基于PIC16F73的广告窗控制系统开发

Development of Billboard Control System Based on PIC16F73

开发了一种广告窗控制系统,以PIC16F73单片机为核心控制器,具有时钟、温湿度测量、语音播报、LED点阵屏显示、自动照明等功能。内部时钟精度高,LED点阵显示屏循环显示当前地名、时间、温度、湿度等信息,利用超声波接近开关能自动判断是否有人靠近,有人靠近时能对显示屏上的信息进行语音播报,定时翻转展示窗中的广告画。与传统的站台广告窗相比,该控制系统能使广告窗更加人性化和智能化,表现效果更好,成本低廉,具有推广应用价值。

A kind of billboard control system is developed with PIC16F73 MCU as the central controller,and this billboard has the functions as clock,temperature and humidity measurements,voice broadcasting,LED dot matrix display,and auto lighting etc.The internal clock has a high precision.The LED dot matrix display displays the information of local place names,time,temperature and humidity information etc.Sonar proximity switch is used to judge automatically whether there is a person approaching.If someone approaches,the billboard will read out the data on display.Pictures on display for advertisement will be changed on a given time periodically.Comparing to traditional station billboard,this one is more human-oriented and intelligent,and has better presentation effects,and lower cost.It contains the value for wider application.
