Background technique

With the advancement of science and technology, various kinds of anti-lost products came into being in order to enable people to manage items conveniently and reliably and avoid loss. Among many anti-lost products, anti-lost devices, especially radio anti-lost devices, are popular among the public because of their wide range of uses.

The radio anti-lost device obtains the location change of the managed device through a wireless signal, and sends an alarm message to the device manager (such as the user's smart terminal) in time to avoid the loss of the device.

In different scenarios, based on the state of the anti-lost device control terminal and/or the anti-lost device terminal or its position change with the movement of people or objects, the positioning and prevention of the anti-lost device terminal can be achieved in various ways Lost control. The positioning solution and the anti-lost control solution of the anti-lost device terminal of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.

Anti-lost device terminal positioning

FIG. 1 shows a schematic flowchart of a method for locating an anti-lost device terminal according to an embodiment of the present disclosure. As an example of the present disclosure, the positioning method may be implemented by a module capable of performing object-finding navigation and positioning calculation, and the module may be deployed on a server or a specific anti-lost device server, or on an intelligent control device. In the following example, the server is used as the main body of the positioning method for explanation.

As shown in FIG. 1, in step S110, in response to the first anti-lost device terminal positioning request sent by the first anti-lost device control terminal, the second anti-lost device control terminal is sent to measure the second anti-lost device control terminal and A distance measurement instruction of the distance between the first anti-lost device terminals.

Among them, the first or second anti-lost device control terminal can be connected to the server in a wireless communication manner (such as an Internet communication network), and the first or second anti-lost device control terminal can also be connected to the first anti-lost device The terminal communicates through wireless communication. The wireless communication methods may include, but are not limited to, LoRa, Bluetooth, ultra-wideband, ZigBee, and Wi-Fi, etc., which are not limited in this disclosure.

As an example of the present disclosure, the first anti-lost device control terminal may be an anti-lost device control terminal associated or bound to the first anti-lost device terminal, and the second anti-lost device control terminal may be the first anti-lost device control terminal Other than the control terminal of the anti-lost device. As an example of the present disclosure, for example, the anti-lost device control terminal and its associated anti-lost device terminal may be implemented by associatedly recording the anti-lost device control terminal and its associated anti-lost device terminal in the server's association table during the registration phase. Association or binding.

When the first anti-lost device control terminal is relatively close to the associated first anti-lost device terminal, the first anti-lost device control terminal may communicate with the first anti-lost device terminal via Bluetooth, for example, and may realize Positioning of the first anti-lost device terminal.

When the first anti-lost device control terminal cannot locate the first anti-lost device terminal, the first anti-lost device control terminal may, for example, send the first anti-lost device terminal positioning request to the server through the Internet communication network. The first anti-lost device terminal positioning request may include the first position information of the first anti-lost device control terminal and the anti-lost device terminal identification information of the first anti-lost device terminal (such as the name, logo or Communication physical address, etc.).

In a preferred embodiment, when the server receives the positioning request of the first anti-lost device terminal, it may search the record in the above-mentioned association table to determine whether the control terminal of the first anti-lost device is in contact with the first anti-lost device terminal Associated or bound. In other words, it can be determined whether the control terminal of the first anti-lost device has the right to obtain the position of the first anti-lost device terminal.

In addition, in a preferred embodiment, when the first anti-lost device terminal positioning request includes the first position information of the first anti-lost device control terminal, the server may determine one or more of the first anti-lost device terminals nearby The control terminal of the second anti-lost device to send the ranging instruction to it. When the control terminal of the first anti-lost device finds that the associated first anti-lost device terminal cannot be located, it is often not far from the first anti-lost device terminal. In this case, the control terminal of the second anti-lost device near the control terminal of the first anti-lost device can often achieve a more accurate ranging to the terminal of the first anti-lost device.

When sending the ranging command to the second anti-lost device control terminal, the anti-lost device terminal identification information of the first anti-lost device terminal may be sent in association with the ranging command, so that the second anti-lost device terminal can be based on the The identification information of the anti-lost device terminal determines the first anti-lost device terminal, and then the distance between the terminal and the first anti-lost device terminal is measured.

