Embodiment 1

[0044] The first embodiment of the present invention proposes a mobile terminal for post-disaster search and rescue, its structure is as follows figure 1 shown, including:

[0045] Passive control module 1 and / or active control module 2;

[0046] The passive control module 1 is used to receive a preset control signal, and to establish an emergency link connection with a remote device, to control the mobile terminal to switch to an emergency control mode; it is also used to detect the ambient temperature, and judge according to the temperature Whether there is life; and the judgment result is sent to the remote device;

[0047] The active control module 2 is configured to switch the mobile terminal to an emergency control mode according to user input, and establish an emergency link connection with the remote device;

[0048] The mobile terminal also includes:

[0049] A distress signal sending module 3, configured to generate a distress signal according to preset rules, and...

Embodiment 2

[0055] The second embodiment of the present invention proposes a mobile terminal for post-disaster search and rescue, which is improved on the basis of the aforementioned first embodiment, including:

[0056] an active control module and / or a passive control module;

[0057] The passive control module is used to receive a preset control signal, and to establish an emergency link connection with the remote device, to control the mobile terminal to switch to the emergency control mode; it is also used to detect the ambient temperature, and judge whether to alive; and send the judgment result to the remote device;

[0058] The active control module is configured to switch the mobile terminal to an emergency control mode according to user input, and establish an emergency link connection with the remote device;

[0059] The mobile terminal also includes:

[0060] A distress signal sending module, configured to generate a distress signal according to preset rules, and transmit it...

Embodiment 3

[0065] The third embodiment of the present invention proposes a life detector, its structure is as follows: figure 2 shown, including:

[0066] A signal receiving module 11, configured to receive a distress signal sent by the mobile terminal;

[0067] The positioning module 12 is configured to send a positioning control signal, and calculate the time delay of the received positioning signal sent by the mobile terminal.

[0068] The embodiment of the present invention proposes a life detector, which is used to receive the distress signal actively sent by the mobile terminal, and despread and coherently demodulate the distress signal according to the preset rules, so as to obtain the mobile phone number in the distress signal or other mobile terminal identifiers. After the survivors are found, triangulation can be performed through the time delay values ​​tested by three or more life detectors, so as to accurately locate the survivors and improve the search and rescue efficie...

Abstract

The invention provides a mobile terminal, a life detection instrument, a post-disaster search and rescue system and a post-disaster search and rescue method. The mobile terminal can be switched to an emergency control mode by an active and / or passive mode(s) and positioned by the life detection instrument by a three-point or multi-point positioning mode. The method comprises the following steps of: establishing an emergency link connection between the mobile terminal and the life detection instrument and switching the mobile terminal to the emergency control mode; generating a distress signal by the mobile terminal according to a preset rule, spreading a spectrum by using a spectrum spreading code and transmitting the signal to the life detection instrument, wherein the distress signal at least comprises a unique identifier of the mobile terminal; transmitting a positioning control signal to the mobile terminal after the life detection instrument receives the distress signal; transmitting a positioning signal by the mobile terminal; and calculating the position of the mobile terminal according to time delay of the positioning signals received by three or more life detection instruments arranged around the mobile terminal. The embodiment of the invention can also realize accurate positioning to improve the search and rescue efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mobile terminal, a life detector, a post-disaster search and rescue system and method. Background technique [0002] Natural disasters have the characteristics of instantaneous occurrence, severe damage, difficult monitoring and forecasting, and far-reaching social impact. For example, destructive disasters such as earthquakes and landslides have caused huge harm and losses to the country's economic construction and the safety of people's lives and properties. Numerous cases of natural disasters at home and abroad have proved that the level of post-disaster emergency rescue technology is extremely important for reducing disaster losses. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: [0004] At present, our country is still very weak in disaster emergency rescue technology, main...
