Motor train unit safety loop bypass system

Abstract

The invention relates to the technical field of motor train unit safety, in particular to a motor train unit safety loop bypass system which aims at solving the problems that after an existing safetyloop is abnormally powered off, a fault point cannot be quickly found, a motor train unit stays in an operation line for a long time, and the operation order is seriously affected. The motor train unit safety loop bypass system comprises a main control train safety loop control circuit and a bypass system, and the bypass system comprises a first bypass switch and a second bypass switch; one end ofthe first bypass switch is connected with an alert device in the main control train safety loop control circuit, and the other end of the first bypass switch is connected with one end of an ATP control contact, connected in series in a safety loop, in the main control train safety loop control circuit; and one end of the second bypass switch is connected with the other end of the ATP control contact, connected in series in the safety loop, in the main control train safety loop control circuit. By closing the first bypass switch and / or the second bypass switch, emergency closing in a fault ofthe safety loop is achieved, and the system avoids unnecessary losses of passengers caused by train delay.

Description

technical field [0001] The invention relates to the technical field of EMU safety, in particular to an EMU safety loop bypass system. Background technique [0002] In order to ensure the safe operation of the EMU, the EMU is equipped with a safety loop that can trigger emergency braking. In an emergency, the safety loop loses power and triggers the emergency brake quickly, which can ensure that the EMU stops in the shortest time to ensure safety. When the EMU is in operation, the failure of the relays of each node in the safety loop and the connection of the line may cause the abnormal power loss of the safety loop, triggering the emergency braking of the train set, which cannot be normally relieved, resulting in a delay in the operation of the train set. [0003] The electrical components and wires of the existing EMU safety loop run through the entire train, and there are many nodes. After the safety loop loses power abnormally, it is impossible to quickly find the fault p...
