Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a system and method for a shared test track for interconnected lines. Background Technology

[0002] In the construction of urban rail transit signaling systems, a test track is typically set up at the vehicle depot to conduct test runs and debugging of the signaling system. For interconnected lines, each line usually has its own independent test track.

[0003] When vehicle depots are co-located, the testing lines of multiple signaling manufacturers need to be considered, resulting in a waste of civil engineering resources. During the civil engineering design and construction process, a testing line needs to be reserved for each signaling manufacturer's vehicle depot, leading to a large scale of civil engineering work.

[0004] For interconnected non-co-located depots with two test tracks, each test track is only applicable to one line. Because there is a possibility that trains on this line may be parked or repaired in the parking and inspection depot of the interconnected line, during test operations, the trains on this line must first be shunted back to the depot on this line, and then shunted to the test track via a non-route to complete the test operations. Summary of the Invention

[0005] This invention provides a system and method for sharing a test track for interconnected lines, which addresses the shortcomings of existing technologies such as large civil engineering scale of test tracks, complex test operation processes, and high difficulty in operation plan preparation. It aims to reduce the civil engineering scale of test tracks, optimize test operation processes, and reduce the difficulty of operation plan preparation.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0036] The following is combined Figure 1 A system for sharing a test track for interconnecting lines according to the present invention includes:

[0037] The indoor signal equipment corresponding to each interconnection line is located on the same test line and is used by the corresponding interconnection line.

[0038] Signaling equipment is used to issue instructions and commands to relevant train operation and shunting personnel to ensure the safety of train operation and shunting work and improve railway throughput capacity.

[0039] Indoor signal equipment refers to signal equipment installed indoors in the test line room, such as lightning protection distribution cabinets and control consoles.

[0040] On the same test line, each interconnecting line is equipped with its own independent indoor signaling equipment. Two or more interconnecting lines share one test line.

[0041] During test runs, trains on each line communicate with the corresponding indoor signaling equipment by default to support normal train operation.

[0042] The first outdoor signal equipment corresponding to each interconnection line is located on the test line and is used by the corresponding interconnection line.

[0043] The first set of outdoor signal equipment refers to a portion of the signal equipment installed outdoors on the test track, such as signal lights and axle counters. On the same test track, this portion of outdoor signal equipment is independently installed for each interconnected line, such as... Figure 1 As shown by the solid line in the image.

[0044] The second outdoor signal equipment is located on the test line and is used by each interconnection line.

[0045] Secondary outdoor signaling equipment refers to another set of signaling equipment installed outdoors on the test track, such as passive transponders. Multiple interconnected lines may share this secondary outdoor signaling equipment, such as... Figure 1 As shown by the dashed line in the image.

[0046] LTE (Long Term Evolution) equipment, the LTE equipment being located on the test line, the LTE equipment providing vehicle-to-ground communication for each interconnecting line;

[0047] LTE equipment is interoperable. To avoid co-channel interference between LTE devices, indoor and trackside LTE equipment on the test track is shared by multiple interconnecting lines, such as... Figure 1 As shown by the dashed line in the image.

[0048] LTE devices connect to their respective LTE interfaces via fiber optic channels, and vehicle-mounted and ground equipment communicate using LTE devices by connecting to the LTE interfaces.

[0049] The interlocking equipment corresponding to each interconnection line is located on the test line and is used by the corresponding interconnection line.

[0050] Interlocking equipment is used to monitor whether trains are running, shunting operations are being carried out, or cars are occupied within a fixed section of track, ensuring the safety of train operation and shunting. Interlocking equipment is installed independently for each interconnected line, such as... Figure 1 As shown by the solid line in the image.

[0051] This embodiment achieves shared testing lines by independently setting up indoor signaling equipment, first outdoor signaling equipment, and interlocking equipment for multiple interconnected lines on the same test track, while sharing the second outdoor signaling equipment and LTE equipment among multiple interconnected lines. For interconnected lines co-located at vehicle depots, the shared testing line effectively reduces the scale of civil engineering and investment in rail transit construction. For interconnected lines not co-located at vehicle depots, the testing operation process is optimized, reducing the difficulty of operation plan preparation.

[0052] Based on the above embodiments, the indoor signaling equipment in this embodiment includes one or more of the following: ZC (Zone Controller), CI (Continuous Interlock), ATS (Automatic Train Supervision), DSU (Database Storage Unit), axle counter, combination cabinet, interface cabinet, lightning protection distribution cabinet, control console, and power supply panel.

[0053] Based on the above embodiments, the first outdoor signal device in this embodiment includes one or more of an active transponder, a counter, and a signal.

[0054] Based on the above embodiments, in this embodiment, the active transponder corresponding to each interconnection line is set independently and controlled by the indoor LEU (Lineside Electronic Unit) of each interconnection line;

[0055] The distance between the active transponders corresponding to any two interconnected lines is greater than a preset threshold.

[0056] For example, the distance between the active transponders corresponding to two interconnected lines is greater than 3m, thereby avoiding mutual interference between the active transponders.

[0057] The line number in the active transponder corresponding to each interconnection line is different from the main line number of each interconnection line.

[0058] By setting the line number in the active transponder to a different line number than the main line, the onboard ATP (Automatic Train Protection) can shield the active transponder messages of other interconnected lines.

[0059] Based on the above embodiments, in this embodiment, the axle counting head corresponding to each interconnected line is set independently and controlled by the indoor axle counting device of each interconnected line;

[0060] The axle counting heads with the same coordinates are respectively set on both sides of the track of the test line.

