Metro Area Safety Monitoring System Design Based on Internet of Things

为更好的保障地铁行车安全,及地铁站内环境安全和对灾害事故的预防,需要对地铁区域安全监控进行设计;当前采用的方法是利用传感器获取的监控信号经过现场中心接口传送至监控中心,在监控中心完成对数据信号的采集分析,通过网络与数据中心进行数据通信,在监控数据中心中完成对数据参数的处理以及预警和报警等功能,并对地铁进行实时监控;虽然该方法成本较低,但存在监控数据过程中产生数据丢失问题;为此,提出一种基于物联网的地铁区域监控安全监控系统设计方法;该方法首先对地铁区域安全硬件系统进行设计,硬件系统主要由感知层模块以及网络层模块和应用层模块三部分构成,利用分段曲线算法对监控到的数据进行传输,以传输的数据为基础,结合粒子滤波对监控数据进行处理,以数据处理结果完成对地铁区域安全监控系统设计;实验结果表明,所提方法能有效地提高地铁行车的安全性,保证乘车安全,为地铁安全建设发展提供依据。

In order to ensure the safety of subway operation and the environmental safety of the subway station and the prevention of the disaster,it is necessary to design the safety monitoring of the subway.The current method is used after the scene monitoring center interface transmitted to the monitoring center by using sensor signal acquisition,analysis on data signal acquisition in the monitoring center,data communication by network and data center,the completion of the data processing and early warning and alarm functions in data center monitoring,real-time monitoring of subway.Although the cost of this method is low,there is a problem of data loss in the process of monitoring data.For this reason,this paper presents a design method of metro area monitoring and control system based on Internet of things.This method first carries on the design to the subway security hardware system,the hardware system is composed of three parts:sensing layer module and network layer module and application layer module.transmission by using the piecewise curve algorithm to monitor the data to transmit data as the basis,combined with the particle filter on the monitoring data,complete the design of the metro area safety monitoring system in data processing.The experimental results show that the proposed method can effectively improve the safety of subway driving and ensure the safety of the vehicle.
