Description

Technical Field

[0001] This application relates to the technical field of railway inspection, and particularly to a method for constructing a railway inspection area, a computer device, and a storage medium. Background Art

[0002] As an important national infrastructure, the main artery of the national economy, and a popular means of transportation, railways play a backbone role in China's comprehensive transportation system. Their safe and stable operation is not only related to the sustainable and healthy development of the national economy but also closely related to the life and property safety of the general public. Therefore, railway inspection work is a key link in ensuring the safe operation of railways. Traditional railway inspection methods mainly rely on manual inspections. Inspection personnel conduct on-site inspections along railway lines and discover potential safety hazards such as equipment failures and line damages through visual inspection, listening, etc. However, this method has many drawbacks. On the one hand, manual inspection is inefficient. Railway lines are long and widely distributed, and inspection personnel need to spend a large amount of time and energy, making it difficult to conduct comprehensive and timely inspections. On the other hand, manual inspection is greatly affected by subjective factors. The experience, responsibility, and working status of inspection personnel will all affect the inspection quality, and problems such as missed inspections and misjudgments are likely to occur.

[0003] With the continuous development of technology, some automated inspection devices such as track inspection vehicles and drones have gradually been applied to the field of railway inspection. These devices can improve inspection efficiency and accuracy to a certain extent, but they also have certain limitations. For example, track inspection vehicles usually can only run on specific tracks and it is difficult to conduct comprehensive inspections on some complex line environments and equipment details; although drone inspections are flexible, they are restricted by factors such as weather and airspace control during flight, and the image data obtained by them needs to be analyzed manually later, and the efficiency still needs to be improved.

[0004] In railway inspection work, monitoring devices such as optical fibers, cameras, or radars are introduced to inspect railways, which greatly improves the efficiency of railway inspection. However, the data monitored by these monitoring devices cannot be well combined with the actual scene, making it inconvenient for staff to conduct auxiliary inspections and detect alarm information. Summary of the Invention

[0005] The main technical problem to be solved by this application is to provide a method for constructing a railway inspection area, which solves the problem that the data monitored by monitoring devices cannot be well combined with the actual scene, making it inconvenient for staff to conduct auxiliary inspections and detect alarm information.

[0006] To solve the above technical problem, a technical solution adopted by this application is to provide a method for constructing a railway inspection area, including the steps:

[0007] A preset area generation module, where there are multiple area shapes corresponding to the area generation module. After triggering one of the area shapes, at least two position points are preset on the real-scene image. Based on the position points, the selected area shape is automatically generated, and the area shape encloses to form a monitoring defense area;

[0008] Associate the monitoring devices in the actual scene with the monitoring defense area in the real-scene image to form a device association module. Trigger the device association module, and display the monitoring data and / or alarm data of the monitoring devices corresponding to the device association module outside the real-scene image.

[0009] In some embodiments, the area shapes corresponding to the area generation module are straight lines or curves. When this area generation module is selected, after determining one position point, when determining the next position point; a straight line or curve is automatically generated to connect the two position points together; when the last position point is connected to the first position point, it encloses to form a monitoring defense area.

[0010] In some embodiments, in the real-scene image, divide multiple monitoring defense areas, and preset an identification module to uniquely identify the monitoring defense areas to distinguish multiple monitoring defense areas.

[0011] In some embodiments, according to the scale relationship between the real-scene image and the actual scene, the actual monitoring range of the monitoring device is correspondingly mapped to the real-scene image according to the scale relationship. In the monitoring defense area of the real-scene image, preset the pixel position of the monitoring device on the real-scene image so that the monitoring range of the monitoring device can completely cover the monitoring defense area. During the actual installation of the monitoring device, through a handheld terminal, obtain the longitude and latitude coordinates of the monitoring device at the actual position of the monitoring device, and map the longitude and latitude coordinates to the pixel position in the real-scene image to correct the pixel position of the monitoring device on the real-scene image.

[0012] In some embodiments, preset a device association module, where the device association module corresponds to the pixel position of the monitoring device on the real-scene image, and the device association module is connected to the monitoring data of the monitoring device.

[0013] In some embodiments, preset an alarm module, where the alarm module is associated with the device association module. When the monitoring device associated with the device association module detects an abnormality, trigger the alarm module, and the alarm module marks the corresponding device association module.

