The technical characteristics of the LED indicator 170 that can be extended, and the technical characteristics of the solar cell to make it possible to achieve the capacity expansion very easily when necessary to increase the power capacity required to drive the bus platform safety system.

2 and 3 illustrate an example of a bus platform in which a bus platform safety system according to the present invention is constructed, and FIG. 2 illustrates a view of the bus platform from above, and FIG. 3 illustrates a view of the bus platform from below. It is shown.

1 and 2, the bus platform safety system of the present invention is basically configured based on the solar cell 100 and the storage battery 105. The solar cell 100 is preferably installed on the upper surface of the bus platform roof (5), generates electricity by the photovoltaic effect when exposed to sunlight, the basic power required to drive the bus platform safety system of the present invention Corresponds to the power supply means for producing.

The storage battery 105 of the present invention is installed on the bus platform roof 5 together with the solar cell 100 so that the power from the solar cell 100 after sunset is charged with the power charged by the solar cell 100 at sunshine hours. When there is no, cloudy days, when the output of the solar cell 100 is insufficient, such as when raining to supply power to the load. The storage battery 105 may use a lead-acid battery or a nickel-cadmium battery as a secondary battery.

LED lighting 160 of the present invention is preferably installed on the lower surface of the bus platform underground corresponds to the lighting means to brighten the interior of the bus platform in the dark night. The LED lighting 160 uses an LED lamp composed of a plurality of LED (LED) elements as a light source. The bus platform safety system of the present invention has been described and illustrated by employing an LED lamp as a lighting means, but is not necessarily limited thereto. For example, a tungsten light bulb, a halogen lamp, and a cold cathode fluorescent lamp (CCFL) may be used. However, it is preferable to use an LED lamp having a low driving voltage and low power consumption and high luminance.

On / off operation and mode selection of the LED lighting 160 is controlled by the controller 150, which is connected to the illumination sensor 130 and the human body sensor 120 is input from these The operation of the LED lighting 160 is controlled based on the detection signal.

4 is a flowchart illustrating a control flow of the LED lighting 160 and the LED indicator 170 that operate in connection with the human body sensor 120 of the bus platform safety system according to the present invention. 1 and 4, the illumination sensor 130 is an element for determining the on / off of the LED lighting 160, the human body sensor 120 to determine the detailed lighting mode of the LED lighting 160 Corresponds to the element for That is, the controller 150 turns off the LED illumination 160 when the illumination information detected by the illumination sensor 130 corresponds to the day, and when the detected illumination information corresponds to a night or a cloudy day, the LED By turning on the lighting (160) it is possible to automatically control whether the lighting operation according to the day, night or rainy weather cloudy day / summer.

In addition, the LED lighting 160 operates to vary the brightness of the lighting according to the presence or absence of a person in the bus boarding area. In other words, if a person is present in the platform at night, lighting is performed at 100% illuminance (hereinafter, referred to as normal mode). If no human is present, less than 100% illuminance (preferably 20% illuminance) It is characterized by operating in the following (hereinafter referred to as a power saving mode). That is, the controller 150 controls the LED lighting 160 to operate in the normal mode when the human body sensor 120 receives a signal indicating that a person is present inside the platform, and receives a signal that the person is not present in the platform. LED lighting 160 is controlled to operate in a power saving mode.

The human body sensor 120 is for detecting the presence of a person inside the bus platform structure, and detects the motion of an object by irradiating infrared rays, or detects the presence of a person by detecting body temperature, and the like. At least one human body sensor 120 is preferably installed in the bus platform (for example, the lower surface of the roof 5). This is because it is best to ensure the safety of the passengers, at least configured to operate in normal mode when there is a person inside the bus platform.

In addition, the timer may be linked to the controller 150 so that the LED light 160 may be turned off or on unconditionally in a time zone set to the timer regardless of illuminance. For example, if the bus non-operation time (12 o'clock to 4 o'clock), even if the illumination information input from the illumination sensor 130 corresponds to the ON of the LED light 160, the off time zone (12 o'clock to 5 o'clock) set in the timer H) control the LED lighting 160 in the off state.

