A safety circuit capable of flexibly grouping vehicles and the flexible grouping vehicle

Abstract

The invention discloses a safety circuit with a flexible vehicle marshaling function and a vehicle capable of being flexibly marshaled. The safety circuit comprises an electrical vehicle hook, a first selective switch set, a second selective switch set, a first normally-closed switch and a second normally-closed switch, wherein the first normally-closed switch and the second normally-closed switch are connected in series to form a brake branch. The first selective switch set comprises a first normally-closed contact pair, a second normally-closed contact pair and a first normally-open contact pair. The second selective switch set comprises a second normally-open contact pair and a third normally-closed contact pair. The electrical vehicle hook comprises a first contact, a second contact, a third contact, a fourth contact, a fifth contact, a sixth contact, a seventh contact, an eighth contact, a ninth contact, a tenth contact, a fourth normally-closed contact pair and a fifth normally-closed contact pair, wherein the first contact, the second contact, the third contact, the fourth contact and the fifth contact are located on one side of the single-joint vehicle, and the sixth contact, the seventh contact, the eighth contact, the ninth contact and the tenth contact are located on the other side of the single-joint vehicle. The safety circuit is simple in structure and easy to operate, the non-fault rate of a train is increased, the control capacity of the train is improved, the manual operation process is shortened, time is saved, and the reliability and maintainability of a system are improved.

Description

technical field [0001] The invention belongs to the field of urban rail vehicles, and in particular relates to a safety circuit of vehicles that can be flexibly organized and the vehicles that can be flexibly organized. Background technique [0002] Flexible marshalling vehicles refer to trains that can operate independently with a single vehicle, and can also run multiple vehicles together as needed, including APM (Automated People Mover Systems), light rail vehicles, etc. [0003] In the train safety circuit, if the brake control unit receives a high level, the train will not produce emergency braking; if the brake control unit receives a low level, the train will produce emergency braking. For vehicles that can be flexibly marshalled, the safety loop of the train will change after marshalling and unmarshalling, that is, if a single car runs as a unit, in order to form a vehicle safety circuit, both ends of the car must be closed separately; if two or more cars Link, in o...

Problems solved by technology

[0005] Due to the high failure rate of the relay itself, and the occurrence of its failure is occasional and non-repetitive, in the case of a large number of relays, the failure rate will increase significantly, affecting the reliability of vehicle operation
