In this embodiment, the drying wheel 4 can be pushed by the running gear to move, and can also be driven by the driving motor to move.
When the drying wheel 4 is pushed to move by the walking device, the rotating speed of the drying wheel 4 is the same as that of the wheel 9.
When the drying wheel 4 is driven by the driving motor to move, in one mode, the walking device loses the power of the walking device and is completely driven by the driving motor of the drying wheel 4 to walk; in another way, the running gear is still driven by the driving unit of the running gear, at this time, the active motion of the drying wheel 4 can enable the drying wheel 4 to slip and slow down, the drying time is increased, and the drying effect is ensured.

For example, when it is determined that the thickness and the shape of the marked line exceed the first threshold, the driving motor is started to drive the drying wheel 4 to rotate, and the rotation speed is smaller than the running speed of the wheel 9, which indicates that the thickness and the solidification state of the marked line do not meet the first given requirement (i.e., the first threshold, and thus the thickness and the solidification state do not meet the basic requirement), and the drying wheel needs to be slightly used for braking to increase the spraying and drying time; when judging that the thickness and the shape of the marked marking exceed the second threshold, the driving motor starts and drives the drying wheel 4 to reversely rotate relative to the wheel 9, at the moment, the marked marking thickness and the solidification state are shown to be not met with the second given requirement (namely, the second threshold, the thickness and the solidification state are seriously not met with the requirements), the drying wheel is required to be adopted for reversely braking, and when the spraying and drying time is prolonged, early warning is carried out to prompt operators to carry out equipment inspection so as to ensure the normal follow-up work. By the arrangement mode, the sprayed marked lines are monitored in real time, and the braking action of the drying wheel is creatively utilized for carrying out linkage control, so that a new thought is provided for real-time control.

The embodiment also provides a road marking quality monitoring method for monitoring the marking quality of the road marking device, which comprises the following steps:
and a correlation is arranged between the coating flow rate of the coating outlet and the walking speed of the water bath tank, and the influencing factors of the correlation comprise the ambient humidity and the discharging temperature. The relative relation between the coating flow rate of the coating outlet and the walking speed of the water bath tank can be a proportional relation, and the proportional coefficient is adjusted according to factors such as natural environment, use scene and the like. When the humidity in the natural environment is high, the proportion coefficient of the coating flow rate of the coating outlet and the travelling speed of the water bath tank is small; and when the humidity in the natural environment is small, the proportion coefficient of the coating flow rate of the coating outlet and the walking speed of the water bath tank is large. When the window time of construction is short, the proportion coefficient of the coating flow rate of the coating outlet and the travelling speed of the water bath tank is large; when the window time of construction is long, the proportion coefficient of the coating flow rate of the coating outlet and the walking speed of the water bath tank is small.
A driving motor is arranged to drive the drying wheel 4 to move. In this embodiment, the road marking quality monitoring method further comprises that the drying wheel 4 is driven by the running gear or by the driving motor.
When the drying wheel 4 is pushed to move by the walking device, the rotating speed of the drying wheel 4 is the same as that of the wheel 9.
When the drying wheel 4 is driven by the driving motor to move, in one mode, the walking device loses the power of the walking device and is completely driven by the driving motor of the drying wheel 4 to walk; in another way, the running gear is still driven by the driving unit of the running gear, at this time, the active motion of the drying wheel 4 can enable the drying wheel 4 to slip and slow down, the drying time is increased, and the drying effect is ensured.
The source of the control signal of the start-stop and motion parameters of the driving motor of the drying wheel may be a marking detection device 11 arranged below the travelling device in one embodiment, and the marking detection device 11 detects the thickness and the shape of the marked marking; the marking detection device 11 is in communication connection with a driving motor of the drying wheel 4, and the steering and the rotating speed of the driving motor are controlled according to signals of the marking detection device 11. For example, when the thickness and the shape of the marked mark exceed the first threshold, the driving motor is started to drive the drying wheel 4 to rotate, and the rotating speed is smaller than the wheel 9; when the thickness and the shape of the marked mark exceed the second threshold, the driving motor is started to drive the drying wheel 4 to reversely rotate relative to the wheel 9.
In other embodiments, the control signal sources of the start-stop and motion parameters of the driving motor of the drying wheel further comprise the temperature measuring module and the humidity measuring module.
Further, in another embodiment, the control effect of the liquid flow channel 402 on the outlet 403 of the liquid flow channel is described by the following formula:
M(t)＝Le -At/M
wherein L is the static coefficient of the water bath pipeline;
a is the water containing amount in the drying wheel;
m is the flow of the water bath medium, i.e., water;
a/M is the residence time of the water in the water bath in the drying wheel;
t represents the control estimation and influence of the formula on temperature;
it should be noted that the above formula is an empirical fitting formula performed by those skilled in the art during actual spraying, and is basically self-heat transfer, and will not be described herein.

first, the spray nozzle identifies the type of paint (e.g., different types of paint are used for different use environments and requirements);
judging whether the type of the spray nozzle (such as parameters of the aperture size of the spray nozzle and the like) accords with the type of the paint, if so, carrying out subsequent spraying, and if not, prompting to replace the spray nozzle which accords with the requirement;
detecting the temperature and the humidity of the surrounding environment of the spray nozzle;
the monitoring equipment calls a database, and the database stores optimal values corresponding to the spray nozzle type, the spray material type, the corresponding temperature and the humidity;
under the condition that the optimal numerical values corresponding to the type, the type and the corresponding temperature and humidity of the spraying nozzle are stored in the database, the monitoring equipment controls the spraying speed of the spraying nozzle by adopting the optimal numerical values recorded on the basis of the temperature and the humidity of the surrounding environment of the spraying nozzle;
the database also stores corresponding paint solidification parameters, and the monitoring equipment calls the parameters according to requirements and controls the running speed of the equipment;
