Current systems for monitoring "critical vehicles" usually have the problems such as uncultured management flow, lack of technical competitiveness, and low information sharing rate. However, the development of Internet of things provides new means to advance such a system. In this paper, the business needs of such a system are first analyzed. Then, a framework based on Internet of things is proposed and each of its components is presented in detail. The key technologies used, including vehicle identification technology, network data exchange and communication technology, data management and analysis technology, data authentication technology and network security and usability technology, are also presented.%当前重点车辆监控平台存在管理模式落后、技术手段缺乏、信息共享率低等问题.物联网技术的发展,可以为重点车辆监控与管理带来新的思路和手段.分析了当前重点车辆监控的业务需求及存在问题,然后提出基于物联网的重点车辆监控平台总体框架,对该框架的各个层次进行了详细分析.结合该平台总体框架,讨论了监控车辆标识技术、网络数据交换与通信技术、海量监控数据管理与分析技术、业务数据真实性辨析技术和网络安全性与可用性技术等关键技术.
