摘要
为实现公交车的自动报站功能,提出一种以C8051F040单片机和GPS卫星定位系统的设计方案。首先设置通过录音接口预存各站点具体位置的语音信息,当公交车在行驶时,能自动识别站点并完成语音报站功能,同时可设置公交车行驶的上限速度,当超过该速度值时,系统将完成语音报警提示。该系统定位准确,并可实现全天侯工作。
A vehicle-mounted system with C8051F040 MCU as the control core is designed based on GPS and used to realize automatic bus station announcement. Firstly, voice information of each station is recorded by a sound recording inter- face. The system automatically indentifies next station and reports the station name, while the bus is driving. At the same time, maximum of driving speed is set. Once the bus exceeds the set speed, the system completes the function of voice warning. In addition, the system has the function of accurate positioning and can operate day and night.
