s14, evaluating the environment information and the image information, judging the early warning value of the highway maintenance area where the current inspection vehicle is located, and sending first prompt information to the inspection vehicle when the early warning value is lower than a preset threshold value.
It should be noted that, the inspection vehicle shown in this embodiment may be obtained by modifying an existing highway inspection vehicle, and the rest structures of the inspection vehicle are the same as those of the existing highway inspection vehicle; the Beidou positioning module can adopt the existing chip or processor loaded with the Beidou positioning technology, and can acquire geographic position information corresponding to the current patrol vehicle in real time; the sensing module is configured according to different acquired information, for example, when the road surface humidity in the road inspection process is required to be acquired, the sensing module is preferably a humidity sensor, when the road surface temperature in the road inspection process is required to be acquired, the sensing module is preferably a temperature sensor, and when the road surface vibration amplitude in the road inspection process is required to be acquired, the sensing module is preferably an amplitude detector. Preferably, the sensor module includes a plurality of sensors, and each sensor has different functions, that is, the sensor module may include a temperature sensor, a humidity sensor and an amplitude detector, so as to collect environmental information of the road inspection section comprehensively.
The camera module can be a video camera, a camera and the like, is arranged on the inspection vehicle, can acquire image information on the running direction of the inspection vehicle, has a road surface image in the image information, and specifically comprises at least one of a road surface disease type, a road surface disease area and a road surface disease quantity. The data transmission module can adopt the existing wireless communication interface, establishes communication connection with the server through a wireless transmission mode, and transmits image information, environment information and geographic position information to the server, so that the server can conveniently maintain data related to a corresponding highway maintenance area in a highway maintenance database in time.
Preferably, the height information of the acquisition end of the sensing module and the camera module on the inspection vehicle and the angle information data of the acquisition end during acquisition are stored in the server together, so that the server can restore the specific road surface state according to the height information and the angle information, and the size of the road surface disease area is accurately calculated.
The method steps shown in this embodiment are the main steps executed by the server. Specifically, when the inspection vehicle starts to execute highway inspection operation, the server periodically acquires the geographic position information of the current inspection vehicle acquired by the Beidou positioning module, and determines a highway maintenance area where the current inspection vehicle is located according to the geographic position information.
And preferably, under the premise, when the highway maintenance area is too large, the server can also determine the inspection range of the current inspection vehicle according to the geographic position information of the inspection vehicle, so that the data storage is convenient for different inspection positions in a single highway maintenance area. Specifically, when the driving distance of the patrol vehicle approaches to the boundary of the patrol range, the server can acquire the geographical position information corresponding to the current patrol vehicle acquired by the Beidou positioning module again, so that the frequency of acquiring the geographical position information by the server can be reduced, and the calculation force is saved; meanwhile, the maintenance path of the inspection vehicle can be monitored in time in the same highway maintenance area.
The sensing module can collect environmental information in the current highway maintenance area, such as humidity information, temperature information, road vibration value and the like. The method and the system realize real-time recording of related data of the inspection road section by the inspection vehicle through collecting environment information and image information and mapping and storing the environment information and the image information and the corresponding geographic position information of the current highway inspection vehicle, and record the related data of past inspection related to the geographic position information in the same set.
In this embodiment, environmental information and image information collected by the current inspection vehicle are also evaluated, an early warning value of a highway maintenance area where the current inspection vehicle is located is judged, a preset threshold is a preset judgment standard, preferably, the preset threshold is 80, when the early warning value is lower than the preset threshold, the server sends first prompt information to the inspection vehicle to remind an inspection person of paying attention to possible road surface problems of the current road section, so that the inspection person can change the maintenance operation flow in time, and the maintenance difficulty of highway maintenance is reduced.
In some embodiments, the method further comprises:
and acquiring environment information corresponding to the road maintenance area in the current database and whether the updating frequency of the image information is in a preset frequency range, if not, judging whether the current inspection vehicle has a repeated inspection problem, and sending second prompt information to the inspection vehicle when the current inspection vehicle has the repeated inspection problem.
