智能单片机照明灯控制器设计：节能智控，科技光明

In the document "Design of Intelligent Lighting Controller Based on Single Chip Microcomputer", the night lighting system adopts the AT89S52 single-chip microcontroller as its core, using the microcontroller's ports to control the LCD1602 standard clock system, thyristor, and electric bell separately, achieving intelligent control of the lighting system. Common lighting fixtures in public places such as street lights, corridor lights, lawn lights, advertising box lights, neon lights, and toilets often remain lit all night, not only wasting energy but also causing light pollution to some extent. In today's situation where electricity supply is tight, turning off these lights at night when there is no human activity can save energy and reduce expenses. The document first introduces the background and significance of the system development, emphasizing the process of hardware and software design. In terms of hardware, it elaborates on components, modules, and system gradually, especially focusing on the core part of the system, the AT89C52, and uses PROTEL 99SE software for schematic and circuit board design. In software aspects, popular nowadays in single-chip C language programming, using timer interrupts to control the standard clock. Lastly, the document discusses hardware and software debugging, including the use of the single-chip microcontroller simulation software KEIL C51. Keywords: AT89S52, thyristor, AT89C2051, LCD1602, photoresistor, KEIL C51, PROTEL 99SE.
