Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.
[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of a vehicle-mounted signpost control system provided in an embodiment of this application. Figure 1 As shown, the vehicle-mounted sign control system 100 includes a liftable sign 110, a main control unit 120, a voice processing unit 130, an execution unit 140, and a safety detection unit 150.
[0021] The term "liftable emblem 110" refers to an emblem mounted on a vehicle that has a lifting function. The liftable emblem has a built-in speaker for playing music and also features a light strip.
[0022] The main control unit 120 is used to execute the vehicle-mounted beacon control method and control each unit in the vehicle-mounted beacon control system 100. For example, the main control unit receives feedback signals from each unit, parses instructions, and outputs control instructions to realize the timing scheduling and logical coordination of each unit. The main control unit 120 can be an STM32F103C8T6 microcontroller, which has rich I / O interfaces and communication protocol support to meet the requirements of multi-unit collaborative control.
[0023] The voice processing unit 130 receives and recognizes the beacon wake-up command and beacon control command, and sends the recognition results to the main control unit 120. The voice processing unit 130 has in-vehicle noise reduction capabilities. The voice processing unit 130 includes an offline voice recognition chip, a microphone array, and a voice synthesis subunit. The voice processing unit 130 has a built-in local wake-up word library and function command library, eliminating the need for cloud network access. The local wake-up word library records preset wake-up words, such as "beacon wake-up" and "beacon retraction." The function command library records preset function control commands for music and lights, such as "play song," "light gradient," and "light blink." Therefore, this application adopts a purely local offline voice recognition solution, which differs from the existing cloud-based wake-up word library architecture and effectively avoids network dependence and response latency issues. The voice processing unit 130 can use the LD3320 offline voice recognition chip, paired with two microphones to form an array, improving voice recognition accuracy. The voice synthesis subunit can use the SYN6288, supporting Chinese voice feedback.
[0024] The execution unit 140 is used to control the liftable beacon according to the control commands issued by the main control unit. The execution unit 140 includes a lifting drive unit, an audio playback unit, and a lighting control unit.
[0025] The lifting drive unit adopts a compact structure and is used to control the raising and lowering of the liftable sign. The lifting drive unit includes a servo motor, a worm gear, and a slider-slide transmission mechanism. The main control unit 120 drives the servo motor to rotate forward, which in turn raises the body of the liftable sign 110 through the worm gear and slider-slide transmission mechanism. When the limit sensor detects that the liftable sign 110 has reached the preset display position, it sends a feedback signal to the main control unit 120, which then controls the servo motor to stop operating.
[0026] The audio playback unit is used to play music and provide voice feedback through a speaker. The audio playback unit includes a local storage subunit (such as an SD card), an amplifier chip, and a miniature speaker embedded inside the retractable sign body. The local storage subunit stores preset music files. The audio playback unit uses a 16GB SD card to store music files, and the amplifier chip is a TDA7388, capable of driving an 8Ω / 1W miniature speaker embedded inside the sign body. A hollow design enhances sound propagation.
[0027] The lighting control unit controls the color and brightness of the light strip, supporting multi-color display and music synchronization. The unit includes an RGB light strip, a PWM controller, and a brightness sensor. The RGB light strip is positioned around the outside of the retractable beacon. The PWM controller adjusts the color, brightness, and switching frequency of the light strip, while the brightness sensor detects ambient light intensity and dynamically adapts the lighting brightness. Specifically, the lighting control unit uses a 5050 type RGB light strip, encircling the entire beacon body. The PWM controller is a PCA9685, supporting 16-channel PWM output, and the brightness sensor is a BH1750, used for real-time ambient light detection.
[0028] The safety detection unit 150 is used to perform safety checks on the control process of the liftable beacon. The safety detection unit 150 includes a current detection subunit and a pressure sensor. The current detection subunit monitors the operating current of the servo motor, and the pressure sensor is located at the top of the liftable beacon body to detect external impact forces. Specifically, the current detection subunit uses an ACS712 sensor, and the pressure sensor uses an FSR402 thin-film pressure sensor, which is located inside the outer protective shell at the top of the beacon.
[0029] The voice processing unit 130, the execution unit 140, and the safety detection unit 150 are all linked with the vehicle CAN bus through the main control unit 120.
[0030] Based on the same inventive concept, this application also provides a vehicle-mounted beacon control method corresponding to the vehicle-mounted beacon control system. Since the principle of the method in this application is similar to that of the vehicle-mounted beacon control system described above in this application, the implementation of the method can refer to the implementation of the system, and the repeated parts will not be described again.
[0031] Please see Figure 2 , Figure 2 This is a flowchart illustrating a vehicle-mounted sign control method provided in an embodiment of this application. Figure 2 As shown in the embodiments of this application, the vehicle-mounted sign control method includes: Step S201: Receive the first recognition result from the voice processing unit for the signpost wake-up command, and update the current state of the vehicle signpost control system based on the first recognition result.
