[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] In a first aspect, embodiments of the present application provide a switchable dual-wavelength laser system.

[0039] In one embodiment, referring to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of an embodiment of a switchable dual-wavelength laser system of the present application. Figure 1 As shown, the switchable dual-wavelength laser system includes: a first wavelength laser system, a second wavelength laser system, a first wavelength selection switch, a second wavelength selection switch, a human-computer interaction system, a first wavelength master control circuit, and a second wavelength master control circuit. The first wavelength laser system and the second wavelength laser system are respectively used to generate lasers of corresponding wavelengths, and the first wavelength and the second wavelength are different. The human-computer interaction system is used to establish a connection (communication connection) with the selected wavelength laser system to realize the human-computer interaction function. The first wavelength selection switch corresponds to the first wavelength laser system, and the second wavelength selection switch corresponds to the second wavelength laser system. The two wavelength selection switches are respectively used to select the corresponding wavelength laser systems.

[0040] The first wavelength master control circuit is respectively connected to the first wavelength selection switch, the second wavelength selection switch and the human-computer interaction system. Specifically, the wavelength selection switch is connected to the communication interface of the human-computer interaction system. The first wavelength master control circuit is connected to and controls the first wavelength laser system. The first wavelength master control circuit is also connected to the second wavelength master control circuit through a control signal line and a communication signal line. The second wavelength master control circuit is connected to and controls the operation of the second wavelength laser system, which includes the entire process from startup to shutdown.

[0041] When the first wavelength selection switch is selected, the first wavelength master control circuit connects the human-computer interaction system to the first wavelength laser system; when the second wavelength selection switch is selected, the first wavelength master control circuit connects the human-computer interaction system to the second wavelength master control circuit, and the second wavelength master control circuit operates the second wavelength laser system when connected to the human-computer interaction system.

[0042] In this embodiment, the switching connection between the human-machine interaction system and the two wavelength laser systems is realized through the first wavelength master control circuit, and a master-slave relationship is formed between the first wavelength master control circuit and the second wavelength master control circuit. The switching of the wavelength laser system can be realized only in the first wavelength master control circuit, which solves the problem of using an independent switching control circuit in the related art. The overall system removes the independent switching control circuit, reduces the connection between the functional devices, simplifies the control circuit, saves the overall cost, and improves the anti-interference ability and reliability.

[0043] Furthermore, in one embodiment, the first wavelength master control circuit can realize the switching between the first wavelength laser system and the second wavelength laser system through an internally set switch. When the machine is turned on, the initial state of the switch is that the human-computer interaction system is connected to the first wavelength master control circuit, and the first wavelength master control circuit realizes the display of the boot process interface, the display of related operation prompts, and the display of common detection results through the human-computer interaction system. Then the first wavelength master control circuit cyclically detects the first wavelength selection switch and the second wavelength selection switch.

[0044] If it is detected that the first wavelength selection switch is selected, the first wavelength master control circuit controls the first wavelength laser system to start, that is, it starts to enter the working state, and displays the working interface of the first wavelength laser system and related working parameters, modes, states, etc. through the human-computer interaction system. The first wavelength master control circuit responds to the operation of the working interface, receives signals such as the adjustment and operation instructions of the working parameters, modes, and states, and controls the operation of the first wavelength laser system. At the same time, the first wavelength master control circuit continues to detect the first wavelength selection switch and the second wavelength selection switch in a loop.

[0045] Once it is detected that the second wavelength selection switch is selected, the first wavelength laser system exit program is immediately started, that is, it is shut down, and the first wavelength laser system exit interface information is sent to the human-computer interaction system. At the same time, the first wavelength master control circuit sends the second wavelength selection switch selection signal to the second wavelength master control circuit through the ctrl signal line; after receiving the response signal replied by the second wavelength master control circuit through the ask signal line, the sending communication line T of the human-computer interaction system is switched to the serial sending port BT of the second wavelength master control circuit, and the receiving communication line R of the human-computer interaction system is switched to the serial receiving port BR of the second wavelength master control circuit, and connected to the communication port of the second wavelength master control circuit, completing the switch from the first wavelength laser system to the second wavelength laser system. After that, the master control circuit continues to detect the first wavelength selection switch and the second wavelength selection switch in a loop, and responds to the selection signal of the first wavelength selection switch at any time, and switches back to the first wavelength laser system.

