Brief description of the drawings
Fig. 1 is the schematic diagram of control device embodiment one of the present invention；
Fig. 2 is the schematic diagram of control device embodiment two of the present invention.
Embodiment
Below by drawings and examples, technical scheme is described in further detail.
Fig. 1 is the schematic diagram of control device embodiment one of the present invention, as illustrated, the device of the present embodiment includes：Remote control
Device 11, infrared transponder 12, electric supply installation 13 and processor 14.The remote control 11 passes through signal with infrared transponder 12
Connection, the electric supply installation 13 and processor 14 are electrically connected.The device of the present embodiment is used to carry out unlatching control to smart machine
Operation.
Remote control 11 is used to send open command, specifically, the purpose that remote control 11 sends open command is desirable to
Control device for opening is opened, under different use states, different settings is carried out to open command, such as this can be opened
Open instruction and be set to real-time open command, it can also be provided that reservation open command, when being set to real-time open command, remote control dress
Put 11 to send after open command, control device for opening is to open；When being set to reservation open command, remote control 11 need to send one
The individual open command for including time delay command, can just be opened to the period control device for opening specified.
Infrared transponder 12 is used for the open command for receiving the transmission of remote control 11, and according to the open command to quilt
Actuation means send opening control signal, are the first moment at the time of sending the opening control signal；
Specifically, when user has the demand for opening certain smart machine, such as opening intelligent refrigerator, first being filled using remote control
Put 11 and send open command, incited somebody to action in order that refrigerator can receive the open command, it is necessary to first pass through an infrared transponder 12
The open command is converted to opening control signal, and the opening control signal is the infrared signal of certain frequency range wavelength, such ability
The opening control signal is identified so that being specifically steered device, for example, can only make refrigerator that it is identified.When
When target actuation means change, opening control signal also changes its frequency range and wavelength, the unlatching of such as refrigerator accordingly
Control signal is different from the opening control signal of computer.Infrared transponder 12 sends opening control signal to being steered device,
In order to be able to embody open after curent change, just will send opening control signal at the time of be set to for the first moment, in order to
The electric current that device is steered during unlatching is compared.
Electric supply installation 13 is powered for being steered device for described in, and the electric supply installation 13 also includes current detector, institute
The supply current that current detector is used to detect the electric supply installation 13 is stated, the supply current before first moment is first
Supply current, the supply current after first moment is the second supply current.
When infrared transponder 12 is to being steered after device transmission opening control signal, it is steered device and is possible to just normally opened
Open, it is also possible to be not turned on.Due to the limitation of infrared protocol, can not generally judge whether it is normally-open, and in this implementation
In example, if normally-open to be the change by supply current to be judged.
One of effect of electric supply installation 13 is powered to be steered device, and another effect is to supplying using current detector
Electric current is monitored in real time, and the supply current that current detector is detected before opening control signal is sent is the first power supply
Electric current, and it is the second supply current to send the supply current after opening control signal, supply current detector detects first
After supply current and the second supply current, by the first supply current and the second supply current be sent to processor 14 carry out it is follow-up
Judgement is handled.
In addition, it is many for 13 pairs of detection modes for being steered device supply current of electric supply installation, for example：
Mode one, whole monitoring in real time, that is, no matter when, as long as electricity will enter to supply current on electric supply installation 13
Row is monitored and real-time report in real time；
Mode two, control detection, that is to say, that when opening control signal is not received by, without supply current
Detection, just current detecting is powered when only have received control instruction to being steered device；
Specifically, in the case of mode two, remote control 11 sends open command to infrared transponder 12, infrared forwarding
Open command is converted to opening control signal by device 12 again, and sends to electric supply installation 13 and be steered dress opening control signal
Put, electric supply installation 13 receives and carries out current detecting to being steered device after opening control signal, and the electric current detected is believed
Number processor 14 is sent to, Treatment Analysis is carried out to supply current by processor 14.
