It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. In the drawings, elements having similar structures are denoted by the same reference numerals. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "first", "second" and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

The embodiment of the application provides a scanning method, a scanning device, a storage medium and a scanning system.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a scanning system provided in an embodiment of the present application, where the scanning system is composed of a plurality of cascaded network groups, each network group includes a master device and at least one slave device, and the master device in the current-level network group is a slave device in a previous-level network group, as shown in fig. 1, the scanning system includes three cascaded network groups (a master group, a relay group, and a scanning group), where the master group and the relay group are cascaded through a relay device 1, and the relay group and the scanning group are cascaded through a relay device 2, and they jointly form a neighbor awareness network cluster. The relay device 1 is a master device in the relay group and a slave device in the master group, and the relay device 2 is a slave device in the relay group and a master device in the scanning group.

Specifically, after receiving a call for help from a help-seeking person, the master device in the master group first obtains location information of a top antenna of a base station communicating with a terminal of the help-seeking person, then controls a slave device (indicated by x in the figure) in the scanning group to be in position around the top antenna of the base station according to a preset distribution rule, then sends a scanning instruction to the slave device in the scanning group so that the slave device scans the terminal signal strength of the help-seeking person according to the scanning instruction, after the slave device in the scanning group scans the terminal signal strength of the help-seeking person, feeds the terminal signal strength value back to the master device in the master group, the master device in the master group further reduces the scanning range according to the fed-back terminal signal strength value, and then instructs the slave device in the scanning group to redistribute and scan until the signal strength value is large enough or the scanning range is small enough, when the device can be used for search and rescue personnel to refer, the scanning is stopped.

It should be noted that one device in each network group may communicate with not only another device in the same network group device, but also multiple, or even all devices in the same network, where the relay device may communicate with devices in two cascaded networks, for example, the manner of scanning the slave device in the group to feed back the signal strength value to the master device in the master group is as follows: the slave devices in the scanning group send signal strength values to the relay device 2, then the relay device 2 sends the signal strength values to the relay device 1, and then the relay device 1 sends the signal strength values to the master device in the master device.

Specifically, the communication range of each network group is 200 meters, and therefore, in order to keep the scanning group and the relay group in communication, the relay device 2 does not perform scanning and redistribution, so as to prevent the relay device 2 from departing from the communication range of the relay group, which results in the scanning group being unable to communicate with the master group. It is easy to understand that, since the communication range of each network group is 200 meters, if the distance between the master group and the scanning group is relatively long, a plurality of cascaded relay groups can be arranged between the master group and the scanning group.

Referring to fig. 2, fig. 2 is a schematic flowchart of a scanning method provided in an embodiment of the present application, where the scanning method is applied to a master device of a master group in a neighbor-aware network cluster, where the neighbor-aware network cluster includes a plurality of cascaded network groups, each network group includes one master device and at least one slave device, the master device in the current-level network group is a slave device in a previous-level network group, the neighbor-aware network cluster includes one master group and one scanning group, and a specific flow of the scanning method mainly includes steps S101 to S105, which are described as follows:

s101: and sending a scanning instruction to the slave equipment in the scanning group, wherein the scanning instruction carries a terminal identifier and is used for indicating the slave equipment in the scanning group to scan the signal intensity value of the terminal corresponding to the terminal identifier at the scanning position of the slave equipment according to the terminal identifier.

In this embodiment, before step S101, the method may further include: acquiring position information of a top antenna of a base station; and determining the initial scanning position of each slave device in the scanning group according to the preset distribution rule and the position information, and sending the initial scanning position to the corresponding slave device.

Specifically, when the help seeker calls for help, the main control equipment automatically acquires base station information communicated with the help seeker, further, the area, near the base station, of the help seeker can be preliminarily determined, the base station information comprises position information of a top antenna of the base station, and the position information can comprise longitude and latitude and height information

For example, in this embodiment, the preset distribution rule may be a three-dimensional lower hemisphere centered on the antenna at the top of the base station, and a radius of the three-dimensional lower hemisphere may be 200 meters. Further, the preset distribution rule may also specify the density of the slave devices and/or the distance between the slave devices in the distribution shape, for example, the slave devices in the scanning group may be uniformly distributed in the distribution shape.

