Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049]In the process of preprocessing the data, it is found that the running speed of the train changes greatly, it may encounter situations such as turning, changing tracks, etc., and due to the error of the sensor, the speed data may have missing values, etc., so the missing value Complementary value processing and denoising processing are carried out, and then an automatic identification method for high-speed train operators based on fuzzy membership is established.

[0050] Such as Figure 1-3 As shown, a method for determining the operating conditions of high-speed trains based on fuzzy membership degree is implemented according to the following steps:

[0051] Step 1. Denoise the speed data generated by the train operation, specifically:

[0052] Step (1.1), collecting the running speed v of the high-speed train, and generating the sp...

Abstract

The invention discloses a method for determining the operating condition of a high-speed train based on fuzzy membership. The method includes the following steps of: 1, de-noising speed data generated by a running train; 2, sampling the de-noised data; and 3, determining operating condition of the high-speed train. According to the analysis of the speed data generated by the running train, it is found that the high-speed train parks about two minutes, a plurality of operating conditions are present in one operation cycle, and the high-speed train still changes in speed to a certain extent when the high-speed train accelerates to a certain speed. Therefore, according to the idea of big data, the method de-noise the speed data first, and then uses the fuzziness of the operating conditions of the high-speed train to select a fuzzy variable and a membership function so as to determine a fuzzy membership function and determine the operating condition of the high-speed train by fuzzy reasoning, thereby solving difficulty in determining the operating condition of the train.

Description

technical field [0001] The invention belongs to the technical field of automatic identification of operating conditions of high-speed trains, and in particular relates to a method for determining operating conditions of high-speed trains based on fuzzy membership degrees. Background technique [0002] With the rapid development of high-speed trains in my country and the continuous increase in operating mileage, trains are developing in the direction of high-power, high-speed, and heavy-duty trains, and safety has become an eternal theme of railway transportation. During the operation of the train, when there are sudden changes in the environment, such as track changes, turns, ups and downs, heading and leaving the station, etc., the operating conditions of the train will change. In fact, during the operation of the train, The operating conditions include not only traction operation, but also inertial operation and braking operation, that is, acceleration, smooth operation an...
