Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application provides a positioning system of a target object, which can be used for accurately finding the target object.
Fig. 1 is a schematic view schematically illustrating an object positioning system according to an embodiment of the present application. The system 100 includes a tracking device 101 for use by an object finder, and at least one positioning device, such as positioning device 1021, positioning device 1022, and positioning device 1023 shown in fig. 1, which can be disposed on an object, such as positioning device 1021 shown in fig. 1, disposed on object a, positioning device 1022 disposed on object B, and positioning device 1023 disposed on object C.
In the embodiment of the present application, the target object may be a living object, such as a person or a pet, and accordingly, the system may be used for finding a pet or finding a child. Taking the pet finding as an example, the target object may be a pet out of sight, the positioning device may be worn on the pet, the finder may be the owner, and the owner holds the tracking device 101.
The target object may also be an inanimate object, such as a product in industrial production or a daily article (e.g., a key, a wallet), etc. Taking industrial production as an example, the target object may be a sample or a product, the positioning device is disposed on the sample or the product, and the object finder may be a worker, and the worker holds the tracking device 101.
It should be noted that the object positioning system provided in the embodiment of the present application may be applied to various scenarios, and fig. 1 illustrates a typical application of the object positioning system, which does not constitute a limitation on the application of the object positioning system.
The tracking device 101 may be various types of terminal devices, such as a smart phone, a tablet computer, a smart wearable device, and the like, and is not limited in particular.
Further, the positioning device may carry identification information of the target object, for example, the positioning device 1021 carries identification information of the target object a, the positioning device 1022 carries identification information of the target object B, and the positioning device 1023 carries identification information of the target object C. That is, one tracking device may be matched with a plurality of positioning devices, so that when the person needs to search for the object a, the tracking device 101 may send an object positioning request to the positioning device 1021.
Based on the system shown in fig. 1, fig. 2 exemplarily shows a flow diagram corresponding to a target object positioning method provided in the embodiment of the present application, and specifically includes the following steps:
in step 201, the tracking device obtains a first fuzzy range of the target object based on the GPS technology.
If the target object is not found within the first ambiguity range, the tracking device sends a first target object location request to the target location device based on UWB technology, step 202.
In step 203, the tracking device receives a first response message returned by the target positioning device.
Step 204, the tracking device generates a first indication message according to the first target distance.
In the embodiment of the application, the fuzzy range of the target object is acquired in a larger range by using the GPS technology, if the target object is not acquired in the fuzzy range, the distance between the target object and an object finder is acquired by using the UWB technology again, and the target object is accurately positioned by using the UWB technology. The GPS technology and the UWB technology are combined, the GPS technology realizes low-cost fuzzy range positioning of the target object, and the UWB technology realizes accurate positioning of the target object, so that the positioning and calculating accuracy of the target object can be improved, and a person seeking the target object can be helped to quickly find the target object.
The procedure of the target object locating method will be described in detail below.
In step 201, the value of the first fuzzy range may be several meters to several tens of meters, and this value may vary according to the accuracy of different GPS locators, which is not specifically limited in this application.
Within the first fuzzy range, if the target object is found directly, the positioning process for the target object is ended. Only in case no target object is found, the step 202 needs to be continued.
In step 202, the tracking device sends the first object location request in various ways, for example, the tracking device can be controlled by an object finder and sends the first object location request when the object finder needs to obtain the position of the object.
For another example, a period may also be preset, and when the person needs to find the object, the tracking device may periodically send a first object location request. In the embodiment of the application, the target positioning device is a positioning device worn on a target object.
For example, taking the system shown in fig. 1 as an example, when the person seeking the object needs to search for the object a, the positioning device 1021 carried by the object a is used as the object positioning device.
In the embodiment of the present application, the tracking device may be regarded as a base station in UWB technology, and the positioning device may be regarded as a terminal device communicating with the base station.
The tracking device may generate a first target object location request according to the identification information of the target object, where the first target object location request includes the identification information of the target object.
Furthermore, when the tracking device sends the first target object location request, the tracking device may send the first target object location request to a location device (i.e., a target location device) corresponding to the identification information of the target object; or, the tracking device may broadcast the first target object locating request, and after receiving the first target object locating request, the locating device may determine whether the identification information of the target object included therein is consistent with the identification information of the target object wearing the locating device, and if so, the tracking device is the target locating device, and if not, the tracking device is not the target locating device.
In step 203, the first response message is sent by the target positioning device after receiving the first target object positioning request.
The first response message may include a first target distance between the target locating device and the tracking device. The first target distance may be determined by:
determining the time at which the first response message is transmitted from the target location device to the tracking device based on the time at which the tracking device receives the first response message and the time at which the target location device replies to the first response message; further, based on the time of transmission of the first response message from the target locating device to the tracking device, and the speed of propagation of the first response message (e.g., speed of light), the distance between the target locating device and the tracking device (i.e., the first target distance) may be determined.
