本发明涉及列车设备信号控制系统，尤其涉及一种支持虚拟连挂作业的列控系统及运行方法。The invention relates to a train equipment signal control system, and in particular to a train control system and an operating method that support virtual coupling operations.
背景技术Background technique
列控技术经历了固定闭塞，移动闭塞的转变，不断的在追求着列车设备前后追踪间隔的更小化，更小的追踪间隔，意味着同样的线路，可以同时运行更多的车，更高的运输能力，可有效降低改扩建线路的成本，更高的运输效率。随着计算机技术、通信技术、控制技术等的发展，基于相对距离的控制技术逐渐变为可能。目前，基于目标-距离的追踪模式，后车的授权最远只能到达前车的车尾。而虚拟连挂技术基于前车的速度、加速度信息，后车的授权可以适当前提，突破前车车尾的限制，可有效缩短前后车间隔，达到提升效率的目的。虚拟连挂旨在通过车车通信，用软连接，代表传统的硬钩技术，将若干辆列车设备通过“软”钩连接，以列车设备群的整体形式运行，逐渐成为列车设备技术研究热点。Train control technology has gone through a transformation from fixed blocking to moving blocking, and is constantly pursuing a smaller tracking interval before and after train equipment. Smaller tracking intervals mean that the same line can run more trains at the same time, with higher The transportation capacity can effectively reduce the cost of rebuilding and expanding lines and achieve higher transportation efficiency. With the development of computer technology, communication technology, control technology, etc., control technology based on relative distance gradually becomes possible. Currently, in the target-distance based tracking mode, the authorization of the following vehicle can only reach the rear of the leading vehicle. The virtual hitch technology is based on the speed and acceleration information of the vehicle in front. The authorization of the vehicle behind can be appropriately predicated, breaking through the restrictions of the rear of the vehicle in front, effectively shortening the distance between the front and rear vehicles, and achieving the purpose of improving efficiency. Virtual coupling aims to use soft connections through vehicle-to-vehicle communication, representing traditional hard hook technology. Several train equipment are connected through "soft" hooks and run as an integral train equipment group. It has gradually become a hot spot in train equipment technology research.

S2、临时限速服务器保存并转发该虚拟连挂命令至对应的列车设备。S2. The temporary speed limit server saves and forwards the virtual connection command to the corresponding train equipment.
具体地，虚拟连挂命令中包含有执行相应作业的列车设备的ID信息，所述步骤S2中，若临时限速服务器检测到存在尚未在其内注册的列车设备时，临时限速服务器向调度中心设备反馈错误回执，并停止下发虚拟连挂命令。调度中心设备以一定时间间隔重新向所述临时限速服务器下发该虚拟连挂命令，所述临时限速服务器在该时间间隔内注册列车设备。当全部列车设备均注册后，临时限速服务器再将虚拟连挂命令转发至对应的列车设备。Specifically, the virtual connection command contains the ID information of the train equipment that performs the corresponding operation. In step S2, if the temporary speed limit server detects that there is a train equipment that has not been registered in it, the temporary speed limit server reports to the dispatcher The central device returns an error receipt and stops issuing virtual connection commands. The dispatch center device re-issues the virtual connection command to the temporary speed limit server at a certain time interval, and the temporary speed limit server registers the train equipment within the time interval. When all train equipment is registered, the temporary speed limit server forwards the virtual connection command to the corresponding train equipment.
列车设备接收到虚拟连挂命令后执行相应的作业，即虚拟连挂作业或解除虚拟连挂连接作业，并在执行完成后向临时限速服务器反馈报告信息。同时，所述列车设备还以一定时间周期向临时限速服务器发送车载报告，本实施例中，该时间周期配置为6秒。当列车设备发生故障时，临时限速服务器可根据该车载报告获知列车设备是否丢失相应的虚拟连挂命令。After receiving the virtual coupling command, the train equipment executes the corresponding operation, that is, the virtual coupling operation or the virtual coupling connection operation, and after the execution is completed, the report information is fed back to the temporary speed limit server. At the same time, the train equipment also sends an on-board report to the temporary speed limit server in a certain time period. In this embodiment, the time period is configured as 6 seconds. When the train equipment fails, the temporary speed limit server can learn whether the train equipment has lost the corresponding virtual connection command based on the on-board report.
所述临时限速服务器将所接收的虚拟连挂命令存储到本地磁盘中，当列车设备丢失虚拟连挂命令时，临时限速服务器可自动补发相应的虚拟连挂命令。或者，当临时限度服务器断电重启后，临时限速服务器可自动向未反馈报告信息的列车设备补发虚拟连挂命令，以防止人工遗漏。The temporary speed limit server stores the received virtual connection command in the local disk. When the train equipment loses the virtual connection command, the temporary speed limit server can automatically reissue the corresponding virtual connection command. Or, when the temporary speed limit server is powered off and restarted, the temporary speed limit server can automatically reissue the virtual connection command to the train equipment that has not fed back the report information to prevent manual omissions.

After receiving the receipt, the configuration is to directly clear the virtual connection command and wait for the dispatch center device to issue the virtual connection command again. Or it can be configured to continue to issue virtual connection commands to some train equipment that has not fed back reporting information until all train equipment feedbacks reporting information, or until it receives virtual connection release information from the dispatch center equipment.

步骤8、虚拟连挂列车设备抵达终点，调度中心设备制定解除虚拟连挂作业信息，并经临时限速服务器转发至列车设备A、B、C，列车设备A、B、C接收并执行该解除虚拟连挂作业信息，并向临时限速服务器反馈报告信息。Step 8. The virtual coupled train equipment arrives at the end point. The dispatch center equipment formulates the cancellation operation information of the virtual coupled train and forwards it to train equipment A, B, and C through the temporary speed limit server. Train equipment A, B, and C receive and execute the cancellation. Virtual connection job information and feedback report information to the temporary speed limit server.
步骤9、临时限速服务器向调度中心设备发送解除虚拟连挂作业信息执行成功回执，并配置为从本地清除该解除虚拟连挂作业信息。Step 9: The temporary speed limit server sends a successful execution receipt of the virtual connection release job information to the dispatch center device, and is configured to locally clear the virtual connection release job information.
本发明提出的列控系统支持虚拟连挂技术，可以有效缩短前后车间隔，达到提升效率的目的。而且，临时限速服务器为列控系统的既有设备，无需新增设备类型，极大降低了成本。The train control system proposed by the present invention supports virtual coupling technology, which can effectively shorten the distance between the front and rear trains and achieve the purpose of improving efficiency. Moreover, the temporary speed limit server is an existing device of the train control system, so there is no need to add new device types, which greatly reduces costs.
