Description

Technical Field

[0001] This invention relates to the field of directional sound generation, and more particularly to a system and method for location-based signal delivery. Background Technology

[0002] During international conferences, people from different countries sit in different areas, and due to the presence of simultaneous interpreters, the languages ​​heard in each area are different, requiring different audio to be delivered to different areas.

[0003] Currently, methods for delivering different audio to different users mainly include pre-setting target locations and pushing audio to different areas; and providing different users with independent signal receiving devices such as headphones / information receivers. Pre-setting target locations often requires physically dividing the space for different receivers to avoid sound / information mixing, which has high site requirements, high costs, and is inconvenient to deploy. Providing different users with headphones also presents problems such as high system complexity, high cost, and inconvenience in relocation. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a system and method for pushing signals based on location, thereby enabling targets at different locations to receive different signals, and the system is simple to deploy.

[0005] In this embodiment of the invention, a system based on location-based signal push 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 further includes at least one orientation 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 this embodiment of the 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 this embodiment of the invention, the directional transmission module is an ultrasonic loudspeaker.

[0008] In this embodiment of the invention, when the signal pushing device includes multiple directional sending modules and the directional sending module is an ultrasonic speaker, if the signal receiving device needs to receive sound in a directional manner, the multiple ultrasonic speakers simultaneously send ultrasonic waves to different locations near the signal receiving device according to the location of the signal receiving device, forming stereo sound.

[0009] In this embodiment of the 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 this embodiment of the invention, when there are multiple signal receiving devices, the signal pushing device groups the multiple signal receiving devices according to their locations, and uses different directional sending modules to send different signals to different group areas, so that the signal receiving devices in different groups receive different signals.

[0011] In this embodiment of the invention, when a group of users moves as a whole, the directional transmission module responsible for that group automatically adjusts the signal transmission direction; if an individual user in a group moves into the area of ​​another group, the user is automatically removed from that group and added to the group in the area where the user is located; if the number of users in a group decreases to 0, the directional transmission module of that group is automatically assigned to another group.

[0012] In this embodiment of the invention, a signal pushing method based on the above-mentioned location-based push signal system is also provided, comprising:

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

[0014] The set signal is pushed in the direction of the signal receiving device.

[0015] Compared with existing technologies, the system and method based on location-based push signals of this invention can automatically group users and adjust the signal transmission direction according to the location detection tags worn by different users, increasing user convenience. Users only need to carry location detection tags and do not need to wear headphones or other devices. They can move freely within the designated space, making it convenient and easy to use, thereby reducing the rate of human-caused damage to the equipment and lowering maintenance costs. The system is flexible in layout, requiring only a few devices to be placed around the site. Attached Figure Description

[0021] like Figure 1 As shown in the 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 a signal receiving device 2 with an electronic positioning tag 21.

[0022] together as 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 locate the signal receiving device 2 according to the electronic positioning tag 21 of the signal receiving device 2.

[0023] together as Figure 3 As shown, the signal pushing device 1 further includes at least one directional sending module 12. The directional sending module 12 is used to send a set signal to the signal receiving device 2 according to the location of the signal receiving device 2. When directional sound is required, the signal pushing device 1 sends a directional signal to the location of the signal receiving device 2, thereby preventing other users from receiving the directional signal. This ensures high confidentiality and reduces interference from the directional signal to other users.

[0024] In this embodiment of the 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 transmission module is a signal transmitting device that transmits signals in a specific direction. For example, the directional transmission module can be an ultrasonic loudspeaker that can transmit ultrasonic waves in a specific direction; the directional transmission module can also be an information push device for directional transmission of carrier waves, where the carrier wave can be ultrasonic waves used to carry information. The signal receiving device includes a display screen for displaying information. After receiving the information directionally pushed by the information push device, the signal receiving device decodes it 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 multiple directional sending modules 12, and the directional sending module 12 is an ultrasonic speaker. If the signal receiving device needs to receive sound in a directional manner, the multiple ultrasonic speakers simultaneously send ultrasonic waves to different locations near the signal receiving device according to the location of the signal receiving device to form stereo sound, and adjust the sound direction in real time according to the location of the signal receiving device so that the user is always in the optimal 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. The signal pushing device 1 groups the multiple signal receiving devices 2 according to their positions, and uses different directional sending modules 12 to send different signals to different group 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 multi-person international conferences. People of different nationalities wear different signal receiving devices 2, are grouped and located, and different language sound signals are transmitted to different group areas, so that different sounds can be heard in different areas without wearing headphones.

[0028] Furthermore, after grouping, when the entire group of users moves, the directional transmission module 12 responsible for that group automatically adjusts the signal transmission direction so that the group can receive directional signals. If individual users in a group move into the area of ​​another group, the user is automatically removed from that group and added to the group in their original area, so that the user can continue to receive new signals without affecting the signal coverage of their original group. If the number of users in a group decreases to 0, the directional transmission module 12 of that group is automatically allocated to other groups to improve resource allocation efficiency.

[0029] Furthermore, in this embodiment of the invention, a signal pushing method based on the above-mentioned location-based push signal system is also provided, comprising:

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

[0031] The set signal is pushed in the direction of the signal receiving device.

[0032] Furthermore, in the signal pushing method, when there are multiple signal receiving devices and multiple 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 group areas, so that the 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 that group automatically adjusts the signal sending direction; if individual users in a group move into the area of ​​another group, the user is automatically removed from that group and added to the group in their area; if the number of users in a group decreases to 0, the group is automatically deleted and the directional sending module of that group is assigned to another group.

[0034] In summary, the system and method based on location-based push signals of the present invention can automatically group users and adjust the signal transmission 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 devices. They can move freely within the designated space, making it convenient and easy to use, thereby reducing the rate of human-caused damage to the equipment and lowering maintenance costs. The system is flexible in layout, requiring only a few devices to be placed around the site.

[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 within the protection scope of the present invention.
