The present invention relates to a master controller unit for earthquake disaster prevention, and more particularly, it is included in an automatic control system of a building to control and cut off power or combustible materials supplied to various machinery in the building when an earthquake occurs. A device for preventing disasters.

In general, large and small earthquakes occur in various parts of the world, and people who are inside the building are trapped in the building and are injured by fire, explosion, collapse and electric shock due to short circuit. Many. On the other hand, even if people were evacuated by warning of an earthquake in advance, there were many cases of property damage due to short circuits in the machine room, fire, and explosions caused by leaked gas and combustible materials.

On the other hand, the magnitude of the earthquake is an absolute value irrespective of the place where the amplitude recorded in the seismograph of each station is expressed as an index considering the depth of the epicenter and the distance to the epicenter. In addition, the magnitude of the earthquake is a numerical expression of the intensity of vibration that appeared in a place, the feeling of a person, or the degree of shaking of an object or structure around it. The magnitude depends greatly on the magnitude of the earthquake and the depth of the epicenter, and the seismic wave types and properties are classified into surface waves and real waves. Real waves are classified into longitudinal (P) waves and transverse (S) waves, which may differ in shape depending on the geological structure of the region and the shape and population status of the structure. Thus, magnitude and magnitude are not necessarily one-to-one correspondence, and the magnitude of magnitude may be the same in several regions for a single earthquake, but the magnitude of magnitude may vary. That is, the magnitude of the earthquake is the same, but the magnitude decreases as the distance increases.

Progressive classes are not globally united and countries use measures that are appropriate to their situation. Korea has used the Modified Mercalli Intensity scale since 2001. The details of each progress class are as follows.

Progression What happens I Fine vibrations. Feeling very few in special conditions II Very few feeling indoors III Feeling prime in the room. The hanging object moves weakly IV Numerous feelings indoors. Not detectable outdoors V The whole building shakes. Breakage, overturning, falling, moving of light objects VI Difficulty walking straight. The walls of weak buildings fall or crack. Move or flip the position of a heavy object VII Difficult to stand. Feel the earthquake while driving. Walls collapse, loose loads and fences collapse VIII Difficult to drive a vehicle. Some buildings collapsed. Slopes or surface cracks. Tower, chimney collapse IX Heavy building damage or collapse. Surface cracks and underground pipe rupture X Destroy the majority of solid buildings and structures. Cracks in the ground. Massive situation. Asphalt cracks

However, such natural disasters such as earthquakes have not been provided in Korea yet.

The present invention prevents secondary disasters such as fires and explosions by appropriately blocking and controlling the supply of combustible materials such as gas and oil and power and power supplied into a building and distributed to a plurality of mechanical devices in an emergency such as an earthquake. It is an object to provide a device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The earthquake disaster prevention master controller unit including the earthquake detection sensor according to the present invention is a mechanical equipment automatic control system for controlling various machinery installed in the machine room of the building and each part of the building, the power for controlling the power in the building It is a unit additionally installed as part of an automatic building control system including an automatic control system, an automatic lighting control system, an entrance control and an entrance control automatic control system for verifying the identity of an individual. Referring to FIG. 1, a DDC panel of a mechanical control system is operated by a central control unit for controlling the operation of machinery in a building, and the DDC panel of the mechanical control system is controlled. Various valve blockers and various mechanical control panel (MCC) panel has a structure that can simultaneously control the earthquake disaster prevention master controller unit according to the present invention. On the other hand, the earthquake disaster prevention master controller unit may operate in conjunction with the mechanical control system D.D.C panel, but may directly control various valve shutoff devices and various mechanical M.C.C panels while directly interlocking with the automatic building control system.

2 shows a schematic view of a building to which the earthquake disaster prevention master controller unit is applied. According to this figure, various mechanical devices are installed in the machine room formed at the lower part of the building. The machine room also houses high-voltage power lines (not shown) and pipelines (not shown) that are supplied with combustible materials such as gas or oil, and supplies power through the MCC panel 310 to the building. At the same time, various machinery such as general boilers, special boilers, hot and cold water heaters, heat tanks, pumps, and air conditioners are installed to drive gas or oil from pipelines.

