Automatic Section Detection Accumulated Distance Start Stop Trigger Intelligent Eight-Wheel Pavement Roughness Tester

Product Description

Product Description

Intelligent Eight-Wheel Pavement Roughness Tester

The controller is designed in a separate unit. A wireless data collector operating in the ISM frequency band samples the instantaneous displacement data and mileage data, and then transmits them to the main controller. The main controller then completes the data recording, calculation, storage, and printing. Compared with the current three-meter straight ruler measurement and other similar measuring instruments, this instrument not only has the advantages of high measurement accuracy, fast speed, reliable data, and scientific evaluation, but also is simple to operate, reliable in operation, and significantly reduces labor intensity, improving work efficiency and economic benefits. It is applicable for the construction inspection, completion acceptance, and road maintenance of roads such as highways, urban roads, squares, and airport runways. It can also provide reliable pavement analysis data for teaching, design, and research units.

Product features

1. The controller is of the split type, and the main controller and data collector use wireless communication in the ISM frequency band.
2. The data collector is powered by batteries and can continuously measure for 20 hours, covering at least 150 km of road sections.
3. The main controller features a 7-inch TFT true-color LCD screen with Chinese display and full touch operation.
4. It can display the displacement data curve of the current test section, the deviation curve of the displacement in the previous measurement section from the average value, and the change curve of the smoothness within the last 1 km.
5. All test values, set values, instantaneous values can be displayed on the same screen.
6. It has an accurate battery level monitoring program that can display the current remaining battery power and the battery life.
7. The test data is automatically saved, with built-in 1Mb memory, capable of storing at least 100 km of test data.
8. It comes with a thermal-sensitive micro printer and can be set to print continuously during the test.
9. The positive and negative out-of-tolerance times, cumulative values, section area and base surface area, average value, test speed, and smoothness value for each measurement section (100 meters) are automatically saved, displayed, viewed, and printed.
10. The test section number (road number, mileage number, pole number, road width number, out-of-tolerance setting, sampling interval) is incremented or decremented automatically by one each time it is printed.
11. It has a complete data management program, and the system can retrieve the same data based on the user input of the test number and test time.
