An evaluation method and system for an ato system itinerary scheme

An evaluation method and ATO technology, applied in general control systems, control/regulation systems, instruments, etc., can solve problems such as the inability to truly reflect the performance of the ATO system's itinerary plan and its high subjectivity, and achieve flexible evaluation methods and itinerary evaluation. Consider the effect of comprehensive and accurate evaluation results

Problems solved by technology

[0005] Since many performance parameters of the ATO system are considered in the process of planning the itinerary plan of the ATO system, such as the performance parameters such as fuel saving rate, punctuality, and automaticity of the entire itinerary, the existing two evaluation methods only use energy saving and Punctuality is two performance parameters to evaluate the ATO system itinerary plan, so the evaluation results obtained by using these two methods can only reflect the performance of the ATO system itinerary plan one-sidedly
[0006] In addition, the weights of the above performance parameters are artificially defined, which is relatively subjective, and cannot truly reflect the performance of the entire ATO system itinerary plan

Embodiment 1

[0047] The present invention provides an evaluation method for an ATO system itinerary plan, and its implementation flow is as follows figure 1 shown, including the following steps:

[0048] Step S10, according to the performance parameters of the ATO system, determine various factors that affect the optimization performance of the ATO system travel plan.

[0049] The performance parameters of the ATO system mainly include: automaticity, fuel saving rate and punctuality, respectively corresponding to the symbol f 1 , f 2 , f 3 , these performance parameters are the direct factors that affect the optimization performance of the ATO system travel scheme. Among them, fuel economy and punctuality can be directly calculated, and automaticity is determined according to the number of manual-automatic conversions and the percentage of automatic driving, so the automaticity is decomposed into the number of manual-automatic conversions and the percentage of automatic driving, which c...

[0104] The present invention also provides an evaluation system for an ATO system itinerary plan, its structure is as follows: image 3 shown, including:

[0105] A factor determination unit 101 , a factor weight determination unit 102 , a calculation unit 103 , a comparator 104 and a control unit 106 .

[0106] The factor determination unit 101 is used to determine various factors affecting the optimal performance of the ATO system itinerary scheme according to the performance parameters of the ATO system; it is connected with the factor weight determination unit 102 and the calculation unit 103, and passes the determined various factors to the factor weight determination unit 102 and computing unit 103 .

[0107] The factor weight determination unit 102 is used to determine the weight of each factor in a qualitative and quantitative manner based on the AHP analysis method; the factor weight determination unit 102 is connected to the calculation unit 103, and transmits the d...

Abstract

The invention relates to an evaluation method and system for an ATO system travel scheme. According to performance parameters of an ATO system, different factors affecting optimization performance of the ATO system travel scheme are determined. Weights of the different factors are determined through combination of a qualitative method and a quantitative method based on an AHP analysis method. Evaluation results corresponding to the factors are calculated according to representation functions of the factors and a total evaluation result of the whole ATO system is calculated according to the obtained evaluation results corresponding to the factors and the corresponding weights. Whether the total evaluation result of the ATO system travel scheme is greater than a preset evaluation result threshold value or not is judged. If that the total evaluation result of the ATO system travel scheme is greater than a preset evaluation result threshold value is judged, the ATO system travel scheme corresponding to the total evaluation result value is selected as an actual running ATO system travel scheme. According to the invention, the evaluation is comprehensive in consideration and the performance of the planned ATO system travel scheme can be reflected truly.

Description

technical field [0001] The invention relates to the field of railway transportation dispatching, in particular to an evaluation method and system for an ATO system itinerary plan. Background technique [0002] As a common means of transportation, railway locomotives have the characteristics of huge transportation volume, high speed and long transportation distance. With the rapid growth of the flow of people and goods between regions, more safety, stability and energy-saving requirements are put forward for locomotive driving. For railway locomotives with non-automated driving, there are disadvantages such as low average speed, poor safety, and inaccurate parking, and the driver's driving skills seriously affect the operation of the train. The driver's driving skills rely on long-term practice and continuous accumulation of experience, and he is only accustomed to driving on one route, so it is difficult to achieve the optimal control effect. Therefore, in view of the curr...
