发布时间：2018-12-12 14:29
【摘要】：20世纪80年代以来，视频监控系统发展十分迅速，系统结构不断提升，功能更加丰富，应用领域也得到了很大的扩展。根据其系统结构的不同，可将其大致分为模拟视频监控系统、模拟/数字混合监控系统和全数字网络视频监控系统三类，其中每类都包含多种实现方案。每种监控系统都有其优势和不足，因此，在不同领域中要根据具体应用需求来选择合适的监控系统类型。 本文针对高速公路监控系统架构选择的问题，以层次分析法为基础，，研究了一种针对高速公路具体需求的监控系统架构评价方法。通过研究监控系统的发展历程，总结了监控系统的主要类型，分析了各类监控系统的特点。通过分析江西省高速公路的管理结构，并以此结构为基础模拟了高速公路的典型需求；根据其需求建立了不同类型的监控系统实现方案，并针对这些监控系统在图像采集、占用带宽、传输距离、传输时延和数据存储与处理五个方面进行了量化对比；建立了基于层次分析法的评价模型，最终评价并得出了最适合高速公路需求的监控系统架构方案。
[Abstract]:Since 1980s, the video surveillance system has developed very quickly, the system structure has been improved constantly, the function is more abundant, and the application field has also been greatly expanded. According to the different system structure, it can be divided into analog video surveillance system, analog / digital hybrid monitoring system and full-digital network video surveillance system, each of which includes a variety of implementation schemes. Each monitoring system has its own advantages and disadvantages, so it is necessary to select the appropriate monitoring system type according to the specific application requirements in different fields. In this paper, aiming at the problem of the structure selection of expressway monitoring system, based on the analytic hierarchy process (AHP), a method for evaluating the architecture of expressway monitoring system is studied. By studying the development course of monitoring system, the main types of monitoring system are summarized, and the characteristics of all kinds of monitoring system are analyzed. Based on the analysis of the management structure of the expressway in Jiangxi Province, the typical demand of the expressway is simulated. According to its requirements, the realization schemes of different types of monitoring systems are established, and these monitoring systems are compared in five aspects: image acquisition, bandwidth occupation, transmission distance, transmission delay and data storage and processing. The evaluation model based on analytic hierarchy process is established, and the monitoring system architecture scheme which is most suitable for highway demand is finally evaluated.