The preset frequency range shown in this embodiment refers to the update frequency of the preset highway maintenance area, and preferably, the preset frequency ranges of different highway maintenance areas are different, for example, when the road surface wear rate in the highway maintenance area is too fast, the preset frequency range may be 1 month/time, and when the road surface wear rate in the highway maintenance area is slow, the preset frequency range may be 3 months/time. When the update frequency of the environment information and the image information corresponding to the highway maintenance area in the current database is too fast, namely, is smaller than a preset frequency range, the current inspection vehicle possibly has the repeated inspection problem, and when the current inspection vehicle sends the repeated inspection problem, the second prompt information is sent to the inspection vehicle to timely inform inspection staff of the current repeated inspection problem, so that the inspection staff can conveniently correct the inspection path in time, and the accuracy of inspection data is improved.
In some embodiments, determining whether the current inspection vehicle is experiencing a repeat inspection problem includes:
the geographic position information corresponding to the current patrol vehicle is recorded as first geographic position information, and all geographic position information of the current patrol vehicle passing in a preset time period is recorded as second geographic position information; and matching the first geographic position information with each second geographic position information, judging whether the current first geographic position information and the second geographic position information are overlapped or placed in the same preset geographic position range, and if so, sending second prompt information to the patrol vehicle.
In this embodiment, whether the repeated inspection problem exists is determined by the identity of the geographic position information of the inspection vehicle. It should be noted that, all the geographical position information of the current inspection vehicle passing through in a preset time period is recorded as second geographical position information, and the preset time period refers to a time interval from the start time to the current time of the inspection process of the inspection vehicle in the batch, and the following expression about the preset time period is the same as the above; in this embodiment, all the geographic information in the preset time period is recorded as second geographic position information, that is, the number of the second geographic position information is multiple, the first geographic position information and the second geographic position information are matched one by one, whether the current first geographic position information and each second geographic position information overlap or are placed in the same preset geographic position range is judged, if yes, the current inspection vehicle has the repeated inspection problem. The first geographic position information is set in a circular area with a radius of 3 meters, and if the first geographic position information is set in the circular area, the first geographic position information and the second geographic position information are set in the same geographic area even if the first geographic position information is not the same as the second geographic position information, namely the first geographic position information and the second geographic position information are set in the same geographic area, namely the repeated inspection problem of the inspection vehicle exists.
Preferably, the time factor can be introduced as a repeated inspection judgment standard of the same location, that is, the server can perform repeated inspection judgment on the first geographic position information of the location only when the time length of the current inspection vehicle at the first geographic position information exceeds the residence time length of the inspection vehicle at the location in a normal running state.
Referring to fig. 2 and 3, in some embodiments, determining whether a repeated inspection problem occurs in the current inspection vehicle includes:
s21, acquiring image information corresponding to geographical position information of a current inspection vehicle, calling a pavement disease type in the current image information, and marking the pavement disease type as a first pavement disease type;
s22, calling the pavement disease type in all image information acquired by the current inspection vehicle in the current database in a preset time period, and marking the pavement disease type as a second pavement disease type;

s31, acquiring image information corresponding to geographical position information of the current inspection vehicle, calling the pavement disease area in the current image information, and marking the pavement disease area as a first pavement disease area;
s32, calling the pavement disease area in all image information acquired by the current inspection vehicle in the current database in a preset time period, and marking the pavement disease area as a second pavement disease area;
s33, judging whether the approximation degree of the first pavement disease area and the second pavement disease area is in a preset approximation range, and if so, sending a second prompt message to the inspection vehicle.
In this embodiment, whether the inspection vehicle has a repeated inspection problem is determined by determining whether the type of the road surface damage or the area of the road surface damage appearing in the inspection road section of the inspection vehicle is the same.
Specifically, the specific process of judging the pavement disease type can be shown in fig. 2: the method comprises the steps of calling image information corresponding to geographical position information of a current inspection vehicle, extracting road surface disease types in the image information and marking the road surface disease types as first road surface disease types, wherein the first road surface disease types refer to combination of road surface disease types in a current road section instead of one of the road surface disease types, and likewise, the second road surface disease types refer to combination of the road surface disease types in the road section, in particular, the number of the second road surface disease types is related to the inspection road section of the inspection vehicle, namely, the inspection road section is taken as a minimum unit, all the road surface disease types acquired in the inspection road section are single second road surface disease types, and the number of the road sections after the inspection vehicle starts the inspection operation until the inspection is finished corresponds to the number of the second road surface disease types one by one.
