Description

TECHNICAL FIELD [0001] The present invention relates to a low-power Bluetooth-based pedestrian danger warning system, and a service method thereof. BACKGROUND OF THE INVENTION 1. Field of the Invention [0002]

More particularly, the present invention relates to a pedestrian risk warning system and a service method thereof. More particularly, the present invention relates to a pedestrian risk warning system and a service method thereof, A low-power Bluetooth-based pedestrian risk warning system and its service method capable of preventing accidents.

In recent years, as the living environment has been generally improved, the number of vehicles to be supplied has been greatly increased. Accordingly, the traffic accident notice area (TNA) (for example, a pedestrian crossing area) The question of how to effectively reduce accidents is emerging as a very important social issue.

In the conventional case, in consideration of the above-mentioned social issues, the traffic management institutions (police agencies, traffic facility management institutions, administrative agencies, etc.) additionally install pedestrian traffic lights and driver traffic lights around each TNA, By giving each of the drivers a series of traffic rules such as " when the red traffic light is lit, stopping or running and stopping or running only when the green traffic light is lit " The accident is blocked in advance.

However, even in situations where these pedestrian traffic lights and driver's traffic lights are equipped, various unexpected situations such as pedestrians (especially young children or elderly persons) may not be able to recognize the fact that the green traffic lights or the red traffic lights are lit Or the driver ignores the blinking of the traffic lights for the driver, the pedestrian or the driver must be exposed to serious traffic accidents despite the normal installation of the traffic lights.

Of course, it senses in real time the fact that the traffic lights are turned on, the fact that the vehicle (driver) is in violation of the traffic signal, and the fact that the pedestrian is unauthorized traffic, and actively notifies the parties (pedestrian, driver) However, in the conventional case, it is necessary to inform the pedestrian side of the estimated time of extinction of green or the like in the vicinity of the TNA, Since only the device was installed and provided as a supplementary device, the traffic management agency had to face many difficulties in drastically suppressing traffic accidents that occurred in the vicinity of TNA.

Meanwhile, VANETs (Vehicular Ad-hoc Networks, hereinafter referred to as "VANETs") are emerging in order to improve technical limitations on the sharing of more accurate and rapid traffic situation information. VANETs are largely divided into two types of communications, the first being Vehicle to Vehicle (V2V) communication. V2V means vehicle-to-vehicle communication. Through V2V, the driver of the vehicle can see more direct and more traffic situation information in real time and induce him to perform defensive driving or safe driving. The second is a vehicle-to-infrastructure (Vehicle to Infrastructure: V2I) communication, which connects to the Internet via V2I to acquire the desired information or receive data for convenience. to provide. VANETs applications to increase the safety of pedestrians have also been studied.

However, since such VANETs can not track user's location data, they are not prepared for accidents from pedestrians. Especially, accident prevention such as location information on pedestrians in dangerous area The vehicle can not acquire the information for the vehicle. Therefore, there is a problem in that it is somewhat insufficient as a technique for inducing safe driving with a limited sharing of information.

Therefore, in order to more accurately and quickly share information about traffic volume and pedestrians in real time, vehicles traveling in an accident hazard area or an accident lot area can receive pedestrian information, thereby inducing safe driving, A pedestrian risk warning system and its service are needed to prevent traffic accidents by ventilation.

As shown in FIG. 1, the pedestrian risk alarm system according to the embodiment of the present invention receives GPS data and periodically acquires its own position information, and the acquired position information is included in a predetermined alert area A mobile device 100 for a pedestrian that periodically broadcasts a beacon signal of a warning message via an embedded beacon device; And a vehicle beacon terminal (200) for displaying safe driving warning information when the beacon signal is received from the pedestrian mobile device (100) by a terminal equipped with a beacon device do.

As described above, in the embodiment of the present invention, when a pedestrian is walking in an accident area (crosswalk, intersection, etc.) or in an alert area such as an accident lot area, the vehicle traveling around the warning area has a pedestrian The alerting system transmits a warning message using a beacon device, receives a warning message through a beacon device built in a navigation terminal installed in the vehicle, and displays the received message on the terminal, thereby inducing safe driving and preventing an accident Provide a pedestrian risk warning system.

In general, pedestrians in modern society are equipped with mobile devices such as smart phones, and smart phones are equipped with Bluetooth, which is a short distance wireless communication device. Therefore, the position of pedestrians or personal data is communicated between the driver and pedestrians Lt; / RTI >

Particularly, Bluetooth Low Energy (hereinafter referred to as "BLE") communication is a communication for detecting the location of a user using RSS (Received Signal Strength) Scanning is used to detect presence, and the device periodically transmits its location in the form of broadcast or broadcast in order to indicate the location and presence of the device.

