Problems solved by technology

[0003] However, sometimes there will be an embarrassing phenomenon: when donkey friends travel into the mountains, the people behind them often cannot keep up with the guides, and they cannot describe their location clearly when calling. The network signal or satellite signal from the base station cannot be received
In addition, it often happens that after entering the mountain, the way out of the mountain cannot be found, which leads to getting lost. 3. Rescue is required
Donkey friends or college students travel to the mountains, and the incidents of getting lost or unable to return are often reported in the newspapers. They basically have smart mobile terminals in their hands, but they fail to play a greater role. It is really "heroes are useless."
[0004] Aiming at the problem that the function of the mobile terminal is not perfect enough in related technologies, no effective solution has been proposed yet

Embodiment 1

[0040] In this preferred embodiment, a distance determination method based on an ad hoc network is provided, and the method is described by taking the ad hoc network and the distance determination method of a handheld smart terminal as an example. Specifically, through the client, create a wifi-based network, calculate the relative physical distance through the attenuation of the wifi signal, and solve the problem of inability to determine the location information of members in areas that cannot be covered by wireless base stations.

[0041] The core of the method for calculating the relative physical distance based on the self-organizing network provided in this preferred embodiment is to use the attenuation of the wifi signal to calculate the relative physical distance and the security alarm method based on the distance.

[0042] The specific method for calculating the relative physical distance by using signal attenuation may be as follows: first, select a terminal A device ...

Embodiment 2

[0049] In this preferred embodiment, by installing the program in the smart client, the record of position, direction coordinate information, and travel route information is realized, and the recorded information is synchronized to other members in the network. its path to travel. Or follow the recorded path back to the starting point. image 3 is a schematic diagram of the execution flow according to Embodiment 2 of the present invention, such as image 3 As shown, the execution process of this preferred embodiment may include the following steps:

[0050] Step S302, firstly, client software needs to be installed in all smart terminals that need to build a network.

[0051] The client software implements the following functions:

[0052] Function 1: Establish an ad hoc network and add members. In this way, the establishment of the network and the addition of members in the group can be realized.

[0053] Function 2: Record information such as location information, direct...

Abstract

The invention discloses a ranging method and a ranging device. The ranging method comprises the following steps: a first mobile terminal receives a signal, set as a hot point, of a second mobile terminal; and the first mobile terminal acquires a first distance between the first mobile terminal and the second mobile terminal according to the signal strength of the received signal. With the ranging method and the ranging device, the problem that mobile terminals are not fully functional in the related technology is solved, locating operation under the situation in which an external network cannot be received is realized, and the user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a ranging method and device. Background technique [0002] With the improvement of people's living standards, self-driving tours, cycling tours, group tours, etc. enrich people's spare time life, more and more people participate in it, and occupy an increasingly important position in people's daily life. At the same time, with the development of the mobile communication industry, especially the popularization of the third generation (3G for short) and fourth generation (4G for short) communication, smart mobile terminals (such as smart phones) also enter popularization stage. [0003] However, sometimes there will be an embarrassing phenomenon: when donkey friends travel into the mountains, the people behind are often unable to keep up with the guides, and they cannot describe their location clearly on the phone. The network signal or satellite signal from the base station can...
