All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, the present invention provides a method for combining group trains with inter-yard connections, the method comprising:
a train handling group train departure route short route sequence in a train yard I;
checking whether inter-yard contact conditions are met when the head car of the group train approaches to the short route of the end section of the first yard, and if so, opening a short route group signal of the end section of the first yard;
closing the end section short-route group signal (i.e., the group signal of the end section short-route annunciator) when the tail car of the group train cross-presses the annunciator for protecting the end section short-route;
and when the group train approaches the II yard, handling the train receiving short-circuit sequence of the II yard of the group train.
Described in detail below.
As shown in fig. 2, in this embodiment, a station has two yards, i.e., a yard I and a yard II, respectively, and a link between the yards I and II is referred to as an inter-yard link.
For the first yard, there are three annunciators on the track corresponding to the departure-to-pickup direction (i.e., from left to right in fig. 2), and it should be understood that the number of annunciators is not limited, and the three annunciators XII, V8, and V4 are respectively illustrated in this embodiment from left to right.
For the II yard, there are three annunciators on the track corresponding to the departure to pickup direction, and it should be understood that the number of annunciators is not limited, and this embodiment is exemplified by three annunciators, i.e., an incoming annunciator XL, an annunciator V3, and an annunciator XI, in order from left to right, on the track corresponding to the departure to pickup direction.
On the track in the direction from pick-up to departure (right to left in fig. 2), there are two annunciators (the number is not limited, and this embodiment is illustrated by two), which are annunciators SI and SL in this order from right to left, wherein SI is located between V3 and XI, and SL is located between V4 and XL.
The section between the traffic signal XII and the traffic signal V8 is the section 4DG, the section between the traffic signal V8 and the traffic signal V4 is the section 2DG, and the section between the traffic signal V4 and the traffic signal SL is the section 1BG. In addition, for the I-th yard, the entire system may be divided into two sections, i.e., a first section and a last section, for example, a section 4DG and a section 2DG may be used as the first section of the I-th yard, and a section 1BG may be used as the last section of the I-th yard. In this embodiment, the I-th yard is divided into two sections (i.e., a first section and a last section), and when the I-th yard is divided into the first section and the last section, the traffic signal V4 is located at the junction of the first section and the last section of the I-th yard.
The section between the incoming signal XL and the signal V3 is the section IAG, the section between the signal V3 and the signal SI is the section 1DG, and the section between the signal SI and the signal XI is the section IG.
The annunciators V8 and V4 are virtual annunciators, and the annunciators XII and SL are physical annunciators. The annunciators V3 are virtual annunciators, and other annunciators are physical annunciators.
For inter-field links, the section between the traffic signal SL and the inbound traffic signal XL is the section of the inter-field link (section I-IIG).
When the group train is adopted for launching, the launching group plan is Q001{ T001, T002}, when the launching condition is met, the group train Q001{ T001, T002} finishes grouping on the stock track, and launches in the form of the group train, namely, the head train in the group train is T001, and the tail train is T002.
In this embodiment, the key relay includes:
zcj (look-up relay): the device is sucked up at ordinary times, and falls down after the approach is locked when shunting or train approach is arranged to the inter-field tie line; the last section of the approach is sucked up when it is unlocked. When the neighboring field is arranged to the own field, it is required to check the sucking up.
Zj (terminal relay): when the vehicle falls down at ordinary times and the shunting route is arranged to the inter-field connecting line, the route is sucked up after being locked; the last section of the approach falls after unlocking.
Gjj (stock check relay): when the train is dropped at ordinary times and the route is arranged to the inter-field tie line, the route is sucked up after being locked; the train falls down after being pressed into a first section inside the annunciator; the signal is closed, the access is locked completely, and any section in the access occupies GJJ and keeps falling.
After the completion of the grouping, CTC (Centralized Traffic Control, dispatch centralized system) handles the short route sequence { route XII-V8, route V8-V4, route V4-SL }, in which ZCJ of the ith yard can be driven to drop and GJJ is sucked up by CBI (Computer BasedInterlocking, computer interlock) after the short route of the section where V4-SL is located (section IBG) as shown in fig. 3. The precondition for the short-circuit locking of the section where V4-SL is that the section where XII-V4 is located (the first section of the I-th yard) is short-circuit locked.
Before handling the approach of the head car of the group train in the first section of the I yard, check whether the group train has departure conditions, specifically comprising:
the GCC (Group Control Center ) judges whether the short route sequence of the I-th parking lot locked by CBI control is consistent with the operation plan of the head car T001, and judges whether the short route of the I-th parking lot (the whole I-th parking lot and the II-th parking lot are all large short routes, one large short route is divided into a plurality of short routes, and the short route refers to the large short route of the whole I-th parking lot) is idle or not through the GCC;
when the short-circuit sequence of the locked ith yard is consistent with the short-circuit operation plan of the head truck T001, and in the operation plan of the short-circuit of the ith yard, if the short-circuit of the ith yard is idle, the GCC notifies the CBI of a logic open signal condition of the short-circuit (i.e., the GCC sends an enable signal of "signal enable open" of the first section of the ith yard to the CBI), the CBI receives the enable signal of "signal enable open" sent by the GCC, checks that other signal open conditions (e.g., the opening of the group signal of XII needs to check that the first section of the ith yard is idle) are satisfied, and the CBI opens the group signal of XII and the group signal of V8.
