Problems solved by technology

[0007] At present, there are 80 to 100 sets of various types of rutting instruments in use in the country. Due to the lack of technology, the verification or calibration of these devices is basically blank, and the measurement performance of the rutting instruments participating in the testing has not been scientifically, reasonably and accurately evaluated. , has seriously affected the quality of the testing data, which is not conducive to the development of the testing work, and is not conducive to the evaluation of the quality of the tested project.

Embodiment 1

[0026] figure 1 It is a schematic flow chart of the performance measurement method of the vehicle-mounted rutting instrument of the present invention. Such as figure 1 As shown, the performance measurement method of the vehicle-mounted rutting instrument of the present invention includes

[0027] Step 101, establishing the indoor ground, including the rut model placement area and the vehicle placement area;

[0028] Step 102, establish an indoor static rut model in the rut model placement area, install the vehicle-mounted rut meter to the test vehicle, use the vehicle-mounted rut meter to measure the rut depth of the static rut model and collect static measurement data, and compare the static measurement data with the indoor static rut Compared with the true value of the rut of the model, the static measurement error is obtained;

[0029] Step 103, select an outdoor measurement road;

[0030] Step 104, establish an outdoor dynamic rut model on the outdoor measurement road,...

Embodiment 2

[0077] The difference between this embodiment and the first embodiment lies in the establishment method of the rut model. In this embodiment, by increasing the number of modules, the discrete rut model in the first embodiment is changed to a rut model with a continuously changing height, so that the rut model can be more accurately Simulate the actual rut model to more accurately evaluate the measurement performance of the vehicle-mounted rut meter.

[0078] Wherein, in step 101, the flatness of the area where the rut model is placed is lower than 2.5mm / m.

[0079] In addition to steps 102a and 102b, step 102 further includes:

[0080] Step 102c, with N 1 A second module located in the same road cross-section perpendicular to the longitudinal direction of the road establishes an indoor static rut model with continuously changing heights, and every two adjacent second modules are in contact with each other.

[0081] Figure 6 It is a structural schematic diagram of the indoo...

Abstract

The invention provides a performance measurement method of a vehicle-carried rut meter, comprising the steps of: 101, establishing an indoor ground comprising a rut model placing area and a vehicle placing area; 102, establishing an indoor static rut model in the rut model placing area, carrying out rut depth measurement on the static rut model by the vehicle-carried rut meter and acquiring the static measurement data so as to obtain a static measurement error; 103, selecting an outdoor measurement road; 104, establishing an outdoor dynamic rut model on the outdoor measurement road, carrying out rut depth measurement on the dynamic rut model by the vehicle-carried rut meter and acquiring the dynamic measurement data so as to obtain a dynamic measurement error; and 105, evaluating the performance level of the vehicle-carried rut meter according to the static measurement error and the dynamic measurement error. The performance measurement method of the vehicle-carried rut meter of the invention can scientifically, rationally and correctly measure, detect and evaluate the performances of various vehicle-carried rut meters, and is convenient to implement and beneficial for popularization; therefore, the measurement cost is reduced.

Description

technical field [0001] The invention relates to a performance measurement method, in particular to a performance measurement method of a vehicle-mounted rutting instrument. Background technique [0002] Highway is an important transportation infrastructure and one of the "arteries" of national economic development. For a long time, especially after more than 20 years of reform and opening up, road transportation has made important contribute. With the continuous development of our country's economy, the flow of passenger and cargo transportation has expanded rapidly, and it is required to continue to expand the scale of road construction. The tasks and goals of road engineering construction in the field of transportation are: to speed up the construction of expressways and national and provincial arterial lines ("five vertical and seven horizontal", "7918" projects), vigorously develop rural roads, and promote the modernization of my country's transportation. By the end of...
