The playing host and the audio box device support wireless communication protocols, and can perform wireless communication with each other, which is as follows:
1) the wireless communication protocol of all members in the system is opened, and the player host searches and connects other members in the equipment group, namely the sound box 1 and the sound box 2.
2) Judging the position of the sound box 1 and the sound box 2 relative to the host, the playing host respectively sending control signals to the sound box 1 and the sound box 2 through a wireless communication protocol, the sound box 1 and the sound box 2 respectively playing a section of audio file and being received by the playing host, the microphone array on the playing host judging the position of the sound box 1 and the sound box 2 relative to the own through a sound source positioning algorithm, as shown in figure 5, when the sound box 1 and the sound box 2 respectively produce sound, the four microphones of the microphone array on the player main machine receive the sound at different time, the time difference between the sound signal from the loudspeaker and the 4 microphones of the host system can be calculated by the system, at a sampling frequency of 16K, the distance from the leftmost microphone to the rightmost microphone is required to be not less than 5cm, and at a sampling frequency of 48K, the distance is required to be not less than 2 cm. If a directional microphone with direction sensing is adopted, the specific direction angle of the sound box can be obtained. This is more advantageous for calculating the situation of multiple speakers. Recording t (1, 1) as the moment when the microphone 1 receives the sound box 1, and t (4, 1) as the moment when the microphone 4 receives the sound box 1, we define that if t (1, 1) > t (4, 1) the position is the left side of the main machine, otherwise, the position is the right side of the main machine, so that the signal of the left channel can be sent to the sound box 2, and the signal of the right channel can be sent to the sound box 1.
3) After the relative positions of the sound box 1 and the sound box 2 and the host are judged, the play host carries out the following processing: the audio signal of the left channel is transmitted to the sound box 2, the audio signal of the right channel is transmitted to the sound box 1, and at this time, the sound box 1 and the sound box 2 can respectively receive and output respective audio signals through own wireless communication protocols.
According to the embodiment, the relative position of each sound box is automatically judged by the playing host machine as long as the sound box is placed, and the audio signal of the corresponding sound channel is sent to each sound box, so that the self-adaptive transmission of the sound signal is realized, and a lot of unnecessary plug wire troubles are reduced.

As shown in fig. 5, the system is a 5.1 channel system, and the position of 6 sound boxes relative to the host can also be determined by the above method for determining positions, so that the host will transmit audio signals of different channels to corresponding sound boxes, and each sound box receives and outputs its own audio signal.
Example two
In the embodiment, the self-adaptive transmission of the control signal is mainly realized. The host is a control host, and the terminal is a signal lamp.
There are many applications of control signals, such as switching of traffic lights, switching states of certain devices, etc.
Fig. 6 is a schematic diagram of a signal lamp system in an embodiment of the invention. As shown in fig. 6, the signal lamp system includes a control host and at least two signal lamps, each of which can display red or green status, and the control host and the signal lamps are equipped with positioning devices. In fig. 6, the signal lamps 1 and 2 are grouped into one group, and the signal lamps 3 and 4 are grouped into one group, however, the grouping situation of the signal lamps can be changed according to the own needs, which is only one possible situation in this embodiment. The control host locates the relative positions of the 4 signal lights with respect to itself by a predetermined calculation method of position information. When the control host finds that the signal lamp 1 is beside the control host, the signal lamp 2 is at the far end (opposite end) of the control host, the numbers 1 and 2 can be uniformly grouped, and the signal lamps 3 and 4 are respectively at the left side and the right side of the control host, so that the numbers 3 and 4 are grouped into a group. After the position judgment is completed, the control host can respectively transmit the control signals to be displayed to two groups according to a grouping mode, and the switching of the control signals and the communication channels can be completed through an automatic control relay in the control host.
Fig. 7 is a schematic view of the embodiment of fig. 6 after the position of the signal lamps 2, 3 has been interchanged. As shown in fig. 7, the control host will reposition the relative positions of the signal lights, and after the relative positions of the signal lights are located, the control host will send corresponding control signals to 4 signal lights, at this time, the signal light 2 and the signal light 4 will be a group sharing the same communication channel, and the signal light 3 and the signal light 1 will be a group sharing another communication channel. This enables a self-adaptation of the control signal.
Examples of the above application scenarios: say that entrance and exit of cinema say, the place that green light is bright represents entrance, and the place that red light is bright represents exit, just so can realize through the method of this embodiment, and control mode can be that the left signal lamp red light of control host computer is bright, and the green light of right signal lamp is bright, and the mode of putting can be as shown in fig. 8, and fig. 8 is the schematic diagram of cinema's signal lamp system in the embodiment of the utility model. Therefore, when the positions of the exit and the entrance are required to be changed, the control signals can be switched only by judging the respective positions again by the control host.
EXAMPLE III

As shown in fig. 9, the split screen television includes a broadcast host and 9 screens, the broadcast host and 9 screens both support wireless communication protocols, and the broadcast host and each screen are equipped with a positioning device, the broadcast host can determine the relative positions of the 9 screens by a predetermined position information calculation method, and then output the signals of different screens to the corresponding screens by the wireless communication protocols, i.e. the screen 1 corresponding to the screen 1 transmits signals, the screen 2 corresponding to the screen 2 transmits signals, the screen 3 corresponding to the screen 3 transmits signals, and so on, each screen can receive respective signals by its own wireless receiving device and display and output the signals.
Therefore, different video signals can be output to the corresponding screens only by judging the relative position of each screen relative to the playing host, and the playing host does not need to correspond to each screen through a plug wire every time.
In summary, in the system of the present invention, in which the host and the plurality of terminals communicate with each other wirelessly, the host obtains the position information of the host and the position information of each terminal, then calculating the relative position relationship between the host and each terminal according to the acquired position information, matching each communication signal to be transmitted with each terminal according to the relative position relationship between the host and each terminal, and wirelessly transmitting corresponding communication signals to each terminal according to the matched corresponding relationship, because the host and each terminal adopt a wireless transmission mode, the complex wiring and plug wire processes are avoided, and the host computer obtains the relative position relationship between itself and each terminal, matches the communication signal and the terminal according to the relative position relationship, then, wireless transmission of the communication signal is performed, so that self-adaptive transmission of the wireless signal can be realized.