Therefore, the starting scanning position of each slave device can be obtained according to the preset distribution rule and the position information of the top antenna of the base station, and the starting scanning position can comprise longitude and latitude information and height information.

By sending the start scanning position to the corresponding slave devices, the slave devices can be distributed according to the start scanning position, and signal scanning is performed in subsequent steps. For example, the slave devices in the scanning group may be unmanned aerial vehicles, such as drones, which are distributed according to the longitude and latitude information and the altitude information in the initial scanning position after each drone receives the initial scanning position.

In this embodiment, after the slave devices in the scanning group are distributed according to the initial scanning position, the information is fed back to the master device in the master group, and when the master device in the master group receives the feedback message, the scanning instruction is sent to the slave device in the scanning group.

It should be noted that all devices in the neighbor aware network cluster communicate by using a service discovery Frame to carry messages, and a format of the service discovery Frame is shown in table 1, where Category refers to that a type of the Frame is a Public Action Frame (Public Action Frame), Action Field refers to a Public Action Frame related to a specified manufacturer, OUI refers to an organization Unique number (organization Unique Identifier); OUI Type refers to the Type of OUI, and Attributes refers to Attributes. Further, the Attributes includes a service description Attribute and a manufacturer specific Attribute, in the manufacturer specific Attribute, Attribute ID refers to the number of the manufacturer specific Attribute, Length refers to the sum of the byte lengths of OUI and Body, OUI refers to the number of the manufacturer, and Body refers to specific information of the manufacturer.

TABLE 1

In this embodiment, table 1 may be simplified to the form shown in table 2 below, where the Body field in table 2 is the Body field in table 1, and the definition and description of the message ID in table 2 are shown in table 3.

TABLE 2

Message ID	Description of the invention
		0x01	Scanning position
0x02	Scan instruction
		0x03	Signal strength value of terminal

TABLE 3

It is easily understood that the format of the information for the master device in the master group to send the initial scanning location to the slave devices in the scanning group is shown in table 4, and the slave devices in the scanning group recognize the message as the scanning location information by the message ID (0x 01).

TABLE 4

In addition, the information format that the master device in the master group sends the scan instruction to the slave devices in the scan group is shown in table 5, and the slave devices in the scan group identify the message as the scan instruction by the message ID (0x02), where the scan instruction carries the terminal identifier.

TABLE 5

S102: and when receiving the signal strength value forwarded by the slave equipment in the scanning group, determining the next scanning center according to the signal strength value.

In this embodiment, step S102 may include: and determining the current position of the slave device with the maximum forwarded signal strength value as the next scanning center.

For example, as shown in fig. 3, at the beginning, the slave devices in the scanning group are arranged in a three-dimensional lower hemisphere shape with the top antenna of the base station as the center, where the signal strength value forwarded by the device a is the largest, and then the next scanning center is determined as the current position of the device a.

S103: and determining the next scanning range according to the next scanning center.

In this embodiment, step S103 may mainly include the following sub-steps:

acquiring the coverage area of the current scanning range;

the target coverage area centered on the next scanning center is taken as the next scanning range.

Specifically, the coverage area may be a circle, and the coverage area is reduced according to a preset ratio, which may be considered to reduce the radius of the coverage area of the current scanning range according to the preset ratio. For example, as shown in fig. 3, at the beginning, the slave devices in the scanning group are distributed in a three-dimensional lower hemisphere shape with a radius of 200 meters and a top antenna of the base station as a center, and after determining that the next scanning center is the current position of the device a, the coverage area of the current scanning range is reduced according to the preset scale, that is, the radius is reduced to 100 meters, and the next scanning range is in a three-dimensional lower hemisphere shape with the device a as the center and the radius of 100 meters.

S104: the next scanning position of each slave device in the scanning group in the next scanning range is determined, and the next scanning position is sent to the corresponding slave device, so that each slave device is located at the scanning position of the slave device in the next scanning range.

The message format for the master device in the master group to send the next scanning position to the slave devices in the scanning group is shown in table 3.

Specifically, the next scanning range is obtained by further reducing the coverage area with the current position of the slave device with the maximum forwarded signal intensity value as the center, and it can be considered that the position with the maximum signal intensity value is the closest to the terminal of the help seeker in the current scanning range, and therefore, the next scanning range can be considered as a range closer to the terminal of the help seeker. After the next scan range is determined, the next scan position of each slave device is determined, and the next scan position is sent to the corresponding slave device, so that the slave devices can be distributed in position according to the next scan range for further scanning in the subsequent steps or for reference of search and rescue personnel.

In some embodiments, the next scanning position of each slave device in the scanning group may be determined according to the preset distribution rule and the next scanning range.

S105: and if the signal intensity value and the next scanning range do not meet the preset conditions, returning to the step of executing the step S101 until the signal intensity value or the next scanning range meets the preset conditions.

In this embodiment, step S105 may be preceded by: and if the target coverage area is not larger than the preset coverage area, judging that the next scanning range meets the preset condition.

Specifically, the preset coverage area may be an area of a circle with a radius of one meter, and when the target coverage area is smaller than or equal to the area of the circle with the radius of one meter, it may be considered that the distribution of the slave devices in the scanning group is sufficiently tight, so that the search and rescue personnel can perform search and rescue as an aerial reference object. It should be noted that the preset coverage area may be set manually, and the embodiment of the present application does not limit this.

In this embodiment, before step S105, the method further includes: and if the number of the signal strength values which are greater than the preset signal strength value in all the signal strength values is not less than the preset number, judging that the signal strength values meet the preset condition.

Specifically, the preset signal strength value may be a signal strength value used for indicating that the distance between the slave device and the help seeker terminal is close enough, and the preset number may be set according to the total number of the slave devices in the scanning group, which is not limited in this embodiment of the present application. If the number of the signal strength values which are greater than the preset signal strength value in all the signal strength values is not less than the preset number, the distance between the slave device and the help seeker terminal can be considered to be close enough, and the help seeker can search and rescue as an aerial reference object.

Specifically, each slave device in the scanning group may be provided with an infrared sensor, and the distance to the obstacle is determined by the distance measurement of the infrared sensor, so as to avoid touching the obstacle during the movement.

It can be known from the foregoing that, this embodiment provides a scanning method, where the scanning method is applied to a master device of a master group in a neighbor-aware network cluster, where the neighbor-aware network cluster includes a plurality of cascaded network groups, and the plurality of cascaded network groups include a master group and a scanning group, where each network group includes a master device and at least one slave device, and the master device in the current-level network group is a slave device in a previous-level network group, the scanning method includes: and sending a scanning instruction to the slave equipment in the scanning group, wherein the scanning instruction carries a terminal identifier and is used for indicating the slave equipment in the scanning group to scan the signal intensity value of the terminal corresponding to the terminal identifier at the scanning position of the slave equipment according to the terminal identifier, and when the signal intensity value forwarded by the slave equipment in the scanning group is received, determining the next scanning center according to the signal intensity value. And then determining a next scanning range according to the next scanning center, then determining the next scanning position of each slave device in the scanning group in the next scanning range, and sending the next scanning position to the corresponding slave device, so that each slave device is located at the scanning position in the next scanning range, if the signal intensity value and the next scanning range do not meet the preset conditions, returning to the step of sending a scanning instruction to the slave devices in the scanning group, and stopping until the signal intensity value or the next scanning range meet the preset conditions, so that the search and rescue personnel can take the positions of the slave devices in the scanning group as aerial reference objects, search and rescue personnel according to the images, and improve the search and rescue efficiency and the search and rescue effect.
