Embodiment approach
[0033] As a preferred embodiment of the present invention, the single-chip microcomputer uses integrated circuit technology to integrate functions such as a central processing unit with data processing capabilities, a read-only memory, and a display drive circuit and an AD converter into a single silicon chip. A small but perfect microcomputer system constituted.
[0034] As a preferred embodiment of the present invention, the AD conversion function means that when the single-chip microcomputer measures the voltage of the photosensitive detector, the voltage value is first converted into a numerical value by the AD conversion circuit, and then this numerical value is sent to the single-chip microcomputer, and the single-chip microcomputer is calculated. After processing, output the voltage value of the photosensitive detector.
[0035] As a preferred embodiment of the present invention, the photosensitive detector outputs different voltage values according to different light...

The invention relates to a signal processing method of a light-controlled lighting fixture. The processing method includes the following steps: reading the ambient brightness voltage value; determining the ambient brightness threshold value; turning on the light-controlled lighting fixture; reading the voltage value again; determining the reference voltage value; judging whether to turn off the lighting fixture. The invention uses the AD conversion function of the single-chip microcomputer to read the ambient brightness voltage value, so that the lighting and extinguishing of the lamp can be accurately controlled according to the natural light intensity of the environment; the invention senses the light intensity through the light sensing module, and converts the light intensity into a voltage Signal, light-controlled lighting signal processing method is simple and convenient, when the light change is detected, the lighting module is controlled to illuminate, the control method is easy to operate and high in efficiency; It is misjudged as a daytime problem, thus avoiding the occurrence of light flickering.
Description
technical field [0001] The invention belongs to the technical field of signal processing of light-controlled lighting fixtures, and in particular relates to a signal processing method of light-controlled lighting fixtures. Background technique [0002] In recent years, with the rapid development of electronic technology, people always hope to be able to change the light on and off according to the intensity of external light. For example, street lights in cities or lights in corridors always hope When the light is strong, the lamp is turned off, and at night, the lamp can be turned on. For example, the emergency light after a sudden power failure, it is hoped that the emergency light will be turned on when the lamp suddenly goes out. The existing solution to this problem is to use Manually operate the lamps. When the lamps need to be lit, the lamp switch is manually closed. When the lamps need to be extinguished, the lamp switch is manually disconnected. This manual operatio...
