Description

Technical Field

[0001] The present invention relates to the technical field of traffic control, and in particular to a road and railway intersection safety control system. Background Art

[0002] As transportation becomes more and more developed and there are more and more cars, there are more and more intersections between roads and railways. Since the railway is an early non-electrified railway, the route of the railway was also planned and completed earlier, and most of the roads were built later. This caused some problems, such as the soft soil roadbed reinforcement, pile foundation construction, stone blasting and roadbed settlement and roadbed stability caused by operating vehicles during road construction, as well as the displacement and deformation of the existing railway line structure. These changes involve safety issues, especially for railways. In the existing technology, railways and roads are monitored by levels or various sensors, but since most non-electrified railways are heavy-loaded railways and road construction has various vibrations, various sensors are very easy to damage and need to be replaced frequently, which is costly, and the level needs to be manually stared at for a long time, which is time-consuming and laborious. At the same time, the level cannot be monitored when vehicles are coming and going, which is very inconvenient.

[0003] Therefore, how to achieve long-term and lower-cost safety monitoring of highway and railway intersections is an urgent problem that needs to be solved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a road and railway intersection safety control system which can realize long-term and lower-cost safety monitoring of highway and railway intersections.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A road and railway intersection safety control system, comprising a control center, a thickness gauge, a drone and a satellite, wherein the control center comprises a controller, a control tower, a transmitting light source and a first communication module, the drone has a first imaging device and a second communication module communicating with the first communication module; the satellite has a second imaging device and a third communication module communicating with the first communication module;

[0007] When the road and railway intersection safety control system is working, the road and railway intersection that needs to be monitored are selected, the foundation of the road and the ground outside the foundation of the railway are selected as the installation surface, and the control tower is located on the installation surface; the rails and the road are corrected, and traffic markings prohibiting vehicles from crossing are respectively set on both sides of the corrected road surface, and a first reflecting surface is set on the traffic markings; two rails on the corrected railway are selected as the rail tops as the second reflecting surface; the first reflecting surface and the second reflecting surface are located on the same horizontal plane to form a "#" shape structure; a thickness gauge is used to continuously measure the thickness of the rails and the road to obtain an initial thickness value; the emitting light source is set on the top of the control tower and is set toward the first reflecting surface and the second reflecting surface;

[0008] The road and railway intersection safety prevention and control system performs a calibration action when working, and the calibration action includes: the emitting light source emits light to the corrected first reflection surface and the second reflection surface to form an initial reflection path through reflection, the controller communicates with the drone and the satellite through the first communicator, and controls the drone and the satellite to be on the reflection path; the reflected light forms a first initial image on the first imaging device of the drone and a second initial image on the second imaging device of the satellite; the emitting light source records the emission angle, and the drone records the spatial position of the drone when the first initial image is formed as the first spatial position; the satellite records the spatial position of the satellite when the second initial image is formed as the second spatial position; and when the second initial image obtains a "#"-shaped structure, the drone is located at the center of the "#";

[0009] The road and railway intersection safety control system performs several monitoring actions when working, and the monitoring actions include: using a thickness gauge to continuously measure the thickness of two rails of the railway and the roadbed to obtain thickness values, and uploading the thickness values ​​to the control center; the controller controls the emitting light source to emit light to the first reflecting surface and the second reflecting surface according to the emission angle, and at the same time controls the drone to reach the first spatial position and the satellite to reach the second spatial position, and forms a first monitoring image on the first imaging device of the drone and a second monitoring image on the second imaging device of the satellite; the thickness difference is subtracted from the initial thickness value to obtain the thickness difference, and if the thickness difference exceeds the preset range, the controller directly alarms; if the thickness difference is within the preset range, the controller compares the first monitoring image with the first initial image to determine whether the first monitoring image has missing, dim areas, or deformation, and if any of them exists, it is determined that there is partial settlement or deformation, and the controller directly alarms; if the thickness difference is within the preset range, the controller compares the second monitoring image with the second initial image to determine whether only the drone is photographed, and if so, it is considered that there is overall settlement, and if not, it is determined whether the drone is located at the center of "#", and if not, it is considered that there is overall settlement, and if both are yes, no action is taken.

[0010] Preferably, the drone further has a cleaning component, and before the monitoring action is performed, the controller controls the drone to fly above the first reflecting surface and the second reflecting surface to clean the first reflecting surface and the second reflecting surface.

