The present invention relates to a train fire detection device using a digital temperature controller that can detect a fire easily and extinguish it early by operating a fire indication lamp installed in an engine control box.

In general, a locomotive or various trains that use oil are not provided with a device for detecting a fire, or a device that stops the engine only when the temperature of the engine oil is higher than a specified value by a sensor whose temperature is specified. Therefore, it is difficult to test a vehicle fire detection system by a simulation test before a fire occurs, which causes considerable physical and human loss in the event of a fire.

In addition, since the fire indicator lamp for the engine of each vehicle is not provided for each vehicle, the vehicle is frequently changed when the vehicle is organized, so it is not easy to detect the fire for each vehicle.

Accordingly, the present invention is to solve the above problems, in the train to drive the engine using oil installed in the cab and the engine control after detecting the fire by a fire sensor connected to the digital temperature controller installed in each train It is an object of the present invention to provide a train fire detection device using a digital temperature controller that can detect a fire easily and extinguish it early by operating a fire indication lamp.

The present invention for achieving the above object is a digital temperature controller installed in each vehicle; Fire detection means connected between a sixth terminal and a seventh terminal of the digital temperature controller and detecting a temperature above a set temperature; A relay which is connected between the first terminal of the digital temperature controller and the ground and is excited by a power source from the first terminal when the fire detection means detects a temperature higher than a set temperature; Contact a of the relay for turning on the contact point of the relay when the relay is excited and lighting the cab fire indication lamp and the vehicle-specific fire indication lamp; The a contact is turned on while being connected between the DC power supply and the contact a of the relay, and the diode is configured to apply power only to the fire indicator lamp for each vehicle of the vehicle.

According to the present invention configured as described above, in a train for driving an engine using oil, a fire display lamp installed in a cab and an engine control unit after detecting a fire by a fire detection sensor connected to a digital temperature controller installed in each train is installed. This makes it easy to detect a fire and to extinguish the fire early.

2 is a train fire detection circuit diagram using a digital temperature controller installed in each vehicle, wherein the fire detection circuit diagram is a digital temperature controller 11 installed in each vehicle; A fire detection unit 10 connected between a sixth terminal and a seventh terminal of the digital temperature controller 11 and detecting a temperature higher than a set temperature; A relay 12 connected between a first terminal of the digital temperature controller 11 and a ground and excited by a power source from the first terminal when the fire detection unit 10 detects a temperature higher than a set temperature; Contacts a and 16 of the relay for turning on the ignition fire indication lamp 15 and the vehicle-specific fire indication lamp 13 by turning on the contact state of the relay 12 when it is excited; The a contact 17 is turned on while being connected between a DC power supply and a contact 17 of the relay, and is configured as a diode 14 for applying power only to the vehicle-specific fire indicator lamp 13 of the vehicle.

First, when the fire detection apparatus of the present embodiment is operated by a DC power source, for example, 24V, when the DC power source is input to the third and fourth terminals of the digital temperature controller 11, the digital temperature controller 11 may be configured to be first. The fire detection sensor 10 installed between the third and fourth terminals is operated.

Thereafter, when the set temperature or more is detected by the fire detection sensor 10, the digital temperature controller 11 sets the voltage for the detected temperature from the fire detection sensor 10 through the internal D / A converter. By outputting to terminal 1, the relay 12 connected between the terminal 1 and ground is operated.

In this case, the contacts a and 16 of the relay 12 are turned on so that the DC power is applied to a circuit composed of the diode 14, the cab fire display lamp 15, and the contact 16, and thus the cab. The fire display lamp 15 is turned on, and the direct current power is applied to a circuit composed of the contact 17 and the fire display lamp 13 for each vehicle, so that the fire display lamp 13 for each vehicle is turned on.

In addition, in the case of diesel cars, connection is possible for each vehicle, and the fire display lamp of the vehicle is turned on by the fire occurrence signal from the fire detection sensor of each vehicle, and the fire display lamp of the cab is turned on. When the fire occurs in a predetermined vehicle, the diode 14 does not turn on the fire display lamp of another car, and only the fire display lamp of the fire vehicle is turned on, so that the corresponding fire vehicle can be easily found.

On the other hand, the reference numerals written in the components of the claims of the present application to facilitate the understanding of the present invention, and are not written in the intention to limit the technical scope of the present invention to the embodiments shown in the drawings.
