Abstract：University of traditional lighting control are ever burning lights, no lights "phenomenon, in order to solve the traditional university classrooms for energy waste phenomenon, specially research the classroom lights use methods and existing disadvantages. This paper uses a simple 51 micro controller based control circuit, coupled with a number of auxiliary circuit modules, to achieve the development and testing of the test system. Including data acquisition module, serial communication module and the implementation of the module circuit design and software development.

Introduction

In nowadays, the world's major problem is still a waste of energy or how to develop a new energy, especially in the late 20th century, many scientists put forward to the idea that our country's policy is energy-saving emission reduction, the energy issue Pushed to the number of problem to solve. Against the background of the above, can deeply feel the school's waste of electricity is particularly serious, especially in many classroom lighting without class, which nobody study hall, but it has been on the lights. So for the kind of building before the cover, this phenomenon is very serious, so wehave toi against this situation. I will study how to solve this problem. I use this article is a simple 51 single-chip microcomputer as the main control circuit, and interspersed with some of the auxiliary circuit module to achieve the test system development and debugging. Including data acquisition module, serial communication module and the implementation of the circuit design and software development.

Basic Design Ideas

For this intelligent lighting system, divided into hardware and software parts. The hardware part mainly uses 51 monolithic integrated circuits as the core component, the main reason is the 51 monolithic integrated circuit price-performance ratio is also high and the stability . The other are some auxiliary modules, such as the clock module, infrared tube module. Software is the main part of the circuit diagram with the simulation, the main use of the C language programming, debugging process plus simulation. And puts forward the concrete realization method for the control strategy of the system. And the use of C language to write programs, and then use the relevant software simulation. The main core of the system design is the choice of the controller.

Option 1: Use the 51 Series as the system controller AT89C51 as a system control program. Because of its low power consumption, small size,

mature technology and low cost, it is widely used in various fields. Because of the advantages of the chip, it can be used in a wide range of applications. Feet less, in the hardware is very easy to achieve. And anti-jamming performance.

Option 2: The MSP43OF149 series microcontroller for the system controller.MSP430F149 series MCU can achieve a variety of complex logic functions, large modules, high density, it will all devices integrated in a chip, reducing the size and improve stability.
