Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See attached Figures 1 to 2 As shown, in this embodiment, an integrated control system for a galvanometer laser light includes an integrated control drive device, a power supply 100 and components, wherein the integrated control drive device includes a galvanometer control module 320 and a laser control module 330 integrated on the same drive board 200. In this embodiment, a 24V power supply 100 is used, and the power supply 100 is connected to the integrated control drive device, so that the power supply 100 is used to uniformly supply power to the integrated control drive device and various components connected to the integrated control drive device.

[0017] In this embodiment, the components include a signal input terminal board 430, a galvanometer motor 410 and a laser 420, wherein the galvanometer motor 410 and the laser 420 are electrically connected to the galvanometer control module 320 and the laser control module 330, respectively. Specifically, the galvanometer motor 410 and the laser 420 are connected to the drive board 200 through the connection ports preset thereon, and the connection ports are connected to the galvanometer control module 320 and the laser control module 330 through a predetermined connection circuit, thereby realizing the connection and communication between the galvanometer control module 320 and the laser control module 330 and the galvanometer motor 410 and the laser 420, respectively. The galvanometer control module 320 is used to control the motion state of the galvanometer motor 410; the laser control module 330 is used to control the laser state of the laser 420, thereby, the integrated control driving device performs at least one of the actions of the galvanometer control module 320 controlling the galvanometer motor 410 and the laser control module 330 controlling the laser 420 based on the control instructions of the external signal source.

[0018] Specifically, the signal input terminal board 430 is connected to a connection port preset on the driving board 200 of the integrated control driving device through a signal bus. The signal input terminal board 430 is provided with an ILDA standard interface for connecting an external signal source, so that the control command of the external signal source is transferred to the integrated control driving device through the signal input terminal board 430, and then only the galvanometer control module 320 controls the movement of the galvanometer motor 410, or only the laser control module 330 controls the movement of the laser 420, or not only the galvanometer control module 320 controls the movement of the galvanometer motor 410, but also the laser control module 330 controls the movement of the laser 420.

[0019] See also Figure 1 As shown, in this embodiment, the galvanometer control module 320 includes a galvanometer motion drive module 322 and a galvanometer signal processing module 321, wherein the galvanometer motion drive module 322 is connected to the galvanometer signal processing module 321, wherein the galvanometer signal processing module 321 is used to receive control instructions and convert them into corresponding galvanometer instructions and transmit them to the galvanometer motion drive module 322, and the galvanometer signal processing module 321 receives control instructions from an external signal source through a connection port. The galvanometer motion drive module 322 is connected to the galvanometer motor 410 and is used to control the motion state of the galvanometer motor 410. Specifically, the galvanometer motion drive module 322 controls the X-axis motor and the Y-axis motor of the galvanometer motor 410 based on the galvanometer instructions, thereby adjusting the motion state of the galvanometer motor 410.

[0020] See also Figure 1As shown, in this embodiment, the laser control module 330 includes a laser power driving module 332 and a laser signal processing module 331, wherein the laser power driving module 332 is connected to the laser signal processing module 331, wherein the laser signal processing module 331 is used to receive control instructions and convert them into corresponding laser instructions and transmit them to the laser power driving module 332, and the laser signal processing module 331 receives control instructions from an external signal source through a connection port. The laser power driving module 332 is connected to the laser 420 and is used to control the laser state of the laser 420. Specifically, the laser power driving module 332 controls the switching action and output power of the laser 420 based on the laser instructions, thereby adjusting the laser state of the laser 420.

[0021] The existing galvanometer motion drive module 322 is unable to obtain the working condition information of the galvanometer motor 410 in real time, and the laser power drive module 332 is unable to obtain the working condition information of the laser 420 in real time. The galvanometer motor 410 is overloaded and burned due to the galvanometer motion drive module 322 not timely and effectively controlling the action, or the laser power drive module 332 is not timely and effectively controlling the action, which causes the laser 420 to be overloaded and burned. For this reason, the integrated control drive device of this embodiment also includes a microprocessor control module 350, and the acquisition end of the microprocessor control module 350 is respectively connected to the galvanometer motor 410 and the laser 420. Specifically, the acquisition end of the microprocessor control module 350 is connected to the preset connection port on the drive board through the connection circuit for the galvanometer motor 410 and the laser 420. The control end of the microprocessor control module 350 is electrically connected to the galvanometer control module 320 and the laser control module 330 through the connecting circuit on the driving board, and monitors and judges the working condition information of the galvanometer motor 410 and the laser 420, so that when any abnormality occurs in either the galvanometer motor 410 or the laser 420, the microprocessor control module 350 simultaneously sends corresponding protection instructions to the galvanometer control module 320 and the laser control module 330, so that both the galvanometer motor 410 and the laser 420 are switched to the appropriate state.

