BLE GPS Emergency Notification System and Method between Ships utilizing BLE and GPS

摘要

The present invention relates to a system and a method for notifying a danger by an alarm on board to prevent a collision between ships by using a Bluetooth to receive and transmit a GPS between ships for proper notification regarding access between ships. The present invention has the following effects. That is, in order to solve the unreliable problem of distance calculation using only RSSI of wireless communication, GPS data can be transmitted by modifying the BLE transmission data format, thereby increasing the reliability of the distance. Also, by transmitting GPS information of Broad Casting method between transmission and transmission of communication, the distance between ships can be calculated without pairing, and the user can predict the distance through different notification according to the distance. There is an advantage. In addition, there is an advantage that can be applied to all vessels, including small vessels by using a low-power low-cost Bluetooth method.
