Four-wire system two-wire system direction circuit combined transition control system
Technical Field
The invention relates to the technical field of railway system control, in particular to a four-wire system two-wire system direction circuit combined transition control system.
Background
In the double-line bidirectional automatic blocking section, the trains generally run according to normal uplink and downlink tracking, and the trains on the upper side and the lower side are not interfered with each other. However, in special cases, the train needs to run reversely, such as the uplink fault or construction in the block section, and the uplink train needs to run temporarily in the downlink, and then the direction changing circuit needs to change the running direction of the downlink to determine the running direction of the train. The task of determining the car receiving and the car sending, converting the sending and receiving equipment of the section, and enabling the traffic signal in a specified direction to turn off the light and changing the running direction is completed by a direction circuit.
Two-wire system direction circuits and four-wire system direction circuits which are commonly used in domestic railways are respectively provided with a set of direction changing circuit corresponding to each train receiving direction and train sending direction of a station, and the greatest difference between the two direction circuits is that the two direction circuits are in external connection with each other between two adjacent stations, wherein one direction circuit is composed of two external lines and one direction circuit is composed of four external lines. The corresponding circuit components are also different, so that two adjacent stations can only use the directional circuit of the same system.
The two-wire system and four-wire system direction circuit is combined with transition and is first used in the self-closing reconstruction construction of the Beijing Guangdong line horizontal cattail section. The existing direction-changing circuit is in a two-wire system, the newly-set direction circuit is in a four-wire system, when the existing direction-changing circuit is opened in a segmented mode, an opening station is in the newly-set four-wire system direction circuit, an adjacent station is in the two-wire system direction circuit, the adjacent station needs to be subjected to one-edition transition interlocking software to be transited and opened, and the four-wire system direction circuit and the opening station are enabled to unify the circuit system, so that development software and transition cost are increased.
Disclosure of Invention
Aiming at the technical problems in the prior art, the invention provides a four-wire system two-wire system direction circuit combined transition control system to solve the problem that transition of the four-wire system direction circuit needs to be realized through transition interlocking software as a temporary transition cost is overlarge.
The technical scheme for solving the technical problems is as follows: a four-wire system two-wire system direction circuit combined transition control system comprises a new open station line and a plurality of adjacent station lines which are distributed in sequence along the direction of the open station line; the newly opened station line is a newly opened four-wire system direction circuit along the direction of the adjacent station lines, and the original two-wire system direction circuit is arranged among the adjacent station lines; the interval supervision loop of the four-wire system direction circuit is combined with the two outer wire loops of the two-wire system direction circuit.
On the basis of the technical scheme, the invention can be improved as follows.
Further, the four-wire system direction circuit consists of four external wires, wherein two external wires are direction control loops, and the other two external wires are interval supervision loops; the two-wire directional circuit combines the directional control loop and the interval supervision loop into a loop.
Further, the operation direction relay FJ1 and the operation direction relay FJ2 of the two-wire directional circuit are short-circuited by a lead wire.
Further, the four-wire direction change relay GFJ of the four-wire direction circuit is turned off.
Further, when an adjacent station line is modified to newly open the four-wire directional circuit, the adjacent station line serves as a new newly opened station line.
The beneficial effects of the invention are as follows: the four-wire system two-wire system direction circuit combined transition control system combines the interval supervision loop of the four-wire system direction circuit of the newly opened station line with the two-outer line loop of the two-wire system direction circuit, thereby supervising whether the supervision interval is occupied by a train or not, and simultaneously the circuit does not influence the function of transmitting trains between two adjacent stations. The whole transition combining method effectively saves the cost of transition software and ensures the normal transportation of trains among all stations.

Detailed Description
The principles and features of the present invention are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the invention and are not to be construed as limiting the scope of the invention.
It should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, unless otherwise specifically indicated and defined. The specific meaning of such terms in this patent will be understood by those of ordinary skill in the art as the case may be.
In a double-line bidirectional automatic blocking section, in order to determine the running direction of a train, the running direction of the train needs to be changed by matching with a direction circuit, and the following analysis is performed on the running of the train:
assuming that the first station is a receiving station and the second station is a transmitting station, the line is a forward line. When the interval is idle, the arrow of the first station receiving direction is yellow, and the arrow of the second station departure direction is green, as shown in fig. 1.
If the first station handles the change operation paying-off to the second station, the first station changes the direction arrow of the departure station to be green and the second station changes the direction arrow of the receiving station to be yellow after the change of the operation direction is completed in the interval of the first station and the second station, and the method is particularly shown in fig. 2.
The direction circuit is generally a four-wire system direction circuit or a two-wire system direction circuit, the four-wire system direction circuit is composed of four outer wires, two core outer wires are direction control loops, and the other two cores are interval supervision loops; the two-wire system direction circuit combines the direction control circuit and the interval supervision circuit into a circuit, only two-core external wires are used, a four-wire system break relay is omitted, the function of the control relay is added, fig. 3 and fig. 4 are schematic diagrams of the two-wire system direction circuit and the four-wire system direction circuit respectively, and corresponding code names of the two-wire system direction circuit and the four-wire system direction circuit can be seen from fig. 9.
Summarizing is generally carried out in the line construction transformation process, so that in order to unify the circuit systems of adjacent stations, transition is required to be carried out through transition interlocking software, and development software and transition cost are increased. For example, as shown in fig. 5 below, the cross-gap bridge is opened to the station section, the station is opened only to the half-edge section of the cross-gap bridge, and the direction circuit in the section must be used as a four-wire direction circuit with the direction circuit of the cross-gap bridge station; the tranquilization station is opened again next time to the officinal pond post, and the two-wire directional circuit is still needed for the half throat.
In order to solve the problem that the interlocking software must be replaced when the same station has both a four-wire system direction circuit and a two-wire system direction circuit, the invention provides a four-wire system two-wire system direction circuit combined transition control system to solve the problem.
As shown in fig. 6, 7 and 8, the four-wire two-wire directional circuit combined transition control system designed by the invention comprises a new open station line and a plurality of adjacent station lines distributed in sequence along the direction of the open station line; the new open station line is a new open four-wire system direction circuit along the direction of the adjacent station lines, and the original two-wire system direction circuit is arranged among the adjacent station lines. The circuit principles of the four-wire system direction circuit and the two-wire system circuit are respectively shown in fig. 3 and 4, the four-wire system direction circuit consists of four outer wires, two core outer wires are direction control loops, and the other two cores are interval supervision loops. The two-wire system direction circuit is two outer wire circuits which are used by the direction control circuit and the interval supervision circuit.
In this embodiment, taking the transformation of the transverse channel bridge station line as an example, the transverse channel bridge station line is used as a new open station line to adopt a four-wire system direction circuit, and the station post station are used as adjacent station lines to be two-wire system direction circuits which are not transformed. In order to ensure the normal operation of the transverse ditch bridge station and the station line, the section supervision loop of the four-wire system direction circuit of the newly opened station line is combined with the two outer wire loops of the two-wire system direction circuit of the station in order to supervise whether the supervision section is occupied by a train or not, and meanwhile, the function of indirectly sending the train between two adjacent stations is not influenced by the circuit.
In addition, when the horizontal channel bridge station and the station are combined and transited, in order to avoid the influence of the change of the direction circuit between the station and the station on the running of the direction circuit between the station and the station by changing the wiring, the running direction relay FJ1 and the running direction relay FJ2 of the two-wire system direction circuit of the station need to be short-circuited by the lead wire, so that the function of changing the running direction of the two-wire system direction circuit is temporarily disabled, and the normal running of the train between the station and the station along the horizontal channel bridge is ensured.
After the task of transporting the train between the transverse ditch bridge station and the corning station is finished, the short circuit of the running direction relay FJ1 and the running direction relay FJ2 is relieved, so that the communication of a two-wire system direction circuit between the corning station and the official pond post is recovered, and the normal transportation of the train between the corning station and the official pond post is ensured.
Because the four-wire directional circuit described above, in combination with the two-wire directional circuit, temporarily fails the function of changing direction between the two stations, it is necessary to turn off the direction-changing relay GFJ of the newly opened station line four-wire directional circuit. After the four-wire system direction circuit of the next station is transformed, the new transformation station is used as a new opening station line to be directly connected with the station line transformed by the four-wire system direction circuit of the previous station through the four-wire system direction circuit, and at the moment, a running direction changing relay GFJ of the four-wire system direction circuit of the previous station can be opened to recover the function of changing the running direction. When the new open station line and the subsequent unmodified adjacent station line need to be combined temporarily to convey trains, the method of combining the four-wire system direction circuit with the transitional two-wire system direction circuit can be adopted, and the method can be adopted until all the station lines are modified into the four-wire system direction circuit, so that the cost of transition software is effectively saved by the whole combined transition method, and the normal conveying of trains among all stations is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
