[0078] Please continue to see Fig. 9 and Fig.10 In one embodiment, the laser control component 150 further includes a first voltage follower 153. The input end of the first voltage follower 153 is connected to the output end of the first amplifier 101, and the output end of the first voltage follower 153 is connected to the single-chip microcomputer chip 110. The first voltage follower 153 is used to obtain a first voltage follower signal according to the first amplified signal, and input the first voltage follower signal to the single-chip microcomputer chip 110. The single-chip microcomputer chip 110 is used to adjust the digital potentiometer 151 when the first voltage follower signal is abnormal. The first voltage follower 153 is a type of electronic component that realizes the output voltage changes with the input voltage. That is, the first voltage follower signal obtained by the first voltage follower 153 changes with the change of the first amplified signal. The single-chip microcomputer chip 110 can determine whether the first voltage follower signal is abnormal through the obtained first voltage follower signal, that is, whether the first amplified signal is abnormal and whether the control voltage signal is abnormal. That is to say, the single-chip microcomputer chip 110 can determine whether there is an abnormality in the control voltage signal output by the digital potentiometer 151 through the first voltage follower signal. If there is an abnormality, the single-chip microcomputer chip 110 can adjust the digital potentiometer 151 to re-output a normal control voltage signal.

[0079] In this embodiment, the single-chip microcomputer chip 110 adjusts the digital potentiometer 151 when the first voltage follower signal is abnormal, which can ensure that the first amplified signal obtained is more accurate, thereby ensuring that the final adjustment signal is more accurate; and the first voltage follower 153 can isolate the first amplifier 101 and the single-chip microcomputer chip 110, so that the first amplifier 101 and the single-chip microcomputer chip 110 do not affect each other, which can improve the practicality and reliability of the laser control component 150.

The relay 155 is an electronic control device, which has a control system and a controlled system. The monitoring component 154 can determine whether the second amplified signal is abnormal by judging the second amplified signal output by the second amplifier 102, that is, the monitoring component 154 can judge whether the voltage signal of the laser is abnormal. When the monitoring component 154 detects that the second amplified signal is abnormal, it can control the relay 155 to disconnect, thereby interrupting the operation of the laser and avoiding permanent damage to the laser, thereby improving the practicality and reliability of the laser control component 150.

[0082] In a specific embodiment, the monitoring component 154 may include a preset voltage signal threshold, and the monitoring component 154 determines whether the second amplified signal is abnormal by comparing the second amplified signal with the preset voltage signal.

The voltage regulator is a device that automatically maintains a constant voltage. The voltage regulator provides a voltage stabilization signal to the comparator 105 through the second input terminal of the comparator 105. The comparator 105 compares the received second voltage follower signal and the voltage stabilization signal, and outputs a level signal, through which the relay 155 can be controlled to disconnect to interrupt the working state of the laser. Among them, the level signal can be a high level or a low level, and this embodiment does not impose any restrictions on this. The user can set it according to the types of the comparator 105 and the relay 155.

The single-chip microcomputer chip 110 can display corresponding information on the touch screen 220 according to the level signal. The resistor R57 is used for voltage pull-up and the resistor R56 is used for voltage pull-down.
