Problems solved by technology

[0004] In addition, the cost of the above-mentioned electronic products is not cheap, and it is impossible for everyone to carry them; the electronic devices that need to be carried by rescuers need additional power supply, and there is a problem of energy depletion. If the energy is depleted, the ground search and rescue system will not be able to receive them. Signal ， It will directly lead to a great reduction in search and rescue efficiency; in addition, in mine disasters, if the gas concentration is too high, a certain current may cause an explosion

Embodiment 1

[0032] Embodiment 1: self-service passive life calling method, such as figure 1 shown, including the following steps:

[0033] S1, receiving mid-high frequency search and rescue signals with adjustable strength and converting them into electrical energy, among which the strength of mid-high frequency search and rescue signals can be adjusted manually, wired or wirelessly according to different environments, so as to ensure the wide range of search and rescue measurements carried out by search and rescue personnel , not limited by the environment; the energy conversion described above can be realized by a filtering device and an energy harvesting device, and the filtering device only converts mid-high frequency search and rescue signals of a specified frequency band into electrical energy during energy conversion, while filtering out other mid-high frequency signals, It is guaranteed to start working only when there is a search and rescue signal, which ensures a more targe...

Embodiment 2

[0036] Embodiment 2: realize a kind of self-service passive life-saving system of above-mentioned method, as figure 2 As shown, it includes: a search and rescue signal transmitter, an energy conversion module, an activation module, a distress signal generation module and a distress signal recognition locator, the activation module is respectively connected with the energy conversion module and the distress signal generation module, and the energy conversion module is wirelessly connected to the search and rescue signal transmission machine, and the distress signal generation module is wirelessly connected to the distress signal identification and locator. The search and rescue signal transmitter and distress signal identification and locator are called an above-ground search and rescue system; the energy conversion module, activation module and distress signal generation module are called an underground distress system. The energy conversion module includes a filter device ...

Embodiment 3

[0037] Embodiment 3, application example: a self-service passive life-saving system, including: a search and rescue signal transmitter, an energy conversion module, an activation module, a distress signal generation module and a distress signal identification locator, and the activation module is connected with the energy conversion module and the distress signal recognition locator respectively. The distress signal generation module is connected, the energy conversion module is wirelessly connected to the search and rescue signal transmitter, and the distress signal generation module is wirelessly connected to the distress signal identification and locator.

[0038] Wherein, the search and rescue signal transmitter can be realized by a signal generator chip and an antenna, and the antenna can be an antenna with a matching impedance of 50 ohms. The search and rescue signal transmitter further includes: a power amplifier, which can greatly shorten the energy conversion time o...

Abstract

The invention discloses a self-service passive life-calling method and system. The method includes the following steps: S1, receiving mid-frequency search and rescue signals with adjustable intensity and converting them into electric energy; S2, triggering the generation of the calling-for-help signals manually or automatically The module generates a medium and high frequency distress signal; S3, seamlessly captures the medium and high frequency distress signal and determines the position and distance of the person in need of rescue. The present invention is based on medium and high-frequency signals. Compared with the existing search and rescue methods, the search and rescue measurement range can be expanded, so that the search and rescue will not be affected by the post-disaster environment, and the measurement accuracy and search and rescue efficiency are greatly improved; in addition, the call for help module in the present invention does not need Additional power supply and strong explosion-proof capability; in addition, in the present invention, according to different vital signs signals, searchers and rescuers can rationally allocate personnel to search and rescue survivors with poor vital signs so as not to delay the best treatment time, and finally achieve the goal of saving time when every second counts. Search and rescue the scene to save more lives.

Description

technical field [0001] The invention relates to a self-service passive life calling method and system, and belongs to the technical field of communication. Background technique [0002] In recent years, affected by factors such as extreme weather, earthquakes and engineering construction, various natural disasters have caused heavy casualties and property losses to human beings. Since the technical level of post-disaster emergency search and rescue is extremely important for reducing disaster losses, improving and perfecting the disaster relief system has received extensive attention from various countries. [0003] At present, there are mainly four types of search and rescue systems put into use at home and abroad: optical type, audio type, infrared type, and radar type. The optical search and rescue system uses a metal snake tube that can be bent arbitrarily so that the lens at the front can observe the situation under the ruins through the gaps in the ruins of the buildi...
