Description

Technical Field

[0001] This application relates to the field of railway safety, and particularly to a geological disaster monitoring and forecasting system along railway lines. Background Art

[0002] Geological disasters refer to collapses, landslides, debris flows, ground fissures, as well as earthquakes, volcanic eruptions, etc. formed either artificially or naturally. Geological disasters can cause serious ground damage and pose greater risks to the railway along the line.

[0003] For this reason, some geological disaster forecasting systems along railway lines have emerged. These systems use a host computer to statistically collect the monitoring situations along the railway line, and observe the road surface and railway conditions through these monitoring pictures to ensure the safety of railway traffic. At the same time, the railway will also dispatch patrol cars to conduct safety patrol work on the railway.

[0004] However, there are too many monitoring pictures and it is difficult to observe whether there is a specific movement, making it difficult to judge whether a geological disaster exists or occurs, resulting in inadequate care and still having certain potential safety hazards. Utility Model Content

[0005] This application provides a geological disaster monitoring and forecasting system along railway lines for ensuring the safety of railway traffic.

[0006] This application provides a geological disaster monitoring and forecasting system along railway lines, including a host computer and disaster monitoring components. The host computer has an alarm. The disaster monitoring components are set as multiple, and the disaster monitoring components are arranged on one side of the railway. The multiple disaster monitoring components are spaced apart along the extension direction of the railway. The disaster monitoring components further include embedded parts, sensors, and communicators. Among them, the embedded parts are buried underground on one side of the railway, the sensors are arranged on one side of the embedded parts and are in contact with the embedded parts, the communicators are fixedly connected to the embedded parts, the communicators are electrically connected to the sensors, and the communicators are communicatively connected to the host computer.

[0007] The disaster monitoring components in this application are arranged beside the railway. At the same time, the embedded parts are in contact with the sensors. The relative position between the embedded parts and the sensors can be used to judge whether there is a geological disaster in this area. When a geological disaster occurs, relative displacements will occur between the embedded parts and the sensors in all the disaster monitoring components in this area. The communicator can transmit the detection information of the sensors to the host computer, and the host computer controls the alarm to achieve the alarm effect. When a geological disaster occurs, the staff can adjust the railway route in time according to the early warning information and dispatch patrol cars for maintenance, thus providing further protection for railway safety.

[0008] In some embodiments of the present application, the embedded part includes a bottom plate and a side plate. The bottom plate is fixedly connected to the side plate, and an included angle is formed between the bottom plate and the side plate. A groove is provided on the wall surface of the bottom plate facing the side plate, and the sensor is movably arranged in the groove. The bottom plate and the side plate are fixedly connected and an included angle is formed therebetween. At this time, no matter which direction is used for embedding, the embedded part can be better fixed, which is beneficial to improving the stability of the embedded part.

[0009] In some embodiments of the present application, the embedded part further includes an elastic contact plate. The elastic contact plate is arranged on the wall surface of the side plate facing the bottom plate, and the detection probe of the sensor abuts against the elastic contact plate. When the train travels on the railway, the railway will vibrate to a certain extent. The elastic contact plate can absorb this part of the vibration to prevent the sensor from giving false alarms.

[0010] In some embodiments of the present application, the detection probe of the sensor is elastic and in a compressed state, so that the detection probe resets after the sensor is separated from the embedded part. This solution uses an elastic compression method for contact. When the probe of the sensor resets, it indicates that the sensor is separated from the embedded part. At this time, the sensor can send a signal and the communicator transmits the signal, so that the upper computer receives the signal and gives an alarm.

[0011] In some embodiments of the present application, multiple disaster monitoring components are arranged on the same side of the railway. The scope of geological disasters is relatively large. Therefore, only by arranging disaster monitoring components on one side of the railway can the corresponding geological disaster detection effect be achieved.

