[0031] In use:

[0032] When the offshore worker falls into the water or encounters danger at sea, the water immersion delay conductive control assembly 2 is automatically started (or manually started through the manual control switch 10), sends a distress signal to the maritime search and rescue center, and broadcasts a Beidou short message for help (the sent message information is transmitted to the relevant search and rescue center through the Beidou satellite, and the short message contains the identification code of the person in distress, the contact number, the identification code of the ship, the emergency contact number and the Beidou positioning data, etc., which will help the search and rescue center to take appropriate action to rescue the person in distress), and the search and rescue center sends a confirmation message to the fallen person and sends search and rescue forces.

[0033] Specifically, when the offshore worker falls into the water or the ship, offshore facilities are in distress, the personnel need emergency assistance or abandon ship to escape,

[0034] 1. When the personnel are conscious and can operate independently, only need to manually press the manual control switch 10 to start the Beidou short message sending function of the device, and the device will automatically send a distress short message every certain time until the manual termination of the sending or the energy depletion of the battery 3.

[0035] 2. When the personnel are injured and unconscious and cannot operate independently, the device automatically connects the power supply after the time of continuous immersion in seawater reaches 5 minutes. Since the seawater switch has been connected, the device starts to automatically send the distress alarm Beidou short message information. The device will automatically send a distress short message every certain time until the manual termination of the sending or the energy depletion of the battery 3.

[0036] In order to save the battery energy of the device, prolong the working time, and reduce the occupation of the Beidou short message channel, increase the probability of being rescued, when the device starts the distress short message sending function, the first information sent contains the distress personnel identification code, contact method, emergency contact phone and Beidou positioning data. Every 15 minutes, a Beidou short message is automatically sent, which contains the distress personnel identification code and Beidou positioning data.

[0037] After receiving the distress short message, the search and rescue center will send a "received" confirmation information to the distress device through Beidou, and start the search and rescue program.

[0038] After receiving the "received" confirmation information, the device automatically adjusts the subsequent message sending time interval to 30 minutes. If the device continuously sends 8 short messages and does not receive the "received" confirmation information, it will also automatically adjust the subsequent message sending time interval to 30 minutes to reduce the consumption of the device battery 3.

[0039] If the distress is resolved or the personnel are rescued, self-help is successful, manually press the corresponding termination manual control switch 10, the device will send the last "risk resolution" short message to the outside, prompt the risk resolution, and then terminate the sending.

[0040] The device can be connected to external equipment through the data transmission interface 13 to preset the personnel identification code, contact phone, ship identification code, emergency contact phone and other information of the controller 23 in advance.

[0041] The principles of the above operation control and the preset of related content are the existing Changshu technology, which will not be further described here.

[0042] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
