Wireless Load Weight Monitoring Via a Mobile Device Based on Air Suspension PressurePublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: 2012 Dallas, Texas, July 29 - August 1, 2012 121337075.(doi:10.13031/2013.42112)Authors: Alexander W Layton, Andrew D Balmos, Derek L Hancock, Aaron C Ault, James V Krogmeier, Dennis R Buckmaster Keywords: Air bag, load, suspension, truck, weight, wireless A system was designed and tested to measure pressure in the airbag suspension components of an over-the-road tractor trailer and use those signals to wirelessly display load weight. Three subcomponents (a HID -- human interface device and two DPUs -- digital processing units) were required and communicated using Zigbee wireless devices. Except for a region directly in front of the cab, the unit transmitted weights up to 45 m. Effect of number of calibration points on system accuracy was evaluated. (Download PDF) (Export to EndNotes)
