Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figure 1 and Figure 2 As shown in the figure, this application embodiment provides a switchable control handle for single and dual terminals based on Beidou short message, including: a processing unit, a display unit, an audio unit, an interface unit, and a power supply unit.

[0035] The power supply unit is electrically connected to the processing unit, the display unit, the audio unit, and the interface unit, respectively; the processing unit is electrically connected to the display unit, the audio unit, and the interface unit, respectively; and the audio unit is electrically connected to the interface unit.

[0036] The display unit is configured to provide an application settings interface for users to select either a single-terminal mode or a dual-terminal mode for BeiDou short messages.

[0037] The processing unit is configured to: set or switch to the corresponding single-terminal mode or dual-terminal mode according to the user's selection on the display unit, run the operating system and message parsing software, and control the audio unit to provide voice prompts.

[0038] The display unit is also configured to provide message editing input for the operating system and a message parsing display interface for the message parsing software.

[0039] The audio unit is configured to provide voice prompts under the control of the processing unit.

[0040] The interface unit is configured to provide level conversion for interactive data between the Beidou terminal device and the processing unit.

[0041] like Figure 2 As shown, the display screen corresponds to the display unit, the speaker corresponds to the audio unit, the outer shell and back cover house the processing unit, audio unit, interface unit, and power unit, the buttons correspond to the operation buttons of the processing unit, the motherboard integrates the processing unit, audio unit, and power unit, and the connector corresponds to the interface unit. Specifically, it adopts an upper and lower cover box structure with a 6-inch LCD screen, conforming to ergonomic principles. Considering the product's operating environment, the outer shell, back cover, and cover-like parts are all made of aluminum alloy. Aluminum alloy has good strength and corrosion resistance, good compressive strength, and excellent processing performance, belonging to high-tech, modern, and green products. Furthermore, it has low density and high specific strength, making it a relatively mature lightweight, high-strength alloy material that reduces the overall weight of the product while meeting strength requirements. The power switch and volume control buttons are located on the left side to prevent accidental operation and improve safety and reliability during use; the external interface connector is located below the handle for easy insertion and removal. Heat from the internal motherboard is dissipated through conduction via the back cover. Because the outer shell is made of high-quality thermally conductive aluminum alloy, heat can be directly conducted to dissipate heat to the external environment. The handle has anti-slip grooves on both sides to prevent the terminal from slipping during use.

[0042] For example, the processing unit is designed with a switching switch, which is used to switch between single-terminal mode and dual-terminal mode of BeiDou short message.

[0043] Specifically, the processing unit mainly consists of a processor, memory, etc.; it is responsible for running the operating system and message parsing software, and also for controlling the buzzer to sound.

[0044] Specifically, the switch design allows users to easily switch the operating mode of the control handle according to their actual needs. For example, in environments with good signal coverage, a single-terminal mode can be selected to reduce costs and power consumption; in environments with no network coverage or unstable signals, a dual-terminal mode can be selected to improve communication stability and reliability.

[0045] In addition, the present invention also provides a software system that is compatible with the control handle, which is used to realize the communication protocol, data encoding and decoding, error detection and correction and other functions between the handle and the Beidou short message terminal, so as to ensure the accuracy and reliability of communication.

[0046] For example, the display unit is a touch screen, which is provided with a heating module and an electromagnetic shielding film.

[0047] Specifically, in this embodiment, the display unit uses a 6-inch LED display screen. The touchscreen supports multi-touch and glove mode. During motherboard design, the touchscreen's I / O... 2 The C interface connects to the I / O interface of the processing unit. 2 The C3 interface. The processing unit controls an independent low-dropout regulator to provide power to the touchscreen, outputs GPIO pin signals as touchscreen reset signals, and simultaneously inputs the touchscreen's interrupt signal to a pin with external interrupt functionality to ensure interrupt signal response. Additionally, the screen incorporates heating and electromagnetic shielding to enable stable operation in extreme temperature and electromagnetically complex environments.

[0048] For example, the audio unit has two audio outputs. The first audio output drives the local speaker, and the second audio output drives the communication device through the interface unit.

[0049] Specifically, in this embodiment, the audio circuit has two audio outputs: one output drives the local speaker, and the other outputs through the interface unit to drive the headphones (i.e.,...). Figure 1 (The device is a communication device). Two audio outputs are independently controlled, allowing for individual or simultaneous output. One differential audio output goes to an audio amplifier to drive an 8-ohm speaker. The speaker is controlled by controlling the output audio source and the audio amplifier. The processing unit's output audio source goes to a headphone driver, which drives an external communication headset via a connector. The processing unit controls the communication headset by controlling the output audio source and the headphone driver (via GPIO pins).

