As shown in Figures 1 to 6 the present invention is a detector 10 is installed on the ceiling of the vehicle interior, the detector 10 is composed of a complex type for detecting the smoke and heat generated in the event of fire by each sensor do.

The heat detection method of the sensor 10 detects heat in a constant temperature detection method that operates when the set temperature is exceeded, and a differential detection method that operates when the temperature rises rapidly above the reference temperature. The smoke sensor is a photoelectric type with a sensitivity of 3.1% (± 0.5-1%).

The detector 10 normally has an interval of about 8 to 9 seconds periodically and the LED is extinguished. When the fire is detected, the LED lamp is turned on. The light turns off or flashes periodically with an interval of about 1.5 seconds.

A fire receiver 20 is installed for each vehicle to determine whether a fire has occurred by discriminating a signal applied by the detector 10 through wires already installed in the vehicle.

When the first fire detection signal is input from the detector, the fire receiver 20 automatically switches to the multi-sensing mode, and continuously analyzes the signal within a predetermined time (adjustable time) and determines two of the three detectors 10. When the fire occurrence signal is input from the above detector 10, it is determined that a fire has finally occurred.

The fire receiver 20 is connected to the train monitoring system terminal device 4 installed in the passenger car through the wiring provided in the vehicle, and the train monitoring system terminal device 4 is the train monitoring system terminal device 4 of the TC vehicle.

The detector 10 receives an input voltage from the fire receiver 20 and transmits a fire, failure, and disconnection signal to the fire receiver 20.

The main circuit controller of the fire receiver 20 analyzes and judges the signal received from the detector to issue its own alarm sound, and drives the relay to transmit to the train monitoring system terminal 4.

In addition, a plurality of LEDs corresponding to the front panel of the fire receiver is turned on through the internal connector of the fire receiver 20.

The fire receiver 20 includes a power switch 21 for interrupting the power supply, an initialization switch 22 for resetting the fire receiver 20, an operation lamp 23 which continuously extinguishes when it is in normal operation, and a detector. The signal between the multi-sensing lamp 24 and the detector 10 and the fire receiver 20, which are turned on when the smoke 10 detects smoke and heat for the first time, is applied through wires already installed in the vehicle.

The parking mode delays the detector's operation for a certain time when the power is turned on and started after parking to prevent fire malfunction due to an increase in the room temperature due to external heat such as in the summer, and automatically resets to the normal mode after 10 minutes in the initializing state. The operation in (22) also restores the normal mode.

Multi-sensing mode reads the signal within 30 seconds after the first input of the fire detection signal and outputs the final fire alarm.

The circuit breakage check confirms the circuit between the detector 10 and the fire receiver 20, and the fault lamp 26 is turned on when the circuit breaks.

The multi-circuit method determines the final fire when two adjacent detectors 10 simultaneously operate as shown in FIG. 3, and determines whether or not there is a fire within 30 seconds.

As shown in FIG. 3, when the first fire signal is first input by one detector 10, the signal is automatically switched to the multi-sensing mode, and through the signals received through the two detectors 10 when the secondary signal is input. Determine if a fire has occurred.
