The first step, the second step and the related contents are taken as an invention point of the embodiment of the disclosure, and the technical problem mentioned in the background art is solved, namely, whether cracks exist on the road surface is only identified, and the severity of the cracks is not quantified, so that maintenance personnel cannot intuitively know the severity of the cracks. ". Factors that cause maintenance personnel to not be able to intuitively know the severity of the crack are often as follows: only whether cracks exist on the road surface is identified, and the severity of the cracks is not quantified. Therefore, the crack severity is quantified by the road crack grade, screening is carried out, and road crack address information is generated according to the position information of the road crack grade meeting the preset early warning grade condition, so that the road crack address early warning information is generated. And generating highway crack grade early warning information according to the highway crack grade meeting the preset early warning grade condition.

The terminal device may be a device that receives highway crack warning information. Each terminal device is logged with a user account of the user. And the user account corresponding to each terminal device is responsible for receiving the highway crack early warning information in a fixed area. In practice, the execution subject may determine the identities of all terminal devices as a terminal device identity set.
And secondly, selecting a terminal equipment identifier with corresponding area information matched with the position information from the terminal equipment identifier set as an alternative terminal equipment identifier to obtain an alternative terminal equipment identifier set. The area information may be, for example, information (for example, area name) related to an area including each road segment. For example, the above area information may be "XX district of XX city XX province". Here, the matching of the area information and the position information may be: the position represented by the position information is within the area represented by the area information.
And thirdly, acquiring the terminal equipment position information corresponding to each candidate terminal equipment identifier in the candidate terminal equipment identifier set to obtain a terminal equipment position information set. The terminal device location information may be a specific location where the terminal device corresponding to the corresponding candidate terminal device identifier is located. The specific location may be obtained using GPS positioning. In practice, the execution main body may select, from the previously received location information of each terminal device, location information corresponding to each candidate terminal device identifier in the candidate terminal device identifier set as the terminal device location information.
And fourthly, selecting the terminal equipment position information meeting the preset distance condition from the terminal equipment position information set as the target terminal equipment position information according to the position information. The preset distance condition may be that a distance between a position corresponding to the position information of the terminal device and a position corresponding to the position information is the closest.
And fifthly, determining the candidate terminal equipment identifier corresponding to the position information of the target terminal equipment as the target terminal equipment identifier.

". Factors that cause maintenance personnel to fail to perform maintenance in a timely manner are often as follows: the maintenance personnel are far away from the cracks on the road surface. Therefore, the method and the device have the advantages that the user account corresponding to the terminal device is used for receiving the highway crack early warning information in the fixed area, so that when the highway pavement crack meeting the preset early warning level condition is detected, the highway crack early warning information can be timely sent to the terminal device closest to the terminal device, and reasonable personnel distribution is achieved. Furthermore, maintenance personnel can take corresponding maintenance measures to the cracks of the road surface in time, and the cracks of the road surface can be guaranteed to be repaired in time.
