As D1 < 50cm, D2 > 50cm, D3 > 50cm, D4 > 50cm, indicate that there are barrier, controllers 8 for right front Control power plant module 7 drives sea life-saving device to be rotated by 90 ° counterclockwise around central shaft, specifically, the control of controller 8 right side Hydraulic propeller 71 is sprayed water toward rear, is rotated by 90 ° sea life-saving device counterclockwise around central shaft；

As D1 > 50cm, D2 < 50cm, D3 > 50cm, D4 > 50cm, indicate that there are barrier, controllers 8 for left front Control power plant module 7 drives sea life-saving device to rotate clockwise 90 ° around central shaft, specifically, the control of controller 8 left side Hydraulic propeller 71 is sprayed water toward rear, is rotated by 90 ° sea life-saving device counterclockwise around central shaft；

As D1 > 50cm, D2 > 50cm, D3 > 50cm, D4 > 50cm, front clear is indicated, controller 8 controls Power plant module 7 drives sea life-saving device to navigate by water toward front, and specifically, controller 8 controls two hydraulic propellers 71 respectively and presses Identical spray force is sprayed water toward rear, so that two hydraulic propellers 71 be made to promote sea life-saving device to navigate toward front jointly Row；

As D1 > 50cm, D2 > 50cm, D3 < 50cm, D4 > 50cm, right is indicated there are barrier, controller 8 is controlled Braking power module 7 drives sea life-saving device to rotate counterclockwise around central shaft, until D3 is greater than 50cm, specifically, controller 8 The hydraulic propeller 71 for controlling right side is sprayed water toward rear, is rotated by 90 ° sea life-saving device counterclockwise around central shaft, until D3 Greater than 50cm；

As D1 > 50cm, D2 > 50cm, D3 > 50cm, D4 < 50cm, left is indicated there are barrier, controller 8 is controlled Braking power module 7 drives sea life-saving device to rotate clockwise around central shaft, until D4 is greater than 50cm, specifically, controller 8 The hydraulic propeller 71 for controlling left side is sprayed water toward rear, rotates clockwise sea life-saving device around central shaft, until D4 big In 50cm；

As D1 < 50cm, D2 < 50cm, D3 < 50cm, D4 < 50cm, indicate that front, the left and right all have obstacle Object, controller 8 control power plant module 7 and sea life-saving device are driven to navigate by water toward rear, until when D1 > 50cm, D2 > 50cm, control Braking power module 7 drives sea life-saving device to be rotated about its center axis 90 °, and specific Controller Defaults 8 control two hydraulic jet propulsions Device 71 is sprayed water by identical spray force toward front, navigates by water sea life-saving device toward rear, until D1 > 50cm, D2 > When 50cm, the hydraulic propeller 71 in the control of controller 8 left side is sprayed water toward rear, keeps sea life-saving device clockwise around central shaft It is rotated by 90 °.

Specifically, before using the sea life-saving device, operator is arranged according to sea situation using the program in controller 8 Module is placed obstacles the safe distance L1 of object and sea life-saving device and rescuing for setting target drowning people and sea life-saving device Distance L2 is helped, L1 is 50cm in the present embodiment, is respectively equipped in each infrared anti-collision module and each pyroelectric infrared sensor module Alarm module.Then at sea in lifesaving appliance traveling process, infrared anti-collision module is detected itself and barrier by controller 8 Distance is compared with L1, and pyroelectric infrared sensor module is detected that itself is carried out at a distance from target drowning people with L2 Compare；When infrared anti-collision module itself is less than L1 at a distance from barrier, alarm module issues alarm sound, prompts behaviour Author pays attention to keeping safe distance, and controller 8 controls sea life-saving device auto-steering avoidance, does not otherwise alarm, sea is rescued Generating apparatus is navigated by water by original direction；Once pyroelectric infrared sensor module detects that itself is small at a distance from target drowning people When L2, alarm module issues alarm sound, prompts operator to notice that target drowning people can rescue in distance, does not otherwise report It is alert.

As shown in fig. 6, the lifesaving method is carried out by following below scheme:

S1: after operator witnesses drowning people, aboard ship taking out rapidly the sea life-saving device, by 1 set of the sheath body On a lifebuoy, the sea life-saving device is installed on the lifebuoy, presses switch button, then by the lifebuoy Together with the sea life-saving device throwing to sea；

S2: operator produces diffusing reflection with target drowning people using the laser pen prolonged exposure target drowning people on ship The raw light being detected enough；

S3: it if laser diffusion receiver array 4 receives the optical signal that diffusing reflection generates with target drowning people, controls The electric signal that device 8 processed is sent according to laser diffusion receiver array 4 judges the orientation of target drowning people, and the orientation is set It is set to direction of advance, control power plant module 7 drives sea life-saving device to navigate by water by direction of advance；

If laser diffusion receiver array 4 is not received by the optical signal that diffusing reflection generates with target drowning people, Controller 8 controls power plant module 7 and drives sea life-saving device rotation or navigate by water by arbitrary orientation, until laser diffusion receives Device array 4 searches the orientation of target drowning people；

S5: opening four infrared anti-collision modules, detects the barrier on sea life-saving device periphery, it is red to open four pyroelectricities Outer sensor module detects the infrared signal on sea life-saving device periphery；

S6: if infrared anti-collision module detects itself is more than or equal to L1 at a distance from barrier, controller controls power Module 7 drives sea life-saving device to navigate by water by direction of advance；

If infrared anti-collision module detects itself is less than L1 at a distance from barrier, while pyroelectric infrared sensor module Detect infrared signal, then 8 disturbance in judgement object of controller is drowning people, and controls power plant module 7 and drive sea life-saving device past It navigates by water in the direction of drowning people；

If infrared anti-collision module detects itself is less than L1 at a distance from barrier, while pyroelectric infrared sensor module Do not detect infrared signal, then controller 8 controls power plant module 7 and drives sea life-saving device bypass barrier, then by advance Direction navigation, until infrared anti-collision module detects itself is less than L1 at a distance from barrier, and pyroelectric infrared sensor mould Block detects infrared signal；

S8: sea life-saving device arrives at target drowning people position, searches and rescues successfully, terminates this process, otherwise return to Step S2 repeats this process.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.
