Information transmission system applied to outdoor emergency rescue and application method thereof

Abstract

The invention discloses an information transmission system applied to outdoor emergency rescue. The information transmission system is a user equipment terminal used for sending rescue information at outdoors, and comprises a first information routing assembly. The first information routing assembly comprises a first input module for receiving the rescue information input by users, a first modulation module for transforming the rescue information input by the users into first pulse modulation information, a first laser emission module for sending corresponding first pulse laser signals on the basis of the transformed first pulse modulation information, and an information receiving terminal for receiving the pulse laser signals, and the information receiving terminal comprises a first demodulation module. The information transmission system applied to the outdoor emergency rescue can transmit detailed information of the danger and rescue to the outside in a reliable, fast and no-dead-angle way when the common means of communication loses effect, is favorable for a rescue unit to obtain the information timely through the system and reasonably arrange the rescue activities, and has better adaptability and practicability.

Description

technical field [0001] The invention relates to a transmission method for distress information used in outdoor rescue situations. More specifically, the present invention relates to an information transmission system for outdoor emergency rescue in the absence of communication signals. Background technique [0002] The current outdoor emergency rescue methods mainly include the following three types: one is the mobile phone communication with GPS, which can be used in areas covered by mobile phone signals, and mainly transmits the distress information by sending text messages or calling, but this method has disadvantages The reason is that there is nothing you can do where there is no mobile phone signal; the second is the hand-held walkie-talkie, which can realize calls within several kilometers, but in places with rugged terrain such as mountains, the call distance and effect will be greatly reduced, and it is impossible to achieve no dead ends. The third is satellite pho...

[0002] The current outdoor emergency rescue methods mainly include the following three types: one is the mobile phone communication with GPS, which can be used in areas covered by mobile phone signals, and mainly transmits the distress information by sending text messages or calling, but this method has disadvantages The reason is that there is nothing you can do where there is no mobile phone signal; the second is the hand-held walkie-talkie, which can realize calls within several kilometers, but in places with rugged terrain such as mountains, the call distance and effect will be greatly reduced, and it is impossible to achieve no dead ends. The third is satellite phone, such as the Iridium Global Star (global range) of the United States, Asia Star (only most of Asia), Eurostar (most of the world), Maritime Satellite (most of the world) and other systems, which belong to different The price of the operator is relatively expensive, and the usage fee is relatively high. The Beidou box based on the Beidou satellite is also this kind of satellite communication equipment. Its price is slightly lower, but it can only send location information to the set number, and the amount of information is very large. Small, and the way to call for help is not direct