Processor 14 is used to judge first supply current and the second supply current, when the second supply current is big
When the difference of the first supply current, and the second supply current and the first supply current is not less than default power supply threshold value, then
Device unlatching is steered described in judging；Otherwise it is steered device described in judging to be not turned on, it is described that processor 14 is additionally operable to inquiry
First transmission times of opening control signal, the transmission times of the opening control signal is the first transmission times, if institute
When stating the first transmission times and being not more than transmission times threshold value, infrared transponder 12 continues to send opening control signal.
If specifically, being steered after device opens successfully, electric current can be than having substantially before being not turned under normal circumstances
Amplification；Therefore the processor 1414 is received after the first supply current and the second supply current, and it is judged, when the
When two supply currents are more than the first supply current, and just think to open successfully when more than default power supply threshold value.Reason is,
Supply current might have various disturbances, so as to cause electric current not to be unusual stable, it is more likely that erroneous judgement occur, because logical
The amplitude of normal current disturbing will not be very big, and be steered the supply current occurred after device is powered difference would generally than larger,
Therefore power supply threshold value is set, in order to reduce erroneous judgement.
If be steered after device opens successfully, electric current can be than having obvious amplification before being not turned on；Therefore the place
Reason device 14 is received after the first supply current and the second supply current, and it is judged, when the second supply current is more than first
During supply current, it is believed that open successfully.
Due to the change of electric current, for example become may well the disturbance of electric current cause, rather than to be steered device genuine
It is unlocked；And due to the usual amplitude of variation of the disturbance of electric current less, and be steered device it is normally-open when curent change meeting
Than larger, it is possible to set a power supply threshold value, when the difference of the second supply current and the first supply current is not less than the power supply
During threshold value, just assert and open successfully.
Opposite, if the difference of the second supply current and the first supply current is less than power supply threshold value, it is judged as other electricity
Flow disturbance, rather than be steered device and be unlocked, therefore be judged as being steered device not normally-open.Normally-open situation
Under, the second supply current should be in certain codomain, be preset when the difference of the second supply current and the first supply current is less than
During threshold value of powering, it can assert that the second supply current is less than lower limit, or the first supply current is higher than normal value, both of which
Belong to abnormal, can assert that being steered device is not turned on.
Because being not that remote control 11 is sent after open signal each time, processor 14 can obtain data-signal and
Subsequent treatment signal is generated, when this happens, it is understood that there may be signal transmission/reception failure or equipment fault, is caused
Result have following several：
Processor 14 generates subsequent treatment signal, but can not be expressed；
Processor 14 does not receive the signal of electric supply installation 13；
Electric supply installation 13 does not receive the opening control signal of infrared transponder 12；
Infrared transponder 12 fails to send opening control signal；
Remote control 11 fails to send open command；
Case above can independently occur, and can also combine generation, but either independent generation or joint occur, and all deposit
In the situation of signal transmission/reception failure or equipment fault, therefore when remote control 11 sends open command, but processor
14 when not generating any subsequent treatment signal, it is believed that is equipment fault.
It is not that each opening control signal can successfully open and be steered device due to a variety of causes, therefore to understand
Certainly above mentioned problem, is then provided with one the step of opening control signal is sent again after opening failure, due to most
Contingencies, need to only be repeated to send the problem of opening control signal can solve to open failure several times, therefore setting first is sent
Number of times and transmission times threshold value, are steered device and often open failure once, the first transmission times is Jia 1, opened when being steered device
Open failure and when the first transmission times is not more than transmission times threshold value, repeat infrared transponder 12 send opening control signal and it
Step afterwards.
More refinement ground regulation, the transmission times threshold value that the infrared transponder 12 sends opening control signal is 3.It is distant every time
When control device 11 sends open command, the first transmission times all restarts to count, and each remote control 11 sends open command,
Infrared transponder 12 can send 3 times unlatching control information, when open control information send 3 times after, no matter successfully open with
No, the open command for being all considered as this remote control 11 terminates.
