Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly.

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0030] In real-world applications, the layout of the dispatch room and the area of ​​personnel movement are not fixed. The movement positions and frequencies of on-duty personnel vary depending on the time of day and work mode. However, because existing brackets are difficult to adjust conveniently and over a wide range of angles, the camera's viewing angle cannot be flexibly optimized according to the actual layout and personnel movement. This makes it easy for the camera's viewing angle to be obstructed by frequently moving on-duty personnel during monitoring, resulting in key information areas not being effectively monitored and seriously affecting the completeness and accuracy of the monitoring.

[0031] On the other hand, existing support structures also have serious deficiencies in terms of locking stability after adjustment. When monitoring the large screen in the dispatching room, it is often necessary to precisely align the camera with specific display windows on the high-level screen, such as key information areas like the turnout status indicator area. The image information from these specific display windows is crucial for the back-end alarm linkage system to determine the operating status and issue timely warnings. However, due to the unstable locking of existing supports after adjustment, the camera angle is prone to shift after slight vibration or prolonged use, making it impossible to maintain precise alignment with specific display windows. This not only leads to inaccurate image information but also greatly affects image recognition accuracy, making it difficult for the back-end alarm linkage system to make reliable judgments based on accurate image information. Based on this, this utility model proposes a monitoring device for railway dispatching rooms.

[0032] The following is combined Figures 1-6 This invention describes a monitoring device for use in a railway dispatching room.

[0033] Reference 1 and Figure 4This utility model provides a monitoring device for a railway dispatching room, comprising: a telescopic member 10, a fixed base 20, a connecting member 30, and a monitoring component 40. The fixed base 20 is connected to the first end of the telescopic member 10 for detachable connection. The connecting member 30 is fixedly connected to the second end of the telescopic member 10, and is provided with a first mounting member 31 and a second mounting member 32. The monitoring component 40 includes a camera 41, a housing 42, a first fastener 43, and a second fastener 44. The camera 41 is fixedly connected to the housing 42; the housing 42 is provided with a fixing hole 4221 and an arc-shaped hole 4222, the arc-shaped hole 4222 being concentric with the fixing hole 4221. The housing 42 has a mounting cavity, and the connector 30 is disposed in the mounting cavity. The first mounting member 31 is correspondingly disposed with the fixing hole 4221, and the second mounting member 32 is correspondingly disposed with the arc-shaped hole 4222. The first fastener 43 passes through the fixing hole 4221 and is connected to the first mounting member 31, and the second fastener 44 passes through the arc-shaped hole 4222 and is connected to the second mounting member 32. The housing 42 can be rotated to adjust the position of the second mounting member 32 in the arc-shaped hole 4222, so as to adjust the angle of the camera 41.

[0034] The telescopic member 10 can extend and retract along its own extension direction to adjust its length. In one embodiment, the telescopic member 10 includes multiple telescopic rods, which are sequentially connected. Specifically, each of the adjacent ends of two adjacent telescopic rods is provided with multiple positioning holes (or one telescopic rod may have one positioning hole and the other telescopic rod may have multiple positioning holes). Fasteners pass through two positioning holes in sequence to connect the two telescopic rods. In actual use, the length of the telescopic member 10 can be adjusted by inserting fasteners into different positioning holes.

[0035] The first end of the telescopic component 10 is connected to the fixed base 20, and the second end of the telescopic component 10 is fixedly connected to the connecting component 30. The monitoring component 40 is rotatably connected to the connecting component 30. In actual use, the height of the monitoring component 40 can be adjusted by adjusting the length of the telescopic component 10. The first end of the telescopic component 10 can be welded to the fixed base 20, or it can be detachably connected to the fixed base 20 by threaded connection, screw connection, etc. The connection method between the second end of the telescopic component 10 and the connecting component 30 can also be welding, threaded connection, or screw connection, etc.

[0036] The mounting base 20 is used for detachable connection with the fixing component, which can be the ceiling of the control room, the side wall of the control room, or other stable structures. This allows the entire monitoring device to be fixed in place for easy monitoring by the monitoring component 40. The mounting base 20 can be connected to the fixing component using screws.