[0022] Specifically, for the galvanometer motor 410, the microprocessor control module 350 can monitor and collect parameters such as the output current, operating temperature, and reflector position information of the galvanometer motor 410, thereby determining the current range, temperature range, and position range that meet the requirements through weighted algorithms, position comparison, and other methods, and make real-time judgments and discover abnormalities of the galvanometer motor 410 in real time. For the laser 420, the microprocessor control module 350 can determine the temperature range, power range, and other requirements of the laser parameters through weighted algorithms, and other methods through the operating temperature, output power, and other parameters of the laser 420, and make real-time judgments and discover abnormalities of the laser 420 in real time. Once any abnormality occurs in the galvanometer motor 410 and the laser 420, the protection mechanism is triggered, and the microprocessor control module 350 simultaneously sends corresponding protection instructions to the galvanometer control module 320 and the laser control module 330, so that the galvanometer motor 410 and the laser 420 are switched to appropriate states.

[0023] To facilitate the understanding of the above-mentioned microprocessor control module 350, further explanation is given below in conjunction with specific embodiments. If the galvanometer motor 410 has an abnormal situation of over-temperature or over-current during operation, the microprocessor control module 350 sends a protection instruction to the galvanometer control module 320 and the laser control module 330, so that the galvanometer motion drive module 322 controls the galvanometer motor 410 to gradually reduce the output power of 50%, 30%, 1%, etc., and the laser power drive module 332 controls the laser 420 to gradually reduce the output power of 50%, 30%, 1%, etc., so that the galvanometer motor 410 and the laser 420 gradually return to a normal state. If the galvanometer motor 410 has an abnormal situation of excessive position of the reflector during operation, the galvanometer motion drive module 322 can control the galvanometer motor 410 to reset, and the laser power drive module 332 can control the laser 420 to turn off, so that the galvanometer motor 410 and the laser 420 gradually return to their initial state. If the laser 420 has abnormal conditions such as over-temperature or overload during operation, the laser power driving module 332 can control the laser 420 to gradually reduce the output power of 50%, 30%, 1%, etc. or turn off the laser 420, and the galvanometer motion driving module 322 controls the galvanometer motor 410 to reset, so that the galvanometer motor 410 and the laser 420 gradually return to the initial state. During actual operation, the trigger protection mechanism can be set as needed to control the galvanometer motor 410 and the laser 420 according to the product's own situation or operation requirements, so as to ensure that the galvanometer motor 410 and the laser 420 can be switched to the appropriate state, play a protective role, and effectively extend the service life of the system.

[0024] In this embodiment, the integrated control drive device also includes a heat dissipation control module 340, and the components also include a heat dissipation fan 440 and an auxiliary heating wire 450 connected to the heat dissipation control module 340. At this time, the control end of the heat dissipation module is connected to the heat dissipation fan 440 and the auxiliary heating wire 450 respectively. The collection end of the heat dissipation control module 340 can monitor the internal temperature of the collection machine in real time with the help of a preset temperature probe, so as to judge in real time whether the temperature inside the machine is too high or too low, and thus control the heat dissipation fan 440 or the heating unit accordingly. Specifically, if the temperature inside the machine is too high and the heat dissipation effect needs to be enhanced, the heat dissipation control module 340 controls the heat dissipation fan 440 to start or increase the speed, so as to discharge the temperature inside the machine in time; on the contrary, if the temperature inside the machine is too low, the heat dissipation control module 340 controls the auxiliary heating wire 450 to play the role of auxiliary heating, so that the inside of the machine is kept at a normal working temperature, which is suitable for the low temperature working environment in winter.

[0025] Since there are some differences in the working voltages required by the integrated control drive device and each component, the integrated control drive device also includes a power conversion module 310 integrated on the same drive board 200, wherein the power conversion module 310 is connected to the power supply 100 via a 24V input port, and is provided with a plurality of output ports with different voltage values ​​for corresponding connection of each module or each component, which is not specifically limited here and can be set and connected according to actual needs.

[0026] The galvanometer control module 320, laser control module 330, heat dissipation control module 340 and power conversion module 310 of the integrated control drive device are integrated on the same drive board 200. The connection circuits between the modules on the same drive board 200 can be set on the drive board 200 without additional wiring and wiring. Secondly, each template is connected to each component through the preset connection port on the drive board 200, which can realize the standardization of wiring and facilitate assembly operations. A single power supply 100 is used to power each module and each component, thereby greatly reducing the volume of the integrated control system, optimizing and improving the internal layout space to make the internal structure more compact, the overall submission is smaller, and the transportation cost is low. At the same time, the use of an integrated structure can facilitate production wiring and data acquisition monitoring.

[0027] Furthermore, the above-mentioned connection circuit can be formed on the driving board 200 by etching. Its structure and original circuit composition belong to common knowledge and will not be elaborated here.

[0028] The signal transmission circuits such as communication and transmission between the above-mentioned modules and components, as well as the data interaction such as monitoring, judgment, control, and instructions of each module, all belong to the category of computer programs, involving computer processors and software programs, which are not elaborated or specifically limited here, and their structural principles are conventional technical means for those skilled in the art. Secondly, the processors involved in the above-mentioned modules can utilize any of various other technologies, including special-purpose computers, computer systems (including, for example, microcomputers, minicomputers or mainframes, programmed microprocessors, microcontrollers), peripheral integrated circuit components, CSIC (customer-specific integrated circuits) or ASICs (application-specific integrated circuits) or other integrated circuits, logic circuits, digital signal processors, programmable logic devices (such as FPGAs, PLDs, PLAs or PALs), or any other devices or device arrangements that can implement the steps of the process of the present invention.
