In addition, Figure 3 is a block diagram of a system for preventing unauthorized crossing according to the present invention. In addition, Figure 4 shows another embodiment of the system for preventing unauthorized crossing according to the present invention.

The system for preventing unauthorized crossing according to the present invention includes a main body 100, a display 200, a detection unit 300, a control unit 400, and a power supply unit 500.

The present invention can be implemented in the form of indicator lights or guidance lights for pedestrians waiting for a signal at the pedestrian crossing 10, and is for the purpose of reducing the incidence of unauthorized crossing, and a crosswalk prevention system according to the present invention for pedestrians waiting for a signal It has the purpose of preventing confusion in waiting for a signal or crossing the crosswalk 10 according to the signal by generating a rule by using. The composition and effects related to this should be described.

The main body 100 may have a shape having a predetermined thickness and may include a form of a guide lamp, and is installed on the bottom surface of the sidewalk toward the crosswalk 10. In addition, the size and thickness of the body portion 100 shown in the drawings are arbitrarily shown for convenience of description, and are not limited to those shown in the drawings.

In addition, the material of the main body 100 is implemented with reinforced plastic having excellent thermal properties, mechanical properties, and optical properties, and is installed on the floor of the sidewalk used by many people, so that it can respond to friction and the force that people step on. .

The display unit 200 is installed on the body unit 100, and a plurality of images representing the shape of arrows are sequentially displayed adjacent to each other in the width direction. At this time, the plurality of images of the display unit 200 installed on the main body 100 are not limited to the shape of an arrow, but may be variously expressed as images for recognizing danger to pedestrians waiting for a signal. Not limited.

The display unit 200 includes a first display unit 210, a second display unit 220, a third display unit 230, and a fourth display unit 240 in the same shape as an arrow.

As shown in FIG. 1, the second display unit 220 is positioned vertically adjacent to the first display unit 210, and in the same manner, the third display unit 230 and the fourth display unit 240 are provided with the first display unit ( 210) and the second display unit 220 are disposed adjacent to each other in the width direction on the same line.

In this case, the display unit 200 is characterized in that the color density is increased in the order of the first display unit 210 and the fourth display unit 240 in the endoscope. Due to this, there is an advantage of being able to give directions to those waiting for a signal.

In addition, it is preferable that the display unit 200 includes an LED. LED is a known LED module, a configuration in which a plurality of LED elements are mounted in a certain arrangement on a circuit board, and may include a plurality of light emitting diodes (LEDs), driven by a control unit 400 to be described later do. In addition, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and 3 It may include at least one of 3D displays. Implementing the display unit 200 as a three-dimensional display is another embodiment of the system for preventing unauthorized crossing according to the present invention, and the system and effects will be described later.

The display unit 200 including such a display shape may have different colors depending on the situation, and may be sequentially generated.

The effect will be described in detail in the following.

First, as shown in Figure 2, when arranged toward the crosswalk 20, among the pedestrians waiting for a signal, light is generated to the pedestrians who want to cross the crosswalk 20 past the main body 100 I can.

For example, the display unit 200 may give a warning in the form of blinking repeatedly lit and blinking a red light to a pedestrian who wants to cross the body unit 100 without permission. This may be driven by the control unit 400, and the light of the display unit 200 may be provided not limited to a red color, but limited to a color capable of giving a warning.

Accordingly, by generating a warning to the pedestrian who wants to cross the crossing through the display unit 200, it is possible to prevent the behavior of crossing without permission, and the effect of preventing an accident rate due to the crossing occurs.

Second, in general, the crosswalk 10 is located at an intersection with a first crosswalk 11 and a second crosswalk 12 as shown in FIG. 2 and is installed in the form of a road sign on the road. There is a problem that confusion is caused when crossing the crosswalk 10 by waiting for the signal and watching the signal during times when many people use the first crosswalk 11 and the second crosswalk 12 during the commute and commute period. have.

Accordingly, the display unit 200 of the system for preventing unauthorized crossing according to the present invention detects a pedestrian as a number of times by a detection unit 300 to be described later, and turns on at a point where a relatively large amount of waiting is generated to generate a rule to thereby generate a crosswalk 10 There is an effect that can reduce confusion in crossing.

