The embodiment of the present application provides a safety loop system and a rail vehicle, which relates to rail vehicle technology, and is used to overcome the difficulty in identifying a single vehicle failure through the safety loop after the existing vehicle has cut off the entire safety loop. low problem. The safety loop system includes: a first bypass switch, which is used to be installed in the head car; a second bypass switch, which is used to be respectively installed in at least one of the multiple compartments; the first bypass switch and the second bypass switch All the bypass switches have a bypass position; when the bypass positions of the first bypass switch and the second bypass switch are both in the off state, the first bypass switch and the second bypass switch are used to conduct the entire safety loop ; When the bypass position of the second bypass switch of the target car is switched to the closed state, the second bypass switch of the target car is used to connect the main train line and the train status line of the safety loop system, so that the local safety loop conduction.
Description
technical field [0001] The application relates to rail vehicle technology, in particular to a safety loop system and a rail vehicle. Background technique [0002] The EMU train is an important transportation link connecting various cities, and has gradually become the main means of transportation in the city. The EMU train mainly includes: a head car and multiple carriages; the front and rear ends of the EMU train are respectively provided with a head car, and the head car has a driver's cab; multiple cars are connected between the two head cars, and the cars are used to accommodate passengers or goods . [0003] In the related technology, the EMU train is provided with a safety loop, and the safety loop is used to monitor the fault during the operation of the EMU train; during the operation of the EMU train, when a fault occurs in a carriage, the safety of the entire train The loop will be disconnected, and the network system users of the EMU train will obtain the status ...