[0012] In some embodiments of the present application, disaster monitoring components are arranged on both sides of the railway. Arranging disaster monitoring components on both sides of the railway can make the geological disaster monitoring more accurate.

[0013] In some embodiments of the present application, along the extension direction of the railway, the distance between two adjacent disaster monitoring components is the same. This solution can stably detect the railway and can provide good protection for each section of the railway.

[0014] In some embodiments of the present application, the distance between the disaster monitoring component and the railway is 0.5m - 2m. This distance can reduce the vibration caused by the passing of the train, and at the same time can ensure the detection results of geological disasters along the railway.

[0015] In some embodiments of the present application, the geological disaster monitoring and forecasting system along the railway further includes a waterproof box. The waterproof box is arranged on the embedded part, the communicator and the sensor are arranged in the waterproof box, and the probe of the sensor penetrates through the waterproof box. The waterproof box can provide waterproof protection for the communicator and the sensor buried underground, which helps to ensure the normal operation of the disaster monitoring component.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0021] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0022] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0023] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations. In addition, when describing pipelines, the terms "connected" and "connected" used in the present application have the meaning of conducting. The specific meaning needs to be understood in combination with the context.

[0024] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0025] Geological disasters refer to collapses, landslides, debris flows, ground fissures, as well as earthquakes, volcanic eruptions, etc. formed by humans or nature. Geological disasters will bring serious ground damage and pose greater risks to the railways along the line.

[0026] For this reason, some geological disaster prediction systems along railways have emerged. These systems use a host computer to statistically collect the monitoring conditions along the railway, and observe the road surface conditions and railway conditions through these monitoring screens to ensure the safety of railway transportation. At the same time, the railway will also dispatch patrol cars to conduct safety patrols on the railway.

[0027] However, the monitoring screens still need to be watched and analyzed manually. Since the incidence rate of geological disaster accidents is extremely low, most of the staff are part-time, and it is easy to get distracted and the care is not in place. At the same time, no corresponding camera structures are set around the railways in mountainous areas, tunnels and other regions. Therefore, there are still certain potential safety hazards in railway transportation.

[0028] For this reason, please refer to Figure 1 , the present application provides a geological disaster monitoring and prediction system along a railway 3, including a host computer 1 and a disaster monitoring component 2.

[0029] Please refer to Figure 1 , the host computer 1 has an alarm 11. The host computer 1 can be a server, or a conventional computer or other structures with communication functions and information processing functions; the alarm 11 can be an electronic alarm 11, or a buzzer or other structures with alarm functions.

[0030] Please refer to Figure 1 , a plurality of disaster monitoring components 2 are provided. The disaster monitoring components 2 are arranged on one side of the railway 3, and the plurality of disaster monitoring components 2 are spaced apart along the extension direction of the railway 3. Since the railway 3 is relatively long, the number of disaster monitoring components 2 can be set according to the length of the railway 3. At this time, the plurality of disaster monitoring components 2 can be commonly connected to a host computer 1 for communication, or a plurality of host computers 1 can be set, and the disaster monitoring components 2 are distinguished according to the position or the railway 3, so that the disaster monitoring components 2 in different partitions are connected to different host computers 1.

[0031] Please refer to Figure 1, the disaster monitoring component 2 further includes an embedded part 21, a sensor 22, and a communicator 23. Among them, the embedded part 21 is buried underground on one side of the railway 3, the sensor 22 is arranged on one side of the embedded part 21 and is in contact with the embedded part 21, the communicator 23 is fixedly connected to the embedded part 21, the communicator 23 is electrically connected to the sensor 22, and the communicator 23 is communicatively connected to the upper computer 1.

