Description

Technical Field

[0001] This utility model relates to the field of railway safety, and in particular to a monitoring device for speed limit signs on railway operating lines. Background Technology

[0002] During the construction and maintenance of conventional-speed railways, to ensure the safety of train operation and construction personnel, in accordance with the "Technical Management Regulations for Conventional-Speed ​​Railways" and the "Railway Safety Rules," speed limits must be implemented for trains in areas where construction or maintenance work affects the stability of the line after opening, and a step-by-step speed increase measure must be adopted. Simultaneously, the train speed is automatically adjusted by data from the LKJ system, but the train driver still needs to visually confirm the starting mileage and speed requirements of the speed-limited sections to ensure train operation safety.

[0003] During the closure of operating railway lines for construction, to prevent trains or other self-propelled equipment from entering the work area, the construction unit must install protective signal signs along the railway line to remind drivers to limit speed or stop. Commonly used signal signs include mobile stop signs, mobile deceleration signs, and work markers. The construction unit installs speed limit signs at designated locations (calculated based on the corresponding railway mileage) according to the railway's monthly construction plan. The speed limit signs must be at least 2.44 meters from the center of the adjacent operating line and buried a certain depth below the top surface of the roadbed to maintain overall stability. The numbers on the speed limit signs must face the direction of oncoming trains. After installation, protective personnel replace the round signs with different speed numbers according to the required speed limit time, controlling the placement and removal of the speed limit signs according to the work schedule. Between replacements, the speed limit signs are usually unattended. If a speed limit sign tilts during this unattended period and the staff is unaware of the situation, it can easily lead to dangerous situations such as traffic accidents. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as speed limit signs being unattended, which can easily lead to dangerous situations like traffic accidents if the speed limit sign falls over and staff cannot detect the situation. This invention provides a monitoring device for speed limit signs on railway operating lines.

[0005] In a first aspect, this utility model provides a monitoring device for speed limit signs on railway operating lines, including a pole, one end of which is connected to a road shoulder and the other end of which is connected to a speed limit sign. A detector structure is provided at intervals on one side of the pole. The detector structure includes a reed switch. A permanent magnet structure is provided on the side of the pole facing the reed switch. One side of the permanent magnet structure is connected to the pole and the other side is spaced apart from the reed switch. The reed switch is configured to disconnect when the distance between it and the permanent magnet structure reaches a certain threshold. The pole is equipped with a monitoring chip, which is electrically connected to the reed switch. The monitoring chip is used to collect the opening and closing signals of the reed switch. The monitoring chip is equipped with a communication module, which is connected to the monitoring chip. The communication module is used to transmit the opening and closing signal of the reed switch to an external terminal.

[0006] This utility model provides a monitoring device for speed limit signs on railway operating lines. A pole with a speed limit sign is inserted into the shoulder of the railway, equipped with a reed switch and a permanent magnet structure that works in conjunction with the reed switch. When the speed limit sign is tilted, toppled, or moved by external force, causing the distance to exceed a set threshold, the reed switch immediately disconnects. The pole also has a monitoring chip electrically connected to the reed switch. This monitoring chip collects the opening and closing signals of the reed switch. When the reed switch disconnects, the monitoring chip receives the signal and sends it to an external terminal via a communication module. This allows for timely warnings to protection personnel or management terminals when the speed limit sign tilts, shifts, or becomes unstable, enabling protection personnel to quickly take measures to prevent the speed limit sign from encroaching on the operating line clearance and affecting train operation safety.

[0007] Preferably, the detector structure further includes a detector mounting rod, which is arranged parallel to the upright.

[0008] By setting the detector mounting rod parallel to the upright, the relative positions of the reed switch and permanent magnet structure can be determined when they are fixed.

[0009] Preferably, both the upright pole and the detector mounting pole are equipped with anti-tipping devices at the ends facing the road shoulder.

[0010] Improve the connection stability of the pole and detector mounting pole when they are connected to the roadbed.

[0011] Preferably, the reed switch is configured to disconnect when the distance between the reed switch and the permanent magnet structure is greater than 1.5 mm.

[0012] Preferably, the anti-tipping device body has a fork-shaped structure.

[0013] By designing the anti-tipping device as a fork-shaped structure, it can form multiple points of support when the pole is inserted into the shoulder, increasing the contact area and friction with the foundation, and effectively improving the stability of the speed limit sign.

[0014] Preferably, the outer surface of the pole is provided with an anti-corrosion layer.

