Crowded Area Web Monitoring System Design Based on DHCP Netuwork Protocol

摘要:

为了降低踩踏事件发生频率,设计并实现了基于DHCP 网络协议的人流密度Web监控系统,该系统通过DHCP网络协议将现场的人员图像实时传输给服务器,塑造了认证服务器和检测服务器,采用面向服务的架构以及依据角色访问控制相融合的技术管理监控人员的权限,监控人员依据不同的权限进入Web监控平台,Web监控平台实时的通过网络分析、控制、监控终端等模型监控和管理人员流动图像数据,并使用依据人员像素密度阀值的自主报警模块对人流密度进行报警,最终减少了人员踩踏事件的发生;采用该系统对某车站入口处监测点进行应用实验,在Matlab7.0平台上完成测试,实验时Web通信划分成外部干扰能够忽略和外部干扰不可忽略两种情况;仿真时间定为3 000 s,实验结果表明利用文章系统对人流密集区域监控的准确率达到97%左右,误差平均在3%左右,而传统设计误差在20%以上,表明文章系统的鲁棒性更强,更适合推广应用。

Abstract:

In order to reduce the stampede occurred frequency, designed and implemented based on DHCP network Protocol web traffic density monitoring system, the system through the DHCP network Protocol will be the scene of the personnel image real-time transmission to the server, shaped the authentication server and test server, using a service oriented architecture and the technology of blending based on role access control permissions management monitoring, monitoring personnel according to different permissions to enter web monitoring platform, web monitoring platform in real time through the network analysis, control and monitoring terminal monitoring and management flow image data model, and use the pixel density threshold based on personnel independent alarm module to call the police, traffic density eventually reduce the personnel stampede occurred. Adopts the system of application experiments, at the entrance to the station monitoring stations on Matlab7.0 platform to complete the test, the experiment of web communication divided into external interference can be ignored and the external disturbance should not be neglected two cases. Simulation time was 3 000 seconds, the experimental results show that the system presented in this paper to the crowded area monitoring accuracy of about 97%, the average error is around 3%, while traditional design error is above 20%, showed in this paper, the robustness of system is stronger, more suitable for popularization and application.
