Description

Technical Field

[0001] This invention relates to the field of communication signal detection technology, specifically to a high-speed rail communication signal detection device and method. Background Technology

[0002] High-speed rail communication signal detection devices are crucial safety equipment in the high-speed rail operation system. They are used to monitor and analyze the strength and stability of high-speed rail signals, thereby ensuring the normal operation of the high-speed rail communication signal system.

[0003] For example, the patent disclosed in the prior art with publication number "CN115051767B" is entitled "A 5G Communication Signal Testing Method." It discloses that when it is necessary to remove the interference simulation device from the storage box, the locking rod is first pulled out from the lifting storage plate by hand. Under the action of the return spring at its bottom, the lifting storage plate bounces upward along the inner wall of the storage box, thereby causing the interference simulation device to pop out of the storage box. The operator then removes the device from the limiting enclosure and performs signal testing. After the signal test is completed, the operator puts the interference simulation device back into the cavity of the limiting enclosure and then presses down the handle, causing the lifting storage plate to drop in height. At the same time, pressing down the handle causes the sealing slide plate at its top to move downward synchronously, sealing the handle groove through the sealing slide plate. Another example is the prior art with publication number "C..." The patent disclosed in N217486500U, entitled "A Novel High-Speed ​​Rail Communication Signal Detection Device," describes a method where a battery provides temporary power to the detector, ensuring it continues monitoring even after a power outage. A solar charging panel charges the battery, extending the detector's operating time after a power outage. When the surface of the solar charging panel becomes dusty, a water pump is activated, drawing water from the tank and injecting it into multiple nozzles via an inlet pipe. These nozzles spray water to clean the surface of the solar charging panel. The resulting wastewater flows along one side of the mounting plate into a receiving hopper, then through a drain pipe into a filter box. The wastewater passes through large and small particle filters to remove particles of varying sizes. The filtered water then flows back into the water tank via a return pipe for reuse.

[0004] When the existing high-speed rail communication signal detection device is installed beside the track, the high-speed train moves the surrounding air at high speed, generating a large wind. Since the device simply uses a support rod to support the detector, the wind can blow the support rod and the detector, affecting the stability of the installation and thus the detection and monitoring of high-speed rail communication signals. Therefore, we propose a high-speed rail communication signal detection device and method to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a high-speed rail communication signal detection device and method to solve the problem mentioned in the background art. When the high-speed rail train is used at high speed, it causes the surrounding air to move, generating a large wind. Since the above-mentioned devices simply use support rods to support and install the detector, the wind blows on the support rods and detectors, affecting the stability of the support rods and detectors, and thus affecting the detection and monitoring of high-speed rail communication signals.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed rail communication signal detection device, comprising a fixed base plate for installation beside the track, wherein a supporting telescopic rod is fixed at the upper middle position of the fixed base plate, and a solar panel is connected to the upper end of the supporting telescopic rod; a signal detector is installed on the outer side of the supporting telescopic rod via a bearing frame, and an antenna body is connected above the signal detector; a fixed frame is installed on the fixed base plate corresponding to the front and rear sides of the supporting telescopic rod; a first rack plate and a second rack plate are slidably connected within the fixed frame; a plastic plate is connected to the left side of the first rack plate; the first rack plate is connected to the second rack plate via an adjustment component installed within the fixed frame; a vertical plate is installed on one side of the second rack plate via a connecting block; and an auxiliary plate is installed on the inner side of the vertical plate via an elastic connector.

[0007] Preferably, the control component includes a control rod installed in the fixed frame, and a spiral spring is nested on the outer side of the upper end of the control rod. A control gear is installed on the outer side of the middle part of the control rod, and the control gear is meshed with the first rack plate and the second rack plate. The first rack plate and the second rack plate are symmetrically arranged about the center line of the control gear, and a connecting block installed on one side of the second rack plate is slidably connected to a slot opened in one side of the fixed frame.

[0008] Preferably, the auxiliary plates on the two vertical plates on the right are arranged in an alternating vertical arrangement, and there is a gap between two adjacent auxiliary plates.

[0009] Preferably, through slots are provided in the fixed base plates on the left and right sides of the support telescopic rod.

[0010] Preferably, the elastic connector includes a sleeve connected to the vertical plate, and a first piston rod is fitted inside one end of the sleeve. The end of the first piston rod near the sleeve is connected to a first connecting spring installed inside the sleeve. The end of the first piston rod away from the sleeve is connected to an arc-shaped auxiliary plate. A guide tube is installed through the end of the sleeve near the vertical plate.

