Embodiment 1
[0074] During the actual operation of the train, due to the complex road conditions such as uphill, downhill or curves, the starting and braking of subway trains are more frequent and the operating conditions are more complicated. In embodiment one, take the B2 type train operation of Nanning Metro Line 1 Guangxi University-Luban Road as an example for specific analysis. moving, its typical running speed curve is as follows figure 2 shown.
[0075] In Embodiment 1, since the train running route includes a curve, the train needs to brake and decelerate before entering the curve, so as to prevent the train from rolling over due to excessive speed after entering the curve. Specifically, S 0 -S 1 To start the acceleration phase, S 1 -S 2 is the constant speed stage, S 2 -S 3 It is the deceleration phase before the curve (deceleration through regenerative braking, which is essentially the regenerative braking phase), S 3 -S 4 is the uphill deceleration phase, S 4 -S 5 I...

The invention discloses a subway train optimization control method and a subway train optimization control device based on a matrix discrete algorithm. The subway train optimization control method comprises the following steps: acquiring train running parameters; performing segmenting separation analysis on the train running route to divide the train running route into one or more segments; according to different control sequence parameters for train running, establishing discretized matrix control models, wherein the discretized matrix control models are in one-to-one correspondence to the segments of the train running route; according to the discretized matrix control models and the train running parameters, calculating total train running energy consumption, and determining the optimal control sequence, wherein the optimal control sequence is a corresponding control sequence when the total train running energy consumption is lowest. Through the subway train optimization control method and the subway train optimization control device, a train optimization operation problem in a complex subway train running route which contains slopes and corners can be accurately solved; the subway train optimization control method and the subway train optimization control device have the advantages of adaptive coordination of a balance relation between the time and the efficiency, diverse applicable road segments, high calculating efficiency, calculating accuracy and the like.
Description
