DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the scope of the present invention should be understood from the description of the claims. Further, the description of known technology which obscures the gist of the present invention is omitted.

The inter-ship emergency notification system using BLE (Bluetooth Low Energy) and GPS according to the present invention is composed of a GPS module 100, a Bluetooth module 200 and an emergency notification application 300 provided in each ship as shown in FIG. 2, The ship is divided into a charity line 50 to be a signal sensing subject and a pair of lines 61, 62, 63 and 64 to be subjected to signal sensing.

The GPS module 100 receives the GPS signal from the GPS satellite 10 and extracts the position information of the charity line. The GPS module 100 provided on the other line similarly extracts the position information of the other line.

The Bluetooth module 200 transmits and receives a Bluetooth signal including positional information extracted from the GPS module 100, and includes a beacon receiving unit 210 for receiving a beacon signal from another line within a range, And a beacon dispatcher 220.

The emergency notification application 300 detects the approach of the other line using the Bluetooth module 200. The emergency notification application 300 includes a signal processing module 310, a communication management module 320, a distance analysis module 330, And an audio processor 340.

The signal processing module 310 extracts position information of the other line using the beacon signal received by the beacon receiving unit 210 and includes a MAC address verifying unit 311, a positional information extracting unit 312, An audio output unit 314, and a bidirectional communication unit 315. The audio output unit 314,

The MAC address verification unit 311 extracts a MAC address from the beacon signal received by the beacon reception unit 210 and verifies whether the MAC address is included in the MAC address list stored by the communication management module 320. If it is included in the MAC address list, it is a previously connected Bluetooth module, so it can automatically try to connect without approval.

The position information extracting unit 312 extracts a latitude value and a latitude value from the position information included in the beacon signal received by the beacon receiving unit 210. In addition, . When the Eddystone protocol of the BLE protocol is applied, a method of synthesizing the location information with the beacon signal is as shown in FIGS. 4 and 6, in which the location information (D ).

The location information synthesis unit 313 synthesizes the position information of the charity extracted by the GPS module 100 into a beacon signal to be transmitted from the beacon transmission unit 220, The position information synthesized in the signal is extracted.

The audio output unit 314 outputs the audio signal generated by the audio processor 340 through the audio output apparatus when the distance analyzed by the distance analysis module 330 is a state in which the other line is not paired . If the Bluetooth module is paired with the other line Bluetooth module, the emergency communication can be informed by transmitting a warning message through the Bluetooth communication using the two-way communication unit 315. However, since the two- (dB) of audio signals to warn of an emergency such as immediately before a collision.

The bidirectional communication unit 315 transmits an emergency notification message such as a collision warning message through Bluetooth communication when the distance analyzed by the distance analysis module 330 is a paired state of a certain line or less.

The communication management module 320 controls the pairing between the charity Bluetooth module 200 and the Bluetooth module of the other line. The communication management module 320 includes a pairing control unit 321 and a MAC address collecting unit 322.

When the MAC address checking unit 311 confirms the MAC address included in the MAC address list of the communication management module 320, the pairing control unit 321 attempts to pair with the corresponding Bluetooth module. This is a reliable module that recognizes that there is a history that has been previously paired, so it tries to automatically pair.

The MAC address collection unit 322 stores the MAC address of the other pair paired by the pairing control unit 321 in the MAC address list. That is, if there is a history paired once, the module is also a reliable module, so that it is stored in advance in the MAC address list so that it can be automatically paired by the pairing control section 321.

The distance analysis module 330 analyzes the distance between the charity line and the other line using the position information of the other line extracted from the signal processing module 310 and the position information of the charity line extracted from the GPS module 100. Specifically, the distance is calculated using the latitude and longitude values of the other line extracted by the position information extraction unit 312 and the latitude and longitude values of the charity line.

The audio processor 340 generates an audio signal of a level detectable on the other line when the distance analyzed by the distance analysis module 330 is less than a predetermined reference level. And generates an audio signal of a corresponding level according to the distance analyzed by the distance analysis module 330. [ At this time, the audio signal means a warning sound or a warning message.

The method of emergency notification between ship using BLE and GPS using the above system is as follows.

