【摘要】 报道红外辐射器能效测试仪的电功率测量系统和微机系统的研制。电功率测量系统采用“等效功率计”法实现,简单易行、使用方便;微机系统用于数据处理和结果显示,采用MCS—51单片机系统,硬件设计简单,尽可能使硬件软件化。通过功能选择,本测试仪可分别测试辐射器的红外辐射转换效率和辐射功率,且可检测辐射器的局部辐射均匀性。更多还原

【Abstract】 This paper reports the development of both the system of the electric power measurement and the system of microcomputer for the instrument. The system of electric power measurement is realized by means^of "equivalent dynamometer". It is single and convenient to operate; the system of microcomputer is for dealing with the data and showing the results. It is because the system of MCS-51 singlechip microcomputer is employed that the hardware is briefly designed and realized by as much software as pdssible. By the choise of function, the instrument can pe used for measuring the efficiency of the infrared radiation and the radiation qower of radiators and for testing radiators for the evenness of the partial radiation.更多还原
