本发明涉及一种城市轨道交通信号系统，尤其是涉及一种用于城市轨道交通信号系统的控制中心主备系统。The invention relates to an urban rail traffic signal system, in particular to a control center main and backup system for the urban rail traffic signal system.
背景技术Background technique
城市轨道交通信号系统设备主要分布在控制中心、车站/车辆段/停车场、线路轨道旁、列车上。在控制中心的设备主要有ATS子系统、DCS子系统、MSS子系统。一般ATS关键设备如ATS应用服务器、ATS数据库服务器、DCS关键设备如信号路由器、车地无线通信数据处理服务器(如LTE核心网处理器)等重要设备布署在控制中心设备机房。当控制中心出现异常情况下，如控制中心所在位置出现了火灾、洪水、超过一定时间的断电等，导致控制中心设备无法工作，此时DCS系统、ATS系统关键设备无法正常工作，会影响城市轨道交通正常运营，特别是对于全自动无人驾驶线路，控制中心所在位置由于突发情况出现断电，将导致DCS信号路由器等无法工作，无法实现车地无线通信，轨旁ATC计算的移动授权无法发送到车载ATC，从而会导致列车紧急制动。控制中心断电，也会导致ATS应用服务器、ATS数据库服务器等无法正常工作，无法给列车发送列车运行计划。特别对于全自动无人驾驶线路，出现此情况由于列车上没有司机，将会影响列车无法继续运营，影响乘客出行。The urban rail transit signal system equipment is mainly distributed in the control center, station/depot/parking lot, beside the line track, and on the train. The equipment in the control center mainly includes ATS subsystem, DCS subsystem and MSS subsystem. General ATS key equipment such as ATS application server, ATS database server, DCS key equipment such as signal router, vehicle-ground wireless communication data processing server (such as LTE core network processor) and other important equipment are deployed in the equipment room of the control center. When there is an abnormal situation in the control center, such as fire, flood, power outage over a certain period of time, etc. at the location of the control center, the equipment of the control center cannot work. At this time, the key equipment of the DCS system and ATS system cannot work normally, which will affect the city. The normal operation of rail transit, especially for fully automatic unmanned lines, the location of the control center is powered off due to unexpected situations, which will cause the DCS signal router to fail to work, and it is impossible to realize the wireless communication between the vehicle and the ground, and the mobile authorization calculated by the trackside ATC. It cannot be sent to the on-board ATC, which will result in emergency braking of the train. The power failure of the control center will also cause the ATS application server, ATS database server, etc. to fail to work normally, and the train operation plan cannot be sent to the train. Especially for fully automatic driverless lines, this situation will affect the train's inability to continue to operate and the travel of passengers because there is no driver on the train.
现在越来越多城市在建设城市轨道交通，会进行规划建设备用控制中心，避免主用控制中心在出现灾备情况下，不会影响地铁正常运营。特别是全自动无人驾驶线路，都进行建设了备用控制中心，目前国内建设的全自动无人驾驶线路基本都有建设备用控制中心，比如上海地铁10号线、成都地铁9号线、郑州地铁10号线等。Now more and more cities are building urban rail transit, and planning and building backup control centers will prevent the main control center from affecting the normal operation of the subway in the event of disaster recovery. Especially for fully automatic driverless lines, backup control centers have been built. At present, all fully automatic driverless lines built in China basically have backup control centers, such as Shanghai Metro Line 10, Chengdu Metro Line 9, and Zhengzhou Metro. Line 10, etc.
