and S101, the wearable positioning terminal sends the current position information of the ship personnel on the current ship in the current time point to the mobile communication terminal through Bluetooth.
It should be noted that the wearable positioning terminal is used for generating the current position information of the ship personnel on the current ship. Specifically, wearable location terminal can be the device that can fix a position such as location bracelet or location chest card, does not do specific limit to this application. The current location information may be coordinate information of the ship personnel on the current ship. The current time point refers to a time node corresponding to the current system, and the current time node is determined according to a preset transmission time interval of the location information, for example, when the preset transmission time interval of the location information is 1 second, the current time point may be 2022, 8, 9, 10. The mobile communication terminal can be a mobile phone and other communication equipment worn on the body of the ship personnel.
Here, it should be noted that the above examples of the transmission time interval and the current time point are merely examples, and in practice, the transmission time interval and the current time point are not limited to the above examples.
For the step S101, in a specific implementation, the wearable positioning terminal worn on the ship body generates the current position information of the ship personnel on the current ship in real time, and because the wearable positioning terminal and the mobile communication terminal communicate with each other through bluetooth, the wearable positioning terminal sends the current position information of the ship personnel on the current ship in the current time node to the mobile communication terminal through bluetooth.

The first method comprises the following steps: wearable positioning terminal that the boats and ships personnel wore on one's body is connected the back through the bluetooth with the mobile communication terminal that the boats and ships personnel wore on one's body, sends boats and ships personnel's current position information for mobile communication terminal through the bluetooth mode, and after mobile communication terminal received current position information, convey current position information to network center server through the wireless communication network on the current boats and ships. And the second method comprises the following steps: wearable positioning terminal that the boats and ships personnel wore on one's body sends the current position information of boats and ships personnel for setting up the location basic station on current boats and ships through wireless communication network, specifically can send current position information to the location basic station through the loRa network, and after the location basic station received current position information, the location basic station passed through the ethernet and conveys current position information to network center server. The two modes can be mutually redundant and backup, so that even under severe weather and sea conditions, due to the whole ship network coverage, signals cannot be greatly influenced, the normal operation of functions can be ensured, and the monitoring and the alarm for man falling into water under severe conditions are realized.
And S103, the network center server receives the current position information, generates a personnel overboard alarm signal based on the current position information when judging that the current position information is not in the preset ship boundary range corresponding to the current ship, and sends the personnel overboard alarm signal to the broadcast alarm module.
It should be noted that the preset ship boundary range refers to a whole area range which is constructed in advance and corresponds to the current ship. The broadcast alarm module is mainly responsible for broadcasting personnel overboard alarm signals when ship personnel overboard.
For step S103, in a specific implementation, after receiving the current position information of the ship personnel, the network center server determines whether the current position information is located within a preset ship boundary range corresponding to the current ship. And when the current position information is judged not to be in the preset ship boundary range corresponding to the current ship, generating a personnel overboard alarm signal based on the current position information of the ship personnel. And sends the alarm signal of the man falling into the water to the broadcast alarm module. Therefore, the personnel water falling alarm signal carries the position information of the current personnel falling into the water, and the position of the personnel falling into the water can be found by the staff conveniently and immediately. According to the embodiment provided by the application, the preset ship boundary range corresponding to the current ship can be constructed by using the ship model corresponding to the current ship, and how to construct the boundary range is described in detail in the prior art, and is not described herein again.
And S104, the broadcast alarm module receives the personnel overboard alarm signal sent by the network center server and broadcasts the personnel overboard alarm signal to prompt the staff to search and rescue in time.
In the specific implementation of step S104, the broadcast alarm module receives the personnel overboard alarm signal sent by the network center server, and broadcasts the personnel overboard alarm signal to prompt the staff to search and rescue in time. Therefore, when ship personnel fall into water accidentally, the alarm can be given in time, so that the workers can be timely deployed for rescue.

a: the network center server acquires first position information of the ship personnel in a first time point before the current time point and second position information of the ship personnel in a second time point before the first time point.
It should be noted that the first time point refers to a previous time point before the current time point. The second time point is a last time point before the first time point. Continuing with the example in step S101, when the preset transmission time interval of the location information is 1 second and the current time point is 2022 years, 8 months, 9 days, 10, 05, the first time point before the current time point is 2022 years, 8 months, 9 days, 10, 04. The first position information is the position of the ship personnel in the current ship at the first time point, and the second position information is the position of the ship personnel in the current ship at the second time point.

Specifically, the position information determined in step a and the time point corresponding to the position information may obtain an average speed between two adjacent positions through a distance between the two adjacent positions and a time interval between the two positions. The average speed difference value of two intervals formed by three positions is judged by approximately taking the corresponding average speed in the middle of time of each interval, and the acceleration can be obtained when the approximate acceleration is a constant value. How to calculate the acceleration by using the position information and the time point corresponding to the position information is described in detail in the prior art, and is not described herein again.

The acceleration threshold refers to an acceleration value that is set in advance and used for determining whether the current acceleration is too large. The early warning information comprises behavior path information and current position information of ship personnel. Here, the behavior path information refers to a behavior path traveled by ship personnel.
And C, in specific implementation, after the network center server determines the current acceleration of the ship personnel in the current time point, when the current acceleration is judged to be greater than or equal to a preset acceleration threshold value, generating early warning information carrying the behavior path information and the current position information of the ship personnel, and sending the early warning information to the client.
Specifically, for the step C, the network center server determines the behavior path information of the ship personnel through the following steps:
a: and acquiring at least one piece of historical position information of the ship personnel in all historical time points before the current time point.
It should be noted that the historical time point refers to a time point located before the current time point. The historical position information refers to position information of ship personnel on the current ship in historical time points.
Aiming at the step a, in specific implementation, at least one piece of historical position information of the ship personnel in all historical time points before the current time point is obtained.
b: and drawing a behavior path on a ship map corresponding to the current ship based on the at least one piece of historical position information and the current position information to generate behavior path information of the ship personnel.
For the step b, in specific implementation, after determining historical position information of ship personnel in all historical time points, firstly, a ship map corresponding to the current ship is obtained, and then a behavior path is drawn on the ship map corresponding to the current ship based on at least one piece of historical position information and the current position information, so as to generate behavior path information of the ship personnel. Specifically, each piece of historical position information and the current position information can be marked on the ship map to obtain a plurality of marked points, then the marked points corresponding to each piece of historical position information on the ship map are sequentially connected according to the sequence of the historical time points corresponding to each piece of historical position information, and finally the marked points of the current position information on the ship map are connected, so that the behavior path information of ship personnel can be generated.
D: and the client receives and displays the early warning information sent by the network center server.
For the step D, in a specific implementation, after the client receives the early warning information sent by the network center server, the early warning information is displayed in a display interface of the client, that is, the behavior path information and the current position information of the ship personnel are displayed, so as to perform danger early warning on the ship personnel.
As an optional implementation, the automatic alarm method further includes:
(1): and the client responds to relevant operations aiming at ship personnel information corresponding to target ship personnel, generates a position query request corresponding to the target ship personnel, and sends the position query request to the network central server.
It should be noted that the target ship person refers to a ship person who the user wants to view the position information. The ship personnel information may be names of target ship personnel, or head portrait information of the target ship personnel displayed in the display interface, and the like, and the application is not particularly limited.
