Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a railway track monitoring system. Background Art

[0002] In the railway signal electrical centralized station or section block system, the railway uses two steel rails as conductors to transmit the signal information of the track circuit. When a train or vehicle is in the track circuit section, a short circuit is formed between the two steel rails, and the action voltage of the track relay module in the track circuit is reduced, so that the track relay module falls, and the signal interlocking system knows that there is a vehicle occupying the section to ensure that no more vehicles can enter the section. However, in some special sections in the station, such as the crossover or siding at the entrance of the double-track section, after a long period of no vehicles, the track surface rusts, resulting in poor track circuit branching, and the signal system cannot accurately determine whether there is a vehicle in the section, resulting in potential accidents.

[0003] In view of the problem of poor track circuit shunt, the existing technology focuses on how to discover and solve this problem, and does not provide a solution for how to ensure the continued safe operation of the railway when the poor track circuit shunt occurs. For example, the Chinese patent with publication number CN112606866B discloses a detection method and device for poor track circuit shunt. It specifically discloses that the detection operation device walks on the track to simulate the train to detect the track circuit shunt state. The detection body collects the shunt voltage in time through the voltage sensor and compares it with the set value. If the actual value is lower than the set value, the detection body sends an audible and visual alarm through the alarm module to indicate that the track circuit shunt is poor. After the poor shunt fault is determined, it is recorded in time and the relevant team is notified to carry out maintenance, which requires a lot of manpower, material resources and time.

[0004] At present, if the track circuit is poorly divided and cannot be resolved in a short time, staff are required to confirm on site whether there are any vehicles in the section, which increases the number of times staff go on the track and the risk factor. Especially in severe weather conditions, the labor intensity is high and the efficiency is low. Utility Model Content

[0005] The utility model provides a railway track monitoring system, which is easy to deploy and low in cost, can replace manual on-site confirmation, and can correctly determine whether the track is occupied even if a bad track circuit branch occurs, thereby eliminating potential accident hazards.

[0006] The utility model provides a railway track monitoring system, comprising a monitoring station arranged beside the steel rail and a monitoring device arranged in an operation room, wherein the monitoring station comprises an electrical cabinet and a detection module, a communication module and a control module arranged on the electrical cabinet, the detection module and the communication module are both connected to the control module, the detection module detects the space above the steel rail, the angle between the orientation of the detection module and the laying direction of the steel rail is an acute angle, and the communication module is used for sending the detection result to the monitoring device.

[0007] In one embodiment, the electrical cabinet includes an outer cabinet and an inner cabinet disposed inside the outer cabinet, the communication module and the control module are both disposed inside the inner cabinet, and the detection module is disposed outside the outer cabinet.

[0008] In one embodiment, a plurality of ventilation holes are provided on the outer cabinet.

[0009] In one embodiment, the monitoring station further comprises a solar panel disposed on the top of the outer cabinet, and a battery connected to the solar panel is disposed inside the inner cabinet.

[0010] In one embodiment, a solar controller connected to the battery is also provided inside the inner cabinet.

[0011] In one embodiment, a mounting frame is provided on the top of the outer cabinet, and the solar panel is obliquely arranged on the mounting frame.

[0012] In one embodiment, the monitoring station further comprises a bracket, the top of the bracket is connected to the top of the electrical cabinet, and the bottom of the bracket is fixed to the ground by bolts.

[0013] In one embodiment, the detection module is a radar.

[0014] In one embodiment, the monitoring station is arranged close to the warning mark, and the distance between the monitoring station and the warning mark is greater than 500 mm and less than 3000 mm.

[0015] In one embodiment, the distance between the monitoring station and the rail is greater than 500 mm.

[0016] Compared with the prior art, the utility model has the advantage that when a train occupies the rail, the detection module installed on the monitoring station beside the rail can detect the train and send the corresponding signal to the control module, which then sends the corresponding signal to the monitoring device in the operation room through the communication module for the staff to view. The railway track monitoring system of the utility model operates independently of the existing interlocking equipment. Even if the track circuit shunt is poor, it can provide early warning information in real time to avoid safety accidents. It can replace manual on-site confirmation, effectively reduce labor intensity, and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 4 As shown, a railway track monitoring system according to an embodiment of the utility model includes a monitoring station 1 arranged next to a rail 100 and a monitoring device 2 arranged in an operating room 200. The monitoring station 1 includes an electrical cabinet 11 and a detection module 12, a communication module 13 and a control module 14 arranged on the electrical cabinet 11. The detection module 12 and the communication module 13 are both connected to the control module 14. The detection module 12 faces the rail 100 and detects the space above the rail 100. The communication module 13 is used to send the detection result to the monitoring device 2.

