Abstract

The invention discloses a warning device for electric passenger train maintenance operation and a warning method thereof. The warning device comprises a first unit and a second unit. The first unit comprises a first optoelectronic switch, a first PLC, a wireless transmitting module, a first voice broadcasting module and a first loudspeaker. The second unit comprises a rail checking lock, a rail checking key matched with the rail checking lock, a second photoelectric switch, a second PLC, a wireless receiving module, a nixie tube, a first working state indicating lamp, a second working state indicating lamp, a second voice broadcasting module and a second loudspeaker. According to the warning device and the warning method, the safety accident of contact net short-circuit generated when a grounding rod is hung is effectively avoided, the equipment loss and personnel injury caused by the contact net short-circuit are avoided, and all-directional reminding and protection are conducted foroperators.

Description

technical field [0001] The invention relates to the field of electric passenger train maintenance operations, in particular to a warning device and a warning method for electric passenger train maintenance operations. Background technique [0002] With the rapid development of the subway in recent years, it has basically formed a network. However, due to the early construction, there are many basic equipments that are aging and incomplete, which cannot meet the current requirements for vehicle maintenance. In order to ensure the safety of people's travel, many equipments need to be upgraded and replaced. [0003] In the maintenance operation of the original electric passenger train, there is no hardware for warning and monitoring in each link. The specific process is: register at the Depot Control Center (DCC) and borrow the key of the power-off box with the number of power-off channels. Open the box and disconnect the switch knife, hang the prohibition sign after the power...