[0037] In one embodiment, the fixing base 20 includes a mounting plate 21 and at least two limiting plates 22. The two limiting plates 22 are respectively disposed on opposite sides of the mounting plate 21, and the two limiting plates 22 and the mounting plate 21 enclose a limiting space. The first end of the telescopic member 10 is disposed in the limiting space. In one embodiment, each limiting plate 22 is connected to the first end of the telescopic member 10 by fasteners to further fix the telescopic member 10 and improve stability. In one embodiment, there are four limiting plates 22, and the four limiting plates 22 and the mounting plate 21 enclose a limiting space, with the first end of the telescopic member 10 disposed within the limiting space. Further, each limiting plate 22 is connected to the first end of the telescopic member 10 by screws, which provides good stability. In one embodiment, the mounting plate 21 is provided with a groove, and the first end of the telescopic member 10 is disposed within the groove to prevent the telescopic member 10 from shifting during use.

[0038] In one embodiment, such as Figure 6 As shown, the mounting plate 21 is an "I"-shaped mounting plate 21. In one embodiment, two limiting plates 22 are disposed in the middle of the mounting plate 21 to improve stability. In another embodiment, the two limiting plates 22 and the mounting plate 21 are integrally formed, further enhancing the stability of the device.

[0039] The monitoring component 40 in this embodiment includes a camera 41, a housing 42, a first fastener 43, and a second fastener 44. The camera 41 can be a camera. The camera 41 is fixedly connected to the housing 42, such as by screws. In one embodiment, the housing 42 has multiple mounting holes spaced apart along the length of the housing 42. The camera 41 is mounted and fixed to the housing 42 through the mounting holes according to actual needs and can move together with the housing 42. The camera 41 can be disposed outside the housing 42. If the housing 42 has a mounting cavity, the camera 41 can also be disposed inside the mounting cavity, wherein the camera end 411 of the camera 41 extends out of the mounting cavity and is located outside the mounting cavity, used to acquire information collected in the railway dispatching room, including image recognition of track occupancy, turnout orientation, signal light color, etc.

[0040] refer to Figure 2 and Figure 3The housing 42 has a fixing hole 4221 and an arc-shaped hole 4222, with the arc-shaped hole 4222 concentric with the fixing hole 4221. The housing 42 has a mounting cavity into which the connector 30 is inserted. The connector 30 has a first mounting part 31 and a second mounting part 32. When the connector 30 is inserted into the mounting cavity, the first mounting part 31 corresponds to the fixing hole 4221, and a first fastener 43 can be connected to the first mounting part 31 through the fixing hole 4221. The first mounting part 31 can be a nut, and the first fastener 43 can be a bolt. The second mounting part 32 corresponds to the arc-shaped hole 4222, and a second fastener 44 can be connected to the second mounting part 32 through the arc-shaped hole 4222. The second mounting part 32 can be a nut, and the second fastener 44 can be a bolt, thereby connecting the housing 42 and the camera 41 to the connector 30. It should be noted that the connector 30 and the housing 42 can be fixedly or movably connected by adjusting the first fastener 43 and the second fastener 44. During the adjustment process, the connector 30 is movably connected to the housing 42. The housing 42 can be rotated manually or mechanically to adjust the position of the second mounting part 32 in the arc hole 4222, thereby adjusting the angle of the camera 41. After the camera 41 is adjusted to the target position, the connector 30 and the housing 42 are fixedly connected by adjusting the first fastener 43 and the second fastener 44.

[0041] In practical use, the mounting bracket 20 can be installed on the ceiling, avoiding the main passageway of the ceiling, and positioned above the side of the large screen to be monitored. By adjusting the length of the telescopic component 10, ensure that the initial position of the camera 41 is higher than the expected height of personnel in the dispatch room, and leave a certain adjustment margin. Based on this, by adjusting the connection between the first fastener 43 and the first mounting component 31, as well as the second fastener 44 and the second mounting component 32, the housing 42 and the connecting component 30 are made movable. Further, by viewing the real-time image to be monitored in the dispatch room through the camera 41, by controlling the housing 42 to rotate around the center of the fixing hole 4221, the second mounting component 32 moves within the arc groove, adjusting the angle of the camera 41. When the camera 41 can clearly monitor the real-time image in the dispatch room, by tightening the first fastener 43 and the first mounting component 31, the second fastener 44 and the second mounting component 32, the monitoring component 40 and the connecting component 30 can be locked, that is, the position of the monitoring component 40 is fixed, preventing the monitoring component 40 from moving. When the first mounting part 31 and the second mounting part 32 are nuts, and the first fastener 43 and the second mounting part 32 are bolts, the head of the bolt (or the nut) and the connecting part 30 generate a clamping force, thereby achieving rigid and stable locking and effectively resisting minor daily touches.

