[0002] Railway stations refer to the demarcation points for handling train passing, arrival and departure, train technical operations, and passenger and freight services; line stations refer to the non-wiring demarcation points on railway sections that connect to branch lines, and are the places where multiple lines intersect; relay stations refer to the locations of signal relay equipment set up between two stations (or line stations) when the track circuit control cable exceeds a certain length to ensure reliable operation of the track circuit. Signal equipment such as CTC (railway dispatching centralized system), train control, interlocking, and centralized signal monitoring are generally set up at stations and line stations, and signal equipment such as train control and centralized signal monitoring are generally set up at relay stations.

[0003] The configuration of signal system equipment at stations (including line stations) and relay stations along the railway is related to the specific design of the line and station yard. The hardware and software / data configurations are all customized developments. The execution and presentation layers of interlocking and train control equipment are equipped with a large number of relay interface circuits, or train control and interlocking integration (TIS) equipment is used. Figure 1 The figure shows the connection diagram of existing stations, relay stations and central signal equipment. However, the hardware and software of the signal systems of various stations are also quite different. Once a serious disaster (such as fire, flood, etc.) occurs to the signal equipment in these places, it is difficult to restore the normal operation of the railway in a short time, which has a great impact on the railway transportation order. However, there is still a lack of effective equipment. Summary of the invention

[0004] The present invention aims to solve the technical problem of how to coordinate indoor signal equipment of stations and / or relay stations along the railway with other signal equipment to quickly restore the railway to a normal operating state in the event of a disaster. The configurable emergency signal system provided by the present invention includes: a dispatching center, a monitoring center, an emergency center, a station and a relay station;

[0005] The emergency center includes several security computers and servers, wherein the security computer is installed with the station TIS (train control and interlocking integration) equipment, which is connected to the target controller of the station and / or relay station via the signal safety data network; the server is installed with the CTC station machine and signal centralized monitoring station machine software of the station and / or relay station, and is connected to the CTC central equipment of the dispatching center and the monitoring central equipment of the monitoring center via the dispatching centralized data network and the centralized monitoring data network respectively.

[0006] The software of the emergency center adopts the software used in the station and / or relay station.

[0007] The TIS equipment CTC station and signal centralized monitoring station of the emergency center are both pre-debugged hardware and software and can be put into use at any time.

[0008] The communication connection between the TIS equipment, CTC station and signal centralized monitoring station of the emergency center and other signal equipment maintains the existing mode.

[0009] The TIS equipment of the emergency center exchanges information with the TIS equipment of other stations, central RBC (Radio Block Center) equipment, and TSRS (Temporary Speed ​​Limit Server) equipment via the signal security data network, and the software and hardware structure and protocol remain unchanged.

[0010] The safety computer and server of the emergency center are deployed in the same computer in the form of modules, or independently deployed in different computers.

[0011] The equipment or modules of the emergency center are configurable, and are determined according to the equipment or functional modules required by one or more stations and / or relay stations along the railway.

[0012] The target controller includes OC-turnout, OC-signal and the like.

[0013] The emergency method based on the configurable emergency signal system provided by the present invention comprises the following steps performed in sequence:

[0014] 1) When no disaster occurs, the emergency center of the emergency signal system is in the original connection state, and all equipment in the emergency center is in the hot standby working state. On the premise of not affecting the work of the station and / or relay station equipment, the station and / or relay station equipment status information is collected, and no control command is output;

[0015] 2) When a disaster occurs to the indoor equipment of a station and / or relay station, a connection is established between the new target controller of the station and / or relay station and the trackside equipment.

[0017] The emergency method of the configurable emergency signal system also includes: after the TIS equipment, CTC station machine, and signal centralized monitoring station machine equipment of the station and / or relay station are repaired, switching back to the original connection state between the station and / or relay station and the TIS equipment, CTC station machine, and signal centralized monitoring station machine equipment of the station and / or relay station, and the connection state of the emergency center of the emergency signal system is restored to the original connection state of the emergency center in preparation for other disasters.

[0018] The advantages and positive effects of the present invention are as follows: the present invention establishes an emergency signal system, adopts TIS equipment based on stations and relay stations, and basically realizes standardization of the external interface of the system.

[0025] First of all, it should be noted that the specific structure, features and advantages of the present invention will be specifically described below by way of example, but all descriptions are only for illustration and should not be understood as limiting the present invention in any way. In addition, any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the drawings, can still be combined or deleted between these technical features (or their equivalents) to obtain more other embodiments of the present invention that may not be directly mentioned herein.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0027] In order to better understand the content of the present invention, a brief introduction to the prior art in this field is now given.

