Light triggered switch in high temperature environment

  • 摘要: 针对在高温环境中测试仪器的供电方式问题,利用光敏二极管响应时间短并对光灵敏的优点,将其作为供电电源的开关,吸收高温辐射源发出的红外光信号,通过光电转换,使电源导通,达到开关的效果。文中阐述了这种光控的供电方式的理论依据和实现方式,排除了日光等因素的干扰,并对该方法进行了验证。通过试验证明,该方法操作简单,实用性强,很适用于一些不适合人为操作的场合。
    Abstract: To provide a power supply for a test instrument operating at high temperature environment, a scheme of using a photodiode as the switch of the power supply was developed, which had the advantages of short response time, high sensitivity and so on. The photodiode received the infrared ray emitted by the high-temperature emitter, the power was switched on after optical-electric conversion, and the desired results were achieved. This paper introduced the concept of the optically controlled switch and its implementation. The simplicity and feasibility of the design was verified by experiment results, and it is suitable for some operations not accessible by human being.