[0042] The monitoring device for railway dispatching rooms provided by this utility model has a monitoring component 40 connected to a fixed base 20 via a telescopic component 10. The monitoring component 40 can be flexibly adjusted according to different height requirements to monitor the monitoring screen or other specific areas in the dispatching room. By setting an arc-shaped hole 4222 on the housing 42, the angle of the camera 41 can be precisely adjusted to ensure comprehensive and clear monitoring of all key locations in the dispatching room. The fastening methods between the fixed base 20 and the telescopic component 10, the telescopic component 10 and the connecting component 30, and the connecting component 30 and the monitoring component 40 ensure the stability of the entire monitoring device during use, prevent movement during use, and ensure that the angle of the camera 41 is not affected by external forces, thus meeting the requirements of high precision and high stability for the dispatching room monitoring scenario.

[0043] This invention provides a precise and smooth motion trajectory by setting an arc-shaped hole 4222 on the housing 42. It features a simple and compact structure, low manufacturing cost, and high reliability. The first fastener 43 (bolt) connects to the first mounting part 31 (nut), and the second fastener 44 connects to the second mounting part 32 (nut). This provides strong locking force, simple operation requiring only an Allen wrench, and a secure and reliable lock without the risk of spontaneous angular deviation. The invention uses a telescopic component 10 for height adjustment and a connecting component 30 and monitoring component 40 for angle adjustment. These two components work together to significantly expand the effective viewing angle range and maximize the avoidance of personnel obstruction.

[0044] In some embodiments of this utility model, the arc angle formed by the arc-shaped hole 4222 is A, 0°≤A≤40°, that is, the adjustment range of the camera 41 relative to the telescopic member 10 is 0°-40°. In actual use, it can be adjusted according to the actual situation. The camera 41 can fully monitor the large screen in the dispatch room. In one embodiment, the camera 41 can be adjusted downwards relative to the telescopic member 10 by 15°, 30°, 40°, etc.

[0045] In some embodiments of this utility model, the housing 42 is made of stainless steel, mainly providing physical protection and aesthetic integration. The housing 42 has mounting cavities for mounting the connector 30 and the camera 41. In one embodiment, the mounting cavities include a first mounting cavity 421 and a second mounting cavity 422. The positions of the first mounting cavity 421 and the second mounting cavity 422 are not specifically limited, as long as they do not interfere with each other. In one embodiment, the first mounting cavity 421 and the second mounting cavity 422 are spaced apart along the height direction of the housing 42, i.e., the first mounting cavity 421 is closer to the connector 30, and the second mounting cavity 422 is farther away from the connector 30. The camera 41 is located within the first mounting cavity 421, protecting the camera 41. The camera 41 extends along the length direction of the housing 42 and has a camera end 411. The first mounting cavity 421 has a camera opening 4211, with the camera end 411 corresponding to the camera opening 4211, extending out of the first mounting cavity 421 to collect information from the large screen in the dispatch room. The connector 30 is located in the second mounting cavity 422, which has a clearance space 4223 to prevent interference with the telescopic member 10 during the rotation of the housing 42. Figure 2 and Figure 5 As shown, the clearance space 4223 is provided on the side wall of the second mounting cavity 422. In one embodiment, the first mounting cavity 421 and the second mounting cavity 422 are connected.

[0046] In some embodiments of this utility model, the opposite side walls of the housing 42 are provided with fixing holes 4221 and arc-shaped holes 4222. Correspondingly, the opposite sides of the connecting member 30 are also provided with first mounting members 31 and second mounting members 32. There are also two first fasteners 43 and two second fasteners 44, which can improve the stability of the structure and prevent the camera 41 from shifting during monitoring. It should be noted that during adjustment, both first fasteners 43 and both second fasteners 44 are movably connected to the connecting member 30. After adjustment, both first fasteners 43 and both second fasteners 44 are locked to the connecting member 30.

