Description

Technical Field

[0001] The present invention belongs to the field of automotive electronic control technology, and specifically relates to a military vehicle command transmission system and method based on coordinated light language control and recognition. Background Art

[0002] With the continuous development of communication technology, command and coordination information on the battlefield can be transmitted accurately, timely and efficiently, so the coordination mechanism and efficiency of different vehicles on the battlefield are constantly being improved and improved. The transmission of information on the battlefield mainly relies on radio communication technology. When the enemy conducts electromagnetic interference or the communication satellite is destroyed, thus affecting the transmission of radio information, or when it is not suitable to use radio communication, the information that relies on radio will not be able to be transmitted accurately, timely and efficiently, thus missing the opportunity and affecting the war situation.

[0003] Currently, some vehicles have built-in LED screens on the outside to display some information. Although the displayed information is relatively intuitive, the content is often limited by the display area and display color and cannot be clearly identified, especially at a certain distance. In addition, the LED display method often cannot achieve the purpose of automatic identification of other devices or vehicles.

[0004] Based on the above situation, the present invention provides a collaborative light language control and recognition system suitable for various military command and combat vehicles. As a supplement to radio communication technology, this system has a simple control loop and reliable performance. It can achieve the purpose of accurately and quickly conveying and automatically identifying specific command information between vehicles in the fleet through different shapes, colors, and on and off combinations of vehicle lights without relying on radio communication technology. Summary of the invention

[0005] The purpose of the present invention is to provide a military vehicle command transmission system based on coordinated light language control and recognition, which solves the problem that combat commands cannot be accurately and timely transmitted due to radio interference on the battlefield.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A military vehicle command transmission system based on collaborative light language control and recognition includes an input unit, a display unit, a control unit, a light pattern acquisition unit and a command light group; the command light group and the light pattern acquisition unit are fixed outside the military vehicle; the input unit, the display unit, the light pattern acquisition unit and the command light group are all connected to the control unit, and the input unit is used for the driver to input control commands; the control unit controls the corresponding lights in the command light group to light up and flash to present a light pattern corresponding to the control command based on the control command input by the input unit; the light pattern acquisition unit is used to acquire image data containing the light pattern of our vehicle; the display unit is used to display the image data acquired by the light pattern acquisition unit, and the driver determines the target vehicle based on the displayed image data.

[0008] Furthermore, the control unit also confirms whether the input control instruction or the parsed control instruction is consistent with the actually executed control instruction.

[0009] Furthermore, the display unit also displays the control instructions being executed by the vehicle.

[0010] Furthermore, the input part includes a plurality of command buttons corresponding to the control instructions, and each command button is provided with a button status indicator light, an execution status indicator light and a signal recognition indicator light. The button status indicator light is used to indicate the usage status of the corresponding command button, the execution status indicator light is used to display whether the control instructions executed by the vehicle controller are consistent with the control instructions actually executed by the vehicle, and the signal recognition indicator light is used to display the corresponding control instructions collected.

[0011] As an implementation method, the command light group is a plurality of visible light sources that can present different colors, shapes and sizes. Different light sources can present patterns of different colors when lit. Each pattern represents a control instruction. The light graphic acquisition unit corresponding to the visible light command light group is an ordinary camera. The ordinary camera collects image data containing the light graphics of our vehicle around the vehicle.

[0012] As another implementation method, the command light group is a plurality of infrared laser sources that can present different colors, shapes and sizes. Different infrared laser sources can present infrared patterns of different colors. Each infrared pattern represents a control instruction. The corresponding camera is an infrared light camera. The infrared light camera collects image data containing the light graphics of our vehicle.

[0013] Furthermore, the control part is a vehicle-mounted control unit, the light pattern acquisition part is a vehicle-mounted camera, the vehicle-mounted camera transmits the recognized light status to the vehicle-mounted control unit via LVDS or vehicle-mounted Ethernet, the display part, the input part and the light group are connected to the control part via hard wire, CAN bus, LIN bus, Ethernet or other buses, and all components of the system are shielded.

[0014] A method for transmitting military vehicle commands based on coordinated light language control and recognition comprises the following steps:

[0015] (1) The driver of vehicle A inputs a control command through the input unit. After receiving the control command, the control unit controls the corresponding lights in the command light group to light up and flash to present a light pattern corresponding to the control command;

[0016] (2) The camera of vehicle B collects image data containing the light pattern of our vehicle and sends it to the display unit for display;

[0017] (3) The driver of vehicle B checks the image displayed on the display unit to determine the target vehicle, and sends the image containing the target vehicle light pattern to the control unit. The control unit parses the target vehicle light pattern to obtain a corresponding control instruction. If the control instruction is inconsistent with the control instruction currently displayed by vehicle B, the signal recognition indicator light of the instruction button corresponding to the control instruction flashes, and the driver of vehicle B presses the instruction button and repeats steps (1) to (3) to continue transmitting the instruction.

