and S1, detecting the display equipment corresponding to the control equipment.
In the embodiment of the present invention, the control device may detect the display device corresponding to the control device in real time, and may also detect the display device corresponding to the control device at every first interval in order to save power consumption. The control device may also start to detect its own corresponding display device according to the received control instruction, for example, recognize the received voice information to obtain the control instruction, and start to detect its own corresponding display device according to the control instruction (real-time detection or first duration detection at each interval).
Specifically, step S1 includes:
and S11, acquiring first position information of the control equipment, and monitoring a plurality of heartbeat packets.
In an example of this embodiment, the first location information is location information of the control device itself, which is used to reflect the location of the control device, and the location information may be represented by coordinates. The control device may be an intelligent device equipped with a driving device, such as a mobile Robot, which may map the environment in advance, for example, using a Robot Operating System (ROS) to perform laser synchronized positioning and mapping (SLAM). After the global mapping is carried out, the mobile robot moves to a certain position, and first position information corresponding to the position can be determined.
In one example of this embodiment, the control device may be an intelligent device, such as an intelligent remote control, which is not equipped with a driving apparatus. The control device determines first location information of itself through a positioning technology, for example, positioning is performed through GPRS, so as to obtain the first location information of itself.
In the embodiment of the invention, when the control device is a movable robot, the control device can also be positioned through GPRS (general packet radio service), when the control device is an intelligent device which is not provided with a driving device, the environment where the control device is located can also be globally mapped in advance, and when the intelligent device moves to a certain position, the first position information corresponding to the position can be determined.
In the embodiment of the present invention, the heartbeat packet is transmitted every fixed time interval, for example, every 1 second interval. The heartbeat packet is a data packet sent by a display device in communication connection with the control device, and the heartbeat packet is used for reflecting the running state of the display device sending the heartbeat packet; the operation state of the display device includes: the playback status of the display device, the position information of the display device, etc. After the display equipment is started, if the communication connection with the control equipment is successfully established, a heartbeat packet is sent to the control equipment so as to keep long connection with the control equipment. When a plurality of display devices are in communication connection with the control device, the control device can receive a plurality of heartbeat packages. The monitoring of the plurality of heartbeat packets means that the control device receives heartbeat packets respectively sent by the plurality of display devices.
And S12, determining the display equipment corresponding to the control equipment according to the first position information and the heartbeat packets.
In this embodiment of the present invention, for each heartbeat packet in the plurality of heartbeat packets, the heartbeat packet at least includes: sending position information and equipment information corresponding to the display equipment of the heartbeat packet, wherein the position information refers to the position of the display equipment, and the position information can be represented by coordinates; the device information includes a physical address of the display device, and when the display device that sends the heartbeat packet is in a playing state, the heartbeat packet further includes playing information corresponding to the display device, and the playing information includes a playing address, a playing duration and the like. For convenience of explanation, the position information included in the heartbeat packet is referred to as second position information. And determining the display equipment corresponding to the control equipment according to the second position information and the first position information (position information of the control equipment) corresponding to the plurality of heartbeat packages.
In one implementation, step S12 includes:

In the embodiment of the invention, after the display device is started, if the display device is successfully connected with the control device in a communication mode, a heartbeat packet is sent to the control device, and the communication connection mode can be wireless communication connection. When the display device connected with the control device in a communication mode is multiple, the control device can receive multiple heartbeat packages. The control device analyzes each received heartbeat packet to determine second position information corresponding to the heartbeat packet.
Since the heartbeat packet is sent by the display device, the essence of the second position information is the position information of the display device. The display device in the embodiment of the present invention may be a device which is not provided with a driving apparatus (which is not autonomously movable), such as a television; the display device not normally provided with the driving means does not frequently change its own position during use, and therefore, the position information (second position information) of the display device may be acquired in advance and added to the heartbeat packet. Alternatively, the display device in the embodiment of the present invention may be a device configured with a driving apparatus, and the display device acquires the position information (second position information) of the display device itself each time the display device transmits a heartbeat packet, and adds the position information of the display device itself to the heartbeat packet.
S122A, determining a target heartbeat package according to second position information corresponding to each of a plurality of heartbeat packages, wherein the distance between the first position information and the second position information corresponding to the target heartbeat package is the minimum.