The processor 14 is additionally operable to, when the first transmission times is more than transmission times threshold value, notify infrared transponder 12 to stop
Only send opening control signal.Opening failed scope includes, and is steered device and does not receive opening control signal, is steered
Device receives opening control signal and but opened unsuccessfully etc..In general, repeat to send 3 opening control signals, it is possible to
Success unlatching is steered device, simple to carry out trial unlatching if needing to carry out the situation or various failures of manual intervention
Good effect can not also be played by being steered device, therefore the transmission times threshold value is set as into 3, when first transmission times
Unlatching, which is then ceased attempt to, during more than transmission times threshold value is steered device.
Further, the processor 14 is additionally operable to the generation when the first transmission times is more than transmission times threshold value and opens control
Failure information processed, and send unlatching control failure information to host computer.When first transmission times is more than transmission times threshold value, processing
Control failure information is opened in the generation of device 14, and unlatching control failure information is sent into host computer progress subsequent treatment, upper
Machine is received after unlatching control failure information, can manually be operated and either be overhauled or carried out unlatching failure cause
Analysis, understands the concrete reason for opening failure, can also send and be again turned on instruction, and remote control 11 sends unlatching and referred to again
Order, infrared transponder 12 is again converted to open command the flow after opening control signal and progress.If can only be manual
Send opening control signal, just occur do not know open failure, and for a long time after can just send the situation of open command again.
The processor 14 is additionally operable to be steered after device successfully opens, and the first transmission times is reset.In order to not right
Subsequent operation is impacted, after being steered device and successfully opening, and the first transmission times is reset.No matter infrared transponder 12 first
The secondary unlatching control information that sends is switched on successfully or sent for second opening control information, sending open control information for the third time
Just open successfully, opened successfully as long as being steered device, the first transmission times just stops counting and resetting.
When each remote control 11 sends open command, the first transmission times all restarts to count, each remote control
11 send open command, and infrared transponder 12 can send 3 unlatching control information, after unlatching control information is sent 3 times,
No matter successfully whether open, the open command for being all considered as this remote control 11 terminates, the first transmission times is all reset.
Further, the processor 14 is additionally operable to when the difference of second supply current and the first supply current is less than in advance
If when threshold value of powering, being then steered device described in judgement and being not turned on.When infrared transponder 12 is sent to device is steered
After opening control signal, it is steered device and is possible to normally-open, it is also possible to be not turned on.Due to the limit of infrared protocol
System, can not generally judge whether it is normally-open, and in the present embodiment, if it is normally-open be by the change of supply current come
Judged, the supply current of the electric supply installation 13 before opening control signal is sent is the first supply current, and is sent
Supply current after opening control signal is the second supply current.If be steered after device opens successfully, electric current can be than not having
Having before unlatching has obvious amplification；Therefore the processor 14 is received after the first supply current and the second supply current, right
It is judged, when the second supply current is more than the first supply current, it is believed that open successfully.Alternatively, because the change of electric current
Change, for example become may well the disturbance of electric current cause, rather than be steered device and be really unlocked；And disturbing due to electric current
Move usual amplitude of variation less, and be steered equipment it is normally-open when curent change can be than larger, it is possible to set one
Individual power supply threshold value, when the difference of the second supply current and the first supply current is not less than the power supply threshold value, just assert and opens successfully.
Opposite, if the difference of the second supply current and the first supply current is less than power supply threshold value, it is judged as other electricity
Flow disturbance, rather than be steered equipment and be unlocked, therefore be judged as being steered equipment not normally-open.Normally-open situation
Under, the second supply current should be in certain codomain, be preset when the difference of the second supply current and the first supply current is less than
During threshold value of powering, it can assert that the second supply current is less than lower limit, or the first supply current is higher than normal value, both of which
Belong to abnormal, can assert that being steered device is not turned on.
