Description
技术领域technical field
本发明涉及轨道交通安全技术领域，尤其涉及一种高速铁路地震监测预警信号接口单元。The invention relates to the technical field of rail transit safety, in particular to a high-speed railway earthquake monitoring and early warning signal interface unit.
背景技术Background technique
目前，国外地震紧急处置系统在列车接到地震报警后，对列车施行控制的模式(即列车如何制动)主要有两种：一种是以法国地中海线为代表的列控系统控制模式，即接到报警时，由列控系统发出控制列车运行的信号，自动控制列车停止运行；另一种是以日本新干线为代表的牵引供电系统控制模式，即接到报警时，牵引变电所停止向接触网供电，列车车载装置检出接触网断电后立即自动采取紧急制动措施。在高速铁路较为发达的日本、法国，针对铁路运输均建立了相应的地震紧急处置系统。在地震发生后，当破坏性地震波尚未来袭的数秒至数十秒之前地震预警系统发出报警信号，地震紧急处置系统采取相应措施，使高速列车尽快减速或停车，以防止或减轻地震灾害对铁路运输安全带来的危害，避免重大的人员伤亡和经济损失。At present, foreign earthquake emergency response systems mainly have two modes of controlling the train (that is, how the train brakes) after the train receives an earthquake alarm: one is the control mode of the train control system represented by the French Mediterranean Line, namely When an alarm is received, the train control system sends a signal to control the operation of the train, and automatically controls the train to stop running; the other is the control mode of the traction power supply system represented by the Japanese Shinkansen, that is, when the alarm is received, the traction substation stops Power is supplied to the catenary, and the on-board device of the train detects that the catenary is powered off and automatically takes emergency braking measures immediately. In Japan and France, where high-speed railways are more developed, corresponding earthquake emergency response systems have been established for railway transportation. After the earthquake, when the earthquake warning system sends out an alarm signal from seconds to tens of seconds before the destructive earthquake wave hits, the earthquake emergency response system takes corresponding measures to slow down or stop the high-speed train as soon as possible, so as to prevent or reduce the impact of the earthquake disaster on the railway. Hazards caused by transportation safety, to avoid major casualties and economic losses.
我国是一个地震灾害严重的国家，地震灾害对高速列车运行安全的影响不容忽视。由于我国高速铁路地震预警技术与国外相比还不成熟，暂未形成完善的标准体系，在设备制造、预警方式、地震紧急处置技术等方面与国际上还存在一定的差距。研究适合我国高速铁路现状的、可行的地震紧急处置技术显得异常迫切。my country is a country with severe earthquake disasters, and the impact of earthquake disasters on the safety of high-speed train operation cannot be ignored.

There is still a certain gap between China and the world in terms of equipment manufacturing, early warning methods, and earthquake emergency response technology. It is extremely urgent to study feasible earthquake emergency disposal technology suitable for the current situation of my country's high-speed railway.

Exemplarily, the communication network can be accessed using a standard RJ-45.
如图2所示，所述处理单元包含处理单元A与处理单元B。所述处理单元A与处理单元B均可以通过通信网络与相邻台站及铁路局中心系统进行通信，一方面，可以接收相邻台站发送的地震P波预警和/或阈值报警信息并判断处置级别，再根据处置级别向控制单元输出地震报警状态信号；也可以接收铁路局中心系统发送的紧急处置指令信息并根据警报级别向控制单元输出地震报警状态信号；另一方面，还可以接收铁路局中心系统发送的误报解除和恢复指令信息，并依次通过控制单元与继电器和防雷单元向信号系统输出恢复正常状态信号。As shown in FIG. 2 , the processing unit includes a processing unit A and a processing unit B.

