    • Abstract
  • In view of problems of complex production and commissioning, inconvenient installation and maintenance, poor anti-electromagnetic interference existed in air flow sensor of coal mine air duct based on iron frame, an air flow switch sensor of air duct based on attitude recognition technology was designed. The sensor adopts principle of 3-axis acceleration sensor chip attitude detection to achieve state detection of air flow switch of air duct. The practical application shows that the sensor has advantages such as stable and reliable in detection, simple and convenience in installation and maintenance, strong in anti-electromagnetic interference.
