Description

[0001] The present application relates to the field of train control technology, in particular to a train master-slave control center switching control method and device and related equipment. BACKGROUND

[0002] At present, most of the automatic train supervision systems (ATS) mainly adopt the redundant deployment strategy of control center double host. The so-called redundant strategy of double host means that each control center has a master-slave application server, a history server and a communication interface server. When the master application server of the master control center fails or is closed, the master application server of the standby control center is automatically upgraded to the master.

[0003] The switching mode of the master-slave control center mainly includes hot standby or cold standby. The cold standby mode of the standby control center is only started when needed. This mode has the problems of long switching time, slow recovery of business functions and inability to realize seamless switching because the system and ATS service of the standby control center need to be started during switching. The hot standby mode of the standby control center starts the signal interface server before switching. This mode has the problems of complex network relationship, doubled network data link, complex network link switching logic and increased network redundancy risk because the system and ATS service of the standby control center need to be started during switching. Therefore, how to better switch the devices in the master-slave control center for controlling trains is very important. SUMMARY

[0030] It should be noted that the equipment shown in the train monitoring system is only part of the equipment, and there are other equipment not shown, such as each service device (server) in the main control center is two, Figure 1 Each service device is shown as one, and the other service device is Figure 1 Each service device shown is identical and is used as a backup service device for each service device. Similarly, each service device in the backup control center is also two, Figure 1 Each service device of the backup control center is shown as one, and the other service device is connected to Figure 1 Each service device shown is identical, Figure 1 Each service device in the backup control center is a backup service device corresponding to each service device in the active control center.

[0031] In the embodiment of the present application, the switching control device obtains data information of each of the plurality of primary service devices in the control center. In the case where a target primary service device among the plurality of primary service devices is determined to be faulty, the switching control device controls to obtain corresponding data information from a standby service device corresponding to the target primary service device. Before being used, each standby service device in the control center is in a state of device running and network disconnection. The service devices in the control center are arranged in a manner of conventional cold standby, and the network addresses IP specified in the primary control center and the standby control center are consistent, the network relationship is simpler, and the problems of network data link multiplication, network link switching logic implementation complexity, and network redundancy risk increase are reduced. Unlike the conventional cold standby, each service device in the standby control center is always in a state of being powered on (i.e., device running) and network connection disconnection. When the service devices in the control center are switched by the hot standby and cold switching manner, the switching time of the devices is short, the business function is recovered quickly, and the switching is easy and imperceptible. The service devices in the control center can be switched more quickly, flexibly and effectively, so as to improve the efficiency of obtaining data information of the train.

[0032] Please refer to Figure 2 , Figure 2 is a flowchart of a train primary and standby control center switching control method provided by the embodiment of the present application, as Figure 2 shown in the embodiment of the present application, the train primary and standby control center switching control method can be applied to a switching control device, which is arranged in a switching control device. The method can at least include the following steps.

[0033] S201: Obtain data information of each of the plurality of primary service devices in the control center.

[0034] In the embodiment of the present application, the switching control device can obtain data information of each of the plurality of primary service devices in the control center. In some embodiments, the control center can include, but is not limited to, ATS application servers, communication interface servers, communication servers, vehicle dispatching servers, database servers, dispatching workstations and other service devices.

[0035] In one embodiment, the control center includes a primary control center, and the plurality of primary service devices are in the primary control center. In addition to the plurality of primary service devices, the primary control center also includes a standby service device corresponding to each primary service device, so that when a primary service device fails, the switching control device can control to obtain corresponding data information by switching to the standby service device corresponding to the primary service device.

[0036] In one embodiment, the control center further comprises a backup control center, the backup control center comprises a plurality of backup service devices, each service device of the backup control center is configured to obtain data information from each service device of the backup control center when the primary control center fails and the data information cannot be obtained from each service device of the primary control center. In some embodiments, the network address of each backup service device is the same as the network address of the corresponding primary service device, so that the network relationship is simpler, the network data link is not doubled, and the complexity of the network link switching logic is reduced.

[0037] In one embodiment, when the primary service device fails, a corresponding backup service device can be selected from each backup service device to obtain corresponding data information. In one example, when the primary service device fails, a corresponding backup service device can be selected from each backup service device in the primary control center to obtain corresponding data information, or a corresponding backup service device can be selected from each backup service device in the backup control center to obtain corresponding data information.