[0018] Furthermore, in step (1), when the corresponding command button is pressed in the input unit, the button status indicator light in the command button lights up, indicating that the command button is effectively pressed.

[0019] Furthermore, in step (1), the control unit collects the status of the light source in the command light group, and verifies whether the collected status is consistent with its own driving status, and sends the specific result to the display unit and the execution status indicator light of the corresponding command button for display. Specifically, if they are consistent, the display unit displays that the instruction is correct, and the execution status indicator light 1 on the corresponding command button flashes to show the correct status; if the verification is inconsistent, the display unit displays that the instruction is wrong, and the execution status indicator light 2 on the corresponding command button flashes to show the correct status. After flashing for a certain period of time, the button status indicator light and the execution status indicator light in the corresponding command button are both off, indicating that the instruction has failed to be issued.

[0020] The beneficial effects of the present invention are as follows: (1) The control loop of this system is simple and the performance is reliable. It can accurately and quickly issue and automatically identify specific command information between vehicles in a fleet through different shapes, colors, and combinations of on-off lights on the vehicles without relying on radio communication technology. It can be used in scenarios where radio communication technology is interrupted as a supplement to radio communication technology; (2) The issuance and execution of commands are automatically closed-loop, and the control failure rate is low; (3) Execution data is stored and backed up to facilitate traceability; (4) Data is transmitted over long distances and over a large range through relay and diffusion transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The present invention relates to a structural schematic diagram of a military vehicle command transmission system based on collaborative light language control and recognition. DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and technical solutions.

[0023] Example

[0024] The present invention relates to a military vehicle command transmission system based on collaborative light language control and recognition, comprising an input unit 1, a display unit 2, a control unit 3, a light pattern acquisition unit 4 and a command light group 5; the command light group 5 and the light pattern acquisition unit 4 are fixed outside the military vehicle; the input unit 1, the display unit 2, the light pattern acquisition unit 4 and the command light group 5 are all connected to the control unit 3, the input unit 1 is used for the driver to input control instructions, and is arranged near the driving seat of the vehicle for ease of operation; the control unit 3 controls the corresponding lights in the command light group 5 to light up and flash to present a light pattern corresponding to the control instruction based on the control instruction input by the input unit 1; the light pattern acquisition unit 4 is used to acquire image data containing the light pattern of our vehicle; the display unit 2 is used to display the image data acquired by the light pattern acquisition unit 4, and the driver determines the target vehicle based on the displayed image data.

[0025] Furthermore, the control unit 3 also confirms whether the input control instruction or the parsed control instruction is consistent with the actually executed control instruction.

[0026] Furthermore, the display unit 2 also displays the control instructions being executed by the vehicle.

[0027] It should be noted that the driver inputs the control command by key or voice, preferably by key, and the input unit is a physical key or a virtual key in a touch screen. The display unit is a display screen, and when the input unit is a virtual key, the display unit and the input unit are combined into one, i.e., a touch display screen.

[0028] It should be noted that the input unit includes multiple command buttons corresponding to control commands, such as a normal command button, a hidden command button, an accelerated passing command button, and a cautious passing command button light. The number and type of command buttons are set according to actual conditions. Each command button is provided with a button status indicator, an execution status indicator, and a signal recognition indicator. The button status indicator is used to indicate the use status of the corresponding command button, such as the indicator light is on when pressed and the indicator light is off when not pressed. The execution status indicator is used to display whether the control command executed by the vehicle controller is consistent with the control command actually executed by the vehicle, such as a green light is displayed if they are consistent, and a yellow light is displayed if they are inconsistent. The signal recognition indicator is used to display the corresponding control command collected.

[0029] As an implementation method, the command light group is a plurality of visible light sources (such as LED light sources, halogen light sources) that can present different colors, shapes and sizes. Different light sources can present patterns of different colors when lit, and each pattern represents a control instruction. The light pattern acquisition unit corresponding to the visible light command light group is an ordinary camera, which collects image data containing the light pattern of our vehicle around the vehicle. Due to the limitations of the visible light transmission distance and the acquisition range of ordinary cameras, this implementation method cannot directly realize long-distance transmission of instructions between two vehicles.

[0030] As another implementation method, the command light group is a plurality of infrared laser sources that can present different colors, shapes and sizes. Different infrared laser sources can present infrared patterns of different colors. Each infrared pattern represents a control instruction. The corresponding camera is an infrared light camera. The infrared light camera collects image data containing the light graphics of our vehicle. Invisible light can avoid being discovered by the enemy, and the laser transmission distance is longer. This implementation method can directly transmit instructions over a long distance between two vehicles.

