Problems solved by technology
In reality, in order to obtain reliable experimental data, experimenters must make more asphalt (concrete) experimental panels, and simulate harsh environments such as low-temperature rainfall and snowfall in the climate simulation laboratory, observe the experimental phenomena for a long time and record the experimental data. Working in a low-temperature environment for a long time will not only easily cause physical discomfort, but also cause relatively low work efficiency. At the same time, the error of the experimental equipment will increase when the experimental equipment is in a low-temperature environment for a long time, which will affect the reliability of the experimental data.

The invention discloses a full-automatic road surface friction coefficient test system which comprises a solution preparing unit, a friction coefficient measuring unit, a video monitoring unit and a control unit, wherein the solution preparing unit, the friction coefficient measuring unit and the video monitoring unit are all connected with the control unit; the solution preparing unit comprises achemical agent storage device, a chemical agent automatic weighing device, a stirring device and a matching liquid transferring device; a box body and a temperature control element in the box body are arranged in the temperature control box; a spraying device comprises a matching liquid storage device and a plurality of spraying heads arranged on the upper side of the box body, and a pump body and a second electromagnetic valve are arranged between the matching liquid storage device and the spraying heads. According to the full-automatic road surface friction coefficient test system disclosedby the invention, all parts can be controlled by the control unit to automatically finish friction coefficient experiments; thus, the situation that body health of workers is affected due to performing manual experiments under low-temperature environment is avoided, and the workers can monitor experiment processes through the video monitoring unit.
Description
technical field [0001] The invention relates to a fully automatic road surface friction coefficient test system. Background technique [0002] In most areas of my country, deicing agents or deicing fluids will be sprayed on the roads before and after the snowfall in winter to avoid snow or ice accumulation on the roads. Although the roads will not freeze after the treatment, whether the friction coefficient of the road surface at this time is To control it within a reasonable range, this problem must be fully and correctly verified in the laboratory before it can be applied to actual engineering. In reality, in order to obtain reliable experimental data, experimenters must make more asphalt (concrete) experimental panels, and simulate harsh environments such as low-temperature rainfall and snowfall in the climate simulation laboratory, observe the experimental phenomena for a long time and record the experimental data. Working in a low temperature environment for a long time...
