Description

Technical Field

[0001] The present invention relates to the technical field of railway signal detection for comprehensive detection trains, and in particular to a railway color light signal display distance detection device, a mainboard unit and a method for detecting the distance of the railway color light signal applied to ordinary speed comprehensive detection trains. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. No statement herein is admitted to be prior art by virtue of its inclusion in this section.

[0003] Conventional railways, also known as ordinary speed railway systems, are defined as non-passenger dedicated lines with speeds of no more than 160km / h and passenger dedicated lines with speeds of no more than 140km / h. Compared to the CTCS-2 / 3 high-speed railway train control system, conventional railway line data is stored in an onboard database, and fixed blocks are mostly used in sections, equipped with color light signals. When the train is running, the driver mainly relies on the display of ground color light signals, supplemented by locomotive signals. The display distance of color light signals refers to the distance that can be displayed by various signal lights and signal indicators along the railway, that is, the distance at which the train driver can effectively visually observe and judge the display status of the signal lights. Generally speaking, the display of signal lights should be as far as possible, so that approaching trains can see the display as uninterrupted as possible.

[0004] However, because signals are installed above ground, the distance a train driver can effectively visually observe and judge the signal's display status can be shortened due to factors such as the signal's installation angle, the technical state of the circuit and optical path, obstructions caused by line construction, and terrain. This can hinder the driver's ability to take timely action, leading to late braking or overly cautious driving, resulting in low speeds and negatively impacting operational efficiency. Therefore, periodic verification of the display distance of color light signals is a routine maintenance task for conventional railway signals. However, due to site conditions, this task consumes significant human resources, results in infrequent inspections, and less-than-ideal results.

[0005] To address the above issues, no effective solutions have been proposed so far. Summary of the Invention

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0035] The inventors discovered that, aside from manual inspections, conventional railway infrastructure status monitoring currently relies primarily on routine dynamic testing of tracks, overhead lines, and electrical inspection vehicles. This dynamic testing provides data support for routine maintenance work at grassroots maintenance units (stations and sections), and provides a basis for the head office and railway bureau's various functional departments to comprehensively monitor the technical status of on-site equipment and oversee and evaluate the performance of subordinate units.

[0036] In order to comprehensively improve the efficiency of dynamic inspection of conventional railways; support the multi-disciplinary integrated analysis of the industrial and electrical supply of conventional railways to solve the problems of insufficient comprehensive utilization and mining analysis of data among various disciplines, and adapt to the integration of industrial and electrical supply and maintenance; at the same time, solve the problem that the centralized power EMU platform is gradually put into use, and trailer inspection on some railways has become a problem. The research and development of comprehensive inspection trains for conventional railways is put on the agenda.

[0037] Conventional railway comprehensive inspection trains integrate specialized inspection functions for track, catenary, and electrical services on a unified vehicle platform. In addition to existing inspections of trackside signaling equipment (track circuits, transponders, compensation capacitors, and traction return current), they can also supplement the inspection of distance displayed by color-coded signaling equipment.

[0038] Display distances of various signal lights under normal circumstances:

[0039] a) The distance between the entry, passing, approaching and blocking signals shall not be less than 1000m;

[0040] b) High-post signal machines and high-post approach signal machines shall not be less than 800m;

[0041] c) Advance signal, hump signal and hump auxiliary signal shall not be less than 400m;

[0042] d) The distance between shunting, low-profile entry, low-profile exit, low-profile approach, low-profile passing, repeater signals, permission and guide signals and various indicators shall not be less than 200m.

[0043] The railway color light signal display distance detection device is a subsystem of the signal dynamic detection system. Installed in the driver's cab of a conventional speed comprehensive inspection train, the device collects signals along the train's route while the train is performing inspections. Because the inspection train operates based on "train signals," its detection targets primarily include high-post and low-profile entry, passing, advance, approach, and repeater signals. Shunting signals on shunting approaches, as well as hump and auxiliary hump signals in hump shunting yards, are not within the detection range.

