Signal processing type double-power-supply energy-saving passageway illumination system

Abstract

The invention discloses a signal processing type double-power-supply energy-saving passageway illumination system. The system is characterized by being mainly composed of a central control unit, a double-power-supply switchover switch, an illumination lamp, a frequency correction circuit, an analog-to-digital conversion chip, a switch voltage-stabilized power circuit, a storage battery, a solar cell panel, a hybrid prefixed amplification circuit, a light sensor and the like, wherein the double-power-supply switchover switch, the illumination lamp and the frequency correction circuit are connected with the central control unit, the analog-to-digital conversion chip is connected with the frequency correction circuit, the switch voltage-stabilized power circuit and the storage battery are connected with the double-power-supply switchover switch, the solar cell panel is connected with the storage battery, and the hybrid prefixed amplification circuit, the light sensor and the like are connected with the analog-to-digital conversion chip. The frequency correction circuit can conduct frequency correction on signals output by the analog-to-digital conversion chip, and it is avoided that frequency fluctuation affects normal work of the system. Under a normal condition, power of the system is supplied by a power grid, and a solar power supply serves as an auxiliary power supply; when the power grid cannot supply power normally in an emergency, the solar power supply can supply power to the system by means of switchover, and therefore it is ensured that the illumination lamp in a passageway can work normally.

Description

technical field [0001] The invention relates to the field of energy saving, in particular to a signal processing type dual power supply corridor energy-saving lighting system. Background technique [0002] At present, the traditional corridor lighting system is powered by mains power. However, in case of emergency, the mains power is often unable to supply power to the corridor lighting system normally, making the corridor lighting unable to work, which brings great inconvenience to the lives of residents. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the traditional corridor lighting system will affect the work of the lighting lamps when the mains power cannot be supplied normally, and provide a signal processing type dual power supply corridor energy-saving lighting system. [0004] The purpose of the present invention is achieved through the following technical solutions: a signal processing type dual power supply...
