Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a novel radio station intelligent panel. Background Art

[0002] Traditional radio stations only have a small character-type OLED display and a small number of buttons, so it is very inconvenient for users to operate the radio in practice. They need to press multiple buttons and control menus to complete the configuration of working parameters, and they need to press multiple buttons and the radio's built-in pinyin input method to edit short messages and view the content of short messages. They need to press the PTT button when speaking to send out what they say, so the use efficiency of traditional radio stations is very low. Summary of the invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a new type of radio intelligent panel, which can be embedded on the outside of a traditional radio control panel, connected to the radio through a radio interface and powered by the radio, and can configure the radio working parameters, edit, send and play short messages according to user voice commands. In addition, half-duplex voice communication can be carried out without pressing the PTT button, thereby improving the use efficiency of traditional radio stations.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0011] Furthermore, the application software includes a direction of arrival estimation algorithm, a beamforming algorithm, an offline speech recognition algorithm and a voice assistant. The direction of arrival estimation algorithm samples the speech of the microphone array, determines the direction of the speech, and reports the direction result to the beamforming algorithm. The beamforming algorithm is used to pre-process the speech samples and send them to the offline speech recognition algorithm. The offline speech recognition algorithm parses the user's instructions through the received speech and sends the instructions to the voice assistant. The voice assistant configures the radio parameters through the serial port, edits and sends short messages, plays the received short messages, and controls the PTT signal to complete half-duplex voice communication according to the user's instructions.

[0019] The embodiments of the present invention will be described in detail below with reference to examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] This embodiment proposes a new type of radio station smart panel, which is fixed on the outside of the radio station control panel and includes an ARM processor. The ARM processor is connected to the radio station, a first speaker, a microphone array and a touch screen respectively. The microphone array is used to extract the user's voice in a noisy environment, the speaker is used to play the execution results of the instructions and the content of the short messages received by the radio station, and the touch screen is used to display the current working status of the radio station and the received short messages.

[0023] This embodiment firstly extracts the user's voice in a noisy environment through microphone array technology, then uses offline voice recognition technology to parse the instructions issued by the user, and configures the radio working parameters, edits, sends and plays short messages according to the user's instructions. In addition, voice activation detection technology can be used to enable the user to conduct half-duplex voice communication without pressing the PTT button, thereby freeing up both hands to engage in other work and improving the use efficiency of traditional radio stations.

[0024] Specifically, the ARM processor is connected to the radio station through a radio station interface, the radio station interface includes an audio interface, a PTT interface and a serial port, and the audio interface includes a power interface, a ground interface, a second speaker interface, and a first microphone interface.

[0025] Furthermore, the second speaker interface, the first microphone interface and the codec of the ARM processor can be disconnected, the PTT interface and the GPIO of the ARM processor can be disconnected, the serial port is connected to the serial port of the ARM processor, and the microphone array and the first speaker are connected via I 2The S interface is connected to the ARM processor, the touch screen is connected to the ARM processor via the MIPI interface, and the second speaker interface, the first microphone interface, the ground interface and the PTT interface are also connected or disconnected with the radio handle respectively.

[0026] In this embodiment, when the new radio smart panel is connected to the radio handle through a connector, the second speaker interface, the first microphone interface, the ground interface and the PTT interface of the radio interface are directly connected to the radio handle, while the connection with the ARM processor is disconnected. That is to say, the machine in this embodiment can satisfy the user's use according to the traditional radio usage method, or choose not to operate manually and use the radio directly through voice to meet the needs of different users.

[0027] Furthermore, the microphone array is composed of four second microphones, each of which is placed at a vertex of a square. The user's voice has a phase difference when it reaches different second microphones, which makes it easy to determine the direction of the voice.

[0028] Furthermore, the Linux operating system runs on the ARM processor, and the application software of the new radio intelligent panel runs in the Linux operating system environment and interacts with various peripherals through drivers.

[0029] Furthermore, the application software includes four parts: a direction of arrival estimation algorithm, a beamforming algorithm, an offline speech recognition algorithm and a voice assistant. The direction of arrival estimation algorithm samples the speech of the microphone array, determines the direction of the speech, and reports the direction result to the beamforming algorithm. The beamforming algorithm is used to pre-process the speech samples and send them to the offline speech recognition algorithm. The offline speech recognition algorithm parses the user's instructions through the received speech and sends the instructions to the voice assistant. The voice assistant configures the radio parameters through the serial port, edits and sends short messages, plays the received short messages, and controls the PTT signal to complete half-duplex voice communication according to the user's instructions.

[0030] In the above embodiments, the method for preprocessing speech samples by the beamforming algorithm is preferably: multiplying each speech sample by a complex excitation coefficient and then adding them.

[0031] The direction of arrival estimation algorithm preferably determines the direction of the speech based on the phase difference when the speech reaches different second microphones.

[0032] The offline speech recognition algorithm preferably compares the received speech with speech features of known commands to parse out the user's commands.

[0033] Although the present invention has been described in detail in this specification by means of general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto on the basis of the present invention. Therefore, these modifications or improvements made without departing from the present invention all fall within the scope of protection claimed by the present invention.