[0028] Domestic railway signal systems are generally composed of ground equipment and on-board equipment. The ground equipment includes dispatching and command equipment, such as centralized dispatching CTC equipment, computer interlocking equipment, train control equipment, centralized signal monitoring equipment, etc. The train control equipment is configured differently according to different train control levels. For example, the ground equipment of the CTCS-2 train control system mainly includes the temporary speed limit server (TSRS), train control center (TCC), transponder and ground electronic unit (LEU), etc. The CTCS-3 level train control ground equipment adds a wireless block center (RBC) on the basis of the CTCS-2 level train control equipment. Compared with the CTCS-3 level, the CTCS-N level train control system does not need to have track circuits in the section and relies on active positioning of the train, which has slight differences in equipment configuration.

[0029] The integrated train control and interlocking (TIS) equipment has all the functions of the train control center and computer interlocking. It is a signaling device that uses safety computer technology and electronic control technology as the main means to realize functions such as station interlocking, section blocking and active balise control. It is a safety-related equipment.

[0030] CTC equipment commands and manages trains and shunting operations within the jurisdiction section, and realizes centralized dispatching command and control through interlocking, train control and blocking equipment. Generally, CTC central equipment is set up in the dispatching office (dispatching center), and CTC station equipment is set up in the station. The temporary speed limit server (TSRS) realizes centralized and unified management of temporary speed limits and is a safety-related equipment. The wireless block center (RBC) is the ground core equipment of the CTCS-3 level train control system. It has multiple functions such as driving permit calculation and is a safety-related equipment. The signal centralized monitoring equipment monitors the status of related signal equipment to assist maintenance operations, and is divided into central equipment and station equipment. The present invention does not involve the innovative content of TSRS equipment and RBC equipment, and its functions are introduced only for the integrity of the signal system.

[0031] The safety-related equipment TIS, TSRS and RBC in the signal system exchange information through the signal safety data network. The CTC center and station equipment exchange information through the dispatching centralized data network. 5 The signal centralized monitoring center equipment and station equipment exchange information through the monitoring data network.

[0032] The target controller (OC) is a safety control device that can directly control the trackside signal equipment. It is mainly composed of a communication control module and several electronic execution modules. It can communicate with the safety host for safety-related purposes. It is dedicated to centralized (terminal) real-time control and status monitoring of various trackside signal equipment.

[0033] The target controller can be located indoors (with the advantage of easy maintenance) or trackside (with the advantage of saving cables) as required, and its function remains unchanged.

[0034] Railway stations refer to the demarcation points for handling train passing, arrival and departure, train technical operations, and passenger and freight services. Generally, stations are equipped with turnouts, but in special cases, there are also non-wired stations without turnouts; line stations refer to the non-wired demarcation points where branch lines are connected on railway sections. They are the places where multiple lines intersect, but generally there are no tracks for trains to stop. The main purpose is to allow trains to cross lines from one line to another; relay stations refer to the location of signal relay equipment set up between two stations (or line stations) when the track circuit control cable exceeds a certain length to ensure the reliable operation of the track circuit. There are no turnouts at this location. Signal equipment such as CTC, train control, interlocking, and centralized signal monitoring are generally set up in stations and line stations, and signal equipment such as train control and centralized signal monitoring are generally set up in relay stations.

[0035] Example 1

[0036] 0 Figure 2 As shown, the configurable emergency signal system provided in this embodiment includes: a dispatch center, a monitoring center, an emergency center, a station and a relay station;

[0037] The emergency center includes several security computers and servers, wherein the security computer is installed with the station TIS (train control and interlocking integration) equipment, which is connected to the target controller of the station and / or relay station via the signal safety data network; the server is installed with the CTC station machine and signal centralized monitoring station machine software of the station and / or relay station, and is connected to the CTC central equipment of the dispatching center and the monitoring central equipment of the monitoring center via the dispatching centralized data network and the centralized monitoring data network respectively.

[0038] In this embodiment, the emergency center hardware equipment adopts a universal and simplified configuration, and the software adopts the software used in each station so as to be put into use quickly and achieve the best technical economy and cost performance.

[0039] In this embodiment, the TIS equipment, CTC station, and signal centralized monitoring station of the emergency center are all pre-debugged hardware and software and can be put into use at any time.

[0040] In this embodiment, the communication connection between the TIS equipment, CTC station, centralized signal monitoring station and other signal equipment of the emergency center maintains the existing mode.

[0041] In this embodiment, the TIS equipment of the emergency center exchanges information with TIS equipment of other stations, central RBC equipment, and TSRS equipment via a signal security data network, and the software and hardware structures and protocols remain unchanged.

[0042] In this embodiment, the security computer and server of the emergency center do not represent specific devices, but are aliases for devices in the resource pool. The two can be deployed in the same computer through module combination or independently in different computers.

