路灯控制电路设计

该路灯控制系统主要由时钟发生电路、路灯控制电路、LCD显示电路、声光报警电路、键盘控制电路和单片机控制电路等部分组成。在时钟发生电路中，采用低功耗实时时钟电路芯片DS1302，它可以对年、月、日、周日、时、分、秒进行计时，计时后，经过单片机的控制处理后从显示屏上将计时的数据显示出来。而路灯控制部分通过对外部环境进行检测，实现不同环境的不同操作，从而实现各个不同功能。由于采用了较高级的时钟控制元件、精度较高的红外检测装置和外界光检测装置，实现了对外部环境的控制功能，而且有效地提高了精度。

Design of the Street Lamp Controlling Circuit

This street lamp system consists of clock circuit, lamp control circuit, LCD display circuit, sound and light alarm circuitry, keyboard control circuitry and single-chip controlling circuit. In the clock section, with the trickle charge current capacity of low-power real time clock circuit chip DS1302, the years, months, days, Sundays, hours, minutes and seconds can be counted, after MCU control processing the timing data will be displayed. Through testing the external environment, the lamp control part will be achieve different operating and various different functions. By using higher clock control components, high precision infrared optical detector devices and the optical detection device, the control function of the external environment was realized and the accuracy was improved.
