The method for detecting the first road by the detection device to obtain the first abnormal information may refer to a general method, which is not described herein again.
Step S202, the detection device sends first abnormal information to the server.
And after the detection equipment obtains the first abnormal information, the first abnormal information is sent to the server.

When the position of the first road surface on the first road is a road surface on the first road between the second road and the third road, the first road side devices within the preset range of the first road surface may also be all road side devices arranged on the first road, all road side devices arranged on the second road, and all road side devices arranged on the third road. It is understood that the number of the first roadside apparatuses is one or more.
Step S204, the first road side equipment broadcasts first abnormal information to vehicles within the coverage range of the first road side equipment.
The first road side equipment receives the first abnormal information and broadcasts the first abnormal information to vehicles within the coverage range of the first road side equipment.
After the vehicle receives the first abnormal information, the abnormal condition of the first road surface can be pushed to the user according to the first abnormal information.
When the first abnormality information is the first implementable manner, and the position of the first road surface includes the identifier of the first road corresponding to the first road surface or includes the position of the first road surface on the first road, or the first abnormality information is the second implementable manner, the vehicle may push the abnormality of the first road surface to the user according to the first abnormality information, and the method may include: and the vehicle plays or displays the first abnormal information.
When the first abnormal information is the first implementable manner described above, and the location of the first road does not include the identifier of the first road corresponding to the first road surface nor the location of the first road surface on the first road, and includes the coordinate of the first road surface under the geographic coordinate system, the vehicle pushes the abnormal condition of the first road surface to the user according to the first abnormal information, which may include: the vehicle acquires the identifier of the first road corresponding to the first road surface or the position of the first road surface on the first road according to the coordinates of the first road surface under the geographic coordinate system, and broadcasts or displays the information except the position of the first road surface in the first abnormal information and the identifier of the first road corresponding to the first road surface, or broadcasts or displays the information except the position of the first road surface in the first abnormal information and the position of the first road surface on the first road.

When the first abnormality information is the second achievable manner described above, the pushing, by the vehicle, the abnormality of the first road surface to the user according to the first abnormality information may include: the vehicle displays the first abnormality information.
A road surface information detecting system configuration diagram according to this embodiment may be as shown in fig. 3. The system architecture comprises a detection device, a first road side device and a server. The detection equipment detects the first road to obtain first abnormal information, and sends the first abnormal information to the server to indicate the abnormal condition of the first road; the method comprises the steps that a server sends first abnormal information to first road side equipment located in a preset range of a first road surface; the first road side equipment broadcasts first abnormal information to vehicles within the coverage range of the first road side equipment. And after receiving the first abnormal information, the vehicle pushes the abnormal condition of the first road surface to the user.
In the embodiment, after the detection device detects the abnormal road surface, the detection device sends the abnormal information to the server, so that the server sends the abnormal information to the road side device in the preset range of the abnormal road surface, the road side device broadcasts the abnormal information to the vehicles in the coverage range of the road side device, the detection device is not required to be connected with more road side devices, the complexity of a road surface detection system can be reduced, and meanwhile, the server sends the abnormal information to the road side devices in the preset range of the abnormal road surface, and the probability that the vehicles which need to be notified of the abnormal information are not notified can be reduced.
When the detection device detects the road surface abnormality, there may be a false detection condition, for example, the road surface a is the road surface on the road a, the road surface a is normal, but the first abnormality information of the road surface a is detected, and after receiving the first abnormality information of the road surface a, a vehicle driving on the road a or a vehicle about to drive on the road a may change the driving route, which interferes with the normal operation of the vehicle. In order to solve the technical problem, the present embodiment is further improved on the basis of the previous embodiment. Fig. 4 is a second flowchart of the road surface information detection method provided in the embodiment of the present application, and referring to fig. 4, the method of the embodiment includes:
step S401, the detection device detects the first road to obtain first abnormal information, where the first abnormal information is used to indicate an abnormal condition of the first road.
The specific implementation of this step refers to the explanation in step S201, and is not described herein again.
Step S402, the detection device sends first abnormal information to the server.
The specific implementation of this step refers to the explanation in step S202, and is not described herein again.
And after the detection equipment obtains the first abnormal information, the first abnormal information is sent to the server.
Step S403, the server confirms that the first road is abnormal.
In one mode: the server confirms that the first path has the abnormality, and the method comprises the following steps: if the quantity of the abnormal information indicating the abnormal condition of the first road surface received by the server in the preset time range is larger than or equal to the preset quantity, the server confirms that the first road surface is abnormal.
The preset time range may include a time when the server receives the first abnormal information. For example, the preset time range is k hours before and after the time when the server receives the first abnormal information, and k is more than or equal to 0.1 and less than or equal to 0.5.
In another mode: the server confirms that the first path has the abnormality, and the method comprises the following steps: the server receives information of a first road surface sent by the terminal equipment; and the server confirms that the first road surface has abnormality according to the information of the first road surface.
Wherein, terminal equipment can be unmanned aerial vehicle, cell-phone, camera etc.. The information of the first road surface can be a picture of the first road surface, and the server analyzes the picture of the first road surface and confirms that the first road surface is abnormal. When the terminal device is a mobile phone, the information of the first road surface may also be information indicating that the first road surface is abnormal, which is input by a user.
In this way, after receiving the first abnormal information, the server can push the abnormal condition of the first road surface to the managed user according to the first abnormal information, after knowing that the managed user can acquire the information of the first road surface through the terminal device, and after acquiring the information of the first road surface, the terminal device sends the information of the first road surface to the server.
Step S404, the server sends first abnormal information to first road side equipment located in a preset range of the first road surface.
The specific implementation of this step refers to the explanation in step S203, and is not described herein again.

