Description
Technical field
The invention belongs to field of automobile, specially refer to the relevant apparatus of the LED steering indicating light of automobile.
Background technology
The LED lamp is owing to have long, energy-conservation, brightness advantages of higher of life-span, used as car light by increasing car production manufacturer, its concrete structure is as follows: the LED lamp of lamp interior at first is divided into several groups, every group LED forms LED lamp string through the series connection back, many group LED lamp strings link to each other with car body controller through back in parallel again, control the work of all car lights by car body controller, simultaneously also by car body controller by detecting the variation of car light total current, judge whether et out of order of car light.But because the connection mode of above-mentioned LED lamp is different with traditional car light, even there is certain even certain group LED bulb to open circuit or short circuit, its influence to the car light total current is all very little, therefore car body controller can't detect the slight change of electric current, also just can not be in time to the chaufeur alarm, after the fault brightness reduction of car light, traffic safety is had very big risk because of the LED lamp.In addition, there is bigger difference between the car light of each position of automobile, for example the difference of the LED working current of forward and backward light fixture is bigger, / 3rd or 1/4th of the LED working current of back light fixture or even the LED of a preceding light fixture group working current, after damaging several in the LED lamp group of current like this light fixture, though can also normally use, but because BCM can't accurately detect the position and the number of the LED lamp that is damaged, therefore can cause the BCM misjudgment, begin to report to the police, increase use cost to client.
Summary of the invention
First purpose of the present invention is to propose a kind of LED light fault detection system that can accurately detect each car light failure condition.
The alarm device that LED light fault detection system of the present invention comprises car body controller, links to each other with car body controller, key are that described car body controller also connects the Lighting Controller of a plurality of LED of being integrated with driver modules and current detection module.
The present invention connects a last Lighting Controller that independently is integrated with LED driver module and current detection module with each car light, this Lighting Controller not only can drive car light work, can also monitor the electric current of car light in real time, because each Lighting Controller is only at a car light, control, the LED lamp negligible amounts that detects, therefore accuracy in detection promotes greatly, can accurately measure the electric current situation of change of car light, and judge this car light according to the electric current situation of change and whether can also normally use, promptly whether influence traffic safety, if the fault of this car light has had influence on traffic safety, then this Lighting Controller sends alarm message to car body controller, remind the driver to note the car light fault, if the fault of this car light does not have influence on traffic safety as yet, then this Lighting Controller can not send alarm message to car body controller, avoids frequent maintenance to increase use cost to the car owner.
Above-mentioned Lighting Controller preferably is integrated with the LIN communication module, and described car body controller links to each other with each Lighting Controller by the LIN bus.The LIN bus has advantages such as cost is low, and circuit is simple, transfer rate is high, the signal transmission delay time is short, is fit to the communication between Lighting Controller and the car body controller.
Described alarm device is instrument or loudspeaker, and type of alarm is direct, eye-catching.
Second purpose of the present invention is the method for inspection that proposes the LED light fault detection system of the above-mentioned LIN of having bus.
Method of inspection of the present invention comprises following steps: the electric current of the car light that the monitoring in real time of each Lighting Controller is coupled, when the electric current of certain car light changes above preset range, coupled Lighting Controller sends alarm message to car body controller, car body controller is controlled the concrete work of this Lighting Controller according to the car light failure condition, and carries out alarm by the alarm device.
Above-mentioned Lighting Controller comprises current value information at least in the alarm message that car body controller sent, judge and maintainer's reference when keeping in repair car light for car body controller.
Above-mentioned Lighting Controller preferably also comprises the car light condition information in the alarm message that car body controller sent, when the car light electric current surpasses the setting threshold values of Lighting Controller driver module or be lower than the open circuit limit value, just represent that this car light can't work, must keep in repair at once, after the information of Lighting Controller comprises the car light condition information of above-mentioned two kinds of situations, can remind car body controller to send prompt messages to chaufeur at once, avoid influencing traffic safety.
Find the fault car light rapidly for making things convenient for chaufeur, reduce maintenance time, after car body controller receives the information that Lighting Controller sends, at first judge according to the car light condition information whether car light can also work on, when car light can't work on, car body controller carried out alarm by the alarm device; When car light can also be worked, car body controller sent and controls signal to this Lighting Controller when carrying out alarm by the alarm device, controlled coupled car light by the preset frequency flicker.Chaufeur can come the position of trouble locating car light according to car light flicker situation like this, has only when the fault car light can't be worked, and chaufeur just need be opened the position of car light with the trouble locating car light one by one.
LED light fault detection system of the present invention is simple in structure, its method of inspection practicality, can accurately detect the electric current situation of change of each car light, thereby in time find the car light fault and carry out the fault alarm prompting, avoid the detection of traditional light fault detection system inaccurate, problem such as easy flase alarm, strengthened travel safety and reduced use cost.
