the controller 300.

The control device 300 controls the illumination 20 installed in the tunnel 10 based on the external luminance value of the tunnel 10 transmitted from the external luminance meter 200.

The control unit 300 includes a signal conversion unit 310 that receives the brightness value measured in the luminance meter as an electrical signal and a control unit that controls the lighting unit 20 using the electrical signal obtained from the signal conversion unit 310 And an illumination power source 330 for controlling the illumination 20 using the control signal output from the control unit 320.

The controller 300 receives the luminance value measured in the luminance meter as an electric signal, converts the luminance value into a multi-level digital signal through the signal converting unit 310 and sends the digital signal to the controller 320, 320 analyzes the luminance value and provides a control signal to the output conversion unit 321 according to a preset luminance value.

The output conversion unit 321 converts the control signal into an electric signal and controls each light 20 through the relay 20 of the illumination power supply unit 330.

The control device 300 also includes a communication unit. Therefore, it is possible to monitor and control the operation state of the illumination 20 remotely by changing to a general-purpose communication signal through the communication unit.

FIG. 3 is a graph illustrating a change in luminance value of each season according to an embodiment of the present invention, and FIG. 4 is a graph illustrating a temporal relationship of intensity values of a tunnel in both directions according to an embodiment of the present invention.

3 to 4, a system for distinguishing an anomaly of a tunnel luminous intensity meter according to an embodiment of the present invention includes an ascending / descending A luminance meter 210 and a downstream luminance meter 210 disposed at a position corresponding to the upward luminance meter 210 and spaced apart from the entrance of the downstream tunnel 10 by a stop distance to measure the luminance outside the tunnel 10 220 may be provided.

The graph shown in FIG. 3 may show a constant relationship with each season, and the winter (FIG. 3A) may have a lower luminance value, and the spring and autumn (FIG. 3B) may have a higher luminance value than the winter. In the summer (C in Fig. 3), the luminance value is measured to be the highest, and a constant relationship can be seen according to the season.

The external luminance of the tunnel 10 is measured through an external luminance meter provided at a distance from the reference point, with the stopping distance from the entrance of the tunnel 10 as a reference point. Therefore, since the stopping distance is 155 m at a speed limit of 100 km / h, the luminance should be measured through the external luminance meter (200) installed at a distance of 155 m from the entrance of the tunnel (10), while the visibility distance The stopping distance at a speed limit of 50 km / h is 55 m, so the luminance should be measured through an external luminance meter 200 installed at a distance of 55 m from the entrance of the tunnel 10.

The luminance values of the entrance and exit of the tunnel 10 and the entrance of the tunnel 10 can be divided into an upward direction and a downward direction according to the direction of the tunnel 10, Due to the relationship of position (altitude, incidence direction, etc.), differences may occur at the same time. Thus, the external luminance meter 200 in each direction must be separately provided. In general, since the luminance meter is expensive, it is difficult to install a luminance meter in each direction and distance.

3, the external brightness values of the tunnels 10 in both directions are shown to be constant according to season, month, time, and weather conditions. The external brightness of the tunnels 10, May also have a similar external luminance distribution in the case of an adjacent tunnel 10 whose orientation is similar.

As shown in FIG. 4 (a), the upward luminance meter 210 and the downstream luminance meter 220 can apply an error range between the ascending luminance meter 210 and the descending luminance meter 220, 210 and the downstream luminance system 220 can be referred to as a measured luminance difference 240. [

The measured luminance difference 240 sets an error range of the measured luminance difference 240 based on a standard relationship between the luminance values of the ascending luminance meter 210 and the descending luminance meter 220, It is possible to determine errors and defects in the downstream luminance meter 210 and the downstream luminance meter 220.

If an abnormality occurs in the external luminance meter 200 including the ascending luminance meter 210 and the descending luminance meter 220, the external luminance value can not be accurately measured and the lighting 20 in the tunnel 10 can not be accurately controlled Therefore, the black hole phenomenon of the driver may occur.

For example, the illumination 20 of the present invention can prevent the black hole phenomenon of the driver by adjusting the brightness of the illumination 20 by the luminance value measured by the external luminance meter 200, If the brightness of the illumination 20 in the tunnel 10 is adjusted in the controller 300 without detecting the occurrence of the abnormality, the black hole phenomenon of the driver may occur.

However, some of the mechanical and electrical anomalous indications of the external luminance meter 200 can be discriminated by mechanical or electrical signals. However, various other foreign substances such as condensation, moisture, pollution, When all or part of the front window of the external luminance meter 200 is covered due to sticking to the front window of the system 200, it may be impossible to discriminate through mechanical or electrical signals.