[0046] The second wavelength master circuit detects its ctrl signal line cyclically after power-on. When the selection signal of the second wavelength selection switch is not obtained, the second wavelength laser system is always in a waiting state. Once the selection signal of the second wavelength selection switch is received through the ctrl signal line, the second wavelength master circuit first outputs a response signal to the first wavelength master circuit through its ask signal line, and obtains a connection with the human-computer interaction system through the switch switching of the first wavelength master circuit. Then the second wavelength laser system is controlled to enter the working state, and the working interface of the second wavelength laser system and related working parameters, modes, states, etc. are displayed through the human-computer interaction system. The second wavelength master circuit responds to the operation of the working interface and receives signals such as adjustment and operation instructions of working parameters, modes, and states. At the same time, the first wavelength master circuit cyclically detects the first wavelength selection switch and the second wavelength selection switch. Once it is detected that the first wavelength selection switch is selected, an exit signal is sent to the second wavelength master circuit through the ctrl signal line, and the second wavelength master circuit sends a response signal to the first wavelength master circuit through the ask signal line, starts the exit program of the second wavelength laser system, and sends the interface information of the exit of the second wavelength laser system to the human-computer interaction system.

[0047] In this embodiment, the switching between the first wavelength laser system and the second wavelength laser system is achieved by a switching switch inside the first wavelength master control circuit, without the need for a separate switching control circuit. The system circuit and wiring structure are relatively simple, reducing the cost of the entire system.

[0048] Furthermore, in one embodiment, the dual-wavelength laser system can be arranged in a medical laser device to realize free switching between two laser systems of different wavelengths. Taking the dual-wavelength laser therapy machine used in urological surgery as an example, the wavelength of the first wavelength laser system is 1470nm, and the wavelength of the second wavelength laser system is 2100nm.

[0049] Further, in one embodiment, if Figure 2 , which is a schematic diagram of the switching control of the first wavelength master control circuit. The first wavelength master control circuit includes a first single-chip microcomputer. In order to highlight the key points, the ports of the first single-chip microcomputer used for the control of the first wavelength laser system and the acquisition of digital signals are not shown, and only the pin connections for the switching control are shown, involving seven pins (i.e., pins 24, 25, 33, 34, 42, 43, and 53).

[0050] Specifically, the first pin 25 of the first single-chip microcomputer is connected to the first wavelength (1470nm) selection switch through the seventh socket J5, and the second pin 24 is connected to the second wavelength (2100nm) selection switch through the sixth socket J4. The first single-chip microcomputer determines whether the first wavelength selection switch or the second wavelength selection switch is selected through the level signal. Specifically, when the first wavelength selection switch or the second wavelength selection switch is selected, the corresponding pin becomes the first level.

[0051] In this example, the first pin 25 and the second pin 24 of the first single-chip microcomputer are defined as pull-up input ports, which are respectively used to collect signals of the corresponding wavelength selection switches. When the corresponding wavelength selection switch is not selected, the corresponding pin is at a high level; when a wavelength selection switch is selected, the corresponding pin is short-circuited to the ground and is pulled down to a low level.

[0052] The third pin 33 and the fourth pin 34 of the first single-chip microcomputer serve as the communication signal ports between the second wavelength master circuit, wherein the third pin 33 of the first single-chip microcomputer is connected to the second wavelength master circuit through the ask signal line, and is used to detect the first level response signal sent by the second wavelength master circuit. The fourth pin 34 of the first single-chip microcomputer is connected to the second wavelength master circuit through the ctrl signal line, and when the second wavelength selection switch is selected, the fourth pin 34 of the first single-chip microcomputer outputs the first level selection signal or the second level exit signal to the second single-chip microcomputer of the second wavelength master circuit. In this embodiment, the third pin 33 of the first single-chip microcomputer serves as the pull-up input port, and the fourth pin 34 is defined as the output port, the first level is a low level, and the second level is a high level.

[0053] like Figure 3 The figure shows the switching control schematic diagram of the second wavelength master control circuit. The second wavelength master control circuit includes a second single-chip microcomputer. In order to highlight the key points, the ports of the second single-chip microcomputer used for the control of the second wavelength laser system and the acquisition of digital signals are not shown. Only the pin connections for switching control are shown, involving four pins (i.e., pins 24, 25, 42, and 43).

[0054] like Figure 2 and Figure 3 As shown, the third pin 33 and the fourth pin 34 of the second single-chip microcomputer also serve as communication signal ports with the first wavelength master control circuit. The third pin 33 of the second single-chip microcomputer outputs a first level response signal to the third pin 33 of the first single-chip microcomputer through the ask signal line.

[0055] In this embodiment, the third pin 33 of the second single-chip microcomputer is used as an output port, and the fourth pin 34 of the second single-chip microcomputer is defined as a pull-up input port. The fourth pin 34 of the second single-chip microcomputer is connected to the fourth pin 34 of the first single-chip microcomputer through the ctrl signal line, and is used to receive a first-level selection signal or a second-level exit signal issued by the first single-chip microcomputer, and the first level is a low level and the second level is a high level.

