Description

Technology Field

[0001] The present invention relates to an automatic block signaling (ABS) monitoring and AF track circuit remote control system, and more specifically, to an improved automatic block signaling (ABS) monitoring and AF track circuit remote control system that contributes to preventing not only train accidents on the track but also human casualties among workers performing track maintenance, because the automatic block signaling device, AF track circuit device, and railway track switch are simultaneously managed and controlled through the remote control system. Background Technology

[0002] Generally, for the safety of railway operations, speed conditions are controlled for each block section, taking into account the braking distance of the following train based on the position of the preceding train.

[0003] To this end, an Automatic Block System (ABS) is installed for each block section to automatically display the status of the corresponding block section on the block signal using color lights.

[0004] The automatic block control device of a specific block section communicates with the automatic block control device installed at the front, the automatic block control device installed at the rear, and the automatic block control device installed at the station to obtain status information of the front, and transmits its own status information to the rear or the station side.

[0005] At this time, the information transmitted between automatic block control devices includes track occupancy information, display information, and fault information, and this information is transmitted and received at a designated specific frequency.

[0006] In other words, previously, such information was transmitted and received between automatic block control devices via frequency communication, but frequency communication has the problem of reduced reliability due to external noise.

[0007] In addition, previously, there was no device to display signals related to preventing train entry during maintenance of equipment installed along the tracks in block sections, posing a risk of casualties.

[0008] Meanwhile, since track circuits utilize rails as electrical circuits, rail insulation methods were initially used. However, due to factors such as the increase in train speeds and issues regarding ride comfort, track circuits have evolved into non-insulated designs, and recently, non-insulated AF (Audio Frequency) track circuits are widely used.

[0009] The non-insulated method uses signal bonds to separate track circuits in order to distinguish adjacent tracks and circuits.

[0010] When Mini Bonds (MB) are installed across the two rails through which the train passes, a single block section is formed by the two rails and the two Mini Bonds crossing them, and a single track circuit is formed by the flow of signal current in this section.

[0011] However, due to the characteristics of the main line AF track circuit operating as an uninsulated type in urban railways, the occurrence of pre- and post-short circuits is inevitable. Furthermore, when simply applied, if pre- and post-short circuits occur in the uninsulated turnout AF track circuit on the turnout track, problems arise that impede the automatic operation of trains due to the related interlocking operation (locking).

[0012] In addition, maintenance is difficult, such as by adjusting the power output strength of the track circuit transmitter to minimize interference with adjacent track circuits and adjusting the sensitivity of the receiver to drop the track relay. Prior art literature