In the embodiment of the invention, the control equipment calculates the distance between each second position information obtained by analysis and the first position information of the control equipment to obtain a plurality of distances; and determining a minimum distance in the plurality of distances, and taking the heartbeat packet corresponding to the minimum distance as a target heartbeat packet. The heartbeat packet corresponding to the minimum distance is as follows: and the heartbeat packet corresponding to the second position information corresponding to the minimum distance.
For convenience of description, the heartbeat packets except the target heartbeat packet in the plurality of heartbeat packets are recorded as non-target heartbeat packets, and a distance between the second position information corresponding to each non-target heartbeat packet and the first position information is greater than a distance (minimum distance) between the second position information corresponding to the target heartbeat packet and the second position information.
For example, the control device receives 4 heartbeat packets, which are p1, p2, p3 and p4 respectively, analyzes the second position information to obtain d1 corresponding to p1, analyzes the second position information to obtain d2 corresponding to p2, analyzes the second position information to obtain d3 corresponding to p3, and analyzes the second position information to obtain d4 corresponding to p 4; the position information of the control equipment is d0, the distance between d0 and d1 is calculated to be l1, the distance between d0 and d2 is calculated to be l2, the distance between d0 and d3 is calculated to be l3, and the distance between d0 and d4 is calculated to be l 4; assuming that l2 is minimum, the heartbeat packet p2 corresponding to d2 is taken as the target heartbeat packet.
And S123A, taking the display device corresponding to the target heartbeat packet as the display device corresponding to the control device.
In the embodiment of the present invention, the display device corresponding to the target heartbeat packet is the display device that sends the target heartbeat packet. For example, in the above example, if the heartbeat packet p2 corresponding to d2 is the target heartbeat packet, the display device that transmits the heartbeat packet p2 is the display device corresponding to the control device.
In another implementation, step S12 includes:
S121B, determining a target area set corresponding to the first position information according to a plurality of preset position area sets.
In the embodiment of the invention, the environment where the control equipment is located is divided into a plurality of position areas in advance, each position area corresponds to one position area set, and the position area set comprises a plurality of position area information. After the control equipment acquires the first position information of the control equipment, the first position information is matched with a plurality of preset position area sets so as to determine a target area set corresponding to the first position information.
For example, for several location area sets, if the first location information belongs to a first location area set of the several location area sets, the first location area set is taken as the target area set.
In this embodiment of the present invention, the plurality of location area information included in the location area set may be determined when performing SLAM mapping by using the ROS, an environment in which the control device is located is divided into a plurality of areas, each area corresponds to one location area set, and each location area set includes a plurality of location area information.
In the embodiment of the invention, the position areas can be divided according to the display devices, so that each position area is provided with one and only one display device. For example, in an environment with an area of 20m × 20m, a plurality of display devices may be included, and the 20m × 20m is divided into a plurality of location areas, and each location area includes one display device. In practical applications, the location area may be a real area in the environment, for example, in a home, a living room is used as one location area, and a bedroom is used as another location area.
And S122B, acquiring second position information corresponding to the plurality of heartbeat packages respectively.
In the embodiment of the present invention, the process of step S122B is the same as the process of step S121A, and further, for the process of step S122B, the description of step S121A may be referred to.
S123B, determining a target heartbeat packet according to second position information corresponding to each of the heartbeat packets, wherein the second position information corresponding to the target heartbeat packet belongs to the target area set.
In the embodiment of the invention, a target area set corresponding to a first position and second position information corresponding to each heartbeat packet are determined, and for each second position information, the second position information is matched with a plurality of preset position area sets to determine the position area set corresponding to the second position information; and taking the second position information belonging to the target area set as target information, and taking a heartbeat packet corresponding to the target information as a target heartbeat packet.
For example, the target area set corresponding to the first position is S0, the control device receives 4 heartbeat packets, which are p1, p2, p3 and p4, respectively, analyzes the received heartbeat packets to obtain second position information d1 corresponding to p1, analyzes the received heartbeat packets to obtain second position information d2 corresponding to p2, analyzes the received heartbeat packets to obtain second position information d3 corresponding to p3, and analyzes the received heartbeat packets to obtain second position information d4 corresponding to p 4; if the position region set to which d1 belongs is S1, the position region to which d2 belongs is S2, the position region to which d3 belongs is S0, and the position region to which d4 belongs is S3, the heartbeat packet p3 corresponding to d3 is taken as the target heartbeat packet.
And S124, 124B, using the display device corresponding to the target heartbeat packet as the display device corresponding to the control device.