[0043] In this embodiment, the equipment or modules of the emergency center are configurable and can be configured as any required equipment or functional modules of one or more stations and / or relay stations along the railway as needed to play the role of resource pool and minimize the equipment configuration of the emergency center.

[0044] Example 2

[0045] like Figure 2-5 As shown, the emergency method provided by this embodiment based on the configurable emergency signal system of embodiment 1 includes the following steps performed in sequence:

[0046] 1) When no disaster occurs, the emergency center of the emergency signal system is in the original connection state, and all equipment in the emergency center is in the hot standby working state. On the premise of not affecting the work of the station and / or relay station equipment, the station and / or relay station equipment status information is collected, and no control command is output;

[0047] 2) When a disaster occurs to the indoor equipment of a station and / or relay station, assuming that the trackside equipment is still usable at this time, based on the characteristics that the station-level target controllers (OC-turnouts, OC-signals, etc.) are all non-customized standard equipment, a new target controller can be quickly connected to the trackside equipment. At this time, the TIS equipment of the emergency center is connected to the new target controller of the station and / or relay station via the signal safety data network; the CTC station machine and signal centralized monitoring station machine software of the emergency center are connected to the CTC center equipment and the monitoring center equipment via the dispatching centralized data network and the centralized monitoring data network respectively;

[0048] 3) Then, based on the TIS equipment, CTC station machine, and signal centralized monitoring station machine of the emergency center, the emergency center and the trackside equipment are coordinated to realize the central control function of the emergency center over the affected stations and / or relay stations. The station-level operation display function will be gradually restored later.

[0049] In this embodiment, the security computer of the emergency center has the ability to take over the integrated train control and interlocking (TIS) logical subsystem of any one or more stations under its jurisdiction, and its software and hardware configuration has been debugged in advance and can be put into use quickly; the server of the emergency center has the ability to take over the CTC station and signal centralized monitoring station of any one or more stations and / or relay stations under its jurisdiction, and its software and hardware configuration has been debugged in advance and can be put into use quickly; the security computer and server functions can be further integrated in the future to maximize the role of the resource pool.

[0050] After a disaster occurs at a station, the station-level target controller equipment is quickly built in combination with the original architecture of the station's target controller (located indoors or on the trackside), and the connection and debugging with the trackside equipment are realized. Each target controller is connected to the new TIS equipment of the emergency center through the signal safety data network. The new TIS equipment controls the trackside equipment of the station. The new TIS equipment is connected to the new station CTC station machine of the emergency center, thereby realizing two-way communication with the CTC center equipment. The new TIS equipment is connected to the new signal centralized monitoring station machine of the emergency center, thereby realizing two-way communication with the monitoring center equipment.

[0051] In this embodiment, the TIS equipment of the emergency center exchanges information with the TIS equipment of other stations, the central RBC equipment, and the TSRS equipment via the signal security data network. The hardware and software structures and protocols remain unchanged. After the TIS equipment of the affected station fails, the emergency center can switch seamlessly, and the control logic of the trackside equipment that has a direct impact on transportation remains unchanged, and the transportation order can be quickly restored.

[0052] In this embodiment, the communication connections between the CTC station machine, signal centralized monitoring station machine of the emergency center and the CTC central equipment and monitoring center equipment of the dispatching center are maintained in the existing mode. After a station disaster occurs, the emergency center quickly restores the connection with it, and the dispatching center can still remotely dispatch and command the equipment on the entire line, and the monitoring center can still monitor the operation of the equipment on the entire line.

[0053] In this embodiment, while the emergency center maintains the line operation, it promptly repairs the station TIS equipment, CTC station machine, signal centralized monitoring station machine and other equipment. After they are completely repaired, they switch back to the original connection state between the station and each device, and the emergency center connection state is restored to the original connection state in preparation for other disasters.

[0054] It is worth noting that the embodiments of the present invention are applicable to various types of railways. When used in conventional railways, no equipment related to the train control system is required, and the train control interlocking integrated structure can still be used. The train control function is simplified to control the track circuit code, control the section running direction and other functions. No RBC, TSRS and other equipment are provided. When used in a CTCS-2 level train control system, RBC may not be provided; when used in a CTCS-3 or CTCS-N level train control system, all the above equipment are provided.

[0055] The present invention establishes an emergency signal system, adopts integrated train control and interlocking equipment (TIS) at stations and relay stations, and basically realizes standardization of the external interface of the system. Through the hardware and software configured by the emergency center that meet the control requirements of each station, logical control of stations and / or relay stations affected by disasters is realized, and existing technologies and equipment can be fully utilized to quickly restore the normal operation of the railway signal system, thereby improving the efficiency of emergency disposal under the premise of ensuring safety.

[0056] The above embodiments describe the present invention in detail, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