In addition, thering are a variety of situations to belong to the interference that curent change occurs, such as
1st, surge, because surge is possible to current change quantity than larger, but transformation period is extremely short, that is, is not belonging to be steered
Electrical equipment Normal on state；
2nd, other disturbance situations, are also a kind of unstable state, electric current is suddenly big or suddenly small, nor it is just normally opened to be steered electrical equipment
Open；
3rd, it is likely to be electric supply installation 13 and damages or be steered device damage, it is unstable curent change all occur, but
It is to change also above default power supply threshold value.
In the case of this is several, if according to the device of above-described embodiment, can also be judged as being steered electrical equipment just normally opened
Open, but it is true really not so.
Possible solution is because above-mentioned several situations it is maximum what is common is that, the second supply current is simultaneously unstable
It is fixed, it is unstable state, as long as therefore the judgement of one stable state of increase the problem of can just solve above-mentioned.
For example, when the difference of the second supply current and the first supply current is not less than default power supply threshold value, then judging institute
State and be steered the step of device is opened and specifically include：The processor 14 judges whether second supply current is stable state, such as
Really described second supply current is not to be steered device described in stable state then judges to be not turned on；When the described second power supply electricity
Stream is stable state, and second supply current and the first supply current difference not less than default power supply threshold value when, then
Device unlatching is steered described in judging.
That is, when the second supply current is not stable state, directly judge that being steered equipment is not turned on, it is not necessary to
The difference of the second supply current and the first supply current is judged again；Only when the second supply current is stable state, then to second
The difference of supply current and the first supply current is judged.When due to current disturbing, the second power supply electricity may also occurs
The difference of stream and the first supply current not less than default power supply threshold value situation, in order to prevent therefore judge by accident, judgement when
Wait, processor 14 first judges whether the second supply current is in stable state, if the second supply current is in unstable state, i.e. duration
It is shorter, then judge without next step, while thinking to open failure；If the second supply current is in stable state, next step is carried out
Judge, i.e., whether the difference of the second supply current and the first supply current is not less than default power supply threshold value, if eligible, then it is assumed that
Open successfully, otherwise open failure.
The processor 14 judges the step of whether second supply current is stable state specifically, in the first judgement time
In threshold value, the variable quantity of second supply current is less than default variable quantity, then it is assumed that second supply current is in stable state.
When the second supply current is unstable, i.e. current anomaly, its feature is usually to become big even abruptly increase electric current moment, but
Such case only continues the extremely short time (Millisecond), therefore can judge time threshold by setting one first, when at this
In time threshold, electric current can not be maintained in certain scope, then can determine that as current anomaly, when supply current is in unstable state
When, it may be possible to electric current is unstable, it is also possible to equipment fault, when the processor 14 judges that the second supply current is in unstable state,
Generate the abnormal electrical power supply information of electric supply installation 13 or described be steered device abnormal information.
Similarly, when the processor 14 judges that first supply current is in unstable state, it is also possible to which electric current is unstable
Either caused by equipment fault, so when the first supply current is in unstable state, should also generate current anomaly information or
The abnormal electrical power supply information of person's electric supply installation 13.

Device 21, infrared transponder 22, electric supply installation 23 and processor 24.The remote control 21 passes through signal with infrared transponder 22
Connection, the electric supply installation 23 and processor 24 are electrically connected.The device of the present embodiment is used to carry out closing control to smart machine
Operation.
Remote control 21 is used to send out code, specifically, the purpose that remote control 21 sends out code is desirable to
Shutoff control unit is closed, under different use states, different settings is carried out to out code, such as this can be closed
Close instruction and be set to real-time out code, it can also be provided that reservation out code, when being set to real-time out code, remote control dress
Put 21 to send after out code, shutoff control unit is to close；When being set to reservation out code, remote control 21 need to send one
The individual out code for including time delay command, can just be closed to the period shutoff control unit specified.