[0038] In one embodiment, the plurality of backup service devices comprises a plurality of master backup service devices and a slave backup service device corresponding to each master backup service device, wherein the priority of the master backup service device is higher than that of the slave backup service device. Specifically, when the switching control device detects that the primary control center fails and the data information cannot be obtained from each service device of the primary control center, the switching control device can be controlled to obtain corresponding data information from each master backup service device of the backup control center first, and if the corresponding data information cannot be obtained from each master backup service device, the switching control device is further controlled to switch to each slave backup service device of the backup control center to obtain corresponding data information.

[0039] In one embodiment, each service device in the primary control center can determine whether the service device in the primary control center is a primary service device or a backup service device by marking the device status, and the marking method of the device status can be identified by numbers, words, letters, etc. For example, the primary service device in the primary control center is marked with the number 1, and the backup service device in the primary control center is marked with the number 2.

[0040] The service devices in the backup control center can also determine whether the backup service devices in the backup control center are master backup service devices or slave backup service devices by marking the device states. The state marks of the service devices in the backup control center can be different from those of the service devices in the master control center, so as to distinguish the service devices in different states in each control center. For example, the master backup service device in the backup control center is marked with the number 3, and the slave backup service device in the backup control center is marked with the number 4.

[0041] Marking the device states helps to quickly and effectively select the corresponding service device for switching when the service device is switched, so as to improve the efficiency of device switching.

[0042] S202: In a case where it is determined that a target master service device in each master service device fails, the switching control apparatus controls to acquire corresponding data information from a backup service device corresponding to the target master service device, wherein each backup service device in the control center is in a device running and network disconnected state before being used.

[0043] In the embodiments of the present application, the switching control apparatus can control to acquire corresponding data information from a backup service device corresponding to a target master service device in each master service device in a case where it is determined that the target master service device fails, wherein each backup service device in the control center is in a device running and network disconnected state before being used.

[0044] By controlling each backup service device to be in a device running and network disconnected state before being used, it is helpful to quickly use the backup service device by establishing a network connection when the backup service device is used, reduce the device startup time caused by starting the device in the prior art, and improve the efficiency of device switching.

[0045] In one embodiment, the control center includes a master control center, the master control center includes a plurality of master service devices and a backup service device corresponding to each master service device; when the switching control apparatus controls to acquire corresponding data information from a backup service device corresponding to a target master service device in each master service device in a case where it is determined that the target master service device fails, it can select a first backup service device corresponding to the target master service device from the master control center in a case where it is determined that the target master service device in the master control center fails; establish a network connection of the first backup service device, and control to acquire corresponding data information from the first backup service device.

[0046] In one embodiment, when the switching control device determines that the target primary service device in the primary control center fails, and selects the first backup service device corresponding to the target primary service device from the primary control center, the switching control device can directly select the target backup service device corresponding to the target primary service device from the backup service devices in the primary control center, and determine the target backup service device as the first backup service device.

[0047] Specifically, the embodiments of the present application can be illustratively described in combination with Figure 3 and Figure 4 , and Figure 3 is a schematic diagram of service device switching in a primary control center provided by an embodiment of the present application, Figure 4 is a schematic diagram of service device switching in a primary control center provided by an embodiment of the present application. As Figure 3 indicated, the primary control center includes a primary service device and a backup service device, wherein the primary service device includes an ATS application server (primary) 31 and a communication server (primary) 32, and the backup service device includes an ATS application server (backup) 33 and a communication server (backup) 34 corresponding to the primary service device. The ATS application server (primary) 31 can obtain data information of a train through the communication server (primary) 32, and the communication server (primary) 32 can obtain data information of the train from an automatic train protection subsystem (ATP) and / or an automatic train operation system (ATO) 35. At this time, the ATS application server (backup) 33 and the communication server (backup) 34 as backup service devices are in a state of device running and network disconnection. When the communication server (primary) 32 as the primary service device in the primary control center fails, the switching control device can establish network connection of the communication server (backup) 34 as the backup service device in the primary control center, so as to control switching from the communication server (primary) 32 as the primary service device to the communication server (backup) 34 as the backup service device in the primary control center to obtain corresponding data information, as Figure 4 indicated.

