[0002] Road collapse can cause serious problems in the safety of life and property, especially at night and on highways, where the driver's field of vision is limited, the vehicle is traveling at a high speed, and the driver has no time to react, which may cause serious consequences. If the collapse can be discovered in time and the corresponding information can be sent to the car owners and relevant personnel of the road section in time when it occurs or before it occurs, serious casualties can be avoided. Therefore, road collapse warning is very important. At present, when monitoring collapse, it can only be detected when there is a serious position anomaly at the collapse location. It cannot detect minor anomalies, and it cannot locate the abnormal points. The space, length, and types of anomalies that can be detected are very limited. Therefore, how to detect the possibility of road collapse in advance and quickly locate the collapse location is a problem that needs to be solved urgently. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] At present, when monitoring landslides, only serious position anomalies can be detected at the landslide location, and minor anomalies cannot be detected, and the abnormal point cannot be located. The space, length, and type of anomalies that can be detected are very limited. In order to solve the above technical problems, the present application discloses a road landslide monitoring method, which can detect the possibility of road landslides in advance and quickly locate the landslide location.

[0045] See also Figure 1 As shown, an embodiment of the present invention discloses a road collapse monitoring method, which is applied to a monitoring device located at a monitoring point, including:

[0046] Step S11, using a preset channel quality detector to check the first target optical fiber to determine whether the channel quality of the first target optical fiber has changed, generating a corresponding abnormal signal when the degree of change in the channel quality of the first target optical fiber meets a preset condition, and analyzing the abnormal signal to obtain a corresponding optical fiber abnormality cause analysis result.

[0047] In this embodiment, the preset channel quality detector can be an OTDR (Optical Time-Domain Reflectometer), that is, the first target optical fiber is used to monitor abnormal conditions of the road before the landslide, and the preset channel quality detector is used to check the first target optical fiber to determine whether the channel quality of the first target optical fiber has changed, including: using an optical time domain reflectometer to check the first target optical fiber to determine whether the channel quality of the first target optical fiber has changed. If the first target optical fiber is laid from point A to point B, the OTDR at point A can, through related work, instantly analyze whether there is any abnormality in the entire first target optical fiber from point A to point B, such as bending, breakage, water seepage, etc., and at the same time analyze the location of the abnormality, that is, indirectly judge the condition of the road by observing the condition of the first target optical fiber. Figure 2 As shown, if the channel quality of the first target optical fiber changes and the degree of change meets the preset conditions, a corresponding abnormal signal will be generated. By analyzing the abnormal signal, the cause of the abnormal signal can be determined, that is, the result of the optical fiber abnormality cause analysis.

[0048] Step S12, communicating and transmitting with a preset signal receiving and responding device on the second target optical fiber through the second target optical fiber, and determining whether a landslide occurs on the target monitoring road corresponding to the monitoring point and a preliminary landslide position corresponding to the landslide when the landslide occurs based on the corresponding communication transmission results.

[0049] In this embodiment, Figure 3 As shown, the first target optical fiber (i.e., optical fiber 1) and the second target optical fiber (i.e., optical fiber 2) are both laid on the target monitoring road, and the second target optical fiber can communicate and transmit with the preset signal receiving and responding device on the second target optical fiber, and determine whether a landslide occurs on the target monitoring road corresponding to the monitoring point and the corresponding preliminary landslide position when a landslide occurs based on the corresponding communication transmission results. Specifically, Figure 4 As shown, the communication transmission is performed with the preset signal receiving and answering device on the second target optical fiber through the second target optical fiber, including: sending a question and answer signal through the second target optical fiber to obtain a target answer signal sent by each of the preset signal receiving and answering devices on the second target optical fiber. The preset receiving and answering devices may be some sensor devices, which are located at signal receiving and answering points set at preset distances (such as one kilometer, which may be longer or shorter) on the target monitoring road, and do not affect each other.

[0050] In a specific implementation, if the monitoring device at the monitoring point can obtain the target response signals sent by all preset signal receiving and responding devices on the target monitoring road corresponding to the monitoring point, it can be determined that the target monitoring road corresponding to the monitoring point has not collapsed. If the target response signals sent by all preset signal receiving and responding devices are not obtained, the preset signal receiving and responding device corresponding to the target response signal that has not been obtained is determined as a target abnormal device, and based on the target position corresponding to the target abnormal device, it is determined whether the target monitoring road corresponding to the monitoring point has collapsed and the initial collapse position corresponding to the collapse when the collapse occurs. Wherein, based on the target position corresponding to the target abnormal device, determining whether the target monitoring road corresponding to the monitoring point has collapsed and the initial collapse position corresponding to the collapse when the collapse occurs may specifically include: if the target abnormal device closest to the monitoring point and all preset signal receiving and responding devices in the far direction of the monitoring point are target abnormal devices, then the road section between the target abnormal device closest to the monitoring point and the preset signal receiving and responding device farthest from the monitoring point and capable of returning the target response signal normally is determined as the initial collapse position.

