The invention discloses an optical fiber lighting intelligent illumination system. An MSP430F149 single-chip microcomputer is connected with a direction detection module, a voltage stabilization circuit, a charging and discharging switching circuit and a transmission device. The transmission device is connected with a lightning device which is connected with a light guide device. The voltage stabilization circuit is connected with the direction detection module and the charging and discharging switching circuit. The charging and discharging switching circuit is connected with an LED illumination module, a switch power supply module, a storage battery A, a storage battery B and a solar charging controller. The solar charging controller is connected with a solar cell panel. The direction detection module detects the deviation angle, relative to sunlight, of the lightning device. The single-chip microcomputer receives signals detected by the direction detection module and drives a pan-tilt of the transmission device to act so that the lighting device can be accurately aligned with the sun. Meanwhile, charging and discharging switching is achieved by controlling the charging and discharging switching circuit according to the electricity amounts of the storage batteries. The optical fiber lighting intelligent illumination system has the advantages that cost is low, and zero energy consumption is achieved.