[0032] In this application, the disaster monitoring component 2 is arranged beside the railway 3. At the same time, the embedded part 21 is in contact with the sensor 22. Whether there is a geological disaster in this area can be judged by the relative position between the embedded part 21 and the sensor 22. When a geological disaster occurs, relative displacements will occur between the embedded parts 21 and the sensors 22 in all the disaster monitoring components 2 in this area. The communicator 23 can transmit the detection information of the sensor 22 to the upper computer 1, and the upper computer 1 controls the alarm 11 to achieve the alarm effect. When a geological disaster occurs, the staff can adjust the railway 3 route in time according to the early warning information and send inspection vehicles for maintenance, so as to further ensure the safety of the railway 3.

[0033] Please refer to Figure 1 , in some examples, the embedded part 21 is used to be buried underground. There are stones piled on the railway 3. The embedded part 21 can be buried under the stones or outside the stones.

[0034] Please refer to Figure 1 , since the embedded part 21 is buried underground, the embedded part 21 can have good physical properties. For example, it can be made of iron, and at the same time, an anti-corrosion coating can be applied to the surface of the embedded part 21 to improve its performance.

[0035] Alternatively, the embedded part 21 can also be made of non-metallic material, such as hard plastic, which can also meet the usage requirements.

[0036] Please refer to Figure 1 , in some examples, the sensor 22 can be a displacement sensor 22, and the displacement amount between the embedded part 21 and the sensor 22 can be detected by the displacement sensor 22.

[0037] Or it can also be a pressure sensor 22. A contact method and a pressure value can be preset between the embedded part 21 and the sensor 22. When the pressure value drops suddenly, it can indicate that a large relative displacement has occurred between the embedded part 21 and the sensor 22.

[0038] Please refer to Figure 1 , in some examples, multiple groups of disaster monitoring components 2 can be the same or partially the same.

[0039] In some examples, the communicator 23 can be a satellite communicator, or a 4G communicator or a 5G communicator, or other wireless communicators.

[0040] In some examples, both the sensor 22 and the communicator 23 require electrical energy to operate. Therefore, a buried line can be laid underground to ensure the normal operation of the disaster monitoring component 2. Alternatively, a battery can be installed within the disaster monitoring component 2. Since the power consumption of the sensor 22 and the communicator 23 is not high, a conventional lithium battery can maintain their long-term operation. Then, the purpose of maintaining the operation of the disaster monitoring component 2 can be achieved by regularly replacing the battery.

[0041] Please refer to Figure 2 , in some examples, the embedded part 21 includes a bottom plate 211 and a side plate 212. The bottom plate 211 is fixedly connected to the side plate 212, and an included angle is formed between the bottom plate 211 and the side plate 212. A groove 213 is provided on the wall surface of the bottom plate 211 facing the side plate 212, and the sensor 22 is movably arranged within the groove 213. The bottom plate 211 and the side plate 212 are fixedly connected and an included angle is formed therebetween. At this time, no matter which direction of burial is adopted, the embedded part 21 can be better fixed, which is beneficial to improving the stability of the embedded part 21.

[0042] Please refer to Figure 2 , in some examples, the bottom plate 211 and the side plate 212 can be integrally formed, such as by casting, or can also be formed by bending, or can also be other additive manufacturing methods, such as welding, bolt connection, etc.

[0043] Please refer to Figure 2 , in some examples, the bottom plate 211 and the side plate 212 can be of equal size, or can have equal thickness, or can also be of the same material.

[0044] Please refer to Figure 2 , in some examples, the depth of the groove 213 can be 1 cm to achieve a simple positioning function, and at the same time, it will not have too much fixing effect on the sensor 22 to affect the detection performance.

[0045] Please refer to Figure 2 , in some examples, the included angle between the bottom plate 211 and the side plate 212 can be between 30° and 120°, preferably 90°.

[0046] Please refer to Figure 2 , in some examples, the embedded part 21 further includes an elastic contact plate 24. The elastic contact plate 24 is arranged on the wall surface of the side plate 212 facing the bottom plate 211, and the detection probe 221 of the sensor 22 abuts against the elastic contact plate 24. When the train travels on the railway 3, the railway 3 will vibrate to a certain extent. The elastic contact plate 24 can absorb this part of the vibration to prevent the sensor 22 from giving false alarms.

