Embodiment 1

[0054] Such as figure 2 The illustrated embodiment is a person falling into the water locating device, comprising a housing 21 made of non-conductive material, a GPS locator 1 disposed in the housing, a microprocessor 2, a memory 3, a Beidou positioning unit 4, a Beidou communication Unit 5, a rechargeable battery for power supply and a power switch 22, a key 23, a display screen 6 and a water drop switch 24 arranged on the housing; , the display screen, the key and the memory are electrically connected; the water drop switch includes two metal sheets 7 with a distance of 5 cm on the rear surface of the housing, one metal sheet is grounded, and the other metal sheet is connected to the micro by the wire passing through the casing. The processor is electrically connected. The metal sheet is a rectangular copper sheet, and the inner side of the metal sheet is bonded to the shell by waterproof glue.

[0055] Such as image 3 As shown, the Beidou positioning unit includes a po...

Embodiment 2

[0087] When the decrypted data information in Embodiment 2 also includes a cycle change instruction, the cycle change instruction includes a time interval value T1, and the microprocessor replaces T with T1.

[0088] When the decrypted data information also includes status inquiry information; the Beidou communication unit decrypts the status inquiry information, and the decrypted status inquiry information is displayed on the display; if the button is pressed within 4 minutes of the Beidou search and rescue device sending the data information, Then the Beidou communication unit sends confirmation information to the Beidou search and rescue device.

[0089] If no confirmation message is received 4 minutes after the Beidou search and rescue device sends the status inquiry message, the search and rescue personnel will make a judgment that the situation of the person who fell into the water is urgent.

[0090] Other structures and steps in Embodiment 2 are the same as those in Em...

Abstract

The invention discloses a positioning device and a positioning method for a drowning person. The device comprises a shell made from a nonconductive material, a GPS (global positioning system) positioning device, a microprocessor, a memory, a Beidou positioning unit, a Beidou communication unit, a rechargeable battery for supplying power, a power switch, a key, a display screen and a drowning switch, wherein the GPS positioning device, the microprocessor, the memory, the Beidou positioning unit, the Beidou communication unit and the rechargeable battery are arranged in the shell; the power switch, the key, the display screen and the drowning switch are arranged on the shell; the microprocessor is electrically connected with the Beidou positioning unit, the Beidou communication unit, the GPS positioning device, the power switch, the display screen, the key and the memory respectively; the drowning switch comprises two metal sheets which are arranged on the rear surface of the shell at an interval of more than 4cm; one metal sheet is grounded, and the other metal sheet is electrically connected with the microprocessor. The device and the method have the characteristics of capability of quickly positioning the drowning person, determining the current state of the drowning person, knowing information about the drowning person in detail, bringing convenience to the rescue planning of a rescue department and improving the rescue efficiency, high stability and high reliability.

Description

technical field [0001] The invention relates to the technical field of marine search and rescue, in particular to a reliable and stable personnel falling overboard positioning device and positioning method. Background technique [0002] Common life-saving devices use GPS positioning system or AIS system for positioning. When the GPS positioning system is controlled and interfered, the rescuers cannot find the person who fell into the water, and the GPS positioning system cannot transmit text data. Using the AIS system has the disadvantage of short transmission distance. [0003] Chinese Patent Authorization Publication No.: CN102284152A, the authorized publication date is December 21, 2011, which discloses an AIS lifesaving positioning indicator for lifejackets, comprising: a columnar outer shell, a garment hook is arranged on the outer wall of the outer shell, There is a sealed lampshade on the upper part of the lampshade, and there is a high-brightness controllable LED in...
