Automatic glass crushing emergency escape and alarm system and traffic vehicle

Abstract

The invention relates to an automatic glass crushing emergency escape and alarm system and a traffic vehicle. The automatic glass crushing emergency escape and alarm system comprises glass crushing devices used for crushing glass, independent control devices and centralized control devices. The independent control devices are used for receiving signals and controlling detonation of the glass crushing devices. The independent control devices are connected with the glass crushing devices. The centralized control devices are connected with the independent control devices through a communication bus or a conductive wire. The independent control devices and / or the centralized control devices comprise fault self-diagnosis systems which can conduct fault diagnosis on electric ignition circuits in real time. The automatic glass crushing emergency escape and alarm system and the traffic vehicle have the advantages that the occurrence of accidents can be sensed automatically, the glass can be crushed automatically, the fault self-diagnosis system can diagnose circuit faults in real time, it is guaranteed that the system is in the working state, and the safety coefficient is high.

Description

technical field [0001] The invention relates to a public transport safety system, in particular to an emergency escape and alarm system for automatically breaking glass and a transport. Background technique [0002] In recent years, vehicle accidents often occur, and secondary injuries after accidents often cause a large number of casualties. For example, when a vehicle falls into a water accident, the vehicle will sink into the water within 2 minutes. After the vehicle falls into the water, a certain water level pressure difference is formed inside and outside the door, so that the possibility of opening the door to escape is almost zero, so breaking the window in this dangerous situation has become the only way to escape. After falling into the water, people will panic, and the probability of escaping by physically breaking the glass is very low. When the vehicle is on fire, etc., the existing method is to use the safety hammer configured on the side window of the vehicle...

AI Technical Summary

Problems solved by technology

[0009] Its device only has the gas generator part, and the shortcoming of the technical scheme without hitting the warhead is that, first, the pressure generated by the gas alone cannot reliably break the glass. During installation, the gap formed between the gas generator and the glass due to manufacturing or assembly work will leak, thereby reducing the gas pressure of the gas generator; second, the ignition tube of the gas generator is generally metal, and when the gunpowder During the explosion, a large number of metal fragments will be shot out to the outside of the broken glass, which may cause fatal injuries to people outside the vehicle

[0010] The disadvantage of the technical solution that includes the impact warhead is: but the warhead has no limit structure. When detonated, the warhead will shoot out to the outside of the glass at a high speed, and at the same time, the metal shell of the ignition tube will explode. The fragments will also shoot to the glass. outside, which may cause greater injury to people outside the vehicle

But the problem that it exists is that when an accident occurs, the main system power supply of the vehicle (such as a car battery, a generator, etc.) will generally be cut off, and the self-explosion system of the side window glass will not be able to self-explode at this time; Long-term turbulence, open circuit, short circuit or poor contact of cables or connectors or thermal resistance wires (such as: cable aging, damage, oxidation of connector contacts, or virtual connections caused by vibration, etc.), the system has failed

However, the heating time of this technical solution is long, and generally takes 10s-20s. In the case of a fire, the 10s-20s time has missed the best escape time, and a high-power power supply is used for heating. It cannot work after power on, and the main circuit has been cut off when the danger occurs
