[0002] Oxygen cylinders are high-pressure containers used for storing and transporting oxygen. They are generally made of alloy structural steel through hot stamping and pressing, and are cylindrical in shape. They are widely used in welding, hospitals, and other fields. To ensure cost-effectiveness, oxygen cylinders can be refilled and reused. During the filling process, oxygen cylinders will generate heat to varying degrees, some normally, some abnormally, and some even dangerously hot enough to cause spontaneous combustion. To promptly detect abnormal heating, workers judge the temperature of the cylinder by touching the cylinder wall. If an abnormal temperature is detected based on experience, filling of that cylinder is immediately stopped.

The CPU chip is electrically connected to an alarm. The CPU chip compares the real-time temperature collected by the temperature probe with the maximum warning temperature value of 60°C. Oxygen cylinders with a real-time temperature greater than 60°C are referred to as dangerous oxygen cylinders. When a dangerous oxygen cylinder is detected, the CPU chip controls the alarm to sound and emit a red light, immediately stopping oxygen filling and evacuating personnel in a timely manner.
