If P1 is not more than YHD and less than P2, generating a second maintenance early warning signal, namely prompting that light construction maintenance needs to be carried out on the road, and carrying out deceleration and slow running warning on vehicles going to the road according to the condition;
it should be noted that if the maintenance value P1 ≦ YHD < P2 calculated according to the correlation function indicates that light construction maintenance is required for the road, and the vehicle approaching the road is warned to slow down according to the situation, such as: if the water accumulation amount JS on the road is moderate, namely, under the rainy condition, partial water accumulation exists on the road, prompting workers to carry out light construction maintenance on the road, and carrying out deceleration and slow running warning on vehicles going to the road according to the condition; if the amount of the snow accumulated on the road surface JX is moderate, namely under the condition of snowing, the worker is prompted to carry out mild construction and maintenance on the road, and the vehicle approaching to the road is warned to slow down and crawl according to the condition; if the pavement sundry accumulation amount ZW is moderate, prompting workers to carry out light construction maintenance on the road, and carrying out deceleration and slow running warning on vehicles going to the road according to the condition; if the road surface damage area LP is moderate, the worker is prompted to carry out light construction maintenance on the road, and a vehicle which is about to go to the road is warned to slow down according to the condition; if the pavement marking defect area BQ is moderate, namely the pavement marking defect area influences the marking effect, prompting workers to carry out light construction maintenance on the road, and carrying out deceleration and slow running warning on vehicles going to the road according to the condition; if the roadside lawn growth CS is moderate, namely the road lawn growth influences the normal running of the vehicle, prompting workers to carry out light construction maintenance on the road, and carrying out deceleration and slow running warning on the vehicle which is about to go to the road according to the condition; if the yield MS of the seedlings at the roadside is moderate, namely the growth of the seedlings at the roadside influences the normal running of the vehicle, prompting workers to carry out light construction and maintenance on the road, and carrying out deceleration and slow running warning on the vehicle which is about to go to the road according to the condition; if some factors of the water accumulation amount JS, the snow accumulation amount JX, the sundry accumulation amount ZW, the road damage area LP, the road marking defect area BQ, the lawn growth amount CS and the seedling production MS occur at the same time, P1 is calculated to be not less than YHD and less than P2 according to the correlation function, the worker is prompted to carry out light construction maintenance on the road, and the vehicle which is about to go to the road is warned to slow down according to the condition.
If P2 is less than or equal to YHD, generating a third maintenance early warning signal, namely prompting that heavy construction maintenance is required to be carried out on the road, and carrying out a lane change warning on vehicles going to the road according to the situation;
it should be noted that if the maintenance value P2 is not greater than YHD calculated according to the correlation function, it indicates that heavy construction maintenance needs to be performed on the road, and a lane change warning is performed on the vehicle approaching to the road according to the situation, for example: if the water accumulation amount JS on the road is large, namely the water accumulation amount JS on the road is serious under the rainy condition, prompting workers to carry out heavy construction maintenance on the road, and carrying out lane change warning on vehicles which are going to go to the road according to the condition; if the amount JX of the snow accumulated on the road surface is large, namely under the condition of snow, partial snow is accumulated on the road surface, prompting that workers need to carry out heavy construction maintenance on the road, and giving a warning for changing the road to a vehicle which is about to go to the road according to the condition; if the pavement sundry accumulation amount ZW is large, prompting workers to need to carry out heavy construction maintenance on the road, and giving a warning for changing the road to a vehicle which is about to go to the road according to the situation; if the road surface damage area LP is large, prompting workers to need to carry out heavy construction maintenance on the road, and carrying out diversion warning on vehicles which are about to go to the road according to the situation; if the pavement marking defect area BQ is large, namely the pavement marking defect area seriously influences the marking effect, prompting workers to carry out heavy construction maintenance on the road, and carrying out lane change warning on vehicles going to the road according to the situation; if the roadside lawn growth CS is large, namely the road lawn growth seriously influences the normal running of the vehicle, prompting workers to carry out heavy construction maintenance on the road, and carrying out a diversion warning on the vehicle which is about to go to the road according to the situation; if the yield MS of the seedlings at the roadside is large, namely the growth of the seedlings at the roadside seriously influences the normal running of the vehicle, prompting workers to carry out heavy construction and maintenance on the road, and carrying out a diversion warning on the vehicle which is about to go to the road according to the condition; if some factors of the water accumulation amount JS, the snow accumulation amount JX, the sundry accumulation amount ZW, the road damage area LP, the road marking defect area BQ, the lawn growth amount CS and the seedling production amount MS occur at the same time, P2 is calculated to be less than or equal to YHD according to the correlation function, the method prompts a worker to carry out heavy construction and maintenance on the road, and warns the vehicle which is about to lead to the road to change the road according to the condition.
