step 1.3), when the first control unit 13 receives an emergency signal, acquiring the position information of the receiver 2 which sends the emergency signal;

and 1.4) controlling the power assembly 12 to operate according to the position information, and driving the ship body 11 to move to the position of the receiver 2 which sends the emergency signal.

Further, the interactive data in step 1.1) includes a first data packet sent by the third communication unit 33 of each spud 3 to the first communication unit 14, where the content of the first data packet includes the number of the spud 3, first time information when the third communication unit 33 sends the first data packet, and first position information acquired by the high-precision GPS module 32 of the spud 3; the communication data in step 1.1 includes second data packets generated by each second communication unit 23 communicating with each third communication unit 33, where the second data packets include contents of third data packets sent by the second communication unit 23 to the third communication unit 33, third time information when the third communication unit 33 receives the third data packets, and second position information acquired by the high-precision GPS module 32 when the third communication unit 33 receives the second data packets; the content of the third data packet includes a corresponding sequence number of the receiver 2, and second time information when the second communication unit 23 sends the third data packet to the third communication unit 33;

step 6.1), the first control unit 13 constructs an array and sets a cycle period, wherein the array comprises a plurality of serial numbers, and each serial number in the array is unique;

step 6.2), the first control unit 13 assigns a unique serial number to the second control unit 22 of each of the receivers 2 in use and synchronizes the time, array and cycle period therewith;

step 6.3), the second control unit 22 of each receiver 2 in the use state sequentially reads the serial numbers in the array at a set frequency at the beginning of each cycle period, compares the read serial numbers with the serial number of the receiver 2, determines whether the read serial numbers are consistent with the serial numbers of the receiver 2, and if the read serial numbers are consistent with the serial numbers of the receiver 2, the second control unit 22 sends a third data packet to the third communication unit 33 of each spud 3.

In the above steps 6.1) -6.3), the receiver 2 is managed based on the self-constructed array, and in actual use, there is frequently a receiver 2 in a use state that enters a non-use state or a new receiver 2 that enters a use state, so the first control unit 13 needs to frequently allocate and withdraw the serial number to and from the second control unit 22, which is troublesome in management. Therefore, in the preferred embodiment, the receivers 2 are managed based on a pseudo-random sequence, specifically, when each receiver 2 enters the use state, the second control unit 22 generates a serial number corresponding to the receiver 2 according to the time of entering the use state, wherein the serial number is a part of the pseudo-random sequence, and since the time of entering the use state of each receiver 2 is different, the serial numbers corresponding to each receiver 2 can be guaranteed to be different from each other; the second control units 22 of all the receivers 2 in use synchronously and cyclically read the pseudo-random sequences, compare whether the currently read serial numbers are consistent with the serial numbers corresponding to the receivers 2, and if so, the second control units 22 send third data packets to the third communication units 33 of the spuds 3. Because the serial numbers of the receivers 2 are different, the time for reading the serial numbers which are consistent with the self serial numbers in the pseudo-random sequence is different, so that the time for sending the third data packets by all the receivers 2 can be staggered, and the condition that packet loss is caused by channel blockage can be effectively prevented from being sent.

Further, the step 1.1) is preceded by the following steps:

and 3.1) generating a distribution map according to the position of the mobile lifeboat 1 and the positions of the receivers 2.

step 4.2), controlling the power assembly 12 to operate to enable the ship body 11 to reach the position where the receiver 2 sending the emergency signal is located along the shortest path.

Further, the spud 3 is mounted on a floating body 4 having a power device and in a floating state, and the third control unit 31 can control the floating body 4 to move; the method further comprises the steps of:

step 5.1), the first control unit 13 judges whether the three positioning piles 3 are collinear according to the positions of the positioning piles 3;

step 5.2), if the three positioning piles 3 are collinear, the first control unit 13 sends an instruction to the third control unit 31 of each positioning pile 3, and each third control unit 31 controls the floating body 4 where the positioning pile 3 is located to move according to the received instruction, so that the three positioning piles 3 are in a triangular layout.
