用英文描述一下电子警察的工作原理和好处How speed camera run and the advantages of speed camera
First of all,I want to say about the classification of electronic police,
One,according to the function:the red light electronic police,the police for speeding electronic,bayonet type electronic police (i.e.for every pass through the road vehicle records,
Mainly for the security check vehicles used for transportation,not punishment,of course,can also add function,can be used as a vehicle speeding penalties).In addition we
The derived from many other electronic police:
No left electronic police
(road can not be left)
,
Retrograde electronic police
(retrograde or one-way street snap)
,
Illegal lane change electronic police (the intersection line of variable capture,the technical content is very high,the plate than many technology) etc..
Two,according to standard:camera type electronic police,digital camera,electronic police,as well as the new high-definition video electronic police.This refers to the electrical
The police before shooting equipment.
Three,according to capture method:induction coil capture,video capture,radar,infrared shooting,piezoelectric sensing etc..Of course the first
The most cheap,only life generally
2
Years,
2
Years after the re cutting coil.
The above is the general classification of electronic police,specific and many in this no longer endure the.
The following are some of the key problems:
One,on the body but stop line problem:
Saying:"three is valid
,
Photographic evidence rules is this.The general picture is that the evidence:
The first is the front line
Second is the rear a cordon
The third picture you across the intersection line
"
Red light camera type electronic police general evidence photos should be four piece,three Zhang body panorama,a rear license plate features photos,to see the car
Card number.The shooting method for digital camera type is captured three Zhang Quanjing,because of high pixel rear plate can zoom in to see.Three Zhang Quanjing photographs should be
This is respectively,the car did not press the stop line,the body half pressed the stop line,all the body of a parking type.Not mentioned in the article "the third is
You across the intersection line ",you have to know how to alert across the intersection line?Opposite the white lines in the same direction lane entrance?
So your strategy:"you front had not tight,as the first,never mind,you still will not illuminate second pieces,if you move,trigger
Second your rear wheel too,so don't matter,you just crossing,or you stop outside across the intersection line can be!Again
That said,you just the first piece of the front wheels are taken,some people may think back about can always do,wrong,a retreat,and trigger a!Oh
Oh!
"
This doesn't work,you know the traffic regulations is your body over the stop line belongs to the red light.
Also our embedding method coil is the stop line in front of a meter
2
A coil,or stop line before and after a.And not trigger only
Pat,is the original camera has been shot,but if you pressed the induction coil,then put the image because of pressing coil under the reservation
To (the camera mode).
Two,license plate on the dot
Saying:"you see your car licence first letter behind the small dot not!
This is a small bit of rare earth metal to set up,its function is used to focus the electronic eye!
The world production of standard ha licence!To insert what
Is a Japanese
Sony
Carry out company!
So,don't look down on Chinese cars,Japanese cars,at least I car thing belongs to the Japanese technology!
Insiders said,this small piece of the original is a rare earth metal,in the light of the induction can produce for microwave signal electronic eyes capture faint
.
What shall I do?It's simple.
Subtract after properly preserved,when inspection with double-sided adhesive,check up and.Hey.Electronic eyes do not know you
License plate number.Is
" 0"
Or
" 8"
Ha-ha.
These things are a lot of police's uncle did not know!
The police explained a lot of only half,forgery,also has this function."
This is totally wrong,the dots have the anti-counterfeiting function,not to focus,but also Japan
SONY
Technology.
Why?Because the electronic police we are pre commissioning fixed focal length,but not before each snap zoom,so there are no
In focus.
Whether the camera type electronic police and digital cameras,electronic police is so,because as long as you can make it clear before the stop line
3-5
Metres area panorama
And before the stop line
3
License plate area meters can be.
Three,about the time to capture:
Saying:"yellow light,camera system delay
2s
After the start; when the red light,green light system has been launched; will be bright,advance
2s
Closed system
System,mainly in order to prevent the misuse of film.So many taxi drivers all know,can be almost gone,like nothing on this.But
Suggest that you do not,because the time is more difficult to understand."
Explanation:trigger electronic police is to supply signal lamp lights as the prerequisite,that is only the red light to electricity work,does not exist