Further, even when the LED lighting 160 is turned off in the off time period set in the timer, when the human body sensor 120 receives a signal that a person is present, the off control by the timer is temporarily ignored. LED lighting 160 may be operated again to provide lighting to a person around the platform.

As such, the LED indicator light 170 provided at a relatively high place in the bus stop is not only inside the platform, but also at the front of the roadway (Fig. 2; K1) and at the night, such as the side area of the platform, even if the bus driver illuminates the interior of the platform at night. The optical display function is performed on an area (hereinafter, referred to as a blind spot) in which it is not easy to visually recognize the presence of a person.

That is, when the controller 150 receives a signal indicating that a person is present in the platform or blind spot from the human body sensor 120, the LED indicator 170 is turned on to provide a light indication indicating the presence of passengers to the bus driver. In addition, the LED indicator 170 turns off when the signal indicating that there is no person in the inside of the platform and the blind spot is provided, thereby providing a light indication informing the bus driver of the absence of the passenger. In addition, the LED indicator 170 may be turned on to continuously emit light of a specific wavelength or may be turned on in a flashing manner in which the lamp blinks at short intervals.

As described above, the human body sensor 120 provided in the bus platform safety system of the present invention is linked to the LED light 160 as well as the LED indicator 170. However, in the case of the LED indicator light 170, the human body detection for the blind spot as well as the inside of the bus platform is required, at least the human body sensor 120 associated with the LED indicator light 170 is installed in plurality Therefore, it is preferable that the passengers be configured to be able to detect the present situation even in a blind spot. In particular, most bus platform structures installed on rural roads or country roads have side pillars of walls, so when a passenger stands outside the walls, the human body sensor 120 installed on the platform roof 5 detects this. This can happen if you do not. Therefore, in addition to the human body detection sensor 120 is installed inside the landing hall further installed a human body detection sensor 120 having a sensing area on the outer side of the pillars on both sides of the landing and the roadway (FIG. 2; K1) and these display at least the LED It is preferable to configure such that it is associated with the back (170).

In addition, the LED indicator light 170 according to the present invention has a technical feature that can realize the optical display of 360 ° omnidirectional with only one LED chip, and greatly expand the visibility while minimizing power consumption and device volume. A detailed description thereof will be described later.

A charge coupled device (CCD) capable of storing or transmitting digital imaging information may be configured to employ imaging means (for example, CCTV), and to mount a large memory such as SD RAM to check recording contents after detachment. .

The security camera 180 is associated with the illumination sensor 130 and the human body sensor 120, and is preferably installed inside the bus platform to perform a recording function at night. That is, the controller 150 turns off the security camera 180 when the illuminance information detected from the illuminance sensor 130 corresponds to the day, and the crime prevention camera when the detected illuminance information corresponds to the night. By turning on (180) to protect the passenger's body at night.

In addition, the controller 150 controls the on / off operation of the security camera 180 according to the day / night based on the illumination sensor 130 as described above, and at the same time the human body sensor 120 provided in the platform ) To control the detailed operation of the camera as follows.

The controller 150 pauses the recording function of the security camera 180 when receiving a signal from the human body sensor 120 that there is no person around the bus stop, and receives a signal indicating that a person exists. Take control to re-enable. Therefore, the security camera 180 of the present invention operates to perform the recording function only at night, but if there is no person around the bus platform at all, even if the night stops the recording function to increase the recording standby time and equipment efficiency Characterized in that configured to be.

The smoking sensor 140 of the present invention corresponds to an element installed inside a bus platform and outputting a pre-recorded voice or sound when a smoke is detected by a passenger waiting around the platform to alert the corresponding smoker.

That is, when the control unit 150 receives the smoking detection signal from the smoking sensor 140, the controller 150 controls the audio output device 190 (for example, a speaker) to recommend a smoking or sound through the sound output device 190 (for example, a speaker) installed in the bus platform. Allow people to quit smoking in bus stops.

However, when the LED light source is configured as an LED light source to inform the bus driver as a light indication that a passenger is present in the bus stop, the light display range is limited to a very narrow viewing angle range due to the linearity of the LED light beam. To overcome this problem, a large number of LED elements should be installed, but each LED element should be arranged in a different direction to overcome the limitations due to the linearity of the LED light.

