摘　　要：本文基于城市交通物联网及远程控制的发展趋势,提出一个设备无关的、可靠的、面向连接的传输控制协议,使各种交通设备的传输数据和控制命令能够以统一的数据格式进行表示和传输,并通过Internet来进行远程感知和控制。设计了设备和服务器间交互报文的数据格式,结合通信协议的原子性、次序性、实时性和容错性,实现了连接建立、数据传输、状态维护、丢包检测和重传机制、拥塞控制等关键技术。通过仿真和实验分析了可行性及传输性能。This paper introduces a hardware independent, reliable and connection oriented transportation control protocol for urban traffic surveillance based on the trend of urban traffic cyber-physieal systern and remote control. We uniform the structure of the traffic information data and the manipulation instructions of all traffic devices, and implement remote sensing and control via the Internet. We design the data format of mutual communication packet between lbe client and the server, and on the basis of the properties of data communication protocol： atomicity, ordering, real-timencess and fauh ruler ance, and implement the pivotal technical issues including connection establishment, link status maintenance, data transmission, packet loss detection and relransmitting, and congestion controlling. The feasibility and performance are analyzed through simulation and experiments.
