Description

Technical Field

[0001] The present invention relates to the field of directional sound generation, and in particular to a system and method for pushing signals based on location. Background Art

[0002] In international conferences, since people from different countries sit in different areas and due to the existence of simultaneous interpretation, the language heard in each area is different, and different voices need to be pushed to different areas.

[0003] At present, the main methods for pushing different sounds to different users include presetting target locations, pushing to different areas separately, and having different users wear independent headphones and other signal receiving devices, such as headphones / information receivers, etc. Among them, the preset target location often requires physically dividing independent spaces for different receivers to avoid mixing of sounds / information, which has high requirements for the venue, high costs, and inconvenient layout. Wearing headphones for different users also has problems such as high system complexity, high cost, and inconvenient movement. Summary of the invention

[0004] The purpose of the present invention is to provide a system and method for pushing signals based on location in view of the defects of the above-mentioned prior art, so that targets at different locations receive different signals and the system layout is simple.

[0005] In an embodiment of the present invention, a system based on location push signal is provided, which includes a signal push device with a positioning module and at least one signal receiving device with an electronic positioning tag. The positioning module is used to establish a spatial coordinate system with itself as the origin, and to locate the signal receiving device according to the electronic positioning tag. The signal push device also includes at least one directional sending module, which is used to send a set signal to the signal receiving device according to the orientation of the signal receiving device.

[0006] In an embodiment of the present invention, the positioning module is an ultra-wideband broadcast positioning module, a multi-antenna millimeter wave radar module, a three-dimensional ultrasonic positioning module or a three-dimensional electromagnetic coil positioning module.

[0007] In the embodiment of the present invention, the directional transmission module is an ultrasonic speaker.

[0008] In an embodiment of the present invention, when the signal pushing device includes multiple directional sending modules and the directional sending modules are ultrasonic speakers, if the signal receiving device needs to receive sound in a directionally manner, the multiple ultrasonic speakers simultaneously send ultrasonic waves to different positions near the signal receiving device according to the position of the signal receiving device to form stereo sound.

[0009] In the embodiment of the present invention, the directional transmission module is an information push device for directional transmission of carrier waves, and the signal receiving device includes a display screen for displaying information.

[0010] In an embodiment of the present invention, when there are multiple signal receiving devices, the signal pushing device groups the multiple signal receiving devices according to their positions, and uses different directional sending modules to send different signals to different grouping areas, so that signal receiving devices in different groups receive different signals.

[0011] In an embodiment of the present invention, when a group of users moves as a whole, the directional sending module responsible for the group automatically adjusts the signal sending direction; if an individual user in a group moves into the area of ​​another group, the user is automatically removed from the group and added to the group in the area where he is located; if the number of users in a group is reduced to 0, the directional sending module of the group is automatically allocated to other groups.

[0012] In an embodiment of the present invention, a signal push method based on the location push signal system is also provided, which includes:

[0013] The signal push device establishes a spatial coordinate system with itself as the origin, and locates the signal receiving device according to the electronic positioning tag of the signal receiving device;

[0014] Directional push of set signals towards the direction of the signal receiving device.

[0015] Compared with the prior art, the system and method based on location push signals of the present invention can automatically group users and adjust the signal sending direction according to the location detection tags worn by different users, thereby increasing user convenience. Users only need to carry location detection tags and do not need to wear headphones or other equipment. They can move freely in a designated space, which is easy to use and simple to operate, thereby reducing the rate of human damage to the equipment and reducing maintenance costs. The system is flexible in layout and only requires several devices to be arranged around the venue. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 As shown, in an embodiment of the present invention, a system based on location push signal is provided, which includes a signal push device 1 with a positioning module 11 and at least one signal receiving device 2 with an electronic positioning tag 21.

[0022] Together Figure 2 As shown, in the signal pushing device 1 , the positioning module 11 is used to establish a spatial coordinate system with itself as the origin, and to position the signal receiving device 2 according to the electronic positioning tag 21 of the signal receiving device 2 .

