As shown in FIG. 1, in this embodiment, a single-board active-standby control method includes:

S10. Obtain the hardware active / standby competition result of the local board and the peer board; S20. When the hardware active / standby competition result of the local board is the active board, send an inquiry message to the peer board; obtain The hardware status information of the opposite end board; S30. Determine the active and standby status of the local end board according to the hardware state information.

In this embodiment, the combination of hardware and software is used to determine the active and standby status of the board, especially when determining the active board, software will participate in the decision, avoiding the situation of dual active boards and improving the system's reliability.

In this embodiment, the local board (referred to as the board in the following description) and the peer board (referred to as the board in the following description) are both a communication interface board. In a communication system, the two are the master and the slave. Relationship, when one board is the active board and the other board is the standby board, the two boards can operate normally only with one master and one standby.

In this embodiment, the signals related to the active and standby of the board are: the final active and standby signals, and the hardware active and standby signals. The hardware consists of three main registers to participate in the software and hardware decision-making master-slave process: "software lock master-standby enable" register, "software lock master-standby" register, hardware master-standby register. The hardware writes the final master / standby information to the final master / standby signal according to whether the software lock master / standby enable register is software locked. That is, if the software does not lock the master and backup, the final value of the master and backup signals is determined by the hardware, and the final master and backup signals are equal to the hardware master and backup signals; if the software locks the master and backup, the value of the final master and backup signals is completely determined by the software. The master-slave information determined by the software is written into the "software lock master-slave" register, and finally the master-slave signal is equal to the value of this register.

In this embodiment, the single-board master-slave control method is applicable to the single-board startup process. First, after the single-board initialization is complete, the hardware master-standby competition is enabled; the software locks the master-standby enable, and the default board is the standby board. And participate in the hardware master-slave competition; when participating in the hardware master-slave competition, if the board's software is locked as a standby, its locked state will disappear, the steps are as follows: During the startup and switching process, if the board's software is locked as a standby, start Timer2, when the timer expires, get the hardware status of the board. If the board is the standby, disable the software to lock the master and standby, stop the timer timer2; if the board is the master, but there is no software to lock the master and standby, it will not be processed ; If the board is the master, and the software locks the master and slave enable, send a message to query the status of the board.

As shown in FIG. 1, in this embodiment, after obtaining the main-standby competition result of the local board and the opposite board further includes: S11. When the hardware main-standby competition result of the local board is the standby board To enable the software of the local board to lock the active and standby boards, set the local board as the standby board when the power is completed, and set the opposite board as the active board.

This embodiment is mainly to avoid the situation of dual active, and when the hardware main and standby competition result of the local board is the standby board, the situation that the local board and the opposite board compete for the active board will not occur, so there is no need for excessive To control the process, simply set the counter to the main board.

As shown in FIG. 2, in this embodiment, the step S20 includes: S21, sending a query message to the opposite board; S22, when the sending of the query message fails, enabling the software lock of the local board to the master Standby, set the local board as the active board when the power is completed, and set the peer board as the standby board; S23, when the query message is sent successfully, start the timer; S24, if in the timer The reply message of the peer board is not received within the preset period of time, enabling the software of the local board to lock the master and backup, setting the local board as the master board when the power is completed, and setting the peer board It is a standby board; S25. If the reply message of the peer board is received within the preset time period of the timer, the hardware status information of the peer board is obtained from the reply message.

In this embodiment, if the main hardware competition result of the board is the main, send a message to the board to query the board hardware status information. If the query message is sent several times in succession, the board software is disabled to lock the master and backup; if If the message is sent successfully, the timer timer1 is started to check whether the board has received a reply message to the board. If the response is received within the specified time and the timer1 is stopped, the process proceeds to step S30. Answer the message to the board, stop the timer timer1, and disable the software of the board to lock the active and standby.

In this embodiment, the hardware status information includes: the hardware status of the peer board, the power-on time of the peer board, and the slot number.

As shown in FIG. 3, in this embodiment, the step S30 includes: S31. When the hardware status of the peer board is the standby board or unknown, enable the software of the local board to lock the master and backup, and power on When finished, set the local board as the active board and the remote board as the standby board; S32. When the hardware status of the remote board is the active board, compare the remote board with the local board The power-on time of the board; S33. If the power-on time of the local board is earlier than the power-on time of the opposite board, enable the software of the local board to lock the master and backup, and then the local board when the power is completed Set as the active board, and set the opposite end board as the standby board; S34. If the power-on time of the local end board is later than the power-on time of the opposite end board, enable the software of the local end board to lock the active and standby boards. When the power-on is completed, set the local board as the standby board, and set the peer board as the master board; S35. If the power-on time of the local board is equal to the power-on time of the peer board, compare Slot number of the opposite end board and the local end board; S36. If the slot number of the local end board is smaller than the slot number of the opposite end board, enable the software of the local end board to lock the master and backup. When the power is completed, set the local board as the standby board, and set the opposite board as the main board; S37. If the slot number of the local board is greater than the slot number of the opposite board, enable the local board The software of the board locks the active and standby devices. When the power is completed, the local board is set as the active board, and the opposite board is set as the standby board.

In this embodiment, when the board receives the response message from the board, if the board hardware status is standby or unknown, the board software is disabled to lock the master and standby. If the hardware status of the board is the master, compare the power-on time of the two boards. If the power-on time of the board is early, disable the software to lock the master and backup. If the board is powered on late, continue to enable the software to lock the master and slave, and the software to lock the board as a standby. If the power-on time of the two boards is equal, compare the slot number of the board. If the slot of the board is small, disable the software lock master and slave; if the slot number of the board is large, continue to enable the software lock master and slave , The software locks the board for preparation.

Determines whether the local board is based on the hardware status information Perform the standby switchover.

In this embodiment, during the switchover between the active and standby states of the board, there is also an active-standby competition. When the active-standby is switched, if the software of the board locks the active-standby enable, the disable software locks the active-standby without any other steps. Therefore, in this embodiment, only the case of the backup-to-master is discussed, which is also to prevent the system from having dual master boards.

As shown in FIG. 5, in this embodiment, the step S50 includes: S51. When the hardware status of the peer board is the standby board or unknown, enable the software of the local board to lock the master and backup to perform the backup transfer Master switch, switch the local board to the main board, and set the peer board to the standby board; S52.
