Abstract
A kind of Automobile light fault-tolerance method, comprising: (1) stoplight stop lamp, fog lamp lost efficacy, fault-tolerant networks: substitute with Warning light; (2) country beam lost efficacy, fault-tolerant networks: passing light+Warning light; (3) passing light lost efficacy, fault-tolerant networks: Warning light; (4) Warning light lost efficacy, fault-tolerant networks: position lamp.Advantage is: when some light lost efficacy, adopt above-mentioned fault-tolerant networks, effectively can reduce safety hazard, ensure that the driving safety of automobile, avoids life injury and property damage.
Description
Technical field
The present invention relates to car bulb technical field, specifically a kind of Automobile light fault-tolerance method.
Background technology
Car bulb is divided into signal lamp and illuminating lamp, and intact car bulb is the basic guarantee of safe driving.
Current car bulb does not possess fault freedom.After such as fog lamp lost efficacy, fog lamp cannot be lighted, and travelling in fog day just exists safety hazard; Such as stoplight stop lamp lost efficacy again, easily caused car rear-end.
When fog lamp, taillight lost efficacy, if can replace with Warning light, just greatly safety hazard can be reduced.
Summary of the invention
The object of the invention is development Real-Time Monitoring lighting loads electric current, once find bonding (open circuit) or open circuit, then adopt light fault-tolerant, the Automobile light fault-tolerance method substituted with predetermined light.
Automobile light fault-tolerance method of the present invention, comprising:
Country beam lost efficacy, fault-tolerant networks: substitute with passing light+Warning light;
The principle that realizes of the present invention is that (Fig. 1 and Fig. 2) adopts MCU (MicroControlUnit) Chinese microcontroller or controller, is commonly called as: micro controller system; Be generally called controller herein, car light service conditions all on monitoring car in real time, initial condition controller controls the port output low level of optocoupler, and optocoupler is ended, and the switch of car light is only by the control of former master cock on car.Controller carries out circulation real time scan to the switch of car light on car, the on-off signal of real-time monitor and detection car light, when detecting that a certain lighting switch is opened, namely require that car light is bright, whether the car light detecting this correspondence again works, controller will detect its working current in real time, if paranormal scope or the strange phenomena such as not, just thinks that this lamp breaks down.Controller will with presetting fault-tolerant networks, and controller will be operatively connected to the port of corresponding car light optocoupler, controls to export high level, and make optocoupler conducting, corresponding car light will be bright, and Here it is replaces with other predetermined car light is bright.
As country beam lost efficacy, fault-tolerant networks: passing light+Warning light; (with reference to figure 2), when driver's night travel, needs to open country beam illumination.Driver can push country beam mark place (connecting main furnace building light switch S2), and (controller, at initial condition, controls optocoupler port output low level, does not control the connection of any car light and lights, and the switch of car light is only by the control of former master cock on car.) connect main furnace building light switch S2, it is dark that on-off signal controls high-beam light shining, connects just bright, disconnects just dark.Detect that driver connects main furnace building light switch S2 during controller ADC3 cause for gossip.After main furnace building light switch signal being detected, sampling resistor RS2 just detected, controller ADC3 mouth gathers the voltage signal on RS2, is converted into current value, has judged whether that electric current flows through by ohm law.When having detected that corresponding electric current flows through, just judge that country beam is normal work; Otherwise, just judge country beam non-normal working, or damage.(with reference to figure 3 and Fig. 4) this Time Controller will connect the control mouth of passing light and Warning light, controller control port PORTA.0 and PORTA.4 exports high level, optocoupler conducting, K switch 1 and K switch 4 adhesive, passing light and Warning light bright, be exactly that country beam lost efficacy like this, fault-tolerant networks method: substitute with passing light+Warning light is bright, play suggesting effect.
The advantage of Automobile light fault-tolerance method of the present invention is: when some light lost efficacy, adopt above-mentioned fault-tolerant networks, effectively can reduce safety hazard, ensure that the driving safety of automobile, avoids life injury and property damage.

Detailed description of the invention
Automobile light fault-tolerance method, comprising:
Country beam lost efficacy, fault-tolerant networks: passing light+Warning light;
Country beam lost efficacy, fault-tolerant networks: substitute with passing light+Warning light; (with reference to figure 1 and Fig. 2), when driver's night travel, needs to open country beam illumination.Driver can push country beam mark place (namely connecting main furnace building light switch S2), and (controller, at initial condition, controls optocoupler port output low level, does not control the connection of any car light and lights, and the switch of car light is only by the control of former master cock on car.) connect main furnace building light switch S2, it is dark that on-off signal controls high-beam light shining, connects just bright, disconnects just dark.Detect that driver connects main furnace building light switch S2 during controller ADC3 cause for gossip.After main furnace building light switch signal being detected, sampling resistor RS2 just detected, controller ADC3 mouth gathers the voltage signal on RS2, is converted into current value, has judged whether that electric current flows through by ohm law.When having detected that corresponding electric current flows through, just judge that country beam is normal work; Otherwise, just judge country beam non-normal working, or damage.(with reference to figure 3 and Fig. 4) this Time Controller will connect the control mouth of passing light and Warning light, controller control port PORTA.0 and PORTA.4 exports high level, optocoupler conducting, K switch 1 and K switch 4 adhesive, passing light and Warning light bright, be exactly that country beam lost efficacy like this, fault-tolerant networks method: substitute with passing light+Warning light is bright, play suggesting effect.
Claims (1)
1. an Automobile light fault-tolerance method, is characterized in that: comprising:
Country beam lost efficacy, fault-tolerant networks: substitute with passing light+Warning light;
Country beam lost efficacy, fault-tolerant networks: substitute with passing light+Warning light and comprise: when driver's night travel, needed to open country beam illumination; Driver can connect main furnace building light switch S2, and controller, at initial condition, controls optocoupler port output low level, does not control the connection of any car light and lights, and the switch of car light is only by the control of former master cock on car; Connect main furnace building light switch S2, it is dark that on-off signal controls high-beam light shining, connect just bright, disconnect just dark, detect that driver connects main furnace building light switch S2 during controller ADC3 cause for gossip, after main furnace building light switch signal being detected, sampling resistor RS2 just detected, controller ADC3 mouth gathers the voltage signal on RS2, is converted into current value, has judged whether that electric current flows through by ohm law; When having detected that corresponding electric current flows through, just judge that country beam is normal work; Otherwise, just judge country beam non-normal working, or damage; This Time Controller will connect the control mouth of passing light and Warning light, controller control port PORTA.0 and PORTA.4 exports high level, optocoupler conducting, K switch 1 and K switch 4 adhesive, passing light and Warning light bright, be exactly that country beam lost efficacy like this, fault-tolerant networks method: substitute with passing light+Warning light is bright, play suggesting effect.
