[0002] As a kind of permanent transport equipment running along rigid track, elevator is designed to serve specific floor in building. However, in the process of long-time running of elevator, elevator failure occurs from time to time due to equipment aging and other factors. Among them, the most common type of failure is stop running, that is, elevator stops suddenly when running to the position between floors, resulting in passengers being trapped and unable to escape. At this time, trapped personnel need to contact external personnel for rescue. Therefore, alarm device is usually equipped in elevator, passengers only need to press the button to transmit the rescue information to property management department responsible for elevator management, and then professional personnel are contacted by property management department to come to rescue. However, some property units lack corresponding emergency management measures, resulting in that rescue signal cannot be handled in time, and trapped personnel are thus detained in elevator for a long time, which has great safety hidden danger. In addition, elevator will accelerate the flow of internal air during running, and once the elevator stops, the flow of internal air will be weakened, which may cause passengers to feel suffocating and irritable, and thus may trigger irrational behavior such as prying elevator door, which also hides safety hidden danger, so a device is needed to solve the above problems.