[0044] Figure 1 FIG. 1 is a schematic diagram of a structure of a railway color light signal display distance detection device according to an embodiment of the present invention. Figure 1 As shown, the railway color light signal display distance detection device in the embodiment of the present invention may include:

[0045] Industrial camera assembly 101, used to collect image data of railway color light signal machines and cables;

[0046] The camera bracket assembly 102 is movably connected to the industrial camera assembly 101 and is used to fix and adjust the horizontal direction and pitch angle of the industrial camera assembly 101;

[0047] The image data interface 103 is used to receive image data transmitted by the industrial camera assembly 101 and transmit the image data to the mainboard unit 106;

[0048] Positioning data interface 104, used to receive positioning data of ordinary speed comprehensive inspection trains and transmit the positioning data to the main board unit 106;

[0049] The input / output interface 105 is used to obtain the initial data of the detection task, configure the initial parameters of the detection task, transmit the initial data and initial parameters of the detection task to the mainboard unit 106, and receive and display the detection results of the mainboard unit 106;

[0050] The mainboard unit 106 is used to determine the detection result of the display distance of the railway color light signal based on the image data, positioning data, initial data of the detection task, and initial parameters of the detection task, and send the detection result to the input and output interface 105. The display distance is the distance at which the ordinary speed comprehensive detection train captures the display status of the railway color light signal.

[0051] In one embodiment, a battery unit may also be included for providing power to the railway color light signal display distance detection device when there is no external power supply.

[0052] In one embodiment, when the conventional speed comprehensive inspection train is of a centralized power type, the railway color light signal display distance detection device can be fixed on the operating console in the driver's cab and powered by the inspection train; when the conventional speed comprehensive inspection train is of a traction type, the railway color light signal display distance detection device can be temporarily fixed on the operating console in the driver's cab through a self-priming chassis and powered by a battery unit.

[0053] Since ordinary speed comprehensive inspection trains run according to "train signals", there is no need to judge the road conditions based on the display distance of the railway color light signal. During safe driving, the railway color light signal display distance detection device installed on them can be used to detect whether the display distance of the railway color light signal meets the standards.

[0054] In a specific implementation, when the railway color light signal display distance detection device is applied, the industrial camera component can first collect image data of the railway color light signal and the cable, and transmit the image data of the railway color light signal and the cable to the image data interface, and then transmit the image data of the railway color light signal and the cable to the mainboard unit by the image data interface, wherein the camera bracket component is movably connected to the industrial camera component for fixing and adjusting the horizontal pointing and pitch angle of the industrial camera component;

[0055] In addition, the positioning data interface can receive the positioning data of the conventional speed comprehensive inspection train and transmit the positioning data to the main board unit; the input and output interface can obtain the initial data of the inspection task, configure the initial parameters of the inspection task, and then transmit the initial data and initial parameters of the inspection task to the main board unit, where the initial data and initial parameters of the inspection task can include the inspection basic information database, signal feature database, etc.

[0056] In one embodiment, when the conventional speed comprehensive inspection train is a power-centralized type, the positioning data can be provided by the time and space synchronization system of the conventional speed comprehensive inspection train; when the conventional speed comprehensive inspection train is a traction type, the positioning data can be provided by the train operation monitoring and recording device LKJ installed on the conventional speed comprehensive inspection train.

[0057] The LKJ Train Operation Monitoring and Recording Device is a train speed monitoring device developed by the railway industry primarily to ensure train operation safety. While ensuring safe train speed control, it also collects and records various locomotive operating status information relevant to safe train operation, promoting the automation of locomotive operation management. The device utilizes dual-unit hot standby redundancy, resulting in more reliable performance. The device's screen displays information such as the line status and operational status in graphical, graphical, and text formats. It also automatically applies emergency braking in dangerous situations such as overspeeding or running through a red light, ensuring railway transportation safety.

[0058] Finally, the mainboard unit can determine the detection result of the display distance of the railway color light signal based on the image data, positioning data, initial data of the detection task, and initial parameters of the detection task, and send the detection result to the input and output interface so that the input and output interface displays the detection result of the mainboard unit, where the display distance is the distance at which the ordinary speed comprehensive detection train captures the display status of the railway color light signal.

