Provided is an escape passage opening and expanding device used when a bus catches fire. The system can be divided into a firing and detonation monitoring system, a theft and loss preventing monitoring system and a power supply system according to functions. According to spatial arrangement, the system can also be divided into a system outside a box and a system inside the box. When the bus runs, the whole system is powered on and works. When the bus stops, the firing and detonation monitoring system is powered off, and the theft and loss preventing monitoring system is powered on and performs monitoring continuously. Due to the device, when the bus catches fire, a smoke and fire composite sensor can perform detection simultaneously and send a firing signal to a central processor, and therefore the a detonator can be controlled to detonate linear shaped charge, a high-energy-density shaped charge jet is formed, bus doors and window frames are cut, and an escape passage can be opened up and expanded for a driver and passengers. The device can form a barrier-free escaping passage within a microsecond level under the situation that the bus catches fire, and the escaping and rescuing difficult situation caused when the bus catches fire can be eliminated; and a linear shaped charge jet cutter can be scientifically managed.
