[Abstract]:With the development of large laser equipments in China, the performance of pulsed xenon lamp and the output of laser energy are required. The engineering design, implementation and reliable operation of the high power laser device are closely related to the technical specifications and service life of the pulsed xenon lamp. The quality of the pulsed xenon lamp will directly affect the reliability of the operation of the high power laser device. A high power pulsed xenon lamp detection system with practical function, advanced technology and simple operation is developed to detect the early failure and life of the high power pulsed xenon lamp in a certain project. Furthermore, the manufacturing process of xenon lamp is improved to improve its quality and service life. The high power pulsed xenon lamp detection system uses S7-300PLC as the control core, remote centralized control and management through Ethernet, and can automatically complete the charging and discharging process of the xenon lamp detection system and automatically judge the abnormal discharge current waveform. This paper starts with the hardware of the high power pulsed xenon lamp detection system. Firstly, the composition of the power supply system is analyzed, and the selection of the main circuit parameters and the preionization circuit parameters is emphasized. Then the working principle of series resonant charging power supply and the design of the control and protection circuit of the charger are discussed. According to the functional requirements of the power supply control system, the software design of the xenon lamp detecting power supply system is analyzed, and a set of remote computer control software and a set of field PLC control program are designed. The control software can automatically run according to the set number of times and fixed time intervals, and can protect the faults in the running process of the power supply system. The control software is tested to verify the stability, accuracy and reliability of the algorithm. This paper also discusses the importance of EMC design and the improvement of the Xenon lamp detection power system in EMC. According to the technical requirements of high power pulsed xenon lamp detection system, the system needs to be automatic control, load failure automatic judgment, automatic recording of operation data, and need to ensure the reliable operation under the condition of long-term continuous operation. In order to meet the above requirements, the system adopts a mature technical route, the power supply of PLC is isolated, and the input and output signals are isolated by photoelectric isolation and other technical measures. In order to protect the power control system from the complex electromagnetic environment failure. The secondary coupling technique is adopted in the design of the system data acquisition function, which greatly reduces the interference brought by the current circuit to the acquisition function unit. In addition, the off-line power supply method is used in the data acquisition function unit. In order to ensure the data acquisition to avoid the interference brought by the power grid, improve the reliability of the data acquisition unit.
