The present invention relates to a sprinkler device, and more particularly, a sensor that can sense the temperature inside each sprinkler, and can check itself whether the sprinkler is broken, and locally at the location of the fire The present invention relates to a fire sprinkler device and a control method of the sprinkler installed in various places to centrally control the sprinkler installed in various places to more effectively respond to a fire.

In general, sprinkler (sprinkler) is installed on the ceiling inside the building is a fire-fighting equipment that is extinguished by spraying extinguishing fluid, such as water when a fire is detected. The head (H) of the conventional sprinkler, as shown in Figure 1, the digestive fluid outlet (1) connected to the digestive fluid supply pipe by a pipe connecting socket, and the O-ring-shaped body extending downward from the outer peripheral surface of the extinguishing fluid outlet (1) ( 2), a fire extinguishing liquid diffusion plate 6 horizontally coupled to the lower outer circumferential surface of the O-ring body 2, a discharge valve 3 for blocking the extinguishing liquid jet port 1, the discharge valve 3 and the body (2) It comprises a trigger 4 which holds the discharge valve 3 between lower parts, and a thermal fuse F provided in the trigger 4.

As can be seen from FIG. 2, the thermal fuse F is a hollow drum-type casing 11 and a low-temperature molten metal 13 filled in the casing 11 and maintaining a solid state at room temperature. And, the lower portion is supported in the cold melt 13 and the upper portion has a working pin 12 protruding outward the upper portion of the case (11). When a fire occurs and the room temperature increases, the low-temperature melt 13 (eg, lead) of the thermal fuse F melts to a liquid state, and the operation pin 12 sinks into the molten lead. Therefore, when the balance of supporting the discharge valve 3 of the trigger 4 is broken, the discharge valve 3 opens the extinguishing liquid ejection port 1 and the extinguishing liquid is injected.

Another conventional sprinkler of the type uses a glass ampoule filled with a thermally expandable gas instead of the low temperature lead type thermal fuse. When a fire occurs, the gas in the glass ampoule expands and the glass ampoule is destroyed, thereby reducing the support force of the discharge valve. As a lossy structure, its operation principle is not very different from that of the low-temperature lead thermal fuse.

The conventional sprinkler using such a low temperature lead fuse or thermally expanded glass ampoule has a structure in which the fuse or glass ampoule reacts directly with actual fire heat, so that even if a fire occurs, the room temperature may be reduced to the melting point of the low temperature lead or the glass ampoule expansion breakdown temperature. Since the sprinkler does not work until the end, there is a problem that the response to the initial fire is very late.

In addition, firefighting equipment such as sprinklers are installed in most buildings today, but because they are prepared for emergency situations such as fires, most of them are left unused for a long time due to no fire. There is a fear that a part of the circuit is damaged, in this case there is a problem that becomes useless in the event of a fire. In order to solve this problem, the operation health of each sprinkler should be tested from time to time, but it is not easy to test a number of sprinklers fixed on the ceiling from time to time.

In addition, the fire is most often started in a local place, so only the sprinkler of the place where the fire originated works, and in general, the sprinkler of an adjacent room does not work, so the fire is moved to an adjacent room. It can't be prevented from spreading.

In order to solve this problem, the sprinkler apparatus and system as shown in FIGS. 2 to 6 have been developed by the applicant. FIG. 3 is a view showing a cross section of the improved sprinkler apparatus shown in Korean Laid-Open Patent Publication No. 2001-0082794, and FIG. 4 is a view showing a cross section of a thermal fuse used in the sprinkler apparatus of FIG. FIG. 5 is a view showing a cross section of the improved sprinkler apparatus shown in Korean Laid-Open Patent Publication No. 2001-0102616, and FIG. 6 is a view showing a cross section of an ampoule used in the sprinkler apparatus of FIG.

In addition, the outer circumferential surface of the case 11 has a coil-shaped heat transfer heater 14 having one side terminal connected to the energization contact portion 10 and the other side terminal connected to the positive electrode conductor 8 via the low temperature molten metal 13. The outer circumferential surface of the heat transfer heater 14, that is, the outermost outer circumferential surface of the case 11 is coated with a corrosion resistant and insulating coating film 15 to protect the heat transfer heater 14.

Will be determined. To this end, a one chip microcontroller (“microcom”) is required.

Will open.

However, in order to operate the sprinkler device, there is a cumbersome point that a separate temperature sensing unit must be installed at a separate location.