In response to the received ranging instruction, the second anti-lost device controller can measure the distance between it and the first anti-lost device terminal through wireless ranging technology, and can return the measured value to the server through the Internet communication network The second distance data between the second anti-lost device control terminal and the first anti-lost device terminal and the second position information of the second anti-lost device control terminal.

Subsequently, in step S120, based on the second distance data between the second anti-lost device control terminal and the first anti-lost device terminal returned by the second anti-lost device control terminal and the second anti-lost device The second position information of the control end of the device determines the position of the first anti-lost device terminal.

The second distance data may be a specific second distance between the control terminal of the second anti-lost device and the first anti-lost device terminal (for example, the distance is XXX meters, YYY kilometers), or it may refer to Other data related to the second distance (such as communication time data).

The determined position of the first anti-lost device terminal may refer to a range of locations where the first anti-lost device terminal is located, or may refer to a specific geographic location of the first anti-lost device terminal.

Therefore, the positioning of the first anti-lost device terminal is realized based on the positions of other anti-lost device control terminals that are not associated with the first anti-lost device terminal and the distance from the first anti-lost device terminal, which is greatly reduced The positioning range of the anti-lost device terminal can improve the search efficiency of the anti-lost device terminal.

In addition, the anti-lost device terminal of the present disclosure can also communicate with a server or other anti-lost device terminal in a wireless communication manner.

As an example of the present disclosure, in response to the first anti-lost device terminal positioning request sent by the first anti-lost device control terminal, the server may also send the second anti-lost device terminal to measure the second anti-lost device terminal and the A distance measurement instruction for the distance between the first anti-lost device terminals, and may be based on third distance data between the second anti-lost device terminal and the first anti-lost device terminal returned by the second anti-lost device terminal And the third position information of the second anti-lost device terminal, to determine the location of the first anti-lost device terminal. The second anti-lost device terminal may be an anti-lost device terminal associated with the second anti-lost device control terminal.

As an example of the present disclosure, in response to the received ranging instruction, the second anti-lost device control end may also instruct a second anti-lost device terminal associated therewith to measure the second anti-lost device terminal and the first anti-lost device terminal The distance between the terminals, and the third distance data between the second anti-lost device terminal and the first anti-lost device terminal obtained by the measurement can be returned to the server through the Internet communication network. That is, the server may send a distance measuring instruction to measure the distance between the second anti-lost device terminal and the first anti-lost device terminal to the second anti-lost device terminal via the second anti-lost device control terminal.

Preferably, in the case where the position of the second anti-lost device terminal is known (it may be determined based on the positioning method of the present disclosure or may be determined by other means, the present disclosure does not limit this), the second anti-lost The controller end may also return the position information of the second anti-lost device terminal, that is, the third position information, to the server.

Thereby, the server may implement positioning of the first anti-lost device terminal based on the received second distance data and second location information and/or third distance and third location information.

After that, the determined location information of the first anti-lost device terminal may also be sent to the first anti-lost device control terminal, so that the administrator on the side of the first anti-lost device control terminal can target the first anti-lost device The device terminal locates and/or navigates to quickly and accurately find the anti-lost device terminal.

Therefore, through the above anti-lost device positioning solution, the position range or the precise position of the first anti-lost device terminal can be determined, so that the user on the control side of the first anti-lost device can quickly search for the first Anti-lost device terminal, improve search efficiency.

Multi-point positioning

As an example of the present disclosure, the above second anti-lost device control terminal may be one or more, and the second anti-lost device control terminal may also be associated with one or more second anti-lost device terminals. In this way, based on the distance between the control terminal of one or more second anti-lost devices and the associated one or more second anti-lost device terminals and the first anti-lost device terminal, for example, a multi-point positioning method may be used, To achieve accurate positioning of the first anti-lost device terminal.

In the following example, taking the second anti-lost device control terminal mentioned above instructing the second anti-lost device terminal to measure the third distance data as an example, the multi-point positioning method of the present disclosure is used to implement the first anti-lost device terminal. To describe the positioning. It should be understood that the second anti-lost device terminal may also communicate with the server without going through the second anti-lost device control terminal, and obtain the measurement of measuring the third distance between the second anti-lost device terminal and the first anti-lost device terminal from the server Distance instruction and return the third distance data and/or third position information to the server, or other data related to determining the third distance data.