[0014] In some embodiments, the alarm module generates alarm data according to the abnormal conditions detected by the monitoring device and displays the alarm data outside the real-scene image; the staff determines whether to give an alarm again according to the alarm data.

[0015] In some embodiments, the rail surface of the railway is divided into a first monitoring defense area, and monitoring cameras and / or monitoring radars are arranged on the long sides of the first monitoring defense area to monitor whether there are foreign objects on the railway rail surface;

[0016] The slope between the railway rail surface and the perimeter fence is divided into a second monitoring defense area, and the shape of the second monitoring defense area is divided according to the shape of the slope; in the second monitoring defense area, monitoring optical fibers are laid to monitor whether the slope deforms;

[0017] The area outside the perimeter fence is divided into a third monitoring defense area, and the shape of the third monitoring defense area is divided in combination with the shape of the terrain outside the perimeter fence; in the third monitoring defense area, monitoring optical fibers are laid to monitor whether the terrain changes, and / or monitoring cameras and / or monitoring radars are arranged at the third monitoring defense area to monitor whether there are foreign objects.

[0018] The present application also provides a computer device, including a memory, a processor, and a computer program stored on the memory and executable on the processor.

Thus, the monitoring data and / or alarm data of the monitoring device can be conveniently observed. Through the monitoring data, the staff can perform auxiliary inspections, conduct subsequent analysis and problem tracing according to the monitoring data, so as to discover potential problems in the monitoring defense area in advance. Through the alarm data, the abnormal data detected by the monitoring device is reconfirmed to determine whether to give an alarm, thereby ensuring the safety of the railway monitoring defense area.

[0029] Figure 1 Shows an embodiment of the construction method of the railway inspection area of the present application, including:

[0030] Step S1: A preset area generation module, where the area generation module corresponds to multiple area shapes. After triggering one of the area shapes, at least two position points are preset on the real-scene image, and based on the position points, the selected area shape is automatically generated, and the area shape encloses to form a monitored defense area 1;

[0031] Step S2: Associate the monitoring devices in the actual scene with the monitored defense area 1 in the real-scene image to form a device association module 2. After triggering the device association module 2, the monitoring data and / or alarm data of the monitoring devices corresponding to the device association module 2 are displayed outside the real-scene image.

[0032] In this application, when using a monitoring device to conduct inspections on Monitoring Area 1, preset position points on the real-scene image and divide Monitoring Area 1. Associate the monitoring devices in the actual scene with Monitoring Area 1. When a monitoring device is triggered, display the monitoring data and / or alarm data of the monitoring device outside the real-scene image. In this way, it is possible to conveniently observe the monitoring data and / or alarm data of the monitoring device. Through the monitoring data, the staff can conduct assisted inspections, perform subsequent analysis and problem tracing based on the monitoring data, so as to discover potential problems in Monitoring Area 1 in advance. Through the alarm data, reconfirm the abnormal data detected by the monitoring device to determine whether to give an alarm, thereby ensuring the safety of Railway Monitoring Area 1.

[0033] The surrounding of the railway can be photographed by a drone, and the obtained image is used as the real-scene image. The image taken by a satellite can also be used as the real-scene image. The real-scene image can also be the image displayed on a GIS map. This can improve the convenience of obtaining the real-scene image. Then, on the real-scene image, divide multiple levels of Monitoring Area 1. In this way, it can be ensured that the defined Monitoring Area 1 matches the actual scene around the railway, and the divided Monitoring Area 1 can intuitively and accurately reflect the monitoring data in the actual scene around the railway.

[0034] After obtaining the real-scene image, determine the position points according to the shape of the terrain on the real-scene image.

[0035] In some embodiments, as Figure 2 and Figure 3 shown, when the shape of the terrain on the real-scene image is a regular square shape, the center point of the terrain can be used as the first position point, and a vertex of the terrain can be used as the second position point to form a square Monitoring Area 1 covering the square shape. It is also possible to use a vertex of the terrain as the first position point and the other opposite vertex as the second position point to form a square Monitoring Area 1 covering the square shape. It is also possible to use the four vertices of the terrain as the first position point, the second position point, the third position point, and the fourth position point, and connect the first position point, the second position point, the third position point, the fourth position point, and the first position point in sequence to enclose and form a square Monitoring Area 1 covering the square shape.