[0032] After the vehicle is powered on, the vehicle-mounted hood ornament control system enters standby mode, and the retractable hood ornament itself is in a preset hidden position. The RGB light strip on the retractable hood ornament is turned off, and the voice processing unit enters low-power monitoring mode, only responding to local wake-up words.
[0033] In response to a signpost wake-up command, such as when the driver issues the wake-up word "signpost wake-up", the voice processing unit receives the signpost wake-up command, identifies the signpost wake-up command, matches the wake-up word in the signpost wake-up command with the preset wake-up words in the local wake-up word library, and determines whether there is a preset wake-up word in the local wake-up word library that matches the wake-up word in the signpost wake-up command.
[0034] If a matching preset wake-up word exists, a wake-up signal is sent to the main control unit, which then controls the vehicle-mounted hood ornament control system to enter the working state from standby. Simultaneously, the main control unit generates voice feedback information, such as "wake-up," through the voice synthesis subunit and sends this feedback to the driver, awaiting subsequent hood ornament control commands from the driver.
[0035] Step S202: When the vehicle-mounted signboard control system is in operation, receive the second recognition result of the signboard control command from the voice processing unit.
[0036] In response to a signpost control command, such as when the driver issues a signpost control command to "play music", the voice processing unit receives the signpost control command, identifies the signpost control command, matches the control command in the signpost control command with the preset function control commands in the function command library, and determines whether there is a preset function control command in the function command library that matches the control command in the signpost control command.
[0037] If a matching preset function control command exists, the voice processing unit parses the command type of the signpost control command and converts the command type into a command code, which is then sent to the main control unit. The second recognition result includes the command type of the signpost control command.
[0038] In one embodiment, the instruction type includes at least one of the following: a first instruction type for controlling the raising and lowering of the beacon, a second instruction type for controlling music playback, and a third instruction type for controlling the lighting mode.
[0039] Step S203: Determine the target control sequence based on the instruction type and the current position of the liftable beacon, and control the execution unit to execute the target control sequence to control the liftable beacon.
[0040] The following reference Figure 3 This section will introduce the process of determining the target control sequence.
[0041] Figure 3 A flowchart of the steps for determining the target control sequence provided in the embodiments of this application is shown below. Figure 3 As shown, the steps for determining the target control sequence include: Step S301: If the instruction type is the first instruction type, the lifting control operation of the lifting and lowering target is determined as the first target control operation, and the target control sequence is determined based on the first target control operation.
[0042] If the instruction type is the first instruction type for controlling the raising and lowering of the monument, such as the monument control instruction being "raise the monument", then the raising and lowering control operation is determined as the first target control operation. In this case, the target control sequence only includes the first target control operation.
[0043] Step S302: If the instruction type is the second instruction type, when the current position of the liftable sign is not in the preset display position, the lifting of the liftable sign and the music playback control operation are respectively determined as the first target control operation and the second target control operation, and the target control sequence is determined based on the first target control operation and the second target control operation.
[0044] If the instruction type is the second instruction type for controlling music playback, such as the signpost control instruction being "play music", it means that the liftable signpost needs to be raised and music needs to be played. In this case, the raising and lowering control operation is determined as the first target control operation, and the music playback control operation is determined as the second target control operation. At this time, the target control sequence includes the first target control operation and the second target control operation.
[0045] In one embodiment, if the instruction type is the second instruction type and the current position is at the preset display position, it means that music can be played directly without raising the retractable sign. In this case, the music playback control operation is determined as the first target control operation. At this time, the target control sequence only includes the first target control operation for controlling music playback.
[0046] Step S303: If the instruction type is the third instruction type, when the current position of the liftable sign is not in the preset display position, the lifting of the liftable sign and the light control operation are respectively determined as the first target control operation and the second target control operation, and the target control sequence is determined based on the first target control operation and the second target control operation.
[0047] If the instruction type is the third instruction type for controlling the lighting mode, such as the signpost control instruction being "light gradient", it means that the liftable signpost needs to be raised and the lighting needs to be controlled. In this case, the raising and lowering control operation is determined as the first target control operation, and the lighting control operation is determined as the second target control operation. At this time, the target control sequence includes the first target control operation and the second target control operation.
[0048] In one embodiment, if the instruction type is the third instruction type and the current position is at the preset display position, it means that the light can be controlled directly without raising the retractable sign. In this case, the light control operation is determined as the first target control operation. At this time, the target control sequence only includes the first target control operation for controlling the light.
[0049] After the target control sequence is determined, the execution unit can be controlled to execute the target control sequence.
[0050] For example, if the target control sequence includes a first target control operation, then the execution unit executes the target control sequence according to the first target control operation.
