34、便。智能化道路照明系统能够根据不同区域的不同功能需求，在每天不同时段、不同自然光照度或者不同交通流量情况下，按照特定的设置，实现对道路照明的动态智能化管理，即TPO管理(TIME时间PLACE地点OCCASION场合)。智能化道路照明控制系统，通过综合考虑和分析与道路照明密切相关的时间、路段、环境照度和交通流量等因素的场景控制方法，在微机中按照预设的控制策略，对道路照明进行动态智能化管理，控制路灯在不同情况下工作在不同状态实现多样化的道路照明场景，从而在提高照明质量的同时获得最正确的节能效果。1.系统硬件设计控制电路主要完成对光线、温度信号的采集，数据的运算和分析，以及根据运算结果控制路灯驱动
35、电路。电路需具有MD转换功能，采用STCl2C5608AD单片机作为控制单元，该单片机为单时钟周期增强型8051内核的单片机，片内含8KB的FLASH程序存储器，有8路lO位MD转换接口，可满足数据采集的需要。光强度、温度传感器分别采用光敏电阻和热敏电阻。如图一所示： 图一 图二光敏电阻Rx与电阻R2组成分压电路，光强变化时，单片机P1.7引脚输入电压变化，P1.7引脚可设置为MD转换接口，为光强设置一个临界电压即可区分白天和黑夜。热敏电阻Rx与R3组成分压电路，温度变化时，P15引脚电压变化，经图1控制电路绿色质量观察L NAD转换可计算实际环境温度，以修改时间控制参数。s1为4位拨码开关，
36、可用于认为设定参数，以增加控制器的灵活性。1.1 硬件设计系统硬件模块包含：控制模块，采用STC 89C51单片机实现；传感器模块，采用光敏电阻实现对周围环境光照度的采样，采用光敏二极管通断进行路灯设备故障的检测；时钟模块，采用DS1302时钟芯片；显示模块，由4个LED数码管组成，用来显示故障路灯的编号；声光报警模块，块，用于传输来自上位机的指令。1.2 模块功能STC 89C51单片机根据时钟芯片DS1302提供时钟信号，按照以下时段实现时控开关灯空。1冬季时间：黄昏18：00开灯，次日早晨7：30关灯。2春秋季时间：黄昏19：00开灯，次日早晨6：30关灯。3夏季时间：黄昏20：00开灯
37、，次日早晨5：30关灯。这个时段可动态修改，修改操作在上位机完成，通过通信模块将指令写入STC89C51芯片内，随即就改变了时控开关灯的工作时段。光敏电阻，受到适当波长的光线照射时，电流就会随光强的增加而变大，从而实现光电转换。通过ADC0832器件进行模数转换后提供应单片机，STC 89C51按照预设的方案实现如下光控路灯开关功能。1自动测光，白天或光线强时，夜晚或光线暗时路灯自动点亮。2感光度可调，可根据需要调节在任意光线下工作。3为防止瞬间强光的干扰，特设延时关闭功能光线到达强光时，开关延时30秒左右才自动关闭。光敏二极管是利用硅PN结受光照后产生光电流的一种光电器件，工作于反向偏压。白
38、天受光照或路灯直接照射时光敏二极管反向电阻减小，二极管导通；光照很小时光敏二极管反向电阻增大，二极管截止。采用光敏二极管，检测夜晚路灯是否正常工作。当光敏二极管截止时说明路灯设备故障或被盗，STC 89C51启动声光报警装置，同时在4位LED数码管上显示相应的路灯编号。2.软件设计本系统的软件设计分为七局部，主要包括LED数码管显示程序设计；光照度检测程序设计；设备故障检测程序设计；时钟芯片驱动程序设计；开关灯程序设计；通信程序设计；声光报警程序设计等。软件程序包括：主程序、系统初始化子函数、AD转换子程序、通讯处理子函数、键盘处理子函数、经纬时钟计算处理子函数、拨码开关处理子函数、开关量输入
39、处理子函数、开关量输出处理子函数、显示处理子函数。单片机的软件编程以CodeVisionAVR C编译器作为开发平台，采用C高级语言编写。3.结束语采用无线收发模块与单片机的集成设计，可降低系统的硬件本钱，安装方便，易于维护。采用STR一15型微功率无线数传模块、高效前向纠错信道编码技术，提高了数据抗突发干扰和随机干扰的能力。采用高速单片机W7E58，提高了液位的测量精度，简化了系统的硬件结构。该系统不仅对液位测量是一种平安、有效的解决方案，也可以应用于其它恶劣环境下的物位测量。路灯系统是道路交通不可缺少的照明设施，设计一种智能化路灯控制系统，对提高道路的诱导性，提高夜间行车的平安感和舒适感，
