Multi-system rail vehicle fireless returning device

Abstract

A multi-system rail vehicle fireless returning device specifically comprises a train pipe connector, a gas-electricity converting module, an AD converting module, a signal output module, a signal processing module, a wireless feedback module, a man-machine interface module and an electric connector. The train pipe connector is used for being connected with an external returning train to collect train air pressure. The electric connector is used for being connected with a brake control device of a returned rail vehicle to transmit braking instructions. The multi-system rail vehicle fireless returning device is especially suitable for delivery of subways or urban rail vehicles of various braking systems such as Knoll, Faiveley and Nabtesco, gas pressure can be collected accurately, and a wireless feedback function is achieved.

Description

technical field [0001] The invention relates to a non-fire return for rail vehicles, which can be applied to the delivery and transportation of subway or urban rail vehicles with various braking systems such as Knorr-Bremse, Faiveley, and Nabtesco, that is, multi-system rail vehicles without fire loopback device. Background technique [0002] With the accelerated development of urbanization, the development of urban rail transit system is getting more and more attention. The urban rail transit vehicles usually refer to subways, light rails and monorails. After the dynamic experiment and dynamic experiment, the vehicle needs to be delivered to the subway user for on-site test and application; in practice, the transportation process of the subway and urban rail vehicle from the manufacturing plant location to the actual operating city after the completion of the manufacturing is called return. At present, the return methods of subway vehicles in China mainly include air trans...

AI Technical Summary

Problems solved by technology

At present, the return methods of subway vehicles in China mainly include air transportation, sea transportation, road transportation, and railway transportation. Among them, the air transportation method is fast but costly, and is mostly used in international emergency transportation; although the sea transportation method is low in cost but faster. It is slow and requires ports, and is generally used for transportation between overseas port cities; road transportation was once the mainstream method for the return of subway vehicles in China, but road transportation needs to disassemble the vehicles and dismantle the vehicle bogies and car bodies, which is not only slow , loading and unloading is difficult, and prone to accidents, which has a great impact on the normal operation of the road, has gradually withdrawn from the long-distance transportation of subway vehicles; railway transportation generally adopts the non-fire return method, that is, the subway vehicles themselves do not use power, and are only used as ordinary trains and vehicles. Mainline train marshalling, a transportation method that participates in the braking of mainline trains; since the subway vehicles do not need to be disassembled when there is no fire return, they can be transported as a whole and the transportation speed is fast, and it also saves disassembly, assembly, loading and unloading, etc. Although it is Currently the most economical mode of transportation, but because there is a large difference in the braking method between subway vehicles and main-line railway vehicles, a set of fire-free return device is required for railway transportation return to solve the problem of subway and other rail vehicles and main-line railway vehicles. Brake relief, synchronization matching and other issues

In recent years, my country's subway vehicle manufacturing has shown explosive growth, and subway vehicles are also diversifying daily, but the research and development of non-fire return devices is far behind the needs; the non-fire return devices currently seen are mainly for individual, specific The braking system of the conventional brake system has poor versatility; for example, a fire-free return device for a hydraulic transmission locomotive disclosed in Chinese patent 2012101619077 is only applicable to a hydraulic transmission locomotive with a three-axle bogie; in addition, there are also existing Fire-free return devices specific to the three major braking systems of Knorr-Bremse, Faiveley, and Nabtesco, but the above-mentioned return devices cannot be used universally for rail vehicles with different types of braking systems. For different batches, The transportation of different types of rail vehicles often needs to be processed to produce a specific return device, which greatly increases the transportation cost
