[0025] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a railway foreign object detection device 10, including a visible light module 11, a lidar module 12, an infrared thermal imaging module 13, and a control module (not shown in the figure). The visible light module 11 is used to acquire visible light images of foreign objects within the detection area; the lidar module 12 is used to scan the foreign objects within the detection area using a laser; and the infrared thermal imaging module 13 is used to acquire infrared thermal images of the foreign objects within the detection area. The control module is communicatively connected to the visible light module 11, the lidar module 12, and the infrared thermal imaging module 13, and is used to receive the acquired data from these modules.
[0026] It should be noted that the detection area refers to the actual area that the railway foreign object detection device 10 can detect. The specific location and range of the detection area can be set according to the needs of actual use. For example, the detection area can be set to the track and railway station where the train is to travel.
[0027] The visible light module 11 can acquire visible light images of the detection area in real time and send the acquired data to the control module. The lidar module 12 can emit a laser beam into the detection area, receive the reflected signal, and compare the reflected signal with the emitted signal to obtain relevant information about foreign objects in the detection area, such as distance, position, area, and height.
[0028] Furthermore, the infrared thermal imaging module 13 can acquire infrared thermal images of the detection area in real time. When a foreign object is detected in the detection area, the location and type of the foreign object can be determined based on the infrared thermal image.
[0029] The control module can be shared with the visible light module 11, the lidar module 12, and the infrared thermal imaging module 13, or it can be externally mounted. The control module can receive data collected from the visible light module 11, the lidar module 12, and the infrared thermal imaging module 13, and summarize the various collected data to better reflect the status of foreign objects in the detection area.
[0030] The above structure integrates a visible light module 11, a lidar module 12, and an infrared thermal imaging module 13. Through the cooperation of these three components, it is possible to more accurately detect intrusive foreign objects at night or in low-light environments, and to achieve detection over a longer range. This improves the detection efficiency and accuracy of the railway foreign object detection device 10, making railway traffic safer.
[0031] In some embodiments, the railway foreign object detection device 10 further includes a supplementary lighting module 14, which is connected to the visible light module 11 and is used to supplement the visible light module 11.
[0032] Specifically, the supplementary lighting module 14 can supplement the visible light module 11 according to the actual light conditions in the detection area, so that the visible light module 11 can perform detection more clearly at night or in low light environments, effectively improving the performance and quality of the visible light module 11 in capturing and detecting.
[0033] In some embodiments, the railway foreign object detection device 10 further includes an alarm module 15, which is communicatively connected to the control module and configured to trigger an alarm based on the collected data.
[0034] Specifically, the alarm module 15 can automatically or manually trigger an alarm based on the content of each collected data, providing timely reminders when foreign objects intrude, thereby improving driving safety.
[0035] In some embodiments, the railway foreign object detection device 10 further includes a detachably connected upper housing 16 and a lower housing 17, the upper housing 16 and the lower housing 17 together forming a receiving cavity, which is used to accommodate the visible light module 11, the lidar module 12 and the infrared thermal imaging module 13.
[0036] Specifically, the upper housing 16 and the lower housing 17 can be detachably connected by means of bolts, snap-fit connections, etc. The detachable connection makes it easier to assemble and disassemble the upper housing 16 and the lower housing 17, and makes it easier to operate the visible light module 11, the lidar module 12, and the infrared thermal imaging module 13 inside the cavity.
[0037] In addition, the control module can be located inside the cavity or externally.
[0038] Based on the same concept as the railway foreign object detection device 10 described above, this application also provides a railway foreign object detection system 100, including a network device 20 and at least one railway foreign object detection device 10 as described above. The network device 20 includes at least one detection access point 21, each detection access point 21 is configured one-to-one with each railway foreign object detection device 10, and is communicatively connected to the control module in the corresponding railway foreign object detection device 10. The detection access point 21 is used to receive and analyze the data collected by the corresponding control module.
[0039] Specifically, the railway foreign object detection device 10 can be used as a front-end acquisition device, and can be adjusted according to the number of detection areas to be detected, so that at least one railway foreign object detection device 10 corresponds to one detection area.
[0040] The network device 20 can be a local wired LAN or an Internet service provider network. The network device 20 includes at least one detection access point 21, and each detection access point 21 corresponds to a railway foreign object detection device 10. Thus, when the railway foreign object detection device 10 detects a foreign object, it can quickly transmit the collected data to the corresponding detection access point 21. The detection access point 21 can encode and process the received data for transmission and storage.