[0048] In some embodiments, the switching control device can disconnect the network connection of the failed target primary service device, and in other embodiments, the switching control device can keep the network connection of the failed target primary service device, so that the switching control device can timely obtain the signal of the target primary service device failure recovery after the target primary service device failure recovery, so as to flexibly switch back to the target primary service device from the first standby service device, obtain data information from the target primary service device, the network link is simpler and more direct, and the corresponding data information can be more efficiently and quickly obtained.

[0049] In one embodiment, when the switching control device determines that the target primary service device in each primary service device fails, and controls to obtain the corresponding data information from the standby service device corresponding to the target primary service device, the switching control device can determine that the target primary service device in the primary control center fails, obtain the first used amount of the service device in the primary control center and the second used amount of the service device in the standby control center, and if it is detected that the difference between the first used amount and the second used amount is greater than a first preset threshold, determine to select a third standby service device corresponding to the target primary service device from the standby control center; establish a network connection of the third standby service device, and control to obtain the corresponding data information from the third standby service device. If it is detected that the difference between the first used amount and the second used amount is less than or equal to the first preset threshold, it is determined to select a fourth standby service device corresponding to the target primary service device from each standby service device in the primary control center; establish a network connection of the fourth standby service device, and control to obtain the corresponding data information from the fourth standby service device.

[0050] When the switching control device determines that the ratio of the number of used service devices in the primary control center to the number of all service devices in the primary control center and the standby control center is the first used amount, the switching control device can obtain the number of used service devices in the primary control center and the number of used service devices in the standby control center; determine that the ratio of the number of used service devices in the primary control center to the number of all service devices in the primary control center and the standby control center is the first used amount; determine that the ratio of the number of used service devices in the standby control center to the number of all service devices in the primary control center and the standby control center is the second used amount.

[0051] Further, the switching control device can further acquire a third usage amount of each standby service device in the primary control center (i.e., a ratio of the number of used standby service devices in the primary control center to the number of all service devices in the control center) and a second usage amount of each service device in the standby control center (i.e., a ratio of the number of used service devices in the standby control center to the number of all service devices in the control center), and if a difference between the third usage amount and the second usage amount is greater than a second preset threshold, determine to select a third standby service device corresponding to the target primary service device from the standby control center; establish a network connection of the third standby service device, and control to acquire corresponding data information from the third standby service device. If the difference between the third usage amount and the second usage amount is less than or equal to the second preset threshold, determine to select a fourth standby service device corresponding to the target primary service device from each standby service device in the primary control center; establish a network connection of the fourth standby service device, and control to acquire corresponding data information from the fourth standby service device.

[0052] By comparing the third usage amount of each standby service device in the primary control center with the second usage amount of each service device in the standby control center, when the difference between the third usage amount and the second usage amount is greater than the second preset threshold, it is determined that the usage rate of each standby service device in the primary control center is greater than the usage rate of each service device in the standby control center, and therefore the second standby service device corresponding to the target primary service device can be selected from each service device in the standby control center. Similarly, when the difference between the third usage amount and the second usage amount is less than or equal to the second preset threshold, it is determined that the usage rate of each standby service device in the primary control center is less than the usage rate of each service device in the standby control center, and therefore the second standby service device corresponding to the target primary service device can be selected from each standby service device in the primary control center. In this way, the second standby service device corresponding to the target primary service device can be more flexibly selected between the primary control center and the standby control center, to improve the device switching efficiency and the data acquisition efficiency.

[0053] In an embodiment, the switching control device, when selecting the third backup service device corresponding to the target primary service device from the backup control center, can control to select the third backup service device corresponding to the target primary service device from the primary backup service device of the backup control center first, and if the corresponding data information cannot be obtained from the third backup service device corresponding to the target primary service device selected from the primary backup service device of the backup control center, control to select the third backup service device corresponding to the target primary service device from the secondary backup service device of the backup control center, and control to obtain the corresponding data information from the third backup service device corresponding to the target primary service device selected from the secondary backup service device.

[0054] In an embodiment, the control center further comprises a backup control center comprising a plurality of backup service devices; when the switching control device determines that the target primary service device among the primary service devices fails, and controls to obtain the corresponding data information from the backup service device corresponding to the target primary service device, if the corresponding data information cannot be obtained from the first backup service device, the switching control device determines that the first backup service device fails, and selects a second backup service device corresponding to the target primary service device from the backup control center; establishes a network connection of the second backup service device, and controls to obtain the corresponding data information from the second backup service device.

