Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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.
Fig. 1 is a schematic flow diagram of a system fault recovery method provided in an embodiment of the present application, where the method is applied to a first board in an intelligent device, where the intelligent device includes at least two boards, and the first board is any one board in the intelligent device.
Specifically, the method comprises the following steps:
s101: and after the second board card is determined to have the system fault, broadcasting fault information of the second board card having the system fault.
Wherein, the second board card is: the intelligent device comprises a board card except the first board card.
In an implementation manner of the present application, it may be determined whether the second board card has a system fault in the following manner: determining a target bus from buses of the intelligent equipment; sending fault detection information to the second board card through each target bus; monitoring whether a fault detection response from the second board card is not received through each target bus; if so, determining that the second board card has a system fault; if it is monitored that a fault detection response from the second board card is received through at least one of the target buses, it is indicated to a certain extent that the second board card has no system fault, so that it cannot be determined that the second board card has a system fault.
In this case, when the fault information of the system fault of the second board card is broadcasted, the fault information of the system fault of the second board card can be broadcasted through each target bus.
It is understood that multiple buses may be provided in the smart device, and in the embodiment of the present application, one or more buses may be selected from the multiple buses of the smart device according to the specific states of the various buses, so as to send the fault detection message to the second board. Preferably, two or more buses can be selected as the target bus, so that the second board card can be effectively prevented from failing to receive the fault detection message due to reasons such as data transmission delay and the like in the process of sending the fault detection message through one bus, the second board card can not feed back a fault detection response to the first board card, and the second board card is further misjudged to have a system fault.
In addition, the above fault detection message may be understood as: and the message is used for detecting whether the board card has system fault.
The fault detection response can be understood as: and the board A receives the fault detection message and then notifies the board B that the board A has no system fault, wherein the board B is a board which sends the fault detection message to the board A.
That is to say, if the board card a has no system fault, the board card a can normally receive the fault detection message sent by the board card B, and then feed back a fault detection response to the board card B; if the board card a has a system fault and the board card a cannot normally work, the board card a cannot receive the fault detection message sent by the board card B, or cannot respond to the fault detection message after receiving the fault detection message sent by the board card B, and further under the two conditions, the board card a cannot send a fault detection response to the board card B.
S102: under the condition that fault information of system faults of a second board card broadcasted by other board cards except the first board card in the intelligent equipment is received, whether the second board card can be used for carrying out system fault recovery on the second board card is judged, and if the second board card can be used for carrying out system fault recovery on the second board card, S103 is executed.
After the first board card determines that the second board card has the system fault, the second board card needs to be subjected to system fault recovery in order to ensure normal operation of the intelligent device. In the embodiment of the application, the mode that in the prior art, the maintenance personnel manually carry out system fault recovery on the fault board card is abandoned, and the board card without the system fault in the intelligent equipment is selected, namely, the board card in the normal state carries out system fault recovery on the fault board card. In view of this, the first board needs to determine whether the first board has the capability of performing system fault recovery on the second board, if so, the system fault recovery is performed on the second board, and if not, the first board gives up performing system fault recovery on the second board, and the other boards in the intelligent device perform system fault recovery on the second board.
The first board card is any board card in the intelligent device, that is, the system fault recovery method provided in the embodiment of the present application is applicable to any board card in the intelligent device, based on this, the first board card confirms whether the second board card has a system fault, and meanwhile, other board cards also confirm whether the second board card has a system fault, and when the other board cards determine that the second board card has a system fault, the same operation as the first board card may be adopted to broadcast fault information that the second board card has a system fault, so that the first board card may receive fault information that the second board card broadcast by the other board cards has a system fault.
In addition, in the process that the first board card confirms whether the second board card has the system fault or not, the second board card may be judged to have the system fault due to the communication delay and the like, thereby causing a determination error, in this embodiment, after the fault information of the system fault of the second board card broadcast by the other board cards is received, that is, other board cards also judge whether the second board card can be used for carrying out system fault recovery on the second board card after confirming that the second board card has system fault, therefore, the first board card does not determine whether to recover the system fault of the second board card only after the first board card confirms that the system fault of the second board card occurs, but jointly confirm whether the second board card has a system fault with other board cards, that is, whether the second board card has a system fault is jointly confirmed by the multiple board cards, so that the probability of misjudging the second board card to have the system fault can be effectively reduced.
In one implementation mode of the application, when judging whether the self can be used for carrying out system fault recovery on the second board card, the self-recommendation information of the self can be broadcasted, and the self-recommendation information broadcasted by other board cards is monitored; when self-recommendation information broadcasted by other board cards is monitored, whether the self-recommendation information can be used for carrying out system fault recovery on a second board card is judged according to the self-recommendation information and the received self-recommendation information; and when the self-recommendation information broadcast by other boards is not monitored, determining that the self-energy can be used for performing system fault recovery on the second board.
Wherein, the self-referral information can be understood as: one board card in the intelligent equipment recommends information for performing system fault recovery on a fault board card in the intelligent equipment to other board cards. Specifically, the self-referral information may include: the present application is only described with reference to the information such as CPU occupancy and service scenario, and the specific content included in the self-referral information is not limited.