[0059] In one embodiment, the mainboard unit can be specifically used to: identify the type of the current railway color light signal according to the image data; determine the standard display distance of the current railway color light signal according to the type of the current railway color light signal, the initial data of the detection task, and the initial parameters of the detection task; determine the actual display distance of the current railway color light signal according to the image data and the positioning data of the conventional speed comprehensive detection train; compare the actual display distance of the current railway color light signal with the standard display distance of the current railway color light signal; when the actual display distance of the current railway color light signal is not less than its standard display distance, determine that the detection result of the display distance of the current railway color light signal is passed.

[0060] In one embodiment, the mainboard unit can also be used to: predict the type and location of the next railway color light signal based on the positioning data; and control the adjustment of the initial data and initial parameters of the detection task based on the predicted type and location of the next railway color light signal.

[0061] During specific implementation, the mainboard unit can determine the standard display distance and actual display distance of the current railway color light signal machine based on the various data obtained in real time, the pre-entered basic detection data, and the pre-configured detection parameters. At the same time, it can also predict the type and position of the next railway color light signal machine based on the positioning data of the conventional comprehensive detection train, and according to the predicted type and position of the next railway color light signal machine, timely control the adjustment of data and parameters to quickly detect various railway color light signal machines along the route.

[0062] Different types of railway color light signals indicate different road conditions ahead, such as high-column and low-type entry, passing, warning, approaching, etc. Each type of railway color light signal corresponds to a different standard display distance, where the standard display distance is the minimum distance to ensure that the train driver can effectively visually observe and judge the display status of the signal. If the railway color light signal display distance detection device determines that the actual display distance of the current railway color light signal is greater than or equal to its corresponding standard display distance, it means that the railway color light signal can pass the test; if the railway color light signal display distance detection device determines that the actual display distance of the current railway color light signal is less than its corresponding standard display distance, it means that the railway color light signal has failed the test and the railway color light signal needs to be adjusted in time to ensure the safety of subsequent trains.

[0063] Figure 2 This diagram illustrates a specific example of a railway color light signal display distance detection device, according to an embodiment of the present invention, applied to a power-centralized conventional speed integrated inspection train. This power-centralized conventional speed integrated inspection train utilizes a fixed train formation, providing the possibility of providing an external power source and a wired data channel for the color light signal display distance detection device. The device can be mounted on the operator's console in the driver's cab and powered directly by the inspection train. The conventional speed integrated inspection train's positioning data required by the device is provided by the inspection train's spatiotemporal synchronization system. The initial data and parameters required for the inspection task are provided by an industrial control computer via a network.

[0065] The industrial camera assembly 201 and the camera bracket assembly 202 transmit the collected image data of the railway color light signal and cables to the image data interface 205 in the image processing subsystem 204; the image data interface 205 transmits the image data of the railway color light signal and cables to the main board unit 207; the time and space synchronization system 203 transmits the positioning data of the ordinary speed comprehensive inspection train to the positioning data interface 206; the positioning data interface 206 transmits the positioning data of the ordinary speed comprehensive inspection train to the main board unit 207; the industrial control computer 209 transmits the initial data and initial parameters of the inspection task to the main board unit 207 through the network switch 208; the main board unit 207 determines the detection result of the display distance of the railway color light signal based on the image data, positioning data, initial data of the inspection task, and initial parameters of the inspection task, and transmits the detection result of the display distance of the railway color light signal to the industrial control computer 209 through the network switch 208 to provide it to the inspection personnel through its display interface.

[0066] Figure 3 The figure is a schematic diagram of a specific example of the railway color light signal display distance detection device applied to a traction-type conventional speed comprehensive inspection train in an embodiment of the present invention. The traction-type conventional speed comprehensive inspection train adopts a temporary formation and does not have the possibility of providing an external power supply and a wired data channel for the color light signal display distance detection device. When in use, it is necessary to replace the device with a self-priming chassis, and temporarily fix it to the operating console in the driver's cab through the self-priming chassis. The device is powered by a built-in battery; at the same time, a train operation monitoring and recording device LKJ is installed at the interface of the traction locomotive. The device can receive and send LKJ data (partial data) wirelessly.