[0036] When the shape of the terrain on the real-scene image is a regular circle, the center of the circle of the terrain can be used as the first position point, and the position of the radius vertex of the terrain can be used as the second position point to form a circular Monitoring Area 1 covering the circular shape.

[0037] When the shape of the terrain on the real-scene image is an irregular shape, at the inflection points of the irregular shape, preset a position point, and connect these position points with straight lines or curves to enclose and form a Monitoring Area 1 covering the terrain.

[0038] In some embodiments, there is a preset area generation module. The area generation module corresponds to a certain area shape. After selecting the area generation module, based on the position points, the area shape corresponding to the area generation module is automatically generated.

[0039] For example, when the area shape corresponding to the area generation module is a square, after selecting this area generation module and determining the first position point, when determining the second position point, a square monitoring defense area 1 is automatically generated.

[0040] When the area shape corresponding to the area generation module is a circle, after selecting this area generation module and determining the first position point, when determining the second position point, a circular monitoring defense area 1 is automatically generated.

[0041] When the area shape corresponding to the area generation module is a straight line or a curve, after selecting this area generation module and determining one position point, when determining the next position point, a straight line is automatically generated to connect the two position points. When the last position point is connected to the first position point, a monitoring defense area 1 is enclosed.

[0042] In some embodiments, as Figure 3 shown, when dividing the monitoring defense area 1 on the real-scene image of the GIS map, the longitude and latitude coordinates on the GIS map can be extracted and used as the position points to generate the monitoring defense area 1.

[0043] Through the above method, the division of the monitoring defense area 1 in the real-scene image can be completed, enabling the divided monitoring defense area 1 to be fully adapted to the terrain in the real-scene image, laying a foundation for accurately displaying the alarm position.

[0044] In some embodiments, in the real-scene image, multiple monitoring defense areas 1 can be divided. When there are multiple monitoring defense areas 1, a preset identification module is used to uniquely identify the monitoring defense areas 1 to distinguish between multiple monitoring defense areas 1. As Figure 4 shown, the identification module 3 includes a name identification unit, a number identification unit, a color identification unit, and / or a position identification unit.

[0045] In the name identification unit, the monitoring defense area 1 can be named, and each monitoring defense area 1 corresponds to a different name to distinguish it from other monitoring defense areas 1.

[0046] In the number identification unit, the monitoring defense areas 1 can be numbered in sequence according to the distance from the railway rail surface or the order of dividing the monitoring defense areas 1 to distinguish them from other monitoring defense areas 1.

[0047] In the color identification unit, the color corresponding to Monitoring Area 1 can be preset. According to the different monitoring types of Monitoring Area 1, the corresponding color is selected to distinguish it from other Monitoring Areas 1. For example, the monitoring types of Monitoring Area 1 include rail surface, fence net, slope, passive net, rail surface at tunnel entrance, external environment, height limit gantry, overpass railway bridge, and water culvert, etc. Each monitoring type can correspond to a color. In the color identification unit, the monitoring type and its corresponding color can be pre-saved. In the color identification unit, the monitoring type and its color corresponding to this Monitoring Area 1 can be directly selected to distinguish it from other Monitoring Areas 1.

[0048] In the position identification unit, the location of Monitoring Area 1 can be preset, and the corresponding location of this Monitoring Area 1 is selected to accurately locate Monitoring Area 1.

[0049] Through the above method, the identification of multiple Monitoring Areas 1 can be completed. Thus, Monitoring Areas 1 can be intuitively and accurately distinguished, and the monitoring type, location, etc. of Monitoring Area 1 can be quickly judged, laying a foundation for intuitively displaying the alarm location.

[0050] In some embodiments, Monitoring Area 1 can be divided first, and then monitoring devices can be installed according to Monitoring Area 1 to determine the positioning coordinates of the monitoring devices. It is also possible to install monitoring devices around the railway first, and then determine Monitoring Area 1 according to the positioning coordinates of the monitoring devices.