Therefore, when it is difficult to discriminate the mechanical and electrical signals in the external luminance meter 200, the luminance database 500 including the luminance values of at least one of the season, month, and time of the external luminance meter 200 is accumulated The control unit 300 compares the luminance value provided by the integrated control center 340 with the luminance difference between the ascending luminance system 210 and the descending luminance system 220 received by the controller 300, It can be judged. Then, the integrated control center 340 can provide the control device 300 with a weather database for weather conditions.

4B, the control device 300 transmits a reference tunnel to the same tunnel 10 as the tunnel 10 before discriminating the abnormality of the ascending luminance system 210 and the descending luminance system 220, (400) may be applied to compare the external brightness. The controller 300 may measure the brightness of the reference tunnel 400 and may manually and automatically set the first proper luminance difference 410 to the measured luminance difference 240 for the difference in luminance value. It can be determined that an abnormality has occurred in the ascending luminance meter 210 and the descending luminance meter 220 when the measured luminance difference 240 is out of the error range of the first proper luminance difference 410. [

FIG. 5 is a graph illustrating a relationship between luminance values measured in the same direction luminance meter of a reference tunnel according to an exemplary embodiment of the present invention. Referring to FIG.

Referring to FIG. 5, the integrated control center 340 according to an embodiment of the present invention includes a brightness database 500 in which the brightness values of at least one of the season, month, and time of the weather sensor 350 are accumulated .

The reference tunnel 400 may measure the external luminance and store the luminance value in the integrated control center 340 in order to reserve the data before measuring the luminance of the tunnel 10.

The brightness value of the reference tunnel 400 may be variously stored according to at least one weather condition among season, month, and time zone of the weather detector 350.

The integrated control center 340 also has a brightness database 500 in which the brightness values of the reference tunnel 400 and at least one of the season, month, and time of the weather sensor 350 are accumulated can do.

The luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are related to the luminance values measured by the ascending luminance system 210 and the descending luminance system 220, And may be stored in the control center 340.

The luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220 are stored in the luminance meter 500 210 and the second optimal luminance difference 510 of the reference tunnels of the downstream luminance system 220.

The second appropriate luminance difference 510 is calculated by subtracting the luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220 from the upward luminance meter 210 ) And the luminance value of the downward luminance meter 220. In this case, At this time, the second optimum luminance difference 510 is stored in the luminance database 500 as a difference between the maximum luminance value and the minimum luminance value in accordance with the time of each of the luminance meters 210 and 220 of the same direction reference tunnel .

When the luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are out of the error range of the second optimum luminance difference 510, 5, the second optimum luminance difference 510 of the luminance database 500 stored in the integrated control center 340 and the second optimum luminance difference 510 of the up luminance meter 210 and the downstream luminance meter 220 are measured It is possible to detect an error and a defect by comparing the luminance value 211 of the ascending luminance meter 210 with the luminance value 221 of the descending luminance meter 220.

At this time, the integrated control center 340 determines whether or not the luminance database 500 of the same time zone and the same direction as the luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220, . ≪ / RTI > Also, the brightness database 500 having the same state as that of the up-stream luminance meter 210 and the down-flow luminance meter 220 can be used.

FIG. 6 is a graph illustrating a relationship between the third optimal luminance difference 610 of the pseudo tunnel 600 according to an embodiment of the present invention.

Referring to FIG. 6, the similar tunnel 600 according to an embodiment of the present invention may be an adjacent tunnel 10 similar to the direction of the bidirectional entrance, which is similar for each season, month, time, and weather condition.

If the luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220 deviate from the error range of the second optimum luminance difference 510 of the reference tunnel, 210) and the downstream luminance meter (220).

The luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are measured at the same time in the similar tunnel 600, Can be compared with the error range of the car 610.

If the luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the downstream luminance meter 220 are out of the error range of the third optimum luminance difference 610, Of the ascending luminance system 210 and the descending luminance system 220 are different from the luminance system of the similarity tunnel 600 or the luminance database 500, The system 200 can be corrected.

Hereinafter, the same reference numerals will be used for the same components as those of the tunnel luminous intensity anomaly determination system according to the above-described embodiment in explaining a method for distinguishing a luminance of a tunnel 10 according to another embodiment of the present invention, The description is omitted.

FIG. 7 is a flowchart illustrating a method of determining a tunnel luminance meter abnormality according to another embodiment of the present invention, and FIG. 8 is a graph illustrating a temporal change in luminance according to another embodiment of the present invention.

In steps S100 to S200, the reference tunnel 400 can be set to measure the external weather conditions of the reference tunnel 400 and the bidirectional external luminance values of the reference tunnel 400 by the weather detector 350 of the reference tunnel 400 have.