[0011] Preferably, a vertical tube is installed inside the vertical plate, and a cylindrical groove is opened inside the bottom surface of the vertical plate. A second piston rod is fitted inside the groove, the upper end of the second piston rod is connected to a second connecting spring installed inside the groove, the lower end of the vertical tube is inserted into the groove, the other end of the guide tube is connected to the inside of the vertical tube, and a friction block is connected to the lower end of the second piston rod. The friction block is set inside the through groove.

[0012] Preferably, the control rod on the rear side of the support telescopic rod passes through the upper surface of the rear fixed frame, and an active gear is installed on the upper outer side of the control rod on the rear side.

[0013] Preferably, a driven gear is rotatably mounted on the outer side of the supporting telescopic rod, and a driving gear is meshed with the rear side of the driven gear. An "L"-shaped connecting post is mounted on the upper outer side of the driven gear, and the upper end of the connecting post is connected to a protective baffle sleeved on the outside of the antenna body. The protective baffle is circular, and a through groove is opened in the inner side of the protective baffle near the antenna body. The rotation angle of the protective baffle is 180°.

[0014] Preferably, the diameter of the driven gear is larger than the diameter of the driving gear.

[0015] Another technical solution provided by the present invention is a detection method for a high-speed rail communication signal detection device, comprising the following steps:

[0016] S1: Install the fixed base plate next to the track, and then the signal detector and the antenna body work together to monitor the status of track circuits, signals, switch machines and other equipment in real time, and monitor the quality of communication networks such as railway dedicated mobile communication systems;

[0017] S2: If the parameters are found to be outside the normal range, the signal detector will send an alarm message to the monitoring center, so that technicians can handle the fault later. The solar panel provides power to the signal detector.

[0018] S3: When the high-speed train is traveling at high speed on the track, the wind automatically pushes the two lighter plastic plates towards the fixed frame. The control component moves the auxiliary plate installed on the right vertical plate to make contact with the outer side of the support telescopic rod.

[0019] S4: The arc-shaped auxiliary plates on the two vertical plates on the right side apply a certain abutment force to the support telescopic rod, thereby improving the overall wind resistance of the support telescopic rod and facilitating the monitoring operation of the support telescopic rod and signal detector.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The high-speed rail communication signal detection device and method apply a certain abutment force to the supporting telescopic rod through the auxiliary plate on the right side, thereby improving the overall wind resistance of the supporting telescopic rod. Therefore, it is convenient to improve the stability of the signal detector during installation and use, and avoids affecting the detection and monitoring of high-speed rail communication signals by the signal detector. The specific details are as follows:

[0021] (1) When the high-speed train is running at high speed, the large wind will push the two plastic plates to move towards the fixed frame. Then, by adjusting the gear settings, the first rack plate and the second rack plate move in opposite directions. Therefore, the second rack plate can drive the auxiliary plate on the right side to move towards the support telescopic rod, so that the auxiliary plate on the right side can apply a certain resistance force to the support telescopic rod, thereby improving the overall wind resistance of the support telescopic rod. Therefore, it is convenient to improve the stability of the signal detector during installation and use, and avoid affecting the detection and monitoring of the high-speed rail communication signal by the signal detector.

[0022] (2) Furthermore, when the auxiliary plate on the right side squeezes the first piston rod, the first piston rod delivers the gas in the sleeve to the vertical pipe through the guide pipe, and then the gas in the vertical pipe enters the groove inside the vertical plate, thereby pushing the second piston rod and the friction block to move downward, so that the rubber pad on the bottom surface of the friction block is in close contact with the ground next to the track, which can further improve the overall wind resistance of the support telescopic rod.

[0023] (3) When the control lever rotates, the active gear drives the driven gear with a larger diameter to rotate, which in turn drives the protective baffle in the shape of a ring to rotate. This makes it easier for the protective baffle to shield the left side of the antenna body, preventing the antenna body from being blown off and damaged by strong winds. Therefore, it can further protect the signal detector and prevent it from affecting the detection and monitoring of high-speed rail communication signals. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-11 The present invention provides the following technical solution:

