The invention provides an optical fiber remote end power supply system with a safety protection device and an implementation method of the optical fiber remote end power supply system. The optical fiber remote end power supply system comprises a source end for converting electric energy into optical energy, a remote end for converting the optical energy into the electric energy for application or storage, an optical fiber channel for transmitting the optical energy and a communication signal between the source end and the remote end, and the safety protection device for monitoring whether the whole optical fiber remote end power supply system normally works or not in real time; the safety protection device comprises a detection module, a feedback module and a control module; the detection module detects an electric signal in a photoelectric conversion module at the remote end in real time; the feedback module processes the detection result of the detection module and sends an alarm signal to the control module when voltage or current is lower than a set value; and the control module stops running of the photoelectric conversion module. According to the optical fiber remote end power supply system, the safety protection measures of the system are completed while optical fiber remote end power supply is achieved; a power supply network is effectively protected; and the fireproof and explosion-proof targets and the target of protecting the person and property safety are achieved.

Description

technical field [0001] The invention relates to the technical field of transmission equipment safety protection, in particular to an optical fiber remote power supply system with a safety protection device and an implementation method thereof. Background technique [0002] Optical fiber remote power supply system is a system that uses optical fiber as the transmission medium to convert electrical energy into optical energy for transmission. Compared with traditional power transmission, the use of optical fiber to transmit energy has the following advantages: (1) It only transmits light and does not conduct electricity, is less affected by electromagnetic interference, is safe and has low loss, and can be used in flammable and explosive places. (2) The transmission medium is light, the volume is small, the source of raw materials is wide, and the corrosion resistance is strong, the service life is long, and the transmission loss of the optical fiber is not affected by the tem...

Problems solved by technology

When ordinary optical fibers are used for communication, the transmission power is at the level of milliwatts, which is in the laser safety standard of Class 1 or Class 2 lasers, while the optical power used for optical fiber remote power supply systems is on the order of 500 milliwatts or more, which is in the Class 4 laser, if there are no corresponding safety measures, will cause great damage to human eyes and skin, and may cause fire. Therefore, the safety protection problem of the optical fiber remote power supply system needs to be solved urgently, which is also the key to the optical fiber remote power supply system one of the techniques