After both the group signal of XII and the group signal of V8 are opened, the group train already has a departure condition, so that the short route of the group train in the first section of the I-th yard can be handled, and the first train T001 can start to make the short route in the first section of the I-th yard.
As shown in fig. 4, when the tail car T002 completely enters the first zone of the ith yard, the CBI receives the enable signal of "signal enable open" of the last zone of the ith yard sent by the GCC, and checks whether the ith yard meets the inter-yard contact condition and whether the ZCJ of the II yard meets the pick-up, if both meet, the group signal of V4 (i.e. the signal corresponding to the annunciator V4) in the ith yard is opened, where the inter-yard contact condition is:
the inter-yard interconnecting line between the first yard and the second yard is idle, and the second yard does not take a departure.
While checking that the ZCJ of the II yard is sucked up and that the inter-yard tie line between the I yard and the II yard is free, the CBI checks that other signal opening conditions (e.g., conditions such as the corresponding zone is free) are satisfied and that the CBI opens the group signal (short-way signal of the last zone) of V4.
As shown in fig. 5, after the group signal of V4 is opened, when the head car T001 crosses the traffic signal V4 (i.e., when the head car T001 starts to enter the last zone of the ith yard), at this time, the CBI controls the ZCJ to drop (the CBI controls the II yard to prohibit departure and only connect the yard through the inter-yard connection circuit), the GCC continues to check whether the zones I-IIG (the zones where inter-yard connection lines are located) are idle, and if so, at this time, the movement authorization for the head car T001 is updated to the arrival traffic signal XL of the II yard.
As shown in fig. 6, after the CBI detects that the group train sequentially enters the last short route of the ith yard, that is, after the head train of the group train enters the last section (section 1 BG) of the ith yard, before the tail train T002 crosses the voltage signal V4, according to the "signal permission open" condition of the section 1BG, the interior of the route of the last section of the ith yard is not checked, and the group signal of V4 remains open.
As shown in fig. 7, at the time of the tail car T002 crossing the traffic signal V4, the group train can handle the short route at the II yard, wherein the short route sequence { route XL-V3, route V3-SI } of XL to XI needs to be handled before the group train handles the short route at the II yard. Judging whether the short-circuit sequence of the CBI locking yard II is consistent with the short-circuit operation plan of the head car T001 through GCC, and judging whether the short-circuit of the yard II is locked and idle in the short-circuit operation plan of the yard II through GCC.
When the GCC determines that the short-circuit sequence of the II yard locked by the CBI is consistent with the short-circuit operation plan of the head car T001 and determines that the short-circuit of the II yard is locked and idle in the operation plan of the short-circuit of the II yard, the GCC notifies the CBI of the condition that the CBI has the short-circuit logic open signal (i.e., the GCC transmits an enable signal of "signal enable open" of the head section of the II yard to the CBI). When the CBI receives the first section "signal enable open" enable signal of the II yard transmitted by the GCC, it checks that other signal open conditions (for example, the open need check section IAG of the XL group signal is idle, the open need check 1DG of the V3 group signal is idle) are satisfied, and the CBI opens the group signals of XL and V3.
The group train handles the short way of the yard II comprising:
upon the tail car T002 crossing the voltage annunciator V4, the GCC informs the CBI to turn off the group signal of V4. CBI off signal (group signal of V4), CBI drives GJJ of inter-field association down.
As shown in fig. 8, when all trains of the group trains enter the inter-yard interconnecting line, the ZCJ of the ith yard is controlled to suck so as to lock the short route of the ith yard, i.e. the ith yard is idle at this time, other group trains can be handled continuously, and the short route sequence of the ith yard is performed.
As shown in fig. 9, after the head car T001 enters the first section (section 1 AG) of the II yard, the CBI checks that the group train sequentially enters the first short route (i.e., the short route of section 1 AG) of the II yard, and the group signal of the incoming signal XL is controlled to remain open without checking that the inside of the route (inside of the incoming signal XL) is idle according to the "signal permission open" condition of section 1 AG.
As shown in fig. 10, when the tail car T002 straddles the inbound signal XL of the II yard, the GCC sends the tail car straddling pressure of the group train to the CBI, which controls the group signal of the inbound signal XL to be turned off.
As shown in fig. 11, after the group train has completely entered the interior of the ingress traffic signal XL (the first section of the II yard, section IAG), the inter-yard tie-lines are cleared.
As shown in fig. 12, after tail car T002 straddles the head section of the II yard, the head section of the II yard is unlocked.
As shown in fig. 13, after the first section of the II yard is unlocked, the group train completely enters the last section of the II yard and parks, i.e., the group train completely enters the track park at the last section.
In addition, in this embodiment, the group train handles the short route of the II yard further includes:
when the head train of the group train enters the inter-field interconnecting line, the CBI controls the ZJ and GJJ of the inter-field interconnecting line to be sucked up;
in another aspect, the present invention also provides a system for associating a group train with a farm, the system comprising:
