Safety protection method for optical fiber power supply system

Abstract

The application discloses a safety protection method suitable for an optical fiber power supply system, wherein a gateway device sends a ranging request signal to a terminal device according to a preset frequency and provides optical energy required by the terminal, and determines the sending time, signal power and modulation mode of the terminal device according to the transmission quality of the ranging request signal. The gateway device can adjust and alarm a request signal through the terminal device, can realize real-time sensing of the change of optical energy signal transmission parameters of an optical fiber channel when remotely providing electric energy for the intelligent terminal in the optical fiber power supply communication system, so that the gateway device and the terminal device provide electric energy to an external intelligent device in an optimal mode, and mutual matching of the change of optical energy power output by the gateway and the power parameter of the external intelligent device is ensured.
