Problems solved by technology

[0002] In the construction process of railway subgrade, especially in the construction process of high-speed railway subgrade, most of the road rollers used are controlled by human driving, and the driving of vibratory road rollers will have certain instability problems due to human intervention, which will have a great impact on the quality of the subgrade. At present, there is no relevant research on how to judge the stability of the driving posture of the vibratory roller through the real-time indicators on the spot

Embodiment 1

[0078] The following is an example of the process of testing this embodiment in a test section. During the test, the loose paving of the filler is carried out on the high-speed railway embankment, and the scraping machine is used to carry out further scraping work on the spot, and in the operation section after scraping Plan the test area, including the length and width of the test area, the starting point and the end point of the vibratory roller entering the work area, and the total length of the test area is recorded as L (m). The vibratory roller used in the test is 26.7t, of which the front wheel counterweight is 17.1t and the rear wheel is 9.6t. There are two normal working states of the vibratory roller, one of which is weak vibration with a vibration frequency of 31Hz, a nominal amplitude of 1.03mm, and an exciting force of 275kN, and the other is strong vibration with a vibration frequency of 27Hz and a nominal amplitude of is 2.05mm, and the exciting force is 416kN. ...

Embodiment 2

[0141] Such as figure 2 As shown, this embodiment provides a device for judging the attitude stability of a road roller, and the device includes a first acquisition 71 , a first calculation module 72 , a second calculation module 73 and a third calculation module 74 .

[0142] The first obtaining module 71 is used to obtain the first acceleration time history curve and the second acceleration time history curve of the road roller, the first acceleration time history curve and the second acceleration time history curve are both set in the The acceleration sensor on the road roller is collected, and the first acceleration time-history curve and the second acceleration time-history curve are respectively collected during two adjacent compaction constructions of the same roadbed by the road roller;

[0143] The first calculation module 72 is configured to equally divide the first acceleration time-history curve into a plurality of first sub-curves, divide the second acceleration ...

Embodiment 3

[0170] Corresponding to the above method embodiment, the embodiment of the present disclosure also provides a device for judging the attitude stability of a road roller. The device for judging the attitude stability of a road roller described below and the method for judging the attitude stability of a road roller described above are mutually Corresponding reference.

[0171] image 3 It is a block diagram of a device 800 for judging attitude stability of a road roller according to an exemplary embodiment. Such as image 3 As shown, the equipment 800 for judging the attitude stability of a road roller may include: a processor 801 and a memory 802 . The equipment 800 for judging the attitude stability of a road roller may also include one or more of a multimedia component 803 , an input / output (I / O) interface 804 , and a communication component 805 .

[0172] Wherein, the processor 801 is used to control the overall operation of the equipment 800 for judging the attitude sta...

Abstract

The invention relates to the technical field of construction equipment, and in particular, relates to a road roller attitude stability judgment method, device and equipment and a readable storage medium. The method comprises the steps: acquiring a first acceleration time-history curve and a second acceleration time-history curve; equally dividing the first acceleration time-history curve into a plurality of first sub-curves, and equally dividing the second acceleration time-history curve into a plurality of second sub-curves; calculating to obtain a value of a first foundation compaction indexcorresponding to each first sub-curve and a value of a second foundation compaction index corresponding to each second sub-curve; and calculating to obtain correlation parameters, and judging the stability of the driving posture of the road roller according to the values of the correlation parameters. An acceleration sensor is arranged on the vibratory road roller, acceleration time-history datacollected by the acceleration sensor is analyzed, then the comprehensive posture and stability of the road roller in the operation process are analyzed, and a clear feedback index is provided for thecompaction quality of a roadbed and the driving level of a driver of the road roller.