As described above, the master controller unit 200 for earthquake disaster prevention according to the present invention installed in a building may measure the intensity of vibration detected by the earthquake detection sensor 100 buried in the bottom or the ground of a building based on a predetermined reference, for example. Measure the current progress class (current progress class) based on the modified Mercali progress class, and output an appropriate earthquake alarm as a visible audible signal to inform that an earthquake has occurred based on this current progress class, and at the same time, the MCC Among power supplies branched from the panel 310, the power supply to a mechanical device having a high risk of an accident due to electric shock or electric leakage is selectively cut off, and a fire or explosion among the mechanical devices to which flammable substances such as gas or oil are supplied. When driving the electric valve 410 installed in the gas oil supply pipeline supplied to the machinery of high risk of accidents By the flow control or cut off it makes it possible to prevent secondary disasters due to the earthquake.

3 shows the structure of the earthquake disaster prevention master controller unit 200 performing such an operation. The earthquake-disaster prevention master controller unit according to this drawing comprises an earthquake detection sensor 100, magnitude class converter 220, memory 230, alarm generator 240, communication unit 260, power supply 250 And, may further include an alarm indicator 270, the power breaker 300, the valve shut-off driver 400.

In addition, Figure 4 is a view showing the configuration of the earthquake disaster prevention master controller unit 200, a view for explaining the external connection terminals in detail.

The earthquake detection sensor 100 is generally buried in the bottom of the building or the ground near the building to detect the vibration caused by the earthquake, and outputs the electrical signal, generally analog signal.

The magnitude class converter 220 receives a signal detected by the earthquake detection sensor 100 and outputs the converted signal to a predetermined value (current magnitude class) based on the modified mercali magnitude.

The memory 230 stores earthquake alarm signals that should be output for each magnitude of progress. The earthquake alarm signal includes a power cutoff signal and a valve cutoff signal. The power cutoff signal is a signal for controlling the power cutoff device 300 installed in the MCC panel 310 to selectively cut off the power supplied to the mechanical device, and the valve cutoff signal is the flammability of the gas and oil supplied to the mechanical devices. It is a signal for controlling the valve blocking driver 400 for controlling the flow rate by driving the electric valve 410 installed in the pipeline for supplying the material. The setting and output of such an alarm signal can be easily understood with reference to Table 1 below.

In addition, the alarm generator 240 generates a predetermined earthquake alarm signal corresponding to the current magnitude of magnitude output by the magnitude class converter 220 by reading from the memory 230, and generates the earthquake alarm signal to the communicator 260. Output through This earthquake alarm signal generally outputs a power cutoff signal for preventing a disaster and a valve cutoff signal for shutting off the supply of combustible materials such as gas or oil when the magnitude of the magnitude is greater than '6'.

The progress class outputting such a power cutoff signal and a valve cutoff signal may generally be set to '6', but may be changed to a lower progress class or a higher progress class as necessary. Of course, the earthquake alarm signal output from the alarm generator 240 is set individually for each progress class from the progress class '1' to '10' or more.

The communicator 260 includes a digital input terminal 261, a digital output terminal 262, a telephone terminal 263, and an RS232C communication port 264. The digital input terminal 261 is a port for receiving information indicative of operating states of various machines connected to the master controller unit 200 and confirming the status of how these machines are currently operating. The digital output terminal 262 is a port for outputting a signal (for example, an earthquake alarm signal) generated by the master controller unit 200 to be controlled by various connected mechanical devices. In this case, the mechanical device connected to the digital input terminal 261 and the mechanical device connected to the digital output terminal 262 are preferably the same mechanical device, whereby the current operation of the mechanical device and the master controller unit 200 are performed. Feedback control with the signal output from is possible. The telephone terminal 263 may be connected to a mobile communication network, a wired telephone network, or an internet network. The telephone terminal 263 transmits an earthquake alarm signal generated by the master controller unit 200 through a predetermined mobile phone, wired telephone, or the Internet. It can be delivered to the terminal. The RS232C communication port 264 is a port for transmitting all signals transmitted and received by the master controller unit 200 and all information including the generated progress class to a connected computer. The RS232C communication port 264 can transmit and maintain the sensed vibration intensity, seismic date and time, seismic waveform, calculated current magnitude, etc. to the computer. It is also possible to maintain the operation status, control results and the like.

