Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment one
The present embodiment is related to a kind of license plate automatic flushing device, as shown in Figure 1 comprising controller 1 is believed with controller 1
The connected engine start detection unit 2 of number input terminal, smokescope detection unit 3, Bus- Speed Monitoring unit 4, smokescope threshold
It is worth memory 5, and license plate washer 7 being connected with 1 signal output end of controller, being cleaned to license plate 6.
Wherein, vehicle ECU can be used in controller 1, constitutes the control to entire cleaning device；Engine start detection is single
Member 2 can use engine start sensor, and the Engine Start Signal to obtain Engine Start Signal and will acquire passes
Pass controller 1；Smokescope detection unit 3 is arranged where license plate 6, uses smokescope sensor, for vehicle
Smokescope where board 6 is detected, and the smokescope that will test passes to controller 1；Smoke density threshold value storage
Device 5 is used as information memory cell, is stored with the first smoke density threshold value；Bus- Speed Monitoring unit 4 is used for vehicle driving speed
It spends the vehicle speed information for being detected, and being will test and passes to controller 1；License plate washer 7 is used as executive component, is arranged in license plate
6 positions, it can be achieved that cleaning to license plate 6 under the control of controller 1, in the present embodiment, license plate washer 7 is adopted
It is grey when can prevent license plate from cleaning by the use of supersonic generator such as mechanical ultrasonic wave producer with supersonic generator
Muddy state occurs for dirt, effectively improves using effect.
License plate automatic flushing device as above, control method include the following steps:
Step a, engine start detection unit 2 detect Engine Start Signal, and Bus- Speed Monitoring unit 4 is to vehicle
Travel speed is detected, and the engine start information and vehicle speed information real-time delivery that will test are to controller 1；
Step b, smokescope detection unit 3 detect the smokescope at license plate 6；
Step c, when Vehicle Speed be greater than zero, and smokescope detection unit 3 detect smokescope value be greater than cigarette
When the first smoke density threshold value stored in mistiness degree threshold value memory 5, controller 1 controls license plate washer 7 and starts, and license plate is clear
It washes device 7 and ultrasonic activation occurs, so that the dust on license plate 6 is shaken and fallen, realize the cleaning to license plate 6.
When in order to be activated after being long placed in vehicle, license plate can be cleaned, in control method as above, step a with
Can also step a1 be equipped between step b: when engine start detection unit 2 detects engine start, and Bus- Speed Monitoring unit 4
When the car speed detected is zero, controller 1 controls license plate washer 7 and starts, to clean to license plate.
