BEST MODES FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows the configuration of a system for automatically opening an emergency gate according to a preferred embodiment of the present invention.
Referring to FIG. 1, the automatic emergency gate opening system of the present invention includes an automatic opening unit 100 for receiving an emergency signal and then opening an emergency gate (not shown), and a management unit 200 for detecting an emergency state such as a fire and outputting an emergency signal to operate the automatic opening unit 100.
According to the present invention, the automatic opening unit 100 is installed to stairs or an exit of a building where an emergency gate is located, while the management unit 200 is installed in a central administration room or a control room for monitoring fire or controlling overall system. Specifically, the automatic opening unit
100 is electrically connected to an emergency exit light 10 prepared adjacent to the emergency gate, for example above the emergency gate. As well known in the art, the emergency exit light is a lamp for guiding people to an exit when a fire or a power failure occurs, and it is essentially installed together with the emergency gate. According to the present invention, since the automatic opening unit 100 is electrically combined to the emergency exit light 10 near the emergency gate, there is no need of any additional private line construction, as described below. Though it is described that the automatic opening unit 100 is connected to the emergency exit light 10 in this embodiment, the automatic opening unit 100 may also be connected to a fire alarming lamp or other fire fire-fighting equipments positioned near the emergency gate, not limited to that case. Hereinafter, the emergency exit light, the fire alarming lamp and the fire-fighting equipments installed adjacent to the emergency gate are inclusively called "a remote fire electricity line terminal" in this specification and the appended claims. Such a remote fire electricity line terminal is connected to an emergency power supply 20 in the central administration room through a wire and supplied with power. This wire is defined as "a fire electricity line 30" in this specification and the appended claims.
The management unit 200 is installed so that it is electrically connected to the emergency power supply 20 in a region where a manager resides such as the central administration room, more specifically to the fire electricity line 30.
The automatic opening unit 100 includes a first central controller 110 for controlling each component and outputting an emergency gate opening control signal according to an emergency control signal received from the management unit 200, a first filter/composition unit 120 connected to the fire electricity line 30 for separating a power and a data signal from a received power line signal or coupling the power and the data signal, a first communication module 130 for receiving a data signal transmitted from the first filter/composition unit 120, and an opening unit controller 140 for receiving the emergency gate opening control signal from the first central controller 110 and outputting an emergency gate operating signal.
Reference numeral 150 denotes a first battery for continuously applying an electric current to the automatic opening unit 100 even though an electric power is interrupted. Reference numeral 160 denotes a first manual operating unit prepared for manual opening of the emergency gate. Reference numeral 40 denotes an emergency operating unit for receiving the emergency gate operating signal from the opening unit controller 140 and then operating the emergency gate to be opened. Reference numeral 50 denotes a monitor for monitoring an opening state of the emergency gate.
The management unit 200 includes a second central controller 210 for controlling each component and receiving a detect signal to output an emergency control signal according to the detect signal, a second communication module 220 for transmitting a data signal output from the second central controller 210, a signal receiving unit 230 for receiving a signal transmitted when an emergency state such as a fire is detected by an automatic detector 60, and a second filter/composition unit 240 for coupling a data signal output from the second communication module 220 with a frequency of a power line to compose a power line signal.
In addition, the management unit 200 may further include a panel 250 in which an alarm lamp (not shown) for visually showing the generation of an emergency state or an opening state of the emergency gate or a speaker (not shown) for generating an audible alarm.
Besides, reference numeral 260 denotes a second battery for continuously supplying an electric current to the management unit 200 even when an electric power is interrupted, and reference numeral 270 denotes a second manual operating unit used for manual operation of the emergency gate.
In addition, the automatic detector 60 may include various kinds of sensors capable of detecting a fire or smoke together with a fire detect sensor. Now, an operation of the automatic emergency gate opening system according to the present invention constructed as above is described in detail with reference to
FIG. 2.
First, the second central controller 210 of the management unit 200 keeps determining whether a detect signal informing of a fire is received (step S300). This detect signal is generated when the automatic detector 60 senses a fire or smoke. In other words, when a fire occurs, the automatic detector 60 outputs a fire detect signal, and this detect signal is received in the signal receiving unit 230 and then transmitted to the second central controller 210.
Subsequently, if it is determined that the detect signal is received, the second central controller 210 outputs an emergency control signal to operate the emergency gate (step S310). Preferably, the second central controller 210 may transmit a separate output signal to the panel 250 so as to turn on the alarming lamp or generate an alarm through a speaker.