The method of the embodiment can reduce the complexity of the road surface detection system and reduce the probability that the vehicle needing to be notified of the abnormal information is not notified. In addition, the vehicle can be prevented from receiving wrong road surface abnormal information, and the normal operation of the vehicle is ensured.
When the detection device sends the abnormal information of the first road surface to the server, if there is no wireless network or a wireless network signal difference between the detection device and the server, the server may not receive the abnormal information of the first road surface in time, and thus the vehicle may not receive the abnormal information of the first road surface in time. Fig. 5 is a third flowchart of a road surface information detection method provided in the embodiment of the present application, and referring to fig. 5, the method of the embodiment includes:
step S501, the detection device detects the first road to obtain first abnormal information, where the first abnormal information is used to indicate an abnormal condition of the first road.

Step S502, the detection device sends the first abnormal information to a second road side device, and the second road side device is a road side device which establishes communication connection with the detection device. The communication connection established by the second roadside apparatus for the detection apparatus may be a wired connection or a wireless communication connection, and the wireless communication connection includes DSRC communication.
In this embodiment, after obtaining the first abnormal information, the detection device sends the first abnormal information to the second roadside device that establishes the communication connection, so that the second roadside device forwards the first abnormal information to the server.
When the detection device is a fixed detection device, the detection device may be in wired connection with a second roadside device having a wireless network or a position with good wireless network performance, so that when the position of the detection device does not have a wireless network or the wireless network is poor at the moment when the detection device detects the first abnormal information, the detection device may still send the first abnormal information to the second roadside device in real time, so that the second roadside device sends the first abnormal information to the server in real time.
When the detection equipment is mobile detection equipment, the detection equipment sends the first abnormal information to the roadside equipment which is close to the detection equipment through the wireless network, the roadside equipment sends the first abnormal information to the server in time, and the first abnormal information can be sent to the server in time when the wireless signal between the detection equipment and the server is poor or no wireless network exists.
When the detection device and the roadside device are both V2X devices, no matter whether the detection device is a mobile detection device or a fixed detection device, the detection device and the second roadside device can perform real-time short-distance communication through the DRSC technology, and the first abnormal information can still be sent to the server in time when the position of the detection device does not have a wireless network or the time when the detection device detects the first abnormal information is poor in wireless network.
In this embodiment, if the detection device is a V2X device, it is not necessary to establish wired communication between the detection device and the roadside device, which reduces the complexity of the road surface information detection system.
Step S503, the second road side equipment sends the first abnormal information to the server.
Step S504, the server sends first abnormal information to first road side equipment located in a preset range of the first road surface.
The explanation of the first road side device in the preset range of the first road surface refers to the explanation in step S203, and is not described herein again. It is understood that when the second road side device is also located within the preset range of the first road surface, the first road side device within the preset range of the first road surface includes the second road side device.
Step S505, the first road side equipment broadcasts first abnormal information to vehicles within the coverage range of the first road side equipment.
The specific implementation of this step refers to the explanation in step S204, and is not described here again.
A road surface information detecting system according to this embodiment is shown in fig. 6. Referring to fig. 6, the system architecture includes a detection device, a roadside device, and a server. The detection equipment detects the first road to obtain first abnormal information, and sends the first abnormal information to the server through the second road side equipment, wherein the first abnormal information is used for indicating the abnormal condition of the first road; the method comprises the steps that a server sends first abnormal information to first road side equipment located in a preset range of a first road surface; the first road side equipment broadcasts first abnormal information to vehicles within the coverage range of the first road side equipment. And after receiving the first abnormal information, the vehicle pushes the abnormal condition of the first road surface to the user.
The method of the embodiment can greatly reduce the probability that the vehicle to be notified of the abnormal information is not notified while reducing the complexity of the road surface detection system. In addition, the second road side equipment forwards the abnormal information of the first road surface to the server, and the server can be ensured to receive the abnormal information of the first road surface in time, so that the vehicle can receive the abnormal information of the first road surface in time, namely the road surface information detection efficiency is high, and the real-time performance is good.
Since the detection device may have a false detection condition when detecting a road surface abnormality, the present embodiment is further improved on the basis of the embodiment shown in fig. 5 in order to allow the vehicle to receive normal road surface information.