Step 1 : Synthesize the position information acquired from the GPS module on the other line with the beacon signal

Specifically, according to the Edistone protocol, the location information is stored at the location of the Eddystone-URL.

Step 2 : In the first step, the beacon signal synthesizing the position information is transmitted

The beacon signal in which the GPS position information is synthesized is transmitted in four directions by the Bluetooth module.

Step 3 : The beacon signal transmitted in the second step is received from the Bluetooth module of the charity line within the first distance range A1

Referring to FIG. 1, the first distance A1 is an area where the second line 62 and the third line 63 are located and is a region where the Bluetooth signal is sensed but is weak in signal sensitivity for pairing . That is, it is an area where information included in the unilaterally received Bluetooth signal can be read, and corresponds to an area having a radius of 500 m to 1 km (r1 = 500 m, r2 = 500 m). The beacon signals of the other lines 62 and 63 are received automatically because they are within the range and the beacon signal of the fourth line 64 outside the area does not reach the charger 50. [

Step 4 : Extract MAC address and location information from the beacon signal of the other line received in the third step

Step 5 : Check whether the MAC address extracted in Step 4 is included in the pre-stored MAC address list

If it is confirmed by the MAC address included in the MAC address list, it is recognized that there is a previously paired history, so that it is a reliable module so as to automatically attempt pairing.

Step 6 : In step 5, if the MAC address is included in the MAC address list, it is attempted to pair with the Bluetooth module of the corresponding line

Step 7-1 : If the pairing is successful in the sixth step, an urgent message is transmitted to the line by Bluetooth communication

Since the pairing is successful in the sixth step, the distance information and the approach direction between the ships are calculated by exchanging position information with each other through the Bluetooth communication. Emergency messages may include a message to notify a collision warning, as well as an approach direction, a distance, and a avoidance direction considering the approach direction.

Step 7-2 : If the pairing is unsuccessful in the sixth step, the position information of the other line extracted in the fourth step is compared with the position information of the charity line acquired through the GPS module of the charity, and if it is within the first range Outputs a detectable audio signal on the track

The first distance A1 is a region where the first hit line 61 is located in FIG. 1, and not only a beacon signal is sensed but also a degree of signal sensitivity that can be paired is ensured, so that bidirectional communication with the charity 50 It is a possible area.

The audio signal that can be detected on the other line is a level (dB or the like) of the audio signal that can be detected according to the distance, and generates an audio signal of the corresponding level according to the distance obtained by analyzing the distance between the other line and the charger. At this time, the audio signal means a warning sound or a warning message.

Step 7-3 : If the pairing fails in the sixth step, the position information of the other line extracted in the fourth step is compared with the position information of the charity line acquired through the GPS module of the charity, and if it is within the second range (A2) Provide navigation guide to operate collision warning system and to avoid collision considering approach direction of other ship

Within the second range (A2), the approach is within the danger range, so you can avoid this by taking into account the approach direction and the distance of the battle line, as well as warn the battle line, It is possible to provide an optimal navigation guide and to control the navigation route of the ship automatically when connected to the automatic navigation system of the ship.

5 is a graph showing a comparison between the distance measured by the conventional Tx and the RSSI method (Existed System) and the distance measured by the method of the present invention (Proposed System) under the sea condition. In this case, the distance measured by the present invention is similar to the actual distance, whereas the existing system has a problem in the distance measurement at the sea.

According to the present invention, in order to solve the problem of unreliability of distance calculation using only RSSI of wireless communication, it is possible to transmit GPS information by modifying transmission data format of BLE, thereby improving reliability of distance.

In addition, by transmitting Broadcasting GPS information between transmission and transmission of the communication, it is possible to calculate the distance between the vessels without pairing, and it is possible to predict the distance to the user through different notifications according to the distance .

In addition, pairing between ships can be used to send and send messages and information between similar vessels. It is faster than existing VHFs and has high traffic volume, so there is no difficulty in linking with LTE communications.

Since the equipment cost is low in the present invention, there is no difficulty in constructing and operating separately for all vessels in addition to the AIS system.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be clear to those who have knowledge.
