Description

Technical Field

[0001] This invention relates to the field of photoelectric control technology for intelligent cleaning equipment, and in particular to a dynamic control system and method for ambient lighting on a floor scrubber based on UART communication. Background Technology

[0002] As intelligent cleaning equipment becomes increasingly complex, intelligent floor scrubbers typically come equipped with a power control board to handle core control tasks such as motor drive and sensor data processing. Regarding human-machine interaction, the front of the floor scrubber usually features a panel ambient light and a corresponding photoelectric control system. Existing centralized photoelectric control architectures generally use a single microprocessor to drive the light-emitting devices, and delegate complex lighting effect rendering calculations to the power control board for centralized processing. Simultaneously, existing hardware communication systems rely on ordinary analog level signals to transmit lighting effect control commands between the control module and the light-emitting devices.

[0003] The aforementioned centralized computing architecture and analog-level communication method have technical flaws in actual operation. The main control chip already bears a heavy data processing task; adding additional lighting effect rendering calculations will overload the core processor, leading to excessive computing resource utilization. Furthermore, when the floor scrubber is running, the high-power brushless motor inside the machine radiates high-frequency electromagnetic interference waves into the surrounding physical space. In complex electromagnetic environments, these high-frequency electromagnetic interference waves can easily couple into the cables transmitting analog signals, generating pulse noise and causing waveform distortion in the analog level signals. Taking the powerful cleaning mode with the brushless motor running at high speed as an example, the microcontroller, after receiving the analog electrical signal with accompanying pulse noise, will output an incorrect duty cycle voltage. This output abnormality ultimately causes the light-emitting devices to exhibit irregular flickering and incorrect lighting effects, and causes a time lag in the feedback of the working status, thus significantly reducing the overall reliability of the photoelectric control system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a dynamic control system and method for ambient lighting on floor scrubbers based on UART communication. This invention solves the technical problems of existing ambient lighting control systems for floor scrubbers, which use a single microprocessor to centrally process and drive the light-emitting devices, and which are prone to waveform distortion when transmitting signals using ordinary analog levels in complex electromagnetic environments. This results in excessively high computational resource consumption of the main control chip, as well as irregular flickering and instruction execution errors in the light-emitting devices.

[0010] Furthermore, in the UART communication-based ambient light dynamic control system for floor scrubbers described in this invention, the array drive module transmits the single-line return-to-zero (NRZ) code digital electrical signal to the data input pins of the red, green, and blue LEDs in the first-stage built-in control circuit of the series-connected LED array via the output pins of the display panel.

[0017] To more clearly illustrate the technical solution of the present invention, the drawings used in the embodiments will be briefly introduced below. Obviously, for those skilled in the art, other drawings can be obtained based on the drawings without creative effort.

[0018] Figure 1 This is a flowchart illustrating a method for dynamic control of ambient lighting in a floor scrubber based on UART communication, according to the present invention. Detailed Implementation

[0019] To make the technical solution of the present invention clearer, the present invention will be clearly and completely described below with reference to specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In a first aspect, the present invention provides a dynamic control system for ambient lighting of a floor scrubber based on UART communication, including hardware devices and a control device that establishes a communication connection with the hardware devices. The hardware includes a power control board, a UART data bus, a display panel, and a series-connected LED array; the display panel has a built-in data buffer unit; the power control board is connected to the display panel via the UART data bus; the output pins of the display panel are connected to the input terminals of the series-connected LED array; the series-connected LED array contains transistors. The control device includes: The status acquisition module, configured on the power control board, is used to collect the working level status of the floor scrubber, convert the working level status of the floor scrubber into basic lighting mode instruction codes, and send the basic lighting mode instruction codes to the communication transceiver module. The communication transceiver module, configured on the power control board, is used to receive basic lighting mode command codes, encapsulate the basic lighting mode command codes into serial data frames, and send the serial data frames to the light effect calculation module configured on the display panel via the UART data bus. The light effect calculation module is used to receive serial data frames, parse the serial data frames to obtain basic lighting mode instruction codes, extract dynamic light effect parameters based on the basic lighting mode instruction codes, generate a preset light effect digital stream based on the dynamic light effect parameters, and send the preset light effect digital stream to the data buffer unit for storage. The array driver module, configured on the display panel, is used to read the preset light effect digital stream stored in the data buffer unit, convert the preset light effect digital stream into a single-line return-to-zero code digital signal, and send the single-line return-to-zero code digital signal to the series-connected light-emitting diode array; the series-connected light-emitting diode array receives the single-line return-to-zero code digital signal and adjusts the output current amplitude of the transistor according to the single-line return-to-zero code digital signal to control the light intensity.

