Description

Technical Field

[0001] This utility model relates to the field of communications, and more specifically to a very high frequency (VHF) communication system, and also to a portable communication device including the VHF communication system. Background Technology

[0002] In short-term, sudden, or temporary flight test command scenarios, such as during the test flight of a certain aircraft model, the command team needs to maintain real-time communication with the aircraft in the field or on a mountaintop. This necessitates a portable communication device to enable two-way communication between ground command and the test flight crew. Currently, VHF communication is commonly used in the aviation field for communication between the ground and the aircraft. VHF handheld radios exist, but these devices are limited by their size, relatively low transmission power, and short antennas, thus limiting communication distance. Specifically, VHF handheld radios typically include a built-in microphone, a built-in speaker, and a power supply. The microphone receives voice from the user and converts it into analog audio signals, the speaker demodulates the received analog audio signals and converts them back into sound, and the power supply powers the entire VHF handheld radio. However, such VHF handheld radios often only support local radio frequency transceiver, and the communication distance is limited by their own radio frequency performance. Therefore, the application scenarios of these VHF handheld radios are limited, and they are not suitable for scenarios such as field or mountaintop locations.

[0003] Existing technology also includes an aircraft air-to-ground shielded communication system. This system deploys a WLAN access point within the aircraft cabin, through which air marshals or flight attendants carry portable wireless terminals. These terminals connect to the cockpit control panel, and then, via an onboard HF / VHF / UHF or satellite transceiver, enable two-way communication with the mission operations center. However, this communication method is only applicable to the aircraft and not to the ground. Furthermore, the system is relatively dispersed, lacks integrated deployment, and is not miniaturized, thus failing to fundamentally meet the real-time communication needs of command teams in the field or on mountaintops with aircraft undergoing test flights.

[0004] In summary, existing VHF communication equipment is scattered and lacks integration. Furthermore, current field equipment cannot meet the requirements for portable transportation and is not suitable for communication between command teams and test aircraft in field or mountain environments. Utility Model Content

[0005] This invention was made in view of the above-mentioned problems, and its purpose is to provide a very high frequency voice wireless communication system and a portable communication device including the very high frequency communication system.

[0006] This utility model provides a VHF communication system for communicating with the test flight crew via VHF, including:

[0007] A microphone used to collect sound waves and convert them into analog audio signals;

[0008] The earpiece is used to convert received analog audio signals into sound waves;

[0009] The voice transceiver module is used to digitize and encode analog audio signals sent from the microphone and send them to the wireless transmission module, or to decode digital audio signals received by the wireless transmission module into analog audio signals and send them to the earpiece.

[0010] The communication control module is used to allocate radio resources to the voice transceiver module that can communicate with the aircraft crew via VHF, and to configure the operation information of the radio resources.

[0011] A wireless transmission module includes a voice channel and a control channel. The voice channel is used for transmitting digital audio signals between the voice transceiver module and the radio resource. The control channel is used for transmitting operational information and the radio resource's operating status information between the communication control module and the radio resource.

[0012] Power supply, which is used to power VHF communication systems.

[0013] By integrating the voice transceiver module, communication control module, wireless transmission module, power supply, microphone, and earpiece in a functionally coupled manner, bidirectional real-time transmission of voice signals in the VHF band is achieved. The voice transceiver module completes the sound-to-electric / electric-to-voice conversion, and the communication control module centrally schedules radio resources, avoiding the signal delay and power consumption redundancy caused by traditional discrete components.

[0014] This invention also provides another implementation of a VHF communication system, in which radio resources include a receive signal threshold and a transmit power.

[0015] This invention also provides another implementation of a VHF communication system, which includes a control panel capable of controlling the information and power supply of radio resources. The control panel directly maps radio resources to the power switch via physical buttons or knobs, enabling rapid adjustment of radio resources and also supporting a "one-button talk" mode, i.e., PTT mode.

[0016] This invention also provides another implementation of a VHF communication system, wherein the voice transceiver module further includes an audio processing module, which is used to optimize digital audio signals and / or analog audio signals.

[0017] By adding an audio processing module, the common "howling" problem in VHF communication is effectively solved, ensuring the clarity of voice communication with the test aircraft in noisy environments.

[0018] This invention also provides another VHF communication system in which a 4G module and / or a 5G module and / or a Wi-Fi module are integrated in the wireless transmission module.

[0019] By using the aforementioned communication modules, the VHF communication system can be networked with a remote base station. This allows the VHF radio resource information configured by the communication control module and the voice information transmitted by the voice transceiver module to be sent to the remote base station. The remote base station then configures a VHF radio based on this radio resource information to send the voice information to the communication target, thus achieving VHF communication.

[0020] The present invention also provides a portable communication device, which includes any of the aforementioned VHF communication systems. The portable communication device also includes a housing in which the aforementioned VHF communication system is housed.

[0021] This invention also provides another portable communication device, which includes a pull rod and wheels. The pull rod is mounted on one side of the housing, and the wheels are mounted on the bottom of the portable communication device, i.e., the bottom of the housing. By extending the pull rod and using it in conjunction with the wheels, the portable communication device can be dragged and moved by a single person, saving manpower.

[0022] This invention also provides another portable communication device, which further includes a display unit for displaying available remote base station information and power information.

[0023] This invention also provides another portable communication device, which further includes a carrying system that makes the portable communication device easy to carry and transport. Preferably, the carrying system can be implemented as a shoulder strap. The carrying system or shoulder strap makes the portable communication device suitable for scenarios such as the wilderness where dragging is inconvenient, allowing users to achieve portable movement.

