Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
Fig. 3 is refer to, a kind of implementation stream of the dual control storage device master/standby control method provided by the embodiment of the present invention
Cheng Tu.This method may comprise steps of：
S301：During being monitored to the working condition of master controller, determine whether master controller exception occurs.
In embodiments of the present invention, microcontroller is connected with master controller and preparation controller respectively by bus, by total
Line can carry out information transfer.Microcontroller is by monitoring the working condition of master controller, it may be determined that whether master controller goes out
It is now abnormal.
In a kind of embodiment of the present invention, step S301 may comprise steps of：
Step one：During being monitored to the working condition of master controller, according to the setting period 1 to main control
Device sends major state detection signal；
Step 2：If do not receive master controller return in setting first time period detects letter for major state
Number master control feedback signal, it is determined that master controller occurs abnormal.
For ease of description, above-mentioned two step is combined and illustrated.
In actual applications, the period 1 can be preset, microcontroller is according to the period 1 periodically to master control
Device processed sends major state detection signal, is monitored with the working condition to master controller.Certainly, microcontroller is to master control
During the working condition of device processed is monitored, working condition that can be simultaneously to preparation controller is periodically monitored.
If master controller is currently at normal operating conditions, master controller is received after major state detection signal,
The master control feedback signal that signal is detected for the major state can be returned to microcontroller.If master controller is currently at different
Normal state, then it possibly can not receive major state detection signal, or be returned without normal direction microcontroller for the master control shape
State detects the master control feedback signal of signal.One process of isolated operation major state detection signal can be carried out in master controller
Reception and master control feedback signal transmission.
If microcontroller does not receive master control feedback signal in first time period, it can determine that master controller occurs
It is abnormal.
It should be noted that period 1 and first time period default setting or can be set by the user, the present invention is real
Apply example without limitation.Such as, user can be according to actual conditions, the model of such as master controller, in concrete application circuit
Time that feedback signal is usually required etc. is received, first time period is specifically set.
In another embodiment of the present invention, step S301 may comprise steps of：
First step：During being monitored to the working condition of master controller, master controller is received according to setting
The status signal that second round sends；
Second step：If not receiving status signal in setting second time period, it is determined that master controller occurs
It is abnormal.
For ease of description, above-mentioned two step is combined and illustrated.
In actual applications, second round can be preset, master controller is according to second round on one's own initiative to microcontroller
Device sends status signal.One process of isolated operation the transmission of status signal can be carried out in master controller.
If microcontroller does not receive the status signal of master controller transmission in second time period, master can be determined
Controller occurs abnormal.
It should be noted that second round and second time period default setting or can be set by the user, the present invention is real
Apply example without limitation.Such as, user can be according to actual conditions, the model of such as master controller, in concrete application circuit
Time that feedback signal is usually required etc. is received, second time period is specifically set.
After microcontroller determines that exception occurs in master controller, step S302 operation can be performed.
S302：Active and standby conversion command is sent to preparation controller, so that preparation controller upgrades to master controller.
When microcontroller determines that master controller occurs abnormal, active and standby conversion command, standby control can be sent to preparation controller
Device is received after active and standby conversion command, and itself is escalated into master controller, to take over the work of former master controller.Specifically,
Can in preparation controller one process of isolated operation, after it receives active and standby conversion command, the corresponding upgrading behaviour of triggering
Make.

Controller and preparation controller connection, during being monitored to the working condition of master controller, determine whether master controller goes out
It is now abnormal, if it is, active and standby conversion command is sent to preparation controller, so that preparation controller upgrades to master controller.By dividing
The microcontroller not being connected with master controller and preparation controller completes active and standby control, due to microcontroller and master controller and standby control
It is connected between device processed by bus, rather than by network connection, so, it is possible to prevente effectively from because of reasons pair such as unstable networks
The working condition of master controller is judged by accident, and causes preparation controller to escalate into master controller, and is mutually disaccorded with former master controller
With the problem of occur, improve the systematic function of dual control storage device.
In one embodiment of the invention, when it is determined that master controller occurs abnormal, before step S302, also wrap
Include：
Step one：Standby control state detection signal is sent to preparation controller；
Step 2：If receiving the standby control feedback signal for being directed to standby control state detection signal of preparation controller return,
The step of performing to preparation controller transmission active and standby conversion command.
When microcontroller determines that master controller occurs abnormal, standby control state detection signal can be sent to preparation controller, with
Determine whether preparation controller is in normal operating conditions.
If microcontroller receives preparation controller and is directed to the standby control feedback signal that standby control state detection signal is returned, can
To determine that preparation controller is currently at normal operating conditions, active and standby conversion command can be sent to preparation controller, so that standby control
Device upgrades to master controller.
After microcontroller sends standby control state detection signal to preparation controller, if microcontroller is when setting the 3rd
Between standby control feedback signal is not received in section, then show that preparation controller currently may be abnormal, can be with outputting alarm prompt information, such as
Exported in pop-up mode, to point out the master controller and preparation controller of the current dual control storage device of user to there is abnormal, user
Problem investigation can be carried out in time according to the alarm prompt.
It should be noted that the 3rd period can be set and be adjusted according to actual conditions, the embodiment of the present invention pair
This is not limited.
