[0039] The present application provides a multifunctional receiver and amplifier and an audio broadcasting system, which can be applied to the technical field of receiver and amplifier. Figure 1 , Figure 1 A schematic diagram of the structure of a multifunctional receiver and expander provided in an embodiment of the present application is shown. Figure 1 As shown, the multifunctional receiving and expanding machine in the embodiment of the present application includes:

[0040] Sweep frequency RDS receiving module, communication module, audio filter, audio output module, control module, ARM network module, camera module and night vision module;

[0041] The frequency sweeping RDS receiving module is used to receive broadcast signals sent by wireless broadcasting stations, and the frequency sweeping RDS receiving module is connected to the audio filter and the control module; the communication module is used to receive broadcast signals sent by a cloud network broadcasting platform, and the communication module is connected to the audio filter and the ARM network module; the ARM network module is connected to the audio filter and the control module;

[0042] The camera module is used to collect image data around the multifunctional receiver and expander, and the camera module is connected to the ARM network module to transmit the image data to the ARM network module; the night vision module is used to provide fill light for the camera module;

[0043] The audio filter is connected to the audio output module.

[0044] In an embodiment of the present application, the multifunctional receiver and expander includes a sweep frequency RDS receiving module, a communication module, an audio filter, an audio output module, a control module, an ARM network module, a camera module and a night vision module. Among them, the sweep frequency RDS receiving module is a module for receiving RDS (Radio Data System) signals sent by a radio station. RDS is a technology for transmitting additional information through FM broadcast signals, which can provide information about the station name, song information, traffic information, etc. The sweep frequency RDS receiving module can help the receiver and expander receive and decode these additional information, thereby improving the user's listening experience. For example, a wireless radio station or a broadcast center can publish a broadcast signal, and the sweep frequency RDS receiving module can receive the transmitted broadcast signal. On the one hand, the sweep frequency RDS receiving module can be connected to the control module, the control module can perform RDS decoding on the audio, and the relevant parameters of the sweep frequency RDS receiving module can be set through the control module; on the other hand, the sweep frequency RDS receiving module can be connected to the audio filter, and after filtering the received broadcast signal through the audio filter, it can be output to the audio output module for playback. In the embodiment of the present application, a scanning RDS receiving module is used, and the multifunctional receiver and amplifier can set multiple receiving frequencies, and can give priority to broadcasting according to the emergency situation of the channel, or use some channels as backup channels. If a transmitting station is broken, it can switch seamlessly, thereby improving the reliability of broadcasting.

[0045] In the embodiment of the present application, in addition to playing the broadcast signal sent by the wireless broadcasting station, a communication module is also provided in the multifunctional receiver and expander, and the communication module can be connected to the cloud network broadcasting platform for receiving the broadcast signal sent by the cloud network broadcasting platform. Specifically, the communication module can include at least one of a wired communication module, a wireless communication module, a mobile communication module, and a LoRa module.

[0046] In the embodiment of the present application, the communication module can be connected to the ARM network module and the audio filter. Similarly, the ARM network module can decode the broadcast signal received by the communication module, and then the 6777 can send the broadcast signal to the audio filter. After filtering the received broadcast signal by the audio filter, it can be output to the audio output module for playback. In the embodiment of the present application, the ARM network module is a module that integrates an ARM processor and a network interface. It is a low-power, high-performance processor architecture that is widely used in various embedded systems and mobile devices. By integrating the ARM processor and the network interface, the ARM network module can realize the network connection of the device, including wired or wireless network connection, such as Ethernet, Wi-Fi, Bluetooth, etc., so that the device can be connected to the Internet, and functions such as remote control, data transmission, and firmware upgrade can be performed.

[0047] In an embodiment of the present application, relevant AI analysis and broadcast functions can be integrated in the ARM network module. Specifically, the multifunctional receiver and expander includes a camera module for collecting image data around the multifunctional receiver and expander. The camera module is connected to the ARM network module to transmit the image data to the ARM network module. The ARM network module can perform video analysis on the image data, and according to the content of the analysis, retrieve the corresponding audio source pre-stored in the ARM network module for broadcasting, or call the received broadcast signal for playback. It should be noted that part of the algorithm in the ARM network module belongs to the existing technology. For example, the public patent CN110363956A mentions a video analysis algorithm combined with an alarm system of intelligent broadcasting. In an embodiment of the present application, the relevant algorithms involved therein can be used to realize the above-mentioned AI analysis and broadcast functions. This application only uses relevant hardware to complete the construction of the equipment and does not involve improvements to the algorithm.

[0048] It should be noted that in the embodiment of the present application, the camera module may be able to collect relatively accurate image data during the day, but at night, due to the relatively dim light, it may not be able to collect clear video or the recognition is poor. Therefore, in the embodiment of the present application, a night vision module is additionally provided in the multifunctional receiver and expander, and the night vision module can provide supplementary light for the camera module at night.

[0049] Specifically, in some embodiments, the night vision module may include a photosensitive sensor and an LED light group. Figure 2 , Figure 2 A circuit principle diagram of a night vision module provided in an embodiment of the present application is shown. In the embodiment of the present application, a night vision module can be built using a photosensitive sensor and an LED light group. The photosensitive sensor can detect the brightness of the environment and change its own resistance according to the brightness, thereby adjusting the working state of the LED light group to achieve fill light operation for the camera module at night.

[0050] In some embodiments, the audio output module includes an audio power amplifier output module and an external power amplifier output module. The audio power amplifier output module can directly output the amplified audio data, and the external power amplifier output module can be connected to a horn or a speaker column to output the sound.

[0053] In the embodiment of the present application, the multifunctional receiver and expander may further include a USB Bluetooth serial port parameter setting module, and the frequency and partition control code of the RDS FM reception may be parameterized through the USB Bluetooth serial port parameter setting module. In addition, an indicator light module may be included, and the indicator light module may be used to indicate the working status of the multifunctional receiver and expander, for example, the indicator light is always on after receiving a broadcast signal, and it is slow flashing when in standby mode, and the present application does not limit this.

[0054] In an embodiment of the present application, an audio broadcasting system is also provided, including a wireless broadcasting station, a cloud network broadcasting platform and the aforementioned multifunctional receiver and amplifier. Figure 1 Among them, the wireless broadcasting station is communicatively connected with the frequency sweeping RDS receiving module for transmitting broadcasting signals to the frequency sweeping RDS receiving module; the cloud network broadcasting platform is communicatively connected with the communication module for transmitting broadcasting signals to the communication module.
