Description

Active signal transponder and large number switch signal signal control system and method

The present application claims the priority of the Chinese Patent Application No. 201711107344.2 filed on November 10, 2017, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present disclosure relates to the field of rail transit, and more particularly to a signal control system and a control method for a train control center utilizing an existing active transponder and a large number switch message.

Background technique

Railway interchange channels are classified according to the number of 6, 7, 8, 9, 12, 18 and large numbers (such as No. 30, 38, and 42), among which No. 6, No. 7, and No. 8 are mainly used for industrial and mining enterprises. Lines or freight yards; there are 9th, 12th, and 18th single lanes commonly used for railway trunk line operations, and the No. 18 roadway is the main passenger line; the large number roadway is mainly used to require the side line to pass the higher speed tie line.

For the independently set large number switch responder group, its position is clearly required in the relevant specifications: generally set outside the large number switch, send the U2S occlusion partition entrance 200 ± 0.5m, as shown in Figure 1. When the U2S occlusion partition entry does not have the setting condition, it can be set in the U2S or UUS partition farther away from the protection big number switch, as shown in Figure 2.

1) Pick up the big number switch transponder group

As shown in FIG. 3, the 1DG is a large number switch. When the X-SHF side-by-side approach is arranged and the large number switch responder message transmission condition is met, the large number switch active transponder sends the CTCS-4 packet. The control train passes the large number switch at the "V_TURNOUT" speed described in the CTCS-4 package.

2) Departure number switch set

As shown in Fig. 4, the 2DG is a large number switch. When the SIV-XF is arranged in the lateral direction and meets the condition of the big number switch transponder, the large number switch active transponder sends the CTCS-4 packet to control. The train passes the large number switch at the "V_TURNOUT" speed described in the CTCS-4 package.

The layout of the large number switch requires that "the general setting is 200±0.5m from the outside of the large number switch and the U2S occlusion partition is entered," meaning that at least two blocked partitions are required. However, for some special scenarios, such as the case where the interval is too short, the large number switch responder group cannot be set separately according to the specification. Even if the large number switch responder group is separately arranged, the CTCS-4 package cannot meet the speed increase requirement. The distance cannot be passed by the train at the "V_TURNOUT" speed described in the CTCS-4 package.

Summary of the invention

In view of this, the present disclosure provides a signal control system and a control method for a column control center using an existing active transponder and a large number switch message, and does not need to separately arrange a large number transponder, and can solve the problem that the interval is too short to be satisfied. The problem of speeding up the required distance and reducing the arrangement of the transponder simplifies the system and reduces costs.

Detailed ways

The present disclosure is described below based on the embodiments, but the present disclosure is not limited to only these embodiments.

The present disclosure provides a signal control system that utilizes an existing active transponder to transmit a large number switch message, including an existing active transponder for transmitting a large number switch acknowledgement message, and a train onboard ATP device, the present disclosure The large number switch set is not separately arranged, and the active transponder is implemented as an active/transponder active transponder, a relay active transponder or a non-wired station active transponder, which doubles as a large number switch. The function is to use the existing in/out active transponder, relay active transponder or non-distribution station active transponder to send large number switch transponder messages to realize the switch when the train passes the large number switch in the lateral direction. speed.

The present disclosure also provides a signal control method for utilizing an existing active transponder and a large number switch message, and the existing in/out active transponder, relay active transponder or unmatched through the column control center The line station active transponder is configured to concurrently generate a large channel transponder message and further configure the correspondence between the pick-up path and the existing active transponder that transmits the large-channel switcher message.

Then, when the large number switch is turned on, both the active transponder and the train ATP device send a large-sized switch transponder message; the train-mounted ATP device receives the large-number switch responder message and processes it to realize the train speed control. .

Specifically, as a first embodiment of the present disclosure, as shown in FIG. 3, when the lateral starting approach of the X-SHF is arranged and the large number switch responder message transmission condition is met, it is different from the prior art alone. Set the pick-up big number transponder group to realize the train ballast speed control. The present disclosure controls the train to pass the large number at the "V_TURNOUT" speed described in the CTCS-4 package by using the inbound port active transponder and transmitting the CTCS-4 packet. Turns.

As another embodiment of the present disclosure, as shown in FIG. 4, when the lateral starting approach of the SIV-XF is arranged and the large number switch responder message transmission condition is met, the large number of the pick-up is separately set from the prior art. The transponder group implements train track speed control. The present disclosure controls the train to pass the large number switch at the "V_TURNOUT" speed described in the CTCS-4 package by means of both the ingress port active transponder and the transmit CTCS-4 packet.

As another embodiment of the present disclosure, as shown in FIG. 5, for the case where the train line is "bent in and out", there are a plurality of pick-up paths and a plurality of large number switches (1, 3, 5 in the figure). 7), this embodiment uses an existing in/out station active transponder to transmit a large number switch responder message. The train control center configures the correspondence between the pick-up approach and the existing active transponder that sends the large-scale switcher message.

For the same big number switch, if there are multiple pick-up routes ahead, you can select different active transponders and send large number switch responders according to different routes. A plurality of pick-up routes are one of the conditions for checking the big number switch in an "or" manner, and a large number of switch responder messages can be sent as long as one approach is satisfied.

As a specific embodiment of the present disclosure, when an incoming route is taken, an existing active transponder and a large number switch responder message are selected on the way, for example, X->XIII->XL1->SHF When entering the road, the X inbound port transponder has the function of transmitting the large number switch transponder message of the switch 1; when handling the XIII->XL1->SHF approach, the XIII exit port transponder has the large transmission channel 1 The function of the number switcher message. For example, for the large number switch 1 in Figure 5, the large number switch responder message of the route X->XIII->SHF is sent by the X-station mobile station active transponder; the large number of the route XF->XIV->SHF The switch responder message is sent by the XF multi-way ingress active transponder.

Correspondingly, if there are multiple large number switches in the same way, since one way only supports sending a big number switch transponder, the way selects both an in/out active transponder, a relay active transponder or When there is no wiring station active transponder and a large number switch transponder message, it can only be sent to one of the big number switches. However, different large-number switch responder messages can be sent by statically configuring the train center TCC. For example, in Figure 5, X->XIII and X->XII are all based on the X-incoming signal. The two different approaches can support: when handling the route X->XIII->SHF, the active transponder of the X-station station can send the large number switcher message of the switch 1; When >XII->SH, the active transponder of the travel station under X can send the large number switch transponder message of switch 5.

All of the above are examples of the functions of the existing in/out active transponders as the large number switch transponders, and those skilled in the art can easily expand to existing relay active transponders or non-wired station active transponders. The implementation of the number switcher function.

In summary, the present disclosure utilizes both an inbound/outbound active transponder, a relay active transponder, or a non-wired station active transponder to serve as a large number switch, without affecting its transmission route information and speed limit information. Under the premise of the function message, the function of the big number switch transponder message is also issued, and there is no influence on the driving efficiency.

The above description is only a preferred embodiment of the present disclosure, and is not intended to limit the disclosure, and various changes and modifications may be made in the present disclosure. Any modifications, equivalents, improvements, etc. made within the spirit and scope of the present disclosure are intended to be included within the scope of the present disclosure.
