Design of Loading Pressure Measuring Circuit of Highway Accelerated Loading Test System

摘要：

Highway accelerated loading test system is an important equipment for making test and evaluation on road surface quality.Measurement of loading pressure decides loading effect and loading efficiency. The paper introduces working principle of highway accelerated loading test system and composition of the control system,and analyzes design of loading pressure measuring circuit in detail.In order to improve signal-to-noise ratio,hardware antiinterference measure and digital filtering way are used. Test proves the loading pressure measuring circuit has the features of good linearity,high stability and high accuracy.
