Embodiment
[0022] Such as figure 1 As shown, the frequency-corrected corridor energy-saving lighting system based on dual power supplies of the present invention is mainly composed of a central controller, a dual-power switch, a lighting lamp, and a frequency correction circuit connected to the central controller, and the frequency correction circuit. A connected analog-to-digital conversion chip, a switching regulated power supply circuit and a storage battery respectively connected to a dual power supply switch, a solar panel connected to the storage battery, and an infrared sensor and a light sensor respectively connected to the analog-to-digital conversion chip.
[0023] Wherein, the central controller is used as the control center of the present invention, and its preferred STC90C52AD single-chip microcomputer is realized. The infrared sensor can detect whether there are pedestrians passing in the corridor, and the LH1958 infrared sensor is preferred. The light sensor can detect th...

The invention discloses a frequency correction type corridor energy-saving illuminating system based on dual power supplies. The system is characterized by being mainly composed of a central control unit, a dual-power-supply changeover switch, illumination lamps, a frequency correction circuit, an analog-digital converting chip, a switch voltage-stabilizing power supply circuit, a storage battery, a solar cell panel, an infrared sensor, a light sensation sensor and the like, the dual-power-supply changeover switch, the illumination lamps and the frequency correction circuit are connected with the central control unit, the analog-digital converting chip is connected with the frequency correction circuit, the switch voltage-stabilizing power supply circuit and the storage battery are connected with the dual-power-supply changeover switch, the solar cell panel is connected with the storage battery, and the infrared sensor and the light sensation sensor are connected with the analog-digital converting chip. Under normal conditions, power supply is achieved through a power grid, a solar power supply serves as an auxiliary power supply, when the power grid can not normally supply power in emergency, the system can be powered by the solar power supply instead, and therefore it is ensured that the illumination lamps in corridors can normally work. By means of the frequency correction circuit, frequency correction can be conducted on signals output by the analog-digital converting chip, and it is avoided that the normal work of the system is influenced by frequency fluctuation.
Description
technical field [0001] The invention relates to the field of energy saving, in particular to a frequency-corrected corridor energy-saving lighting system based on dual power supplies. 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 frequency-corrected corridor energy-saving lighting system based on dual power supply. [0004] The purpose of the present invention is achieved through the following technical solutions: a frequency correction energ...