It should be understood that the multi-point positioning of the present disclosure is equally applicable to other examples as previously described. In other words, the present disclosure may use the distance data from the first anti-lost device terminal and the location information of the first anti-lost device control terminal returned by the first anti-lost device control terminal, or multiple other anti-lost device control terminals and/or Any combination of distance data and/or location information returned by other anti-lost device terminals achieves accurate positioning of the first anti-lost device terminal, and the disclosure does not limit this. Specifically, in the above step S110, a distance measurement instruction may be sent to one or more second anti-lost device control terminals. Further, in step S120, multiple points can be passed according to the second distance data and second position information and/or third distance data and third position information returned by the one or more second anti-lost device control ends The positioning method determines the position of the first anti-lost device terminal.

Among them, when there is only one second anti-lost device control terminal, it can be determined according to the second position information and second distance data and/or third position information and third distance data returned by the second anti-lost device control terminal The location range of the first anti-lost device terminal. For example, a circle centered on the position of the control terminal of the second anti-lost device and a radius of the second distance corresponds to two intersections of a circle centered on the location of the terminal of the second anti-lost device and the radius of the third distance s position.

And in the case where the control terminal of the second anti-lost device and the terminal of the second anti-lost device are close to each other, the second position and the third position can be approximately regarded as the same position, and the second distance and the third distance can be approximately regarded as The same distance. Therefore, the position of the first anti-lost device terminal determined above is a range of positions, that is, a circular area with the second position as the center and the second distance as the radius.

Thus, based on the first position information, the second position information, and the distances of the first anti-lost device terminal relative to the second anti-lost device control terminal and the second anti-lost device terminal, respectively, the relative position of the first anti-lost device terminal can be determined A relatively small position range at the control terminal of the first anti-lost device can greatly reduce the human search range of the manager of the first anti-lost device control terminal.

When there are two second anti-lost control terminals, according to the second position information and the second distance data, the third position information and the third distance data returned by the two second anti-lost devices, respectively, through more Point positioning method to determine a small position range where the first anti-lost device terminal may be located: the overlapping area of the circle or the intersection point of the circle determined based on the above position and distance (specifically based on the position information and distance data The relationship between is determined).

When there are three or more second anti-lost control terminals, the second position information and the second distance data, the third position and the The third distance data determines the precise position of the terminal of the first anti-lost device (the intersection of three or more circles) by a multi-point positioning method.

Therefore, by specifying the positions of other anti-lost device control terminals and their associated anti-lost device terminals and their respective distances from the designated anti-lost device terminal (ie, the first anti-lost device terminal), the designated anti-lost device is realized. The positioning of the terminal can greatly reduce the positioning range of the designated anti-lost device terminal, improve the search efficiency for the designated anti-lost device terminal, and facilitate the tracking and management of the first anti-lost device terminal by the first anti-lost device terminal.

As an example of the present disclosure, the control terminal of the first anti-lost device may also include a ranging module, through which the distance between the terminal and the first anti-lost device terminal may be measured. In the case where, for example, the distance between the control terminal of the first anti-lost device and the anti-lost device terminal is not too far, and the two can still communicate wirelessly to measure the distance between the two, the above-mentioned first anti-lost device terminal positioning request The first distance data between the control terminal of the first anti-lost device and the first anti-lost device terminal may also be included.

Thus, in step S110, when the first position information and the first distance data are known, a ranging instruction can be sent to the relevant second anti-lost device control terminal, and then, in step S120, it can be based on the first The distance data and the first position information, the second distance data and the second position information, and/or the third distance data and the third position information determine the position of the first anti-lost device terminal.

For example, when the first distance data and the first position information are known, a distance measurement instruction may be sent to a second anti-lost device control terminal near the first location, and then, combined with the second anti-lost device control The second distance data and second position information returned by the terminal, or the third distance data and third position information, determine the circle centered on the first position and the first distance as the radius to be the first of the first anti-lost device terminal For the position range, the circle with the second position as the center and the second distance as the radius is determined as the second position range of the first anti-lost device terminal, and the circle with the third position as the center and the third distance as the radius is determined as the first The third position range of an anti-lost device terminal can be determined as the first anti-lost device control by the overlapping area of the first position range, the second position range and the third position range or the intersection of the corresponding three circles End position range or its precise position point.

