In detail, when a fire alarm occurs, the fire alarm host C is used to output a fire alarm notification to the fire host F through a first communication line of the fire alarm host C, where the fire alarm host C is, for example, an R type fire alarm switchboard or a P type fire alarm receiver. switchboard. This means that the fire alarm host C outputs the fire alarm notification to the fire host F through the Public Switched Telephone Network (PSTN) and the first communication line, where the first communication line is, for example, a telephone line.

The first temperature sensor 1 is used to sense the first communication line of the fire alarm host C (that is, the line connecting the fire alarm host C and the fire host F as shown in FIG. 1), and the first temperature sensor 1 is better It senses the temperature of the first metal ground layer of the first communication line, and uses the sensed temperature of the first metal ground layer as a first temperature.

However, the present invention Not limited to this. The first temperature sensor 1 senses the temperature of the first metal ground layer L. For example, a part of the insulation layer of the coaxial cable (ie, the outermost insulation layer shown in FIG. 3) is removed to make a Part of the first metal ground layer L is exposed as shown in FIG. 3, so that the first temperature sensor 1 can sense the temperature of the first metal ground layer L.

In detail, when the first temperature sensor 1 is an infrared temperature sensor, the infrared temperature sensor may be adjacent to the first metal ground layer L provided on the first communication line, and the infrared temperature sensor and The distance between the first metal ground layer L is less than or equal to the maximum sensing range of the infrared temperature sensor; when the first temperature sensor 1 is a resistance thermometer, the resistance thermometer may be the first communication line On a metal ground layer L, and the resistance value of the resistance thermometer will increase as the temperature of the first metal ground layer L rises, and become smaller as the temperature of the first metal ground layer L drops, the resistance thermometer can be based on the resistance The value gets the first temperature.

Please continue to refer to FIG. 1. The processor 3 is communicatively connected to the first temperature sensor 1 to receive the first temperature, and the processor 3 determines whether the first temperature is higher than a preset temperature. A communication line) the critical temperature of the fire, and when the processor 3 determines that the first temperature is higher than the preset temperature, a warning notification is generated. That is, in the case of no fire in the wire, the first temperature should be normal temperature or the working temperature of the first communication line in normal operation. Therefore, when the processor 3 determines that the first temperature is higher than the preset temperature, it indicates that a wire fire or even a fire may occur, and the processor 3 generates a warning notification accordingly. The processor 3 is, for example, a microprocessor, and the present invention is not limited thereto.

In addition, the processor 3 is further electrically connected to an emergency power supply device, so that the processor 3 can still have a backup power supply in the event of a fire. The emergency power supply device is, for example, a generator or an uninterruptible power system (UPS). Or batteries, etc., the present invention is not limited to this.

That is, in the absence of a fire in the wire, the second temperature should be normal temperature or the working temperature of the second communication line in normal operation. Therefore, when the processor 3 judges that the second temperature is higher than the preset temperature, it indicates that a wire escape or even a fire may occur, and the processor 3 generates a warning notification accordingly and can send a warning notification to the fire host F through the fire alarm host C , So that the fire host F can be notified as soon as possible in the event of an electric wire escape occurrence or imminent occurrence.

Please continue to refer to FIG. 2, where the first temperature sensor 1 and the second temperature sensor 2 preferably simultaneously sense the temperature of the first communication line and the temperature of the second communication line, respectively. According to this, when the temperature of the first communication line is too high, the processor 3 can send a warning notification through the backup communication device 5; and when the temperature of the second communication line is too high, the processor 3 can send a warning through the fire alarm host C Alert notice.

In addition, when the first temperature sensor 1 detects that the first temperature of the first communication line is higher than the preset temperature, and the second temperature sensor 2 also detects that the second temperature of the second communication line is higher than the preset temperature , The processor 3 can control the fire alarm host C and the backup communication device 5 to output the warning notice to the fire host F in the manner of Code-Division Multiplexing (CDM), where the alarm notification output by the fire alarm host C preferably includes The second communication line is abnormal, and the warning notification output by the backup communication device 5 preferably includes the first communication line abnormality message. In other words, when the fire alarm host C and the backup communication device 5 need to output a warning notification at the same time, and the warning notification is a digital signal, the warning notification output by the fire alarm host C can be output in the form of a first code; the backup communication device 5 The output warning notice can be output in the form of a second code. Accordingly, the fire host F can distinguish the received warning notice according to the first code and the second code.

In addition, the processor 3 can also control the fire alarm host C and the backup communication device 5 to output the warning notification to the fire host F in a time-division multiplexing (TDM) manner, and the present invention is not limited to this.

In addition, the fire alarm host C preferably includes a fire alarm detector to detect whether there is a fire in its setting environment. When the first temperature measured by the first temperature sensor 1 is higher than a working temperature, the fire alarm detector detects When the setting environment is in a non-fire alarm state (that is, the state of the setting environment of the fire alarm detector is a normal state), the processor 3 outputs a communication line abnormality notification.

In detail, when the first temperature of the first communication line is higher than the working temperature, and the fire alarm detector detects that its setting environment is in a non-fire alarm state, it means that the first temperature is higher than the working temperature is not caused by the fire alarm. Therefore, the processor 3 outputs a communication line abnormality notification, and the communication line abnormality notification includes a message that the temperature of the first communication line is abnormal to remind the fire host F that the temperature of the first communication line is abnormal.

In summary, according to the warning system disclosed in one or more embodiments of the present invention, the communication line of the fire alarm host can be prevented from being affected by the fire and unable to transmit the warning notification to the fire host. In addition, according to the warning system disclosed in one or more embodiments of the present invention, it is possible to avoid the situation that the warning notification cannot be transmitted to the fire host when the communication line of the fire alarm host or the backup communication device is burned, and the communication line is burned.
