Train information management device and device control method

Abstract

The invention provides a train information management device and a device control method, the train information management device comprising: a position detection part (11); a regeneration state detection part (13) for detecting the state of using regenerative braking; A route information holding unit (14) for information on sections with a high possibility of movement; an air remaining amount calculation unit (15) for calculating the air remaining amount of the air tank; and a compressor control unit (12) for controlling the compressor ), the compressor control unit (12) in the process of traveling to a point where the distance from the section where the possibility of using the brake is high is less than or equal to a certain value, and in the regeneration preparation state without using the regenerative braking When the residual air amount becomes 0%, the compressor starts to generate compressed air, and in the regenerative state using regenerative braking, the compressor control unit (12) causes the compressor to generate compressed air when the residual air amount is less than 100%, and then In the normal state, the compressor control unit (12) causes the compressor to start generating compressed air when the residual air amount becomes a first threshold value greater than 0%, and when the residual air amount becomes greater than the first threshold value and greater than 100% When the second threshold value is small, the generation of compressed air is terminated.

Description

technical field [0001] The present invention relates to a train information management device, and more particularly to a train management device that facilitates effective use of regenerative power generated when electric braking is used. Background technique [0002] The train information management device collects and manages status data of various equipment mounted on each car of the train, and can individually control the equipment based on the collected status data. The equipment to be controlled is a power converter that converts the power supplied by the overhead line and supplies it to the main motor, auxiliary equipment, air conditioners, lighting equipment, brakes, and the like. [0003] In recent years, trains are generally equipped with regenerative braking, which uses the main motor to perform braking, and sends the power generated at this time back to the trolley line for use by other trains. As a problem of regenerative braking, there is a problem that, in t...

Problems solved by technology

[0008] However, in the prior art described above, there is a problem that the power can be used only when the regeneration fails and it happens that the pressure of the main storage tank is lowered, so that sufficient and effective use of the regenerative power cannot be achieved
