基于AT89C2051单片机的客车倒车监视系统

AT89C2051是美国ATMEL公司生产的低电压、高性能CMOS 8位单片机,采用高密度、非易失性存储技术生产,兼容标准MCS-51指令系统,适合许多高性价比的应用场合。文中采用AT89C2051芯片为北京某汽车公司设计了一个客车倒车监视系统,并介绍了相应的硬件设计和软件编程。只要挂上倒挡,系统便自动监视车后从0.35m至5.0m的视频图像,在客车进站中门打开时,系统会自动监视中门附近车内信息。该系统已投产使用,性能稳定,反应良好。

Back Surveillance System of Passenger Car Based on AT89C2051 Singlechip

The AT89C2051 is a low-voltage,high-performance CMOS 8-bit microcomputer which is produced by the American ATMEL Corporation.The device is manufactured using ATMEL's high-density,nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set.The AT89C2051 provides a highly-flexible and cost-effective solution to many applications.It used the AT89C2051 chip to design a passenger car back surveillance system for the automobile company of Beijing,and introduced the hardware design and the software programming.If put down block,the system will automatically monitor video image from 0.35 metres to 5.0 metres in bus station.When the mid door opened,the system will automatically monitor the information in the car.This system has gone into production and put in use,the performance is stable,the reflection is good.
