The Control System for Lighting Based on Single–chip puter
Abstract
With the rapid development of electronic technology, the system of control based on Single-chip puter is widely applied in industry, agriculture, electric power, electron, intelligent building and so on. puter, as the subject and core of the embedded system of control, replaces the traditional system—electronic circuit. At the same time, the development and maturation of the intelligent building have established the substantial foundation for the popularization and application of the control system for lighting based on single-chip puter。
In this paper,the Indoor Lighting Control System Based on AT89C51 and its principle are introduced. Some effective and energy saving control strategys of lighting system are brought forward. The current system uses a relatively mature sensor technology puter control technology ,using multi-parameter to achieve the school classroom indoor lighting control.
The system includes hardware and software design in two parts. The host controller of the control system for lighting is based on AT89C51 single-chip puter, and the auxiliary ones are based on AT89c51. The system can do many jobs, such as munication, wireless data transmitting, controlling and display. The paper describes the designing process of the circuit at length, including: keyboard and LED display circuit, munication circuit, wireless transmitting circuit, control circuit of lighting, watchdog circuit, etc