As described above, according to the embodiment of the present invention, the beacon terminal 200 provided in the traveling vehicle communicates with the pedestrian mobile device 100 using the BLE-based beacon device, And by exchanging with each other, it is proposed to induce safe driving in the warning area and prevent accidents.

 As shown in FIG. 1, a zone in which a pedestrian carrying a mobile device moves is defined as an alert area, and a zone in an alert area is defined as an alert area The area where the accident is likely to occur due to the high number of pedestrian movements, or statically, a lot of accident areas are determined and set in advance.

Pedestrian danger zones such as an intersection, a crosswalk, and a predetermined accident bundle zone are preset in an alerting area in the mobile device 100 for a pedestrian or the beacon terminal 200 for a vehicle and are matched with a map, It periodically determines whether the position of the device or the beacon terminal 200 is in the warning area.

That is, the position of the pedestrian is grasped by receiving the GPS data periodically (1s) using the smart device which is the mobile device possessed by the pedestrian, and the detected position is compared with the position in proximity to the alert area or the safe area Then, if it detects that the pedestrian has entered the alert area, it transmits a warning message of safe driving to the surrounding vehicles through the BLE communication of the beacon device. Then, the vehicles receiving the warning message display a warning message of safe operation through the terminal, recognize the message by the driver, recognize that there is a person nearby, and induce them to drive safely.

In addition, the beacon terminal 200 of the vehicle receiving the message transmits the safety gait message to the mobile device 100 for the pedestrian, and the pedestrian receiving the safety gait message confirms the existence of the vehicle in the vicinity, .

That is, in the embodiment of the present invention, the communication between the mobile device of the pedestrian and the beacon terminal 200 of the traveling vehicle uses a beacon device using Bluetooth (BLE) communication based on low power to quickly and accurately Pedestrian risk warning system will be provided.

Here, the beacon device refers to a device that uses a beacon communication technology. The beacon detects the position of a user using RSS (Received Signal Strength) based on Bluetooth low energy (BLE) communication. Is a short distance communication technology.

It is characterized by low cost, high persistence and independent platform based on existing Bluetooth communication and other low power communication. Unlike existing location tracking technology, the basic location tracking method of the above communication is a method that can be detected when a user accesses the beacon zone using a device capable of receiving BLE communication. Here, the beacon zone refers to a radius area where a message can be received through a beacon device.

Therefore, Beacon has location recognition or context recognition technology suitable for short distance communication and various services are being developed using near distance measurement and tracking.

More specifically, Beacon is a next-generation smartphone short-range communication technology through low-power Bluetooth (BLE). It is a smartphone short-range communication technology that enables users to locate a user within a radius of 50 to 70 meters, Technology. It is suitable for O2O (On line to Off line) service that connects online and offline because of the longer available distance than NFC (Near Field Communication), and accuracy is high enough to distinguish 5 ~ 10cm unit.

In addition, using this technology, various services can be implemented using a guidance service, a mobile coupon, and the like at a specific place, a battery consumption of a smart phone is low due to low power, There is an advantage that the pairing for the "

Therefore, in the embodiment of the present invention, by using a low-power-based Bluetooth (BLE) communication device, a mobile terminal such as a smart phone generally possessed by a pedestrian and a beacon device To broadcast a pedestrian risk warning message in a warning area and to display a warning message on the navigation terminal of the driving vehicle without pairing when the vehicle enters the warning area, It provides an efficient pedestrian risk warning system that can induce safe driving for pedestrian safety and prevent traffic accidents.

Here, the vehicle beacon terminal 200 may be any computing device provided with a beacon device such as a navigation-only terminal, a smartphone equipped with a navigation application app, and a vehicle computer. The display of the warning message can be variously outputted and displayed on the beacon terminal 200 such as a navigation terminal provided in the traveling vehicle by means of video information, audio information, and vibration information.

Here, the navigation dedicated terminal is provided in the vehicle, and includes a GPS receiver as a terminal for providing a desired destination route information by a user, and acquires position information of the vehicle by receiving GPS signals, A display device for displaying navigation information including a road map, traffic information, and other additional information previously stored or obtained by communicating with the outside, and a processor for processing a program for providing such navigation information One of the configured computing devices.

