[0002] The safety and reliability of public transportation maintains the safety of the public and the stability of the society. Today, with the gradual advancement of urbanization, the focus of the public transportation system is on the layout of the transportation capacity, and at the same time, safety is placed in an increasingly important position. From the perspective of comfort, fully enclosed air-conditioned vehicles have become the first choice for public transportation. During the operation of vehicles, the sources of passengers are complex, and public transportation vehicles are prone to fire and other dangers during operation. Due to the large number of passengers, when a disaster occurs , because the panic cannot be properly dealt with in time, causing the loss of vehicles and passengers, bringing great pain to many families, and also causing huge losses to the country. The existing public transport fire extinguishing devices are all after the disaster. , and the current public transportation cannot predict whether the passengers on board themselves and their luggage carry dangerous items, and there is no early warning and the ability to eliminate disasters in the bud. Low, low reliability and other disadvantages