That is, the main body parts 100A, 100B, 100C, and 100D are arranged side by side at a predetermined distance in the longitudinal direction toward the crosswalk 10, and the main body part is relatively more than the main body parts 100A, 100B by detecting pedestrians. If there are many locations in (100C, 100D), it is possible to generate a rule that enables the display unit 200 of the main body 100C, 100D to be driven to cross the road using the second crosswalk 12. .

In addition, the main body parts 100a, 100b, 100c, and 100d are arranged side by side at a predetermined interval in the longitudinal direction toward the crosswalk 10, and the main body parts 100a, 100b are more than the main body parts 100c, 100d. When a relatively large number of pedestrians is detected, a rule that enables the display unit 200 of the main body parts 100a and 100b to be driven to cross the road using the first crosswalk 11 may be generated.

Therefore, people who use the crosswalk 10 can be visually transmitted first through each of the main body 100 and the display unit 200, so that the inconvenience caused by colliding with each other while crossing the road after waiting for a signal or crowding of pedestrians There is an advantage that can eliminate the box.

As above, it is possible to drive the display unit 200 according to the situation, including a method in which the first display unit 210 is sequentially turned on toward the second display unit 240 so that pedestrians waiting for the signal can be momentarily concentrated. You can maximize the above effect by increasing the value.

Finally, there is a problem in that it is difficult for the driver to check the pedestrian crossing 10 and the pedestrians waiting for a signal to use it in dark times such as at night. The main body 100 and the display unit of the system for preventing unauthorized crossing according to the present invention Due to (200), it is possible to secure the driver's field of view, thereby increasing visibility, thereby preventing accidents and improving stability.

That is, there is a problem that it is more difficult for the driver to identify pedestrians using the crosswalk 10 in the case of a dark night. However, due to the display unit 200 installed in each main unit 100, the driver's visibility is increased because it can be visually recognized, thereby reducing the accident rate in the crosswalk 10 in a dark time.

Such driving is driven through the sensing unit 300 (see FIG. 3).

The detection unit 300 is provided with sensors installed in the main body 100 and positioned relatively close to the crosswalk 10 to recognize pedestrians going toward the crosswalk. For example, the sensing unit 300 may include a thermal imaging camera, an infrared camera, an ultrasonic sensor, and the like, and may detect a pedestrian who attempts to cross a road without permission. For example, the detection unit 300 may detect the number of times a pedestrian entering the roadway using a thermal imaging camera or an infrared camera.

In addition, the detection unit 300 may be connected to a pedestrian traffic light or a vehicle traffic light. Accordingly, when the signal of the pedestrian traffic light is red and the signal of the vehicle signal is blue, the detection unit 300 may identify the pedestrian and detect whether or not to cross the vehicle without permission.

The control unit 400 generally controls the overall operation of the system for preventing unauthorized crosswalks according to the present invention, and is preferably installed inside the main body 100 or near a traffic light and a crosswalk 10 along with a support. In addition, the control unit 400 is a known control unit that instructs the operation by receiving and supplying signals to drive the respective display unit 200 and the sensing unit 300, and controls the components. do. Since this can be stored and executed by a processor and an algorithm, which are known control technologies, a detailed description will be omitted.

In addition, the controller 400 may be provided with a speaker to output sound or voice. It is for generating an output related to visual, auditory or tactile sense, and may include an audio output module and a projector module, not limited to a speaker.

The control unit 400 as described above may receive signals from each of the sensing units 300, and may combine and transmit a signal for driving. In addition, in the case of controlling each display unit 200 to light up in a red color, a voice is output from the speaker at the same time, so that pedestrians who want to crosswalk are not only visually but also audible to recognize the warning to prevent unauthorized actions. There is an effect that can regulate the behavior of pedestrians who do.

In addition, the control unit 400 may have a time table to set a time zone in which pedestrians mainly use the crosswalk, and stop driving during a time when the use is less, thereby reducing power consumption.

In other words, it is possible to have a time table in which the commute, commute time, and commute time, which are the times mainly used by pedestrians, can be provided, and the advantage of increasing the efficiency by arbitrarily stopping driving during times when the use of pedestrians is relatively low. have.

Although not shown in the drawing, the power supply unit 500 receives external power and internal power under the control of the control unit 400 to supply power required for operation of each component. The various embodiments described herein may be implemented in a recording medium that can be read by a computer or a similar device using, for example, software, hardware, or a combination thereof.