[0051] That is to say, Figure 4 As shown, in order to improve the utilization efficiency of the equipment and increase the monitoring length, point A can be set as a monitoring point in the middle of the road section to be monitored, and the monitoring equipment can be deployed. Then the monitoring equipment at point A can simultaneously monitor the preset signal receiving and answering devices on the target monitoring roads in both directions. Under normal circumstances, the monitoring equipment at point A can obtain the target response signals sent by the preset signal receiving and answering devices a to m. If a landslide occurs between the preset signal receiving and answering device f and the preset signal receiving and answering device g, the second target optical fiber will be interrupted in the landslide section, resulting in the monitoring equipment at monitoring point A being unable to obtain the response signals sent by the preset signal receiving and answering devices a to f, that is, unable to communicate with them. Then the preset signal receiving and answering devices a to f can be used as target abnormal devices, and the road section between the preset signal receiving and answering device g and the target abnormal device f can be used as the preliminary landslide location. It can be understood that some roads that need to be monitored may be relatively long and have complex road structures. In this case, one monitoring point can monitor multiple channel roads at the same time, and cross-monitoring can be flexibly distributed, not limited to a single point-to-point.

[0052] In addition, if Figure 5As shown, if there are no less than two monitoring points on the road where the optical fiber is located, such as there are preset signal receiving and answering devices 1 to 21 between monitoring point A and monitoring point B, and both monitoring points can obtain the target response signals sent by all preset signal receiving and answering devices under normal circumstances, if the second target optical fiber between the preset signal receiving and answering device 10 and the preset signal receiving and answering device 11 is disconnected, the monitoring device at monitoring point A cannot receive the target response signals sent by the preset signal receiving and answering devices after the preset signal receiving and answering device 10, and the monitoring device at monitoring point B cannot receive the target response signals sent by the preset signal receiving and answering devices before the preset signal receiving and answering device 11, so it can be determined that the road section between the preset signal receiving and answering device 10 and the preset signal receiving and answering device 11 has collapsed. At the same time, if the monitoring devices at monitoring point A and monitoring point B cannot obtain the target response signals sent by the preset signal receiving and answering device 18, but can obtain the target response signals sent by the preset signal receiving and answering devices 17 and 19, it means that the preset receiving and answering device 18 may be faulty. Of course, for the same section of road, it is not limited to setting only two monitoring points A and B. It should be based on actual conditions, such as setting them at various highway intersections, cross-monitoring, to improve timeliness and accuracy. It is understandable that if the range of the target monitoring road corresponding to monitoring point A and monitoring point B overlaps, both monitoring points can be set to monitor the overlapping part.

[0053] In this embodiment, in order to ensure the accuracy of the collapse judgment result, before using the preset channel quality detector to check the first target optical fiber to determine whether the channel quality of the first target optical fiber has changed, it can also include: determining the protective tube material of the first target optical fiber and the second target optical fiber based on the geological properties of the target monitoring road, so as to process the first target optical fiber and the second target optical fiber with the protective tube material based on the preset protective tube structure and lay them on the target monitoring road. Figure 6 As shown, for the convenience of maintenance and installation, the preset signal receiving and answering equipment at each point does not need to be buried under the roadbed. The signal line is pulled out and the equipment is installed on the roadside. Each device is connected in parallel and powered independently without interfering with each other. At the same time, in order to avoid the impact and damage to the line during normal use of the road, such as false disconnection and other problems, the laying depth of the line can be controlled at about 50cm according to the actual situation of the road. The specific adjustment is not limited to the 50cm mentioned in the figure according to the actual situation. The data in the figure is only for reference. In addition, the signal type and transmission frequency on the optical fiber need to meet the requirements that each answering point can receive the signal, and because it needs to work all the time, the transmission frequency can be appropriately reduced to reduce power consumption.

[0054] In this embodiment, the target monitoring road is determined according to the actual situation. For example, some roads are all rocky and soil, with good drainage systems around them, plain landforms, and no height difference. After comprehensive evaluation, there is no risk and possibility of landslides, so roads with better conditions do not need to be processed. On the contrary, roads with poor environment and conditions are all ordinary soil underneath, with poor drainage systems around them, with height differences up and down, and streams and rivers. It is estimated that there will be a risk of landslides. Road sections under these conditions need to be laid with a monitoring system, that is, the target monitoring road. In addition, optical fiber as a transmission medium has many advantages, such as long transmission distance (tens or hundreds of kilometers), low transmission loss, strong anti-interference ability, low cost, easy connection and laying, etc., which enables this embodiment to ensure monitoring of a larger range of lengths at a lower cost.

