Embodiment

[0016] An embodiment, a method for real-time monitoring of the operating state of construction machinery, using a six-axis sensor to collect the angular velocity and acceleration on the three axes of the construction machinery at a frequency of 100 Hz;

[0017] For angular velocity, X fixed windows are taken sequentially on each axis, and A angular velocity data are collected in each fixed window, and the data in each fixed window is used to subtract the median of the data in the respective windows, and the obtained difference is taken as absolute Value, take the average of the obtained absolute values; then add the three averages of the corresponding windows of the three axes into a sum value; thus, to obtain X sum values, take the 0.75th percentile of the X sum value array Number (the 0.75 quantile of an array refers to the number that ranks in three quarters after the array is arranged from small to large. For example, a set of 40 numbers from small to large, the thirtieth p...

Abstract

The invention discloses a method for real-time monitoring of the operating state of construction machinery, which is used in the technical field of construction machinery management. The invention collects and processes the three-axis angular velocity and acceleration of the construction machinery and compares them with the threshold values ​​of the angular velocity and acceleration when the machinery is working normally. , which can effectively monitor the operation status of machinery. Compared with manual verification, it has higher efficiency and higher accuracy of results, which can reduce the occurrence of missed reports and over-reported situations, and avoid the problems of false reporting of workload and working hours.

Description

technical field [0001] The invention relates to the technical field of construction machinery management, in particular to a method for real-time monitoring of the running state of construction machinery. Background technique [0002] Construction machinery is mainly used in various construction projects, and the working environment is diverse and relatively harsh. In order to improve the management efficiency of construction machinery and reduce the management cost of construction machinery, it is necessary to collect statistics on the working hours and operating status information of construction machinery. At present, the field of engineering management usually still uses the method of manual verification to carry out the statistics of the above-mentioned information. The workload is heavy and the statistical data has large deviations. question. [0003] The Chinese invention patent "Method and system for monitoring the operating state of construction machinery" (publica...
