DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In the present specification, when any one element 'transmits' data or signals to another element, the element can transmit the data or signal directly to the other element, and through at least one other element Data or signal can be transmitted to another component.

FIG. 1 is a view for explaining that a boarding gate 4 of a train 1 is formed differently for the installation of an Arduino-based train boarding gate guiding system 100 according to an embodiment of the present invention. 2 is a plan view of the Arduino-based train boarding gate guiding system 100 according to the embodiment of the present invention installed in the history 2, and FIG. 3 is a front view of the Arduino- to be.

1, when the train 1 stops in the history 2, the position of the boarding gate 4 varies depending on the type of the train 1, and the number of the boarding passages 4 for each train 1 and The size of the train 1 may be different for each size of the train 1. In this way, the position of the boarding gate 4 is not shaped and the length of the train 1 is formed differently. Thus, it is difficult to find the position of the boarding pass 4 in the case of a visually impaired person with an uncomfortable eye.

2 and 3, the Arduino-based train boarding guide system 100 includes an infrared transmitter 110 mounted to the lower end of the boarding gate 4 of the train 1, The infrared receiver 120 is mounted on the bracket 2a and the vibrator 130 and the arcuino 140 are provided below the braille bracket 3. [ Here, the vibrator 130 may be formed by forming a groove on the upper side of the braille scaffold 3 and attaching it to the groove.

The infrared ray transmitter 110 and the infrared ray receiver 120 are installed on the same plane on the vertical plane or within a preset infrared ray receiving error range and the infrared rays irradiated from the infrared ray transmitter 110 are transmitted to the infrared ray receiver 120 ), The vibrator 130 is used to vibrate after a predetermined time (for example, about 3 seconds) to guide the position of the boarding gate 4 to the visually impaired.

A vibrator 130 is attached to or inserted into the scaffold block unit 3u of each braille scaffold 3 and connected to one of the arduino 140 and the power line Data bus.

The infrared transmitter 110 mounted on the train 1 and the infrared receiver 120 attached to the area set to the gate 4 position in the history 2 are aligned on the horizontal plane and judged by the Adouno 140 The vibrator 130 of the braille base 3 controls the vibration. That is, when the positions of the infrared ray receiver 120 and the infrared ray transmitter 110 coincide with each other, they are recognized as operation signals and the motor 130 is operated.

On the other hand, when the infrared transmitter 110 and the infrared receiver 120 are used, there is an advantage that the current consumption is small and the volume is small as compared with the ultrasonic sensor. There are advantages. Therefore, it is possible to provide the Arduino-based train gate guiding system 100 simply by using the infrared transmitter 110 and the infrared receiver 120, but it is possible to perform precise measurement compared with the ultrasonic sensor even with simple logic.

It is also possible to provide the light source effect to the braille scaffold 3 through the LED display window without using the vibrator 130 in such a way as to indicate the position of the gate 4 of the train 1, , It is not suitable as a method of notifying the blind person. Therefore, the present invention uses the vibrator 130 that provides an immediate effect that can stimulate the body through vibration.

FIG. 4 is a block diagram specifically illustrating a configuration of an Arduino-based train boarding guide system 100 according to an embodiment of the present invention.

4, the train boarding guide system 100 includes a plurality of infrared transmitters 110, a plurality of infrared receivers 120, a plurality of vibrators 130, and an Arduino 140, as described above, .

The position checking means 141 waits for an infrared signal for the predetermined number of infrared receivers 120 assigned thereto. When the reception of the infrared signal is started, the position confirming means 141 receives the infrared signal (stop signal) from the one of the plurality of infrared transmitters 120 attached to the lower end of the gate 4 of the train 1 And waits for reception.

The position checking means 141 extracts the vibrator serial number provided on the braille board 3 matching with the infrared receiver 120 receiving the infrared signal for a predetermined time or more.

More specifically, the positioning means 141 includes an infrared receiver 120 receiving the stop signal among the infrared transmitters 110 individually formed at the gate 4 of the train 1 and a braille pedal 3 The position of the vibrator 130 formed on the vibrator 130 is identified.

Next, the vibration control means 142 transmits the vibration control signal to the vibrator 130 corresponding to the extracted vibrator serial number by the position identification process by the position confirmation means 141, The vibration is transmitted to the braille base 3 provided by the bracket 130, so that it is possible to move along the strong vibration in the surroundings.

On the other hand, the Arduino 140 corresponds to a device control board incorporating a micro controller for an open source, and the infrared receiver 120, the vibrator 130, and other devices are connected to a control board And 'open source hardware' that connects with an external terminal and loads software and operates.

The extension control means 143 can provide voice guidance when the audio output device is additionally mounted in addition to the infrared receiver 120 and the vibrator 130 mounted on the Arduino 140 substrate. The extension control means 143 transmits and receives data to and from the control terminal 200 corresponding to an external terminal so that the minimum power use state of the devices mounted on the board 140 according to entry of the train 1 And a wake-up control for switching from a sleeping state to an active state.

FIG. 5 is a flowchart illustrating a method of guiding an Arduino-based train gates according to an embodiment of the present invention.

5, each of the plurality of arduino 140 that has received the wake-up signal from the control terminal 200 according to the entry of the train 1, And waits for an infrared signal for a predetermined number of infrared ray receivers 120 formed on the braille stage 3 (S111).

To this end, the scaffolding block unit 3u forming the braille scaffold 3 formed in the history 2 must have one arduino 140 for each of the preset number of scaffolds, (2) The infrared receiver 120 should be installed separately at the position of the platform lower end 2a.

 The plurality of infrared transmitters 120 attached to the lower end of the gate 4 of the train 1 through the predetermined number of IR receivers 120 for management, The infrared signal is received at a predetermined time or longer than the predetermined time (S112).

After step S112, the arduino 140 extracts the oscillator serial number provided in the braille board 3 matching with the infrared receiver 120 receiving the infrared signal for a predetermined time or more (S113).

After step S113, the arduino 140 transmits a vibration control signal to the vibrator 130 corresponding to the extracted vibrator serial number (S114). Here, the vibrator serial number corresponds to one formed with one infrared receiver 120 receiving the infrared signal at a predetermined time or more in step S112.

After step S114, the Adouino 140 recognizes the interruption of the infrared signal received from the infrared ray transmitter 110 to the infrared ray receiver 120 according to step S112 (S115).

After step S115, the Arduino 140 transmits the departure or departure information of the train 1 to the control terminal 200 (S116). Accordingly, the control terminal 200 judges that the train 1 has started normally when it receives the departure or departure information from the arithmetic unit 140 of the threshold value or more. If the train 1 is below the threshold, the control terminal 200 determines abnormally, And outputs an inspection signal to the boarding gate guiding system 100, thereby providing an advantage that the boarding system 100 of the train boarding gate based on the adunion can be checked by itself.
