Abstract: The safety status of LNG tank vehicle is monitored in real time by using a particular decision-tree algorithm. The Data acquisition system for the algorithm consists of 8 heterogeneous sensors installed on the LNG tank vehicle, which includes a gas sensor, a temperature and a humidity sensor, a pressure sensor, a liquid level sensor, an accelerometer, an angle sensor, and a door-switch sensor. Some data sets of different running modes of the tank vehicle were used to training the decision-tree, and the others were used to evaluate the status of the vehicle. A simulation system was also established to experimentally verify the accuracy of the algorithm and the results of the experiments show that the monitoring system is good enough for practice usage.


Keywords: Multi-sensors, Decision tree algorithm, LNG tank vehicle, Safety status.
