摘要

In order to meet the fast on-site calibration of temperature sensor and temperature measuring instruments, A kind of intellectualized high-precision temperature calibration device based on Embedding System is developed. This device based on ARM and a proportional-fuzzy self-tuning PID optimal control algorithm is characterized by high accuracy and fast response. Its performance parameter is given as following: measuring range, 35°C-600°C, accuracy, ± 0.50°C (at 600°C), resolution, 0.01°C, stability time 40 minutes(at 600°C). To ensure the portability of μC/OS-II, a set of data types is defined by authors. As same as all the real time cores, it is necessary for μC/OS-II to reject the interrupt before accessing the critical section of codes, and the interrupt is to be allowed again after the access. In this paper, the design of system, especially the porting of μC/OS-II operating system, is introduced.
