Abstract :With the City "bus priority" to implement the strategy, the establishment of a complete and scientific system of the intelligent public transport, urban infrastructure has become established trends.
This paper presents a signal through the records of vehicles to get location information, the use of GSM radio relay transmission system design, greatly reduces the cost and operating expenses, is to achieve the best urban public transport smart choice. E-stop licensing system will not only facilitate passengers travel, but also played a role in information transmission link. Voice E-stop is the humanities in today''s society, science and technology development came into being to facilitate the travel of a hi-tech products, as people''s lives is a big convenience, but also reflects the development of China''s science and technology can be flexible use in the lives of people. From now on, the visually impaired people travel by bus will be like normal people to enjoy the public brought about by information technology facilities. Voice E-bus is a bus stop e-station extension of the licensing system of products, from the host control unit and wireless communication module and other related equipment constituted. Through the wireless communication module, type in high-risk information about bus lines, bus stop voice electronic voice device after receiving the services directive, public e-points will be issued a license on the vehicle arrival information to the form of broadcast voice.
The system of 51 series single-chip microcomputer to control the core of the system with forwarding instructions, data backup and transfer, operation tips and other functions, wider adaptability, particularly suitable for computer peripherals and backup for data collection. : The AT89C51 single-chip, design methods, design of a good real-time and stable operation.
Key words:AT89C52 single-chip computer; voice broadcast; GSM module
第1章 引 言
随着电子技术的飞速发展,在人们各种生活领域中也更多的接触到了这些。同时数据采集、发送也越来越多的与我们的生活生产发生联系,如何将数据采集、发送运用于生活中,并为人们的出行提供方便是本系统所要解决的主要问题,本文介绍一种通过接收、发送车辆信号来获得位置信息,采用GSM无线收发系统设计,大大降低了成本和运营费用,是实现城市公交智能化的最理想的选择。系统中电子站牌不仅方便乘客出行,还起到了信息传输纽带的作用。
本设计主要以AT89C52为主机芯片,通过GSM芯片对其进行控制,并由键盘显示及语音芯片同时作用,不但成本比较低,而且使用方便。
