Problems solved by technology

[0006] In order to solve the problems existing in the existing technology for roads with completely different road conditions, if only the same algorithm is used to optimize the road maintenance decision, the matching degree of the algorithm is not high, the pertinence is not strong, and the maintenance plan and maintenance cost are not enough. Reasonable, technical issues affecting the accuracy of maintenance decisions

Embodiment 1

[0058] like figure 1 As shown, the present invention provides a road surface maintenance intelligent decision-making system based on big data, including a road surface information import module, a road surface condition evaluation module, a road surface maintenance expert plan database, a road surface maintenance plan generation module and a road surface maintenance cost calculation module;

[0059] The road surface information import module is used to import the basic information of the road section to be maintained and the sub-index index of the road surface condition; it is also used to define the basic unit road section and match the sub-item index index of the road surface condition to the basic unit road section;

[0060] The pavement condition evaluation module is used to calculate the pavement performance index of the basic unit road section according to the sub-index index of the pavement condition, combined with the first mapping relation table; 2. The mapping relati...

Embodiment 2

[0117] The present invention provides a road surface maintenance intelligent decision-making method based on big data, using the big data-based road surface maintenance intelligent decision-making system in Embodiment 1 to carry out the decision-making of the road surface maintenance plan, such as figure 2 shown, including the following steps:

[0118] Use the road surface information import module to import the basic information of the road section to be maintained and the sub-index index of the road surface condition, define the basic unit road section, and match the sub-item index index of the road surface condition to the basic unit road section;

[0119] According to the sub-index index of the road surface condition, the road surface service performance index of the basic unit road section is calculated by using the road surface condition evaluation module combined with the first mapping relationship table;

[0120] According to the pavement use performance index and the...

Abstract

The invention provides a pavement maintenance intelligent decision-making system and method based on big data. The system comprises a pavement information import module, a pavement condition evaluation module, a pavement maintenance expert scheme database, a pavement maintenance scheme generation module and a pavement maintenance cost calculation module. The pavement information import module is used for importing data and defining a basic unit road section; the pavement condition evaluation module is used for calculating a pavement condition grade; wherein a plurality of existing pavement maintenance expert schemes are stored in the pavement maintenance expert scheme database; the pavement maintenance scheme generation module is used for automatically generating a plurality of pavement maintenance schemes by using a decision tree algorithm; the pavement maintenance cost measuring and calculating module is used for calculating a maintenance total cost range value, selecting an optimalpavement maintenance scheme by using a genetic algorithm and distributing pavement maintenance funds of the basic unit road section; the technical problem that the maintenance decision accuracy is affected due to the fact that a maintenance scheme and maintenance cost formulated in the prior art are not reasonable enough can be solved.

Description

technical field [0001] The invention relates to the technical field of highway pavement maintenance, in particular to an intelligent decision-making system and method for pavement maintenance based on big data. Background technique [0002] With the rapid development of traffic in the past 30 years, a large number of road surfaces have entered the maintenance cycle, and the workload of road surface maintenance and management is huge, and traditional technical means can no longer meet the demand. Pavement maintenance management is gradually developing in the direction of informatization, automation and intelligence. The Ministry of Communications has established a national highway database, a national trunk line network monitoring information system, and a national highway network structure reconstruction project information management system. The provinces have also gradually established provincial road information management systems. These information systems or platforms...