目前主备控制中心方案存在一定缺陷。1，比如主控中心与备控中心并不能同时在线，需采用切换设备进行切换，也就是主控中心与备控中心采用了相同设备IP，要么主控中心在线工作，断开了备控中心关键设备网络；要么备控中心在线工作，断开了主控中心关键设备网络。比如上海地铁10号线采用的是该方案，需维护人员采用切换开关切换主备控制中心的一边在线工作。该方案也称为冷备方案。2，比如备控中心与主控中心设备完全只是简单的冗余，系统启动时，根据备控中心与主控中心设备根据设备健康状态选择一套设备作为主用，当主用状态的设备故障时，继续根据设备健康状态选择另一套设备作为主用，当前面两套设备都故障时，继续根据设备健康状态选择第三套设备作为主用。北京燕房线的主备控制中心采用的就是该方案。该方案也称为主-备-备方案。该方案并没有做到真正灾备中心，仅仅是设备冗余，不可由工作人员人工选择主控中心、备控中心任一边为主用。不利于维护人员管理设备。比如当前维护人员都在主控中心，希望主控中心设备为主用。The current active-standby control center solution has certain defects. 1. For example, the main control center and the standby control center cannot be online at the same time, and a switching device needs to be used for switching, that is, the main control center and the standby control center use the same device IP, or the main control center works online, and the standby control center is disconnected. The key equipment network; or the standby control center works online, disconnecting the key equipment network of the main control center. For example, Shanghai Metro Line 10 adopts this scheme, and maintenance personnel need to use a switch to switch one side of the main and standby control centers to work online. This scheme is also known as the cold standby scheme. 2. For example, the equipment in the standby control center and the main control center is simply redundant. When the system starts, a set of equipment is selected as the main device according to the health status of the equipment in the standby control center and the main control center. When the equipment in the main state fails , continue to select another set of equipment as the main use according to the health status of the equipment, and continue to select the third set of equipment as the main use according to the health status of the equipment when the previous two sets of equipment are faulty. This scheme is adopted by the main and standby control centers of Beijing Yanfang Line. This scheme is also known as the active-standby-standby scheme. This solution does not have a real disaster recovery center, but only has redundant equipment. The staff cannot manually select either the main control center or the backup control center as the main control center. It is not conducive to maintenance personnel to manage equipment. For example, the current maintenance personnel are all in the main control center, and it is hoped that the main control center equipment is mainly used.

具体实施方式Detailed ways
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
本发明提供的一种城市轨道交通信号系统用的控制中心主备系统。首先做到灾备功能，即主控中心的设备冗余，备控中心与主控中心哪边为主用可由工作人员在界面选择。其次涉及车地无线通信采用基于LTE组网方案，主控中心包含A网、B网不同频率两套DCS关键设备，其中一套A网主用，一套B网备用。备控中心包含B网一套DCS关键设备并为主用，也称为主-备-主方案。The invention provides a main and standby system of a control center for an urban rail traffic signal system. First, the disaster recovery function is achieved, that is, the equipment of the main control center is redundant, and which side of the standby control center and the main control center is the main one can be selected by the staff on the interface. Secondly, the vehicle-ground wireless communication adopts an LTE-based networking solution. The main control center includes two sets of DCS key equipment with different frequencies of A network and B network, one of which is for main use and one for B network. The standby control center includes a set of key DCS devices on the B network and is used as the main device, also known as the active-standby-active solution.
1、本发明主备控制中心网络设备示意图如图1所示。1. A schematic diagram of the network equipment of the active and standby control center of the present invention is shown in FIG. 1 .
1.1主备控制中心网络设备示意图，进行描述网络架构、关键网络设备布置、连接等。处理信号系统车地无线通信的关键设备布置在主控中心、备控中心。信号系统车地无线通信采用两个网段频率，提高系统可靠性，两个网段分别为A网、B网，其中A网、B网采用频道与当地无线通信委员会申请获取。1.1 Schematic diagram of the network equipment of the active and standby control center, to describe the network architecture, key network equipment layout, connection, etc. The key equipment for processing the vehicle-ground wireless communication of the signal system is arranged in the main control center and the backup control center. The vehicle-ground wireless communication of the signal system adopts two network segment frequencies to improve the reliability of the system.
