Embodiment Construction

[0033] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0034] Such as figure 1 As shown, a kind of tramway energy-saving traveling method disclosed in the present invention comprises:

[0035] S1, the tram line is divided into multiple sub-sections according to the signalized intersection and the station;

[0036] Specifically, such as Figure 5 As shown in , a tram line with a length of 2.7km, 5 stations and 7 intersections is divided into 11 subsections. In order to ensure that the trams pass through completely before the green lights at each intersection, the intersectio...

Abstract

The invention discloses an energy-saving advancing method for a tramcar. The method includes: dividing a tramcar advancing route into a plurality of subareas according to signal intersections and stations; determining the time range needed by the tramcar to pass each subarea according to the green wave band and advancing route of the tramcar; calculating the minimum traction energy consumption value of the tramcar passing each subarea at optional time in the time range needed by the tramcar to pass each subarea; calculating the total minimum traction energy consumption value of the tramcar passing all the subareas according to the minimum traction energy consumption value of the tramcar passing each subarea, and determining the advancing time, corresponding to the total minimum energy consumption value, needed by the tramcar to pass each subarea. The method has the advantages that the problem that the tramcar meets the red light due to the fact that the time loss of starting and stopping operation is not considered is avoided, the traction energy consumption during tramcar operation is lowered on the basis that green wave passing is guaranteed, and support is provided for the achieving of the traction energy saving of the tramcar.

Description

technical field [0001] The invention relates to the technical field of tramcar energy saving. More specifically, it relates to an energy-saving running method for a tram. Background technique [0002] The newly-built modern tram system in my country generally adopts the semi-independent right-of-way form, that is, it has independent right-of-way at road sections and passes at level crossings at intersections. Therefore, trams will be affected by signal lights at intersections, for example, they need to stop and wait when encountering red lights, which will weaken their advantages of being fast and punctual. Therefore, at present, green wave control is generally used to coordinate the phase difference of each signal light, so that the tram can continuously obtain green lights when running at the prescribed average speed between intersections. [0003] The green wave coordinated control method is to adjust the cycle duration of each signal light along the designated traffic ...
