Intelligent Control System of Mine Air Door

At present, the simple control triggered by switching value was mostly applied to the control system of mine air door, which resulted in misidentification of the goals getting through the air door. The goals passing through the air door were monitored by the combination of embedded operating system and identity fusion algorithm so that the turn-on time of air door could be controlled in the reasonable range. The chips of ARM Cortex-M3 series were used as microcontroller of this system; in order to realize the control of multitask and interrupt priority level, the RT-thread was adopted as embedded operating system.