Infrared transponder 22 is used for the out code for receiving the transmission of remote control 21, and according to the out code to quilt
Actuation means send closing control signal, are the first moment at the time of sending the closing control signal；
Specifically, when user has the demand for opening certain smart machine, such as opening intelligent refrigerator, first being filled using remote control

Electric current is monitored in real time, and supply current detector is detected after the first supply current and the second supply current, and first is supplied
Electric current and the second supply current are sent to processor 24 and carry out follow-up judgement processing.
In addition, it is many for 23 pairs of detection modes for being steered device supply current of electric supply installation, for example：
Mode one, whole monitoring in real time, that is, no matter when, as long as electricity will enter to supply current on electric supply installation 23
Row is monitored and real-time report in real time；
Mode two, control detection, that is to say, that when closing control signal is not received by, without supply current
Detection, just current detecting is powered when only have received control instruction to being steered device；
Specifically, in the case of mode two, remote control 21 sends out code to infrared transponder 22, infrared forwarding
Out code is converted to close off control signal by device 22 again, and sends to electric supply installation 23 and be steered dress closing control signal
Put, electric supply installation 23 receives and carries out current detecting to being steered device after closing control signal, and the electric current detected is believed
Number processor 24 is sent to, Treatment Analysis is carried out to supply current by processor 24.
Processor 24 is used to judge first supply current and the second supply current, when the second supply current is small
When the difference of the first supply current, and the second supply current and the first supply current is not less than default power supply threshold value, then
Device closing is steered described in judging；Otherwise it is steered device described in judging to be not turned off, it is described that processor 24 is additionally operable to inquiry
First transmission times of closing control signal, the transmission times of the closing control signal is the first transmission times, if institute
When stating the first transmission times and being not more than transmission times threshold value, infrared transponder 22 continues to send closing control signal.
If be steered after device closes successfully, electric current can be than having obvious amount of decrease before being not turned off；Therefore the place
Reason device 24 is received after the first supply current and the second supply current, and it is judged, when the second supply current is less than first
During supply current, it is believed that close successfully.
Specifically, the processor 24 is received after the first supply current and the second supply current, it is judged, when
When second supply current is less than the first supply current, and just think to close successfully when more than default power supply threshold value.Reason
It is that supply current might have various disturbances, so as to cause electric current not to be unusual stable, it is more likely that erroneous judgement occur, because
Will not be very big for the amplitude of usual current disturbing, and the difference for being steered the supply current occurred after device is closed would generally compare
Greatly, therefore power supply threshold value is set, in order to avoid erroneous judgement.
Due to the change of electric current, for example become may well the disturbance of electric current cause, rather than to be steered device genuine
It is closed；And due to the usual amplitude of variation of the disturbance of electric current less, and curent change meeting when being steered device normal switching-off
Than larger, it is possible to set a power supply threshold value, when the difference of the second supply current and the first supply current is not less than the power supply
During threshold value, just assert and close successfully.
Opposite, if the difference of the second supply current and the first supply current is less than power supply threshold value, it is judged as other electricity
Flow disturbance, rather than be steered device and be closed, therefore it is judged as that being steered device does not have normal switching-off.Normal switching-off situation
Under, the second supply current should be in certain codomain, be preset when the difference of the second supply current and the first supply current is less than
During threshold value of powering, it can assert that the second supply current is higher than the upper limit, or the first supply current is less than normal value, both of which
Belong to abnormal, can assert that being steered device is not turned off.
Because being not that remote control 21 is sent after shutdown signal each time, processor 24 can obtain data-signal and
Subsequent treatment signal is generated, when this happens, it is understood that there may be signal transmission/reception failure or equipment fault, may
The situation of generation has following several：
Processor 24 generates subsequent treatment signal, but can not be expressed；
Processor 24 does not receive the signal of electric supply installation 23；
Electric supply installation 23 does not receive the closing control signal of infrared transponder 22；
Infrared transponder 22 fails to send closing control signal；
Remote control 21 fails to send out code；
Case above can independently occur, and can also combine generation, but either independent generation or joint occur, and all deposit
In the situation of signal transmission/reception failure or equipment fault, therefore when remote control 21 sends out code, but processor
24 when not generating any subsequent treatment signal, it is believed that is equipment fault.