[0011] Preferably, the first reflecting surface and the second reflecting surface are also provided with a self-cleaning coating.

[0012] Preferably, the drone also includes a machine nest adapted for the drone, and the machine nest is arranged on the control tower.

[0013] Preferably, the controller controls the monitoring action to be performed automatically.

[0014] Preferably, the control tower is also provided with a wind speed sensor and a rain sensor, and the controller determines whether it is necessary to automatically perform the monitoring action according to the wind speed sensor and the rain sensor.

[0015] Preferably, the road and railway intersection safety control system also includes a cloud, and the controller uploads the data of the drone and the satellite to the cloud through the first communication module, and the cloud controls the operation of the drone and the satellite by sending instructions to the first communication module.

[0016] Preferably, the drone also has a camera, and the drone takes pictures of the road surface and rails through the camera to obtain pictures and upload them to the controller, and the controller forwards the pictures to the cloud.

[0017] Preferably, the calibration work is re-performed after the road or railway is repaired or maintained.

[0018] Preferably, selecting the ground outside the foundation of the road or the foundation of the railway as the installation surface further includes: judging whether there is an obtuse angle between the railway and the road, and if so, selecting the ground corresponding to the obtuse angle as the installation surface; if both are right angles, randomly selecting the ground corresponding to any right angle as the installation surface; and the installation surface is located outside the foundation of the road or the foundation of the railway.

[0019] The beneficial effects of the present invention are as follows: by selecting the ground outside the foundation of the road and the foundation of the railway to install the control tower, the emitting light source thereon will not be affected by the road and the railway; and by utilizing the existing road marking lines as features, especially the traffic markings on both sides of the road that prohibit vehicles from crossing, which are rarely run over by vehicles in daily life, so the service life of the traffic markings is long, and they are located on both sides. If the middle is overloaded, the traffic markings on both sides that prohibit vehicles from crossing will be deformed and bulge, making the deformation characteristics more obvious; combined with the use of the top of the rail as the second reflecting surface, since the top of the rail is in a bright state due to friction with the rail during use and the railway is periodically maintained, the intersection with the road Most railways are non-electrified and naturally do not have overhead power supply networks. Therefore, there is no obstruction above such railways and they can be used as a good reflective surface. By utilizing or modifying existing structures, the modification cost is low and the durability is extremely strong. Combined with the fixed launch angle, the drone and the satellite are both on the reflection path, and the light source can be identified after one launch, without the need for two launches, which greatly improves efficiency. In addition, when using drones, since they are close to the ground, the initial correction purpose is to ensure that the first initial image is bright, which is convenient for comparison with subsequent images. The existence of missing or dim areas proves that the railway or road is tilted, deformed, or has partially settled. The principle is When railways and roads are tilted or deformed, the first and second reflective surfaces will be deformed or displaced. However, the control tower is independent and unaffected. The incident point remains unchanged, but the reflection point changes, and the reflection path must change, resulting in missing or dimming, indicating that there are problems with the first and second reflective surfaces. Combined with the feature that the position of the drone is controlled in the middle of the "#", because the first spatial position of the drone as a reference object is fixed, and the satellite is also in a fixed second spatial position, when the satellite takes pictures, as long as the position of the drone can be determined, it only needs to consider whether the position after the reflection of the "#" is correct, and it can directly determine whether the overall settlement is present, which greatly improves the accuracy. The efficiency of judgment is improved, while the difficulty of judgment is reduced, thereby reducing the cost of using satellites. It is only necessary to take a picture when the satellite passes through a fixed second space position, which is low in cost. In addition, satellites and drones can complement each other. If the satellite is too high, the accuracy of light reflection after passing through the atmosphere is insufficient, and it is difficult to identify slight local deformations. If the drone is too close to the ground, high accuracy can be guaranteed, but it is difficult to identify consistent overall settlement. Furthermore, through the thickness gauge, the most direct ground detection, once the thickness does not meet the standard, it directly affects the imaging of the drone and the satellite, so an alarm can be directly issued. The present application ensures the safety of road and railway intersections through integrated air-ground-space monitoring, with lower costs and simpler operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0026] Please refer to Figures 1 to 4 , a road and railway intersection safety control system, comprising a control center, a thickness gauge, a drone and a satellite, wherein the control center comprises a controller, a control tower, a transmitting light source and a first communication module, the drone has a first imaging device and a second communication module communicating with the first communication module; the satellite has a second imaging device and a third communication module communicating with the first communication module;

