Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] see figure 1 , the present invention includes a control unit module, a Beidou communication module, a detection and early warning module, an input and output module and a power supply module.

[0031] Power-on and device initialization. There are two ways to power on and start. One is self-triggering. After the water sensor detects falling into the water, the device will be powered on and started, and the alarm signal will be sent to the control unit module periodically, and the LED warning light will start to flash at the same time; One way is to start manually, that is, to start the search and rescue positioning terminal through a programmable button, the terminal is powered on and performs and completes the self-inspection work, and the terminal device supports one-button reset.

[0032] During the self-triggering process of falling-in-water detec...

Abstract

The invention discloses a maritime search and rescue positioning terminal based on Beidou satellite communication, and the terminal automatically gives an alarm when a person falls into water or a ship is in distress. The ship name, personal information, position, time and other help seeking information are automatically sent to a search and rescue center server through the Beidou satellite according to a set period and displayed on an electronic chart, and a search and rescue center can timely organize recent search and rescue power for search and rescue after checking the dangerous situation. The positioning and communication functions of the terminal are completed based on a Beidou communication satellite, domestic autonomous controllability is realized, and the communication safety is guaranteed; in the alarm information sending and receipt receiving process, two-way transmission of search and rescue signals is achieved, and the rescue efficiency is improved; two power-on modes of alarm self-starting and manual starting can be adopted. The system is stable and reliable. The indicating lamp can display the information receiving receipt and flicker to prompt the position of a person, and functions are rich. And the equipment adopts a miniaturized design and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of communication and information systems, in particular to water positioning search and rescue equipment based on Beidou satellite communication. Background technique [0002] With the rapid development of shipping, the importance of emergency search and rescue of ships in distress has become increasingly significant, and obtaining ship distress alarm information and its location in the shortest time has become a key element to improve the success rate of search and rescue. In addition to using the low-polar orbit search and rescue satellite system (COSPAS-SARSAT), our country is also vigorously promoting the ship emergency search and rescue system based on the short message communication of the Beidou satellite navigation system. With the official completion of the network operation of the Beidou-3 global system in 2020, Expand the service area from the Asia-Pacific region to the world, and comprehensively ...
