[0039] figure 1 The basic flow chart of the distance detection method provided in this embodiment is used for receiving equipment, and the distance detection method includes:

[0040] S101. Receive first sound wave data and second sound wave data sent by a sending device at the same time, where the propagation rates of the first sound wave data and the second sound wave data are different.

[0041] S102. Determine an actual distance to the sending device according to the receiving time of the first sound wave data and the second sound wave data.

[0042] The method in this embodiment can be applied between the main detection device and the detected device. Among them, both the main detection device and the detected device can send sound wave data, and have the function of sound wave reception and identification. During the specific implementation process, the main detection device and the detected device can be used as both the sending device and the receiving device. For e...

[0060] The second embodiment of the present invention proposes a distance detection method for a sending device, including:

[0061] sending the first sound wave data and the second sound wave data to the receiving device at the same time, the first sound wave data and the second sound wave data have different propagation rates;

[0062] The first sound wave data and the second sound wave data are used for the receiving device to confirm the actual distance from the sending device according to the corresponding sound wave receiving time.

[0063] Optionally, sending the first sound wave data and the second sound wave data to the receiving device at the same time includes:

[0064] When the sending device is in the working mode, sending the first sound wave data and the second sound wave data to the receiving device at the same time according to a preset sending rule;

[0065] When the sending device is in sleep mode, after receiving the third sound wave data sent by the recei...

[0068] figure 2 The basic flowchart of the distance detection method provided in this embodiment, the distance detection method includes:

[0069] S201. The main detection device sends third sound wave data for waking up the sending device to the sending device, where the third sound wave data includes sound identification information.

[0070] Specifically, when the detected device is in a dormant state, after receiving the third sound wave data sent by the main detection device, the sound identification information in the third sound wave data is extracted for recognition. The data is thus awakened by the detection device, and then the first sound wave data and the second sound wave data are sent to the main detection device at the same time.

[0071] S202. The main detection device receives the first sound wave data and the second sound wave data sent by the detected device at the same time, where the first sound wave data and the second sound wave data have different pro...

Abstract

The invention discloses a distance detection method and device and a readable storage medium, and the method comprises the steps: receiving first sound wave data and second sound wave data sent by a sending device at the same moment, and enabling the propagation rates of the first sound wave data and the second sound wave data to be different; and determining an actual distance with the sending device according to the receiving time of the first sound wave data and the second sound wave data. First sound wave data and second sound wave data sent by sending equipment at the same moment are directly received; and according to the receiving time of the first sound wave data and the receiving time of the second sound wave data, the actual distance with the sending equipment is determined, so that the method realizes a positioning effect in a physical sound wave mode without consuming flow.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a distance detection method, device and readable storage medium. Background technique [0002] Existing technical solutions use a positioning system to determine the specific location of a positioned object, such as mobile phone navigation. However, most of the existing technical positioning solutions are based on satellite positioning systems, which need to consume user traffic and still have large errors in the accuracy of short-distance positioning. And when the satellite signal is weak, there may be a problem that the positioning cannot be used. Contents of the invention [0003] The technical problem to be solved by the present invention is to solve the problem of low precision in short-distance distance detection. Aiming at this technical problem, a distance detection method, device and readable storage medium are provided. [0004] In order to so...
