The main disadvantage of this method is that in order to accurately collect PD voltage data, the position of the potentiometer must be very close to the PD position, and the distance between the person and the working laser is very close. The laser is in a working state. If the laser works abnormally, it will cause a major personal safety accident to the debugging personnel. Summary of the invention

[0003] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a PD debugging system and its application method, which compares the PD data value collected by the main control module with the actual output power PD data value of the laser module through the host computer module, and adjusts the PD display value of the main control module and the reflected light PD display value through the host computer module, so that the final displayed PD data value is consistent with the actual output power PD data value of the laser module, so that the debugging personnel can complete the PD data value debugging safely, reliably and without risk at a long distance, greatly reducing the safety risk of the debugging personnel.

[0032] Furthermore, the host computer module 5 also includes a current signal module; the current signal module is electrically connected to the main control module 4 .

[0033] Furthermore, the host computer module 5 also includes a temperature signal module, and the temperature signal module is electrically connected to the main control module 4 .

[0034] Furthermore, the host computer module 5 also includes a humidity signal module, and the humidity signal module is electrically connected to the main control module 4 .

[0035] Furthermore, the host computer module 5 also includes a pump source quantity signal module, and the pump source quantity signal module is electrically connected to the main control module 4 .

[0036] Furthermore, the host computer module 5 includes a PD display module and a PD setting module.

[0037] An application method of a PD debugging system comprises the following steps:

[0038] Step S1, when the laser module 1 works normally to generate the optical signal of the main power PD and the optical signal of the reflected light PD, the power meter module 2 reads the actual value D1 of the data of the main power PD through the power meter;

[0039] Step S2, the PD feedback module 3 collects the optical signal of the main power PD and the optical signal of the reflected light PD of the laser module 1 and converts them into the electrical signal of the main power PD and the electrical signal of the reflected light PD and transmits them to the main control module 4; the main control module 4 amplifies the electrical signal of the main power PD and the electrical signal of the reflected light PD collected by the PD feedback module 3 and sends them to the host computer module 5, and the host computer module 5 performs calculation processing on the electrical signal of the main power PD and the electrical signal of the reflected light PD collected by the main control module 4 and displays the corresponding PD data value D2;

[0040] In step S3, the debugging personnel compare the displayed PD data value D2 with the actual value D1 of the data read by the power meter module 2. If the PD data value D2 and the actual value D1 are consistent, the debugging is completed; if the PD data value D2 and the actual value D1 are inconsistent, the host computer module 5 sends a change instruction to the main control module 4, the main control module 4 and the DP feedback module exchange data with each other, and the main control module 4 sends the changed PD data value D2 to the host computer module 5 until the PD data value D2 displayed by the host computer module 5 is consistent with the actual value D1 read by the power meter module 2, and the debugging is completed.

[0041] In step S3, the data exchange between the main control module 4 and the PD feedback module 3 includes the main control module 4 sending the change instruction sent by the host computer module 5 to the PD feedback module 3, and the PD feedback module 3 feedbacks the corresponding signal to the main control module 4 after receiving the change instruction. The PD feedback module 3 has the function of changing the received change instruction into a corresponding electrical signal and feeding it back to the main control module 4, and the main control module 4 then sends the corresponding electrical signal to the host computer module 5 for display, that is, the main control module 4 sends the changed PD data value D2 to the host computer module 5.

[0042] In this embodiment, the host computer module 5 includes a PD display module and a PD setting module. The PD display module includes a main power PD data value display unit and a reflected light PD data value display unit. When the laser of the entire system starts working, the PD feedback module 3 sends the main power PD data value and reflected light PD data value of the laser to the main control module 4. After processing, the main control module 4 sends the data to the PD display module of the host computer module 5, which displays the main power PD data value and the reflected light PD data value in real time respectively.

[0043] The PD setting module includes the main power PD data value setting and the reflected light PD data value setting. When the debugging personnel compare the main power PD data value and the reflected light PD data value in the PD display module with the actual value (the main power PD data value and the reflected light PD data value actually generated by the normal operation of the laser module 1), if they are inconsistent, the main power PD data value or the reflected light PD data value is changed until the main power PD data value D2 of the PD display module is consistent with the actual value D1 of the main power PD data.

[0044] The current signal module, temperature signal module, humidity signal module, and pump source quantity signal module all transmit the internal signal of the laser to the host computer module 5 via the main control module 4 for display, and can display current data, temperature data, humidity data, and pump source quantity data respectively. The PD display module of the host computer module 5 displays the above data in real time.

[0045] like Figure 2 FIG. 1 is a partial block diagram of the PD setting module of the upper computer module 5 of the embodiment. The block diagram includes a PD setting module, a PD display module, and other data display modules.

[0046] The actual data value D1 is the main power PD data value actually generated by the power meter module 2 reading the laser module 1 through the power meter when it works normally. Specifically, the PD data value D2 is the main power PD data value displayed by the host computer module 5. The main power PD data value D2 of the PD display module is adjusted to be consistent with the actual data value D1 of the main power PD. Specifically, the main power PD data value or / and the reflected light PD data value are changed by the PD feedback module 3, and after feedback, the main power PD data value D2 displayed by the host computer module 5 at the final end is consistent with the actual data value D1 of the main power PD.