[0055] In an embodiment, the backup control center comprises a plurality of primary backup service devices and secondary backup service devices; when the switching control device selects the second backup service device corresponding to the target primary service device from the backup control center, the switching control device can select a target primary backup service device corresponding to the target primary service device from each primary backup service device of the backup control center, and determine that the target primary backup service device is the second backup service device, if the corresponding data information cannot be obtained from the target primary backup service device, control to select a target secondary backup service device corresponding to the target primary service device from each secondary backup service device of the backup control center, and determine that the target secondary backup service device is the second backup service device, and obtain the corresponding data information from the target secondary backup service device.

[0056] Further, the switching control device can acquire a fourth usage amount of each master-slave service device in the backup control center (i.e., a ratio of the number of the used master-slave service devices in the backup control center to the number of all the backup service devices in the backup control center) and a fifth usage amount of each slave backup service device in the backup control center (i.e., a ratio of the number of the used slave backup service device in the backup control center to the number of all the backup service devices in the backup control center), and determine to select the second backup service device corresponding to the target master service device from each slave backup service device in the backup control center if a difference between the fourth usage amount and the fifth usage amount is greater than a third preset threshold, or determine to select the second backup service device corresponding to the target master service device from each master-slave service device in the backup control center if the difference between the fourth usage amount and the fifth usage amount is less than or equal to the third preset threshold.

[0057] By comparing the fourth usage amount of each master-slave service device in the backup control center with the fifth usage amount of each slave backup service device, it can be determined that the usage rate of each master-slave service device in the backup control center is greater than that of each slave backup service device if the difference between the fourth usage amount and the fifth usage amount is greater than the third preset threshold, and thus the second backup service device corresponding to the target master service device can be selected from each slave backup service device. Similarly, it can be determined that the usage rate of each master-slave service device in the backup control center is less than that of each slave backup service device if the difference between the fourth usage amount and the fifth usage amount is less than or equal to the third preset threshold, and thus the second backup service device corresponding to the target master service device can be selected from each master-slave service device. In this way, the second backup service device corresponding to the target master service device can be more flexibly selected from each master-slave service device and each slave backup service device in the backup control center, so as to improve the device switching efficiency and the data acquisition efficiency.

[0058] In an embodiment, the control center includes a master control center and a backup control center, the master control center includes a plurality of master service devices and a backup service device corresponding to each master service device, and the backup control center includes a plurality of backup service devices; and the switching control device establishes a network connection of each backup service device in the backup control center and controls to acquire corresponding data information from each backup service device in each control center if no corresponding data information is acquired from any service device in the master control center within a preset time range.

[0059] In the case that the data information cannot be obtained from the main control center, the network connection of each service device in the backup control center is established, so that the data information of the train is obtained from the backup control center, thereby reducing the possibility that the data information of the train cannot be obtained in the case that the main control center fails, and improving the reliability and efficiency of obtaining the data information of the train.

[0060] In one embodiment, the switching control device detects whether the failure of the main service device corresponding to any backup service device is recovered in the process of obtaining the corresponding data information from any backup service device; if it is detected that the failure of the main service device corresponding to any backup service device is recovered, the network connection of the any backup service device is disconnected, and the corresponding data information is obtained from the main service device corresponding to the any backup service device. In some embodiments, the switching control device can determine that the failure of the main service device corresponding to any backup service device is recovered when the communication signal of the main service device corresponding to the any backup service device is obtained.

[0061] The embodiments of the present application can obtain the data information of each main service device in the plurality of main service devices in the control center, and in the case that the target main service device in the plurality of main service devices fails, the corresponding data information is obtained from the backup service device corresponding to the target main service device, wherein each backup service device in the control center is in a device running and network disconnection state before being used. In this way, the service devices in the control center can be switched more quickly, flexibly and effectively, so as to improve the efficiency of obtaining the data information of the train.

[0062] Referring to Figure 5 , Figure 5 is a structural schematic diagram of a switching control device provided by the embodiments of the present application, as Figure 5 shown, the switching control device is applied to a switching control device in a train monitoring system, the train monitoring system further includes a control center, the switching control device is in communication connection with the control center, the control center includes a plurality of main service devices and a plurality of backup service devices corresponding to each main service device, and the switching control device includes an obtaining unit 501 and a control unit 502, wherein,
