Intelligent Monitoring System of Materials Subject Laboratory Based on IoT

In view of the situation that may cause flammable gas, harmful gas, smoke leakage and other damage to the health of scientific research personnel and the temperature and pressure in the experimental instrument exceed the upper limit of danger during the operation of the university materials subject laboratory, research and development Based on LAN, 4G, 5G materials subject laboratory intelligent IoT monitoring system, it is divided into four layers from bottom to top: perception execution layer, control service layer, transmission network layer, terminal application layer. After real-time measurement of abnormal environmental parameters, the IoT system automatically warns and regulates the drive exhaust fan to ensure the health of the experimental scientific research personnel. In addition, it monitors the temperature and pressure during the experiment. Once the limit is exceeded, it automatically drives the actuator to prevent fires, explosions and other accidents.
