Safety monitoring and early warning system for hydrogen refueling station

The invention relates to a safety monitoring and early warning system for a hydrogen refueling station. The safety monitoring and early warning system comprises a hazard source monitoring unit, a transmission analysis unit and a monitoring alarm unit, the hazard source monitoring unit is used for monitoring the environment of each monitoring point preset in the hydrogen refueling station in real time, and monitored environment data is sent to the monitoring alarm unit through the transmission analysis unit; and the monitoring alarm unit is used for pre-judging the operation safety condition of the hydrogen refueling station according to the monitored environment data, and giving an alarm when the environment data exceeds a preset threshold value. According to the characteristics of hydrogen fuel and the process requirements of the hydrogen refueling station, environmental factors such as combustible gas, temperature, pressure and humidity are monitored and alarmed systematically, and the safety of the hydroge