[0021] The level monitoring unit configured in the status acquisition module monitors the level signals corresponding to different working modes of the floor scrubber in real time by connecting to the general-purpose input / output pins of the power control board. Taking the floor scrubber in self-cleaning mode as an example, the sensor inside the machine outputs a 3.3-volt high-level signal. After the level monitoring unit collects the 3.3-volt high-level signal, it extracts the high-level change characteristics and sends them to the instruction conversion unit. The instruction conversion unit has a pre-built mapping dictionary. After receiving the high-level change characteristics, it encodes the high-level change characteristics into a hexadecimal value "0xA1", which serves as the basic lighting mode instruction code carrying the self-cleaning status identifier. Subsequently, the communication transceiver module receives the basic lighting mode instruction code and sets the preset baud rate of the UART data bus to 115200 bits per second. At the same time, it adds one low-level start bit, eight data bits, and one high-level stop bit to the hexadecimal value "0xA1", combines and encapsulates them into a complete serial data frame in chronological order, and finally transmits it to the display panel through the UART data bus.

[0022] Upon entering the light effect calculation stage, the protocol parsing unit receives and parses the serial data frame, extracting the specific values ​​of the dynamic light effect parameters. These parameters include a 60 Hz frequency parameter, a 2-second duration parameter, and a color sequence parameter that transitions from pure red to pure blue. After receiving these parameters, the interpolation generation unit calls a linear interpolation algorithm to perform mathematical calculations. Within the 2-second duration, the interpolation generation unit calculates the RGB color values ​​of 120 intermediate transition colors on average between pure red (RGB value 255,0,0) and pure blue (RGB value 0,0,255). Finally, the interpolation generation unit converts the RGB color values ​​of the 120 intermediate transition colors into a brightness adjustment level sequence that controls the pulse width of the voltage, synthesizing and outputting a continuously changing preset light effect digital stream.

[0023] In the drive conversion stage, the array drive module follows a strict time duty cycle protocol to convert the preset luminous efficacy digital stream into a single-line return-to-zero (RZ) code digital signal. For example, the array drive module outputs a high-level pulse, holds it for 0.8 microseconds, and then goes low to represent logic "1," and outputs a high-level pulse, holds it for 0.4 microseconds, and then goes low to represent logic "0." The generated single-line RZ code digital signal is transmitted to the red, green, and blue LEDs in the first-stage built-in control circuit of the series-connected LED array. The red, green, and blue LEDs in the first-stage built-in control circuit intercept the first 24 bits of the cascaded data frame and extract the logic pulse values ​​representing the red, green, and blue brightness. Then, based on the logic pulse values, the base control voltage of the constant current drive transistor inside the LED is changed, thereby linearly adjusting the current amplitude output by the transistor to the light-emitting chip (the adjustment range is set to 0 to 20 mA), achieving precise control of the luminous intensity.

[0024] To establish a reliable status monitoring mechanism, the closed-loop feedback module is equipped with a miniature current detection circuit to collect electrical response characteristic data of the series-connected LED array. Specific electrical response characteristic data includes the real-time total operating current value of the LED array and fault circuit interruption alarm codes. The closed-loop feedback module encapsulates the collected real-time total operating current value into a status feedback data frame and transmits it to the power supply main control board. Upon receiving the data, the power supply main control board compares the rated current value with the real-time total operating current value to determine whether there is a short circuit abnormality in the ambient lighting control system.