[0051] In some embodiments, when Monitoring Area 1 is divided first and then the positioning coordinates of the monitoring devices are determined, according to the proportional relationship between the real scene image and the actual scene, the actual monitoring range of the monitoring devices is correspondingly mapped to the real scene image according to the proportional relationship. Within Monitoring Area 1 of the real scene image, the pixel position of the monitoring device on the real scene image is preset so that the monitoring range of the monitoring device can completely cover Monitoring Area 1. During the actual installation of the monitoring device, the pixel position of the monitoring device on the real scene image is then corresponded to the installation position in the actual scene, and the monitoring device is installed in the actual scene.

[0052] When the monitoring device is installed in the actual scene, through a handheld terminal, the longitude and latitude coordinates of the monitoring device are obtained at the actual position of the monitoring device, and the longitude and latitude coordinates are corresponded to the pixel position in the real scene image to correct the pixel position, so that the actual installation position of the monitoring device in the actual scene is accurately corresponded to the pixel position of the monitoring device in the real scene image. Thus, the accurate position of the monitoring device on the real scene image can be accurately monitored, and thus it can be accurately shown which monitoring device has an abnormality in the actual scene for alarm.

[0053] In some embodiments, the monitoring device is first installed in the actual scenario, and then the monitoring area 1 is determined on the real-scene image. When the monitoring device is installed in the actual scenario, the longitude and latitude coordinates of the monitoring device are obtained at the actual position of the monitoring device through a handheld terminal, and the longitude and latitude coordinates and the monitoring range of the monitoring device are mapped to the real-scene image to determine the pixel position of the monitoring device in the real-scene image. By using the above method for dividing the monitoring area 1 to standardize the area covered by the monitoring range, the monitoring area 1 can be formed. The purpose of standardization is to accurately determine the monitoring area 1. For example, when a monitoring camera or a monitoring radar is used as the monitoring device to monitor the rail surface of a railway, the monitoring range of the monitoring camera or the monitoring radar will cover the slope of the rail surface. If the method for dividing the monitoring area 1 is not used for standardization, the monitoring area 1 will be unclear. By using the method for dividing the monitoring area 1, the monitoring area 1 of the monitoring camera or the monitoring radar on the real-scene image can be restricted to the rail surface, so that the abnormal conditions on the rail surface can be accurately displayed.

[0054] In some embodiments, the above-mentioned handheld terminal can be a general mobile sub-platform or a dedicated mobile sub-platform, including a GPS positioning system or a Beidou positioning system. In specific implementation, the handheld terminal can be a desktop computer, a portable computer, a network server, a personal digital assistant (PDA), a mobile phone, a smart bracelet, a smart watch, a tablet computer, a wireless terminal device, a communication device or an embedded device.

[0055] In some embodiments, after the monitoring device is actually installed, the monitoring data of the monitoring device is associated with the real-scene image. As Figure 5 shown, a preset device association module 2 is provided, and the device association module 2 corresponds to the pixel position of the monitoring device in the real-scene image. The device association module 2 includes a defense area unit and an associated device unit. Triggering the defense area unit can display the monitoring devices in this defense area. In the associated device unit, information such as the longitude and latitude coordinates of the device can be displayed. And the monitoring device is added to the corresponding defense area unit. The device association module 2 is connected to the monitoring data of the monitoring device. After triggering the device association module 2, the monitoring data of the monitoring device corresponding to the device association module 2 is displayed on the outside of the real-scene image. The monitoring data can include information such as the stress change curve of the monitoring optical fiber, video images, and monitoring positions. Through the device association module 2, the monitoring data of the corresponding monitoring device can be selectively displayed, so that the abnormal conditions monitored by the monitoring device can be accurately located.

[0056] In some embodiments, as Figure 2As shown, there is a preset alarm module 4. The alarm module 4 is associated with the device association module 2. When the monitoring device associated with the device association module 2 detects an abnormality, the alarm module 4 is triggered. The alarm module 4 marks the corresponding device association module 2 and displays the abnormal data detected by the monitoring device on the outside of the real - scene image.

[0057] When the alarm module 4 marks the device association module 2, it can highlight the device association module 2 or mark it in red, so that the staff can visually observe which monitoring device detected the abnormality.

