Description

Scanning light source

Technical field

The utility model relates to a kind of lighting source, particularly relates to a kind of lighting source of narrow visual angle.

Background technology

In the existing management system in parking lot, many use IC-card management systems, carry by driver the information data transmission that IC-card completes vehicle circulation process.But there is following subject matter in this control system:

Car card divides defection to cause card to lose, and then card and vehicle are had a mind to or can form unintentionally the unexpected control procedure of blocking a car, and blocking many cars more, need manual intervention, cause administrative vulnerability.

Peak period, vehicle was come in and gone out frequent, swipes the card, paying dues needs driver repeatedly to carry out with fee-collector alternately, very easily causes vehicle congestion.Calculate through reality, a usual vehicle of normally coming in and going out needs parking card taking when entering parking lot, required time is generally 5-10 second, need card to pay fee-collector when leaving parking lot, fee-collector receives after card is swiped the card and quotes the amount of money, then through process of collecting fees, required time is probably more than 30 seconds, while delaying the personage down time of driving, parking stall turnover rate is low, also causes economic loss to parking lot.

How can ensure the fluency of data verification in control procedure, ensure the reliability of physical facility in proof procedure, physical facility, to the positive incentive of driving behavior pattern, all needs to do perfect further.Arrange at the physical hardware of pass gates at present and also there is following defect:

The shape of ground induction coil can not be very adaptive with track, make installation site limited, the laying of ground induction coil is simultaneously vulnerable to the impact of ground or sub-surface conductors, is interfered when perimeter conductors occurs that current field changes, and produces random triggering signal and causes controlled follow up device to start or close.

When adopting camera photograph to gather the number-plate number, limiting to by device parameters such as the camera lens depth of field, focal lengths, cannot reduce costs and collection apparatus is carried out to vehicle, and then the responsibility that cannot meet damaged vehicle setting loss is distinguished.

Be limited to the ambient influnence of banister installation site, hesitation when vehicle is come in and gone out and dodging, there is the easily damaged problem of collision rift of cranking arm with banister.

The accident collision of vehicle cannot be stoped in passage sluice gate, effectively cannot control the automatism of driver.

When driver is in start and stop state transformation, notice affects by environmental change, and vehicle often accurately can not be parked in mark position, causes down-stream to perform and occurs initial deviation.

In passage sluice gate installation process, comparatively large to ground failure and the amount of resuming work, the ground landscape restore cycle in later stage is longer.

Utility model content

The purpose of this utility model is to provide a kind of scanning light source, solves existing light source strong illumination too broad, the technical problem of meeting direct interference driver.

Scanning light source of the present utility model, comprises a rectangular column, offers a reflective groove in the upper surface of rectangular column, and the long sidewall that two of reflective groove are relative slopes inwardly, and long sidewall is coated with reflecting coating;

The LED of Same Wavelength is laid at the bottom even of reflective groove, parallel with the bottom of reflective groove, on the sidewall of reflective groove, fix softbox, the first prismatic lens, the second prismatic lens, prismatic glasses and convex lens plate successively from bottom to top.

Described first prismatic lens, the second prismatic lens with the prism axis on prismatic glasses to parallel.

The lower surface of described convex lens plate is plane, and upper surface is arc, and the arbitrary section of upper surface is the circular arc that radius is identical.

The light of described scanning light source to be left away direction towards vehicle, and the radiation direction of scanning light source and the view direction of narrow visual angle camera acutangulate.

The utility model effectively can form the illumination of narrow visual angle, form the pure monochromatic light belt of more stable vertical bar shape, cover in viewfinder range, meet narrow visual angle camera and accurately divide other local light illumination, the illuminance in not obvious other regions of lifting simultaneously, avoids causing other cameras dazzling light interference.

Upper system is by passing authorization data (comprising normal, Exception Type, confirmation, delayed acknowledgement etc.) under the first bi-directional data link, corresponding control data is sent to the first control extensions 110 by the electric FPDP 104 of corresponding connection by controller 100, control data is converted to corresponding control signal and is sent to pass gates 140 through corresponding digital-to-analogue converter 114 by the first control extensions 110, control banister to crank arm lifting, vehicle passes through.

When the continuous admission passage of vehicle, the second group solenoid of rear car in ground induction coil group, is converted to the rear car traveling-position sensed and rate signal after rear car traveling-position and speed data through respective mode number converter 115 and is sent to the first control extensions 110 (approach axis);

First control extensions 110 sendaisle inner brake 230 control signal, makes brake 230 be in the state of being free to slide;

Sight line shutter control signal in first control extensions 110 sendaisle, makes sight line shutter produce multi-colour luminous, improves driver attention;

After current vehicle is passed through, the first control extensions 110 sendaisle inner brake brake 230 control signal, make brake 230 be in stable state, rear car is passed through gradually;

When rear car arrives first group of solenoid, sight line shutter control signal in the first control extensions 110 sendaisle, make sight line shutter not luminous, rear car becomes front truck and continues to move ahead.

The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
