基于单片机的地下车库车位监测系统的设计

摘要

This paper presents a new underground parking monitoring system based on MCU ,used in the real time monitoring of the underground parking garage .The system is based on MCU ,collectingvoltage signal of silicon photovoltaic cells before and after the illumination light signal is blocked ,processing silicon photocell voltage signal using the voltage comparator circuit .At last , the electrical signal after treatment is transmitted to the MCU ,and real time data is displayed on the LCD screen .The system com bines silicon photovoltaic cells and garage lighting to enhance the value of the illumination light ,achieving real time monitoring of parking information ,so that it can improve the operational efficiency of the garage .%提出了一种基于单片机的地下车位监测系统，应用于地下车库车位实时监测。该系统以单片机为基础，采集车位照明灯光信号被遮挡前后的硅光电池的电压信号，用电压比较电路处理硅光电池的电压信号，并将处理之后的电信号传送至单片机，最后将车位实时数据在液晶屏上显示。本系统将硅光电池和车库照明系统有机结合起来，提升了照明灯光的应用价值；实现了车位信息的实时监测，提高了车库的运作效率。
