Alternatively, the controller mainboard of the embodiment of the present invention further includes memory, for storage circuit state, to remember
The peripheral circuit of failure and corresponding stand-by circuit, in order to subsequently start shooting in use, directly reading the circuit state
Determine whether to start stand-by circuit.
The embodiment of the invention discloses a kind of electrical equipment, including controller mainboard provided in an embodiment of the present invention.
The embodiment of the present invention additionally provides a kind of circuit control method, which can be used for implementation of the present invention
Controller mainboard described in example, is performed by the control unit of controller mainboard or other units of electrical equipment.
As shown in figure 3, the circuit control method includes：
Whether step S301, the peripheral circuit of detection control unit break down.
Fault detect of the present invention, can be the self-test carried out before electrical equipment system is not opened.
Step S302, when detecting the peripheral circuit of failure, the peripheral circuit for judging to break down whether there is
Corresponding stand-by circuit, wherein, stand-by circuit has the function of identical with the peripheral circuit to break down.Occur being not detected by
During the peripheral circuit of failure, electrical equipment starting up can be controlled to work.On stand-by circuit and periphery electricity in the present embodiment
The description on road may refer to the above-mentioned introduction on controller mainboard, and which is not described herein again.
Step S303, when there are during corresponding stand-by circuit, control corresponding stand-by circuit to replace the periphery broken down
Circuit works.But when being not present, determine the system failure.
According to embodiments of the present invention, when some or certain several peripheral circuits break down in controller mainboard, make
The faulty circuit is replaced to work with stand-by circuit so that whole equipment system normal operation, without being replaced, reduces controller
Mainboard failure rate after sale, ensures the controller uptime, improves the reliability of device systems.
In order to avoid there is influence of the normal peripheral circuit of event to stand-by circuit, the embodiment of the present invention is corresponding standby in control
While the peripheral circuit to be broken down with circuitry instead is worked, further include：The peripheral circuit that control is broken down disconnects.
Specifically, the disconnection of the peripheral circuit to break down can be realized by controlling switch circuit, it is ensured that stand-by circuit substitutes failure
Peripheral circuit after work normally.
Alternatively, while the peripheral circuit for controlling corresponding stand-by circuit to replace breaking down is worked, may be used also
With including：Storage circuit state, wherein, the circuit state of storage is used to remembering the peripheral circuit that breaks down and corresponding standby
Use circuit.Can be by memory storage circuit state, in order in follow-up start, directly be read out, to determine to be
No unlatching stand-by circuit.
Another optional embodiment of the embodiment of the present invention as shown in figure 4, including：
Step S401, obtains the circuit state of storage.Can be deposited before being directly acquired after device systems initialization
The circuit state of storage.
Step S402, according to circuit state, it is determined whether to enable stand-by circuit.When determining that stand-by circuit need not be opened,
Perform step S403；When needing to open stand-by circuit, step S405 is performed.
Whether step S403, the peripheral circuit of detection control unit break down.
Step S404, when detecting the peripheral circuit of failure, the peripheral circuit for judging to break down whether there is
Corresponding stand-by circuit.When being not detected by the peripheral circuit of failure, electrical equipment starting up can be controlled to work.When
There are during corresponding stand-by circuit, step S405 is performed；When there is no during stand-by circuit, determining the system failure.
Step S405, controls the peripheral circuit that corresponding stand-by circuit replaces breaking down to work.At the same time it can also
The peripheral circuit that control is broken down disconnects, and opens corresponding stand-by circuit.Then step S403 can be returned again to, it is outer to realize
The real-time fault detection of circuit is enclosed, ensures system safe and stable operation.
Specifically, initialization process is carried out to device systems first, transfers memory function and obtain circuit state, it is determined whether
Stand-by circuit is had turned on, the peripheral circuit shielded if opening according to circuit state, opens stand-by circuit；Subsequently into being
Unite self-test, check that circuit whether there is problem, system is normally then started shooting work, if system judges the periphery there are failure
Circuit whether there is stand-by circuit, there is no the system failure is then judged, and if so, the peripheral circuit of shielding, starts standby electricity
Road, comes back to self-test while stores state at this time；Break down during system worked well, then same first failure judgement circuit is
It is no there are stand-by circuit, while repeat above procedure.
Obviously, the above embodiments are merely examples for clarifying the description, and the restriction not to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the application.
