In order to satisfy the pluse hydrogen thyratron aging test system control requirements, to overcome the severe electromagnetic interference environment, build a control system based on PC-PLC, introduces the composition and working principle of the testing system. Design of PC-PLC control system, accomplishes remote control of thyratron trigger system, out of adjustable repetitive rate pluse, and measure the performance parameters of the thyratron in remote real-time. The optical fiber communication technology was used for transmitting the thyratron trigger pulse to enhanced the trigger system＇s antijamming ability; using VB to develop user interactive interface for PC design and testing. Test results show that the control system in high pressure strong electromagnetic interference environment, reliable operation, stable, accurate communication, real-time, system function and technical indicators can meet the design requirements.
