[0002] The use of iron shoes and manual brake fasteners is an important means and safety measure for the locomotive and vehicle maintenance departments to prevent locomotives and vehicles from slipping. During operation, iron shoes are placed on one or two rails at the front and rear ends of the locomotive to prevent the wheels from turning forward and play a braking role. The traditional anti-slip iron shoe deployment operation is mainly operated manually, with low efficiency and supervision loopholes. Due to the large number of iron shoes, operators are prone to confusion and forget the location of the iron shoes after placing too many. In addition, the duty room can only supervise the iron shoes through verbal communication by the personnel in charge, and direct supervision cannot be achieved. In addition, when the iron shoes are not deployed in place, such as anti-slip failure, mistaken withdrawal, omission, loss, theft, and driving the shoe, the operator cannot discover it in time. Operators need to frequently cross the track during on-site inspections, which poses a safety hazard.
