摘　　要：本文通过对沥青的特殊形态、不同计量方法的分析比较,提出了利用超声波原理基于单片机控制的非接触性计量方式,根据超声波传播速度、传播距离的时间间隔得到罐内沥青空高,进而计算出实际沥青液位高度,根据沥青的实时密度,得到沥青的质量和体积。在单片机的控制下,对不间断的沥青收发作业,也可以实时显示出沥青的液面变化。此计量方法,既解决了沥青不同相态的计量问题,还能对不同温度下、不同相态的沥青实现计量的自动化,提升了沥青的现代化加工、管理水平,也为企业带来了良好的经济效益。This paper analyzes and compares the special form of asphalt and different measurement methods,a non-contact measurement method based on the principle of ultrasonic and single-chip microcomputer control is proposed,according to the time interval of ultrasonic propagation speed and distance,the empty height of asphalt in the tank is obtained,then the actual asphalt level is calculated,according to the real-time density of asphalt,get the mass and volume of asphalt.Under the control of single chip microcomputer,for continuous asphalt receiving and dispatching operation,it can also display the change of asphalt level in real time.This method of measurement,it not only solves the measurement problem of different phase state of asphalt,at the same time,it can also realize the automation of asphalt measurement under different temperatures and different phase states,it not only improves the modern processing and management level of asphalt,but also brings good economic benefits for enterprises.
