Infrared Detection Technology-Based Safety Monitoring of Oxygen Cylinder Filling Process

Abstract

During the process of filling the oxygen cylinder, if the flammable gases such as H2 and C2H2 are also filled into the cylinder, there may be an explosion, which may threaten the production safety. In order to prevent this, a real-time detection of cylinder temperature plays a vital important role in the filling process of oxygen cylinder. This paper designs a temperature early warning system and error correction method. The system is mainly composed of a STM32 microprocessor, a MLX90614 infrared temperature measurement module and a LCD display. By measuring the temperature which reaches the limit of alarming, the cylinder temperature obtained by the real-time detecting of infrared temperature measurement module will be transferred to the single-chip microcomputer for further processing. In the end, data will be transmitted to the LCD display and the buzzer from the single-chip microcomputer.
