[0053] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0054] Fractional laser therapy is a medical device that can irradiate, cut and ablate skin tissue by dividing the laser beam into spots and applying the spots to the surface and deep layers of the skin in the form of a matrix. Fractional laser therapy uses a laser to emit high-energy lasers, so that the lasers with a fixed wavelength can break up the pigments in the diseased tissue in a short time, thereby improving skin problems without damaging the normal tissues around the lesions.

[0055] In some embodiments, the control system of the fractional laser therapy machine is composed of a control layer and a display layer with a touch function. The control layer and the display layer communicate through a serial port, the display layer sends the touch point coordinates to the control layer, and the control layer sends a display instruction to the display layer to control the display layer to display preset text and pictures. The control layer receives the touch point coordinates through the built-in human-computer interaction module, and calls the galvanometer control module to control the working state of the galvanometer and the laser machine, thereby realizing the fractional laser scanning function.

[0056] Because in the above control system, the display layer displays preset text and pictures to the user only after receiving the display instructions sent by the control layer, and the main control unit of the control system is in the control layer, the human-computer interaction performance of the above control system is limited by the controllable ability of the display layer, resulting in low controllability of the fractional laser therapy machine and poor human-computer interaction experience.

[0057] In some embodiments, a display system with a non-real-time multitasking operating system is used as the display layer of the fractional laser therapy machine, such as a tablet computer with an Android system installed, and the human-computer interaction module is moved to the display layer, so that the display layer can have a main control function.

[0058] like Figure 1 As shown, the display layer obtains user instructions according to the menu interface, and sends specific scanning tasks and process scheduling instructions to the control layer with the galvanometer control module, so that the control layer controls the galvanometer and the laser, thereby realizing the dot matrix laser scanning function.

[0059] In order to improve the controllability of the display layer over the control layer in the fractional laser therapy machine of the display layer, some embodiments of the present application provide a command execution method based on the fractional laser therapy machine, such as Figure 2 As shown, the instruction execution method based on the fractional laser therapy machine provided in the present application includes the following steps.

[0060] Step S100: obtaining a user instruction input by the user on the display layer.

[0061] In some embodiments, the display layer is installed with fractional laser therapy machine control software, and the display layer can receive the parameters input by the user through the fractional laser therapy machine control software, and encapsulate the parameters input by the user to generate user instructions. User instructions include first-class instructions, second-class instructions, and third-class instructions. Among them, the first-class instructions are used to read or write parameters to registers, the second-class instructions are used to call task execution submodules, and the third-class instructions are used to indicate the start or end of a task flow.

[0062] Exemplarily, the first type of instruction is a register read and write instruction, which is used to read the parameters in the register or write the parameters input by the user into the register. The second type of instruction is a task scheduling instruction, which is used to control the task scheduling submodule so that the task scheduling submodule sends a control signal to the laser and / or the galvanometer scanner. The third type of instruction is a process instruction, which is used to instruct the task execution submodule to start or end the execution of the task call control instruction.

[0063] Step S200: parse the user instruction to obtain an instruction identifier and instruction parameters.

[0064] In some embodiments, the display layer is used to parse the user instruction to obtain the instruction identifier and instruction parameters in the user instruction. The instruction identifier is used to indicate that the user needs to call a certain execution module to implement a certain function of the fractional laser therapy machine, and the instruction parameter is used to indicate the parameter passed by the user to a certain execution module. The instruction parameter can be one or more, for example, the instruction parameter can be the data that needs to be read.

[0065] Step S300: Obtain an execution module according to an instruction identifier.

[0066] In some embodiments, the instruction identifier is associated with the execution module, that is, one instruction identifier corresponds to one execution module. Exemplarily, the execution module corresponding to the instruction identifier can be obtained by querying the instruction identifier information table. The execution module is set in the control layer, and the control layer sends a control signal to the laser or galvanometer scanner by calling the execution module.

[0067] Step S400: Generate a control instruction according to the instruction identifier and instruction parameters, and send the control instruction to the control layer, so that the execution module executes the control instruction and returns the execution result.

[0068] In some embodiments, the control instruction is used to instruct the control layer to control the laser or galvanometer scanner to perform a corresponding operation, and the instruction identifier and instruction parameters are necessary components of the control instruction. In addition, the control instruction may also include one or more of a frame header, a data length, and a frame tail. Among them, the frame tail may be composed of a verification algorithm, for example, a CRC verification algorithm.