[0023] Together Figure 3 As shown, the signal push device 1 also includes at least one directional sending module 12, and the directional sending module 12 is used to send a set signal to the signal receiving device according to the position of the signal receiving device 2. When directional sounding is required, the signal push device 1 sends a directional signal to the position of the signal receiving device 2, thereby preventing other users from receiving the directional signal, which has high confidentiality and can also reduce the interference of this directional signal to other users.

[0024] In an embodiment of the present invention, the positioning module 11 is an ultra-wideband broadcast positioning module, a multi-antenna millimeter wave radar module, a three-dimensional ultrasonic positioning module or a three-dimensional electromagnetic coil positioning module, which can accurately locate the position of the electronic positioning tag. The electronic positioning tag 21 is an electronic tag corresponding to the positioning module. The directional sending module is a signal sending device that sends signals in a specific direction. For example, the directional sending module can be an ultrasonic speaker that can send ultrasonic waves in a specific direction; the directional sending module can also be an information push device for directional sending of carrier waves, and the carrier wave can be an ultrasonic wave for carrying information. The signal receiving device includes a display screen for displaying information. After receiving the information pushed by the information push device, the signal receiving device decodes the information and displays it on the display screen.

[0025] like Figure 4As shown, in one embodiment of the present invention, the signal pushing device 1 has a plurality of directional sending modules 12, and the directional sending modules 12 are ultrasonic speakers. If the signal receiving device needs to receive sound in a direction, the plurality of ultrasonic speakers simultaneously send ultrasonic waves to different positions near the signal receiving device according to the position of the signal receiving device to form stereo sound, and adjust the sound direction in real time according to the position of the signal receiving device to ensure that the user is always in the best sound field.

[0026] like Figure 5 As shown, in one embodiment of the present invention, there are multiple signal receiving devices 2 and multiple directional sending modules 12, and the signal pushing device 1 groups the multiple signal receiving devices 2 according to the positions of the multiple signal receiving devices 2, and uses different directional sending modules 12 to send different signals to different grouping areas, so that the signal receiving devices 2 in different groups receive different signals.

[0027] It should be noted that this embodiment is applicable to situations of multi-person international conferences. People of different nationalities wear different signal receiving devices 2, are grouped and positioned, and sound signals in different languages ​​are transmitted to different group areas, so that different sounds can be heard in different areas without wearing headphones.

[0028] Furthermore, after grouping, when a group of users moves as a whole, the directional sending module 12 responsible for the group automatically adjusts the signal sending direction so that the group can receive directional signals; if individual users in a group move into the area of ​​other groups, the user is automatically removed from the group and added to the group in its area, so that the user can continue to receive new signals without affecting the signal coverage of the group originally in which it is located; if the number of users in a group is reduced to 0, the directional sending module 12 of the group is automatically allocated to other groups to improve the efficiency of resource allocation.

[0029] Furthermore, in an embodiment of the present invention, a signal push method based on the location push signal system is also provided, which includes:

[0030] The signal push device establishes a spatial coordinate system with itself as the origin, and locates the signal receiving device according to the electronic positioning tag of the signal receiving device;

[0031] Directional push of set signals towards the direction of the signal receiving device.

[0032] Furthermore, in the signal pushing method, when there are multiple signal receiving devices and directional sending modules, the signal pushing device groups the multiple signal receiving devices according to their positions, and uses different directional sending modules to send different signals to different grouping areas, so that signal receiving devices in different groups receive different signals.

[0033] Furthermore, in the signal push method, when a group of users moves as a whole, the directional sending module responsible for the group automatically adjusts the signal sending direction; if an individual user in a group moves into the area of ​​another group, the user is automatically removed from the group and added to the group in the area where he is located; if the number of users in a group is reduced to 0, the group is automatically deleted and the directional sending module of the group is allocated to other groups.

[0034] To sum up, by adopting the system and method based on location push signals of the present invention, the signal sending device can automatically group users and adjust the signal sending direction according to the location detection tags worn by different users, thereby increasing user convenience; users only need to carry location detection tags and do not need to wear headphones or other equipment, and can move freely in a designated space. It is easy to use and simple to operate, thereby reducing the rate of human damage to the equipment and reducing maintenance costs; the system layout is flexible, and only a number of devices need to be arranged around the venue.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