[0015] By applying an anti-corrosion layer to the outer surface of the pole, it is possible to effectively resist the corrosive effects of rainwater, moisture, and other harsh environments on the pole, thus extending the service life of the device.

[0016] Preferably, the speed limit sign has a reflective layer on its surface.

[0017] By setting a reflective layer on the surface of the speed limit sign, the train's headlights can be reflected at night or in low visibility environments such as rain and fog, enabling train drivers to identify speed limit information in a timely and clear manner, improving visual confirmation, and thus further ensuring the safety and reliability of train operation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a monitoring device for speed limit signs on railway operating lines. A pole with a speed limit sign is inserted into the shoulder of the railway, equipped with a reed switch and a permanent magnet structure that works in conjunction with the reed switch. When the speed limit sign is tilted, toppled, or moved by external force, causing the distance to exceed a set threshold, the reed switch immediately disconnects. The pole also has a monitoring chip electrically connected to the reed switch. This monitoring chip collects the opening and closing signals of the reed switch. When the reed switch disconnects, the monitoring chip receives the signal and sends it to an external terminal via a communication module. This allows for timely warnings to protection personnel or management terminals when the speed limit sign tilts, shifts, or becomes unstable, enabling protection personnel to quickly take measures to prevent the speed limit sign from encroaching on the operating line clearance and affecting train operation safety.

[0021] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0022] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0024] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0025] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0026] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0027] Example 1 like Figure 1 and Figure 2 The speed limit sign monitoring device for railway operating lines shown includes a pole 1 inserted into the shoulder, one end of which is connected to the shoulder and the other end to a speed limit sign 2. The speed limit sign 2 monitoring device also includes a detector structure 3, which includes a detector mounting rod 32. A reed switch 31 is provided on the detector mounting rod 32. A permanent magnet structure 4 is provided on the side of the pole 1 facing the reed switch 31. The reed switch 31 is configured to disconnect when the gap between itself and the permanent magnet structure 4 reaches a preset threshold. A monitoring chip 5 is provided on the pole and is electrically connected to the reed switch 31. The monitoring chip 5 is used to collect the opening and closing signals of the reed switch 31. The monitoring chip 5 is equipped with a communication module 7 and is connected to the monitoring chip 5. The communication module 7 is used to transmit the opening and closing signals of the reed switch 31 to an external terminal. Furthermore, the preset threshold is 1.5mm.

[0028] Specifically, when the speed limit sign 2 tilts over (since the detector mounting rod 32 and the upright 1 are set up independently and parallel to each other, the tilting of the upright 1 will not affect the position of the detector mounting rod 32), the distance between the reed switch 31 and the permanent magnet structure 4 increases. When the distance increases to a preset threshold, the reed switch 31 stops working, and the monitoring chip 5 collects the working information of the reed switch 31 and transmits the working information of the reed switch 31 to the external terminal through the communication module 7. In one or more embodiments, both the pole 1 and the detector mounting rod 32 are equipped with anti-tipping devices 6 at the ends facing the road shoulder, improving the connection stability of the pole 1 and the detector mounting rod 32 when connected to the roadbed. Figure 1 As shown.

[0029] In one or more embodiments, the anti-tipping device 6 body is a fork-shaped structure. By designing the anti-tipping device 6 as a fork-shaped structure, it can form multi-point support when the pole 1 is inserted into the road shoulder, increasing the contact area and friction with the foundation, and effectively improving the stability of the speed limit sign 2. Furthermore, the anti-tipping device 6 includes a crossbar, one end of which is connected to the upright post 1 and / or the detector mounting post 32. A vertical post is provided at the bottom of the crossbar, and the end of the vertical post away from the crossbar is tapered, such as... Figure 1 As shown.

[0030] In one or more embodiments, the outer surface of the pole 1 is provided with an anti-corrosion layer. By providing an anti-corrosion layer on the outer surface of the pole 1, the corrosion of the pole 1 by rainwater, moisture and other harsh environments can be effectively resisted, thus extending the service life of the device.

[0031] In one or more embodiments, the surface of the speed limit sign 2 is provided with a reflective layer. By providing a reflective layer on the surface of the speed limit sign 2, the train headlights can be reflected at night or in low visibility environments such as rain and fog, enabling the train driver to identify the speed limit information in a timely and clear manner, improving the visual confirmation effect, and thus further ensuring the safety and reliability of train operation.

[0032] In one or more embodiments, the monitoring chip 5 includes a data acquisition module for acquiring the operating information of the reed switch, such as... Figure 2 As shown.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
