Rail vehicle emergency braking safety loop circuit and rail vehicle

Abstract

The invention provides a rail vehicle emergency braking safety loop circuit and a rail vehicle. The rail vehicle emergency braking safety loop circuit comprises a power supply, a negative terminal, aprimary safety line and a backup safety line arranged between the power supply and the negative terminal, the primary safety line penetrates through the head car and the tail car of the rail vehicle,the backup safety line penetrates through the head car and the tail car of the rail vehicle, and the primary safety line and the backup safety line are switched and connected through the first mode switch, so as to realize the emergency braking operation to the rail vehicle through the primary safety line or the backup safety line. According to the technical proposal provided by the invention, theredundancy, stability and reliability of the emergency brake safety loop circuit are effectively increased, the probability of vehicle rescue due to minor fault is reduced, the smoothness and smoothness of vehicle operation is improved, the cost of rescue and vehicle maintenance are reduced and prevented, and is beneficial to the traveling passengers and improves the efficiency of subway operation and passenger travel.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a rail vehicle emergency braking safety loop circuit and a rail vehicle. Background technique [0002] The subway vehicles in Kolkata, India are made of stainless steel vehicles, and 8 marshalling trains are used = DTC*MC1*TC*MC1*TC*MC1*MC2*DTC, and the power receiving method is DC750V third rail. The maximum design speed of the car is 80km / h, and the traction system adopts direct torque control. When braking, the electric brake is used first, and the electric energy is fed back to the grid. When the electric braking force is insufficient, the air brake will not exceed the sticking limit of the moving car. The lower average distribution is supplemented. The car brake can be divided into normal braking, full normal braking, handle emergency braking and emergency braking performed by the driver pressing the emergency brake button. [0003] Emergency braking is pure air brak...

Problems solved by technology

[0010] However, this circuit is only a single circuit. If one or more logic parts in the middle fail to work, normal driving will be caused. Even if multiple bypass buttons are operated to shield the fault point, it is not in compliance with safe driving regulations.

Then there is only one result at this time, and that is rescue. Once the rescue procedure is launched, it will not only affect the operation plan of the entire line, but also have to evacuate passengers, which seriously affects the travel efficiency of passengers.
