Description

Fire notification device and system

The invention relates to a notification device and system; specifically, the invention relates to a fire notification device and system.

When a fire occurs, whether it can be notified as soon as possible and enter the rescue at the golden rescue time is related to whether it has caused major casualties and the survival rate of the rescued. If people rely on people to actively discover the occurrence of a fire, they may not be heard because the call for help is too weak, or they need to wait until the fire is violent to detect it. They often miss a good rescue opportunity, and various types of smoke detection and other automatic fire detection systems are produced.

However, the manual notification may not be able to be expressed smoothly due to too much confusion, or the rescuer may not be able to lead the rescuer to the correct location because of the unfamiliar site address. There may be a risk of delaying the time of disaster relief, so an automatic notification system is necessary. However, the telephone loop of the automatic notification system at the scene of the fire may also be destroyed by the fire. Therefore, it is an important research direction in the technical field that how to ensure that the fire information can be quickly and surely transmitted to the rescue center.

FIG. 1 is a schematic diagram of a conventional fire notification device. After the fire notification device receives the warning message sent by the trusted switchboard, the fire notification device passes the public switched telephone network (Public Switched Telephone Network (PSTN) is notified to the fire station by voice notification. However, if the original telephone circuit is burnt due to the high temperature of the fire, it will result in no immediate notification to obtain rescue.

The purpose of the present invention is to provide a fire notification device, which can ensure that the fire information is transmitted to the rescue center without leakage.

The fire notification device includes a control unit, a data unit and a voice unit. The control unit is coupled to the data unit and the voice unit, and is connected to the fire alarm host and the backup message generating module through the first transmission channel and the second transmission channel, respectively. After receiving the warning message sent by the fire alarm host, the control unit generates a notification message, and controls the data unit and the voice unit with the voice unit in a time-multiplexing manner, and controls the backup message generation module to perform the backup notification.

With the fire notification device of the present invention, even if the telephone circuit of the voice notification is damaged due to the fire, the fire information can be transmitted to the rescue center without leakage through the backup notification method.

Another object of the present invention is to provide a fire notification system that can ensure that fire information is transmitted to the rescue center without leakage.

The fire notification system includes a fire notification device, a fire alarm host, and a backup message generating module. The fire notification device includes a control unit, a data unit, and a voice unit. The control unit is coupled to the data unit and the voice unit, and is connected to the fire alarm host and the backup message generating module through the first transmission channel and the second transmission channel, respectively. After receiving the warning message sent by the fire alarm host, the control unit generates a notification message, and controls the data unit and the voice unit to perform a voice notification in a time-division multiplexing manner, and controls the backup message generation module to perform a backup notification.

With the fire notification system of the present invention, even if the telephone circuit of the voice notification is If it is damaged due to the disaster, the fire information can still be transmitted to the rescue center without notice.
