Speech based on single chip bus stop reporter system
Abstract
With the development of national economy and the deepening of the process of urbanization. The pressure on city traffic is increasing because of the Increasing urban population and the Sharp increase in motor vehicles. Development of public transport is the Irreplaceable way for the Residents safe and orderly travel. The high-quality of Public transport management and public services is a effect way to attract People take bus. and the important measure for China to solve the traffic problems. The bus stop device is a very important Part of Public transport system. The Advanced design of the device can serve people well and improve the Service level of public transportation systems.
At present, the city buses have generally installed the station voice system which gives the passengers a very comfortable experience. However, most of the system is manual. The driver have to control it when the car entering and leaving the station. At this time, the traffic condition is so complicated that it usually brings security risks. The paper design a bus automated voice system with Atmel Company’s AT89C51 single-chip. Using JHD162A LCD to display the station's information, ISD1700 series voice chip controls the voice paragraph and DF wireless transceiver module,PT2262/PT2272 chip to achieve the signal's wireless transmission and identification. Finally, all the modules are controlled by AT89C51 and the simulation of the system.
