Part, it is isolated when getting wherein any one power module failure, is occurred in any one group of output voltage unexpected
Shi Jinhang cutting, due to using modularized design, segregate power module or cut-off output voltage are on the whole not
It will affect the lighting condition of entire vehicle；User is to breaking down or unexpected module repairs processing or directly more at this time
It changes.
Further, the step S1 specifically:
S11, control module obtain the operating status of four power modules respectively, if the operation shape of only the first power module
State is malfunction, then first power module is isolated；
If S12, the only operating status of the first power module and second power supply module be malfunction, isolation described in
First power module and second power supply module, and issue the level-one dim signal for lowering LED light illumination；
If S13, the first power module, second power supply module and third power module operating status be failure shape
First power module, second power supply module and third power module is then isolated in state, and issues and lower LED light illumination
Second level dim signal, the LED light illumination that the second level dim signal is lowered are higher than the level-one dim signal.
As can be seen from the above description: it realizes to the control of the redundancy backup of power module, three or four power modules
Overall output power can guarantee that the illumination of entire vehicle uses, and only one or two power modules are to work normally
When, need to lower the required power that LED light illumination carrys out lower entire lighting system, to guarantee one or two power modules
Output power can also make the illumination of vehicle not extinguish, and effectively reduce light failure operation security problem caused by vehicle,
Security performance with higher.
Further, the step S2 specifically:
Control module obtains the line status of five groups of independent output voltages, if the wherein route of any one group of output voltage
State is the unexpected state of overload or short circuit or over-voltage, then line disconnection state is the output voltage of unexpected state.
As can be seen from the above description: it is independent 5 groups of routes that output voltage, which is divided into, by five groups of LED light on vehicle into
Row occurs overloading or when the unexpected state of short circuit or over-voltage, it is defeated to cut off the road respectively for electricity output in wherein any one group of route
Voltage out, so that corresponding LED light is extinguished, and other several groups then can still provide normal car lighting, so as to effective
Reduce light failure operation security problem caused by vehicle, security performance with higher.
Further, it further comprises the steps of:
S31, control module obtain current light-modulating mode, if the current light-modulating mode is mode with an automatic light meter, start
Light sensor simultaneously executes step S32, if the current light-modulating mode is hand-operating light mode, closes light sensor and holds
Row step S33；
S32, setting brightness value is obtained, receives the current illumination value of light sensor acquisition, according to current illumination value and set
Determine brightness value output lamps and lanterns adjustment signal, the output voltage that the lamps and lanterns adjustment signal is used to adjust lamps and lanterns makes current illumination value
Reach setting brightness value；
S33, setting PWM value is obtained, the output voltage of lamps and lanterns is adjusted according to the setting PWM value.
As can be seen from the above description: manual mode and automatic mode in a manual mode can be supported for the adjusting of LED light
The subjective feeling and riding comfort of passenger are improved, vehicle can be adjusted in real time according to current light intensity in automatic mode
Compartment illumination, to save energy consumption, under different service conditions, the present invention is energy saving on the basis of current lighting energy consumption
30%-50%.
Further, it further comprises the steps of:
Control module adopts the input voltage of power module, output voltage, internal temperature and output electric current in real time
Collection；
Control module acquires the output voltage and load current of output module in real time；
Control module acquires the operating current of output to light sensor in real time；
Control module compares collected real time data and preset normal data, if the comparing result
For abnormal condition, then send the abnormal condition to TCMS system so that TCMS system according to the abnormal condition into
Row early warning.
As can be seen from the above description, realizing Self-fault diagnosis detection, early warning can be started when finding failure, thus quickly
Repair processing.