[0047] Please refer to Figure 2, in some examples, the elastic contact plate 24 can be a plush layer combined with an acrylic plate, or it can also be a rubber plate, both of which can meet the usage requirements.

[0048] In some examples, the elastic plate can be embedded in the side plate 212 or adhered to the side plate 212.

[0049] Please refer to Figure 2 , in some examples, the detection probe 221 of the sensor 22 is elastic and in a compressed state, so that the detection probe 221 can reset after the sensor 22 is separated from the embedded part 21. This solution uses an elastic compression method for contact. When the probe of the sensor 22 resets, it indicates that the sensor 22 is separated from the embedded part 21. At this time, the sensor 22 can send a signal and the communicator 23 can transmit this signal, so that the host computer 1 can receive the signal and give an alarm.

[0050] Please refer to Figure 2 , in some examples, in order to prevent soil from sticking to the probe and making it difficult for the probe to reset, a housing can be provided on the elastic part of the probe. The housing abuts between the elastic plate and the sensor 22, and the probe is elastically arranged inside the housing, so that the elastic effect of the probe can take effect normally.

[0051] In some examples, the compressed state can make the sensor 22 have a certain pressure value or initial displacement, which is helpful for disaster monitoring.

[0052] Please refer to Figure 2 , in some examples, multiple disaster monitoring components 2 are arranged on the same side of the railway 3. The range of geological disasters is relatively large, so only by arranging the disaster monitoring components 2 on one side of the railway 3 can the corresponding geological disaster detection effect be achieved.

[0053] In some other examples, disaster monitoring components 2 are arranged on both sides of the railway 3. Arranging disaster monitoring components 2 on both sides of the railway 3 can make the geological disaster monitoring more accurate.

[0054] Please refer to Figure 2 , in some examples, along the extension direction of the railway 3, the spacing between two adjacent disaster monitoring components 2 is the same. This solution can stably detect the railway 3 and can provide good protection for each section of the railway 3.

[0055] Please return to refer to Figure 1 , in some examples, the spacing between two adjacent disaster monitoring components 2 can be 500 m, or it can also be 50 m or 2000 m.

[0056] For areas prone to danger, the distribution of the disaster detection components can be relatively dense, such as in tunnels and mountains. At this time, the spacing between two adjacent disaster monitoring components 2 in this part can be the same, and at the same time, it can be different from the spacing between the disaster monitoring components 2 installed in the plain area.

[0057] In some examples, the spacing between the disaster monitoring component 2 and the railway 3 is 0.5m - 2m. This spacing can reduce the vibration caused by the passing of the train, and at the same time, it can also ensure the detection results of geological disasters along the railway 3.

[0058] Please continue to refer to Figure 1 , in some examples, the spacing between the disaster monitoring component 2 and the railway 3 can be understood as the horizontal spacing. Through this distance, the impact caused by the passing of the train can be reduced.

[0059] Please refer to Figure 2 , in some examples, the geological disaster monitoring and forecasting system along the railway 3 further includes a waterproof box 25. The waterproof box 25 is arranged on the embedded part 21, the communicator 23 and the sensor 22 are arranged in the waterproof box 25, and the probe of the sensor 22 penetrates through the waterproof box 25. The waterproof box 25 can play a waterproof protection effect on the communicator 23 and the sensor 22 buried underground, which helps to ensure the normal operation of the disaster monitoring component 2.

[0060] In some examples, the waterproof box 25 can have an opening on one side, and at the same time, an opening for accommodating the detection probe 221 structure can be opened on the side wall of the waterproof box 25. The opening can be sealed. The waterproof box 25 can be buckled on the bottom plate 211 and can be fixedly connected to the bottom plate 211. The connection method can be bonding, welding or bolt connection.

[0061] In the description of this specification, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0062] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