[0038] Example 1: The high-speed rail communication signal detection device and method in this example can improve the wind resistance of the supporting telescopic pole 2, thereby facilitating the stable installation and placement of the signal detector 3 on the supporting telescopic pole 2. This allows the signal detector 3 to effectively detect and monitor high-speed rail communication signals. The specific structure is shown in the attached diagram. Figures 1-9As shown, the system includes a fixed base plate 1 for installation beside the track, and a support telescopic rod 2 is fixed at the upper middle position of the fixed base plate 1. A solar panel 5 is connected to the upper end of the support telescopic rod 2. A signal detector 3 is installed on the outer side of the support telescopic rod 2 through a carrier frame, and an antenna body 4 is connected above the signal detector 3. Fixed frames 6 are installed on the fixed base plate 1 on the front and rear sides of the support telescopic rod 2. A first rack plate 7 and a second rack plate 15 are slidably connected inside the fixed frames 6. A plastic plate 8 is connected to the left side of the first rack plate 7. The first rack plate 7 is connected to the second rack plate 15 through an adjustment component installed in the fixed frames 6. A vertical plate 11 is installed on one side of the second rack plate 15 through a connecting block. An auxiliary plate 14 is installed on the inner side of the vertical plate 11 through an elastic connector.

[0039] The control assembly includes a control rod 13 installed within the fixed frame 6, with a spiral spring 133 nested on the outer side of the upper end of the control rod 13. A control gear 132 is installed on the outer side of the middle portion of the control rod 13, and both control gears 132 mesh with the first rack plate 7 and the second rack plate 15. The first rack plate 7 and the second rack plate 15 are symmetrically arranged about the center line of the control gear 132. A connecting block installed on one side of the second rack plate 15 is slidably connected to a slot opened in one side of the fixed frame 6. Auxiliary plates 14 on the two vertical plates 11 on the right side are staggered vertically, with a gap between adjacent auxiliary plates 14. Through slots 101 are opened in the fixed base plates 1 on the left and right sides of the support telescopic rod 2. The elastic connector includes a sleeve 16 connected to the vertical plate 11, and one side of the sleeve 16... A first piston rod 161 is fitted inside the sleeve 16, and the end of the first piston rod 161 near the sleeve 16 is connected to a first connecting spring 162 installed inside the sleeve 16. The end of the first piston rod 161 away from the sleeve 16 is connected to an arc-shaped auxiliary plate 14. A guide pipe 163 is installed through the end of the sleeve 16 near the vertical plate 11. A vertical pipe 18 is installed inside the vertical plate 11, and a cylindrical groove is opened inside the bottom surface of the vertical plate 11. A second piston rod 17 is fitted inside the groove. The upper end of the second piston rod 17 is connected to a second connecting spring 171 installed inside the groove. The lower end of the vertical pipe 18 is inserted into the groove. The other end of the guide pipe 163 is connected to the interior of the vertical pipe 18. A friction block 12 is connected to the lower end of the second piston rod 17. The friction block 12 is set in the through groove 101.

[0040] First, multiple high-speed rail communication signal detection devices are moved to the side of the track and installed at fixed intervals using a fixed base plate 1, allowing the high-speed rail to move forward or backward to the left of the signal detector 3. Then, the signal detector 3, in conjunction with the antenna body 4, monitors the status of equipment such as track circuits, signals, and switch machines in real time, and monitors the quality of communication networks such as the railway dedicated mobile communication system. If parameters are found to be outside the normal range, the signal detector 3 will send an alarm message to the monitoring center. The signal detector 3 can automatically identify system anomalies and locate fault points. At the same time, the signal detector 3 can store historical data for analysis and accident investigation, facilitating subsequent fault handling by technicians. It can detect potential problems in advance and issue early warnings to avoid accidents. If the battery inside the signal detector 3 is depleted, it can be powered by a solar panel 5. Since this part is existing technology, it will not be described in detail here.

[0041] When a high-speed train travels at high speed on the track, a strong wind is generated. This wind automatically pushes the two lighter plastic plates 8 towards the fixed frame 6. The two plastic plates 8 then move the two first rack plates 7. The first rack plates 7 slide stably within the grooves of the fixed frame 6 via sliders on their upper and lower sides. The first rack plates 7 drive the adjusting gear 132 and the adjusting rod 13 to rotate, and the spiral spring 133 stores energy. When the adjusting gear 132 rotates, it drives the second rack plate 15 to move to the left. The second rack plate 15 slides stably within the grooves of the fixed frame 6 via sliders on its upper and lower sides. The second rack plate 15, through a connecting block that slides through a groove on the inner side of the fixed frame 6, drives the two sets of vertical plates 11 to move to the left. At this time, the auxiliary plate 14 installed on the right vertical plate 11 moves to contact the outer side of the supporting telescopic rod 2. The auxiliary plates 14 on the two right vertical plates 11 are staggered, so that the arc-shaped auxiliary plates 14 on both right vertical plates 11 exert a certain amount of contact with the supporting telescopic rod 2. The support force can improve the overall wind resistance of the support telescopic rod 2, thus facilitating the stability of the signal detector 3 during installation and use, and avoiding affecting the detection and monitoring of high-speed rail communication signals by the signal detector 3. At the same time, when the auxiliary plate 14 on the right side contacts the support telescopic rod 2 and continues to move to the left, the auxiliary plate 14 on the right side will push the first piston rod 161 into the sleeve 16. At this time, the first connecting spring 162 stores force, and the gas in the sleeve 16 enters the vertical pipe 18 through the guide pipe 163. Then, the gas in the vertical pipe 18 enters the groove opened inside the vertical plate 11, so that the gas automatically pushes the second piston rod 17 to move downward. The second piston rod 17 drives the friction block 12 to move downward. Then, the friction block 12 with rubber pads installed on the bottom surface moves downward in the through groove 101 and makes close contact with the ground next to the track. Therefore, the overall wind resistance of the support telescopic rod 2 can be further improved, which facilitates the stable support and installation of the signal detector 3 by the support telescopic rod 2, so that the support telescopic rod 2 and the signal detector 3 can be used well.

