However, the operating environment of drone aerial survey is often complex and changeable, which places strict requirements on the design and performance of photocouplers.
[0003] Drones may perform tasks in harsh environments such as high temperature, low temperature, strong wind, rain, and dust. Especially under high humidity conditions, water vapor can easily penetrate into the optocoupler, causing the chip to get damp, affecting its normal operation, or even causing permanent damage. In addition, the inevitable vibration and impact during flight may also damage the structural stability of the optocoupler and the internal precision chip, shortening its service life.
