行人检测方面采用两个热释电红外传感器，通过双限电压比拟放大电路对信号的降噪与放大，将处理后的信号交由单片机处理，判断行人所在区域是否为工作区域。
而太阳位置追踪装置，那么是采用一块硅光电池作为光强检测与一块四象限光电探头作为太阳位置检测。光强信号与位置信号分别通过I/V变换电路与放大电路进行信号的处理与放大，以得到A/D转换器可以识别与分辨的电压信号，A/D转换器将模拟量的电压信号转换为相应的数字量信号，以供单片机比拟与计算，进而对太阳的位置进行跟踪，保证太阳能电池的主光轴与光线平行。
该系统采用的行人检测装置及LED点数控制，很好的节省了蓄电池的能源，降低了蓄电池的损耗，降低了蓄电池更换频率。并且选用精度较高的四象限光电探头与步进电动机配合的太阳位置跟踪装置，能够提供足够的精度，以实现实时跟踪。

Design of intelligent controller of solar street lamp
Abstract
With the development of society and population growth, Mankind is facing the more serious environmental and energy crisis. Many countries have formulated the development strategy,so,the research for the solar street lamp is paid more and more attention. This paper introduces the controller for control of solar street lamp,this intelligent control system with automatic recognition of pedestrians and controls the LED points,It also has the function of automatic tracking solar design has the function of the general solar street lamp controller,like:overcharge protection,overdischarge protection and dual mode power supply。It’s used energy-saving high-power LED as light emitting devices and efficient microcontroller as the it’s also used the photoelectric technology to improve the sensitivity of the system. The system is mainly composed of pedestrian detection and position of the sun tracking.
Pedestrian detection using two pyroelectric infrared sensor, dual-threshold voltage amplifier circuit to reduce noise and amplification signal, then the signal will be processed by the microcontroller and determine whether the pedestrian area in the work area.
The position of the sun tracking device uses a silicon photovoltaic cells as the light intensity detection and a four-quadrant photoelectric probe as the detection of th
