基于多机通信的智能照明系统的设计

基于多机通信的智能照明系统是一种楼宇照明控制系统，能够实现人工灯光控制、自动灯光控制、定时开关、节能模式控制等功能。该系统以PC机作为上位机，MCS-51单片机作MCU，结合传感器和多机通讯功能，总体结构分为两个层次，其中主单片机与PC机之间通过API接口进行通信，而主单片机与从单片机之间可采用广播或点对点的通信方式，主机以查询方式工作，从机以中断方式工作。既可通过光敏电路检测到的光线信息自动调整照明状态。也可人工设置各照明点的照明状态。

The design of intelligent lighting system based on the Multi-machine communications

The intelligent lighting system is a building＇ s lighting control system based on the Multi-machine communications, which will realize the controlling of artificial and automatic lighting, lighting control, energy-saving mode, timer switch. The system uses PC machine as host machine and MCS-51 single-chip as MCU, combined with sensors and Multi-machine communications, the overall structure is divided into two levels, the main single-chip communicates with the PC machine via the API interface, and the main single-chip communicates with the sub single-chip can adopt the broadcasting or point-to-point communication mode. Host computer works by the query mode and sub computer works by the interrupt mode. Using the light information, which detected by the photosensitive circuit, the system is able to adjust the state of the lighting automatically, as well as adjusting it artificially.
