Pavement continuous compaction quality monitoring method, acquisition terminal, monitoring terminal and system

Abstract

The invention discloses a pavement continuous compaction quality monitoring method, an acquisition terminal, a monitoring terminal and a system, and relates to the field of pavement continuous compaction quality monitoring. The invention aims to solve the problem that in the prior art, real-time and efficient monitoring and management cannot be carried out on the filling and compacting project. According to the pavement compaction quality monitoring system, the acquisition terminal and the monitoring terminal are connected through the Internet, the acquisition terminal acquires and analyzes real-time data of pavement compaction quality, and the monitoring terminal analyzes and monitors the real-time data. The working efficiency and the management level of the construction process are effectively improved, and the construction quality is ensured.

Description

technical field [0001] The invention relates to the field of continuous compaction quality monitoring of road surfaces, in particular to a method for monitoring continuous compaction quality of road surfaces, a collection terminal, a monitoring terminal and a system. Background technique [0002] Whether it is a railway subgrade or a highway subgrade (pavement), it is formed by rolling with a rolling machine. The compaction quality of the subgrade is mainly reflected in the uniformity and degree. The compaction quality of the subgrade is to ensure the safety, stability and comfort of the locomotive (vehicle). The key to operation, the scientific and reasonable monitoring of the roadbed (pavement) rolling process and rolling behavior is of great significance to ensure the quality of roadbed (pavement) construction. [0003] In 2015, the China Railway Corporation promulgated the enterprise standard "Technical Regulations for Continuous Compaction Control of Railway Subgrade Fi...

AI Technical Summary

Problems solved by technology

[0004] (1) More products still use the harmonic ratio (CMV) index. The CMV index only has a good correlation with a few fillers and the previous conventional indicators. For most fillers, the correlation with the previous conventional indicators is poor, and sometimes there is no Correlation, resulting in CMV indicators can not be applied;

[0005] (2) The product functions are relatively simple, some can only collect compaction indicators, and some can only describe the number of rolling times, failing to realize the comprehensive monitoring of the rolling process, such as: the rolling speed of the road roller, the vibration frequency of the road roller, etc. Process parameters, and these parameters play a great role in the rolling quality;

[0006] (3) Most of the products are only on-site real-time monitoring, simple data reproduction after construction, no in-depth analysis of collected data, and lack of scientific and reasonable guidance for the construction process

[0007] (4) The degree of networked monitoring equipment is low, and the collected data is fragmented, which cannot meet the requirements of digital construction proposed by the Railway Corporation

On the one hand, it is impossible to centralize a large amount of collected data to mine relevant measures and methods that have general guiding significance for the construction process; on the other hand, it is impossible to collect data on the overall route, and there is also a lack of data support for the causes and prevention of roadbed (pavement) diseases in the future