[0047] In some embodiments of this utility model, the monitoring device for a railway dispatching room further includes a controller and a speaker 50. The speaker 50 is disposed in the housing 42 and can be detachably connected to the housing 42 by screws. Both the speaker 50 and the camera 41 are communicatively connected to the controller. The controller receives image information acquired by the camera 41 and controls the operation of the speaker 50 based on the received image information. In one embodiment, if the controller determines that there is an anomaly in the image information, the controller controls the speaker 50 to play an alarm message to remind the staff in the dispatching room to handle the situation promptly, providing reliable front-end image acquisition support for track status monitoring based on image recognition and on-site turnout sound and light alarm linkage.

[0048] In some embodiments of this utility model, the monitoring device for railway dispatching room further includes a limiting member 60. The camera 41 is provided with a communication terminal 412, which is arranged opposite to the camera terminal 411. That is, the communication terminal 412 and the camera terminal 411 are respectively located at both ends of the extension direction of the camera 41. The extension direction of the camera 41 is consistent with the length direction of the housing 42. The limiting member 60 is provided on the inner wall surface of the housing 42, which can be the inner bottom surface of the housing 42 or the inner side wall surface of the housing 42. The communication terminal 412 is locked in the limiting member 60. The limiting member 60 is used to restrict the communication terminal 412 and prevent the communication terminal 412 from moving randomly or breaking accidentally.

[0049] In some embodiments of this utility model, the limiting member 60 is slidably connected to the inner wall surface of the housing 42, and the limiting member 60 can move along the length direction of the housing 42 to adjust the position of the limiting member 60 so that the position of the limiting member 60 matches that of the communication terminal 412, resulting in good stability. It should be noted that the length direction of the housing 42 is the same as the extension direction of the communication terminal 412. In one embodiment, the inner wall surface of the housing 42 is provided with a slide rail, which extends along the length direction of the housing 42, and the limiting member 60 has a sliding portion that is slidably connected to the slide rail.

[0050] like Figure 5 As shown, the limiting member 60 includes a fixing part 61 and a limiting part 62. The limiting part 62 is connected to the fixing part 61 and extends toward the communication end 412. In one embodiment, the fixing part 61 is slidably connected to the bottom surface of the first mounting cavity 421, and the limiting part 62 is vertically connected to the fixing part 61 and extends toward the communication end 412. Specifically, the bottom surface of the first mounting cavity 421 is provided with a sliding groove, which extends along the length of the housing 42. The fixing part 61 is provided with a through hole, which allows the fixing part 61 to be manually moved along the sliding groove to the target position (the position where the communication end 412 is to be limited). The fastener passes through the through hole and the sliding groove in sequence and is fixed to the bottom surface of the first mounting cavity 421 by the fastener fixing part 61.

[0051] In one embodiment, there are multiple sliding grooves, which are spaced apart along the width direction of the housing 42. Similarly, the fixing part 61 is provided with multiple through holes, the distance between two through holes being the same as the distance between two sliding grooves. These can be adjacent sliding grooves or spaced sliding grooves. After moving to the target position, the fastener can connect the fixing part 61 and the housing 42 through the corresponding through holes and sliding grooves, enhancing its stability. Furthermore, the limiting part 62 is provided with a limiting groove, which is located on the side near the communication end 412. The communication end 412 is engaged in the limiting groove. The limiting groove not only limits the movement but also provides support, preventing the communication end 412 from falling.

[0052] In some embodiments of this utility model, such as Figure 5 As shown, the communication terminal 412 has at least a first communication section and a second communication section. The first communication section and the second communication section form a stepped surface. The first communication section is locked in the limiting groove. The stepped surface abuts against the side of the limiting section 62 near the second communication section, restricting the movement of the communication section along the length direction of the housing 42 and restricting the camera 41.

[0053] The monitoring device for railway dispatching rooms provided by this utility model can flexibly adjust its height and angle according to actual needs, and has good stability, significantly improving the reliability and quality of front-end image acquisition. This provides solid technical support for back-end track safety monitoring based on large-screen image recognition and precise trackside crossing alarm linkage. Furthermore, it can be effectively applied to railway station level crossing early warning scenarios, providing strong protection for train operation safety and pedestrian safety.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
