【摘要】：随着铁路事业的不断发展,防止发生路外伤亡成为目前一项重要工作。铁路防路伤报警多数是在隧道,桥梁,以及路伤重点区域设置事故按钮,表示灯和警笛信号灯和警笛,采用人工判断,并鸣响报警设备,通知行人远离铁路。由于涉及繁琐的人为操作,有可能形成一定的误报、延报和漏报情况,造成严重的后果。为了提高铁路系统的安全性,需要设计一个自动精准的防路伤移动报警系统.通过铁路防路伤警报系统的建设,能够对行驶中的列车进行即时监控,当列车一定距离接近路上重点区域时由系统自动发出警报信号,通知该地段的行人远离铁路,保障列车的安全运营。本文在对现有的报警系统分析的基础上,针对系统移动性、可靠性以及低功耗等特殊需求,设计并实现了以公共移动通信网作为基本通信通道,结合GPS定位、GPRS数据传输、低功耗设计等一系列技术的防路伤自动报警系统。在硬件设计方面,采用模块化的设计思想,主要由火车端的发射模块、道口的接收模块和服务器三部分组成,通过对供电电源电路、控制电路以及通信电路等系统硬件电路模块上不可靠性以及高功耗性的因素进行分析,从而提出并实现具有高可靠性和低功耗性硬件电路设计,并对硬件电路设计的可靠性与低功耗性进行分析与验证；在软件设计方面,通过对系统中各模块工作模式的性能分析,采用实时休眠与及时唤醒方式的系统工作模式,并以TCP/IP协议为基础,在低功耗的嵌入式处理机上设计并实现了一个轻量级多路通信协议,从软件设计方面巩固系统的可靠性和低功耗性,为实现系统的设计目标奠定基础。实际应用表明本文设计的铁路防路伤自动移动报警系统在准确性、可靠性、低功耗、功能等方面能完全适应目前铁路系统的防路伤安全要求,达到了预期设计效果和产品级成熟度,现已投入实际应用和小批量生产。
[Abstract]:With the continuous development of railway industry, it is an important task to prevent off-road casualties. The railway road injury alarm is mostly set in the tunnel, bridge, and the key area of road injury with accident buttons, indicating lights and sirens, signal lights and sirens, using manual judgment, and sounding alarm equipment to inform pedestrians to stay away from the railway. Because of the complicated human operation, it is possible to form a certain misinformation, delay and omission of the situation, resulting in serious consequences. In order to improve the safety of railway system, it is necessary to design an automatic and accurate mobile alarm system for road injury prevention. Through the construction of the railway road injury alarm system, the running train can be monitored instantly. When the train is close to the key area of the road, the system automatically sends out an alarm signal and informs the pedestrian in the section to stay away from the railway. Ensure the safe operation of the train. Based on the analysis of the existing alarm system, aiming at the special requirements of system mobility, reliability and low power consumption, this paper designs and implements the public mobile communication network as the basic communication channel, combined with GPS positioning and data transmission. Low-power design and a series of technologies for automatic road injury alarm system. In the aspect of hardware design, the modular design idea is adopted, which is mainly composed of three parts: the transmitter module at the train end, the receiving module at the crossing and the server. Through the power supply circuit, The factors of unreliability and high power consumption in the hardware circuit module of control circuit and communication circuit are analyzed, and the design of hardware circuit with high reliability and low power consumption is put forward and realized. The reliability and low power consumption of the hardware circuit design are analyzed and verified. In the software design, through the performance analysis of each module in the system, the real-time dormancy and timely wake-up mode are adopted. Based on the TCP/IP protocol, a lightweight multiplex communication protocol is designed and implemented on a low power embedded processor, which consolidates the reliability and low power consumption of the system from the aspect of software design, and lays a foundation for the realization of the system design goal. The practical application shows that the automatic moving alarm system designed in this paper can fully meet the safety requirements of railway system in the aspects of accuracy, reliability, low power consumption, function and so on. Achieved the expected design effect and product-level maturity, has been put into practical application and small-batch production.
