To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In attached drawing, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall in the protection scope of this application.
Fig. 1 is please referred to, Fig. 1 is a kind of step flow chart of the monitoring method of multiple nucleus system provided herein, application
Starting core in multiple nucleus system, comprising:
Step 1: the first heartbeat frame is sent every other cores in the multiple nucleus system where the first preset time to starting core,
So that other cores return to acknowledgement frame after receiving the first heartbeat frame；
Specifically, being equipped with a starting core in each multiple nucleus system, starting core is independently reliable, can regularly send first
Heartbeat frame is to other cores in the multiple nucleus system where the starting core, it is to be understood that in multiple nucleus system, in addition to starting core
Other all kernels are referred to as other cores.Other cores are after receiving the first heartbeat frame, and return acknowledgement frame gives starting core, with table
Show that oneself is operated normally.
Step 2: receiving the acknowledgement frame of other cores return；
Step 3: the fault keranel for not returning to acknowledgement frame more than the first preset time is judged whether there is, if so, entering step
4；
Step 4: control fault keranel is restarted.
Specifically, starting core receives the acknowledgement frame returned by other cores, and judge whether there is more than the first preset time
Other cores of acknowledgement frame are not returned, are not returned to acknowledgement frame in the stipulated time and are shown that the kernel crashes, and determines it as fault keranel,
Specifically, assuming that starting core sends a first heartbeat frame to other cores every 5s, starting core sends the initial time of heartbeat frame
It can be set to the starting time of starting core, opened correspondingly, the first preset time in step 3 sends the first heartbeat frame from starting core
Beginning timing, if respectively 0s, 5s, 10s ... starts core in 5s by taking 5s as an example at the time of starting core sends the first heartbeat frame
When to other cores send heartbeat frame, the timing since 5s, if within 5s, i.e., within the period of 5s- 10s, depositing
In no other cores for returning to acknowledgement frame, then illustrate there is the kernel (i.e. fault keranel) to crash in multiple nucleus system, starts nuclear control
Fault keranel restarting, the mode of restarting specially control fault keranel, which re-executes, powers on process.
This application provides a kind of monitoring methods of multiple nucleus system, applied to the starting core in multiple nucleus system, comprising: every
Other cores in multiple nucleus system where from first preset time to starting core send the first heartbeat frame, so that other cores are receiving
Acknowledgement frame is returned after first heartbeat frame；Receive the acknowledgement frame of other cores return；It judges whether there is more than the first preset time not
Return to the fault keranel of acknowledgement frame；If so, control fault keranel is restarted.As it can be seen that in practical applications, using the scheme of the application, leading to
It crosses starting core and sends heartbeat frame to other cores, and judge whether to receive the acknowledgement frame of other cores return, do not return answer if it exists
The fault keranel of frame is answered, then soft reboot is carried out to fault keranel, to improve the robustness and reliability of multiple nucleus system, guarantees multicore system
The normal work of system.
On the basis of the above embodiments:
Embodiment as one preferred, the monitoring method further include:
The second heartbeat frame is sent to watchdog module every the second preset time, so that watchdog module is pre- more than second
If the time does not receive the second heartbeat frame, control starting core is restarted.
Specifically, the state of starting core itself is monitored by watchdog module, start core every the second preset time to seeing
Door dog module sends the second heartbeat frame, that is, feeds dog, if watchdog module is more than that the second preset time does not receive the second heartbeat frame,
Then determine that starting core crashes, watchdog module control starting core is restarted.
Embodiment as one preferred, the second preset time is less than the first preset time.
Specifically, in order to further increase the reliability of starting core, starting core sends the second heartbeat frame to watchdog module
Time interval should be less than starting core to other cores send the first heartbeat frame time interval, when start core crash when, Ke Yi
Quickly restart under watchdog module control, does not influence the information exchange for starting core and other cores.
Embodiment as one preferred judges whether there is after receiving the acknowledgement frame that other cores return more than first
Before preset time does not return to the fault keranel of acknowledgement frame, the monitoring method further include:
All acknowledgement frames received are verified, successful acknowledgement frame will be verified and be determined as correct frame；
Then judge whether there is the process for not returning to the fault keranel of acknowledgement frame more than the first preset time specifically:
Judge whether there is the fault keranel for not returning to correct frame more than the first preset time.
It is understood that other cores for not returning to acknowledgement frame at the appointed time are fault keranels, for further increasing
The considerations of multiple nucleus system reliability, the application also verify the acknowledgement frame returned in the stipulated time, specifically can be according to pre-
If content, the identity information etc. of agreement verification acknowledgement frame illustrate that the acknowledgement frame is not if acknowledgement frame is unsatisfactory for preset condition
Correct frame, other cores for further relating to return to the acknowledgement frame are fault keranel, and therefore, fault keranel includes the kernel for not returning to acknowledgement frame
And returning to the kernel of wrong responses frame, i.e., the kernel for not returning to correct frame is fault keranel, and starting core needs are restarted more than the
One preset time does not return to all fault keranels of correct frame, to guarantee the normal work of multiple nucleus system.
Referring to figure 2., Fig. 2 is a kind of structural schematic diagram of the monitoring system of multiple nucleus system provided herein, application
Starting core in multiple nucleus system, comprising:
First sending module 1 is sent for other cores where the first preset time to starting core in multiple nucleus system
First heartbeat frame, so that other cores return to acknowledgement frame after receiving the first heartbeat frame；
Receiving module 2, for receiving the acknowledgement frame of other cores return；
Judgment module 3, for judging whether there is the fault keranel for not returning to acknowledgement frame more than the first preset time, if so,
Module 4 is restarted in triggering；
Restart module 4, restarts for controlling fault keranel.
Embodiment as one preferred, the monitoring system further include:
Second sending module, for sending the second heartbeat frame to watchdog module every the second preset time, to guard the gate
Dog module when not receiving the second heartbeat frame more than the second preset time, restart by control starting core.
Embodiment as one preferred, the second preset time is less than the first preset time.
Embodiment as one preferred, the monitoring system further include:
Correction verification module will verify successful acknowledgement frame determination and be positive for verifying to all acknowledgement frames received
True frame；
Then judgment module 3 is specifically used for:
