Abstract: For the shortcomings of needing to plug tightening hang in, pull data line， frequently moving the control box, and squatting operation in the process of detecting the road surface with the traditional wired portable deflection instrument, wired data transmission mode adopted on the deflection instrument was changed to wireless transmission, at the same time used the popular, easy to carry, and simple operation Android handheld devices as a wireless data receiving and processing hardware platform, and on which can be developed for data acquisition, image display, storage and query of the measurement procedures. Some of the unwieldy structure was removed, such as data lines, control boxes, etc. Many convenients were omitted such as plug and tighten aviation plug, pull the data line, frequently moving the control box, squatting operation encountered when the operator making measurement. It is easy to implement data acquisition, analysis and storage. This paper detailedly introduces the design and implementation of this measurement software based on Android.
