摘　　要：基于嵌入式系统、GPS、GPRS、软件架构设计等技术,对工程车辆监控系统进行设计研究,阐述系统的整体结构和模块功能。由于系统采用UDP通信协议进行数据传输和恶劣的施工环境等因素,通信过程中容易出现数据包丢失、车载终端断线等问题。为此,本文在制定数据通信协议交互机制中给出解决方案,提高了系统的可靠性和性能。Based on embedded system, GPS and GPRS, software architecture design of engineering technology, the paper gives the design and research for vehicle monitoring system and expounds the system＇ s overall structure and module function. Because of using the UDP communications protocols for system＇ s data transmission and poor construction environment, communication is easy to appear the issues that packet lose and car terminal disconnect. For that, the paper provides a solution in data communication protocol formulation in interactive mechanism, improving the reliability and performance scandalous.
