基于TMS320DM355的出租车安全监控系统设计

Design of Taxi Safety Monitoring System Based on TMS320DM355

TMS320DM355是TI公司的一款高性能,低价格、针对于便携性消费电子应用而设计的一款处理器。本设计是以该处理器为平台,采用CMOS高清图像传感器,结合GPS定位技术、CDMA无线通讯技术,实现车内图像、声音及车辆位置信息的采集并无线发送的车辆安全监控系统。本系统通过CMOS图像传感器采集车内图像,GPS模块采集车辆位置信息,高质量音频ADC采集车内语音信息,并实现JPEG及G.711压缩,以网络数据包的形式通过无线网络发送至监控中心,以进行车辆信息的采集,管理及控制。本文主要介绍了整个系统的硬件结构及软件的架构方法。

TMS320DM355 is one of TI Inc high performance, low price MCU targeting at consumer electronics application.This design is build on the platform of this MCU, using CMOS high definition image sensor, GPS location technology, CDMA wireless communication technology, archiving the collection and transmission of picture, sound and taxi location.CMOS image sensor is used to capture the image of inside situation.GPS module is used to locate the taxi.High quality ADC is used to collect the sound information.All the information is processed and packaged, and transmitted to Surveillance Center by wireless network.So the Surveillance Center can supervise all these taxies.The hardware and software architectures are presented in this article.
