The strength of the received signal (RSSI) can be analyzed to monitor the exact position of the passenger on board.

For example, as shown in FIGS. 9 and 10, the zones were differentiated to estimate the position on board. This is a case where a user who attaches a smart tag type terminal 100b for passengers is located in a zone B under the assumption that the IoT gateway device 200 is installed at the right end of the corridor.

A user wearing the passenger smart tag type terminal (100b) can know whether the user was headed to the A-1 zone or B-1 zone when the short-range wireless signal of the B zone, that is, the beacon There will be no.

In this case, the IoT gateway device 200, the central control server 300, and / or the external terminals 20, 30, and 400 may transmit the radio signal strength (LoRa RSSI) value and current transmission of the last received beacon information.

If it is determined that the mobile station has moved, otherwise, it is determined that the mobile station has moved to the B-1 region if the LoRa RSSI value of the currently transmitted radio signal is smaller than the LoRa RSSI value of the last received data.

However, it is difficult to measure the position of the ship only by the receiving strength of the passengers' smart tag type terminal 100b and the beacon in the ship's bulkhead made of digging and aluminum plate.

Therefore, it is possible to increase the accuracy of the position measurement by using the direction sensor, that is, the source motion detector (not shown) or the passenger motion detector 180b.

If beacon information is received while receiving the LoRa RSSI, the location of the beacon is displayed as the current location.

If the beacon information is not received, the radio signal intensity (LoRa RSSI) value when the last information of the beacon is received is compared with the current radio signal intensity (LoRa RSSI) value. After comparison, the direction sensor, that is, the source motion detector (not shown) or the passenger motion detector 180b is compared in the same direction, and if the position is changed, and if the direction is not matched with the direction sensor, the CNT is '0' Do not change the location. The CNT checks that the beacon is entered in the shadow area when no beacon is received, and at the same time, it is made only once, so as not to change the location continuously.

After the step (b-3),
The terminal identification information and the object identification information together with the terminal location information of each object for the IoT smart terminal encrypted through the application service connection module to provide a cloud computing service in response to a request of an external client terminal Further comprising the step of providing a service to be periodically transmitted to the cloud server,
The unique terminal identification information for the IoT smart terminal may include the name of the IoT smart terminal, the password of the IoT smart terminal, the serial number of the IoT smart terminal, the type of the IoT smart terminal, the manufacturer of the IoT smart terminal, the MAC of the IoT smart terminal. IoT smart device generated by a media access control (IP) address, a unique IP (Internet Protocol) address of the IoT smart device, a model of the IoT smart device and a version of the IoT smart device, a secret key of the IoT smart device, or a PKI-based private key At least one of authentication information of,
The unique object identification information for the IoT smart terminal may include the name of the object, the password of the object, the resident number of the object, the telephone number of the object, the address of the object, the biometric information of the object, the public key infrastructure of the object, Ship using wireless communication, characterized in that it comprises at least one information of the object OTP (One Time Password), the object's authorized certificate information, the object's serial number, the type of the object, the manufacturer of the object, the object's authentication information How to position my object.
The method according to claim 1 or 2,
After step (c) or after step (d),
Analyzing the relationship of each object based on the unique terminal identification information and the object identification information together with the terminal location information of each object transmitted in the step (b) through the central control server to estimate the movement path of each object and the time And calculating a situation by using ontology-based contextual cognition modeling by reflecting the movement pattern and the characteristics of space of each object. Positioning method.
The method of claim 1,
In the step (c), the central control server matches the terminal position of each object to the layout of the corresponding vessel previously stored based on the unique terminal identification information together with the terminal position information of each object transmitted in the step (b). In addition, by matching the terminal location information of each object in the vessel with the pre-stored location information of the sea with a pre-stored Geographic Information System (GIS) map, the display screen allows the administrator to accurately monitor the terminal location of each object. Positioning method of the object in the ship using a wireless communication, characterized in that the visual display.
The method of claim 1,
After any of the steps (a) to (c),
A unique terminal along with terminal location information or biosignal information of each object wirelessly transmitted from the IoT smart terminal or the IoT gateway device through a search scanner mounted on a mobile means for rescue of a ship's distress when a ship is distressed And visually displaying the terminal location or the biosignal of each object on a display screen so as to accurately and easily monitor the terminal location or the biosignal of each object based on the identification information. Positioning method of the object in the ship using wireless communication, characterized in that.
