With the continuous improvement of the technical equipment level and the management level in the rail transit industry, the cloud platform architecture becomes the inevitable development direction of the rail transit construction standard. The existing cloud platform architecture adopts a conventional multi-machine redundancy technology, namely, aiming at a control service, a main central main control server and a plurality of standby central main control servers, and a main central standby control server and a plurality of standby central standby control servers exist; for station service business, there is one main station server and multiple standby station servers.
However, in the prior art, the switching among the normal mode, the backup mode and the degradation mode cannot be realized, because the normal mode requires that the master center main control server playing the master role and the master station server provide the control service and the station service; in the backup mode, a backup central backup control server and a backup station server which play a backup role are required to provide control service business and station service business; in the degraded mode, only the standby station server playing the standby role is required to provide station service business.
When providing control service in the prior art, if the main central main control server playing the main role is intact, the main central main control server playing the main role provides control service, and if the main central main control server playing the main role goes down, because the standby central main control server playing the standby role and the standby central main control server playing the standby role are in equal mutual competition, which server provides control service cannot be determined; when the station service is provided, if the primary station server playing the primary role is intact, it is impossible to determine which server provides the station service because the standby station servers playing the standby role have equal mutual competition relationship. Therefore, in the prior art, due to mutual competition among the servers, the switching of the operation modes cannot be realized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to realize the switching of the operation modes, the application provides a cloud platform architecture system, an operation mode switching method, a device, equipment and a medium.
Example 1:
fig. 1 is a schematic structural diagram of a cloud platform architecture system according to some embodiments of the present disclosure, where the cloud platform architecture system includes a main station server 101 and a standby station server 102 with a first priority, a main station server 103 with a second priority, and a main station server 104 with a third priority;
the server at any priority level is used for broadcasting a first running state of the server and receiving second running states broadcasted by other servers, if other servers with higher priorities than the server are determined to be invalid according to the second running states, whether each server with the same priority level as the server fails is judged, if not, the server is switched to a target operation mode corresponding to the priority level of the server, and notification information for switching to the target operation mode is sent to other servers with the priority levels not higher than the priority level of the server.
In this application, the cloud platform architecture system includes server priority levels including a first priority level, a second priority level and a third priority level, where the first priority level is higher than the second priority level, and the second priority level is higher than the third priority level.
The servers with the first priority include an active central main control server 101, a standby central main control server 101, an active first station server 102 and a standby first station server 102, an active central standby control server 103 and a standby central standby control server 103 with the second priority, and an active third station server 104 and a standby third station server 104 with the third priority.
In order to realize switching of operation modes, the server broadcasts a first operation state of the server, wherein the operation state of the server comprises an effective state and a failure state, and therefore the first operation state may be the effective state or the failure state.
Specifically, the broadcast may be performed in a unicast manner, or may also be performed in a multicast manner, and the method for performing broadcast by the server belongs to the prior art, which is not described in detail in this application. The server may broadcast the first running state of itself in real time, or broadcast the first running state of itself at set time intervals, and preferably, the server broadcasts the first running state of itself in real time.
In order to determine whether to switch the operation mode, the server also receives second operation states broadcasted by other servers, according to the received second operation states, the server can determine target second operation states of other servers with higher priority than the server, and according to the target second operation states of other servers with higher priority than the server, whether all other servers with higher priority than the server fail can be determined.
After determining that all the other servers with higher priority than the server itself are invalid, the server determines that the server itself is the server with the highest priority in the effective state in the cloud platform architecture, so that the server determines that the server itself is authorized to switch the operation modes. The server determines whether each server with the same priority level as the server fails or not in order to determine whether to switch the operation mode, determines to switch the operation mode if it is determined that each server with the same priority level as the server fails, and determines not to switch the operation mode because each server with the same priority level as the server cannot execute service business if it is determined that each server with the same priority level as the server fails.
The server switches the operation mode to a target operation mode corresponding to the self priority after determining to switch the operation mode, and sends notification information for switching to the target operation mode to other servers not higher than the self priority, wherein the notification information for switching to the target operation mode is sent to other servers with the same self priority, and the notification information for switching to the target operation mode is sent to other servers with lower self priority, and after receiving the notification information, other servers with the same self priority do not need to judge whether to switch the operation mode again, but can execute service business in the target operation mode.
For example, when the server is the primary central main control server 101 with the first priority, since the priority of the primary central main control server 101 is the highest priority and there is no other server with a higher priority than the primary central main control server 101, the primary central main control server 101 only needs to judge whether each server with the same level as the primary central main control server 101 fails, that is, the primary central main control server 101 judges whether the primary central main control server 101, the standby central main control server 101, the primary first station server 102, and the standby first station server 102 all fail, if it is determined that the servers are all failed unevenly, the primary central main control server 101 determines that the operation mode is the normal mode corresponding to the first priority, and sends notification information of switching to the normal mode to other servers with the first priority, the second priority, and the third priority.
If the server with the second priority is the primary central standby control server 103, the primary central standby control server 103 determines whether other servers with a first priority higher than the second priority of the primary central standby control server 103 all fail according to the second running states broadcast by the other servers, that is, determines whether the primary central main control server 101, the standby central main control server 101, the primary first station server 102 and the standby first station server 102 all fail, and if the primary central standby control server 103 determines that other servers with a first priority higher than the second priority of the primary central standby control server 103 all fail, the primary central standby control server 103 determines whether each server with the same level as the second priority of the primary central standby control server 103 and the standby central standby control server 103 both fail, and if the primary central standby control server 103 determines that the servers do not all fail, the active central standby control server 103 determines that the operation mode is the standby mode corresponding to the second priority, and sends notification information for switching to the standby mode to other servers of the second priority and the third priority.
