Background
The control card is used as a core component of the control equipment and is in service communication with each service module so as to complete the normal functions of each service module in the system. And when the control card receives the configuration information, storing the configuration information in a local storage space of the control card, so that when the control card is started, the configuration information is loaded and the control equipment is set according to the configuration information. In a communication system, since the network location where the control device is located is very important, the requirement for stability of the control device is very high. In order to ensure normal operation, a standby control card is usually added to switch the control card when the control card fails.
At present, one of the existing control card switching techniques is to power off the system first when the main control card fails, and then replace the failed main control card with the standby control card, so that the device cannot work during card replacement, which affects the working efficiency. In order to improve the method that the on-line switching cannot be carried out, two control cards are generally configured in the control equipment at the same time, when the main control card works, the standby control card needs to acquire all the running data of the main control card in real time and store the running data in the local storage space of the standby control card, so that the standby control card and the main control card are completely consistent in control logic and memory information, and the standby control card can replace the main control card to work when the main control card fails.
However, because the frame architecture basically adopts the ATCA platform, the control card cannot be expanded due to the limitation of the frame architecture, hardware resources and performance are relatively low, configuration information of the system can only be stored in a file mode, synchronization between the main control card and the standby control card can only adopt network data exchange, the coupling and complexity of the whole system are high, and the operation and maintenance data volume of the system is relatively large, so that synchronization cannot be realized.

In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a control card switching method according to an embodiment of the present invention, which is applicable to a situation where a standby control card is started when a master control card fails or is removed from a master card slot. The method may be performed by a control card switching device, which may be implemented in software and/or hardware, typically integrated in an electronic device.
As shown in fig. 1, the method specifically includes the following steps:
and S110, when the main control card is detected to be in a fault state, switching the standby control card from a standby state to a working state.
The master control card may be a control core of the device or the system, and is configured to implement communication with an external device and control the device or the system to complete functions of each module. The standby control card may be a control card for ensuring that the standby control card operates in place of the master control card when the master control card fails, so that the device or system can operate normally. The fault state may include a fault of the master control card, and may also include a non-operating state of the master control card caused by the master control card being moved out of the master slot position. The standby state may be a standby state in which the standby control card is not started and the standby control card is disconnected from both the external communication interface and the communication interface of the internal underlying service card. The operating state may be a state in which the standby control card is used to control the operation of the device or system.
Optionally, at least two card slots may be provided in the device or system. The card slot-based use logic may be divided into a master card slot position and a spare card slot position. It is to be understood that the number of the primary and spare slots may be one, two or more, and is not particularly limited thereto. The control card in the master card slot is often enabled preferentially as a main control card. In other words, the master control card is typically located in the master slot position and the standby control card is typically located in the standby slot position.
Specifically, the standby control card can detect the state of the master control card, so that when the master control card fails or is moved out of the master card slot, the standby control card can be started to ensure the normal operation of the equipment or the system. If the standby control card detects that the main control card is in a normal working state, the standby control card keeps a standby state at the moment; if the standby control card detects that the main control card is in a fault state, the standby control card is started, and the standby control card is switched to a working state.
The detection of the state of the master control card by the standby control card can be that the standby control card is in communication connection with the master control card, and if the communication connection is disconnected and the communication connection is not reestablished within a certain time, for example, if the communication connection between the master control card and the standby control card within 30s is disconnected, the master control card is judged to be in a fault state. Or the master control card sends a signal to the standby control card at intervals so that the standby control card determines that the master control card is in a working state, and if the standby control card does not receive the signal sent by the master control card within a preset number of time intervals, the master control card is judged to be in a failure state.
It should be noted that the method for detecting the state of the primary control card by the standby control card may be selected according to actual requirements, and is not specifically limited in this embodiment.
In order to clearly introduce a method for detecting the state of the master control card by the standby control card, taking the example that the master control card sends a heartbeat message to the standby control card, a specific method is as follows:
and if the heartbeat message sent by the heartbeat state sending thread of the main control card is not received within the preset time length range, determining that the main control card is detected to be in a fault state.
The heartbeat state sending thread is a thread used for sending heartbeat messages. The heartbeat message may be a message that the master control card sends a heartbeat signal to the standby control card at a certain time interval. The heartbeat signal may be a pulse signal used to determine whether the master control card is operating properly. The preset time length range is used for measuring the time length range of whether the master control card works normally, and can be 30s and the like.
Specifically, the standby control card can receive a heartbeat message sent by the main control card in real time or at regular time, and when the heartbeat message is received, the main control card can be determined to work normally; if the heartbeat message is not received within the preset time range, the main control card can be determined to be in a fault state.
Illustratively, the standby control card detects the heartbeat packet sent by the main card at regular time based on the heartbeat state sending thread, for example: every ten seconds. If 3 continuous times of not receiving the heartbeat message of the main control card exist, determining that the main control card is in a failure state, and switching the standby control card to a working state, otherwise, keeping the current standby state of the standby control card unchanged.
