The inspection module can perform predictions based on a multilayer sensor algorithm. The multilayer sensor algorithm model is as follows:

[0022] I. Core Assumptions of the Model

[0023] Taking the binary classification prediction of liquid ammonia storage tank leakage risk as an example, the core parameters are set as follows:

[0024] Input characteristics: Select 3 monitoring parameters (numerical type) that are strongly correlated with leakage.

[0025] Pressure inside the storage tank (MPa)

[0026] Tank wall temperature (°C)

The start module activates the monitoring unit for monitoring. The inspection module predicts whether there are leaks in hydrogen, ammonia, and alcohol storage tanks. "Inspection passed" indicates no leaks, while "inspection failed" indicates leaks. The alarm module issues an alarm command upon leak detection. Based on the set period, the status of the storage tanks in the transport vehicles is monitored periodically, and the risk of leaks is predicted. When a leak risk is predicted, an alarm is issued to remind transport personnel to maintain the storage tanks in a timely manner to prevent leaks of hydrogen, ammonia, alcohol, and other media, avoiding accidents such as explosions and poisoning, and improving the safety of transport.
