Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific examples.

[0021] The invention provides a sonar life locating device, such as figure 1 and figure 2 As shown, it includes at least 3 detectors 1 for being arranged on the shipwreck shell 2, each detector 1 includes a passive sonar 1-2; the output ends of the passive sonar 1-2 are respectively connected to the data processor 3; The data processor 3 is used to obtain the position coordinates of the life support call by using a geometric algorithm according to the coordinates of the detector and the time difference when the passive sonar 1-2 receives the call for life support signal.

[0022] In this embodiment, each of the detectors includes a housing 1-1, and the passive sonar 1-2 is arranged in the housing 1-1, and the housing 1-1 is provided with a The suction cup 1-3 is provided with a shock absorbing structure 1-4 outside the housing 1-1.

[0023] Preferably, each detector 1 furt...

Abstract

The invention provides a sonar life positioning device comprising at least three detectors arranged on an outer shell of a capsized boat, each detector comprises a passive sonar device, and an output end of each passive sonar device is connected with a data processor; according to the coordinates of the detectors and time difference of life help seeking signals received by passive sonar devices, the processor is used for obtaining coordinates of life help seeking positions via geometric algorithms. According to the sonar life positioning device and the sonar positioning method that are disclosed in the invention, time difference of sound transmission is used for positioning sound sources via geometric calculation, the life help seeking positions can be rapidly and effectively located, and therefore the positions of survivors can be confirmed; the device is simple in structure and can be directly absorbed onto the outer shell of the capsized boat, and convenience of operation and detection can be realized; the method is simple and requires short processing time.

Description

technical field [0001] The present invention is a positioning device and a sonar positioning method capable of confirming the position of a survivor in a ship accident. Background technique [0002] At present, in a shipwreck accident, the survivors in the cabin send distress signals to the outside world by shouting and knocking, while the traditional method is to confirm the location of the survivors by listening close to the hull and receiving such distress signals with a stethoscope. Obviously, this search and rescue method has great shortcomings. First, it cannot locate quickly, and in an accident, time is undoubtedly precious; second, it cannot locate accurately, which increases the difficulty of search and rescue work. Contents of the invention [0003] In order to overcome the shortcomings of traditional search and rescue methods that are difficult to locate and can not quickly implement search and rescue measures, the present invention designs a sonar life locating...
