Design and implement of communication and data transmission system for ultraviolet limb imaging spectrometers
摘要
Abstract
In order to ensure that the ultraviolet limb imaging spectrometers can finish the engineering task satisfactorily,monitor and research the earth limb spectrums,the communication and data transmission system was designed and implemented.Firstly,the structure and the operating principle of communication and data transmission system were introduced.Secondly,the function of communication was designed in detail,the fault diagnosis and treatment method based on communication timeout and data error was proposed.Then,the function of data transmission was designed in detail,the data transmission method based on 8b/10b was proposed.Finally,the experimental results of orbital flight were analyzed.The experimental results indicated that communication and data transmission system could realize the instruction communication and scientific data transmission.The data transmission frequency of annular spectrometer was 80 MHz,the data transmission frequency of forward spectrometer was 40 MHz and the performance test results satisfied the requirements of technical indexes.The results of RS-422 serial communication indicated that the delay error between byte and next byte was no more than 2 ms,the delay error between receiving message and feedback message was no more than 5 ms,which effectively improve the continuity,timeliness and reliability of communication system.关键词
