Automatic window breaker is an escape device installed on the window of the car to automatically hit the glass burst, so that in the event of a fire, terrorist attack and other emergency situations, the passengers in the car can quickly escape from the window. The so-called fully intelligent glass breaker, the premise is to have glass breaking equipment, and then the central control system intelligently controls these glass breaking equipment to achieve the expected management effect. The requirements for glass breaking equipment are even higher, such as special requirements for materials (planned for fire protection): the connecting wire must reach a certain ignition point to be damaged. Command transmission or use wireless transmission to transmit commands (wireless transmission shortcomings: distance limitation) , To ensure that the instructions issued by the central system can be transmitted to the equipment, the shell of the equipment has a strong anti-strike ability and structure, to prevent accidental damage is the failure of the broken glass equipment, and a backup independent power supply system to prevent it in the event of a power failure. The normal glass breaking effect of the equipment should be simple and easy to use in operation. There is manual control and the actual environmental control of glass breaking. This can connect the relevant trigger to the central controller, such as a fire, this time There is a low-temperature temperature trigger. The trigger detects the preset temperature and can automatically break the glass before it receives the command from the center.
