Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] like figure 1 Shown, the clean brake control method based on rail vehicle of the present invention, its steps are:

[0032] S1: Set the time T and think that it is a new day after the time T. At this time, the total clean braking energy accumulated in the previous day needs to be cleared;

[0033] S2: Judging that the train enters the braking state, and detecting that the train has a braking command;

[0034] S3: Index the location library information, and compare and analyze the actual running position of the current vehicle, and output the "position condition" to be valid at the position that meets the preset conditions of clean braking;

[0035] S4: Index the load library information, and compare and analyze it with the actual load of the current vehicle. If the load meets the preset conditions of clean braking, the output...

Abstract

The invention relates to a cleaning brake control method based on a railway vehicle, comprising the following steps: S1: judging that the train enters a braking state, and detecting that the train hasa braking instruction; S2: indexing location library information, performing comparative analysis with the actual running position of the current vehicle, and outputting that the 'position condition'is effective at a position meeting the cleaning brake preset conditions; S3: indexing load library information, performing comparative analysis with the actual load of the current vehicle, and outputting that the 'load condition' is effective at the load meeting the cleaning brake preset conditions; S4: enabling a control module to send a 'cleaning brake flag bit' to an electric brake system under the condition that the conditions are all met; S5: comparing the total cleaning brake energy Ec with preset total cleaning brake energy ES to make a judgement; S6: after cleaning brake is ended, removing the 'cleaning brake flag bit', and recovering the electric brake function of the electric brake system. The cleaning brake control method has the advantages of being simple in principle, easy torealize and popularize, and capable of improving the cleaning effect.

Description

technical field [0001] The invention mainly relates to the technical field of rail vehicle network control, in particular to a rail vehicle-based clean braking control method, and is especially suitable for the control of rail vehicles such as urban rails and subways. Background technique [0002] With the development of rail transit technology, the brakes commonly used in subways include electric brakes and air brakes, and the two work together. Electric braking is controlled by the traction system, and air braking is controlled by the braking system. Under normal circumstances, the electric brake is used first, and the regenerative energy consumption generated by the electric brake is fully utilized. If the electric brake is insufficient, the air brake is used to supplement it. [0003] In recent years, with the development of electric transmission technology, in more and more subway projects, electric braking has basically met the needs of train braking. This makes the ...