[0056] Further, the first single-chip microcomputer is connected to the second single-chip microcomputer through a socket. Specifically, the first wavelength master control circuit includes a third socket J3, the second wavelength master control circuit includes a fifth socket J32, and the communication signal port of the second wavelength master control circuit is connected to the third socket J3 through the fifth socket J32. Specifically, the third pin 33 of the first single-chip microcomputer is connected to the third socket J3 through the ask signal line, the fourth pin 34 of the first single-chip microcomputer is connected to the third socket J3 through the ctrl signal line, the third pin 33 of the second single-chip microcomputer is connected to the fifth socket J32 through the ask signal line, the fourth pin 34 of the second single chip is connected to the fifth socket J32 through the ctrl signal line, and the fifth socket J32 is connected to the third socket J3.

[0057] like Figure 2 As shown, the first wavelength master control circuit also includes a first socket J1 and a switching relay JD1, and the first socket J1 is connected to the human-computer interaction system and the switching relay JD1 respectively. The fifth pin 42 and the sixth pin 43 of the first single-chip microcomputer serve as the serial interface of the first wavelength laser system, wherein the fifth pin 42 is defined as the serial transmission port AT of the first wavelength master control circuit, and the sixth pin 43 is defined as the serial receiving port AR of the first wavelength master control circuit, and both AT and AR are connected to the switching relay JD1.

[0058] In this embodiment, the fifth pin 42 of the first single-chip microcomputer is connected to the contact 2 of the switching relay JD1, and the sixth pin 43 of the first single-chip microcomputer is connected to the contact 9 of the switching relay JD1. The receiving communication line R of the human-computer interaction system is connected to the contact 8 of the switching relay JD1 through the first socket J1, and the sending communication line T of the human-computer interaction system is connected to the contact 3 of the switching relay JD1 through the first socket J1.

[0059] The first wavelength master control circuit further includes a driver 7407. The seventh pin 53 of the first single chip microcomputer is used as a switching control port AC connected to the driver 7407. The driver 7407 is connected to and controls the switching relay JD1.

[0060] like Figure 2 and Figure 3As shown, the first wavelength master control circuit also includes a second socket J2, the second wavelength master control circuit also includes a fourth socket J22, the fifth pin 42 of the second single-chip microcomputer is defined as a serial transmission port BT of the second wavelength master control circuit, the sixth pin 43 of the second single-chip microcomputer is defined as a serial receiving port BR of the second wavelength master control circuit, BT and BR are both connected to the fourth socket J22, and the fourth socket J22 is connected to the switching relay JD1 through the second socket J2. Specifically, BR is connected to the contact 7 of the switching relay JD1, and BT is connected to the contact 4 of the switching relay JD1.

[0061] When the seventh pin 53 outputs the second level, the driver 7407 controls the switching relay JD1 to be in the released state, at which time the contacts 8 and 9 of the switching relay JD1 are closed, the contacts 3 and 2 are closed, and the fifth pin 42 (AT) and the sixth pin 43 (AR) of the first single-chip microcomputer communicate serially with the human-computer interaction system through the switching relay JD1 and the first socket J1. When the first wavelength selection switch is selected, the first wavelength laser system is connected to the human-computer interaction system through the first single-chip microcomputer and the switching relay JD1.

[0062] When the seventh pin 53 outputs the first level, the driver 7407 controls the switching relay JD1 to be in the energized state, at which time the contacts 8 and 7 of the switching relay JD1 are closed, and the contacts 3 and 4 are closed, and the fifth pin 42 (BT) and the sixth pin 43 (BR) of the second single-chip computer communicate serially with the human-computer interaction system through the switching relay JD1 and the first socket J1. When the second wavelength selection switch is selected, the second wavelength laser system is connected to the human-computer interaction system through the second single-chip computer and the switching relay JD1.

[0063] In the above embodiment, the second level is a high level, and the first level is a low level.

[0064] In a second aspect, the present application also provides a switching method for a switchable dual-wavelength laser system, such as Figure 1 As shown, the method includes:

[0065] When the system is powered on, the first wavelength master control circuit cyclically detects the first wavelength selection switch and the second wavelength selection switch;

[0066] If the first wavelength selection switch is selected, the first wavelength master control circuit controls the first wavelength laser system to establish a connection with the human-computer interaction system through switching, and the first wavelength laser system displays operation information through the human-computer interaction system and receives user operations through the human-computer interaction system.

[0067] If the second wavelength selection switch is selected, the first wavelength master control circuit controls the second wavelength laser system to start through the second wavelength master control circuit, and controls the second wavelength laser system to establish a connection with the human-computer interaction system. The second wavelength laser system displays operation information through the human-computer interaction system and receives user operations through the human-computer interaction system.