However, in this case, the following other problems and disadvantages are caused. That is, in order to display the omnidirectional light, a large number of LED elements must be installed in each direction in a hermetic manner, and power consumption is increased to repeatedly drive such a large number of LED elements for a long time.

The LED indicator light 170 of the bus platform safety system of the present invention is configured to implement a very wide light display range (maximum 360 °) while using only one LED element to solve the above problems.

Prior to the detailed description of the present invention, the term "expansion of visibility" used below is as follows. That is, the LED light rays emitted from one LED element 41 are narrow and deflected due to their straightness, so that the LED light display can be recognized only in one direction, and the position is off the optical axis of the LED element 41. In LED, it is difficult to recognize the LED light display, and the visibility to the light display is limited to a narrow range. This “expansion of visibility” means that the perceivable range (ie visibility) of the light display of the LED element 41 can be greatly extended in both directions on the optical axis, as well as in the rear range as necessary, so that it can be extended up to 360 °. This means that the LED light can be recognized.

In addition, the term "optical axis" used below means the central axis | shaft of the light propagation path | route of the LED light radiate | emitted and going straight from the LED element 41 provided in the lower part of a transparent tube.

7 and 8, the LED indicator of the bus platform safety system according to the present invention is a transparent tube 30, tube cap 10, the first reflecting member 20, LED module 40 and the body 50 ).

The transparent tube 30 of the present invention is configured in a cylindrical shape made of ordinary glass, tempered glass or transparent plastic material. In particular, when using a plastic material, it is preferable to use at least one selected from transparent resin materials such as polycarbonate (PC), polyethylene terephthalate (PET), and polymethyl methacrylate (PMMA). More preferably, it is preferable to use a material having a relatively high strength while having a high visible light transmittance of at least 85% or more, such as polycarbonate (PC).

According to the present invention, the LED light emitted from one LED element proceeds to form a radiation angle in all directions of the north, south, east, and west instead of one direction, and the transparent tube body 30 of the present invention is configured in the form of a transparent window. All the light reflected from all directions through the transparent tube 30 to be emitted to the outside. That is, as shown in FIG. 7, the inside may be configured to have an empty transparent cylindrical shape, so that up to 360 ° omnidirectional light display can be performed.

In addition, the transparent tube body 30 of the present invention is characterized in that the opening is formed at the top and bottom, respectively. The upper opening corresponds to an element for introducing the first reflective member 20 into the transparent tube 30, and the lower opening corresponds to an element for introducing the LED module 40 into the transparent tube 30.

The tubular cap 10 of the present invention is configured to be detachably coupled / removable to the upper opening of the transparent tubular body 30, and the first reflecting member 20 is provided below the tubular cap 10. In particular, the LED indicator light 170 of the present invention forms a male thread 11 on the outer circumferential surface of the tubular cap 10 for detachable coupling / separation of the tubular cap 10 and the arm on the inner circumferential surface of the upper end of the transparent tubular body 30. The thread 31 was formed so that a predetermined portion (male thread forming part) of the tubular cap 10 was inserted into the transparent tubular body 30 while being screwed to the upper end of the transparent tubular body 30. However, contrary to the above, the male thread is formed on the inner circumferential surface of the tubular cap 10 and the female thread is formed on the outer circumferential surface of the upper end of the transparent tubular body 30 so that the tubular cap 10 covers the outer circumferential surface of the upper end of the transparent tubular body 30 and is fastened with screws. Of course, it can also be configured as a structure. In addition, in addition to the above-described screw fastening method, some of the body 50 of the tubular cap 10 may be made to fit snugly to the top opening of the transparent tubular body 30 and may be configured to be detachably coupled in an interference fit manner.

When the tubing cap 10 is completed, the upper opening of the transparent tubular body 30 is closed by the tubular cap 10, and the first reflective member 20 mounted below the tubular cap 10 is the transparent tubular body 30. ) Is kept in the upper region of the interior.

Even if the tubing cap 10 is firmly coupled to the transparent tubular body 30, a slight gap is generated at the joining boundary, so that rainwater or water may invade into the transparent tubular body 30, and thus, the tubular cap 10 is in the transparent tubular body 30. Bare moisture may cause device failure, the tubular cap 10 is preferably further provided with a rubber packing (35). Rubber packing 35 according to the embodiment of Figure 7 is formed in the O-ring shape made of the same shape and diameter as the upper opening of the transparent tube 30, the O-ring when the tube cap 10 and the transparent tube 30 is combined Rubber packing 35 in the form is arranged along the perimeter of the coupling boundary was configured to fill the gap.

