Two-Level Computer Control System of Rock Crystal Growth——the design and application of lower computer

This paper introduces the construction of two-level computer measurement and control system of rock crystal growing in the high pressure reactor. It focuses on the method of task installation and the factor which should be considered about the lower-computer in the running environment of Real Time Multi Task OS-iDCX51. The paper also offers the control tactics used. The system's control precision is about one centigrade,and it meets well the technological inquirements on the spot.
