Throwing type floating alarm device for navigation

Abstract

The invention discloses a throwing type floating alarm device for navigation, and belongs to the field of navigation alarm devices. The throwing type floating alarm device for navigation is characterized in that when the alarm device works normally, signals emitted by a plurality of signal transmitting devices are transmitted to a signal amplifying device and are transmitted after being enhanced by the signal amplifying device, compared with an alarm device with a single signal transmitting device, the signal amplifying device is used for integrally transmitting the signals of the signal transmitting devices, so that the failure of the alarm device caused by the failure of the single signal transmitting device can be avoided, and the reliability of the alarm device is improved. Meanwhile, the alarm signal can be enhanced, the probability that the alarm signal is searched by a low-altitude searching helicopter or other searching equipment is increased, the searching helicopter finding the alarm device can roughly estimate the position of a wrecked ship according to the position of the alarm device and hydrological data, the searching range is narrowed, and the searching success rate is increased.

Description

technical field [0001] The invention relates to the field of navigation warning devices, and more specifically, relates to a throw-in type floating warning device for navigation. Background technique [0002] Navigation accidents are damages caused by the ship during navigation due to errors in command and control and navigation operations, failure of mechanical devices, severe sea conditions, or other man-made, equipment, natural and unknown reasons. Such as collision, grounding, grounding, shipwreck and other accidents. [0003] With the development of communication technology, satellite phones can be used to communicate with roadbed bases during navigation. When accidents occur during ship navigation, satellite phones can be used to communicate with roadbed poles in time to arrange rescue activities in time. However, in some extreme In bad weather, the communication quality of the satellite phone will also be affected, and it is impossible to get in touch with the land b...

[0003] With the development of communication technology, satellite phones can be used to communicate with roadbed bases during navigation. When accidents occur during ship navigation, satellite phones can be used to communicate with roadbed poles in time to arrange rescue activities in time. However, in some extreme In bad weather, the communication quality of the satellite phone will also be affected, and it is impossible to get in touch with the land base, so the land base needs to send search planes or use remote sensing satellite memory to search

[0004] However, due to the large ocean area, searching for the wrecked ship alone is tantamount to finding a needle in a haystack, even though the staff can roughly estimate the drifting position of the ship based on the location of the ship before it lost contact and the meteorological factors such as the ocean current in the area where the ship is located , greatly increasing the success rate of searching for wrecked ships, but once the search takes too long, it is very easy to cause casualties in the wrecked ship, leading to safety accidents
