[Abstract]:After many years of development, the space environment exploration has acquired a large number of exploration data on the sun and earth space, planets and the moon. The safety of space engineering activities is ensured by analyzing the effects of the exploration data. Among them, solar X-ray detection is an important part of space environment detection. The development of solar soft X-ray detector based on SDD requires a set of perfect, high precision, ultra-low noise level, high intelligence, high reliability and safety ground detection support system. The main work is to establish and perfect the intelligent detection system of the solar soft X-ray detector based on SDD sensor, to carry out strict and accurate inspection and examination of the SDD sensor which is used in the space mission before going into space, and to improve the reliability of the development of the onboard equipment. High efficiency. This paper analyzes the physical requirements and the design scheme of the intelligent detection system for the solar soft X-ray detector. It mainly introduces the electronic hardware and software design of the front-end readout circuit system and the FPGA main control system of the X-ray detector. Under the control of FPGA, the data acquisition unit acquires the output signal of the front-end detector, analyzes the amplitude of the acquisition through the back-end analog-to-digital conversion, and transmits it to the computer through serial communication. And in the computer interface real-time display. The experimental results show that the proposed scheme meets the requirements of the electronic system of the solar soft X-ray spectrometer, and the basic intelligence of the equipment system for SDD sensor screening, performance evaluation and reliability evaluation is completed. The accuracy and noise level control are improved. Finally, the research process of the intelligent detection system of solar soft X-ray detector is summarized, and the technology of solar soft X-ray detector based on SDD is prospected.