[0050] For example, the interface unit includes two RS422 transceiver chips, one RS232 transceiver chip, and one audio interface.

[0051] Two RS422 transceiver chips are used to provide level conversion for interactive data between the Beidou terminal device and the processing unit.

[0052] An RS232 transceiver chip is used to provide software upgrades and self-testing for the processing unit.

[0053] An audio interface is provided for connecting the audio unit to an external communication device.

[0054] Specifically, the UART6 and UART7 interface signals of the processing unit are at LVCMOS18 level. These two sets of UART interface signals are converted to LVCMOS33 level UART signals by a level conversion chip. After level conversion, the two sets of UART signals are each converted to RS422 serial port signals by an RS422 transceiver chip and then sent to the Beidou terminal equipment (i.e.,...). Figure 1 The terminal unit supports USB 2.0 and USB 3.0 protocols in its processing unit and can output directly through the RS232 transceiver chip in the interface unit. It also supports software upgrades and self-testing (i.e.,...). Figure 1 (Upgrades and maintenance in progress).

[0055] For example, the external airborne power supply is filtered by a surge suppressor and a filter before being connected to the power supply unit for voltage conversion.

[0056] Specifically, the power supply adopts a DC +28V input (i.e. Figure 1 The onboard power supply (using a surge suppressor and filter) is converted to +4.2V by the power supply unit; one 4.2V supply directly powers the processing unit, audio unit, etc.; another 4.2V supply is converted to 3.3V by a voltage regulator (model SGM2211) to power the interface unit; another 4.2V supply is converted to 2.8V by a voltage regulator (model SGM2036) to power the processing unit; another 4.2V supply is converted to 1.85V by a voltage regulator (model SGM2036) to power the processing unit, audio unit, and display unit; and another 4.2V supply is converted to 2.8V by a voltage regulator (model SGM2036) to power the display unit.

[0057] Specifically, such as Figure 3 As shown, Figure 3 The left side shows the single-terminal sending and receiving interface, and the right side shows the dual-terminal sending and receiving interface. Users can find the "Terminal Mode" option in the application settings interface, select "Single Terminal" or "Dual Terminal," and after confirming the selection, the system will switch modes and indicate a successful switch. In single-terminal mode, the interface unit establishes a communication connection with the BeiDou terminal device through the BeiDou short message handle to achieve data sending and receiving. In dual-terminal mode, the control unit can simultaneously establish communication connections with two BeiDou short message terminals, enabling parallel data processing and transmission.

[0058] This application embodiment also provides the above-mentioned working method of the single / dual terminal switchable control handle based on Beidou short message, including the following steps: Step 1: Initialize the single / dual terminal switchable control handle based on BeiDou short message service.

[0059] Step two: Users select either single-terminal or dual-terminal mode for BeiDou short messages through the application settings interface.

[0060] Step 3: The processing unit sets or switches to the corresponding single-terminal mode or dual-terminal mode according to the user's selection, runs the operating system and message parsing software, and establishes a communication link with the Beidou terminal equipment.

[0061] Step four: Based on the BeiDou short message single / dual terminal switchable control handle, send and receive BeiDou short message data. The data to be sent is input by the message editing input function of the operating system, and the data to be received is displayed by the message parsing display interface of the message parsing software.

[0062] Step 5: When a mode switch is required, the Beidou short message single / dual terminal switchable control handle will interrupt the current communication, reconfigure and establish a new communication link.

[0063] The embodiments of this application achieve flexible switching between single-terminal and dual-terminal modes for BeiDou short messages through the collaboration of a processing unit, a display unit, an audio unit, an interface unit, and a power supply unit, which can meet the communication needs in different environments.

[0064] The proposed processing unit is designed with a switching switch, which is used to switch between single-terminal mode and dual-terminal mode for BeiDou short messages. Users can easily switch the working mode of the control handle, which improves the ease of use and flexibility of the equipment.

[0065] The proposed touch display screen is equipped with a heating module and an electromagnetic shielding film, enabling the display unit to operate stably in extreme temperature and electromagnetically complex environments.

[0066] The proposed audio unit has two audio outputs. The first audio output drives the local speaker, and the second audio output drives the communication device through the interface unit, which improves the flexibility of audio output.
