Hereinafter, the structure of the traffic light installation type non-contact switch system of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the installation of a body according to an embodiment of the present invention. The present invention is installed on various pillar structures P installed on a road and is configured to be operated by a pedestrian, and can be used for various purposes. In the present invention, in Figure 1 attached along with a pedestrian signal conversion switch as an embodiment as a universal application target, the body 100 of the present invention is installed in the column structure P of the traffic light.

The body 100 is a case containing a switch system configuration described later, and is made of a waterproof structure with a transparent cover 101 formed on the front surface to prevent moisture from penetrating into the inside as it is exposed to the outside air and damaging the electronic configuration, It can be installed on the pillar structure P in various ways, but it can be installed easily and firmly through a steel band for a conventional pedestrian signal switch.

These pedestrian signal switches are used in conjunction with a traffic signal system (S) that controls traffic lights to change the vehicle stop signal and pedestrian crossing signal by pressing the pedestrian before crossing the crosswalk.

Figure 2 is a front view showing the structure of a body according to an embodiment of the present invention, Figure 3 is a side cross-sectional view showing the structure of a body according to an embodiment of the present invention, Figure 4 is a configuration and connection relationship according to an embodiment of the present invention As a block diagram showing, the present invention is a display module 110, a sensing module 120, a sound output module 130, a control module 160 and a power supply unit as main components embedded in the body 100 ( 170), an illuminance sensor 140 and a pressure sensor 150 are provided for operational efficiency and convenience.

The display module 110 is installed inside the transparent cover 101 and outputs an image signal toward the front, and may be composed of a small LED panel. Since this is for improving the visibility of the switch including operation status rather than transmitting any image information, a relatively small and low resolution panel can be applied, and if a sufficient installation space is secured, the size and resolution can be increased to provide a variety of image information. delivery is also possible.

In addition, it is composed of a screen without a touch function according to the purpose of the present invention called a non-contact switch, and as mentioned above, it is covered with a transparent cover 101 to prevent contamination and damage due to foreign substances while securing waterproof performance.

The detection module 120 is installed on the front rim of the body and is configured to detect the approach of a hand. As mentioned above, based on non-contact operation, proximity for detecting a pedestrian's hand approaching within 5 cm It can be configured through a radar sensor. That is, a transmitter 121 for transmitting radio waves and a receiver 122 for receiving radio waves reflected from the pedestrian's hand are configured to measure the shape and distance of the hand through the reflection time of the transmitted radio waves. The activation of the switch operation is made even in the non-contact state.

The sound output module 130 is installed on one side of the body as a speaker and outputs a sound signal. That is, it is built into and protected in the body 100 so that the sound signal can be smoothly output to the outside through the through hole that passes through the outside of the body, and the through hole is provided to the lower side of the body so that rainwater does not flow through the through hole in case of rain. However, it is preferable to have a thin film or an inflow blocking structure capable of passing through the acoustic signal and preventing the inflow of moisture.

The control module 160 is a component for receiving power and controlling the display module 110, the detection module 120, and the sound output module 130, and the main detailed components include a storage unit 161 and a determination unit. 162, an interlocking unit 163, and an image control unit 164.

The storage unit 161 is a memory and stores video signals related to operations. Basically, an image that can intuitively know that it is a switch, an image that can distinguish an active state from an inactive state as described later, and a simple logo for promotion can be stored and used if necessary. At this time, reflecting the purpose of the present invention, it is preferable to output phrases such as non-contact and untact and related images so that pedestrians can easily recognize that the switch operates in a non-contact manner, and examples of other specific images will be described later.

The determination unit 162 is a component that generates an operation signal by analyzing the detection result of the detection module. In other words, as mentioned above, when the pedestrian's hand approaches the center of the body within 5 cm in the disabled state, it is recognized as trying to press the switch. There is a need. To this end, the determination unit 162 determines the intention to operate the switch through maintaining the proximity state for a set time, for example, 1 to 2 seconds, or the user's hand who wants to press the switch depending on the type of the detection module 120. After analyzing the detection result by using the method of detecting the shape, an operation signal for activation can be generated when the intention to press the switch is determined, and an operation signal for maintaining the inactive state due to an incorrect operation can be generated at other times.

In addition, if necessary, the switch of the present invention can be used as an emergency reporting means for crime prevention rather than for pedestrian signal control. An operation signal may be generated in response to recognizing a set operation differentiated from the above.

