一种粘贴式LED公交智能站牌

Intelligent Bus Stop Board of Bonded LED

设计了一种城市智能公交站牌,给出系统软/硬件设计方案。该系统以STC12LE5A60S2芯片为控制核心,通过SIMCom有限公司的SIM900A芯片对公交信息服务器发送的GPRS数据进行接收,并通过站牌上LED灯的闪、亮、灭显示此线路上游来车位置信息。LED灯通过粘贴方式粘贴在现有公交站牌的站点名称上方或下方,可为乘客提供方便、直观的公交实时位置信息,经济性好,易于改造施工。

A intelligent bus stop board was studied,and the design schemes of software / hardware system were projected. The main content of this study uses STC12LE5A60S2 chip as control core,deals with the received information from SIM900 A chip provided by SIMCom and controls the LED,which showed the vehicle＇s position message.The SIM900 A clip,as the public transport information clip,receives and sends the bus＇ s GPRS data. And the LEDs were stuck to the bus stop board,which was corresponding to each site name,and showed the real-time location information about the upper stream buses. The new board design can provide more convenient,more intuitive service for passengers,which has well economy and ease of reforming the construction.
