Because of numerous instruments and equipment existing in the radio telescope system and observatory site,the electromagnetic environment becomes complicated and astronomical observations become difficult. Radio telescopes are extremely sensitive systems,and electromagnetic emission from electronic equipment in their neighborhood must be tightly controlled. The Electro-Magnetic Compatibility ( EMC) is concerned with the design and operation of equipment in such a way: they are immune to the Electro-Magnetic Interference ( EMI) while at the same time they do not interfere with other equipment in the same environment. The electromagnetic compatibility design,shielding design and emission assessments are all dependent on the data processing and analysis. Therefore the routinization is the only way to improve the test efficiency and the data analysis. Firstly,the measurement system,the evaluation process,goals and the key technic problems of the software design are analyzed in this paper. Based on the data transfer properties,processing and data storage in the software,the flow chart,data flow diagram and the key interpolation algorithm flow chart of the evaluation software are given. The main data characteristics and the date storage methods of the evaluation processing are also analyzed,then the data storage and management module based on the data source and the database is developed. Secondly,based on the Microsoft Visual Studio 2010 development platform,the electromagnetic radiation evaluation software is developed through lots of program debugging and optimization, which is capable for the rapid test,the analysis and the evaluation of the equipment radiation characteristics, which provides an important reference for the electromagnetic compatibility designing for the radio astronomy observatory. Meanwhile,with the software used,the repeated and tedious testing process and the data process also become easy,greatly improving the data reliability and efficiency for the scientific research. |
