Car navigation system for height limit
LI Xue-yan · 2008
In view of the current increasing bridge damage caused by the ultra-high-gauge vehicles,a plan of car navigation system for height limit is proposed to get the accurate measurement of the car and provide intelligent guidance for the nearest route according to the height of car.By using the C language and the Qt graph programming language,a whole system are designed including ultrasonic sensing altimeter,navigation service terminal and the road bridge database server.At present,all the system function modules have been achieved.The distributing system architecture is transplantable,which makes it able to be rapidly and easily installed in other cities at the urban entrance.