For another example, when the first distance data and the first position information are known, a distance measurement instruction may be sent to the two second anti-lost device control terminals, and then, combined with the second The second distance data and the second position information, or the third distance data and the third position information, determine the circle with the first position as the center and the first distance as the radius as the first position range, and use two second anti-lost devices The circle returned by the control end centered on the second position and the second distance radius is determined as two second position ranges, and the circle centered on the third position and the third distance radius is determined as two third position ranges. The overlap between the first position range, the two second position ranges, and the two third position ranges, or the intersection of the above circles, is the position or position range of the first anti-lost device terminal. For more control terminals of the second anti-lost device, the positioning of the first anti-lost device terminal may be implemented in the same manner as described above, and details are not described herein again.

The above second anti-lost device control terminal may be determined according to which anti-lost device control terminals actually exist around the first anti-lost device control terminal, or may be determined by the server according to requirements and/or known data. For example, in a case where the first anti-lost device terminal needs to be accurately positioned, three or more second anti-lost device control terminals may be determined. Without knowing the precise positioning of the first anti-lost device terminal, for example, if only the location range of the first anti-lost device terminal needs to be known, one or two second anti-lost device control terminals can be determined. There are no restrictions.

Therefore, based on the above technical solution, regardless of whether the distance between the first anti-lost device control terminal and the first anti-lost device terminal is known, other anti-lost device control terminals (ie, the second anti-lost device control terminal) can be passed The second position information and the second distance data and the third position information and the third distance data provided by the multi-point positioning method are used to locate the first anti-lost device terminal. This solution can greatly increase the monitoring distance of the anti-lost device control terminal to the anti-lost device terminal, so that it is not limited to the short-distance working distance based on Bluetooth communication technology, and at the same time can achieve accurate positioning of the anti-lost device terminal In order to facilitate the manager of the control side of the anti-lost device to navigate or track the person or item that needs anti-lost management, improve search efficiency.

Anti-lost alarm

Further, the first distance between the first anti-lost device control terminal and the first anti-lost device terminal is determined according to the first position information of the first anti-lost device control terminal and the determined position of the first anti-lost device terminal. Or according to the first distance between the first anti-lost device terminal and the first anti-lost device terminal measured by the first anti-lost device terminal, anti-lost device monitoring of the first anti-lost device terminal can be implemented.

As an example of the present disclosure, multiple alarm levels may be set for the first anti-lost device terminal, and the multiple alarm levels may respectively correspond to multiple distance ranges. Accordingly, the alarm level for the first anti-lost device terminal may be determined based on the distance range to which the distance between the first anti-lost device terminal and the first anti-lost device terminal belongs. Among them, different alarm levels may be set for different first anti-lost device terminals, and different alarm levels may include different numbers of alarm levels, different multiple distance ranges, or different warning information.

Specifically, for the first anti-lost device terminal, based on the distance between the first anti-lost device terminal and the corresponding first anti-lost device control terminal, a plurality of warning circles (corresponding to the first anti-lost device control Circle with multiple distances between the ends), the distance range between two adjacent alarm circles is regarded as the distance range corresponding to the relevant alarm level.

For example, the circles separated by a first (two/three/fourth...) distance between the first anti-lost device terminal and the corresponding first anti-lost device control terminal respectively correspond to the alarm circle 1 (2/3/4... …), then the range between the alarm circle 1 and the alarm circle 2 corresponds to the first distance range and the first alarm level, and when the anti-lost device terminal is in the first distance range, a response is sent to the first anti-lost device control terminal Warning for the first alarm level; the range between the alarm circle 2 and the alarm circle 3 corresponds to the second distance range and the second alarm level, when the anti-lost device terminal is in the second distance range, the first anti-lost device The control terminal issues a warning for the second alarm level; the range between the alarm circle 3 and the alarm circle 4 corresponds to the third distance range and the third alarm level. When the anti-lost device terminal is in the third distance range, the An anti-lost device control end issues a warning for the third alarm level...

Therefore, the real-time positioning of the first anti-lost device terminal can be used to control the first anti-lost device when the distance between the first anti-lost device terminal and the first anti-lost device control terminal is within a corresponding distance range. The manager at the terminal issues a warning corresponding to the distance range to remind the manager to manage and track the first anti-lost device terminal to avoid the loss of the first anti-lost device terminal.