1.2A网采用一个频率，B网采用不同于A网频率，其中A网信息经过红网骨干网交换机，红网主交换机。B网信息经过蓝网骨干网交换机，蓝网主交换机。两个网络相互独立组网，设备相互独立，提高网络冗余性。1.2 The A network adopts a frequency, and the B network adopts a frequency different from that of the A network, in which the information of the A network passes through the red network backbone network switch and the red network main switch. The B network information passes through the blue network backbone network switch and the blue network main switch. The two networks are networked independently of each other, and the devices are independent of each other to improve network redundancy.
1.3信号系统中各子系统的信息传递、车载轨旁的信息传递都需要依靠DCS(网络传输系统)。1.3 The information transmission of each subsystem in the signal system and the information transmission of the vehicle trackside all need to rely on DCS (network transmission system).
主控中心包含关键网络设备：两套网络设备，分别为A网网络设备，B网网络设备，具体为信号路由器A，核心网服务器A，红网主交换机，红网骨干网；信号路由器B，核心网服务器B，蓝网主交换机，蓝网骨干网。其中蓝网主交换机为冷备，因为主交换机只能有一个接入，由于备控中心有一个蓝网交换机，因此主控中心的蓝网主交换机正常工作时不接入。冷备有两种实现方式，一种是设备断电，另一种是设备正常启动，但与外部连接的网线断开。本方案采用第二种方式的冷备方式，主要优点为，当需要采用冷备的蓝网主交换机时，可以快速接入系统，减少切换时间，减少影响运营时间。而采用设备断电的冷备方式，担心现场维护人员误操作，使得主备控制中心交换机均在线。The main control center includes key network equipment: two sets of network equipment, namely A network network equipment, B network network equipment, specifically signal router A, core network server A, red network main switch, red network backbone network; signal router B, Core network server B, blue network main switch, blue network backbone network. Among them, the blue network master switch is a cold backup, because the master switch can only have one access, and because the standby control center has a blue network switch, the blue network master switch in the main control center is not connected when it is working normally. There are two implementations of cold backup, one is that the device is powered off, and the other is that the device is normally started but disconnected from the externally connected network cable. This solution adopts the second method of cold backup. The main advantage is that when the blue network master switch of cold backup is required, it can quickly access the system, reduce the switching time, and reduce the impact on operation time. In contrast, the cold backup method in which the equipment is powered off is worried that the on-site maintenance personnel will make misoperations, so that the switches in the active and standby control centers are all online.
在图中可看到主控中心冷备的蓝网主交换机与蓝网骨干网、核心网B网服务器(EPC-B)进行了虚线连接，代表正常情况是断开。A网网络关键设备仅布署在主控中心，仅有一套，相关设备均为主用。In the figure, it can be seen that the blue network main switch in the cold backup of the main control center is connected with the blue network backbone network and the core network B network server (EPC-B) by a dotted line, which means that the normal situation is disconnected. Network A network key equipment is only deployed in the main control center, there is only one set, and the related equipment is mainly used.
备控中心包含关键网络设备：一套B网网络设备，具体为信号路由器B，核心网服务器B，蓝网主交换机，蓝网骨干网。The standby control center includes key network equipment: a set of B network network equipment, specifically the signal router B, the core network server B, the blue network main switch, and the blue network backbone network.
1.4正常情况，备控中心的EPC-B为主用，备控中心的蓝网交换机主用。蓝网主交换机有且仅有一台接入网络。主控中心的B网信号网路由器与备控中心的B网信号网路由器相连，采用两根网络用于GRE隧道互联。主控中心的B网信号网路由器与备控中心的蓝网主交换机相连，采用一根网络进行互联。1.4 Under normal circumstances, the EPC-B of the standby control center is the main function, and the blue network switch of the standby control center is the main function. The bluenet master switch has one and only one access network.