In step S300 to step S400, the weather condition and the external brightness value of the reference tunnel 400 may be stored in the integrated tanker center to store the brightness database 500. The integrated control center 340 may store the brightness database 500 It is possible to calculate the first proper luminance difference 410 to be provided for discriminating the abnormality of the ascending luminance system 210 and the descending luminance system 220 in the control apparatus 300. [

Since the first proper luminance difference 410 may be calculated using manual or automatic analysis and since there is no luminance value measured in the tunnel 10 at the beginning of installation of the external luminance meter 200 of the reference tunnel 400, Can be applied by various methods such as relational tables and mathematical expressions.

However, after a certain period of time has elapsed since the installation of the ascending luminance system 210 and the descending luminance system 220, information of the luminance database 500 may be analyzed to correct and supplement the first proper luminance difference 410 .

In step S500, the luminance value can be measured in the ascending luminance meter 210 and the descending luminance meter 220 provided in both directions of the tunnel 10 to measure the luminance.

The luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220 measured in step S500 are calculated by the difference of the respective luminance values in the controller 300 in step S600 The measured luminance difference 240 can be calculated.

In step S700, the control device 300 analyzes whether the measured luminance difference 240 falls within an allowable tolerance range in the first proper luminance difference 410 and determines whether the abnormality of the ascending luminance meter 210 and the descending luminance meter 220 Can be distinguished.

At this time, if the measured brightness difference 240 is within the error range of the first proper brightness difference 410, the external brightness value of the tunnel 10 can be measured.

In step S800, when the measured brightness difference 240 deviates from the first proper brightness difference 410, the brightness database 500 stored in the integrated control center 340 uses the manual or automatic analysis to calculate the second optimal brightness The difference 510 can be calculated. The difference between the measured luminance difference 240 and the luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are different from each other, The abnormality of the ascending luminance meter 210 and the descending luminance meter 220 can be discriminated.

At this time, if the measured brightness difference 240 is within the error range of the first proper brightness difference 410, the external brightness value of the tunnel 10 can be measured.

In step S900, the measured luminance difference 240 and the luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are transmitted to the reference tunnel 400 in the same direction, The second tuning brightness difference 510 of the tunnels 10 is similar to the geomorphological conditions such as the azimuthal directions of the bidirectional entrance of the tunnel 10 and is similar to that of the adjacent tunnels having a constant relationship by season, (600) can be selected.

The measured luminance difference 240 and the luminance value 211 of the ascending luminance system 210 and the luminance value 221 of the descending luminance system 220 are compared with the luminance value measured in the similar tunnel 600 The abnormality of the ascending luminance system 210 and the descending luminance system 220 can be discriminated by analyzing whether the difference is within the error range of the third appropriate luminance difference 610 calculated by the above equation.

In step S1100, the third optimum luminance difference 610 of the similar tunnel 600 among the ascending luminance system 210 and the downstream luminance system 220 is compared with the external luminance system 200 deviating from the error range, It is possible to inform the external brightness meter 200 that an abnormality is found in the station of the tunnel 10 to make corrections.

The ascending luminance meter 210 and the descending luminance meter 220 are corrected so that the ascending luminance meter 210 and the descending luminance meter 220 are shifted from the first proper luminance difference 410 to the third right luminance difference It is possible to judge whether an out-of-range error range of the luminance change pattern 610 is a temporary and abrupt luminance change pattern.

If the luminance value 211 of the ascending luminance meter 210 and the luminance value 221 of the descending luminance meter 220 are repeated temporarily and suddenly the luminance change is repeated, (Maximum, minimum, average, and the like) of the brightness in the same direction in the same period of time and the present observation brightness in the same direction in the same period of time The brightness change pattern according to the brightness change pattern may also be considered simultaneously. If these two conditions are similar to the currently measured luminance, it can be determined that the two-way luminance relationship is not abnormal even though it is different from the predefined relationship. In this case, a larger value of 'the external brightness in the corresponding direction (considering the safety factor) by the relation between the' maximum luminance 'and the' external luminance in the other direction ' Normal operation can be judged.

In addition, when an event in which the upward luminance system 210 and the downward luminance system 220 are temporally or locally changed in luminance, such as a cloud, only the luminance in one direction is greatly changed. As a result, And the possibility of discrimination is greater than the luminance system, the algorithm shown in Fig. 8 can be applied.

As shown in the graph of FIG. 8, the ascending luminance meter 210 and the descending luminance meter 220 comprehend a luminance variation pattern according to a time change in a specific weather condition such as a cloud and compare it with the current measured value (B in FIG. 8) The up luminance meter 210 and the downflow luminance meter 220 can be corrected.