Wireless ranging

As described above, the first or second anti-lost device control terminal and the second anti-lost device terminal can communicate with the first anti-lost device terminal through wireless communication to measure the distance between the two. The control terminal of the second anti-lost device can also be connected to the first anti-lost device terminal nearby by wireless communication. Among them, the range of "nearby" has different meanings in different scenes. For example, it may be determined by the wireless communication capability between the second anti-lost device control terminal or the second anti-lost device terminal and the first anti-lost device terminal.

The control terminal side of the first and/or second anti-lost device may include a signal (for example, ranging message) sending terminal, and the first anti-lost device terminal side may include a signal feedback terminal (that is, a feedback message sending terminal), the signal is sent The terminal and the signal feedback terminal can be, for example, low-power, high-performance zigbee modules, by measuring the transmission time of the message between the signal sending terminal and the signal feedback terminal (for example, the anti-lost device control terminal sends a ranging message and receives a feedback message Time difference) to determine the distance between the two.

The second anti-lost device terminal itself may also include a sending end of the above signal (for example, a ranging message). The second anti-lost device terminal may measure the third distance data between it and the first anti-lost device terminal in response to an instruction from the second anti-lost device control terminal. The signal sending end of the second anti-lost device terminal side can also be a low-power, high-performance zigbee module, which measures the transmission time of the message between the signal sending end and the signal feedback terminal (for example, the second anti-lost device terminal side sends a measurement Time difference between the message and the received feedback message) to determine the distance between the two.

Specifically, the first or second anti-lost device control terminal or the second anti-lost device terminal may send a ranging message to the first anti-lost device terminal and receive a response from the first anti-lost device terminal in response to the ranging message The feedback message determines the distance between the second anti-lost device control terminal or the second anti-lost device terminal and the first anti-lost device terminal based on the feedback message.

In one embodiment, the control terminal of the second anti-lost device may send the determined distance data to the server side. In another embodiment, the second anti-lost device control terminal may use relevant data (such as measured data) for determining the distance between the second anti-lost device control terminal or the second anti-lost device terminal and the first anti-lost device terminal. Time data such as the message sending time, feedback message receiving time, etc.) is sent to the server side, so that the server side can determine the second anti-lost device control terminal and the second anti-lost device terminal and the first anti-lost device terminal according to the relevant data the distance between.

It should be understood that the anti-lost device control terminal of the present disclosure may also measure the distance between it and the anti-lost device terminal by other technical means, and the present disclosure does not limit this. In addition, the descriptions of "first", "second", and "third" in the text are intended to distinguish the description objects, rather than have any explicit or implicit provisions on the order or function.

As another example of the present disclosure, in response to the first anti-lost device terminal positioning request, one or more available second anti-lost devices within a first predetermined distance range of the control terminal of the first anti-lost device may also be determined器控制端。 The control terminal. Among them, "available" can be understood as that the control terminal of the anti-lost device can measure the distance between it and the first anti-lost device terminal.

Among them, the first predetermined distance range may be set independently by the user, or may be adaptively set according to the ranging capability between the anti-lost device control terminal and the anti-lost device terminal, and may be several hundred meters or more The distance value. For example, the first predetermined distance range may be the maximum ranging distance between the first anti-lost device control terminal and the anti-lost device terminal, or the first predetermined distance range may also be the first anti-lost device control terminal and the anti-lost device The Bluetooth connection distance between the terminals, or the first predetermined distance range may be dynamically set by the administrator.

Therefore, in combination with the distance data and/or position data provided by a plurality of other anti-lost device control terminals that are close to the first anti-lost device control terminal, the first anti-lost device terminal can be accurately determined by a multi-point positioning method Not only can increase the working distance of the control terminal of the first anti-lost device, but also can provide relevant managers with real-time positioning and navigation tracking services of the first anti-lost device terminal.

Considering that the anti-lost device control terminal and the anti-lost device terminal may move with the person or item they are bound to, then there may also be a second anti-lost device control terminal that moves out of the first predetermined distance range of the first anti-lost device control terminal There may be a situation where another new second anti-lost device control terminal enters the first predetermined distance range of the first anti-lost device control terminal due to movement.
