Embodiment 1

[0112] The embodiment of the present application provides a method for determining the distance change, which is used to solve the problem that the users cannot determine the distance change between each other using the existing positioning technology when the distance between two positioning users is small. The flow chart of the method is shown in figure 1 As shown, the method specifically includes the following steps:

[0113] Step 11: The receiving end collects the sound wave signal of the preset frequency sent by the sending end.

[0114] In the step, the frequency of the sound wave signal sent by the sending end is a preset frequency, and the frequency can be: when the sending end receives a request for sending the sound wave signal, the request contains the information of the receiving end, and the system is the sending end and the receiving end. assigned frequency. It may also be that the sending end and the receiving end first establish a pairing relationship, and then...

Embodiment approach

[0160] In the first embodiment, after the receiving end generates the prompt information, the prompt information is directly sent to the sending end, so as to remind the user holding the sending end of the change in the distance between the sending end and the receiving end.

[0161] In the second implementation manner, after the receiving end generates the prompt information, it first sends the prompt information to the server, and then the server sends the prompt information to the sending end.

[0162] In the third embodiment, the sending end can also generate prompt information according to the energy of the sound wave signal. The specific method is: after the receiving end collects the sound wave signal sent by the sending end, the sending end receives the sound wave signal returned by the receiving end. Information, which can be the frequency, wavelength, energy or amplitude of the acoustic signal. The following still uses "energy" as an example to illustrate the process...

Embodiment 2

[0182] Embodiment 1 provides a method for determining the distance change. Correspondingly, the present application also provides a device for determining the distance change, which is also used to solve the problem that when the distance between two positioning users is small, the user cannot use the existing positioning technology. The problem of determining changes in distance from each other. The device is located in the receiving end, and the specific structure is as follows Figure 8 shown, including the following units:

[0183] The first acquisition unit 81 and the first determination unit 82, wherein:

[0184] The first collection unit 81 collects the sound wave signal of the preset frequency sent by the sending end;

[0185] The first determination unit 82 determines the change of the distance between the sending end and the receiving end according to the collected acoustic wave signal.

[0186] The specific working process of the device is as follows: first, the ...

Abstract

The present application discloses a method for determining distance change, a position prompting method, and a device and system thereof. The method for determining the distance change includes: the receiving end collects the acoustic wave signal of the preset frequency sent by the transmitting end; and according to the collected acoustic wave signal, determining the distance change between the transmitting end and the receiving end. Compared with the positioning method in the prior art, the method for determining the distance change provided by the present application can also determine the distance change between the two ends when the positioning distance between the sending end and the receiving end is relatively small. The present application can also generate corresponding prompt information according to the change of the distance between the two ends. The prompt information is used to prompt the user to change the distance between the two ends, and to guide the user to move in the direction of decreasing the distance between the two ends. Compared with the existing When the distance between the two positioned users is small, the probability of finding each other by applying the method provided in this application increases.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a method for determining distance changes, a location prompting method, and a device and system thereof. Background technique [0002] With the vigorous development of science and technology, positioning technology is widely used in users' lives. For example, if a user installs a positioning tracker in a car, when the car is stolen, the user can know the specific location of the car according to the positioning tracker, which is convenient The user makes a lookup, and so on. [0003] At present, the commonly used positioning methods include GPS positioning and LBS positioning. Among them, GPS positioning mainly relies on satellite navigation system to locate the target; CDMA network), or use GPS positioning to locate mobile terminal users. [0004] Usually, the error of obtaining the location information of the target user by GPS positioning is about 4 to 5 me...
