Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of VHF airborne radio stations, in particular to a VHF airborne radio station recording circuit with a Beidou timing module. Background Art
[0002] VHF airborne radio is an amplitude modulation airborne voice communication system operating in the frequency band of 118.000MHz to 136.975MHz. It is widely used for two-way voice and data communication between aircraft and ground stations, and between aircraft. VHF airborne radio is mainly used for ground-to-air voice calls, and is suitable for aircraft take-off and landing places such as general aviation airports and offshore helicopter platforms. It is widely used in offshore oil platforms, civil aviation airports, combat airports and other scenes.
[0003] The existing technical solutions have the following main disadvantages in the application of VHF airborne radio stations:
[0004] First, the existing VHF airborne radio is prone to asymmetry in voice communication between the pilot and ground personnel during takeoff and landing, resulting in some important information not being transmitted or processed in a timely manner. This asymmetry is particularly significant in the operation of offshore oil platforms, which may lead to increased operation and maintenance costs and even difficulty in holding people accountable in the event of a major safety accident.
[0005] Secondly, although the existing technology has added a recording function and transmitted it to a secure network for backup, the time records of these recordings still rely on the internal time records of the VHF airborne radio. If a network failure occurs, the time records of the recordings may be wrong, affecting the accuracy and validity of the data.

[0064] Preferably, the user interface includes a touch screen display and a key operation unit.
[0065] The working principle of the utility model is as follows: Beidou timing time acquisition: Beidou timing antenna receives the broadcast signal transmitted by Beidou satellite and sends it to the Beidou timing module (U1) of U1. After the U1 Beidou timing module (U1) parses the received Beidou timing time, it sends the Beidou timing time to the MCU of U2 through the serial port, and the MCU obtains the Beidou timing time.
[0066] Recording acquisition: Voice is input through the microphone to the voice recording module (U3) of U3. The U3 voice recording module (U3) receives and stores the input voice signal, and then transmits the recording information to the MCU of U2 through the USB interface. The MCU then obtains the voice information input by the microphone.
[0067] Voice information and Beidou time processing: In the MCU of U2, the received voice information is combined with the Beidou time to obtain the corresponding voice information content after Beidou time calibration.
[0068] In this way, it can be ensured that no matter which VHF airborne radio station is recording, the voice information will be synchronized with the unified Beidou time, thus ensuring the uniformity of voice recording time.
[0069] Time synchronization accuracy:
[0070] Beidou timing module (U1): The core function of the Beidou timing module is to provide high-precision time synchronization signals. The Beidou receiving unit receives satellite timing signals to ensure accurate and unified time for the entire system.
[0071] Control unit (MCU, U2): MCU receives the timing signal provided by the Beidou timing module through the serial port, generates a synchronization signal through the timing processing unit, and timestamps and processes it with the recording data. This ensures that all recording data has an accurate time stamp.
[0072] Processing and storage of recorded data:
[0073] Voice recording module (U3): This module contains an audio processing unit and a storage unit. The audio processing unit is responsible for receiving and processing the audio signal, while the storage unit is used to store the processed audio signal and its timestamp. This ensures high quality and data integrity of the recording.
[0074] Data compression and transmission: The voice recording module also includes a data compression unit and a data transmission unit, which are used to compress audio data to save storage space and transmit the data to an external storage device through a high-speed data bus to improve data transmission efficiency.
[0075] Recording quality monitoring and abnormal alarm:
[0076] Monitoring unit: This unit monitors the recording quality and time synchronization status in real time, and will sound an alarm if any abnormality occurs, ensuring the reliability of the system and the accuracy of the recording data.
[0077] User Interface and Manual Controls:
[0078] User interface (touch screen display and key operation unit): This interface is used to display the recording status and time synchronization status. Users can manually control and configure through the touch screen and keys, which increases the operability of the system and user experience.
[0079] Efficient data processing and storage:
[0080] Through the high-speed data bus connection, the data transmission between the voice recording module and the control unit is more efficient, reducing the risk of data transmission delay and loss.
[0081] Modular Design:
[0082] Each module (Beidou timing module, voice recording module, control unit) is connected through a standardized interface, which makes the system have good scalability and maintainability, and facilitates subsequent upgrades and functional expansions.
[0083] Precise time stamping capabilities:
[0084] The combination of the precise time signal provided by the Beidou timing module and the recorded data not only improves the accuracy of the recorded data, but can also be used for subsequent data analysis and processing, and has important application value.
[0085] In summary, the VHF air-to-air radio recording circuit with Beidou timing module achieves the main effects of accurate time synchronization, efficient processing and storage of recording data, real-time monitoring and abnormal alarm through the coordinated work of various modules.
