A Modular Data Acquisition System for Heavy Vehicle Simulator Tests
This paper describes the design and fabrication of a Data Acquisition (DAQ) system that uses the latest hardware and software technology. Two systems were built to work with two active Heavy Vehicle Simulators (HVS) at the University of California Pavement Research Center (UCPRC). The new DAQ systems replaced the old ones that were built in 2005. The upgrade was considered necessary because the data acquisition hardware used in the old systems were no longer actively supported by the vendor. The new system maintains the ability to measure temperature, displacement, strain, pressure (voltage) and surface profile. In addition, the new system can also measure resistance and current. A modular design was adopted to facilitate future upgrades without having to replace all of the components. It also allows sharing and balancing of the DAQ needs between the two HVS units. It is believed that the design of the new DAQ system is sufficiently generic and can provide useful information for other accelerated pavement testing programs.
