Problems solved by technology

At present, the detection of the friction coefficient of the wet road surface is usually obtained by detecting various physical quantities such as resistance, temperature, humidity, etc., and then through the relationship curve and theoretical calculation to obtain the theoretical calculation value of the road surface friction coefficient. However, the relationship curve between the road surface friction coefficient and various physical quantities It is often very complicated and is mostly a theoretical relationship after ignoring other variables. Its correctness and accuracy are both worthy of consideration. Moreover, the friction coefficient of the road surface is often affected by various road surface conditions and environments. The theoretical calculation results are very likely to be very different from the actual situation; in addition, most of the current sampling tests are not comprehensive

Abstract

The invention relates to the field of road detection, and particularly relates to a pavement slippery state detection system and method. The method comprises the steps: 1, starting a control motor, enabling a sweeping roller to rotate to ground at a front end of a device, starting a sweeping motor, and transmitting the sweeping roller to sweep an advancing road of the device; 2, making a locking pin slide into a locking hole in a lower end of a fixing seat through an elastic force of a locking spring, locking a position of a measuring mechanism, and making a friction block make contact with the ground; 3, rotating a threaded adjusting sleeve to enable a threaded rod to drive a connecting base to move downwards, and extruding a friction block through a pressure spring to form certain pressure on the ground; and 4, starting a mobile motor, making the device move forwards at a constant speed, transmitting a friction force existing between the friction block and the ground to a measuring sliding seat so that the measuring sliding seat slides backwards on a measuring sliding column, and after the position of the measuring sliding seat is relatively stable, combining a reading pointer indicating value with a downward moving value displayed on a limiting sliding column so that a slippery state degree of a road surface is detected.

Description

technical field [0001] The invention relates to the field of road detection, in particular to a detection system and method for wet and slippery road conditions. Background technique [0002] Highway pavement should have sufficient anti-skid ability to ensure driving safety. If the anti-skid ability of the road surface is insufficient, it will have a significant impact on driving safety. Studies at home and abroad have shown that the traffic accident rate on wet and slippery roads is 3-7 times higher than that on dry roads. A key factor affecting the anti-skid ability of the road surface is the friction coefficient of the road surface. If the friction coefficient of the road surface is too small, the vehicle will not have enough adhesion and driving force when driving on the road surface, and the vehicle will easily slip or the braking distance will increase. Dangerous, especially when the road surface is wet and slippery after rain, the friction coefficient of the road sur...
