Beidou emergency call method and system

Abstract

The embodiment of the invention provides a Beidou emergency call method. The Beidou emergency call method comprises the steps that: an external terminal interacts with the outside to generate a call request signal, and sends the call request signal to a Beidou terminal that is in a near field communication connection with the external terminal; the Beidou terminal triggers to obtain the position information and a Beidou ID of the Beidou terminal according to the received call request signal, and sends the position information and the Beidou ID to the external terminal; the external terminal further interacts with the outside to generate user-defined help information; the external terminal compresses the position information and the Beidou ID, and sends the compressed position information and the Beidou ID to the Beidou terminal together with the help information; and the Beidou terminal sends the compressed position information and the Beidou ID to a central rescue server together with the help information through the Beidou satellite. The embodiment of the invention further provides a Beidou emergency call system. The Beidou terminal is manipulated by the external terminal, and more data are transmitted within the limit of fixed Beidou short message communication characters by compressing the compression characters.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of emergency call for help, in particular to a Beidou emergency call method and system. Background technique [0002] At present, most mobile phones or positioning devices on the market are equipped with BDS / GPS positioning functions, and some are equipped with base station positioning methods. In case of emergency, you can call for help from relatives, friends and relevant departments through mobile phones. This method is simple and effective in most cases, but when there is no mobile phone signal in some remote areas or harsh environments, it is impossible to send a distress signal. Some special industries, such as deep mountain forestry and fishery, need to be stationed in places without mobile phone signals for a long time. Unable to communicate with the outside world, people in distress cannot send an alarm in time in most emergency situations. [0003] In the existing technology,...

Problems solved by technology

This method is simple and effective in most cases, but when there is no mobile phone signal in some remote areas or harsh environments, it is impossible to send a distress signal. Some special industries, such as deep mountain forestry and fishery, need to be stationed in places without mobile phone signals for a long time. Unable to communicate with the outside world, and in most emergency situations, people in distress cannot send an alarm in time

[0003] In the existing technology, the Beidou satellite short-message communication function can be used to enable users to communicate with the outside world in places where there is no mobile network signal. In order to understand the situation of help-seekers in more detail, Beidou terminals are also equipped with keyboards, screens, etc. However, the human-computer interaction accessories will consume a lot of power in the process of human-computer interaction. When the power is exhausted, the help-seeker cannot use the Beidou terminal to call for help, which seriously reduces the need for help. the safety of the occupant;

[0004] In addition, the number of communication characters in a message sent by Beidou satellite short message communication is limited, and the content of the call for help requested by the caller cannot be sent out in a timely and complete manner, which seriously reduces the response to the call for help. timeliness of work
