Embodiment Construction

[0093] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0094] refer to figure 1 , shows a flow chart of an embodiment of a method for identifying the working state of a hybrid shunting locomotive in the present application, the method includes a first stage and a second stage, wherein the first stage is a learning period, and the second stage is a working Expect.

[0095] During the learning period, it is mainly to learn the curve of the sum of output power of multiple drive motors of shunting locomotives working in typical railway stations, such as section stations, marshalling stations, intermediate stations, etc., so as to determine the parameters in the identification of working states ; Then in the working period, it mainly collects the output power of...

Abstract

The invention provides a method and a system for recognizing working conditions of a hybrid-power shunting engine. The recognizing method includes: a first stage: obtaining an output power sum curve of the shunting engine in a specific working state; sampling the output power sum curve, wherein each sample is a section of output power sum curve, sampling time is ts seconds, and sampling interval is tf seconds; calculating a first characteristic parameter of each section of output power sum curve; and confirming control parameters required by working state recognition according to the specific working state and the first characteristic parameter; and a second stage: collecting output power sum value of a driving motor in each ts second of the current shunting engine, wherein collecting gap is equal to the sampling interval tf; enabling the output power sum value in each ts second to be a segment, and calculating a second characteristic parameter of the segment; and confirming working state of the shunting engine according to the control parameter acquired in the first stage and the second characteristic parameter.

Description

technical field [0001] The present application relates to the technical field of diesel locomotive control, in particular to a method and system for identifying the working state of a hybrid electric shunting locomotive. Background technique [0002] Hybrid diesel locomotive is a green model in the development direction of rail transit. Hybrid technology is very suitable for electric drive diesel locomotives, especially shunting locomotives. The shunting locomotive has the characteristics of long idling time and low running speed. The use of hybrid technology can greatly improve the fuel economy of shunting locomotives and reduce their emissions, which is of great significance to the work of shunting locomotives in special environments such as tunnels with poor ventilation. [0003] The control strategy is the core of the hybrid shunting locomotive, which controls the energy distribution of the shunting locomotive, and the control strategy is closely related to the working...