According to the hardware implementation, for example, application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmed gate arrays (FPGAs), processors ), controllers, micro-controllers, microprocessors, and other electrical units for performing other functions.

Hereinafter, another embodiment of the system for preventing unauthorized crossing according to the present invention will be described with reference to FIG. 4.

The display unit 200 of the system for preventing unauthorized crossing according to the present invention may be implemented as a 3D display or a 3D hologram as described above to exhibit a three-dimensional shape.

Here, in the digital holographic display, an image recorded in real time through the display may be implemented as a 3D stereoscopic image by using a light source having coherence. At this time, the coherence means the property of long, threadlike light. Therefore, since fluorescent lamps, incandescent lamps, LEDs, etc. do not have such interference, a three-dimensional shape cannot be formed in such a way that a short piece of thread-like rays spread out in all directions. Such a hologram can form an image three-dimensionally through the principle that rays meet and interfere with each other. A bright light dot is created at the place where the rays interfere constructively, and if you create a desired image pattern by tens of thousands of these dots, a three-dimensional image floating in space is created. It can be seen that the light points made by such interference act as a pixel in the display.

In addition, the display unit 200 may be implemented as a projector module, and the projector module may be divided into a cathode ray tube (CRT) module, an LCD module, and a digital light processing (DLP) module, depending on the type of device of the display means. In particular, the DLP module may be advantageous for miniaturization of a projector module by expanding and projecting an image generated by reflecting light generated from a light source onto a digital micromirror device (DMD) chip. Specifically, the projector module is not shown in the drawing, but a light source that generates light for outputting an image to the outside, an image generating means for generating an image to be output to the outside using light generated by the light source, and a certain focus of the image It may include a lens for enlarged output from a distance to the outside. In addition, the projector module may include a device capable of adjusting the direction of image projection by mechanically moving the lens or the entire module.

In such a digital holographic display, the display unit 200 in the system for preventing unauthorized crossing according to the present invention is implemented in the shape of a dog, for example, to induce a pedestrian to retreat by a dog biting a shoe to prevent unauthorized crossing. There is an effect that can be done. In addition, since it can be used for various commercial advertisements and marketing activities, promotions for generating profits can be effectively carried out within a short time, thereby increasing the utility of the unauthorized crosswalk prevention system according to the present invention.

In addition, it is preferable that a coating layer is formed on the body part 100.

The coating layer (not shown) is coated using a coating composition, and the coating layer using the coating composition may exhibit an antistatic effect and a waterproof effect. Specifically, the coating layer prevents adhesion of dust and the like, and at the same time, due to the water-repellent effect, an excellent waterproof effect may be exhibited. More specifically, the coating composition of the present invention comprises a siloxane-based compound represented by the following Chemical Formula 1; It may include a conductive filler and carbon nanotubes.

[Formula 1]

Where n is an integer from 1 to 100.

After forming the coating layer using the coating composition of the present invention, the contact angle measurement result was found to be 130 to 140 degrees, and as can be seen in the range of the contact angle, it will be said that the waterproof effect is exhibited by the coating layer.

The conductive filler may be selected from the group consisting of silica, alumina, and mixtures thereof. The particle diameter of the conductive filler is 70 to 100 μm, but is not limited to the above example. The conductive filler may exhibit electrical conductivity in the antistatic layer.

The carbon nanotubes are contained in a small amount, so that the antistatic effect in the antistatic layer can be continuously maintained. Considering that the carbon nanotube is an expensive conductive filler, it is contained in a small amount in the coating layer in the present invention, so that it can maintain a continuous antistatic effect.

More specifically, the coating layer of the present invention comprises a siloxane-based compound represented by Chemical Formula 1; By including a conductive filler and carbon nanotubes, it may exhibit an antistatic effect. The siloxane-based compound is divided into a hydrophilic portion and a hydrophobic portion. The hydrophilic moiety is capable of hydrogen bonding with water molecules by means of an oxygen atom containing an unshared electron pair. On the other hand, as a hydrophobic group including an alkyl group or an aryl group is additionally included, a hydrophobic group acts on the opposite portion of the hydrophilic portion. Therefore, the hydrophilic portion is positioned as the surface of the antistatic layer, and the hydrophobic portion is positioned oppositely, thereby exhibiting a semi-permanent antistatic effect.

