Table 1 and Table 2 are tables for explaining an embodiment of a method for determining the state of the inside of the panel, Table 1 shows that the door detection signal (s_door) output from the door sensor 14 indicates that the door of the panel is closed Table 2 is a table for explaining the determination method in the case, Table 2 is a table for explaining the determination method when the door detection signal s_door output from the door sensor 14 indicates that the door of the panel is open.

Referring to Table 1 and Table 2 will be described a method for determining the state inside the panel in the fire detection apparatus and system of the present invention.

First, referring to Table 1, when the door of the panel is closed, it is very unlikely that the flame sensor 11 detects the light introduced from the outside. Therefore, in this case, when one of the light detection signal s_light, the smoke detection signal s_smoke, and the temperature detection signal s_tmp is activated, the state inside the panel is regarded as a caution state, and the light detection signal s_light, smoke When two of the detection signal (s_smoke) and the temperature detection signal (s_tmp) are activated, the state inside the panel is determined as a warning state, and the light detection signal (s_light), the smoke detection signal (s_smoke), and the temperature detection signal (s_tmp) are determined. When all are activated, the state inside the panel is regarded as a fire state.

Next, referring to Table 2, when the door of the panel is open, the probability that the flame sensor 11 detects the light flowing from the outside increases, the light detection signal (s_light) is less reliable. Therefore, in this case, when one of the signals other than the light detection signal s_light, that is, the smoke detection signal s_smoke and the temperature detection signal s_tmp, is activated, the state inside the panel is determined as a caution state. In addition, when both the smoke detection signal s_smoke and the temperature detection signal s_tmp are activated, if the light detection signal s_light is deactivated, the state inside the panel is determined as a warning state, and the light detection signal s_light is detected. If activated, the state inside the panel is regarded as a fire state.

If it is determined that the door of the panel is open, the control unit 20 may inform the central control unit 2 of this.

That is, when any one of the plurality of sensors outputs an abnormal signal, the fire detecting apparatus and system of the present invention determines the state inside the panel as a caution state, and more than half of the plurality of sensors detect an abnormal signal (that is, smoke is generated). Signal detected, or that the instantaneous temperature increase rate has exceeded a predetermined reference value, is determined as a warning state, and when a plurality of sensors output an abnormal signal, the state inside the panel is fired. It can be judged as a state.

In addition, the state inside the panel may be determined not only by the number of sensors generating the abnormal signal, but may be weighted according to the type of sensor, and then the state inside the panel may be determined based on the output of the weighted sensor. have. For example, when a higher weight is given to a temperature sensor, even when only a temperature sensor outputs an abnormal signal, it may be determined as a warning state.

If it is determined that the state of the panel is a caution state or a warning state, the fire detection device and system of the present invention may display the operator so that the operator can know it through the display unit 50 and / or a separate warning device (not shown). At this time, if it is determined that the warning state, the operator can be advised to pay more attention. For example, if it is determined that the state of the panel is in a caution state, a lamp or the like is notified to an operator, and if it is determined that the state of the panel is in a warning state, the worker is notified of a warning state through a siren or the like as well as a lamp. I can inform you. If it is determined that the state of the panel is a fire state, the fire detection apparatus and system of the present invention operates the fire extinguishing device 40 inside the panel.

In the present invention, the operation of determining the state inside the panel may be performed by the control unit 20 inside the fire detection apparatus 100-k or may be performed by the central control unit 2.

When the operation of determining the state inside the panel is performed by the control unit 20, the control unit 20 may transmit the determined state inside the panel to the central control unit 2. In addition, the control unit 20 may operate the display unit 40, the separate warning device (for example, a lamp and / or siren, etc.) and / or the fire extinguishing device 40 by itself, and the central control unit 2 In response to the signal received from the display unit 40, the separate warning device and / or fire extinguishing device 40 may be operated.

When the operation of determining the state inside the panel is performed by the central control unit 2, the fire detection device 100-1, 100- installed in the panels 1-1, 1-2, ..., 1-n. 2, ..., 100-n transmits a light detection signal s_light, a smoke detection signal s_smoke, a temperature detection signal s_tmp, and a door detection signal s_door to the central control unit 2, The central control unit 2 determines the state inside the panel based on the signals, and then displays the display unit 40, the separate warning device (for example, a lamp and / or siren) and / or a fire extinguishing device 40. The control signal for operating the can be transmitted to the fire detection device (100-1, 100-2, ..., 100-n) and / or a separate warning device (not shown).

3 is a view showing an embodiment in which the fire detection device 100-k of the present invention is actually implemented. As illustrated in FIG. 3, the fire detection apparatus 100-k of the present invention may be implemented in a set form in which each component is installed in the case. In FIG. 3, 40 denotes a fire extinguishing device, and sensors (eg, flame sensor 11, smoke sensor 12, temperature sensor 13, door sensor 14, etc.) in a portion indicated by identification number 10. This may be installed, the control unit 20 and the like may be disposed in the portion indicated by the identification number 20. In addition, the display unit 50 may be separately manufactured to be recognized from the outside of the panel. Similarly, the communication unit 20 may be installed inside the case shown in FIG. 3, but may be separately manufactured so as to be installed outside the panel in order to smoothly transmit and receive signals.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