2 is a flowchart illustrating a low-power Bluetooth-based pedestrian risk alarm service method according to another embodiment of the present invention. 2, the pedestrian risk alarm service method according to an embodiment of the present invention includes a pedestrian risk alarm system including a mobile device 100 for a pedestrian equipped with a beacon device and a beacon terminal 200 for a vehicle The method includes: (a) receiving GPS data periodically from the mobile device for a pedestrian (100) and acquiring its own position information (S100); (b) determining whether the positional information obtained by the pedestrian mobile device (100) is included in a preset warning area (S200); (c) periodically broadcasting (S300) a beacon signal of the warning message when it is determined that the pedestrian mobile device 100 is included in the warning area; And (d) displaying safe driving warning information when the beacon terminal 200 receives the emitted beacon signal (S400). The embodiment of FIG. 2 illustrates a low power Bluetooth based pedestrian risk alert service method using the system of the embodiment of FIG.

As shown in FIG. 2, step (a) (S100) is a step in which the mobile device 100 for a pedestrian acquires its own position information and periodically receives GPS data through a GPS receiving device built in the mobile device And acquiring location information of the mobile device by matching received GPS data with previously stored map information. In FIG. 2, GPS data is periodically received at 0.5 second intervals.

In step (b), it is determined whether or not the acquired location information is included in a preset warning area, and the map of the warning area stored in advance in the mobile device and the map of the warning area acquired through the GPS data The location information is matched to determine whether the mobile device is located in the warning area. Here, the alert area is a pedestrian-dangerous area such as an intersection, a crosswalk, and a pre-set accident bundle area, as described above.

In step (b), it is determined whether or not the location information acquired by the pedestrian mobile device 100 is included in a preset warning area, and an alert mode (Alert Mode) for activating the beacon device according to the determination result. Or to a safe mode (inactive mode).

Performing the process of switching the alert mode (Alert Mode) or the secure mode (Secure) depending on whether the mobile device is located in the alert area minimizes the broadening of the beacon signal, .

That is, when the pedestrian mobile device 100 is switched to the safe mode, the beacon device is disabled by not broadcasting the beacon signal of the warning message, thereby reducing communication power loss of the mobile device, The channel preemption due to signal broadcasting can be reduced, and communication collision can be reduced.

More specifically, as shown in FIG. 2, in the embodiment of the present invention, a mobile device 100 for a pedestrian and a beacon terminal 200 for a vehicle, which are capable of BLE communication, are required and are divided into two states, And communication with the user. The first state is Alert Mode. If the location is calculated by periodically receiving the GPS data and the alert area is detected, the state changes to beacon signal broadcasting and the safety operation message is transmitted to the vehicle in 0.2 second intervals.

In this case, since the beacon signal of the broadcast type transmits a warning message to all vehicles in the vicinity of the pedestrian, unlike the general WIFI or Bluetooth method, a warning message is transmitted without any constant pairing, It is possible to induce the driver to perform safe driving.

The second state is Secure Mode. If GPS data is detected as in a safe area, stop the state and disable the beacon to not send a warning message. As described above, since the mobile device of the pedestrian transmits in broadcast form only in the warning area, the battery efficiency of the mobile device can be increased and the communication preemption can be minimized by reducing channel preemption due to indiscriminate beacon signal broadcasting This is because there are advantages.

The step (c) is a step of periodically broadcasting a beacon signal of the warning message when the mobile device 100 for a pedestrian is included in the warning area. In the example of FIG. 2, The alert message is transmitted in the form of broadcast (Alert message Broadcast).

When a mobile device having a beacon device based on BLE communication transmits a beacon signal of a warning message in a broadcast form, the beacon device is located in an area where the beacon signal can be received or in a warning area The present invention is advantageous in that BLE communication can be implemented easily and quickly without any troublesome procedure such as specifying or registering a device that can receive and receive.

The step (d) is an output step of displaying the safe driving warning information to be verified by the driver when the beacon signal emitted from the mobile device is received by the beacon terminal 200 of the vehicle. Here, it is preferable that the safe driving warning information is displayed by at least one of voice information, image information, and vibration information through the beacon terminal 200, and the navigation information displayed on the beacon terminal 200 And is preferably displayed by at least one of audio information, image information, and vibration information.

That is, it is also possible to transmit a voice message through a voice message to the vehicle driver in order to remind the driver that the pedestrian is in the vicinity of the warning area, and to display the additional information in the navigation information of the navigation terminal It is also possible that the beacon terminal 200 is vibrated and provided to the driver. In addition, the beacon terminal 200 may output the safe driving warning information in various manners, accurately transmit it to the driver of the vehicle, and remind the driver that it is a pedestrian danger warning area.

The step (d) may further include displaying safety driving warning information and transmitting the safety gait message from the beacon terminal 200 to the pedestrian mobile device 100.

The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Accordingly, the embodiments disclosed herein are for the purpose of describing rather than limiting the technical spirit of the present invention, and it is apparent that the scope of the technical idea of the present invention is not limited by these embodiments. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