Specifically, when the first board card judges whether the first board card can be used for performing system fault recovery on the second board card according to self-recommendation information and received self-recommendation information, the priority between the first board card and each board card corresponding to the received self-recommendation information can be determined according to the self-recommendation information and the received self-recommendation information, then whether the board card with the highest priority is the first board card itself is judged, if so, the first board card is determined to be used for performing system fault recovery on the second board card, and if not, the system fault recovery on the second board card is abandoned.
For example, the priority between the first board and each board corresponding to the received self-referral information may be determined in such a manner that the lower the CPU occupancy, the higher the priority, and the like.
In an implementation manner of the application, before broadcasting self-recommendation information, hardware state information of the user can be obtained, and whether the hardware state information meets a first self-recommendation condition is judged; if the first self-recommendation condition is met, obtaining a self-service scene; judging whether the self service scene meets a second self-recommendation condition; and if the second self-referral condition is met, executing the step of broadcasting self-referral information of the self-referral information.
Specifically, the hardware state information may include: CPU occupancy, memory occupancy, and the like.
The first self-recommendation condition is a condition related to hardware status information, and may be different according to different hardware status information, for example, when the hardware status information includes a CPU occupancy rate, if the CPU occupancy rate is high, it indicates that the board is in a busy state, there may not be enough resources to perform system failure recovery on the failed board, and in this case, the system failure recovery on the failed board may be abandoned, and the self-recommendation information is not broadcast; on the contrary, if the CPU occupancy rate is low, it indicates that the idle resources in the board card are relatively abundant, and there may be enough resources to perform system failure recovery on the failed board card, and under this condition, it may recommend itself to other board cards in the intelligent device to see whether it can perform system failure recovery on the failed board card. In view of the above, the first self-recommended condition may be: the CPU occupancy is less than a preset value, e.g., 40%, etc.
The second self-recommended condition is a condition related to a business scenario. It can be understood that the overall demands on resources are different in different service scenarios, and the overall demands on resources are higher in some service scenarios, and in this case, in order to ensure normal execution of the service, sufficient resources may not be provided to perform system fault recovery on the failed board card, and in this case, it may not be recommended to other board cards in the intelligent device to perform system fault recovery on the failed board card; in addition, the overall demand of some service scenarios on resources is low, and under such a situation, sufficient resources may be provided to perform system fault recovery on the failed board, and system fault recovery on the failed board may be recommended to other boards in the intelligent device. In view of the above, the second self-recommended condition may be: the service scene is a preset service scene, and the like.
S103: and recovering the system fault of the second board card.
The method for performing system failure recovery on the second board may be influenced by the type of the system on the second board, and specific details may refer to the methods provided in the embodiments shown in fig. 3 to fig. 5, which are not described in detail herein.
As can be seen from the above, in the solutions provided in the above embodiments, the multiple board cards in the intelligent device cooperate to determine whether a certain board card in the intelligent device has a system fault, and when it is determined that the certain board card has the system fault, one board card in the intelligent device that has no system fault performs fault recovery on the faulty board card. Therefore, when the scheme provided by each embodiment is applied to fault recovery, manual operation of maintenance personnel is not needed, operation of the board in system fault recovery is simplified, and further fault recovery efficiency is improved.
The following describes a system failure recovery method provided in an embodiment of the present application by using a specific embodiment, and referring to fig. 2, a schematic flow diagram of another system failure recovery method is provided, where the method is applied to a first board in an intelligent device, and includes:

S207: and obtaining the self service scene.
S208: and judging whether the self service scene meets the second self-recommendation condition, and if so, executing S209.

Before the system fault recovery is carried out on the second board card, the user can be prompted to carry out the system fault recovery on the second board card, under the condition, if the user agrees to carry out the system fault recovery on the second board card, the S103 step is executed to carry out the system fault recovery on the second board card, if the user disagrees to carry out the system fault recovery on the second board card, the system fault recovery on the second board card can be postponed, the system fault recovery can be carried out on the fault board card by taking the user' S will into account, and the user experience can be greatly improved.
Specifically, the fault recovery prompt message may be a voice-type system fault recovery prompt message, or may also be a text-type or graphic-type system fault recovery prompt message, which is not limited in the present application.
When the fault recovery prompt message is a voice-type system fault recovery prompt message, the first board card sends the system fault recovery prompt message, the system fault recovery prompt message can be sent to a voice processing module in the intelligent device, the voice processing module plays the system fault recovery prompt message for a user, in addition, the voice processing module can obtain voice response of the user, and sends a processing result to the first board card after voice recognition and other processing are carried out on the voice response, and then the first board card obtains response information of the user aiming at the system fault recovery prompt message.
When the system fault recovery prompt message is in the form of characters, graphs and the like, the first board card sends the system fault recovery prompt message, the system fault recovery prompt message can be sent to an interface display module in the intelligent device, the interface display module displays the system fault recovery prompt message for a user, in addition, the interface display module can obtain a response input by the user, the response input by the user is sent to the first board card, and then the first board card obtains the response message of the user for the system fault recovery prompt message.
Specifically, whether the user agrees to perform system failure recovery may be determined according to at least one of the following information:
the user responds to the voice system failure recovery prompt message;
and the user responds to the system fault recovery prompt information in the forms of characters, graphs and the like.