[0042] Meanwhile, since vertical plates 11 and auxiliary plates 14 are installed on both the left and right sides of the second rack plate 15, when the high-speed train is running, if a low-pressure suction area is generated at the rear or front of the train, the suction force generated will drive the two first rack plates 7 to move to the left. Then, as shown above, the auxiliary plate 14 on the left side can apply abutment support force to the support telescopic rod 2. Since the wind generated by the high-speed train is mainly blowing wind, the suction force generated is short-lived, so this part will not be described in detail.

[0043] Example 2: The high-speed rail communication signal detection device and method in this example, based on Example 1, can protect the antenna body 4 to prevent damage to the antenna body 4 caused by strong winds. The specific structure is shown in the attached diagram. Figures 10-11As shown, the adjustment rod 13 on the rear side of the support telescopic rod 2 passes through the upper surface of the fixed frame 6 on the rear side, and an active gear 131 is installed on the upper outer side of the adjustment rod 13 on the rear side. A driven gear 19 is rotatably installed on the outer side of the support telescopic rod 2, and the driven gear 131 is meshed with the rear side of the driven gear 19. An "L"-shaped connecting post 10 is installed on the upper outer side of the driven gear 19, and the upper end of the connecting post 10 is connected to the protective baffle 9 sleeved on the outside of the antenna body 4. The protective baffle 9 is arranged in a ring shape, and a through groove 91 is opened in the inner side of the protective baffle 9 near the antenna body 4. The rotation angle of the protective baffle 9 is 180°, and the diameter of the driven gear 19 is larger than the diameter of the active gear 131.

[0044] When the control rod 13 in the fixed frame 6 on the rear side drives the drive gear 131 to rotate, the drive gear 131 drives the driven gear 19 with a larger diameter to rotate. At this time, the driven gear 19 drives the protective baffle 9 to rotate through the connecting column 10, so that the through slot 91 opened in the protective baffle 9 rotates to the right side of the antenna body 4. Therefore, the left side of the protective baffle 9 effectively blocks the wind from the left side of the antenna body 4, preventing the wind from blowing the antenna body 4 off and damaging it. This further protects the signal detector 3 and prevents it from affecting the detection and monitoring of high-speed rail communication signals.

[0045] To better demonstrate the specific detection method of the high-speed rail communication signal detection device, this embodiment describes a detection method for a high-speed rail communication signal detection device, including the following steps:

[0046] Step 1: Install the fixed base plate 1 next to the track, and then the signal detector 3 and the antenna body 4 work together to monitor the status of track circuits, signals, switch machines and other equipment in real time, and monitor the quality of communication networks such as railway dedicated mobile communication systems;

[0047] Step 2: If the parameters are found to be outside the normal range, the signal detector 3 will send an alarm message to the monitoring center, so that technicians can handle the fault later. The solar panel 5 provides power to the signal detector 3.

[0048] Step 3: When the high-speed train is traveling at high speed on the track, the two lighter plastic plates 8 are automatically pushed by the wind to move towards the fixed frame 6. The auxiliary plate 14 installed on the right vertical plate 11 is moved to contact the outer side of the support telescopic rod 2 by the control component.

[0049] Step 4: The arc-shaped auxiliary plates 14 on the two vertical plates 11 on the right side apply a certain abutment support force to the support telescopic rod 2, thereby improving the overall wind resistance of the support telescopic rod 2 and facilitating the support telescopic rod 2 and the signal detector 3 to perform monitoring operations well.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