[0069] In the case where the user instruction is a first-class instruction, the control instruction is a register read-write instruction, which is used to call the register submodule to perform the register read-write task. Among them, the control instruction includes the address of the pre-read or written register, and the pre-written data. The control layer can read and write a single register based on the register read-write instruction, or read and write multiple groups of registers at the same time. Table 1 is a data format table of a register read-write instruction provided in this application.

[0070] Table 1 Data format table of register read and write instructions

[0071]

[0072]

[0073] As shown in Table 1, the data format of register read and write instructions may include a frame header, data length, instruction identifier, data segment, and frame tail. The instruction identifier and data segment are necessary parameters. The function description corresponds to the instruction identifier, and the instruction identifier is used to identify the instruction type. Register read and write instructions include register write operation instructions and register read operation instructions.

[0074] When the control layer executes a register write operation instruction, the register write module is called; the frame header of the register write operation instruction is 0x5AA5; the instruction identifier is 0x01; the data segment consists of padding data, at least one register address, and the data to be written to the register address. The padding data is used to characterize the data before the control parameter. For example, the 6th Byte position and the 7th Byte position of the instruction are the register 1 address, and the 8th Byte position and the 9th Byte position are the data to be written to the register. The frame tail is generated using the CRC check algorithm. The data length is related to the number of write registers. For example, the register write operation instruction includes the addresses of registers 1 to register n, the number of registers is n, and the effective data length from the instruction identifier to the frame tail is 3+4*n.

[0075] Exemplarily, when the control layer executes a register read operation instruction, a register read operation is called; the register read operation instruction frame header is 0x5AA5; the instruction identifier is 0x02; the data segment consists of padding data, at least one register address and the data to be read at the register address; the frame tail is generated using a CRC checksum algorithm; the data length is related to the number of registers read.

[0076] It should be understood that the register submodule is used to store the control parameters of the fractional laser therapy machine, and the parameter types include but are not limited to: communication parameters, system parameters, scanning galvanometer parameters, laser parameters, size calibration parameters, scanning control parameters, and custom curve parameters, etc. The register submodule may include at least one register, and different types of parameters may be stored in different register submodules.

[0077] Among them, communication parameters include serial port communication rate, verification function, communication timeout and other parameters. System parameters include whether the peripherals (buzzer, indicator light) follow the laser output, scanner out-of-position alarm, over-pulse, laser attenuation compensation, system status indication, indicator light brightness adjustment and other parameters. Scanning galvanometer parameters include scanner type, scanner amplitude and zero position calibration coefficient, in-place judgment threshold and other parameters. Laser parameters include laser type setting, laser debugging frequency, over-pulse modulation frequency and width and other parameters. Size calibration parameters include amplitude calibration coefficient of laser and indicator light, geometric distortion calibration coefficient, mirror and other parameters. Scanning control parameters include dot matrix light on, light off delay, continuous scan jump delay, continuous scan start delay, continuous scan end delay and other parameters. Custom curve parameters include custom contour vertex data.

[0078] In some embodiments, the register read / write instruction includes a communication class parameter and a register address corresponding to the communication class parameter. The control layer obtains the register read / write instruction and, based on the register address corresponding to the communication class parameter, calls the register submodule to read or write the communication class parameter. Table 2 is a schematic table of register-communication class parameters provided in this application.

[0079] Table 2 Schematic table of register-communication parameters

[0080]

[0081]

[0082] As shown in Table 2, the communication parameters stored in the register submodule include communication rate, communication timeout, and serial port module initialization. The "Data Definition" in Table 2 is an explanation of the communication parameters, for example, UartConfig represents the communication rate, ComOverTime represents the communication timeout, and UartInitialize represents the serial port module initialization. "Address" is used to indicate the corresponding address of the parameters in the same row in the register submodule. Non-volatile is used to indicate the volatility of the parameter, "√" is used to indicate that the parameter is non-volatile, and "×" is used to indicate that the parameter is volatile. "Read and Write" is used to indicate the readable and writable nature of the parameter. "Preset value" is used to indicate the preset parameter value of the parameter.

[0083] According to Table 2, the corresponding address of the communication rate in the register submodule is 0x0010. The communication rate is non-volatile data, which supports relevant personnel to read and write through the motion control layer. Bit0~Bit2 is the serial port speed. The value of Bit0~Bit2 can be any of 000, 001, 010, ..., 111. When the value of Bit0~Bit2 is 000, it means that the serial port speed is 9600bps. Bit3 is the stop bit. The value of Bit3 can be 0 or 1. When the value of Bit3 is 0, it means that the stop bit is 1; when the value of Bit3 is 1, it means that the stop bit is 2. Bit4~Bit5 is the parity bit. The value of Bit4~Bit5 can be 0, 1, 2 or 3. When the value of Bit4~Bit5 is 0 or 3, it means no parity; when the value of Bit4~Bit5 is 1, it means odd parity is used; when the value of Bit4~Bit5 is 2, it means even parity is used.

