摘　　要：通过对沥青弗拉斯脆点测定方法与过程的研究,采用多基准源实时自校正技术,提高温度的测量精度。采用分段的智能PID控制方法,有效解决了测试过程的模型非线性特性,并把合作式调度的思想引入到监控软件设计中,提高软件运行的可靠性。实验证明,本系统温度下降速度均匀,弗拉斯脆点测量精度和稳定性好,并缩短了测试时间。By the research on the measure method and process of Fraass breaking point, the real-time auto-calibration technology based on multi-benchmark resources was used for improving the temperature measure precision, and subsection intelligent PID control strategy was adopted in order to solve the measure process model＇ s nonlinear property. The cooperative scheduling theory was introduced into the software design to ensure the reliability of software. The experiments prove that the temperature＇ s decline is well-proportioned, the high measure precision and better stability of Fraass breaking point are obtained, and the experiment time is shorten.