And S120, reading system configuration data and system operation and maintenance data in the slave database corresponding to the standby control card so that the standby control card enters a working state based on the system configuration data and the system operation and maintenance data.
Wherein the slave database is a database corresponding to the standby control card, the master database is a database corresponding to the master control card, and the master database and the slave database may be configured in the server. The master database and the slave database store system configuration data and system operation and maintenance data. The system configuration data and the system operation and maintenance data of the master database are obtained according to data generated by interaction between the master control card and external equipment and the like. Optionally, the system configuration data and the system operation and maintenance data of the slave database are synchronized with the system configuration data and the system operation and maintenance data of the master database corresponding to the master control card. The system configuration data may be data for configuring the control card so that the control card can control the device or the system, and the system operation and maintenance data may include interaction data generated by the master control card interacting with the device or the system, and may also include data generated by the master control card running.
Illustratively, the master database and the slave database may be Mysql databases. The Mysql database supports master-slave synchronization, and master-slave synchronization of system configuration data and system operation and maintenance data can be realized through real-time synchronization between the master database and the slave database.
It should be noted that, when the master control card normally works, the system configuration data required by the control card configuration and the interactive data generated in the working process of the master control card are stored in the master database. The slave database can be updated according to the data change in the master database, so that the slave database and the master database are in a data master-slave synchronization state. The data synchronization mode of the slave database and the master database may be that when the slave database detects the data change of the master database, the data in the slave database is updated according to the data in the master database, or the data in the master database is acquired from the slave database in real time and the data in the slave database is updated. The advantages of real-time synchronization of the master database and the slave database are that: the method can reduce data synchronization when the master control card and the standby control card are switched, further reduce the system recovery time, and effectively avoid the problems of data loss and low switching efficiency caused by control card switching.
Specifically, if the standby control card is switched to the working state, the standby control card needs to be configured, and the standby control card can acquire the system operation and maintenance data in the slave database to ensure that the system or the device can continuously work without being affected by the failure of the master control card. The standby control card can read the system configuration data in the slave database to configure the standby control card, so that the configured standby control card is the same as the original main control card in configuration. And when the standby control card works, the standby control card can complete the work based on the system operation and maintenance data in the slave database. When the standby control card is switched to a working state, the external communication interface and the communication interface of the internal bottom layer service card can be opened to take over all management tasks.
On the basis of the above embodiment, in order to make the standby control card distinguishable from the master control card and avoid the problem of work confusion between the standby control card and the master control card, the standby control card may be started later than the master control card for a period of time.
Optionally, the start script is called to start the control card management program.
The start script may be a script code for starting a hypervisor of the primary control card and the standby control card. The control card management program may include a control card management program of the master control card and a control card management program of the standby control card for managing start and operation of the control cards. When the system is simultaneously provided with the main control card and the standby control card, the starting time of the control card management program in the starting script of the standby control card is later than the starting time of the control card management program in the starting script of the main control card.
Specifically, when the master control card and the standby control card are installed in the system at the same time, the control card may be started by calling a start script. The starting script of the master control card can be immediately executed to start the corresponding control card management program; the start script of the standby control card can be provided with a time delay program to delay a certain time and then start the corresponding control card management program.
It should be noted that, the system configuration data and the system operation and maintenance data of the master control card and the standby control card are stored in the master database and the slave database, and the synchronization problem of the databases does not need to be concerned in the process of switching the master control card to the standby control card. The reason is that: the services of the master database and the slave database are started following the start of the system, usually prior to the start of the business system. When the service system needs to switch the master control card to the standby control card, master-slave synchronization of the master database and the slave database is completed, and the standby control card can be directly converted into a working state.
Compared with the technical scheme that the configuration data and all the operation data of the main control card need to be stored locally on the standby control card in the prior art, the data synchronization efficiency is low during switching of the control cards, the problem of influencing the system operation efficiency is solved, the convenience of data synchronization between the main control card and the standby control card is improved, the switching efficiency of the main control card and the standby control card is improved, and the system operation efficiency is improved, the standby control card is configured in a mode of reading system configuration data from the database, so that the selectivity of the standby control card is more flexible, the memory space of the main control card and the standby control card is released, the space limitation of the control card is greatly solved, the processing performance and the storage capacity are greatly improved, and the technical effect of improving the reliability of the system is further achieved.
Example two
Fig. 2 is a flowchart of a control card switching method according to a second embodiment of the present invention, and in this embodiment, on the basis of the foregoing embodiments, reference may be made to the technical solution of this embodiment for specific conditions for whether to switch a standby control card to a standby state. Optionally, if the control card switch-back mode preconfigured in the system is in the on state, the operation of switching the master control card to the working state is executed. The same or corresponding terms as those in the above embodiments are not explained in detail herein.
As shown in fig. 2, the method specifically includes the following steps:
s210, when the main control card is detected to be in the fault state, the standby control card is switched to the working state from the standby state.