[0068] Furthermore, in one embodiment, when the system is powered on, the first wavelength laser system and the human-computer interaction system are connected by default. When the second wavelength selection switch is selected, the first wavelength master control circuit turns off the first wavelength laser system; the first wavelength master control circuit turns on the second wavelength laser system through the second wavelength master control circuit, and connects the second wavelength laser system and the human-computer interaction system.

[0069] Furthermore, in one embodiment, the first wavelength master control circuit senses that the first wavelength selection switch or the second wavelength selection switch is selected. When one wavelength selection switch is selected, it determines whether a wavelength laser system corresponding to another wavelength selection switch is currently running. If so, the first wavelength master control circuit controls the currently running wavelength laser system to shut down and then starts the wavelength laser system corresponding to the selected wavelength selection switch; if not, the wavelength laser system corresponding to the selected wavelength selection switch is controlled to start.

[0070] like Figure 4 As shown, a specific embodiment of a switching method for a switchable dual-wavelength laser system is provided, and this embodiment includes the following steps:

[0071] S1. When the system is powered on, all control ports are in reset state. By default, the first wavelength laser system is connected to the human-computer interaction system. At this time, the switching relay JD1 is in the released state, and the human-computer interaction system is connected to the communication port of the first wavelength main control circuit. The first wavelength main control circuit first controls the display of the whole machine's power-on process interface, the display of related operation prompts, and the display of the detection results of public signals such as cooling water level, water flow, remote control interlock, and foot pedal, and then enters S2.

[0072] S2, the first wavelength master control circuit cyclically detects the first wavelength selection switch and the second wavelength selection switch to determine whether the first wavelength selection switch or the second wavelength selection switch is selected; if it is detected that the first wavelength selection switch is selected, enter S3; if it is detected that the second wavelength selection switch is selected, enter S5.

[0073] S3, the first wavelength main control circuit controls the first wavelength laser system to start working, controls the human-computer interaction system to display through the communication port, and responds to the instructions of the human-computer interaction system; enter S4.

[0074] S4, the first wavelength master control circuit cyclically detects the first wavelength selection switch and the second wavelength selection switch to determine whether the first wavelength selection switch or the second wavelength selection switch is selected; if it is detected that the first wavelength selection switch is selected, repeat step S4; if it is detected that the second wavelength selection switch is selected, enter S5.

[0075] S5, the second wavelength selection switch is selected, the first wavelength laser system exit program is immediately started, and the first wavelength laser system exit interface information is sent to the human-computer interaction system. At the same time, the first wavelength single-chip computer sends a low-level selection signal to the second wavelength single-chip computer through the ctrl signal line, and after receiving the low-level response signal replied by the second wavelength single-chip computer through the ask signal line, the seventh pin 53 outputs a low level as the switching control port AC, the switching relay JD1 is in the absorbing state, the sending communication line T of the human-computer interaction system is switched to the serial sending port BT of the second wavelength main control circuit, and the receiving communication line R of the human-computer interaction system is switched to the serial receiving port BR of the second wavelength main control circuit, completing the switching from the first wavelength laser system to the second wavelength laser system, and entering S6.

[0076] S6. The first wavelength master control circuit cyclically detects the first wavelength selective switch and the second wavelength selective switch to determine whether the first wavelength selective switch or the second wavelength selective switch is selected; if it is detected that the first wavelength selective switch is selected, the process goes to step S7; if it is detected that the second wavelength selective switch is selected, the process repeats step S6.

[0077] S7, the first wavelength selection switch is selected, the first wavelength single-chip microcomputer sends a high-level exit signal to the second wavelength single-chip microcomputer through the ctrl signal line, and after receiving the high-level response signal replied by the second wavelength single-chip microcomputer through the ask signal line, the seventh pin 53 outputs a high level as the switching control port AC, the switching relay JD1 is in the released state, the sending communication line T of the human-computer interaction system is switched to the serial sending port AT of the first wavelength master circuit, and the receiving communication line R of the human-computer interaction system is switched to the serial receiving port AR of the first wavelength master circuit, completing the switching from the second wavelength laser system to the first wavelength laser system, and entering S4.

[0078] In this embodiment, by cyclically detecting which of the first wavelength selection switch and the second wavelength selection switch is selected, free switching of the two wavelength laser systems is achieved, and the detection function and the switching function can be completed by connecting the circuit devices through the pins of the single-chip microcomputer in the first wavelength main control circuit. There is no need to use an independent switching control circuit, which reduces the complexity of the circuit. The above functions can be achieved by the single-chip microcomputer and the switching switch, which reduces the manufacturing cost and improves the reliability of the system.