[0055] In this embodiment, Figure 7 As shown, the optical fiber line is wrapped in a protective tube, and some small holes are set on the wall of the protective tube to monitor the water ingress due to road breaks. The optical fiber and the protective tube are fixed together with glue every 50 cm in the pipeline. On the one hand, the interior of the pipeline is isolated and partitioned. If water ingress occurs in certain areas due to breaks, it will not flow to the unbroken areas and cause misjudgment. On the other hand, when a landslide occurs, the optical fiber line is pulled and disconnected. Fixing it together with the protective tube with glue can ensure that the circuit is broken only at the landslide as much as possible, without causing the entire optical fiber to be stressed, making it impossible to determine the location of the optical fiber disconnection. Figure 8 The figure shows the external structure of the optical fiber protection tube. There is a 5cm high protruding structure every 50cm and it is connected to the protection tube. This structure can ensure that the line is fixed in position after laying and firmly stuck in the concrete. When the foundation breaks, sinks, or collapses, it can pull the channel to deform, thereby ensuring that changes in channel quality can be monitored. It should be pointed out that there are corresponding requirements for the material of the protection tube. When the road surface collapses, the line will break with the collapse, or be severely bent. Therefore, the toughness of the pipeline material cannot be particularly good, otherwise it will not be able to disconnect, and it cannot be too poor, which will lead to quality problems. It is necessary to evaluate the abnormal conditions of the road surface and the destructive force generated, and select the material based on the evaluation.

[0056] Step S13, correcting the preliminary collapse position based on the optical fiber abnormality cause analysis result to determine a corrected collapse position and sending the corrected collapse position to a target platform so that the target platform performs corresponding collapse warning operations based on the corrected collapse position.

[0057] In this embodiment, after the second target optical fiber is used to determine the road section where the landslide occurs, that is, after the preliminary landslide location is obtained, since the first target optical fiber and the second target optical fiber are both laid on the target monitoring road, Figure 2As shown, the initial collapse position can be corrected by combining the type and position of the optical fiber anomaly determined by the optical fiber anomaly cause analysis result obtained by the first target optical fiber to obtain the corrected collapse position. Since the processing speed of optical fiber anomaly detection and analysis using an optical time domain reflectometer in the prior art is slow, the optical fiber anomaly cause analysis result is only used to predict collapse and correct the initial collapse position. The initial collapse position is quickly determined using the second target optical fiber. By combining the two, the corrected collapse position can be quickly obtained. Simultaneous monitoring of the two lines can provide higher accuracy.

[0058] It should be pointed out that in this embodiment, there may be an abnormal signal returned by the first target optical fiber and an analysis result of the cause of the optical fiber abnormality, but the communication transmission result returned by the second target optical fiber indicates that the target monitoring road corresponding to the monitoring point has not collapsed. This is because the first target optical fiber can predict what kind of abnormal state occurs at any position of the entire optical fiber before the collapse, and give a corresponding judgment (that is, the result of the analysis of the cause of the optical fiber abnormality); and before the collapse or other failures occur in the second target optical fiber, the monitoring point will receive a reply from the signal receiving and answering point, and the second target optical fiber will feedback as normal. The combination of the two signals is to make a comprehensive data analysis of the same monitoring point range. The advance prediction of the first target optical fiber plus the monitoring point response reply of the second target optical fiber can more clearly determine whether the target monitoring road of the monitoring point is in a state before a collapse or has already collapsed in a certain period of time, so as to better implement the corresponding early warning and rescue measures. The result of the analysis of the cause of the optical fiber abnormality obtained in this case can also be used to correct the initial collapse position after the collapse occurs.

[0059] In this embodiment, Fig. 9 As shown in the figure, each monitoring point is equipped with a wireless upload device. When the monitoring point confirms that it has received abnormal information, it can be uploaded to the target platform through the wireless device. After receiving the information, the target platform quickly processes it and updates the relevant road collapse information to the map or navigation platform through the 4G network or wired form, and then sends it to relevant personnel through navigation software and text messages. The information is quickly sent between various platforms, and the platform sends it to the car owner at the same time. The multi-platform reception and transmission ensures coverage and avoids missed messages. After receiving the message, the car owner on the road can make preparations in advance to achieve the purpose of rapid and accurate early warning, thereby realizing rapid early warning for traffic participants and reducing traffic casualties.

[0060] It can be seen that the present application utilizes a preset channel quality detector to monitor the channel quality of the first target optical fiber in real time to determine whether the target monitoring road has any abnormalities that occurred before the landslide, such as breakage, sinking, displacement, water seepage, etc.; communicates and transmits with a preset signal receiving and responding device on the second target optical fiber through the second target optical fiber, and determines whether a landslide has occurred on the target monitoring road corresponding to the monitoring point and the corresponding preliminary landslide position when the landslide occurs based on the corresponding communication transmission results, and uses the optical fiber abnormality cause analysis results to correct the preliminary landslide position to obtain an accurate corrected landslide position. After obtaining the corrected landslide position, the target platform can perform corresponding landslide warning operations, thereby realizing the possibility of early detection of road landslides and rapid positioning of the landslide position.

[0064] The early warning operation execution module 13 is used to correct the preliminary collapse position based on the optical fiber abnormality cause analysis result to determine the corrected collapse position and send the corrected collapse position to the target platform, so that the target platform performs a corresponding collapse early warning operation based on the corrected collapse position;

[0065] Wherein, the first target optical fiber and the second target optical fiber are both laid on the target monitoring road.
