Problems solved by technology

Among them, there are differences in the coasting control methods designed by various on-board signal system manufacturers. Some manufacturers realize it by outputting the minimum traction level in the traction state. This implementation method causes the cruise mode to fail to correspond to the vehicle’s coasting, and the train still receives traction commands. and execute the minimum traction state
[0003] The inventors of the present application found in the process of realizing the present invention that the traction motor still outputs excitation current and work during the minimum traction process in the cruising form of the above-mentioned solution of the prior art, resulting in long working hours, high energy consumption, and high temperature of the motor. Elevation and short lifespan

Embodiment 1

[0038] Such as figure 1 As shown, this embodiment discloses a method for vehicle interventional coasting control, which is characterized in that it includes the following steps:

[0039] S1. Acquiring train running status information.

[0040] Specifically, the train running state information includes ATO traction state, ATO output control level and train speed.

[0041] S2. Judging whether the train running state information satisfies a preset coasting rule.

[0042] Specifically in this embodiment, the coasting rule is: the ATO traction state is the traction state, and, the ATO output control level is greater than the preset voltage threshold, and, the train speed is greater than the preset speed threshold, and, the train speed change rate is less than Preset rate-of-change threshold.

Embodiment approach

[0043] Specifically, when judging whether the train running status information satisfies the preset coasting rules, a specific implementation method is as follows:

[0044] When the AT0 traction state is high level, it is judged that the signal system outputs a traction command, which meets one of the control conditions; when the AT0 traction state is low level, it is judged that the signal system does not output a traction command, which does not meet the control conditions;

[0045] Compare the collected ATO control level bit with the set threshold 2.8V, if it is less than the set threshold, it is judged to meet one of the control conditions;

[0046] Convert the collected speed sensor signal into a real-time speed value; compare the speed value with the set threshold value of 20km / h, if it is greater than the set threshold value, it is judged to meet one of the control conditions;

[0047] Compare the rate of change of speed with the set threshold of 2km / h per second, if it...

Embodiment 2

[0053] Such as figure 2 As shown, this embodiment discloses a device for vehicle intervention coasting control, including:

[0054] The collection module is used to collect train operation state information; specifically, the operation state information collected by the collection module includes: ATO traction state, ATO output control level and train speed sensor signal;

[0055] The logic control module is used to process the collected information and output control signals; specifically, the logic control module judges whether the train running state information meets the preset coasting rules, and outputs the coasting signal when the train running state information meets the coasting rules .

[0056] Specifically in this embodiment, the coasting rule is: the ATO traction state is the traction state, and, the ATO output control level is greater than the preset voltage threshold, and, the train speed is greater than the preset speed threshold, and, the train speed change r...

Abstract

The invention discloses a method for vehicle intervention coasting control, including S1, acquiring train running state information; the train running state information includes ATO traction state, ATO output control level, train speed and train speed change rate; S2, Judging whether the train running state information satisfies a preset coasting rule; S3. When the train running state information satisfies the coasting rule, intervene in ATO control to make the train enter a coasting state. The invention also discloses a vehicle intervention type coasting control device. The invention can realize the coasting control of the vehicle in the ATO mode by judging various running state information of the train, thereby effectively reducing the traction energy consumption of the vehicle and realizing energy saving of the train At the same time, it can reduce the temperature rise of the traction motor of the train and improve the life of the traction motor.

Description

technical field [0001] The invention belongs to the field of energy-saving control of trains, and mainly relates to a method and device for vehicle intervention coasting control. Background technique [0002] The ATO automatic operation of rail transit vehicles is divided into three forms: traction, braking and cruising, which correspond to the traction, braking and idling of trains respectively. Among them, traction and braking are respectively required to provide acceleration and deceleration for trains, and cruising is idling. The behavior requires the train to keep coasting. Among them, there are differences in the coasting control methods designed by various on-board signal system manufacturers. Some manufacturers realize it by outputting the minimum traction level in the traction state. This implementation method causes the cruise mode to fail to correspond to the vehicle’s coasting, and the train still receives traction commands. And implement the minimum traction st...
