Description
技术领域technical field

背景技术Background technique
铁路由于其价格低廉、安全性好等特点，是我国国民经济发展的基础。近年，铁路里程不断扩大，铁路线路输送大量列车后需要对其进行大量的维修、保养等工作，而线路工人进行线路施工时，现有的安全防护设备通常是车站工作人员将该线路的施工时段设置为“天窗”期，不放行列车进入该施工区域，同时现场施工工人通过在地面设置防护设备，当有列车通过该防护设备时，向线路施工工人发送警报。这些安全防护措施都不够全面，容易导致列车闯入施工区发生列车撞人事故。Because of its low price and good safety, railway is the foundation of my country's national economic development. In recent years, the mileage of railways has continued to expand. After transporting a large number of trains, a large number of repairs and maintenance work must be carried out on the railway lines. When line workers carry out line construction, the existing safety protection equipment is usually used by station staff during the construction period of the line. Set it to the "skylight" period, and trains will not be allowed to enter the construction area. At the same time, construction workers on site will set up protective equipment on the ground, and when a train passes through the protective equipment, an alarm will be sent to the line construction workers. These safety protection measures are not comprehensive enough, and it is easy to cause the train to break into the construction area and cause a train collision accident.
通过对现有铁路施工安全防护设施的梳理，可以发现，现有的防护设施只从一个或者两个方面进行了防护，没有从车站工作人员监控，火车司机和施工工人三个方面来进行全方位的防护，且自动性不强。同时，现有的系统大多是以传统单片机为基础来进行开发，系统性能较差，特别是在实际应用时。Through sorting out the existing railway construction safety protection facilities, it can be found that the existing protection facilities only provide protection from one or two aspects, and do not provide all-round protection from the three aspects of station staff monitoring, train drivers and construction workers. protection, and the automaticity is not strong. At the same time, most of the existing systems are developed on the basis of traditional single-chip microcomputers, and the system performance is poor, especially in practical applications.

When the construction personnel complete the construction and evacuate from the construction site, send the evacuation information to the station monitoring terminal and then close the ground warning terminal, and the station staff will add the construction section to the normal train route.
本发明的工作原理为：Working principle of the present invention is:
本发明与传统铁路施工安全防护预警装置的根本区别在于，不仅设置有地面预警终端和车载预警终端，还设置有车站监控终端。其中，地面预警装置可以集成制作为一个较小的手持终端，方便携带。在地面预警装置启用时，地面预警终端与车站监控预警终端通过第二无线通信模块进行通信，同时将地面终端GPS模块测出的位置信息传输到车站监控终端，车站监控终端的显示屏上将地面终端的实时位置信息以地图形式直观的反映出来，同时第三报警模块发出警报，提醒车站工作人员线路施工情况，车站工作人员调整列车线路避开施工地点，以免工作人员忘记前方线路正在施工，误将列车放行到前方路段，造成事故。The basic difference between the present invention and the traditional railway construction safety protection early warning device is that not only the ground early warning terminal and the vehicle early warning terminal are provided, but also the station monitoring terminal is provided. Among them, the ground early warning device can be integrated into a smaller handheld terminal, which is easy to carry. When the ground early warning device is enabled, the ground early warning terminal communicates with the station monitoring and early warning terminal through the second wireless communication module, and simultaneously transmits the position information measured by the GPS module of the ground terminal to the station monitoring terminal, and the ground will be displayed on the display screen of the station monitoring terminal. The real-time location information of the terminal is reflected intuitively in the form of a map. At the same time, the third alarm module sends out an alarm to remind the station staff of the construction situation of the line. Release the train to the section ahead and cause an accident.
另外，车载预警终端通过第一无线通信模块与地面预警终端通信，当列车与施工地点的距离小于地面预警终端和车载预警终端的第一无线通信模块的传输距离时，车载预警终端与地面预警终端实现通信，同时地面预警终端和车载预警终端的报警模块都发出语音警报，车载预警终端的第一报警模块发出预设的比如“前方正在施工，请立即制动”的语音，地面预警终端的第二报警模块发出预设的比如“列车到来，请立即趋避的语音。In addition, the vehicle-mounted early warning terminal communicates with the ground early warning terminal through the first wireless communication module. Realize communication, and at the same time, the alarm modules of the ground early warning terminal and the vehicle early warning terminal both send out voice alarms. The second alarm module sends preset voices such as "the train is coming, please avoid it immediately.
这样从火车司机、施工人员和车站工作人员三个方面对铁路线路施工人员进行安全防护，可以极大的提高铁路线路施工人员的安全性。In this way, the safety protection of railway line construction personnel from three aspects of train drivers, construction personnel and station staff can greatly improve the safety of railway line construction personnel.
且当施工人员无法及时撤离且列车司机未及时停车时，列车在通过设置在铁路上的点式电磁感应器的位置处时，列车制动装置可以自动制动列车停车，增强了铁路施工的安全性。And when the construction workers cannot evacuate in time and the train driver does not stop in time, when the train passes the position of the point electromagnetic sensor set on the railway, the train braking device can automatically brake the train to stop, which enhances the safety of railway construction sex.
同时，系统采用性能更好的嵌入式ARM模块进行开发，系统的稳定性和有效性更好。此外，系统采用的模块均为低功耗，性能优良的模块，因此系统简单、便捷，成本低廉，可实施性极强。At the same time, the system is developed with an embedded ARM module with better performance, and the stability and effectiveness of the system are better. In addition, the modules used in the system are low-power modules with excellent performance, so the system is simple, convenient, low-cost, and highly implementable.
本领域的普通技术人员可以根据本发明公开的这些技术启示做出各种不脱离本发明实质的其它各种具体变形和组合，这些变形和组合仍然在本发明的保护范围内。Those skilled in the art can make various other specific modifications and combinations based on the technical revelations disclosed in the present invention without departing from the essence of the present invention, and these modifications and combinations are still within the protection scope of the present invention.
