[0038] Reference Figure 1The embodiment of the present application discloses a test system for a thyristor pulse trigger module, including: a standard AC source module 3, used to generate three-phase Ua / Ub / Uc voltage information; a pulse trigger module 2 to be tested, connected to the standard AC source module 3, used to receive three-phase Ua / Ub / Uc voltage information, and generate pulse information; a main control module 1, connected to the standard AC source module 3 and the pulse trigger module 2 to be tested, used to generate a pulse trigger instruction, and based on the three-phase voltage information and the pulse information, generate a pulse information number test result and a trigger angle test result, and generate a pulse trigger instruction; a power supply module 4, connected to the main control module 1, used to provide power to the main control module 1; a display module 5, connected to the main control module 1, used to receive and display the pulse information number test result and the trigger angle test result; the display module 5 is connected to the power supply module 4, used to provide power to the display module 5.
[0039] In some embodiments, the power supply module 4 is respectively connected to the main control module 1 and the display module 4 to provide power to the main control module 1 and the display module 5 so that the main control module 1 and the display module 5 can work normally; the main control module 1 generates a pulse trigger instruction, and the first communication interface of the main control module 1 sends the pulse trigger instruction to the pulse trigger module 2 to be tested, and the pulse trigger module 2 to be tested responds to the pulse trigger instruction and generates pulse information. Subsequently, the pulse trigger module 2 to be tested sends the pulse information to the main control module 1 through the level signal interface, wherein the first communication interface is an optical fiber interface, and information can be sent and received through the optical fiber interface, and the level signal interface is an electrical signal.
[0040] The standard AC source module 3 is connected to the main control module 1 and the pulse trigger module 2 to be tested, respectively. The standard AC source module 3 generates three-phase Ua / Ub / Uc voltage information and sends the three-phase Ua / Ub / Uc voltage information to the main control module 1 and the pulse trigger module 2 to be tested. The main control module 1 monitors the received three-phase Ua / Ub / Uc voltage information, that is, the main control module 1 calibrates the voltage phase starting point of the received three-phase Ua / Ub / Uc voltage information, and the pulse trigger module 2 to be tested uses the received three-phase Ua / Ub / Uc voltage information as the basic AC source for generating pulse information, so that the pulse trigger module 2 to be tested can generate pulse information.
[0041] When the main control module 1 realizes the calibration of the phase starting point of the three-phase Ua / Ub / Uc voltage information, it starts to monitor the received pulse information and start to record the number of pulse information, and calculates the trigger angle based on the number of recorded pulse information. Subsequently, when the number of pulse information and the trigger angle meet the test requirements, the main control module 1 sends the test results including the number of pulse information and the trigger angle to the display module through the second communication interface for display, so that the main control module 1 can accurately complete the statistics of the number of pulse information and the determination of the trigger angle, reduce the errors caused by human factors, and improve the efficiency of determining the number of pulse information and the trigger angle.
[0042] Reference Figure 2 The main control module 1 sends a pulse trigger instruction to the pulse trigger module 2 to be tested. The pulse trigger module 2 to be tested responds to the pulse trigger instruction and generates pulse information. Subsequently, the main control module 1 calculates the number of pulse information and the trigger angle by monitoring the pulse information. Next, the main control module 1 determines whether the number of pulse information and the trigger angle meet the test requirements. When the main control module 1 determines that the number of pulse information and the trigger angle meet the test requirements, the test results including the number of pulse information and the trigger angle that meet the test requirements are sent to the display module through the second communication interface for display, so as to facilitate monitoring by the staff.
[0043] Reference Figure 3 The main control module 1 includes: a zero-crossing detection module 11, a main control unit 12, a test result determination module 6, a first counting module 13 and a second counting module 14; the zero-crossing detection module 11 is connected to the standard AC source module 3, and is used to receive three-phase Ua / Ub / Uc voltage information and generate phase starting point confirmation information; the first counting module 13 is connected to the zero-crossing detection module 11, and is used to receive the phase starting point confirmation information and record the numerical value; the second counting module 14 is connected to the zero-crossing detection module 11, and is used to receive the phase starting point confirmation information and record the numerical value of the number of pulse information; the main control unit 12 is connected to the pulse trigger module 2 to be tested, and is used to receive pulse information, monitor the rising edge of the pulse information and record the number of pulse information.
[0044] The test result determination module 6 is used to receive the numerical values recorded by the first counting module 13 and the second counting module 14, and to generate the pulse information number test result and the trigger angle test result; the test result determination module 6 specifically includes: a trigger angle calculation module 15, used to receive and calculate the count value of the first counting module 13, and to generate the pulse angle test result; a judgment module 16, used to receive and judge the count value of the second counting module 14, and to generate the pulse information number test result.
[0045] In some embodiments, the zero-crossing detection module 11 receives the three-phase Ua / Ub / Uc voltage information generated by the standard AC source module 3, and performs zero-crossing detection on the three-phase Ua / Ub / Uc voltage information to generate phase starting point confirmation information, and then sends the phase starting point confirmation information to the first counting module 13 and the second counting module 14. The first counting module 13 and the second counting module 14 start in response to the phase starting point confirmation information and begin to record numerical values.
[0046] The main control unit 12 receives the pulse information generated by the pulse trigger module 2 to be tested, and captures the rising edge of the pulse information. Whether the main control unit 12 captures the rising edge of the pulse information is used as a condition for whether the count value of the first counting module 13 is increased. When the main control unit 12 captures the rising edge of the pulse information and the count value of the first counting module 13 is less than the maximum value that the first counting module 13 can record, the first counting module 13 sends the count value to the trigger angle calculation module 15 for trigger angle calculation. The calculation formula is: pulse information trigger angle = 360*count value / maximum value; then it is determined whether the calculated pulse information trigger angle is within the limited value range. When the pulse information trigger angle is within the limited value range, it indicates that the test requirements are met and the test is passed. At the same time, the trigger angle calculation module 15 generates a trigger angle test result including the pulse information trigger angle and sends it to the display module 5 through the second communication interface for display; thereby, the main control unit 12, the first counting module 13 and the trigger angle calculation module 15 in the main control module 1 are used to accurately complete the determination of the trigger angle, reduce the occurrence of errors in the trigger angle caused by human factors, and improve efficiency.
[0047] Reference Figure 4 The main control unit 12 in the main control module 1 performs zero-crossing detection on the three-phase Ua / Ub / Uc voltage information. When the three-phase Ua / Ub / Uc voltage information is detected to have crossed zero, the first counting module 13 is started, and the count value N1 of the first counting module 13 is increased by 1; when the count value N1 is greater than or equal to the maximum value, the count value of the first counting module 13 is cleared; when the count value N1 is less than the maximum value and the main control unit 12 does not capture the rising edge of the pulse information, the count value N1 of the first counting module 13 is increased by 1; when the count value N1 is less than the maximum value and the main control unit 12 captures the rising edge of the pulse information, the count value N1 is recorded and sent to the trigger angle calculation module 15 for trigger angle calculation, and then it is determined whether the trigger angle meets the test requirements, and finally the test result including the trigger angle that meets the test requirements is sent to the display module through the second communication interface for display.
[0048] The main control unit 12 receives the pulse information generated by the pulse trigger module 2 to be tested, and captures the rising edge of the pulse information. Whether the main control unit 12 captures the rising edge of the pulse information is used as a condition for whether the excitation count value of the second counting module 14 is increased. When the main control unit 12 does not capture the rising edge of the pulse information, the count value of the second counting module 14 increases by one. Each time the main control unit 12 captures the rising edge of the pulse information, the number of pulse information counted increases by one; when the count value of the second counting module 14 is greater than or equal to the limit value, the main control unit 12 records the current number of pulse information and sends the number of pulse information to the judgment module 16. The judgment module 16 judges whether the number of pulse information is equal to the preset reference value. When the number of pulse information is equal to the preset reference value, it indicates that the pulse number test has passed, and a test result containing the number of pulse information is generated, and the test result is sent to the display module 5 through the second communication interface for display; thereby, the main control chip 12 and the second counting module 14 in the main control module 1 are used to accurately complete the determination of the number of pulse information, reduce the occurrence of errors in the determination of the number of pulse information due to human factors, and improve efficiency.
[0049] Reference Figure 5 The main control unit 12 in the main control module 1 performs zero-crossing detection on the three-phase Ua / Ub / Uc voltage information. When the three-phase Ua / Ub / Uc voltage information is detected to be zero-crossing, the second counting module 14 is started, and the count value N2 of the second counting module 14 is increased by 1; when the main control unit 12 does not capture the rising edge of the pulse information, the count value N2 of the second counting module 14 is increased by 1; when the main control unit 12 captures the rising edge of the pulse information, the number of pulse information counted by the main control unit 12 is increased by 1; when the count value N2 of the second counting module 14 is less than the limit value , the count value N2 of the second counting module 14 is increased by 1, and the main control unit 12 repeatedly detects the number of pulse information; when the count value N2 of the second counting module 14 is greater than or equal to the limit value, the main control unit 3 records the number of pulse information; then the main control unit 3 sends the number of pulse information to the judgment module 16 to judge whether the number of pulse information is equal to the reference value. When the number of pulse information is equal to the reference value, it means that the number of pulse information meets the test requirements, and then the judgment module 16 sends the test result including the number of pulse information to the display module 5 through the second communication interface for display.