The interlocking unit 163 collects signal information in association with an adjacent traffic signal system (S), generates a request signal corresponding to the operation signal, and applies it to the traffic signal system. That is, by reflecting the signal information collected according to the operation signal for activation, a request signal is generated and applied to the traffic signal system so that the pedestrian traffic light changes from red to green, and the corresponding vehicle traffic signal changes from green to yellow to red. will do

At this time, the traffic signal system (S) changes the signal after a set time in consideration of the basically set time and the elapsed time after the previous pedestrian signal change.

The image controller 164 outputs a video signal corresponding to the operation signal and signal information to the display module 110 . Basically, the image in the inactive state is changed to the image indicative of activation so that the pedestrian can easily check whether or not the motion is normally activated.

To this end, the video signals stored in the storage unit 161 are stored separately according to the activation and inactivation states, and the video control unit 164 visualizes the change in signal waiting time in conjunction with the timer and the signal information. It is preferable to be configured to output.

Figure 5 is a conceptual diagram showing the output of a video signal according to an embodiment of the present invention. Figure 5 (a) shows an image intuitively showing that a pedestrian is a switch, and in a normally inactive state of the switch, the power is turned off. It is possible to distinguish video signals according to activation and inactivation states in such a way that the red color is maintained and the color is changed to blue when activation is performed.

In addition, in the case of a conventional pedestrian signal switch, it is configured in the form of a simple push button, so even if a pedestrian presses it, the signal does not change immediately, but as the signal changes after a set time, it was not possible to confirm whether the signal conversion function was activated by pressing the button normally, As a result, there was a problem such as pressing the switch several times for confirmation.

In response to this, attached FIG. 2 shows an image associated with a timer so that pedestrians can easily know the remaining time by reflecting the waiting time until the aforementioned signal change, which gives pedestrians psychological stability and relaxation according to preparation for signal change. can

Attached Figure 5 (b) shows a state in which the symbol of the current competent local government is output. Simple advertisements can be output as images that can be output in a deactivated state, but as the traffic signal system becomes the jurisdiction of the local government, an image that can be used for publicizing the image of the local government is exemplified, and FIG. It can be configured to promote the convenience of pedestrians by outputting the current time in .

As such, the image control unit 164 may be configured so that the display module converts and outputs the current time, a related local government symbol, and a switch display according to a set time in an inactive state.

The power supply unit 170 is a component for supplying power for the operation of the series of components mentioned above, and may be configured through a battery that can be charged and discharged, but is basically linked to the traffic signal system. It is desirable to have it supplied with power. That is, in the case of the traffic signal system, not only is power supplied at all times except in an emergency situation, but if power is not supplied to the traffic signal system, even if power is supplied to the control module of the present invention through a battery, the function can be smoothly performed. because there is no

In addition, as the visibility of the display module 110 may vary depending on weather conditions including daytime and nighttime, the control module is installed in response to an accident in which the illuminance sensor 140 for measuring the brightness of the surroundings is installed on the body. It may further include a control unit 165 that adjusts the brightness of the display module by reflecting the time and the measured ambient brightness.

That is, when the surroundings are bright, such as during the day, the brightness of the display module 110 must also be bright to ensure visibility. Therefore, the control unit 165 adjusts the brightness of the display module 110 by reflecting the ambient brightness measured through the illuminance sensor 140, since it is possible to operate efficiently without increasing the brightness unnecessarily.

6 is a conceptual diagram showing another image signal output according to another embodiment of the present invention. As mentioned above, it can be used for crime prevention and emergency reporting purposes in addition to pedestrian signal change purposes to have various crime prevention effects. In this case, since there is a high possibility of pressing the switch in an emergency rather than approaching the hand, a pressure sensor 150 is installed inside the body 100 to detect the pressure applied from the front, and in response to this, the control module When the set time pressure is sensed through the pressure sensor 150, a warning signal is displayed through the display module 110 and the sound output module 130, and then, when the set time pressure continues, an emergency that transmits report information to a set corresponding institution. A contact unit 166 is further included.

This is to stop the criminal progress by breaking the criminal will before the accident reception and dispatch, and to prevent false reports due to malfunctions. A visual alarm signal as shown in FIG. 6 is output through the display module 110, and at the same time, an alarm sound indicating that a crime prevention siren or a report and dispatch is made is output through the sound output module 130. This not only significantly lowers the criminal will, but also induces the release of the neoclassical pressure if the action is due to unintentional manipulation.

Afterwards, when the second set time pressure continues, the emergency contact unit 166 transmits and reports report information including the location to the set response agency, police station, police station, crime prevention post, etc. using the emergency report function of the commercial mobile communication network. Receipts and countermeasures are made.

The rights of the present invention are defined by what is described in the claims, not limited to the embodiments described above, and that those skilled in the art can make various modifications and adaptations within the scope of rights described in the claims. It is self-evident.
