Abstract

The system comprises: a charging and lighting circuit composed of solar cell, storage cell and lamp. The solar cell in the system is parallel-connected to MOSFET Q1 and charges the branch of the storage cell via diode D01; the storage cell provide the illumination power for the paralleled lamp branch, the MOSFET Q2 and Q3 paralleled-connected on the lamp branch ; on said charging branch and the parallel lamp branch, the sampling resistor R42, R40 and R41 are respectively mounted; the control circuit in the system comprises a MPU for detecting the voltage of solar cell, voltage of storage celland current of lamp branch and controlling the charging output of the solar cell and the output of two route lamps; said MCU chip is used to make self-test for the system; the failure signal is display by LCD.

Description

technical field [0001] The invention relates to a solar street lamp control system, in particular to a solar street lamp control system with fault self-check display. Background technique [0002] As the world's energy crisis continues to intensify and non-renewable energy sources become increasingly tense, more and more countries pay attention to the use of solar energy, wind energy, and tidal energy to generate electricity. Among other energy sources currently known, solar energy is the safest and most convenient. , One of the clean energy sources. Since the price of solar cells is still high, the most widely used field is solar lighting applications. [0003] CN2571116Y discloses a power supply system control device for solar street lamps. It uses the microprocessor to start the load with the voltage generated by the solar panel to detect the ambient brightness, determines the charging timing according to the voltage difference between the solar panel and the battery, an...
