Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
In order to solve prior art problem, a kind of method of supplying power to and device is embodiments provided.
A kind of method of supplying power to for being provided to the embodiment of the present invention first below is introduced.
It should be noted that a kind of method of supplying power to that the embodiment of the present invention is provided is applied to the keyless entry of electric motor car
System, keyless access system include power supply and power supply backup system, are provided with multiple electrical equipments in electric motor car, wherein, should
Electrical equipment can be luminaire, instrument and instruction lamp apparatus or electronic auxiliary control appliance etc..
As shown in figure 1, a kind of method of supplying power to provided in an embodiment of the present invention, can include:
S101:The power supply signal that detection power supply is produced.
Typically in electric motor car, high voltage power supply converts voltages into the low tension that electric motor car is used by power supply changeover device
Source, then during electric motor car traveling, carries out normal power supply by the power supply after conversion to each electrical equipment in electric motor car,
To ensure the normal operation of each electrical equipment.
Therefore, in order to ensure the normal operation of each electrical equipment, detect that the power supply signal that power supply is produced is follow-up to carry out
Step, wherein, detects that the detection frequency of the power supply signal that power supply is produced can have various, the electricity that can be produced with real-time detection power supply
Source signal, it is also possible to detect the power supply signal that power supply is produced according to predeterminated frequency, this is all rational.
S102:Whether the power supply signal that judgement is detected is fault-signal, if it is, execution step S103, if not, not
Process.
After the power supply signal that detection power supply is produced, exported when the signal for exporting is with failure during due to power supply normal work
Signal is different, therefore, it can whether to determine power supply occur by judging the power supply signal for detecting if being whether fault-signal therefore
Barrier, and subsequent step is carried out according to judged result.
In one implementation, judge whether the power supply signal for detecting is fault-signal, can be included:
Whether the logical signal normally exported with power supply is consistent the power supply signal that judgement is detected, if do not met, it is determined that
For fault-signal.
Wherein, logical signal refer to, or, the signal of non-and combinations thereof.
For example:The logical signal that power supply is normally exported is " 1 ", and the power supply signal exported during power failure is " 0 ";
As the power supply signal for detecting is " 0 ", the logic that the power supply signal " 0 " for detecting normally is exported with power supply is judged
Signal " 1 " does not meet, it is determined that for fault-signal.
S103:Startup power supply standby system is powered to multiple electrical equipments.
When judged result is that the power supply signal for detecting is fault-signal, you can determine power failure, now open
Galvanic electricity Source backups system is powered to multiple electrical equipments, to ensure the normal operation of each electrical equipment.
In one implementation, startup power supply standby system is powered to multiple electrical equipments, can be included:
Send and start request to power supply backup system, so that power supply backup system is supplied to multiple electrical equipments respectively
Electricity.
When power supply does not break down, power supply backup system is electrically connected with each electrical equipment, when power failure,
Can send and start request to power supply backup system, after power supply backup system receives startup request, respectively multiple electricity consumptions be set
Standby to be powered, wherein, the specific embodiment being powered to electrical equipment is prior art, be will not be described here.
Compared with prior art, in the present invention, the power supply signal that power supply is produced is detected, judges that the power supply signal for detecting is
It is no for fault-signal, when the power supply signal for detecting is fault-signal, startup power supply standby system enters to multiple electrical equipments
Row power supply, thus, when power failure, just can startup power supply standby system be powered to multiple electrical equipments, it is ensured that
The normally travel of electric motor car, it is to avoid the generation of accident.
Understand for convenience, method shown in Fig. 1 is described in detail below by a specific embodiment:
For example:The power supply signal of power supply output is fault-signal;
The power supply signal that the keyless access system detection power supply of electric motor car is produced, whether the power supply signal that judgement is detected
For fault-signal, as the power supply signal of power supply output is fault-signal, therefore startup power supply standby system is set to multiple electricity consumptions
It is standby to be powered.
On the basis of method shown in Fig. 1, as shown in Fig. 2 a kind of method of supplying power to provided in an embodiment of the present invention, can be with
Including:
S104:The information that output is had been turned on comprising power supply backup system.
After startup power supply standby system is powered to multiple electrical equipments, in order that driver knows the situation, can
It is to export the information having been turned on comprising power supply backup system to point out driver to have been turned on power supply backup system, wherein, defeated
The mode for going out information has various, carries out citing introduction below:
First kind of way:Floating layer is shown in the middle control display screen upper strata top set of electric motor car, is shown comprising power supply in floating layer
The prompting message dialog box that standby system has been turned on;
The second way:The message having been turned on comprising power supply backup system is directly displayed on the middle control display screen of electric motor car
Reminder dialog frame;
The third mode:The information that output is had been turned on comprising power supply backup system in the form of speech.
Thus, after startup power supply standby system is powered to multiple electrical equipments, in the way of exporting information
Driver is made to know the situation, so that driver makes corresponding operation.
On the basis of method shown in Fig. 1, as shown in figure 3, a kind of method of supplying power to provided in an embodiment of the present invention, can be with
Including:
S105:When detecting power supply and producing predetermined fault recovery signal, carried out to multiple electrical equipments by power supply
Power, and stop power supply backup system and be powered to multiple electrical equipments.
Due to power supply it some times happens that recoverable failure, after Failure elimination, you can continue to multiple electrical equipments to enter
Row power supply, therefore, when detecting power supply and producing predetermined fault recovery signal, you can will be powered to multiple electrical equipments
Power supply backup system switch to power supply, be powered to multiple electrical equipments by power supply, and stop power supply backup system to
Multiple electrical equipments are powered.
Wherein, the predetermined fault recovery signal can be power supply Restart Signal or power supply useful signal etc..
Thus, after power up is normal, continue through power supply and be powered to multiple electrical equipments, and it is standby to stop power supply