The power supply 250 supplies driving power of the master controller unit 200 for earthquake disaster prevention. The power supply 250 is preferably configured as an uninterruptible power supply (UPS) in order to ensure normal operation even in the case of power failure due to an earthquake.

Meanwhile, referring to FIG. 6, an alarm indicator 280, a power circuit breaker 300, and a valve blocking driver 400 may be further connected to the earthquake disaster prevention master controller unit 200.

The alarm indicator 280 may include a warning light or a speaker of a broadcasting system in a building, and may be installed in parallel with a remote location or a central disaster prevention center.

The power breaker 300 selectively cuts off power supplied from the MCC panel 310 to various mechanical devices in the building by relaying and controlling a plurality of power supply contacts or power supply wirings formed on the MCC panel 310. . That is, the power breaker 300 indicates a power supply wiring distributed from the MCC panel 310 and connected to various mechanical devices based on a power cut signal output from the master controller unit 200. It comprises a plurality of switches to turn on / off the power line to the machine.

The valve blocking driver 400 controls the opening and closing or flow rate of the electric valve 410 provided in the pipeline indicated by the valve blocking signal based on the valve blocking signal output from the master controller unit 200.

In the present invention, the power cutoff signal provided from the master controller unit 200 to the power breaker 300 in the event of an earthquake is mainly for mechanical equipment using a high-voltage power supply, pumps for fire extinguishing in buildings, It is preferable to maintain a power supply for a fire suppression machine such as a ventilation fan, and the master controller unit 200 also provides a signal instructing the operation of an emergency power supply or the like which should be operated in an emergency such as an earthquake. You can also print it separately. Of course, in this case, the power supplied to the emergency power supply or the power supplied from the emergency power supply may be set so as not to be cut off by the power cutoff signal that is generated later.

In other words, among machinery facilities, machinery using high voltage power, machinery using combustible materials such as city gas, LPG and diesel, and boilers producing high pressure steam or hot water are fired due to short-circuit leakage or pipeline rupture. Or because of the high risk of explosion, such devices as, for example, high pressure steam boilers, hot water boilers, heat tanks, chemical tanks, cooling towers, pumps, air conditioners, water tanks, ventilation In the case of fans, the valve shut-off driver 400 and the electric valve 410 installed in the pipeline for supplying combustible materials such as gas and oil supplied from the machine room are first blocked by the valve shut-off signal, and the pressure may be high and explode. The high boilers first cut off the power to the power circuit breaker 300 by the power interruption signal. In addition, other devices are to be properly disconnected according to the magnitude of the earthquake. In addition, the order of interruption of the power circuit breaker 300 and the valve blocking driver 400 may be individually set, and the pipeline of the combustible material such as gas, oil and the like may be blocked according to the progress level.

In this case, various formats of signals may be used as the power cutoff signal and the valve cutoff signal, and the present invention is not particularly limited. Therefore, this can be variously modified by those skilled in the art to which the present invention pertains.

[Table 1] below shows the control of the power class breaker and valve drive breaker according to the progress level, and the alarm by the alarm indicator.

