兰州工业学院毕业设计说明书（论文） PAGE PAGE 14 摘 要 本文介绍了一个模拟路灯控制系统的应用方案，用以实现模拟路灯的智能控制。本方案以AT89S52为核心，加以简单的外围电路，实现了模拟路灯控制系统所要求的全部技术内容。单片机在最近几年应用越来越广泛，因其抗干扰能力强、稳定性好，性价比高，因此是低成本路灯控制解决方案的首选。该控制系统除了选用廉价的单片机芯片，还采用了廉价的红外对射传感器，大大降低了系统成本。整个系统的电路简单，结构紧凑,电源驱动仅采用变压器与三端稳压器相结合，附加少许滤波电容便实现了稳定的电源输出。经过多次测试，证实该系统能长时间稳定工作，完全满足设计要求指标。 关键词：模拟控制；LED照明；单片机 ABSTRACT This paper introduces a simulation control system application scheme street, to simulate the street lamp of intelligent control. This plan to macro crystal company AT89S52 as the core, to chip the periphery of the simple circuit, realize the simulation street lamp control system all of the requested technology content. STC SCM in recent years more and more wide application, because of its strong anti-interference ability, good stability, high performance/price ratio, and so is the low cost street lamp control solutions of choice. The control system in addition to choose cheap single-chip microcomputer chip, also adopted the cheap infrared mutual illuminate sensor, and greatly reduce the cost of system. The whole system of the circuit is simple, compact structure, power drive only used three transformer and the regulators, and the combination of a few additional filter capacitance will realize the stable power output. After many test, and confirm that the system can work stably for a long time, fully meet the design requirements index.
