Abstract
This paper proposes an efficient precision acceleration with temperature and humidity acquisition system based on 24-bit A/D Converter, IIC temperature and humidity sensor, Ethernet controller and microcontroller. This paper expounds in detail the realization of acquisition hardware, UDP protocol in microcontroller, the acquisition software as well as many other important aspects of the system. On the basis of the foregoing, build the entire acquisition system and apply it to the road roughness measuring instrument. Through the practice of the vehicle-mounted environment inspection, experimental results show that this system can stable operation for a long time and have a good application prospect.