[0025] During the online upgrade process, the firmware distribution module encapsulates the new firmware data packet containing the light effect parameter library file and performs polynomial division on all bytes of the firmware data frame using a cyclic redundancy check algorithm to generate a 16-bit communication checksum. This checksum is then appended to the end of the firmware data frame and sent to the display panel. If a power or network interruption occurs during the firmware upgrade process, causing the new firmware data packet to fail to be completely written to the storage medium, the display panel generates a write failure signal. Upon receiving the write failure signal, the firmware distribution module generates a rollback instruction in hexadecimal code form. Upon receiving the rollback instruction, the display panel forcibly modifies the address value of the boot sector pointer in the storage medium, which determines the program startup address, to the absolute address backed up in the initial stable version storage area before the upgrade. After the system is powered back on, the microprocessor executes the old stable program based on the restored boot sector pointer, ensuring the continuous and stable operation of the floor scrubber's interactive system.

[0026] Secondly, please refer to Figure 1 This invention provides a dynamic control method for ambient lighting on a floor scrubber based on UART communication, applied to the aforementioned dynamic control system for ambient lighting on a floor scrubber based on UART communication, comprising: Step 1: The status acquisition module collects the working level status of the floor scrubber, converts the working level status of the floor scrubber into basic lighting mode instruction code, and sends the basic lighting mode instruction code to the communication transceiver module. Step 2: The communication transceiver module receives the basic lighting mode instruction code, encapsulates the basic lighting mode instruction code into a serial data frame, and sends the serial data frame to the lighting effect calculation module through the UART data bus. Step 3: The light effect calculation module receives the serial data frame, parses the serial data frame to obtain the basic lighting mode instruction code, extracts the dynamic light effect parameters according to the basic lighting mode instruction code, generates a preset light effect digital stream according to the dynamic light effect parameters, and sends the preset light effect digital stream to the data buffer unit for storage. Step 4: The array driver module reads the preset light effect digital stream stored in the data buffer unit, converts the preset light effect digital stream into a single-line return-to-zero code digital signal, and sends the single-line return-to-zero code digital signal to the series-connected light-emitting diode array; the series-connected light-emitting diode array receives the single-line return-to-zero code digital signal and adjusts the output current amplitude of the transistor according to the single-line return-to-zero code digital signal to control the light intensity.

[0027] In this invention embodiment, when a smart floor scrubber encounters mechanical malfunctions such as water shortage in the clean water tank or hair entanglement in the roller brush during heavy-duty cleaning, the status acquisition module on the power control board collects the working level status triggered by the water level sensor or motor overload pin, converts the working level status into a basic lighting mode instruction code representing a specific fault type, and sends it to the communication transceiver module. The communication transceiver module encapsulates the basic lighting mode instruction code into a serial data frame and sends it to the light effect calculation module on the display panel via the UART data bus. The high-frequency electromagnetic interference radiated by the high-power brushless motor during high-speed operation is successfully isolated through the purely digital UART communication link, solving the technical pain point that traditional analog level signals are prone to waveform distortion in complex electromagnetic environments. The light effect calculation module, as an independent algorithm processing model unit, receives serial data frames and performs protocol parsing to obtain basic lighting mode instruction codes. Based on the basic lighting mode instruction codes, it extracts dynamic light effect parameters covering parameters such as the frequency of rapid warnings, the duration of infinite loops, the rate of sharp transitions, and the sequence of alternating red and yellow colors. The light effect calculation module inputs the extracted dynamic light effect parameters into the internal interpolation generation unit for logical operations, generating a preset light effect digital stream representing the breathing flashing warning effect as the model output. The preset light effect digital stream is then sent to the data cache unit for storage. This removes the computationally intensive lighting effect rendering task from the main power control board, completely solving the problem of excessive load on the main control chip's computing resources. Subsequently, the array drive module reads the preset light effect digital stream stored in the data buffer unit, converts the preset light effect digital stream into a single-line return-to-zero code digital electrical signal and sends it to the series-type light-emitting diode array; the series-type light-emitting diode array receives the single-line return-to-zero code digital electrical signal, extracts the cascaded data frames in the single-line return-to-zero code digital electrical signal, and adjusts the output current amplitude of the built-in transistor of the light-emitting diode according to the high and low level pulses in the cascaded data frames, so as to precisely control the output of the front panel to display a high-brightness fault warning light effect of alternating red and yellow, intuitively guiding the user to troubleshoot mechanical faults of the floor scrubber.