[0026] In this embodiment, the detection module 12 is a radar. When the rail 100 is occupied by a train 300, the detection module 12 arranged on the monitoring station 1 next to the rail 100 can detect the train 300 and send a corresponding signal to the control module 14. The control module 14 then sends the corresponding signal to the monitoring device 2 in the operation room 200 through the communication module 13 for the staff to view. The railway track monitoring system of this embodiment operates independently of the existing interlocking equipment. Even if the track circuit shunt is poor, it can provide early warning information in real time to avoid safety accidents. It can replace manual on-site confirmation, effectively reduce labor intensity, and improve work efficiency.

[0027] like Figure 1 As shown, the monitoring station 1 is placed at a certain angle relative to the rail 100. The purpose is to make the direction of the detection module 12 on the monitoring station 1 form an angle α with the laying direction of the rail 100. The angle α is an acute angle, for example 30 degrees, so that the detection module 12 can detect a larger space above the rail 100 and more accurately determine whether the rail 100 is occupied.

[0028] like Figure 4 As shown, the electrical cabinet 11 includes an outer cabinet 111 and an inner cabinet 112 disposed inside the outer cabinet 111, the communication module 13 and the control module 14 are both disposed inside the inner cabinet 112, and the detection module 12 is disposed outside the outer cabinet 111. The electrical cabinet 11 adopts such a structure so that the components in the inner cabinet 112 can be fully protected, providing good guarantee for its normal operation, effectively resisting relatively severe weather conditions such as external wind and rain, and improving the stability of the equipment.

[0029] like Figure 3 As shown, further, a plurality of ventilation holes 1111 are opened on the outer cabinet body 111, and the ventilation holes 1111 can discharge the heat generated by the operation inside the electrical cabinet 11 more quickly, thereby preventing the equipment inside the electrical cabinet 11 from being damaged due to excessive temperature.

[0030] The monitoring station 1 further includes a solar panel 15 disposed on the top of the outer cabinet 111, and a battery 16 connected to the solar panel 15 is disposed inside the inner cabinet 112. The solar panel 15 can charge the battery 16, so that the monitoring station 1 can solve the power supply problem by itself, without the need to set up additional cables for power supply, thereby reducing the deployment cost and improving the flexibility of the deployment of the monitoring station 1.

[0031] Furthermore, a solar controller 17 connected to the battery 16 is also provided inside the inner cabinet 112. The solar controller 17 can accurately adjust the voltage, realize intelligent charging and discharging, keep the battery 16 in a better operating state, and provide a stable power supply for various devices.

[0032] like Figure 2 and Figure 4 As shown, a mounting frame 18 is provided on the top of the outer cabinet 111 , and the solar panel 15 is tiltedly arranged on the mounting frame 18 , so that the solar panel 15 can receive more sufficient sunlight and provide more electric energy for the battery 16 .

[0033] like Figures 2 to 4 As shown, the monitoring station 1 further includes a bracket 19, the top of the bracket 19 is connected to the top of the electrical cabinet 11, and the bottom of the bracket 19 is fixed to the ground by bolts 20. The bracket 19 allows the electrical cabinet 11 to be at a certain height from the ground, and the detection module 12 is not easily blocked by ground objects, and can accurately determine whether there is a train 300 on the rail 100. The bracket 19 is fixed by bolts 20, so that the monitoring station 1 can be stably fixed on the ground and is not easy to tip over.

[0034] like Figure 1 As shown, the monitoring station 1 is arranged near the warning mark 400, and the distance between the monitoring station 1 and the warning mark 400 is greater than 500 mm and less than 3000 mm. The monitoring station 1 is arranged near the warning mark 400, so that the detection module 12 can measure the distance between the train 300 and the warning mark 400, thereby determining whether the train 300 has passed the warning mark 400, avoiding manual on-site confirmation and reducing labor intensity.

[0035] In this embodiment, the distance between the monitoring station 1 and the rail 100 is greater than 500 mm, so as to leave a certain safety distance and reduce the probability of the monitoring station 1 being damaged.

[0036] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