3、如图3所示，本发明主备控制中心ATS应用服务器判断主备状态流程为：3. As shown in FIG. 3 , the process of judging the active and standby states by the ATS application server of the active and standby control center of the present invention is as follows:
3.1ATS应用服务器应用程序进行启动、或在运行中。3.1 The ATS application server application is started or is running.
3.2ATS应用服务器应用程序通过配置参数或IP地址判断本机所在位置，在主控中心还是备控中心。如果是在主控中心，则进行3.3。如果是在备控中心，则进行3.6。3.2 The ATS application server application program determines the location of the machine through configuration parameters or IP address, whether it is in the main control center or the standby control center. If it is in the main control center, go to 3.3. If it is in the standby control center, go to 3.6.
3.3本机所在位置在主控中心，继续判断主用中心是在主控中心还是备控中心。如果主用中心是在主控中心，则进行3.4。如果是在备控中心，则进行3.5。3.3 The location of the machine is in the main control center, continue to judge whether the main control center is in the main control center or the standby control center. If the main center is the main control center, go to 3.4. If it is in the standby control center, go to 3.5.
3.4本机所在位置在主控中心，主用中心是在主控中心，继续判断主控中心另一台ATS应用服务器是否为主用。如果是主用，那么本机设置为备用状态。如果是备用或者未启动，那么本机设置主用状态。3.4 The location of the machine is in the main control center, and the main use center is in the main control center. Continue to judge whether another ATS application server in the main control center is the main use. If it is the main use, then the machine is set to the standby state. If it is standby or not started, the machine is set to the active state.
3.5本机所在位置在主控中心，主用中心是在备控中心，本机设置为备用状态。3.5 The location of the machine is in the main control center, the main center is in the standby control center, and the machine is set to the standby state.
3.6本机所在位置在备控中心，继续判断主用中心是在主控中心还是备控中心。如果主用中心是在主控中心，本机设置为备用状态。如果主用中心是在备控中心，且备控中心仅一套服务器的话，那么本机设置为主用状态。针对备控中心两套服务器的话，判断方法与主控中心一致，如3.4。3.6 The location of the machine is in the standby control center, continue to judge whether the main center is in the main control center or the standby control center. If the main center is the main control center, the machine is set to the standby state. If the active center is in the standby control center, and the standby control center has only one set of servers, then the local machine is set to the active state. For the two sets of servers in the standby control center, the judgment method is the same as that of the main control center, such as 3.4.
3.7针对主控中心两套ATS应用服务器，通过网络及串口两种方式通信，避免由于单一的通信故障导致无法读取对方状态，可提高系统可靠性。3.7 For the two sets of ATS application servers in the main control center, they communicate through the network and the serial port to avoid the inability to read the status of the other party due to a single communication failure, which can improve the reliability of the system.
当网络及串口通信都故障，此时由于无法获取另一台服务器设备状态，备机升级为主机，当通信恢复后，可能会出现双机现象，此时首先检测到对方是主用服务器，并且本机处于主用状态的服务器会进行自动退出，避免双主机现象。由于通信采用了网络及串口两种通信方式，同时出现故障的概率是很小，因此这种情况较少出现。When both the network and serial communication fail, the standby server is upgraded to the host because the status of the other server cannot be obtained. When the communication is restored, a dual-server phenomenon may occur. At this time, it is first detected that the other party is the active server, and The server in the active state of the machine will automatically exit to avoid the phenomenon of dual hosts. Since the communication adopts two communication methods of network and serial port, the probability of failure at the same time is very small, so this kind of situation rarely occurs.
3.8主用中心在主控中心还是在备控中心，由行调工作人员通过行调ATS工作站选择或设置，未设置缺省情况下主用中心在主控中心。3.8 Whether the main center is in the main control center or the standby control center is selected or set by the dispatching staff through the dispatching ATS workstation. The main control center is the main control center by default if it is not set.

Any person skilled in the art can easily think of various equivalents within the technical scope disclosed by the present invention. Modifications or substitutions should be included within the protection scope of the present invention.