If the server is a third-priority active third station server 104, the third-priority active third station server 104 determines whether other servers with a first priority and a second priority higher than the third priority of the third-priority active third station server 104 fail according to the second running state broadcast by the other servers, that is, determines whether the active central main control server 101, the standby central main control server 101, the active first station server 102, the standby first station server 102, the active central standby control server 103 and the standby central standby control server 103 all fail, if it is determined that other servers with the first priority and the second priority higher than the third priority of the third-priority active third station server 104 all fail, the third-station active server 104 determines whether other servers with the same level as the third priority of the third-priority active third station server 104 and the standby third station server 104 both fail, if it is determined that the non-uniformity fails, the main third station server 104 determines that the operation mode is the degradation mode corresponding to the third priority.
The system comprises a main and standby central main control server 101 with a first priority, a main and standby first station server 102, a main and standby central standby control server 103 with a second priority, and a main and standby third station server 104 with a third priority; before determining whether to switch to the target operation mode corresponding to the priority of the server, the server of any priority level needs to determine that other servers with higher priorities than the server of the server are all invalid according to the received second operation state broadcasted by other servers, and when the priority of the server is the current highest priority and each server with the same priority level is determined not to be all invalid, the operation mode switching is carried out, because the system firstly determines any server with the highest current priority in an effective state and the server determines whether to switch to the target operation mode corresponding to the priority of the server, the server with the highest current priority and the server with the lower priority provide service services corresponding to the target operation mode, and the main server with the highest priority in the servers executes the service services aiming at different servers capable of executing the same service, if the main server fails, the standby server executes the operation, so that mutual competition among the servers is avoided, and the switching of the operation modes is realized.
Example 2:
in order to determine whether another server with a higher priority than the server itself fails, in the present application, on the basis of the above embodiment, the server with any priority level is specifically configured to, for each other server with a higher priority than the server itself, determine that the other server fails if the second operation state broadcasted by the other server is a failure state, or if the duration of not receiving the second operation state broadcasted by the other server exceeds a preset duration.
In the application, for determining whether each other server with higher priority than the server with higher priority.
Therefore, in order to determine whether the other server fails, the server receives the second operation status broadcasted by the other server, and if the second operation status is the failure status, the server determines that the other server fails.
The server records the time length of the second running state which is not received by the other servers, if the time length of the second running state which is not received exceeds the preset time length, the other servers are determined to be invalid, and if the time length of the second running state which is not received does not exceed the preset time length, the other servers cannot be determined to be invalid; the preset time is predetermined, and if the second running state of the other server broadcast is broadcast once every set time period, the preset time is longer than the set time period.
Example 3:
in order to more accurately perform the operation mode switching, in the present application, on the basis of each of the above embodiments, the server at any priority level is further configured to output prompt information indicating that the operation mode is switched to the target operation mode corresponding to its own priority before switching to the target operation mode corresponding to its own priority, and if receiving a confirmation operation of the user, perform the step of switching to the target operation mode corresponding to its own priority.
In order to more accurately perform the operation mode switching, in the present application, the server of any priority level needs to be confirmed by the user before performing the operation mode switching.
Specifically, after determining the target operation mode corresponding to the priority of the server, the server outputs a prompt message for switching the operation mode to the target operation mode corresponding to the priority of the server. The prompt message may be a prompt message output in a text form or a prompt message output in a voice form, which is not limited in this application.
And if the server receives the confirmation operation of the user, executing the step of switching to the target operation mode corresponding to the self priority. Specifically, the method may include receiving a trigger operation on a displayed confirmation button or other preset buttons through the display screen, or performing a subsequent step of switching to a target operation mode corresponding to the priority of the user according to the received confirmation operation, such as pressing, sliding, and clicking operations at a preset position on the display screen.
Example 4:
in order to implement service business execution after switching to the target operation mode, on the basis of the foregoing embodiments, in this application, after the server at any priority level is further configured to send notification information for switching to the target operation mode to another server that is not higher than its own priority level, if it is determined that a station server at the same priority level as its own cannot execute the station service business corresponding to the target operation mode, a control request is sent to the station server identified by the identification information according to the identification information of the station server lower than its own priority level, so as to control the station server to execute the corresponding station service business.
In the application, in order to implement the service business executed after switching to the target operation mode, after the server sends the notification information of switching to the target operation mode to other servers with the priority level not higher than the own priority level, the server also determines whether the station server with the same priority level as the own server can execute the station service business.
Specifically, if the server does not include a station server in the server having the same priority level as the server itself, or if the station server having the same priority level as the server fails, it may be determined that the station server having the same priority level as the server itself cannot execute the station service.
When the server determines that the station server with the same priority as the server can not execute the station service business corresponding to the target operation mode, the server determines the identification information of the station server with the lower priority than the server and sends a control request to the station server identified by the identification information, so that the station server is controlled to execute the corresponding station service business according to the information carried in the control request after receiving the control request.

Because the server corresponding to the second priority does not include the station server, the central standby control server 1 determines the identification information of the station 1 main control server 1 and the station 2 main control server 1 of the third priority, sends control requests to the station 1 main control server 1 and the station 2 main control server 1, controls the station 1 main control server 1 and the station 2 main control server 1 to switch to the standby mode corresponding to the second priority, and executes the station service business of the station 1 and the station service business of the station 2.
