Abstract
Measuring the strain of the body structure of uavs in off-road environment is the basis to ensure the reliable work of uavs and to optimize the structure of uavs. The goal of this project is to design a body structure strain wireless data acquisition system based on ultra-wideband wireless communication technology UWB, which USES the strain gauge pasted on the body to measure the deformation of the car body in real time, and send it to the top position wirelessly to complete the data storage, display and processing.
The scope of knowledge involved in this topic: theoretical mechanics, material mechanics, computer technology, testing technology, electrical and electronics, software design and development, etc.
The main work contents of this project include:
1. Data collection and program demonstration;
2. Design circuit schematic diagram and PCB diagram, and make measurement nodes;
3. Completed the strain simulation of vehicle structure under different driving conditions, and designed the layout scheme of measuring points.
Key words: strain test; UWB; PCB. The finite element.
