摘要
当今社会公交车成为一种必不可少的交通工具,公交车报站器在公交事业中占有举足轻重的地位,它直接影响到公交车的服务质量。介绍了一种可视/可听公交车自动报站系统的设计,以AT89S52单片机为核心,通过8255芯片扩展外围接口,采用ISD4003语音芯片进行语音播放,同时使用LED点阵电路进行汉字显示,实现了公交车的语音自动报站以及汉字显示提示的功能。经过实际测试,报站系统运行稳定,抗干扰能力强,并且操作简便,成本低廉,适合于公交车领域的普遍应用推广。
Nowadays, public bus has become an indispensable means of transport. The bus station is in the public transport industry occupies a pivotal position, it directly affects the quality of service of the bus. This paper introduces a Visible and audible bus automatic report station system design, by AT89 S52 microcontroller as the core, through the 8255 chip expansion peripheral interface,the ISD4003 voice chip for voice playback, also use circuit of LED dot matrix Chinese character display, achieve hint as to the function of bus voice automatic newspaper station and Chinese character display. Through the actual test, the newspaper station system has stable operation, strong anti-interference ability, and simple operation, low cost, suitable for the general application in the field of public transport.