Further, the target object is movable, and the person who may find the target object is within the first fuzzy range, and the target object has moved away from the first fuzzy range. This results in the tracking device having exceeded the receiving range of the target locating device after issuing the target locating request, and therefore the tracking device will not receive the response message returned by the target locating device.
In order to solve the above problem, in the embodiment of the present application, if the first response message returned by the target location device is not received within the preset time period, the tracking device may acquire the second fuzzy range of the target object based on the GPS technology. After the second ambiguity range is obtained, the UWB technology can be used to perform accurate positioning (i.e., return to step 202) until the target object is found.
The time length of the preset time period may be determined by a person skilled in the art based on experience or actual conditions, and is not limited specifically.
It should be noted that, in the process of finding the target object, the fuzzy range of the target object may be obtained based on the GPS technology for multiple times, and in the embodiment of the present application, for convenience of describing a single process, a distinction is made between "first" and "second".
In this embodiment of the application, after the tracking device receives the first response message returned by the target positioning device, monitoring of the target object may be further achieved according to the first target distance.
Specifically, whether the first target distance is larger than a preset target object moving range or not is judged, if the first target distance is larger than the preset target object moving range, the tracking device sends an alarm instruction, and the alarm instruction is used for reminding the object finder that the target object exceeds the preset target object moving range.
For example, in an industrial process, a worker may temporarily take a sample off the production line and perform some experiments. During the experiment, the sample may be moved out of the factory while being mixed in a general product due to the error of a worker. In this case, the embodiment of the application may preset a movable range of the target object, and when the target distance received by the tracking device is greater than the preset movable range of the target object, it indicates that the movable range of the target object is not within the control range of the staff, and at this time, the tracking device sends an alarm instruction, where the alarm instruction is used to remind the staff that the target object is beyond the preset movable range of the target object.
For another example, the owner goes out and places the pet alone at home. At this time, the owner wants the pet to have a certain activity space, but does not want the pet to be lost. The moving range of a pet can be preset, when the target distance received by the tracking device is larger than the preset moving range of the pet, the moving space of the pet is not in the control range of the owner, the tracking device sends out an alarm instruction at the moment, and the alarm instruction is used for reminding the owner that the pet exceeds the preset moving range of the pet.
In step 204, the first indication message may be used to instruct the finder to find the target object according to the first target distance.
For example, assuming that the first target distance is 5 meters, the finder can determine that the target is within 5 meters of the finder, and then the finder can find the target within 5 meters.
Considering that the direction of the target object is uncertain, the person who looks for the target object may move about freely to look for the target object, and therefore, the person who looks for the target object may not find the target object in the actual process of looking for the target object. At this time, reference may be made to fig. 3, which schematically shows a flow chart corresponding to another target object positioning method provided in the embodiment of the present application, where the flow chart may be executed after the step 204, and specifically includes the following steps:
if the object finder does not find the object according to the first indication message, the tracking device sends a second object location request to the object location device based on UWB technology again, step 301.
Step 302, the tracking device receives a second response message returned by the target positioning device.
Wherein the second response message is sent by the target positioning device after receiving the second target object positioning request.
The second response message may include a second target distance between the target locating device and the tracking device. The determination manner of the second target distance is similar to that of the first target distance, and is not described herein again.
Step 303, determining whether the second target distance is smaller than the first target distance, if so, executing step 304; otherwise, step 305 is performed.
At step 304, the tracking device generates a second indication message.
Wherein the second indication message can be used for indicating the finder to keep the current direction to continue to find the target object.
If the second target distance is smaller than the first target distance, the moving direction of the object-seeking person is a direction close to the target object, and therefore the second indication message generated by the tracking device indicates that the object-seeking person keeps the current direction to continue seeking the target object.
At step 305, the tracking device generates a third indication message.
And the third indication message is used for indicating the finder to continue to find the target object after adjusting the direction.
If the second target distance is greater than or equal to the first target distance, which indicates that the moving direction of the object finder is away from the target object, the third indication message generated by the tracking device indicates that the object finder continues to find the target object after adjusting the direction.
It should be noted that, in the process of finding the target object by the finder, the process described in the above steps 301 to 305 may be repeated for a plurality of times, so as to facilitate the finder to find the target object more quickly.
The object may not be found after the person who seeks the object adjusts the direction for many times by considering that the object may change the position.
Based on this, in the embodiment of the application, if the target object is not found, the tracking device may send a ring instruction to the target locating device, where the ring instruction is used to instruct the target locating device to ring, so that the object finder searches for the target object according to the ring.