In order to form the coating layer, the coating composition is more specifically a siloxane-based compound represented by Formula 1; It can be prepared by mixing a conductive filler, a carbon nanotube, and an organic solvent.

The organic solvent may be selected from the group consisting of ethanol, methanol, butanol, hexane, propane, toluene, phenol, and mixtures thereof.

The coating composition may include 40 to 60 parts by weight of the siloxane compound represented by Formula 1, 20 to 40 parts by weight of a conductive filler, and 5 to 15 parts by weight of carbon nanotubes, based on 100 parts by weight of the organic solvent. In the case of the above range, the synergistic effect of antistatic and waterproof effects due to the interaction of the respective constituents is exhibited to a degree of critical significance, and if it is out of the above range, the synergistic effect is rapidly reduced or almost no.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and if the viscosity is less than 1500 cP, there is a problem that it flows down during coating on one side of the substrate layer, making it difficult to form a coating layer, and if it exceeds 1800 cP, it is uniform There is a problem that the formation of the coating layer is not easy.

[Production Example 1: Preparation of coating layer]

2. Preparation of coating layer

After applying the coating composition of DX1 to DX5 on one side of the substrate layer, it was cured to form a coating layer. In order to test antistatic and uniform coating layer formation, an experiment was conducted using polycarbonate as a base layer instead of a solar panel.

[Experimental Example 1: Antistatic Effect Experiment]

1. Viscosity measurement

Before forming the antistatic layer on one side of the polycarbonate base layer, the viscosity of the antistatic composition was measured. The viscosity was measured using a rheometer (Rheometer, Compac-100, Sun Sci. Co., Japan). The viscosity measurement results are shown in Table 2 below.

2. Surface electrical resistance measurement

For the protective layer in which the antistatic layer of TX1 to TX5 was formed on one side of the polycarbonate substrate, surface electrical resistance was measured using a Resistance Meter SIMCO resistor ST-4 (23° C., 50% relative humidity).

As a comparative example, the surface electrical resistance of the polycarbonate substrate on which the antistatic layer was not formed was also measured.

4.4×107 to 2.1×108
6.5×107 to 4.5×108
5.8×108 to 7.8×108

According to Table 3, compared to the comparative example in which the antistatic layer was not formed, since the surface electrical resistance of TX 1 to TX5 was low, it was confirmed that the electrical conductivity was excellent, and thus an excellent antistatic effect was exhibited.

3. Evaluation of surface appearance

Due to the difference in viscosity of the antistatic composition, after preparing the coating layer, sensory evaluation was conducted as to whether a uniform surface was formed. Evaluation was conducted as to whether or not a uniform coating layer was formed, and evaluation was conducted according to the following criteria.

When forming the coating layer, when it is less than a certain viscosity, flow occurs on the surface of the polycarbonate, and there are many cases where it is difficult to form a uniform coating layer after the curing process. Accordingly, a problem of lowering the production yield may occur. In addition, even when the viscosity is too high, it was difficult to uniformly apply the composition, and thus it was impossible to form a uniform coating layer.

4. Measurement of water repellency angle

After forming the coating layer on the substrate layer, the results of measuring the water repellency are shown in Table 5 below.

Advance contact angle (°) Stop contact angle (°) Reverse contact angle (°) TX1 117.±12.9 112.1±4.1 <10 TX2 132.4±1.5 131.5±2.7 141.7±3.4 TX3 138.9±3.0 138.9±2.7 139.8±3.7 TX4 136.9±2.0 135.6±2.6 140.4±3.4 TX5 116.9±0.7 115.4±3.0 <10

As shown in Table 5, after forming the coating layer using the coating composition of TX1 to TX5, the contact angle was measured and the result was confirmed.

TX1 and TX5 were measured to have a reverse contact angle of less than 10 degrees. That is, when it is out of the optimum range for preparing the coating composition, it was confirmed that a phenomenon in which water droplets are pinned occurs. On the other hand, it was confirmed that the pinning phenomenon did not occur in TX2 to 4, and it was confirmed that an excellent waterproof effect could be exhibited.

Therefore, since the coating layer having the above properties is formed along the outer surface of the main body 100, an antistatic effect and a waterproof effect are generated, and thus the lifespan is increased in an external environment where rust or decay occurs.