[0031] It should be noted that the control unit is a vehicle-mounted control unit. Multiple vehicle-mounted control units can be set up as needed so that one of them can be used as a backup when a failure occurs. The light pattern acquisition unit is a vehicle-mounted camera. The vehicle-mounted camera transmits the recognized light status to the vehicle-mounted control unit through LVDS or vehicle Ethernet. The display unit, input unit and light group are connected to the control unit through hard wires, CAN bus, LIN bus, Ethernet or other buses. All components of the system (including connecting harnesses) are shielded to minimize electromagnetic interference in the on-site environment and ensure accurate execution of instructions.

[0032] This embodiment involves a military vehicle command transmission system based on collaborative light language control and recognition, which also includes a storage unit, which stores the work log executed by the system to achieve traceability of information data, and also includes a power supply to provide electrical energy to the entire system.

[0033] A method for transmitting military vehicle commands based on coordinated light language control and recognition specifically includes the following steps:

[0034] (1) The driver of vehicle A inputs a control command through the input unit. After receiving the control command, the control unit controls the corresponding lights in the command light group to light up and flash to present a light pattern corresponding to the control command;

[0035] (2) The camera of vehicle B collects image data containing the light pattern of our vehicle and sends it to the display unit for display;

[0036] (3) The driver of vehicle B checks the image displayed on the display unit to determine the target vehicle, and sends the image containing the target vehicle light pattern to the control unit. The control unit parses the target vehicle light pattern to obtain a corresponding control instruction. If the control instruction is inconsistent with the control instruction currently displayed by vehicle B, the signal recognition indicator light of the instruction button corresponding to the control instruction flashes, and the driver of vehicle B presses the instruction button.

[0037] It should be noted that the image data collected by the camera may contain multiple vehicles of our side, and the driver needs to select one of them as the target vehicle and send the light image displayed by the target vehicle to the control unit;

[0038] (4) Repeat steps (2) and (3) to complete the continued transmission of control instructions.

[0039] Example 1

[0040] A method for transmitting military vehicle commands based on coordinated light language control and recognition specifically includes the following steps:

[0041] (1) When the personnel on vehicle A need to issue a specific control command (such as normal, concealed, accelerated passing, cautious passing, uphill, downhill, pay attention to sharp turn, stop, start, etc.), they press the corresponding command button in the input unit, and the button status indicator light in the command button lights up, indicating that the command button is effectively pressed, and the input unit sends a command button pressing signal to the control unit;

[0042] (2) The control unit receives the control command sent by the command button, and drives the light source corresponding to the command light group to light up and flash to display the corresponding light pattern. The light image corresponds to the control command one by one;

[0043] (3) The control unit collects the status of the light source in the command light group, and verifies whether the collected status is consistent with its own driving status, and sends the specific result to the display unit and the execution status indicator of the corresponding command button for display. Specifically, if they are consistent, the display unit displays that the command is correct, and the execution status indicator (such as a green indicator) on the corresponding command button flashes to show the correct status; if the verification is inconsistent, the display unit displays that the command is wrong, and the execution status indicator (such as a yellow indicator) on the corresponding command button flashes to show the correct status. After flashing for a certain period of time, the button status indicator and the execution status indicator in the corresponding command button are both off, indicating that the command has failed to be issued. The command issuing personnel thereby realize a closed loop of command sending and execution;

[0044] It should be noted that if you need to cancel the command, you can long press the corresponding command button;

[0045] (4) The on-board camera of other vehicles in our fleet (such as vehicle B) collects image data containing the light graphics of our vehicle and sends the collected image information to the display unit for display. The image collected by vehicle B generally includes multiple vehicles. The driver selects a certain vehicle as the target vehicle in the display unit, such as vehicle A. The controller on vehicle B analyzes the light status of the selected vehicle (vehicle A) based on the image, obtains the corresponding control instruction, and checks whether the control instruction is consistent with the driving status being executed by the command light group of its own vehicle. If they are consistent, no processing is performed. Otherwise, the signal recognition indicator light of the command button corresponding to the control instruction flashes to remind the driver that a new instruction has been found. If the analysis results in a normal instruction, the signal recognition indicator light of the normal instruction button flashes;

[0046] (5) The driver of vehicle B checks the command he or she visually recognizes from the light status with the command button that lights up the warning light. If they are consistent, the driver of vehicle B presses the command button corresponding to the flashing signal recognition indicator light and repeats steps (1) to (5) to continue transmitting the command.
