After detecting the bus current of input power by above-mentioned current detection module 110, control module 120 is according to mother
Line current value calculates the power consumption of lighting load, and the calculation formula for calculating the power consumption of lighting load is busbar voltage *
Lighting load current (bus current) * lighting load power factor * times are previously stored with illumination in the control module 120
Power consumption value when load normal work in preset time.When lighting load comes into operation it is middle when, it is negative to calculate illumination in real time
Current power consumption is carried, and is compared with pre-stored power consumption value, if the value of its difference exceeds a preset range
When, then it is assumed that lighting load is in abnormal state (i.e. malfunction).
At this point, by the first power switch circuit 136 in 120 the first Redundanter schalter of real-time control module 130 of control module
To the driving voltage (i.e. the output voltage of the first power switch circuit 136) that lighting load applies, it is, opening the first power
Powered-down road 136 carries out the reduction control of duty ratio, if lighting load works normally, the control of the first power switch circuit 136
The voltage that bright load applies only is controlled by advance illuminance setting value, and illuminance setting value is big, then driving voltage is also big,
Conversely, illuminance setting value is small, driving voltage is also small；If lighting load irregular working, that is, it is in malfunction, then is controlled
Module 120 controls the driving voltage that the first power switch circuit 136 applies according to preset strategy, that is, first quickly reduces the first work(
The driving voltage of rate switching circuit 136, and compare simultaneously reduce during the variation of current consumption current value of lighting load be
It is no to meet lighting load current consumption characteristics curve, if met, you can think that current lighting load is still controllable, then can maintain
Lighting load works in a suitable current value range, if do not met, especially the current value of lighting load compared with
Greatly, then it is assumed that lighting load has danger out of control at present, can further decrease the driving voltage of the first power switch circuit 136, very
It extremely can thoroughly disconnect the connection of the first Redundanter schalter module 130 and lighting load.Control module 120 controls the first power switch
The duty ratio of the angle of flow of circuit 136 is zero, if after the disconnection of the first Redundanter schalter module 130, lighting load also has electric current quilt
It detects, then it is assumed that the first Redundanter schalter module 130 has been damaged, and control at once is cut off by the first excision switching circuit 134
The first Redundanter schalter module 130, the second Redundanter schalter module 140 is come into operation, while control module 120 can pass through communication
Module 150 controls alarm module 160 and sends out failure alarm signal.
If the consumption electric current of corresponding lighting load is still abnormal, controls and closes the first Redundanter schalter module 130,
At this time if electric current reverts to zero, judge that the first Redundanter schalter module 130 is normal, failure is caused by lighting load circuit
, then every certain safe cooling time, restart again, soft starting mode is used when restarting, is slowly increased lighting load
Supply voltage cuts off the power supply of lighting load, realizing after repeatedly restarting still cannot restore normal immediately once discovery is abnormal
Working condition then has alarm module 160 to send a warning message, staff is notified to repair.
So the utility model embodiment can detect the running current of lighting load in real time, and by Redundanter schalter
The driving voltage that mould power switch circuit in the block applies carries out real-time control, to adjust output power in real time, keeps illumination negative
Load can be in normal operating conditions constantly in the process of running, if a certain path switching circuit damages, can automatically switch to another
Path switching circuit greatly improves the reliability of self-diagnosable and the illumination control apparatus 100 of Redundant Control, when extending overhaul
Between, further, the self-diagnosable of the utility model and the 100 energy fault self-diagnosis of illumination control apparatus of Redundant Control have event
Hinder automatic recovery ability, and can issue warning signal, improves the intelligence of self-diagnosable and the illumination control apparatus 100 of Redundant Control
Change horizontal.
Wherein, when using soft start, the detection abnormal method of lighting load is as follows：Software introduces artificial intelligence control
Method, real-time sampling usually the corresponding current value of some time axis during normal activation state and are stored in control module
In 120 storage unit, start time-current chracteristic curve, the current time current curve number started every time later for building
It is compared according to the data in storage unit, current value is abnormal when finding to start, and especially current value is bigger than normal, increase in current rate
When beyond the normal value stored in storage unit, then it is assumed that lighting load is abnormal.
The self-diagnosable and the illumination control apparatus 100 of the Redundant Control reliability of itself, drop are greatly improved as a result,
The failure rate of low self-diagnosable and the illumination control apparatus 100 of Redundant Control, delays the service intervals time, and can be more
A self-diagnosable and the illumination control apparatus of Redundant Control 100 wait for overhaul together, without influencing normal use.
In conclusion the utility model embodiment provides a kind of illumination control apparatus of self-diagnosable and Redundant Control, institute
