Problems solved by technology

Due to the low wave velocity of the air brake, the transmission speed of the train brake control signal from the locomotive to the rear is slow, and the braking synchronization of the rolling stock is poor. The greater the vehicle axle load, the longer the train formation, the greater the longitudinal force inside the train, and the The greater the impact force on the line and the line, the greater the damage, and it also increases the risk of hook breakage and derailment

Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] Such as figure 1 As shown, a radio air brake control system for railway freight cars includes a locomotive brake control system and each vehicle brake control system arranged in sequence.

[0017] The locomotive brake control system includes a manipulator 1, a display screen 2 and a control module 3, the control module 3 is respectively connected to the manipulator 1 and the display screen 2 through a cable 4, and the manipulator 1 is used for driver control and manipulation.

Abstract

The invention discloses a wireless idle brake control system and control method for a railway wagon. The control system comprises a locomotive brake control system and a vehicle brake control system; the locomotive brake control system comprises an operator, a display screen and a control module; the vehicle brake control system comprises an electric control device and an execution module; the control module is communicated with an electric control device of each vehicle by a wireless ad hoc network; the control module and the electric control module of each vehicle are nodes of the wireless ad hoc network. By using the wireless ad hoc network technology, in the operation of a railway wagon train, a brake release signal becomes a wireless network signal and is transmitted to the rear vehicles, and the transmission speed is improved, so the rear vehicles act at the time as consistent as possible, the longitudinal force in the brake process of the train is reduced, the impact among the vehicles is reduced, a bus cable does not need to be arranged on the train due to the wireless signal transmission mode, the operation that stations are arranged along the railway line as relay points is not needed, and the influence on the environment of the railway line is smaller.

Description

technical field [0001] The invention belongs to the technical field of railway freight car braking control, and in particular relates to a radio air brake control system and a control method for railway freight cars. Background technique [0002] For railway freight trains, there is no power supply on general freight trains, and pure air brake systems have been used for brake control. Due to the low wave velocity of the air brake, the transmission speed of the train brake control signal from the locomotive to the rear is slow, and the braking synchronization of the rolling stock is poor. The greater the vehicle axle load, the longer the train formation, the greater the longitudinal force inside the train, and the The greater the impact force and the greater the damage to the line, the greater the risk of broken hooks and derailment. In order to improve the synchronization of train braking relief, it is necessary to increase the wave speed of train braking relief. Contents...
