Description

Technical Field

[0001] The invention belongs to the technical field of wireless internal communication terminals and relates to a wireless internal communication terminal. Background Art

[0002] Wireless internal communication products are widely used in television stations, radio stations, film and television production, theatrical performances, celebrations, firefighting and disaster relief, and other work occasions that require on-site command and coordination. In the above-mentioned on-site command and dispatch occasions, staff often need an internal communication terminal and equipment. This terminal allows all participating staff to speak at the same time, and can be divided into groups and commanded in a hierarchical manner according to the commander's requirements. Only in this way can the command and dispatch, coordination and cooperation between on-site staff be solved. For traditional internal communication systems, the coverage range is small, and the maximum coverage radius of a single system is generally only 2Km. Even with extension lines and cascade methods, the coverage range is still limited. With the large-scale shooting of events such as sports games and performances, more and more people are involved in the production, the division of labor is constantly refined, and the venue of the event is no longer limited to one studio, one theater, one stadium, or one city, but may be multiple studios and multiple sites across provinces and cities; Chinese patent CN110351611A discloses a wireless internal communication system, including a host, which is used to send a control instruction to an extension under a current channel through a dedicated time slot to enable or disable the extension, and send a voice signal through the dedicated time slot, and receive and play the voice signal sent by the extension enabled under the current channel; the extension is used to send a voice signal through the acquired communication time slot when enabled, and receive and play the voice signal sent by other enabled extensions and the voice signal sent by the host through the dedicated time slot. The wireless internal communication system can realize flexible and convenient communication, save time and provide convenience for staff, but it is inconvenient for long-distance communication; and the existing wireless internal communication terminals; first, its control center is generally a communication host, and the system layout requires the host to be separately set up and powered; it is also necessary to pay attention to not blocking the host signal to ensure that the host signal is unobstructed, and the control center cannot be moved at will, the position of the command and control personnel is also limited, and the coverage is limited:

[0003] The second is a simple walkie-talkie terminal. Although there are 4G walkie-talkies on the market, this type of product, except that its coverage is no longer restricted by the local wireless network, has very simple functions. The main problem is that it cannot achieve multi-channel full-duplex.
