Abstract
Abstract
Permeability meter plays an important role in the measurement of road seepage performance. The data deviation is easy to produce because of incorrect reading by using the manual seepage meter. Thereby, the application program based on Windows CE operating system is developed, which includes test process, data processing and battery monitoring. And the manual control, automatic delay and industry standard operation processes can be achieved by adopting the timing and event-driven modes, furthermore, it has the function of calculating standard deviation, mean value and coefficient of variation, checking out the existing data. And the recorded data can be automatically appended to the list. The software which uses the recursive median algorithm to filter the original data can monitor the dynamic change of liquid level synchronously, and can also measure the initial and final liquid level height like the manual seepage meter. It can provide a smooth curve of the seepage process. Combined with observation and data analysis, it is found that the process curve is obviously related to the phenomena of water seepage, lateral infiltration, water leakage and bubble burst, so these phenomena of water seepage process of road can be recognized through algorithm development.
