Development of Multichannel Data Acquisition System Based on Wheel Load Measuring Plate

The wheel load measuring plate is a force sensor based on strain measurement, it can bear simultaneously multidimensional force load and identify radial wheel load by decoupling. The measuring plate can output multichannel voltage signal, usually each channel has the properties of weak signal, strong noise, poor anti-jamming ability. The paper discusses the development of a multichannel data acquisition system for the wheel load measuring plate and conducts the experimental verification, through the data acquisition system achieve time-sharing acquisition of multichannel data, improving the precision and anti-jamming ability of wheel load measurement system.