[0051] In one scenario, the first target control operation is to raise the liftable sign. The main control unit drives the servo motor to rotate forward, which, through a worm gear and slider-groove transmission mechanism, raises the body of the liftable sign. When the limit sensor detects that the liftable sign has reached the preset display position, it sends a feedback signal to the main control unit, which then stops the motor. Simultaneously, the main control unit acquires the ambient light intensity detected by the brightness sensor and controls the RGB light strip to gradually brighten to a base color that matches the ambient light intensity through the lighting control unit. For example, if the ambient light intensity is high (e.g., greater than the first preset light intensity), the brightness of the RGB light strip is increased to 80% of the preset brightness; if the ambient light intensity is low (e.g., less than the second preset light intensity), the brightness of the RGB light strip is reduced to 50% of the preset brightness.
[0052] For example, if the target control sequence includes a first target control operation and a second target control operation, then the control execution unit executes the target control sequence sequentially, with the first target control operation executed first and the second target control operation executed last.
[0053] In one scenario, the first target control operation is raising the retractable signpost, and the second target control operation is music playback control. If the retractable signpost is not in the preset display position, the raising action is performed first, followed by activating the audio playback unit. The audio playback unit retrieves the music file from the local storage subunit and plays it through the speaker. Simultaneously, the main control unit extracts the audio spectrum data (such as beat and pitch) of the music in real time, dynamically generates a PWM control signal based on the audio spectrum data, controls the RGB light strip to change color with the beat (e.g., blue for low frequencies, green for mid-range frequencies, and red for high frequencies), and controls the RGB light strip to change brightness with the pitch (e.g., higher pitch results in higher brightness; lower pitch results in lower brightness). Therefore, this application can dynamically generate light control signals (PWM control signals) based on audio spectrum data, rather than using fixed rhythm binding or periodic playback logic, enabling real-time adaptation between light and music, and supporting mode switching for greater flexibility.
[0054] In another scenario, the first target control operation is to raise the retractable signpost, and the second target control operation is to control the lighting. If the retractable signpost is not in the preset display position, the raising action is performed first, followed by the activation of the lighting control unit. The lighting control unit operates according to the lighting mode corresponding to the signpost control command. For example, if the signpost control command instructs the RGB light strip to operate in gradient mode, the light strip's colors transition linearly in gradient mode; if the signpost control command instructs the RGB light strip to operate in jumping mode, the light strip flashes at a fixed frequency in jumping mode. Furthermore, the lighting mode can be superimposed with the music control function, meaning that while music is playing, the lights both dynamically change according to the spectrum and respond to mode commands.
[0055] In one embodiment, during the lifting and lowering process of the liftable sign, the current detection subunit and pressure sensor in the safety detection unit monitor the operating current of the servo motor and the external impact force on the liftable sign, respectively, so as to implement safety protection control based on the detected operating current and external impact force.
[0056] Specifically, the system receives the detection results from the safety detection unit and implements safety protection control over the control process of the liftable beacon based on these results. The detection results include the operating current and the impact force experienced by the liftable beacon. Based on the operating current, it determines whether there is any obstruction or jamming during the control process, and based on the impact force, it determines whether there is any external collision during the control process. If obstruction or jamming and / or external collision are present, the drive motor reverses, controlling the liftable beacon to descend to a preset hidden position.
[0057] For example, the current detection subunit compares the operating current with a preset current threshold. If the operating current is greater than the preset current threshold, it is determined that there is an obstruction or jamming. If the operating current is less than or equal to the preset current threshold, it is determined that there is no obstruction or jamming.
[0058] If the current detection subunit determines that there is an obstruction, it sends an obstruction feedback signal to the main control unit. After receiving the obstruction feedback signal, the main control unit drives the servo motor to reverse and controls the lifting beacon to descend to the hidden position. It then sends a message through the voice synthesis subunit: "Obstruction encountered, now retracted."
[0059] The pressure sensor compares the impact force with a preset impact force threshold. If the impact force is greater than the preset impact force threshold, it is determined that there is an external force collision; if the impact force is less than or equal to the preset impact force threshold, it is determined that there is no external force collision.
[0060] If the pressure sensor detects an external force collision, it sends an external force collision feedback signal to the main control unit. After receiving the external force collision feedback signal, the main control unit drives the servo motor to reverse and controls the lifting and lowering stand to the preset hidden position, while simultaneously controlling the light to flash as an alarm.
[0061] In one embodiment, in response to a retractable emblem command, the main control unit drives the servo motor to reverse, causing the retractable emblem to descend to a hidden position. Simultaneously, it controls the RGB light strip to gradually dim and the audio playback unit to stop operating, returning the vehicle emblem control system to a low-power standby state. Alternatively, if the main control unit detects a power outage in the vehicle, it controls the vehicle emblem control system to automatically retract and then shut down.
[0062] The vehicle-mounted signboard control method provided in this application embodiment can determine and execute a target control sequence based on the command type and the current position of the retractable signboard, so as to realize multiple control methods for the retractable signboard. It integrates voice wake-up, command parsing, lifting control, music playback, light rhythm and safety protection into a coordinated control logic, which solves the problem of single function and lack of intelligent interactivity of vehicle-mounted signboards, and enhances the sense of ceremony and personalized experience of vehicle control.
