Description
Technical field
A kind of mobile laboratory's formula road planar condition test device and method belong to multi-functional Quick Test Vehicle field.
Background technique
Have become the master of highway engineering correlate values using multi-functional Quick Test Vehicle as the detection mobile laboratory of representative
Want detection instrument.With the development of highway measurement technology, highway, which measures mobile laboratory, will also become the new bright of industry development
Point.
Road planar condition: road planar condition described in this patent refers to the reflex reflection optical property situation of roadmarking.Reflex reflection: road
The reflex reflection of graticule is different from mirror-reflection and diffusing reflection, it refers to that light is incident on roadmarking with 88.76 ° of incidence angle, then
With the special optical phenomenon for the angle reflection for being 1.05 ° with incident light angle.
With greatly developing for Construction of Highway Traffic, the market share of road traffic marking reflex reflection measuring device is increasingly
Greatly, the demand of unit in charge of construction, supervisor, detection unit and production unit to road traffic marking reflex reflection measures constantly increases
Add.Industry key lab possesses the instrument of test road traffic marking photometric characteristic at present, but existing instrument was using
Many of journey limitation.For example, existing portable graticule reflex reflection tester is only used for the experiment of road traffic marking
Room test and the contact test for graticule of having constructed, test condition require strictly, not being suitable for large area rapid survey.Road at present
When the traffic marking on-site test of road, artificial means are all made of, i.e. testing staff is carried out using portable graticule reflex reflection tester
Live manual measurement, not only large labor intensity, working efficiency are low, testing cost is high, but also data collection capacity is limited, and representativeness is not
By force, detection data repdocutbility is restricted.Meanwhile at the road of open to traffic scene, such operation risk is extremely strong, safety
Hidden danger is at all times.Project team finds in investigation, since there are the above problem, part testing agency uses the side of test sample
Formula evaluation Practical Project, which is applied, draws graticule, causes testing result that can not react real road traffic marking quality, road safety basis
Facility quality, which is unable to get, to be effectively ensured.
315 parties in 2018 reflect individual roadmarking productions enterprise to speculate, and use inferior materials and turn out substandard goods, and use
The mode of submitted sample escapes supervision, causes testing result that can not react real road graticule quality, road safety infrastructure
Quality, which is unable to get, to be effectively ensured, and situ metrology support rapidly and efficiently is badly in need of in the supervision and management of highway engineering quality.Therefore, originally
Patent proposes a kind of mobile laboratory's formula road planar condition test device and method.
Scene sampling and the situ metrology of quality surveillance and testing agency's management may be implemented in highway metering mobile laboratory,
Fast and accurately foundation is provided for quality management.Establishing highway metering mobile laboratory is augmented measurement supervision and management, service warp
One effective measures of Ji social development.Mobile laboratory is measured by highway, so that highway metering service is come into market, comes into enterprise
Industry realizes advance-service, follow-up service, Site Service, more effectively more timely provides safeguard, make for Highway Engineering Quality Supervision
Highway, which measures mobile laboratory, becomes the another powerful measure of service society.
At present for measuring channels planar condition traditional technology and equipment be based on closed optical path based on standard A light source
Portable reflex reflection graticule measuring instrument.
Reflex reflection graticule measuring instrument is generally made of standard A light source and recipient, and Plays A light source color temperature is 2856K
±50K.Reflex reflection graticule measuring instrument carries out using artificial means when the measurement of road planar condition, i.e. testing staff uses portable graticule
Reflex reflection tester carries out live manual measurement, measures the opposite error of indication and is generally ± 5%.
Present technology has the disadvantage in that
1) measuring speed is slow.It is single to mark since the equipment of prior art manufacture needs to carry out self calibration manually before measuring
Line measurement is about 5 minutes time-consuming.
2) heavy dependence environmental condition.Measurement result is easy to be influenced by ambient irradiation, therefore the prior art needs
Want equipment and measurand to be in an enclosed environment, if there are other light sources between equipment and measurand, equipment without
Method measurement obtains accurately as a result, the error of indication can be greater than 100%.
3) blocked road traffic is needed.Due to being handheld device, and measuring speed is slower, therefore in road survey process
In need close traffic, to guarantee the safety of survey crew.
4) the measurement error of indication is larger.The opposite error of indication of the prior art is ± 5%, and being unable to satisfy Practical Project needs
It asks.

45 ° of reflective mirror d, semi-transparent semi-reflecting lens and the spiral regulation mouth of light out pass through the time of central point consuming about by same straight horizontal
For 0.008s, in the case where terminating self calibration or non-self-calibration mode, control self calibration motion module moves 45 ° of reflective mirrors of self calibration
The time for moving initial position consuming is about 0.008s, and the time that light is propagated can be ignored, the response time of receiver
No more than 0.005s, it is contemplated that the time of measuring of the other factors interference in device, single graticule can be not more than 0.03s, so that
Device can be loaded to be measured under the speed of speed per hour 100km/h on automobile or unmanned plane.
In conjunction with the optical path that this patent designs so that laser beam from laser launch after to the light path etc. testee
The light path that receiver is reached after laser beam is by testee reflex reflection, reduces asymmetric damage of the light beam in communication process
Consumption provides the foundation to improve measurement accuracy.Also, since this patent can be completed once within the about time of 0.021s
Self calibration, therefore can be ensured of use before measurement every time and be measured just through self-alignment device, reduce system mistake
Difference.Experiment shows (some experimental data see the table below) that the measurement error of indication is not more than ± 2%.
Self calibration standard sample built in this patent, and it is filled with inert gas, external environment is avoided to self calibration standard
The damage of sample enables the reflectivity of self calibration standard sample to remain unchanged for a long time, ensure that the mark that device is calibrated every time
Quasi- value is all that accurately and reliably, will not therefore improve the error of indication of device.
