公交车报站系统的设计

第 28 页 共 4 页基于单片机的公交报站系统的设计目录摘要：本文针对公交车上自动报站的这一现实需要，以单片机为核心设计了一个系统，在该系统之中单片机通过对语音芯片的控制进而实现了公交车的模拟语音报站。在这一系统之中采用的 STC89C52 对整个系统之中的硬件进行控制。以 ISD4004 语音芯片为核心建立公交车报站的语音数据库，在报站的过程之中，在单片机的控制之下，语音信息能够实现自由组合，进而能够自主的进行多样化的语音报音；在语音播报的过程之中 LM386 在这一系统之中的作用是拨出语音和相关的提示音，在这一过程之中单片机还可以将站点的相关信息显示在 LCD 液晶显示器之上。本文设计的基于单片机的公交车报站系统具有结构简单，运行流程简洁，使用灵活，在播报的过程之中音质清晰自然等优点，这一系统在社会之中具有一定的实用价值。关键字：单片机，公交车，报站器 Design of bus station reporting system based on single chip microcomputerAbstract：In order to meet the need of automatic station reporting on bus, a system is designed based on single chip microcomputer. STC89C52 is used in this system to control the hardware in the whole system. ISD4004 voice chip is used as the core to establish the bus station voice database. In the process of station reporting, under the control of single chip microcomputer, the voice information can be freely combined, so as to independently carry out diversified voice reporting. In the process of voice broadcast, the role of LM386 in this system is to dial out the voice and the relevant prompt sound. In this process, the MCU can also display the relevant information of the site on the LCD. The single-chip microcomputer-based bus station reporting system designed in this paper has the advantages of simple structure, simple operation process, flexible use, clear and natural sound quality in the process of broadcasting and so on. This system has certain practical value in the society.Keyword：...
