The Design of Embedded Apparatus Based on Time-triggered Scheduling Method

摘要

A device of petroleum asphalt's characteristics measuring system was designed in this study. The differential auto-calibration voltage-frequency conversion technology with multi-benchmark resources was applied to measure the temperature. Time-triggered scheduling method was introduced into software design. The intelligent PID algorithm was used for controlling the change rate of temperature. These experiment results showed that the device had high measuring accuracy, and reliability and stability.