S220, reading system configuration data and system operation and maintenance data in a slave database corresponding to the standby control card so that the standby control card enters a working state based on the system configuration data and the system operation and maintenance data.
And S230, if the control card switch-back mode pre-configured by the system is in the open state, executing the operation of switching the master control card to the working state.
The control card switch back mode may be a mode in which, when it is detected that the failure state of the master control card is released, the master control card is started to be in an operating state, and the standby control card is switched back to a standby state.
Specifically, if the control card switch-back mode pre-configured in the system is in the on state, when the failure state of the master control card is detected to be released, the master control card can be restarted to manage and control the system or the device, and the standby control card is switched back from the working state to the standby state. When the master control card is started, the master database can synchronize system operation and maintenance data during the fault period of the master control card from the slave database so that the master control card can work normally.
Optionally, before the master control card is switched to the working state, it may be further determined whether the master control card is placed in the master slot position, and if so, an operation of switching the master control card to the working state is performed.
Specifically, if the master control card is located in the master card slot, the master control card can be switched to a working state, and the standby control card can be switched to a standby state; if the master control card is located in the standby card slot position outside the master card slot position, the original master control card can be used as the standby control card and set to be in a standby state, and the working state of the original standby control card is kept unchanged.
Optionally, before the master control card is switched to the working state, whether the failure of the master control card is eliminated may be determined according to whether the standby control card receives the heartbeat message sent by the master control card. The specific mode can be as follows: and if receiving the heartbeat message sent by the heartbeat state sending thread of the main control card, switching the main control card to a working state and switching the standby control card from the working state to a standby state.
Specifically, the standby control card may detect the state of the main control card when in a working state, and if a heartbeat message sent by a heartbeat state sending thread of the main control card is received, it indicates that the failure state of the main control card is released, and the standby control card may be reused. At this time, the master control card may be switched to the working state and the standby control card may be switched from the working state to the standby state according to the switching mode.
On the basis of the above embodiments, three cases are described without switching the master control card to the working state and the standby control card to the standby state.
First, if the control card switch-back mode is not in the on state, the master control card is switched to the standby state.
Specifically, if the control card switch-back mode is not started, the working state of the standby control card is kept unchanged, and if the fault state of the main control card is relieved, the main control card is switched to the standby state to be used when the standby control card fails. In this case, the master database will synchronize the data according to the data in the slave database.
And secondly, if the standby control card is arranged in the main card slot position, the main control card is switched to a standby state.
Specifically, if the standby control card is placed in the master card slot, it is indicated that the original standby control card is used as a new master control card and is put into use. Even if the fault of the original master control card is removed, the back switch is not needed, the control cards in the master card slot position are kept in the working state, and the rest control cards are switched to the standby state.
And thirdly, if the master control card is not arranged in the master card slot position, switching the master control card to a standby state.
Specifically, if no control card exists in the master card slot, that is, the master control card and the standby control card are both placed in different standby card slots, the working state of the standby control card can be kept unchanged, and the master control card is switched to the standby state.
In the technical scheme of the embodiment, when the master control card is detected to be in a fault state, the standby control card is switched from the standby state to the working state, and the system configuration data and the system operation and maintenance data in the slave database corresponding to the standby control card are read, so that the standby control card enters the working state based on the system configuration data and the system operation and maintenance data, compared with the technical scheme that the configuration data and all the operation data of the master control card need to be stored locally on the standby control card in the prior art, when the fault of the master control card is relieved, if a switch-back mode of the control card configured in advance by the system is in an open state, the operation of switching the master control card to the working state is executed, the problems of low data synchronization efficiency and system working efficiency are solved, the convenience of data synchronization between the master control card and the standby control card and the switching efficiency of the master control card and the standby control card, and the standby control card is configured in a mode of reading system configuration data from the database, so that the selectivity of the standby control card is more flexible, the memory space of the main control card and the standby control card is released, the space limitation of the control card is greatly solved, the processing performance and the storage capacity are greatly improved, and the technical effect of improving the reliability of the system is further improved.

In order to enable the standby control card to detect the state of the master control card, the communication IP between the master control card and the standby control card may be configured in advance, so that the master control card may send a heartbeat message to the standby control card. Meanwhile, a cut-back mode can be set to be in an opening or closing state so as to determine the starting logics of the main control card and the standby control card.
S330, calling the starting script to start the management program.
Specifically, the start script may be called to control the start of the hypervisor of the standby control card later than the start of the hypervisor of the master control card, for example: the hypervisor controlling the standby control card is started 30 seconds after the hypervisor controlling the primary control card is started. By the method, the problem of master robbing abnormity caused by the simultaneous starting of the management program of the master control card and the management program of the standby control card can be solved.
And S340, enabling master-slave synchronization through the command line.
Specifically, the master-slave synchronization can be enabled through a command line corresponding to the master-slave synchronization, so that the master-slave synchronization is performed between the master database and the slave database.
And S350, checking the master-slave status, the configuration information and the operation and maintenance data of the current system through a command line.