The output emergency control signal is transmitted through the fire electricity line 30 in the step S320. Specifically, the data signal output from the second central controller 210 is sent to the second filter/composition unit 240 through the second communication module 220, and the second filter/composition unit 240 couples the data signal with a power line frequency for the purpose of Power Line Communication
(PLC). As well known in the art, the PLC exchanges data at a frequency having a much higher bandwidth (l~30Mhz) than a frequency required for exchanging power (about 60Hz) among the frequency bandwidth in the power line. Though the PLC generally shows much loss of data since it is very weak to noise, the fire electricity line used in the present invention may be protected from electronic equipments such as an air conditioner or an audio through which strong electricity flows since it is buried in a wall of a building, and it may be effectively used without noise or data loss since it is installed at a relatively short distance. The power line signal composed as above is transmitted to the automatic opening unit 100 electrically connected to the remote fire electricity line terminal such as the emergency exit light 10 through the fire electricity line 30.
The transmitted power line signal is again separated into the power and the data signal at the first filter/composition unit 120. The separated data signal is also transmitted to the first central controller 110 through the communication module 130.
The first central controller 110 determines whether the emergency control signal is received (step S330). If the emergency control signal is received, the first central controller 110 outputs an opening control signal for opening the emergency gate and then transmits the opening control signal to the opening unit controller 140 (step S340).
The opening unit controller 140 determines whether the opening control signal is received from the first central controller 110 (step S350). If received, the opening unit controller 140 outputs an emergency gate operating signal for opening the emergency gate (step S360).
The emergency gate operating signal is transmitted to the emergency gate operating unit 40, and then the emergency gate operating unit 40 is operated to open the emergency gate (step S370). According to the present invention, the opening state of the emergency gate is continuously monitored and then informed to a manager in the central administration room in which the management unit 200 is positioned. In more detail, the opening state of the emergency gate is detected by the monitor 50, and a monitoring signal generated by the detection is transmitted to the opening unit controller 140.
If the opening gate controller 140 determines that the emergency gate is abnormal such as an improper opening according to the monitoring signal, this fact is informed to the first central controller 110, and thereby the first central controller 110 outputs a disorder signal. The output disorder signal is converted into a data packet in the first communication module 130, and then coupled with a power line frequency in the first filter/composition unit 120. Then, the composed power line signal is transmitted to the management unit 200 through the fire electricity line 30 connecting the remote fire electricity line terminal 10 and the emergency power supply 20 so that the second filter/composition unit 240 separates and extracts the data signal. The separated data signal is again transmitted to the second central controller 210 through the second communication module 220. The second central controller 210 outputs an alarm signal to the panel 250 in order to inform of the abnormal state of the emergency gate to the manager by, for example, blinking the alarming lamp in the panel 250 or generating an alarm through the speaker.
According to the present invention, the emergency gate may be opened manually. This manual opening of the emergency gate may be performed using the management unit 200 in the central administration room in a remote plate or by the automatic opening unit 100 positioned near the emergency gate. First, if a manager positioned near the management unit 200 operates the manual operating unit 270, the second central controller 210 outputs an emergency gate manual opening signal. This output signal is, as mentioned above, transmitted through the second communication module 220, composed with a power line frequency in the second filter/composition unit 220, and then transmitted to the automatic opening unit 100 through the fire electricity line 30.
Subsequently, the data signal separated in the first filter/composition unit 120 of the automatic opening unit 100 is received to the first central controller 110 through the first communication module 130, and the first central controller then instructs to open the emergency gate by outputting the emergency gate opening control signal as described above.
On the other hand, to open the emergency gate by use of the first manual operating unit 160 positioned adjacent to the automatic opening unit 100, the first central controller 110 transmits an opening control signal to the opening unit controller 140 as well as transmits an emergency gate opening state signal to the management unit 200 through the first communication module 130. The opening state signal is composed into a power line signal in the same way as described above and then transmitted to the management unit 200 through the fire electricity line 30. The transmitted power line signal is processed in the second filter/composition unit 240 so that the data signal is separated from the power line signal. The separated data signal is received in the second central controller 210, and a state displaying signal is output to the panel 250 therefrom. Thus, the panel 250 makes the opening state of the emergency gate be visually checked by a manager by means of, for example, turning on the emergency exit light. The automatic emergency gate opening system according to the present invention may also include first and second batteries 150 and 260 so that the communication is ensured through the fire electricity line 30 using the battery power though the emergency power supply 20 is blocked due to the interruption of electric power.
INDUSTRIAL APPLICABILITY
The automatic emergency gate opening system according to the present invention controls the opening of the emergency gate by use of an existing fire electricity line without installing any separate private line, so the system may be constructed and installed at a low cost. In fact, the fire electricity lines already constructed in the existing building is connected from the emergency power supply in the central administration room to the point of each emergency gate through a power line network. Thus, the emergency gate opening system of the present invention may manage the opening of the emergency gates in a bundle by a centrally concentrated way without constructing a separate private network.
The present invention has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
