It is provided to fully convey the scope of the invention to those skilled in the art, and the present invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, the present invention will be described with reference to the drawings for describing a system for controlling power supplied to an electric display board according to whether an object is detected by embodiments of the present invention.

1 is a block diagram of a system for controlling power supplied to an electric display board according to whether an object is detected according to an embodiment of the present invention.

When the object detecting unit 10 detects the object C1, the system 1 for controlling the power supplied to the display board according to the object detection according to an embodiment of the present invention supplies power to the display module 520. When the object detecting unit 10 does not detect the object C1, power may not be supplied to the display module 520.

The present invention selectively supplies power to the display module 520 according to whether the object detecting unit 10 detects the object C1, and prevents the display module from consuming electricity in an unnecessary situation. Can be driven.

The system 1 for controlling the power supplied to the display board according to whether the object is detected is the object detecting unit 10, the object detecting signal processing unit 20, the object detecting unit 30, the trigger signal generating unit 40, and the display board. The unit 50 is included as a component.

2 to 5, the components of the system 1 and the operation of the components for controlling the power supplied to the display board according to whether the object is detected will be described in detail.

FIG. 2 is a block diagram of the electronic display panel of FIG. 1, and FIG. 3 is an internal configuration diagram of the electronic display panel of FIG. 1. 4 is a state diagram of a system for controlling power supplied to an electric display board according to whether an object is detected according to an embodiment of the present invention. 5 is a diagram illustrating the display module of FIG. 1.

The object detecting unit 10 may be installed in a structure such as a support to photograph or detect a predetermined area in which a vehicle, a person, and an animal move. The object detecting unit 10 may be a closed circuit television (CCTV) or a loop detector. The object detecting unit 10 may be formed of a closed-circuit television to generate an image data signal when capturing a predetermined region. The object detecting unit 10 may transmit an image data signal to the object detecting signal processing unit 20 connected by wire or wirelessly. On the other hand, when the object detecting unit 10 is formed as a loop sensor, the object detecting unit 10 is installed on the floor surface on which the set object moves, and the main object using the change in the loop coil inductance and the change in the oscillation frequency resulting therefrom. Can be detected. In this case, an object that makes the oscillation frequency of the object detecting unit 10 low may be detected as a main object.

The object detection signal processing unit 20 transmits the image data signal received from the object detection unit 10 to the object detection unit 30. The object detection signal processor 20 may include an image packet receiving module and a decoding module. Accordingly, the object detection signal processing unit 20 may sequentially receive image data signals from an external network through the object detection unit 10 or the like over time. And a detection signal can be received. The object detection signal processor 20 may sequentially process the received image data signal and the detection signal to convert a specific image data signal into object data.

The object detecting unit 30 is a device for detecting a setting object. For example, after receiving the data signal sequentially from the object detection signal processing unit 20, and detects the setting object according to the change of the oscillation frequency according to whether the operation module or the setting object to detect the setting object from the data signal. It may be formed of a roof coil or the like.

The object detecting unit 30 may detect the object C1 of the data signal as the main object when the matching value between the setting object and the object is greater than or equal to the reference value in preparation for the setting object and the object. In addition, the object detector 30 may detect whether the load is properly loaded or incorrectly loaded. For example, the object detecting unit 30 may divide the vehicle in the data signal D into a plurality of parts, match the part of the setting object, and detect whether the vehicle is the setting object. In addition, the object detector 30 may detect unique information of the main object. In one example, the object detection unit 30 may detect the number described on the license plate of the vehicle.

The object detector 30 detects the main object in this manner and can accurately detect the main object from the image data signal D. In addition, the object detector 30 may further include an infrared transmitter and an infrared receiver, and the calculation module may calculate a distance of the detected main object by calculating a time when the light output from the infrared transmitter is reflected through the main object.

The object detector 30 may transmit different signals to the trigger signal generator 40 according to whether the main object is detected. In this case, the object detector 30 may transmit different detection signals to the trigger signal generator 40 according to the type of the main object. In addition, when the main object is set as a vehicle, the object detecting unit 30 generates a detection signal and detects whether there is a cover covering the load loaded on the vehicle or whether the load is out of the outside of the vehicle. Can be detected. For example, the object detecting unit 30 detects the load E loaded on the vehicle, and when the protrusion load E1 of one of the normal loads E2 protrudes over the preset protrusion distance SP, the load is loaded. It may generate a bad signal. In addition, the generated loading failure signal may be transmitted to the trigger signal generator 40. In addition, the object detecting unit 30 may transmit the unique number of the main object, that is, the number written on the license plate of the vehicle, to the display module 520 when the loading failure signal is generated.

