Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of positioning and search and rescue, and particularly relates to a multi-mode personal positioning and search and rescue beacon. BACKGROUND

[0002] The multi-mode personal positioning and search and rescue beacon is a portable emergency device designed for a single person or a small group. The core function is to send location information and distress signals to the outside world through multiple positioning technologies and communication modes when the user encounters danger (such as getting lost in the wild, being in distress at sea, industrial accidents, etc.), assisting the search and rescue team to quickly locate and implement rescue. Compared with traditional single-mode beacons (such as relying only on satellite positioning), the multi-mode characteristic is reflected in the integration of satellite, ground communication, and short-range sensing technologies, which can adapt to complex environments (such as deep mountains, oceans, urban high-rise buildings, tunnels, etc.), ensuring that the positioning and communication capabilities are maintained when a single mode fails, greatly improving the success rate of search and rescue.

[0003] In special scenarios such as outdoor exploration, marine operations, and geological exploration, personnel are often lost or in distress. Efficient personal positioning and search and rescue technology is crucial to ensuring life safety. Currently, personal positioning and search and rescue beacons, as important lifesaving equipment, have been widely used in various high-risk environments. The core function is to transmit the location information of the distressed personnel to the outside world through a specific signal transmission mechanism, assisting the search and rescue forces to quickly locate the target.

[0004] However, existing multi-mode personal positioning and search and rescue beacons mostly use a relatively simple structure, which can provide high accuracy in general cases, but in satellite signal blocked areas such as dense forests, canyons, and urban high-rise buildings, people need to constantly change the search and rescue direction of the beacon to obtain stronger signals for transmission or reception of positioning data. Long-time operation can cause arm fatigue and may cause positioning signal interruption, resulting in inaccurate or untransmitted location information. Such beacons will be completely ineffective and unable to function.

[0005] Due to the above limitations, it is difficult to quickly and effectively adapt to actual distress situations. If the signal direction transmission is not good, feedback information from the search and rescue side cannot be received, and the distressed person cannot know whether their signal has been received or not, and cannot adjust the signal transmission strategy according to the progress of the search and rescue, making it more dangerous. Therefore, the present application proposes a multi-mode personal positioning and search and rescue beacon. SUMMARY
