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

During the process of filling the oxygen cylinder, if the flammable gases such as H-2 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.