It is not that each closing control signal can be successfully closed and be steered device due to a variety of causes, therefore to understand
Certainly above mentioned problem, the step of being then provided with one and send closing control signal again after Fail-closed, due to most
Contingencies, need to only be repeated to send the problem of closing control signal can solve Fail-closed several times, therefore setting first is sent
Number of times and transmission times threshold value, are steered the every Fail-closed of device once, the first transmission times is Jia 1, are closed when being steered device
Close failure and when the first transmission times is not more than transmission times threshold value, repeat infrared transponder 22 send closing control signal and it
Step afterwards.
More refinement ground regulation, the transmission times threshold value that the infrared transponder 22 sends closing control signal is 3.It is distant every time
When control device 21 sends out code, the first transmission times all restarts to count, and each remote control 21 sends out code,
Infrared transponder 22 can send 3 closing control information, when closing control information send 3 times after, no matter be successfully closed with
No, the out code for being all considered as this remote control 21 terminates.
The processor 24 is additionally operable to, when the first transmission times is more than transmission times threshold value, notify infrared transponder 22 to stop
Only send closing control signal.Closing failed scope includes, and is steered device and does not receive closing control signal, is steered
Device receives closing control signal but Fail-closed etc..In general, repeat to send 3 closing control signals, it is possible to
It is successfully closed and is steered device, it is simple to carry out trial closing if needing to carry out the situation or various failures of manual intervention
Good effect can not also be played by being steered device, therefore the transmission times threshold value is set as into 3, when first transmission times
Closing, which is then ceased attempt to, during more than transmission times threshold value is steered device.
Further, the processor 24 is additionally operable to the generation when the first transmission times is more than transmission times threshold value and closes control
Failure information processed, and send closing control failure information to host computer.When first transmission times is more than transmission times threshold value, processing
Device 24 generates closing control failure information, and the closing control failure information is sent into host computer progress subsequent treatment, upper
Machine is received after closing control failure information, can manually be operated and either be overhauled or carried out Fail-closed reason
Analysis, understands the concrete reason of Fail-closed, can also send and be again switched off instruction, and remote control 21 sends closing and referred to again
Out code is converted to close off the flow after control signal and progress by order, infrared transponder 22 again.If can only be manual
Send closing control signal, just occur and do not know Fail-closed, and for a long time after can just send the situation of out code again.
The processor 24 is additionally operable to be steered after device is successfully closed, and the first transmission times is reset.In order to not right
Subsequent operation is impacted, after being steered device and being successfully closed, and the first transmission times is reset.No matter infrared transponder 22 first
Secondary transmission closing control information is shut off successfully or sent for second closing control information, third time and sends closing control information
Just close successfully, closed successfully as long as being steered device, the first transmission times just stops counting and resetting.
When each remote control 21 sends out code, the first transmission times all restarts to count.Each remote control
21 send out code, and infrared transponder 22 can send 3 closing control information, after closing control information is sent 3 times,
No matter it whether is successfully closed, the out code for being all considered as this remote control 21 terminates, the first transmission times is all reset.
Further, the processor 24 is additionally operable to when the difference of second supply current and the first supply current is less than in advance
If when threshold value of powering, being then steered device described in judgement and being not turned off.When infrared transponder 22 is sent to device is steered
After closing control signal, it is steered device and is possible to normal switching-off, it is also possible to be not turned off.Due to the limit of infrared protocol
System, can not generally judge whether normal switching-off, and in the present embodiment, if normal switching-off be by the change of supply current come
Judged, the supply current of the electric supply installation 23 before closing control signal is sent is the first supply current, and is sent
Supply current after closing control signal is the second supply current.If be steered after device closes successfully, electric current can be than not having
Having before closing has obvious amount of decrease；Therefore the processor 24 is received after the first supply current and the second supply current, right
It is judged, when the second supply current is less than the first supply current, it is believed that close successfully.Alternatively, because the change of electric current
Change, for example become may well the disturbance of electric current cause, rather than be steered device and be really closed；And disturbing due to electric current
Move usual amplitude of variation less, and curent change can be than larger when being steered equipment normal switching-off, it is possible to set one
Individual power supply threshold value, when the difference of the second supply current and the first supply current is not less than the power supply threshold value, just assert and closes successfully.