FIG. 7 is a view showing a cross section of the thermal fuse used in the sprinkler apparatus of the present invention, FIG. 8 is a view showing a plane of the thermal fuse of FIG. 7, and FIG. 9 is a view showing a bottom surface of the thermal fuse of FIG. 7. 7 to 9, unlike the conventional configuration, the present invention includes a first and second conductors 8 and 8a different from each other, and includes a thermocouple configured to be in contact with each other. The portion where the first conductor 8 and the second conductor 8a are connected becomes the temperature measuring portion T, and the temperature can be sensed at the temperature measuring portion T according to the principle of the thermocouple. The first conductor 8 is connected in series with the heat transfer heater 14, and the second conductor 8a is connected with a power source. Depending on the connection position of the first conductor 8, the operation pin 23 may be a conductor or a non-conductor.

The first conductor 8 and the second conductor 8a use a thermocouple metal lead wire capable of supplying power to the electric heater 14 while functioning as a thermocouple, and the first conductor 8 and the second conductor 8a. The temperature measuring part (T) which meets) is exposed to the atmosphere, thereby minimizing heat leakage and inflow due to the peripheral device of the thermal fuse (F) to have a sensitive temperature response characteristic. In particular, by minimizing the temperature (T) of the thermocouple to a few mg or less, it is able to react immediately to the room ambient temperature sensitively.

It is preferable to coat the cover 15 on the outside of the case 11 using an insulating material such as an enamel for preventing corrosion, within a range that does not interfere with the heat conduction. The heat transfer heater 14 has one end connected to one terminal of the power supply, the other end connected to the first conductor 8 of the thermocouple including the first conductor 8 and the second conductor 8a, and the second conductor ( 8a) is connected to the bidirectional input / output control port of the control unit microcomputer.

The operation of temperature detection, input / output, heating, and self-diagnosis of the sprinkler device will be described with reference to FIG. 28 simultaneously.

[Temperature Detection and Input Operation]

In the temperature measurement part T, an electromotive force between the first conductor 8 and the second conductor 8a, which is proportional to temperature, is generated, and when applied to the control unit (not shown) micom according to the electromotive force, the microcomputer generates this electromotive force. The value is directly amplified and the signal analyzed to determine if the temperature limit is exceeded. If it is determined that there is a fire exceeding an appropriate temperature limit, the input port connected to the first conductor 8 and the second conductor 8a is switched to the output port.

At this time, since the electromotive force value generated in the temperature measurement part T is very low, the internal resistance of the heat transfer heater 14 connected in series with the first conductor 8 and the second conductor 8a is not heated. Therefore, the power consumed by the electrothermal heater 14 internal resistance by the electromotive force of the temperature measuring part (T) is negligible. In order for the low electromotive force generated by the temperature measuring part T to be transferred to the microcomputer without loss, the input impedance of the microcomputer should be several ㏁ or more. Therefore, the low electromotive force generated in the temperature measurement part T is transmitted to the microcomputer input terminal having an infinite resistance value of several orders of magnitude or more after passing the internal resistance of the electrothermal heater 14 of several tens of Ω connected in series. Therefore, the internal resistance value of the electrothermal heater 14 of several tens of ohms is ignored, and the electromotive force value is transmitted to the microcomputer without loss. This process is the temperature detection operation through the input port.

[Output and heating operation]

In the heating operation through the output port, the heating operation proceeds when a signal output from the microcomputer is applied to the internal resistance of the electrothermal heater 14 through the thermocouple metal lead wire. At this time, the electromotive force generated in the thermocouple is several kilowatts or less, and the internal resistance is also very low, 1Ω or less, so that the heating voltage and current are not affected. Thus, the electrothermal heater 14 is heated without particular loss by the thermocouple.

The current applied to the first conductor 8 and the second conductor 8a by switching to the output port heats the heat transfer heater 14. As a result, the low-temperature melting conductor 13 melts and the operation pin 12 As it sinks downward, the discharge valve 3 is opened and the extinguishing liquid is ejected.

[Self fault diagnosis operation]

Since the electric heater 14 and the first conductor 8 and the second conductor 8a constituting the thermocouple are connected in series with each other, if a physical breakdown such as disconnection or poor connection occurs, the thermocouple The electromotive force is lost in the temperature measuring part (T) to change. Since the lost electromotive force signal is transmitted to the microcomputer, it is possible to determine whether the electric heater 14 is properly connected or well connected, and thus the self-failure diagnosis operation is possible.

[Automatic response operation]

Even if the electric heater 14 is not operated due to a failure, a power failure, or the like, when the ambient temperature increases, the low-temperature melt 13 melts itself, thereby discharging the extinguishing liquid, thereby functioning as an automatic reaction safety device.
