【摘要】 本文提出用光纤型光电耦合器传送阶梯信号。用二根光纤型光电耦合器(一根传送控制信号,一根回收试验数据)串行传送由十五位数字量组成的试验数据。设计了简单的IBM—PC微机系统的专用输入/输出接口。所以,本数据处理系统光纤型光电耦合器用量大为减少,价格便宜。由于数据采用串行传送,因而使IBM—PC微机系统可以远离高电压试验现场而独立工作。消除了冲击放电对微机系统的干扰,提高了微机系统正常工作的可靠性,还为微机对冲击电压试验的远距离控制打下基础。更多还原

【Abstract】 In this paper a method using the optic—fiber link to transmit a step pulses is presented. Data transmission is performed by two fiber links and a special I/O in terrace is designed for IBM—PC microcomputer processing system so that the system has a small number of fibers and the cost is low.This IBM—PC on—line data processing system can be remotely operated far away from the area of the inpulse tesl, therefore the interference clue to impulse sparks may be.ignored and the reliability of the microcompter system can be greatly improved.The present work lays the foundation for the remote control of the impulse test with microcomputer.更多还原