所述控制单元包括：输入输出接口模块、逻辑处理模块与24V电源模块。其中：The control unit includes: an input and output interface module, a logic processing module and a 24V power supply module. in:
输入输出接口模块，用于数字信号输出和隔离数字信号输入；其可以通过37芯D型电缆与逻辑处理模块连接。The input and output interface module is used for digital signal output and isolated digital signal input; it can be connected with the logic processing module through a 37-core D-type cable.
逻辑处理模块，用于当处理单元为冗余结构时仲裁处理单元输出的地震报警状态信号，并结合人工控制的隔离开关信号，输出相应的报警控制命令。The logic processing module is used to arbitrate the earthquake alarm status signal output by the processing unit when the processing unit is in a redundant structure, and output the corresponding alarm control command in combination with the manually controlled isolating switch signal.
本发明实施例中，逻辑处理模块将输入输出接口模块输出的数字信号做了一定的逻辑运算处理并转换成控制继电器的电压。输入输出接口模块的隔离数字信号输入是指电路连接上经过了隔离元件的保护，减少外部电路对内部元件的干扰。人工控制的隔离开关信号是整个信号接口单元的一个人工开关所产生的信号，其意义是控制信号接口单元工作在隔离状态或非隔离状态。In the embodiment of the present invention, the logic processing module performs certain logical operation processing on the digital signal output by the input and output interface module and converts it into a voltage for controlling the relay. The isolated digital signal input of the input and output interface module means that the circuit connection has been protected by isolation components, reducing the interference of external circuits on internal components. The artificially controlled isolating switch signal is a signal generated by a manual switch of the entire signal interface unit, and its meaning is to control the signal interface unit to work in an isolated state or a non-isolated state.
逻辑处理模块具体的工作过程如下：当处理单元为包含处理单元A与处理单元B的冗余结构时，若人工开启隔离开关，则无论是否接收到处理单元A与处理单元B输出的地震报警状态信号，均不向继电器和防雷单元输出报警控制命令；若人工关闭隔离开关，则接收到处理单元A或处理单元B输出的地震报警状态信号时，向继电器和防雷单元输出报警控制命令，以保障当有一路出现故障时系统依然可以正常工作。The specific working process of the logic processing module is as follows: When the processing unit is a redundant structure including processing unit A and processing unit B, if the isolation switch is manually turned on, no matter whether the earthquake alarm status output by processing unit A and processing unit B is received or not Signals do not output alarm control commands to relays and lightning protection units; if the isolating switch is manually closed, when the earthquake alarm status signal output by processing unit A or processing unit B is received, alarm control commands are output to relays and lightning protection units, In order to ensure that the system can still work normally when there is a failure along the way.
另外，本发明实施例中，当处理单元A与处理单元B输出的信号为无效信号(即，非地震报警状态信号或恢复正常状态信号均为有效信号)时，发出系统故障报警信息；并且，当处理单元A与处理单元B均输出恢复正常状态信号时，输出相应的恢复正常控制命令。这两种信号的仲裁过程与前述地震报警状态信号的仲裁过程类似，不再赘述。In addition, in the embodiment of the present invention, when the signals output by the processing unit A and the processing unit B are invalid signals (that is, the non-earthquake alarm state signal or the return to normal state signal are both valid signals), a system failure alarm message is sent; and, When both the processing unit A and the processing unit B output the normal state recovery signal, a corresponding normal recovery control command is output. The arbitration process of these two signals is similar to the arbitration process of the aforementioned earthquake alarm status signal, and will not be repeated here.
24V电源模块，其为二乘二的冗余结构，用于为信号系统的地震继电器供电。电源的设计满足系统设备要求，无论系统中24V电源组的任意一个出现故障，都不会影响系统的正常工作，从而提高了高速铁路地震监测预警信号接口单元的可靠性。The 24V power supply module, which is a two-by-two redundant structure, is used to supply power to the seismic relay of the signaling system. The design of the power supply meets the requirements of the system equipment.

地震预警继电器模块，其包含两个地震预警继电器(其型号可以为JWXC-1700)，用于通过接收到的报警控制命令来改变地震预警继电器的状态，从而向信号系统传送地震报警信号；Earthquake early warning relay module, it comprises two earthquake early warning relays (its model can be JWXC-1700), is used for changing the state of earthquake early warning relay by the alarm control order that receives, thereby transmits earthquake warning signal to signal system;
旁路开关模块，用于支持高速铁路地震监测预警信号接口单元内部设备的更换与检修，并能保证在设备更换与检修期间不会影响信号系统的地震继电器误动作。The bypass switch module is used to support the replacement and maintenance of the internal equipment of the high-speed railway earthquake monitoring and early warning signal interface unit, and can ensure that the earthquake relay will not affect the malfunction of the signal system during the equipment replacement and maintenance.
防雷模块，用于通过设置电源浪涌保护器对电源供电线路进行雷电防护，有效地保护电源供电线路的安全。The lightning protection module is used to protect the power supply line from lightning by setting a power surge protector, so as to effectively protect the safety of the power supply line.
电源单元为UPS电源(不间断电源)，用于给处理单元及控制单元供电；电源零层接入从供电配电盘(箱)引入的双路单相交流220V电源，电源零层同时设置有空气开关、220V电源防雷单元和电源插座。The power supply unit is UPS power supply (uninterruptible power supply), which is used to supply power to the processing unit and control unit; the zero floor of the power supply is connected to the dual-channel single-phase AC 220V power supply introduced from the power supply distribution board (box), and the zero floor of the power supply is also equipped with an air switch , 220V power supply lightning protection unit and power socket.
本发明实施例中，高速铁路地震监测预警信号接口单元通过冗余技术保障系统的可靠性和安全性。系统中的冗余主要包括电源冗余设计和处理单元的冗余设计，通过配置多余的同等功能的部件，并通过一定的冗余逻辑使它们协调同步运行，降低了系统的失效率，提高了整个系统的平均故障间隔时间；同时，通过设置旁路开关保障系统的可靠性和可维护性。便于信号接口单元设备的更换与检修，并能保证在设备更换与检修期间不会影响信号系统的地震继电器误动作。In the embodiment of the present invention, the high-speed railway earthquake monitoring and early warning signal interface unit guarantees the reliability and safety of the system through redundancy technology. The redundancy in the system mainly includes the redundant design of the power supply and the redundant design of the processing unit.
