[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] See Figure 1 to Figure 2 The present invention provides a variety of signal synthesis and WIFI transmission sharing devices, including a base 1, a sharing device main body 2 and a PCB board 3. The PCB board 3 is fixedly installed in the sharing device main body 2, and the PCB board 3 is integrated with a forwarding 4, frequency synthesizer 5, dual radio frequency WiFi module 6, signal amplifier 7, broadcast channel module 8, GPS module 9, LTE module 10 and embedded processor 13, the PCB board 3 is equipped with a battery 12, the One side of the sharing device main body 2 is provided with a Console interface 11, an SD card slot 16, a USB2.0 interface 17, a SIM card slot one 21, a SIM card slot two 22, and a 10/100M Ethernet port 23. The sharing device main body 2 The top of the shared device body 2 is provided with a WiFi antenna interface 14 and a charging interface 18, the bottom of the sharing device body 2 is provided with an LTE antenna interface 15 and a GPS antenna interface 20, and the other side of the sharing device body 2 is provided with an HDMI interface 19, so Support legs 24 are fixedly installed at the corners of the base 1, and suction cups 25 are installed on the support legs 24.

[0021] In this embodiment, the signal amplifier 7 is electrically connected to the broadcast channel module 8, and the LTE module 10 is electrically connected to the LTE antenna interface 15, the SIM card slot one 21, and the SIM card slot two 22.

[0022] Further, the battery 12 is connected to the repeater 4, the frequency synthesizer 5, the dual radio frequency WiFi module 6, the signal amplifier 7, the broadcast channel module 8, the GPS module 9, the LTE module 10, and the embedded processor 13 respectively through the power supply circuit. Sexual connection.

[0023] Further, the embedded processor 13 is electrically connected to the repeater 4, the signal amplifier 7, the GPS module 9, the LTE module 10, the HDMI interface 19, the Console interface 11, the SD card slot 16 and the 10/100M Ethernet port 23, respectively. connection.

[0024] Further, the transponder 4 is electrically connected to the frequency synthesizer 5, the frequency synthesizer 5 is electrically connected to the dual radio frequency WiFi module 6, and the dual radio frequency WiFi module 6 is electrically connected to the WiFi antenna interface 14, so The GPS module 9 is electrically connected to the GPS antenna interface 20.

[0025] Through the above structure, after the multiple signals are combined to start the WIFI transmission and sharing device, the digital TV TS stream and PS stream are received through the broadcast channel module 8. The embedded processor 13 controls the transponder 4 to transcode the TS stream and PS stream, and send To the frequency synthesizer 5, connect to other multimedia through the HDMI interface 19 and the USB2.0 interface 17, the embedded processor 13 controls the transponder 4 to transcode the video signal, and sends it to the frequency synthesizer 5 through the SIM card of the LTE module 10. Slot one 21 and SIM card slot two 22 or 10/100M Ethernet port 23 receive the cellular network or the Internet network, and are processed by the transponder 4 and sent to the frequency synthesizer 5. The frequency synthesizer 5 deals with various signals from the amplitude and phase relationship of the signal. The signal is frequency synthesized to form a high-definition frequency source with a certain frequency interval, and then forwarded through the dual-radio WiFi module 6. On the one hand, it can meet the needs of watching TV on various portable mobile terminals without a fixed location and will not increase traffic consumption. Realize playback sharing, which can meet the simultaneous reception of multiple people. On the other hand, it can realize mobile WiFi sharing. The dual radio frequency WiFi module 6 enables users to use any combination of dual 2.4G, dual 5.8G, etc., to flexibly customize coverage solutions, which can effectively solve each This kind of internal signal is difficult to cover evenly, with GPS positioning function.

[0026] Preferably, this embodiment also has the following configuration. The USB 2.0 interface 17 is electrically connected to the storage battery 12 and the embedded processor 13 through a power supply circuit and a data transmission circuit, respectively.

[0027] Further, the storage battery 12 is electrically connected to the charging interface 18 through a charging circuit.

[0028] In addition, this multi-signal synthesis and WIFI transmission and sharing device can also read the video files stored in the SD card, after being processed by the transponder 4, sent to the frequency synthesizer 5 to synthesize the signal source with other signals, and then pass the dual radio frequency WiFi Module 6 forwarding can meet the requirements of watching local videos on various portable mobile terminals. It supports battery 12 power supply mode and POE power supply mode. It has strong adaptability, and the cooperation of external support legs 24 and suction cups 25 can effectively increase its use. stability.

[0029] In addition, it should be understood that although this specification is described in accordance with the implementation manners, not each implementation manner only includes an independent technical solution. This narration in the specification is only for clarity, and those skilled in the art should consider the specification as a whole The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
