Design And Implementation Of An Wifi Based Vehicle Axle Load Weighing System

vehicle axle weighing system in the current highway weight fees，rule over governancein areas such as overload limits，through getting the information of vehicle axle，manage thevehicle weight, improving road safety and reasonable fees. At present, some manufacturershave developed a few axle load weighing equipments according to market demand, but theyused a wired connection，there is a laid inconvenience，the cables often damaged and otherissues, this issue based on user demand for vehicle axle weighing，designed and implementedbased on Wi-Fi wireless portable vehicle axle weighing system，on which the key issues areanalyzed，designed and implemented the system, the main contents include:1This issue analyzes the determination of the position of the center of gravity of the carand the plate load cell structural features，a method of weight weighing system wasdesigned；2Designed based on WIFI high-precision data acquisition modules,use the plate loadcell as signal source，using high-precision and highly integrated24bit sigma-delta analog todigital converter to capture the weight signal，combined with Wi-Fi wireless technologyachieve a wireless direct communication between each weighing plate laptops and computer;3Using Visual Basic6.0technology to complete the preparation of systemsmanagement software，and tested it.Field test results show that: the system developed in this issue is stable and reliable，inuse of the weight fees，rule over governance in areas such as overload limits，it can meet theneeds of practical engineering applications.