And the generated first maintenance early warning signal, the second maintenance early warning signal and the third maintenance early warning signal form a maintenance early warning set.
If P1 is not more than YHD and is less than P2, generating a second maintenance early warning signal, namely prompting that light construction maintenance needs to be carried out on the road, and carrying out deceleration and slow running warning on vehicles approaching to the road according to the condition, specifically:
acquiring position information of a road section needing to be maintained in a road, and acquiring position information of a plurality of workers who maintain the road;
it should be noted that, a road may be a certain road section or a plurality of road sections which need to be maintained, we can obtain position information of the road section in a positioning mode, and since we obtain the detected road surface water accumulation JS through the liquid level sensor, we can obtain the position information of the liquid level sensor when installing the liquid level sensor, we obtain the road surface snow accumulation JX, the road surface sundry accumulation ZW, the road surface damaged area LP, the road surface marked line defect area BQ, the road side lawn growth CS and the road side nursery stock production MS through the camera, and when installing the camera, we can obtain the position information of the camera; the worker carries the mobile terminal with him, and install GPS location on the mobile terminal, can learn worker's positional information.

If CT is less than T1+ T2; a vehicle approaching the road is warned of slowing down and crawling and the road section ahead of the vehicle is prompted to be maintained.
It should be noted that, when P1 is not less than YHD < P2, it indicates that the maintenance road section in the road does not affect the vehicle driving, and meanwhile, since CT < T1+ T2, it indicates that the road maintenance work is not completed when the vehicle drives to the maintenance road section, the vehicle needs to be reminded to perform deceleration operation.
Wherein, the vehicle is at the in-process that traveles, and navigation is all installed to the vehicle, and the road can in the in-process of carrying out the maintenance with maintenance relevant information send the navigation to the vehicle in real time, in time reminds the driver to drive at a slow speed.
When the CT is larger than or equal to T1 and T2, the worker finishes the maintenance work of the road section when the vehicle runs to the road maintenance road section, so that the normal running of the vehicle is not influenced, namely the vehicle about to go to the road is not required to be reminded to slow down.
If P2 is less than or equal to YHD, generating a third maintenance early warning signal, namely prompting that heavy construction maintenance is required to be carried out on the road, and carrying out a lane change warning on vehicles coming to the road according to the situation, specifically:
acquiring time XT required by a vehicle to travel from a road where a maintenance road section is located to a destination, and acquiring a time set Tn required by the vehicle to travel to the destination through other roads, wherein the value of n is 1,2,3 \8230;
it should be noted that, since the vehicle may have different road routes to the destination, the navigation system may know that the time required for the vehicle to travel to the destination on different road routes is different, so as to form a time set Tn required for the vehicle to travel to the destination on other roads.
Checking the severe maintenance-time table to obtain the time WT required by completing maintenance on the road section;
it should be noted that the severe maintenance-time table is obtained according to the statistics of the previous data, and the severe maintenance-time table records the values of the water amount JS, the snow amount JX, the accumulation amount ZW of the sundries on the road surface, the damaged area LP of the road surface, the defect area BQ of the road marking, the growth amount CS of the lawn on the roadside and the production amount MS of the nursery stock on the roadside, that is, the time required to complete the corresponding severe maintenance and the time required for the worker to travel to the severe maintenance road section.
Comparing Tn to XT + WT;
if XT + WT > Tn, a vehicle approaching to the road is warned to change the way.
It should be noted that P2 is less than or equal to YHD, that is, in the process of maintaining the road, the maintenance road needs to be closed to ensure driving safety, and when XT + WT > Tn, it means that the time required for the vehicle to travel to the destination through another road is short, so that the vehicle about to go to the road is warned to change the way.
And when XT + WT is less than or equal to Tn, it shows that the time required for the vehicle to travel to the destination through other roads is longer, and no warning is given for changing the road to the vehicle approaching to the road.