Progression Earthquake Notification Setting Power off setting Electric valve shutoff setting Alarm content I Save to control system II Save to control system III Save to control system IV Save to control system "An earthquake of magnitude 4 has occurred" (single broadcast and voice notification) V Save to control system, voice notification to administrator "An earthquake of magnitude 5 has occurred" (1 ~ 2 broadcasts and voice notification) VI Save to control system, alert voice to administrator, alarm in building Gas boilers, part of circulation pump gas "An earthquake of magnitude 6 has occurred" (2-3 times broadcast and voice notification) VII Stored in the control system, voice notification of evacuation to the administrator, broadcast of evacuation in the building Circulating pumps, oil boilers, steam boilers, air conditioners, cooling towers Oil, flammable, steam, chemical tank, heat tank "An earthquake of magnitude 7, please evacuate out of the building orderly" (5 times and voice notification) VIII Stored in the control system, emergency evacuation voice notification to the administrator, emergency evacuation broadcasting in the building Air Conditioners, High Pressure Steam Boilers All equipment except water tank "An earthquake of magnitude 8, please evacuate out of the building in an orderly manner" (more than 5 times broadcast and voice notification) IX Stored in the control system, emergency evacuation voice notification to the administrator, emergency evacuation broadcasting in the building Water tanks, drainage pumps, ventilation fans, hydrant pumps Water tank "An earthquake of magnitude 9, please evacuate out of the building in an orderly manner" (more than 5 times broadcast and voice notification) X Stored in the control system, emergency evacuation voice notification to the administrator, emergency evacuation broadcasting in the building "An earthquake of magnitude 10, please evacuate out of the building in an orderly manner."

Hereinafter, with reference to Figure 6, the operation flow of the earthquake disaster prevention master controller unit according to the present invention. First, the earthquake disaster prevention master controller unit monitors the signal output from the earthquake detection sensor to determine whether an earthquake has occurred. At this time, when the earthquake detection sensor 100 detects an earthquake occurrence and outputs a predetermined signal (S10), the signal is a magnitude class based on the criteria of the mercali progress class for indicating the strength of the earthquake that is generally used. Progress class) is converted (S20).

Then, according to the converted progress class outputs an alarm signal for each progress class that is set and stored in advance (S30). That is, when the progress class is low, if the progress class is '1' or more and '3' or less, the alarm of earthquake is not generated.If the magnitude is less than '4' or '5', In addition to earthquake alarms, earthquake alarms should be output to management offices, remote terminals, and alarm broadcasts. Up to this point, no power cutoff signal or valve cutoff drive signal is generated.

Afterwards, if the magnitude of the magnitude is '6' or more, in addition to the earthquake alarms in the above magnitude, the earthquake alarms may be output in a predetermined order for the machinery inside and outside the building.

On the other hand, when the progress class is a dangerous progress class by exceeding the '7' will output a more enhanced alarm and power cutoff signal, the valve cut-off drive signal to prevent the disaster caused by the power in the building (S40). That is, the sound can be output to the enhanced warning and evacuation to a safe location than to inform that the progress class has exceeded the dangerous progress class, the mechanical device of high risk of accidents in the building from the MCC panel 310 Selectively shuts off the electric valve 410 installed in the pipeline to mechanical devices with a high risk of fire due to combustible materials such as gas or oil supplied to the controller by outputting a valve blocking signal from the master controller unit 200. Done. At this time, the evacuation broadcast may be output at the same time to induce people to evacuate to a safe place from inside the building. In addition, it may further output a signal for controlling the emergency power source for driving the emergency exit induction lamp and the pump for fire extinguishing, and if necessary, further output a signal for operating the emergency power supply for emergency operation of each machine. For example, a building can be switched to an emergency power supply.

Afterwards, when the progress class is lowered to a safer level lower than the dangerous progress class, the seismic alarm is modified to match the current progress class and the earthquake is continuously monitored. At this time, the power supply is not automatically restored to the mechanical device is cut off, by the administrator of the power supply device to restore the power supply manually (S50), the earthquake disaster prevention mechanical control device according to the present invention Minimize the risk of malfunctions that may occur.

According to the earthquake disaster prevention master controller unit of the present invention by the above configuration and method, the earthquake leakage caused by the earthquake and the leakage of flammable materials such as gas or oil in devices using high voltage power and flammable materials such as gas or oil installed in buildings The possibility of a fire or an explosion can be minimized by cutting off the power supplied to these devices from the MCC panel, and cutting off combustible materials such as gas or oil from the electric valve. Therefore, it is possible to obtain an excellent effect of reducing the fire caused by earth leakage and flammable substances, such as gas or oil, and the loss of human life and property loss caused by the earthquake.