[0061] The coordinates of the axle counter head are the distance between the axle counter head and the starting point of the test track. If multiple interconnected lines correspond to axle counter heads with the same coordinates, they are placed on both sides of the test track to reduce mutual interference.

[0062] Based on the above embodiments, in this embodiment, the signal corresponding to each interconnection line is set up independently and controlled by the interlocking equipment corresponding to each interconnection line;

[0063] The signals with the same coordinates are respectively set on both sides of the track or on one side of the track of the test track and arranged side by side.

[0064] The coordinates of a signal are the distance from its installation location relative to the starting point of the test track. If multiple interconnected lines have the same coordinates for their corresponding signals, they are placed on both sides of the test track or side-by-side on one side of the track to reduce mutual interference.

[0065] Based on the above embodiments, in this embodiment, the signal light circuit of the signal machine is connected in series between the middle node and the front node of the relay, so that the signal light of the signal machine is in the off state when controlled by the depot or other lines. The relay is used to control whether the train agrees to test run.

[0066] To avoid simultaneous activation of signals and interference with train driver operations, a circuit is inserted between the middle and front nodes of the test track signal circuit into the signal light circuit of the train signal. This ensures that the signal on the corresponding track will only illuminate when the front node of the control relay is activated, confirming that the test is permitted. When the test track is under depot control or other line control, the train signal on the test track will remain off.

[0067] The interlocking device does not issue a fault alarm for the signal light when it detects that the signal light is in an off state under depot control or other line control.

[0068] To prevent the interlocking equipment on the test track from continuously alarming after detecting that the filament relay (DJ) of the train signal on the test track has fallen, the interlocking equipment on the test track will no longer alarm for filament faults when the test track is under depot control or other line control.

[0069] Based on the above embodiments, the second outdoor signal device in this embodiment includes a passive transponder and a sleep-wake transponder.

[0070] Passive transponders and sleep / wake-up transponders are shared by multiple interconnected lines, and these passive transponders and sleep / wake-up transponders are deployed according to unified requirements.

[0071] Based on the above embodiments, the interlocking equipment on the test track in this embodiment is used to allow the train route on the test track after collecting the train test approval information sent by the interlocking equipment of the depot.

[0072] Independent interlocking equipment is installed for each interconnected line on the test track. This interlocking equipment controls the train route conditions on each interconnected line. The test track interlocking equipment only allows trains on that interconnected line to proceed with the test track route after receiving confirmation of test approval from the depot interlocking system of the corresponding interconnected line.

[0073] The apparatus for a shared test track for interconnection lines provided by the present invention will be described below. The apparatus for a shared test track for interconnection lines described below can be referred to in correspondence with the method for a shared test track for interconnection lines described above.

[0074] like Figure 2 As shown, the method for sharing a test track for interconnected lines provided in this embodiment includes:

[0075] Step 201: Trains on each interconnected line communicate with the indoor signaling equipment and the first outdoor signaling equipment corresponding to each interconnected line;

[0076] Signaling equipment is used to issue instructions and commands to relevant train operation and shunting personnel to ensure the safety of train operation and shunting work and improve railway throughput capacity.

[0077] Indoor signal equipment refers to signal equipment installed indoors in the test line room, such as lightning protection distribution cabinets and control consoles.

[0078] On the same test line, each interconnecting line is equipped with its own independent indoor signaling equipment. Two or more interconnecting lines share one test line.

[0079] During test runs, trains on each line communicate with the corresponding indoor signaling equipment by default to support normal train operation.

[0080] The first type of outdoor signal equipment refers to a portion of the signal equipment installed outdoors on the test line, such as signal lights and axle counters. On the same test line, this portion of outdoor signal equipment is independently installed for each interconnected line.

[0081] Step 202: Trains on each interconnected line communicate with the second outdoor signaling equipment;

[0082] Secondary outdoor signaling equipment refers to another set of signaling equipment installed outdoors on the test track, such as passive transponders. Multiple interconnected lines share this secondary outdoor signaling equipment.

[0083] Step 203: Trains on each interconnected line communicate with ground equipment via LTE devices;

[0084] LTE equipment is interoperable. To avoid co-channel interference between LTE devices, indoor and trackside LTE equipment on the test track is shared by multiple interconnecting lines, such as... Figure 1 As shown by the dashed line in the image.

[0085] LTE devices connect to their respective LTE interfaces via fiber optic channels, and vehicle-mounted and ground equipment communicate using LTE devices by connecting to the LTE interfaces.

[0086] Step 204: Trains on each interconnected line are controlled via the interlocking equipment on each interconnected line;

[0087] Interlocking equipment is used to monitor whether there are trains running, shunting operations, or rolling stock occupancy within a fixed section of track, ensuring the safety of train operation and shunting. Interlocking equipment is installed independently for each interconnected line.

[0088] The indoor signaling equipment, the first outdoor signaling equipment, the second outdoor signaling equipment, the LTE equipment, and the interlocking equipment are located on the same test line.

[0089] This embodiment achieves shared testing lines by independently setting up indoor signaling equipment, first outdoor signaling equipment, and interlocking equipment for multiple interconnected lines on the same test track, while sharing the second outdoor signaling equipment and LTE equipment among multiple interconnected lines. For interconnected lines co-located at vehicle depots, the shared testing line effectively reduces the scale of civil engineering and investment in rail transit construction. For interconnected lines not co-located at vehicle depots, the testing operation process is optimized, reducing the difficulty of operation plan preparation.