[0084] The corresponding address of communication timeout in the register submodule is 0x0011, which is non-volatile data and supports relevant personnel to read and write through the motion control layer. The value of communication timeout setting is in the range of [1,10000], and the unit is 0.1ms. For example, the communication timeout value is 5, which means that the relevant data is not counted as communication timeout if it is communicated within 0.5ms, and it is counted as timeout if the relevant data is not received after 0.5ms. The corresponding address of serial port module initialization in the register submodule is 0x0012, which is volatile data and supports relevant personnel to write through the motion control layer. When the serial port module initialization value is written to 1, it means that the communication module is initialized.

[0085] In some embodiments, the register read and write instructions include scanning galvanometer parameters and register addresses corresponding to the scanning galvanometer parameters. The control layer obtains the register read and write instructions, and based on the register address corresponding to the scanning galvanometer parameters, calls the register submodule to read or write the scanning galvanometer parameters. Among them, the scanning galvanometer parameters are used to set parameters such as the type of scanning driver used by the fractional laser therapy machine.

The laser types include sealed glass CO2 lasers and radio frequency CO2 lasers. When the preset value is 0, it means that the sealed glass CO2 laser needs to be called; when the preset value is 1, it means that the radio frequency CO2 laser needs to be called.

The control layer obtains the register read / write instruction and, based on the register address corresponding to the system parameter, calls the register submodule to read or write the system parameter.

[0191] For example, the laser is a sealed glass CO2 laser, and the laser pulse waveform of the laser in the pulse group mode is as follows: Fig.14 As shown, the control layer automatically controls the output of the laser according to the laser pulse power, super pulse time, group pulse high level time, group pulse low level time, pulse group interval, pulse group, timing start time, and group pulse number within the set timing start time, and automatically controls the laser to turn off after the timing start time ends.

[0192] In some embodiments, the user instruction is a third type of instruction, and the third type of instruction is a process instruction, which is used to control the task state of the execution module. The process instruction includes a start execution instruction and an end execution instruction, which are used to instruct the execution module to start executing the received control instruction, or to end the execution of the received control instruction. Table 19 is a data format table of a process instruction provided in this application.

[0193] Table 19 Data format of process instructions

[0194]

[0195] Exemplarily, after receiving the dot scan instruction, the dot scan task scheduling submodule waits for the execution of the dot fill task. In response to the dot scan task scheduling submodule receiving the start execution instruction, the dot fill task starts to be executed.

[0196] Exemplarily, when the continuous laser pulse task scheduling submodule receives an end execution instruction during the process of sending the continuous laser control signal, the continuous laser pulse task scheduling submodule sends an end signal to the laser to stop the laser from emitting laser light.

[0197] Step S500: Generate a reply instruction based on the execution result, and return the reply instruction to the display layer.

[0198] In some embodiments, the execution module executes the control instruction and returns the execution result. A reply instruction is generated according to the execution result, and the reply instruction is returned to the display layer. Exemplarily, the user instruction is used to instruct the calculation of the dot matrix filling point number and the scanning length, and the control layer calls the dot matrix scanning task scheduling submodule and returns the reply instruction. Table 19 is a data format table of a reply instruction provided in this application.

[0199] Table 19 Data format of reply command

[0200]

[0201] As shown in Table 19, the data format of the reply command includes a frame header, data length, command identifier, data segment, and frame tail. The frame header is 0x5AA5; the data length is 0x000B, and the command identifier is 0x83. The data segment consists of data segment padding data, frame tail padding data, and function description segment data. The output data sets multiple layers, and the function description segment data includes the total number of dot matrix scan points in layer 1, the continuous scan length of layer 1, the total number of dot matrix scan points in layer 2, and the continuous scan length of layer 2. The frame tail is 0x3CC3.

[0202] It should be understood that when the task call control instruction calls different execution modules, the execution modules return different results, so the parameters of the data segment in the generated reply instruction are different. This application will not repeat the reply instructions generated by other execution modules.

[0203] By sending reply instructions to the display layer, the operator can obtain the execution data of the fractional laser therapy machine in a timely manner, thereby realizing the normal operation of the fractional laser therapy machine and monitoring the output parameters during the operation, thereby improving the safety and controllability of the fractional laser therapy machine.
