Embodiment 1

[0065] The parameters and usage environment of each module specifically used in this embodiment are for describing the technical solution of the present invention, but the present invention is not limited thereto.

[0066] The vehicle-mounted terminal at the data collection layer has the following properties: waterproof level: IP67, weight: ≤2kg, working temperature: -40~85°C

[0067] The acquisition module on the vehicle-mounted terminal is a three-axis vibration sensor. As a vehicle-mounted portable data collector, it measures the three-axis acceleration of the vehicle during driving, and makes the y-axis along the vehicle's traveling direction, and the z-axis vertically parallel to the vehicle's height direction. The relevant technical requirements of the three-axis vibration sensor are: as a portable data collector, it can measure three-axis acceleration, and the measurement range is ±5.0g (g is the acceleration of gravity, and the value is 9.8m s -2 ); Acceleration measur...

Abstract

The invention discloses a road network flatness evaluation system and method based on vehicle vibration data, and the system comprises a vehicle-mounted terminal which is used for obtaining the vehicle vibration acceleration and GPS positioning data of a fixed line, and transmitting the collected data back in real time; the cloud server is used for receiving, analyzing and storing the data uploaded by the vehicle-mounted terminal and relates to a road network flatness evaluation algorithm; the visual cloud platform is used for displaying the road network flatness data by utilizing a GIS (Geographic Information System), carrying out quality analysis, report statistics, assistant decision and the like, and pushing the data to other system platforms; and the comfort level navigation module isused for carrying out comfort level navigation by utilizing the road network flatness data to obtain the most comfortable path between the two points. The vehicle vibration response data is acquiredby using the vehicle, acquisition, transmission, analysis and release are integrated, the road network flatness detection cost is reduced, auxiliary decision reference is provided for a maintenance management department, and meanwhile, the data can be used for comfortable route navigation and serve the public.

Description

technical field [0001] The invention relates to the technical field of road surface maintenance management, in particular to a road network smoothness evaluation system and method based on vehicle vibration data. Background technique [0002] In recent years, road development has gradually changed from focusing on road construction to focusing on both road construction and maintenance. With the increasing demand for road management and maintenance, the detection method is urgently to be changed in the direction of precision and intelligence. According to the requirements of transportation, combined with the future construction goals of road management and maintenance, the existing road surface health detection methods have been difficult to meet the urgent needs of large-scale road management and maintenance. [0003] With the continuous upgrading of testing equipment and the continuous improvement of testing methods, the road testing work in the information age is changing...