[0024] The above-described implementation method, through modular design and application scenario expansion, can cover the needs of fixed stations, vehicle-mounted and portable scenarios, and solves the pain points of traditional VHF communication equipment such as discrete design, complex operation and poor environmental adaptability. In particular, it can meet the needs of emergency rescue, military communication, field operation or flight test command communication and other fields. Attached Figure Description

To make the solution of this utility model clearer, the utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Figure 1 This is a schematic diagram of a VHF communication system according to the present invention. Figure 1 As shown, the VHF communication system 1 includes a voice transceiver module 2, a communication control module 3, a wireless transmission module 4, a microphone 6, and a handset 7. The communication control module 3 is responsible for configuring the necessary information for VHF communication between the remote base station 8 and the communication target 9, including frequency, transmission power, modulation method, and signal threshold. The main function of the voice transceiver module 2 is to receive the audio signal (analog signal) collected from the microphone and to modulate or encode the analog or digital signal received from the wireless transmission module 4 before transmitting it to the handset. The wireless transmission module 4 is equipped with a 4G module and / or a 5G module and / or a Wi-Fi module. These modules enable data transmission and reception without relying on physical cables, such as network cables, and can access operator networks, i.e., the Internet or specific communication networks. The wireless communication module can communicate with the remote base station 8 through the operator network and can send the audio signal to be transmitted (analog or digital signal) and the relevant configuration information of the VHF communication radio resources configured by the communication control module 3 to the remote base station 8. The remote base station 8 is configured according to the relevant configuration information received from the VHF communication system 1, and VHF communication between the remote base station 8 and the communication target 9 is realized based on this configuration information. This indirectly realizes communication between the VHF communication system and the communication target 9, i.e., the test aircraft. Conversely, when the VHF communication system 1 receives the audio signal (analog or digital signal) from the test aircraft, the audio signal from the aircraft, i.e., the communication target 9, is first transmitted to the remote base station 8 via VHF communication configured according to previous radio resources. After receiving the audio signal, the remote base station 8 processes it and transmits it to the VHF communication system 1, i.e., the wireless transmission module 4, via the operator network. The wireless transmission module transmits the audio signal to the voice transceiver module 2, and finally, the analog or digital signal is converted into sound via the earpiece 7. This communication method overcomes the communication difficulties between the test aircraft and the ground. In addition, the VHF communication system 1 also includes a power supply 5, preferably a UPS power supply. This power supply provides uninterrupted power to components within the system that require power, such as the voice transceiver module 2, the wireless transmission module 4, the microphone 6, and the earpiece 7.

[0041] Figure 2 This is a schematic diagram of an alternative embodiment of the VHF communication system according to this utility model. For example... Figure 2 As shown, the VHF communication system 1 also includes a control panel 10. Users can control and configure the communication system through this control panel, such as configuring relevant VHF configuration information, i.e., adjusting the frequency, transmission power, modulation method, or signal threshold.

[0042] Preferably, the voice transceiver module 2 also supports a one-button call mode (PTT mode), enabling real-time control of voice transmission. When the user presses a button on the control panel or operating handle, they can communicate directly with any communication target, i.e., the test aircraft, in a "one-to-one" or "one-to-many" manner.

[0043] Figure 3 This is a schematic diagram of another embodiment of the VHF communication system according to this utility model. (See diagram below.) Figure 3 As shown, the VHF communication system 1 also includes an audio processing module 21. This audio processing module 21 is integrated into the voice transceiver module 2 and is used to perform noise reduction, echo cancellation, and other processing on the sound signal to improve the local voice quality.

[0044] Figure 4 This is a schematic diagram of a portable communication device including the VHF communication system according to the present invention. Figure 4 As shown, the portable communication device 100 includes a VHF communication system 1 and a housing 11. The VHF system 1 is integrated inside the housing 11 and includes a voice transceiver module 2, a communication control module 3, a wireless transmission module 4, and a power supply 5. The portable communication device 100 also includes a microphone, a handset, a control panel, and a display unit, which are not shown in the figures for simplicity. Preferably, the control panel is located on the housing 11 of the portable communication device 100 and is used to configure communication and display relevant information on the display unit. Alternatively, the microphone and / or handset can be integrated into the housing 11 of the portable communication device 100 or can be separate and connected to the portable communication device 100 during use.

[0045] like Figure 4 As shown, the portable communication device according to this utility model also includes a telescopic rod 12 and rollers (not shown). The rod 12 is disposed on one side of the portable communication device 100, and the rollers are disposed on the bottom of the portable communication device 100. When the user needs to move the portable communication device, the user can extend the telescopic rod and use it in conjunction with the rollers to achieve efficient dragging without lifting the communication device. In addition, the portable communication device 100 also includes a carrying system 13, which is disposed on one side of the portable communication device 100. Preferably, the carrying system 13 can be implemented as a shoulder strap. When the user needs to carry the communication device for movement, they can carry it using the carrying system 13, for example, for movement in areas with uneven terrain, effectively meeting the terrain needs of field experiments or operations.

[0046] The implementation of this utility model is not limited to the embodiments described above, and can be adjusted and optimized according to different design requirements and usage environments. The scope of protection of this utility model should be determined by the content of the claims, and not limited to the embodiments described above. Although this utility model has been described through specific embodiments, any modifications, changes, and combinations made by those skilled in the art to various embodiments and implementation methods of this utility model without departing from the spirit of this utility model should be within the scope of protection of this utility model.
