摘要
弯曲蠕变速率是评价沥青混合料抗裂性能的一个重要指标。作为LD201型全自动弯曲蠕变试验系统的测量控制部分,本系统的设计基于C8051F410,由单片机控制加载、卸载、水循环系统、恒温控制、位移数据采集存储,计算弯曲蠕变速率,在LCD上显示试验参数和动态跨中挠度时间曲线图。设计了基于Visual Basic的上位机控制软件,实现了数据处理、试验曲线、试验报告的打印等功能,界面友好,操作简单。
Bending creep rate is an important index of performance evaluating anti-cracking characteristic of asphalt mixture. As the part measure and control of LD201 bending creep test system of asphalt mixture,the design of this system is based on the microcontroller c8051f410.In a test period,the microcontroller controls：electric motor-start,electric motor-stop,water-cycling system,constant-temperature control,displacement date sampled and stored,the important parameter of Bending creep rate is calculated,the experiment parameters and dynamic curve of mid span deflection-time could be displayed in the LCD. The supercomputer control soft based on Visual Basic was designed. It includes data process,report print,ect. This system is good for easy operation and friendly interface.
