Abstract

The invention discloses a safety loop system, which comprises a power supply adjusting unit, fault detection units and a safety protection unit. The power supply adjusting unit is used for supplying power to the fault detection units and the safety protection unit; the fault detection units are connected to the safety protection unit in parallel; the number of the fault detection units is multiple, the fault detection units are connected in parallel and distributed in different carriages respectively, each fault detection unit comprises a fault detection switch, which is used for switching onelectric connection between two ends of the fault detection switch when a system fault signal is detected. The invention further relates to a rail train. The invention has the advantages that: the fault detection unit of each carriage and the safety protection unit are connected in parallel to form a safety loop, safe operation of the rail train is ensured, the structure is simple, oxidation caused by actions of the fault detection switches can be avoided, the reliability is high, and low-carbon and environment-friendly effects are achieved.

Description

technical field [0001] The invention relates to the technical field of rail trains, in particular to a safety loop system and rail trains. Background technique [0002] The purpose of designing a safety loop system on rail trains is to use it in door control, pyrotechnic control, axle alarm control and brake control systems when the door is not closed properly, fire occurs, the axle is overheated, and the brake is not good. In the event of faults such as train separation or train separation, the train driver can obtain the operating status of each system in a timely and effective manner. According to the failure situation, the rail train automatically applies emergency braking to ensure the safety of the rail train. [0003] At present, there are safety loops installed in rail trains, which are composed of multiple devices connected electrically to form a system. The safety design is guided by the failure of a single device. , prompt the train driver and take corresponding...