The first reflective member 20 of the present invention is attached to the lower portion of the tubular cap 10 when the tubular cap 10 is coupled to the transparent tubular body 30 is introduced into the tubular body, and the tubular cap 10 is inserted into the transparent tubular body 30. The first reflective member 20 is configured to face the LED element 41 provided below the transparent tube 30 at a predetermined interval. That is, when the coupling of the tubular cap 10 equipped with the first reflective member 20 to the upper opening of the transparent tubular body 30 is completed, the first reflective member 20 is spaced apart from the vertical upper portion of the LED module 40 It will be arranged.

As described above, the first reflecting member 20 of the present invention is configured to have the following shape along with structural features disposed on the vertical upper portion of the LED module 40, so that the front and side directions as well as the rear range as necessary Visibility can also be extended, enabling up to 360 ° omnidirectional optical display.

The first reflecting member 20 according to FIG. 7 is configured to allow the LED light incident on the first reflecting member 20 to spread out at 360 ° with respect to the optical axis. Referring to FIGS. 7 and 8, the horizontal cross-sectional area becomes narrower from the top to the bottom, and is configured as a cone having a symmetrical structure before, after, left, and right about the central axis of the cone. The central axis (that is, vertex) of the conical first reflective member 20 having a symmetrical structure was configured to be positioned on the optical axis.

In addition, the conical first reflecting member 20 is made of a medium that totally reflects incident light, and the maximum transverse cross-sectional area of the conical first reflecting member is configured to be at least greater than the width of the LED light.

Referring to FIG. 9, an operation in which the LED light is diffused omnidirectionally through the first conical reflective member 20 will be described in detail.

The first reflective member 20 having a conical shape is spaced apart from the LED element 41 by a predetermined distance so as to face the vertical upper portion thereof, and the central axis thereof is disposed to coincide with the optical axis. By the shape and arrangement of the first reflecting member 20 as described above, the straight light emitted from the LED element 41 to the vertical upper part is incident on the first reflecting member 20 and then undergoes a reflecting process. It is evenly spread in the 360 ° forward direction, including the front L1, rear L4, and side surfaces L2 and L3, based on the central axis of the reflective member 20, and then radiates through the transparent tube 30 to the outside. .

Therefore, if the LED indicator 170 of the present invention is installed in the bus platform, the light display is implemented in all directions based on the bus platform, so the bus driver driving toward the platform accurately recognizes the presence of passengers at all distances in all directions. You can do it. That is, it is possible to implement an optical display device having greatly increased visibility while using only one LED element.

The LED module 40 of the present invention is composed of the LED element 41, the circuit board and the housing 42.

The LED element 41 is a light source for displaying light, and the LED light emitted from the element 41 has a linearity in the form of a point light source having a relatively small light emitting area. Any one of various wavelength bands such as red light, green light and blue light can be selected and adopted. The LED element 41 is provided so that the optical path of the point light source emitted from the element 41 is directed in one direction (preferably an upper direction perpendicular to the ground).

The circuit pattern (for example, copper wiring) for electrical connection of the LED element 41 is printed on the upper surface of the circuit board, and the LED element 41 is connected to the wiring to receive power from the outside. For reference, according to the LED indicator light 170 of the present invention, since only one LED element 41 can fully achieve the omnidirectional light display function, only one LED chip is mounted on the circuit board.

The housing 42 corresponds to a member for enclosing the LED element 41 and the circuit board inside and protecting them from an external environment (eg, water). However, the LED element 41 and the circuit board are disposed in a state accommodated inside the housing 42, but at least the light output area of the LED element 41 is exposed to the outside of the housing 42 so as to be in one direction (preferably perpendicular to the ground). One upward direction).

Body 50 of the present invention is a member that is coupled to the lower portion of the transparent tube 30 to support the transparent tube 30, the electric device including a voltage regulator is included therein. The electrical device may include a controller for controlling a lighting method (for example, repeating the flashing of the LED light and performing light display, etc.) during the lighting operation of the LED element.

