Title Intelligent street lamp control system based on single chip microcomputer
Abstract
Single chip microcomputer has the advantages of small volume, small mass, strong anti-interference ability, low price, high reliability, good flexibility and easier exploitation, having high cost performance, so it has been widely used in street lamp control system. This paper studies the intelligent street lamp control system based on single chip microcomputer.It combines functions of time control, light control, temperature and humidity measurement and alarm in one.It can better solve the problem of waste of resources as well.
The system is consisted of single chip computer control unit, DS1302(real-time clock), DHT11(temperature and humidity measurement), light intensity detecting and LCD display module.This paper introduces the overall design, hardware circuit design and software programming, and elaborates the interface function and working principle of each module. By practical testing, the system can achieve the design purpose.
Keywords SCM intelligent street lamp control system working principle hardware circuit software programming
