Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a portable simulated switch. Background Technology

[0002] With the rapid development of railway systems, the tracks in these systems are crisscrossed, making turnout switching a routine operation. To achieve accurate turnout switching, both a signal equipment room and a switch machine are indispensable in the railway system. The signal equipment room centrally controls the railway ground signals and issues turnout switching operation commands; the switch machine, based on these commands, drives the rails to complete the turnout switching.

[0003] To ensure the accuracy of turnout switching, railway signaling system interlocking tests are required for the signal equipment room and switch machines. The conventional practice is to conduct signal consistency interlocking tests only after both the signal equipment room and switch machines are installed and the control cables between them are connected. However, in actual construction, signaling system construction is often hampered by the lack of switch machine installation facilities at the construction site. This frequently results in situations where the signal equipment room is completed, but the switch machines cannot be installed immediately, preventing signal interlocking tests and delaying signal commissioning progress.