[0058] In some embodiments, the alarm module 4 generates alarm data according to the abnormal conditions detected by the monitoring device and displays the alarm data on the outside of the real - scene image. The staff can determine whether to give an alarm according to the alarm data. The alarm data includes alarm information, alarm pictures, alarm playback, and / or alarm handling, etc. In the alarm information, the alarm location, the name of the alarm railway line, the alarm level, the alarm time, etc. can be displayed. In the alarm pictures, the data change process can be displayed. In the alarm playback, the alarm time and the time period of a few minutes before and after it can be displayed to show the source of the abnormality. In the alarm handling, the handling personnel and handling measures can be set.

[0059] The monitoring device can collect various data of the railway line in real - time, such as temperature, vibration, displacement, etc., and transmit these data to the monitoring center. These data are visually displayed on the real - scene image, enabling the inspection personnel to quickly understand the operating status of the railway line and equipment. Once the monitoring data shows an abnormality, an alarm message can be sent in a timely manner to remind the inspection personnel to take corresponding measures, thus realizing the early detection and early treatment of railway safety hazards and effectively avoiding the occurrence of accidents.

[0060] In practical applications, as Figure 2 and Figure 5 shown, different monitoring devices can be set according to different monitoring types. The rail surface of the railway can be divided into the first monitoring defense zone 10. The shape of the first monitoring defense zone 10 is rectangular. Monitoring devices are set on the long sides of the first monitoring defense zone 10. The monitoring devices for the first monitoring defense zone 10 can be monitoring cameras and / or monitoring radars, and whether there are foreign objects on the railway rail surface is monitored through the monitoring cameras and / or monitoring radars.

[0061] The length of the long side of the first monitoring defense zone 10 is S, the maximum length that the monitoring device can cover is L, and the distance s between adjacent monitoring devices is less than the maximum length and greater than half of the maximum length, which is expressed as:

[0062] L / 2 ≤ s ≤ L

[0063] This can not only ensure that the monitoring devices can fully cover the monitored defense areas, but also reduce the waste of resources of the monitoring devices.

[0064] The number of monitoring devices is greater than or equal to the length of the monitored defense area divided by the maximum length that the monitoring device can cover.

[0065] The number a of monitoring devices is expressed as:

[0066] S / L ≤ a

[0067] The slope between the railway track surface and the perimeter fence is divided into the second monitored defense area 20, and the shape of the second monitored defense area 20 is divided according to the shape of the slope. In the second monitored defense area 20, monitoring optical fibers can be laid to monitor whether the slope deforms. The monitoring optical fibers are laid horizontally or meanderingly on the slope. The monitoring optical fibers include stress optical fibers and acoustic optical fibers, etc. The monitoring optical fibers include multiple fiber composite sensors and a demodulator. One demodulator can receive the signals of multiple fiber composite sensors. The fiber composite sensors are located on the slope, and multiple fiber composite sensors can be arranged on each slope to comprehensively monitor the slope.

[0068] The area outside the perimeter fence is divided into the third monitored defense area 30, and the shape of the third monitored defense area 30 is divided in combination with the shape of the terrain outside the perimeter fence. In the third monitored defense area 30, monitoring optical fibers can be laid to monitor whether its terrain changes, or monitoring cameras and / or monitoring radars can be set at the third monitored defense area 30 to monitor whether there are foreign objects such as falling rocks. The monitoring optical fibers, monitoring cameras and / or monitoring radars can be set according to the above setting method.

[0069] Through the above method, hierarchical alarm can be realized outside the railway. The closer to the track surface, the higher the alarm level, and the higher the attention to the monitored defense area in the real scene image is also required.

[0070] When the monitored defense area is inspected by the monitoring devices, preset position points are set on the real scene image and the monitored defense area is divided. The monitoring devices in the actual scene are associated with the monitored defense area. When a monitoring device is triggered, the monitoring data and / or alarm data of the monitoring device are displayed outside the real scene image. In this way, the monitoring data and / or alarm data of the monitoring device can be conveniently observed. Through the monitoring data, the staff can conduct auxiliary inspections, and conduct subsequent analysis and problem tracing according to the monitoring data, so as to discover potential problems in the monitored defense area in advance. Through the alarm data, the abnormal data monitored by the monitoring device is reconfirmed to confirm whether to give an alarm, so as to ensure the safety of the railway monitored defense area.

[0071] The above are only embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