[0041] Therefore, by setting up the detection access point 21, the storage capacity and analysis and calculation capabilities of the collected data can be improved.
[0042] In some embodiments, the network device 20 further includes at least one area node 22, each area node 22 being connected to at least two detection access points 21. Each area node 22 is configured to controllably classify the data collected by the corresponding detection access point 21 into normal intrusion signals and abnormal intrusion signals.
[0043] Each detection access point 21 can aggregate the collected data to the corresponding area node 22. The area node 22 can process, store, and analyze the collected data from the multiple detection access points 21 connected to it, and can also manage the foreign object intrusion within the range of each detection access point 21.
[0044] Furthermore, operators can manually identify the intrusion situation of each regional node 22, divide the collected data into normal intrusion signals and abnormal intrusion signals, cancel normal intrusion signals, and confirm abnormal intrusion signals.
[0045] It should be noted that a certain area node 22 includes multiple detection access points 21, each corresponding to a track or a railway station. At present, only one or a few tracks are experiencing vehicle entry or exit. Therefore, foreign object intrusion at a track or railway station with vehicle traffic is considered an abnormal intrusion signal, while foreign object intrusion at a track or railway station without vehicle traffic is considered a normal intrusion signal. It is only necessary to provide a notification or alarm for abnormal intrusion signals.
[0046] In some embodiments, the railway foreign object detection device 10 further includes an alarm module 15, which is used to receive abnormal intrusion signals and issue an alarm.
[0047] Specifically, each regional node 22 can send the identified abnormal intrusion signals to the alarm module 15, enabling the alarm module 15 to issue an alarm for the abnormal intrusion signals.
[0048] In some embodiments, the network device 20 further includes a core node 23, which is connected to all area nodes 22 and is used to store and manage all collected data from the area nodes 22.
[0049] Specifically, a core node 23 can be set as one and connected to all regional nodes 22. That is, the scheduling center of the core node 23 can summarize and manage the foreign object intrusion situation of all regional nodes 22, and can store historical data to facilitate querying of historical data and better obtain information on foreign object intrusion.
[0050] By detecting access point 21, regional node 22 and core node 23, the railway foreign object detection system 100 can form a three-level structure, which facilitates the transmission, storage, analysis and management of foreign object intrusion events in the entire range of track lines, railway stations and other important areas under the jurisdiction of the dispatch center of core node 23.
[0051] In some embodiments, the railway foreign object detection system 100 further includes an indoor detection terminal 30 and an indoor display screen 40 connected to each other. The indoor detection terminal 30 is connected to the core node 23 and is used to query all the collected data of the core node 23. The indoor display screen 40 is used to display the query results of the indoor detection terminal 30.
[0052] Specifically, the indoor detection terminal 30 can query all foreign object intrusion situations within the dispatch center range of the core node 23, and can display the query results on the indoor display screen 40 for easy reading.
[0053] In some embodiments, the railway foreign object detection system 100 further includes a mobile user terminal 50 connected to the core node 23. The mobile user terminal 50 is used to query the time of foreign object intrusion and to receive foreign object intrusion alerts sent by the core node 23.
[0054] Specifically, the mobile user terminal 50 can quickly query the time of the foreign object intrusion and can promptly receive the foreign object intrusion alert sent by the scheduling center of the core node 23, so as to make a timely judgment.
[0055] According to one or more embodiments, when this application is used, a railway foreign object detection device 10 is first set up in each detection area that needs to be detected. Each railway foreign object detection device 10 corresponds to a detection access point 21. The detection access point 21 can synchronize the video, radar and infrared thermal imaging data collected by the corresponding railway foreign object detection device 10 in real time.
[0056] Furthermore, each detection access point 21 encodes and processes the collected data for transmission and storage. The area node 22 receives the collected data from its corresponding detection access points 21 and processes, stores, and analyzes it. Simultaneously, operators manually screen the collected data from the area node 22, disabling normal intrusion signals and confirming abnormal intrusion signals.
[0057] The area node 22 sends the abnormal intrusion signal to the alarm module 15 in the corresponding railway foreign object detection device 10, and the alarm module 15 will trigger an alarm.
[0058] The core node 23 receives the collected data from each regional node 22, integrates and manages it, and stores historical foreign object intrusion information for subsequent querying.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