10 (a) and (b) are views showing a first reflecting member and a 1-1 reflecting member respectively provided in the tubular cap of the present invention, and reference numeral “K1” in FIG. 10 denotes a transparent tubular body 30. Refers to the central axis of the LED light traveling path emitted from the LED module 40 installed in the lower portion of the straight.

First, the first reflecting member 20 configured in the form of FIG. 10 (a) has a shape and a shape as described and illustrated in the embodiments of FIGS. 7 and 8, and the horizontal cross-sectional area becomes narrower from the top to the bottom. The central axis of the first reflecting member 20 having a symmetrical structure of front, rear, left, and right symmetry with respect to the central axis, wherein the central axis of the conical first reflective member 20 has an optical axis K1. And is positioned on the bed. As described above, the first reflective member 20 having the shape of FIG. 10 (a) is suitable for use where a light display in a 360 ° direction including front, rear, and lateral directions is required.

However, it may be inefficient to install a display device that implements an optical display on the rear side as shown in FIG. 10 (a) where a light display is required only for the front and side directions. In this case, if the light directed to the rear can be sent to the front and the side, the luminance can be further increased, thereby improving the optical display performance. In this case, the user removes the tubular cap to which the first reflecting member 20 of FIG. 10 (a) is coupled and then refers to the first reflecting member (hereinafter, referred to as 1-1 reflecting member 25) of FIG. 10 (b). By simply replacing the combined cap with a tube) can achieve the above object.

The first-first reflecting member 25 of the present invention expands the emission angle of the LED light and thus expands visibility, and has a suitable shape when most of the light is directed toward the front and side directions. The first-first reflecting member 25 is formed in a conical shape whose horizontal cross-sectional area becomes narrower from the top to the bottom, and is formed to include an asymmetrical shape based on the central axis of the conical shape. That is, the left and right sides are symmetrical shapes with respect to the central axis K1 of the conical shape, but are configured to form an asymmetrical shape before and after.

Unlike the first reflecting member 20 of FIG. 10 (a), wherein the vertex of the cone is configured to coincide with the optical axis, the 1-1 reflecting member 25 of FIG. 10 (b) has a vertex of the cone and the optical axis K1. It does not correspond and is comprised so that it may shift | deviate from the optical axis K1. Accordingly, most of the LED light incident on the first-first reflecting member 25 along the optical axis may be reflected and radiated in the front and side directions.

As described above, the LED indicator light 170 of the present invention is provided with a tubular cap having various types of conical reflective members and configured such that the tubular cap can be detachably coupled to the transparent tubing, thereby providing various structures and shapes of a bus platform. According to this, simply replacing the appropriate cap can implement the optimal light display range in the installation environment. That is, the visibility can be extended through the cone-shaped first reflecting member 20 facing the LED element 41, and further, it is possible to flexibly respond to maximize the light efficiency according to the installation environment.

The second reflecting member 60 provided in the LED module 40 does not emit to the outside after being reflected by the first reflecting member 20 and serves to reflect back the reflected light incident to the LED module 40. As such, the second reflecting member 60 may further improve the light efficiency (that is, luminance) of the device by emitting the reflected light remaining inside the transparent tube to the outside without leaving.

 The second reflective member 60 according to the preferred embodiment of Figure 11 is made of a disk shape, the center of the hole at least the size through which the LED element 41 can be exposed to the outside, the upper surface is inclined inwardly to be recessed overall It is composed of a disk shape having a fine shape. In addition, the height of the second reflecting member 60 should be formed so as not to interfere with the path of the light emitted from the LED element 41.

Referring to FIG. 12, a process in which the second reflecting member 60 emits residual reflected light to the outside, most of the LED light emitted from the LED element 41 is scattered in all directions by the first reflecting member 20, and the outside Although emitted to the light, some of the reflected light is incident on the LED module 40 side due to diffuse reflection or the like. As such, the reflected light incident on the LED module 40 without proceeding to the outside is reflected back by the inward gradient surface of the second reflecting member 60 provided on the LED module 40 to be emitted to the outside, thereby The visibility can be further improved.