[0027] When the road and railway intersection safety control system is working, the road and railway intersection that needs to be monitored are selected, the foundation of the road and the ground outside the foundation of the railway are selected as the installation surface, and the control tower is located on the installation surface; the rails and the road are corrected, and traffic markings prohibiting vehicles from crossing are respectively set on both sides of the corrected road surface, and a first reflecting surface is set on the traffic markings; two rails on the corrected railway are selected as the rail tops as the second reflecting surface; the first reflecting surface and the second reflecting surface are located on the same horizontal plane to form a "#" shape structure; a thickness gauge is used to continuously measure the thickness of the rails and the road to obtain an initial thickness value; the emitting light source is set on the top of the control tower and is set toward the first reflecting surface and the second reflecting surface;

[0028] The road and railway intersection safety prevention and control system performs a calibration action when working, and the calibration action includes: the emitting light source emits light to the corrected first reflection surface and the second reflection surface to form an initial reflection path through reflection, the controller communicates with the drone and the satellite through the first communicator, and controls the drone and the satellite to be on the reflection path; the reflected light forms a first initial image on the first imaging device of the drone and a second initial image on the second imaging device of the satellite; the emitting light source records the emission angle, and the drone records the spatial position of the drone when the first initial image is formed as the first spatial position; the satellite records the spatial position of the satellite when the second initial image is formed as the second spatial position; and when the second initial image obtains a "#"-shaped structure, the drone is located at the center of the "#";

[0029] The road and railway intersection safety control system performs several monitoring actions when working, and the monitoring actions include: using a thickness gauge to continuously measure the thickness of two rails of the railway and the roadbed to obtain thickness values, and uploading the thickness values ​​to the control center; the controller controls the emitting light source to emit light to the first reflecting surface and the second reflecting surface according to the emission angle, and at the same time controls the drone to reach the first spatial position and the satellite to reach the second spatial position, and forms a first monitoring image on the first imaging device of the drone and a second monitoring image on the second imaging device of the satellite; the thickness difference is subtracted from the initial thickness value to obtain the thickness difference, and if the thickness difference exceeds the preset range, the controller directly alarms; if the thickness difference is within the preset range, the controller compares the first monitoring image with the first initial image to determine whether the first monitoring image has missing, dim areas, or deformation, and if any of them exists, it is determined that there is partial settlement or deformation, and the controller directly alarms; if the thickness difference is within the preset range, the controller compares the second monitoring image with the second initial image to determine whether only the drone is photographed, and if so, it is considered that there is overall settlement, and if not, it is determined whether the drone is located at the center of "#", and if not, it is considered that there is overall settlement, and if both are yes, no action is taken.

[0030] From the above description, it can be seen that by installing the control tower on the ground outside the foundation of the road or the railway, the emitting light source thereon will not be affected by the road or the railway; and by utilizing the existing road marking lines as features, especially the traffic markings on both sides of the road that prohibit vehicles from crossing, which are seldom run over by vehicles in daily life, the traffic markings have a long service life, and are located on both sides. If the middle is overloaded, the traffic markings on both sides that prohibit vehicles from crossing will be deformed and bulge, making the deformation characteristics more obvious; combined with the use of the top of the rail as the second reflective surface, since the top of the rail is in a bright state due to friction with the rail during use and the railways are periodically maintained, most railways that intersect with roads It is a non-electrified railway, so there is naturally no overhead power supply network. Therefore, there is no obstruction above this type of railway, and it can be used as a good reflective surface. By utilizing or modifying existing structures, the modification cost is low and the durability is extremely strong. Combined with the fixed launch angle, the drone and the satellite are both on the reflection path, and the light source can be identified after one launch, without the need for two launches, which greatly improves efficiency. In addition, when using drones, since they are close to the ground, the initial correction purpose is to ensure that the first initial image is bright, which is convenient for comparison with subsequent images. The existence of missing or dim areas proves that the railway or road is tilted, deformed, or has partially settled. The principle is that the railway When the road is tilted or deformed, the first and second reflection surfaces will be deformed or displaced, while the control tower is independent and unaffected. The incident point remains unchanged, but the reflection point changes, and the reflection path must change, resulting in missing or dimming, indicating that there are problems with the first and second reflection surfaces. Combined with the feature that the position of the drone is controlled in the middle of the "#", because the first spatial position of the drone as a reference object is fixed, and the satellite is also a fixed second spatial position, when the satellite takes a photo, as long as the position of the drone can be determined, it only needs to consider whether the position after the reflection of the "#" is correct, and it can directly determine whether the overall settlement is present, which greatly improves The efficiency of judgment is improved, and the difficulty of judgment is reduced, thereby reducing the cost of using satellites. It is only necessary to take a picture when the satellite passes through a fixed second space position, which is low in cost. In addition, satellites and drones can complement each other. If the satellite is too high, the accuracy of light reflection after passing through the atmosphere is insufficient, and it is difficult to identify slight local deformations. If the drone is too close to the ground, high accuracy can be guaranteed, but it is difficult to identify consistent overall settlement. Furthermore, through the thickness gauge, the most direct ground detection, once the thickness does not meet the standard, it directly affects the imaging of the drone and satellite, so an alarm can be directly issued. The present application ensures the safety of road and railway intersections through integrated air-ground-space monitoring, and the cost is lower and the operation is simpler.