Opposite, if the difference of the second supply current and the first supply current is less than power supply threshold value, it is judged as other electricity
Flow disturbance, rather than be steered equipment and be closed, therefore it is judged as that being steered equipment does not have normal switching-off.Normal switching-off situation
Under, the second supply current should be in certain codomain, be preset when the difference of the second supply current and the first supply current is less than
During threshold value of powering, it can assert that the second supply current is higher than the upper limit, or the first supply current is less than normal value, both of which
Belong to abnormal, can assert that being steered device is not turned off.
In addition, thering are a variety of situations to belong to the interference that curent change occurs, such as
1st, other disturbance situations, are also a kind of unstable state, electric current is suddenly big or suddenly small, are normally closed nor being steered electrical equipment
Close；
2nd, it is likely to be electric supply installation 23 and damages or be steered device damage, it is unstable curent change all occur, but
It is to change also above default power supply threshold value.
In the case of this is several, if according to the device of above-described embodiment, can also be judged as being steered electrical equipment and normally close
Close, but it is true really not so.
Possible solution is because above-mentioned several situations it is maximum what is common is that, the second supply current is simultaneously unstable
It is fixed, it is unstable state, as long as therefore the judgement of one stable state of increase the problem of can just solve above-mentioned.
For example, when the difference of the second supply current and the first supply current is not less than default power supply threshold value, then judging institute
State and be steered the step of device is closed and specifically include：The processor 24 judges whether second supply current is stable state, such as
Really described second supply current is not to be steered device described in stable state then judges to be not turned off；When the described second power supply electricity
Stream is stable state, and second supply current and the first supply current difference not less than default power supply threshold value when, then
Device closing is steered described in judging.
That is, when the second supply current is not stable state, directly judge that being steered equipment is not turned off, it is not necessary to
The difference of the second supply current and the first supply current is judged again；Only when the second supply current is stable state, then to second
The difference of supply current and the first supply current is judged.When due to current disturbing, the second power supply electricity may also occurs
The difference of stream and the first supply current not less than default power supply threshold value situation, in order to prevent therefore judge by accident, judgement when
Wait, processor 24 first judges whether the second supply current is in stable state, if the second supply current is in unstable state, i.e. duration
It is shorter, then judge without next step, while thinking Fail-closed；If the second supply current is in stable state, next step is carried out
Judge, i.e., whether the difference of the second supply current and the first supply current is not less than default power supply threshold value, if eligible, then it is assumed that
Close successfully, otherwise Fail-closed.
The processor 24 judges the step of whether second supply current is stable state specifically, in the first judgement time
In threshold value, the variable quantity of second supply current is less than default variable quantity, then it is assumed that second supply current is in stable state.
When the second supply current is unstable, i.e. current anomaly, its feature is usually to become big even abruptly increase electric current moment, but
Such case only continues the extremely short time (Millisecond), therefore can judge time threshold by setting one first, when at this
In time threshold, electric current can not be maintained in certain scope, then can determine that as current anomaly, when supply current is in unstable state
When, it may be possible to electric current is unstable, it is also possible to equipment fault, when the processor 24 judges that the second supply current is in unstable state,
Generate the abnormal electrical power supply information of electric supply installation 23 or described be steered device abnormal information.
Similarly, when the processor 24 judges that first supply current is in unstable state, it is also possible to which electric current is unstable
Either caused by equipment fault, so when the first supply current is in unstable state, should also generate current anomaly information or
The abnormal electrical power supply information of person's electric supply installation 23.
