Description

Technical Field

[0001] The utility model relates to the technical field of rail transit inspection tools, in particular to a subway signal AP antenna viewing device. Background Art

[0002] Subway signal AP antennas serve as communication antennas between subway trains and the ground control system. They act as a "talkie" between the trains and the ground control system, transmitting and receiving wireless signals. Their primary function is to monitor the train's real-time location and ensure safe and efficient operation. AP antennas are installed at regular intervals along the subway lines to ensure signal coverage throughout the entire network.

[0003] Currently, subway signal AP antennas require inspection and maintenance. During this inspection, the tightness of the antenna mounting screws must be checked. Inspections at elevated stations require application for an A1 inspection by an engineering vehicle or visual inspection using a telescope, which can be difficult to obtain approval for. Inspections at underground stations require manual work using ladders, which is inefficient and increases safety risks when working at heights (2-5 meters is considered a Level 1 inspection).

[0004] Therefore, trackside signal AP antenna maintenance work, which requires working at height, is limited. Without specialized tools, the inefficient methods of climbing ladders and visual inspections using engineering vehicles have been used. Furthermore, some overhead contact lines (non-contact rail) require even less space to work at height, making maintenance even more difficult.

[0005] Therefore, in order to address the deficiencies in the prior art, a subway signal AP antenna viewing device is provided. Utility Model Content