The trigger signal generator 40 may generate different trigger signals according to the detection signal transmitted from the object detector 30. For example, the trigger signal generator 40 may generate a first trigger signal when a detection signal corresponding to a signal in which the main object is not detected by the object detector 30 is transmitted. The trigger signal generator 40 may generate a second trigger signal when the detection signal corresponding to the signal detected by the object detector 30 is transmitted. In addition, the trigger signal generation unit 40 may transmit different detection signals according to the type of the main object in the object detection unit 30, the second trigger signal corresponding to the detection signal according to the type of the second a trigger signal and The second b trigger signal may be generated. In addition, when the loading failure signal is received, the third trigger signal may be generated. Here, the first trigger signal may be a signal for preventing the electric sign 50 to operate, and the second trigger signal may be a signal for operating the electric sign 50. The third trigger signal may be a signal generated by the trigger signal generator 40 when the load is projected by the object detector 30 more than a preset protrusion distance while operating the electric sign 50.

When the electronic sign unit 50 receives the first trigger signal through the switch module 540, the electric current path is formed as an open circuit so that power is not applied to the memory module 510 and the display module 520. Do not.

On the other hand, when the second trigger signal, the second a trigger signal, the second b trigger signal, and the third trigger signal are received, the current path is formed as a closed circuit to supply power to the memory module 510 and the display module 520. To be authorized. In this case, the electronic sign unit 50 has a first end of the switch module 540 connected to the trigger signal generator 40, a second end connected to a positive pole of the power module, and a third end of the switch module 540. The display module 520 and the communication module 550 may be connected to the cathode of the power module.

When the electronic sign unit 50 receives the second trigger signal, the second a trigger signal, the second b trigger signal, and the third trigger signal from the trigger signal generator 40 through this structure, it is output from the power module 530. Electricity may be applied to the memory module 510, the display module 520, and the communication module 550.

The memory module 510 stores a plurality of information messages therein and outputs different information messages according to the magnitude of the current transmitted through the switch module 540 and transmits them to the display module 520. Here, the switch module 540 is formed of a PNP-type transistor, in response to the signal transmitted from the trigger signal generation unit 40, it can output a current of various magnitudes flowing in the direction from the second end to the third end. .

Through this, the memory module 510 operates the switch module 540 by the second trigger signal and outputs the first information message when the first current is applied, and operates by the second a trigger signal to apply the second a current. When the 2b information message is output, the second b information message may be output when the second b current is applied. When the third current is applied to the third trigger signal, the third information message may be output.

The display module 520 may output the information message transmitted from the memory module 510 as a text. For example, when the display module 520 receives the third information message from the memory module 510, the display module 520 may output a character of “0000 vehicle loading failure” as shown in the first display module 521 of FIG. 5. . In addition, when the display module 520 receives the third information message from the memory module 510, the display module 520 may output the text “transmission of the vehicle information to the police station” as shown in the second display module 522 of FIG. 5. In addition, the display module 520 may transmit the data represented by the text to the text-to-speech output unit 501.

The communication module 550 may be connected to the server 60 managed by a public office such as a police station to enable wireless data communication, and may transmit information output from the display module to the server.

The text-to-speech output unit 501 outputs the text output from the display module 520 as a voice. That is, the text-to-speech output unit 501 may output the text as it is displayed on the display module 520 as sound. The text-to-speech output unit 501 may be a Text To Speech (TTS) program that outputs various set characters as sounds.

The text-to-speech output unit 501 may output the text “0000 vehicle loading failure” to the display module 520 as a voice.

In this way, the present invention detects a poor loading vehicle, and outputs the detected information as a text and sound in the display module 520, so that the driver can recognize the loading state of the load on his vehicle. In addition, the present invention informs the driver that the load is not loaded correctly, and provides the vehicle information to the police station if the load of the vehicle is not changed to the loaded state thereafter.

According to the present invention, when the vehicle is detected, the electric signboard unit is operated while detecting the loading state of the detected vehicle so that the driver may be alert to the loading state of the vehicle so that an accident does not occur due to an unstable load.
