Subgrade rolling monitoring system and calculation method of number of subgrade rolling times based on RGB algorithm

Abstract

The invention discloses a subgrade rolling monitoring system and calculation method of the number of subgrade rolling times based on an RGB algorithm. By setting the RGB value of the number of rollingtimes by a road roller every time, a certain rolling area is expressed by a point on a screen, the computer screen initial display RGB value is (255 255 255), the RGB values of corresponding points on the screen are changed in real time according to the rolled position and the rolled area by the road roller, real-time monitoring is conducted on the number of on-site rolling times, and the road roller is commanded to operate. After construction is completed, by analyzing the RGB values, the number of points reaching the required rolling number of times can be obtained, and qualified points andunqualified points are displayed on the screen visually. Through rolling state images displayed by the system in real time, the phenomena of rolling leakage and less rolling can be avoided, and oncethe phenomena of rolling leakage and less rolling are found, construction personnel can conduct instant rolling supplement. Meanwhile, the construction personnel can also avoid the overpressure site and the overpressure phenomenon, and redundant work which is unnecessary and even unfavorable to the construction quality is reduced.

Description

technical field [0001] A roadbed rolling frequency based on RGB algorithm involves a special positioning technology, in particular, a collection sensor based on positioning technology, which is a method, system and device for converting traditional construction industry phenomena into computer credible electronic information. And this method is combined with the standard colors commonly used in the current industry to reflect the rolling condition of the roadbed with color superimposition, and use this to judge the number and proportion of rolling. Background technique [0002] In highways, railways, airports, dams, municipal projects, etc., filling construction is the most critical process, and the compaction construction link is a difficult problem to control. The actual number of rolling times and rolling speed are greatly affected by human factors, and objective lack of scientific and reliable management methods, it is difficult to achieve real controllability; the sampl...

Problems solved by technology

[0002] In highways, railways, airports, dams, municipal projects, etc., filling construction is the most critical process, and the compaction construction link is a difficult problem to control. The actual number of rolling times and rolling speed are greatly affected by human factors, and objective lack of scientific and reliable management methods, it is difficult to achieve real controllability; the sampling results of quality evaluation indicators such as compaction degree and settlement difference cannot fully and truly reflect the quality of subgrade compaction; when multiple rollers are working, it is impossible to know the compaction Whether the number is qualified and whether the rolling area is fully covered; under low vision conditions (such as night construction) it is easy to cause pressure leakage, resulting in uneven compaction