[0031] Furthermore, the drone also has a cleaning component. Before the monitoring action is performed, the controller controls the drone to fly above the first reflecting surface and the second reflecting surface to clean the first reflecting surface and the second reflecting surface.

[0032] From the above description, it can be seen that by cleaning the first reflective surface and the second reflective surface through the cleaning component, the subsequent imaging effect can be guaranteed, the recognition accuracy can be improved, and the functions of the drone can be further developed.

[0033] Furthermore, the first reflecting surface and the second reflecting surface are also provided with a self-cleaning coating.

[0034] From the above description, it can be seen that by setting the self-cleaning coating, e.g. The self-cleaning coating can ensure the reflective effect and improve recognition.

[0035] Furthermore, the drone also includes a machine nest adapted for the drone, and the machine nest is arranged on the control tower.

[0036] From the above description, it can be seen that by setting up a drone nest, the drone can be recharged, watered, and other operations can be performed, which improves convenience and does not require the assistance of a dedicated pilot.

[0037] Furthermore, the controller controls the monitoring action to be automatically executed.

[0038] From the above description, it can be seen that since the position of the machine nest is determined, the first spatial position is determined, the second spatial position is determined, and the position of the emitting light source is fixed, automatic operation can be achieved, greatly improving efficiency.

[0039] Furthermore, the control tower is also provided with a wind speed sensor and a rain sensor, and the controller determines whether it is necessary to automatically perform the monitoring action according to the wind speed sensor and the rain sensor.

[0040] From the above description, it can be seen that through the wind speed sensor and the rain sensor, for example, if the real-time wind speed is level 7, which exceeds the wind strength at which the drone can work, it will not be executed. If it is raining heavily, which also exceeds the wind strength at which the drone can work, it will not be executed.

[0041] Furthermore, the road and railway intersection safety control system also includes a cloud, and the controller uploads the data of the drone and the satellite to the cloud through the first communication module, and the cloud controls the operation of the drone and the satellite by sending instructions to the first communication module.

[0042] From the above description, it can be seen that through the cloud, one cloud can control the intersections of multiple roads and railways, greatly reducing labor costs, while realizing data management and data aggregation, further improving safety and control performance, such as achieving safety and control along the entire railway line.

[0043] Furthermore, the drone also has a camera, and the drone takes pictures of the road surface and rails through the camera to obtain pictures and upload them to the controller, and the controller forwards the pictures to the cloud.

[0044] From the above description, we can see that through the cloud, the conditions of the road surface and rails can be judged, and if damage occurs, repairs can be arranged in a timely manner.

[0045] Furthermore, if the road or railway is repaired or maintained, the calibration work is carried out again.

[0046] From the above description, it can be seen that through recalibration, since calibration will be performed after repair or maintenance, there is no need to recalibrate, only recalibration is required.

[0047] Furthermore, selecting the ground outside the foundation of the road and the foundation of the railway as the installation surface further includes: judging whether there is an obtuse angle between the railway and the road, if so, selecting the ground corresponding to the obtuse angle as the installation surface, and if both are right angles, randomly selecting the ground corresponding to any right angle as the installation surface; and the installation surface is located outside the foundation of the road and the foundation of the railway.

[0048] From the above description, it can be seen that by choosing the ground corresponding to the obtuse angle as the installation surface, due to the openness, the foundation of the installation surface can be farther away from the foundation of the road and the foundation of the railway, and thus the impact of the road and the railway on the control tower is lower; however, the "#" is tilted a little, even 45°, but the principle is the same.
