1 is an overall configuration diagram of a water distribution facility employing an abnormal state determination-control system according to the present invention.

Referring to FIG. 1, the power distribution facility 100 is configured with a device for determining a state as a normal state or an abnormal state based on signals sensed for each component provided in the water distribution facility 100. The water distribution facility 100 determines whether the detected signal is in an abnormal state and the effect of one detection signal on the other detection signal, and stops the entire operation according to the determination result.

In order to achieve this operation, the water distribution facility 100 has multi-sensors composed of at least two or more, and data changes of signals detected by these sensing means are dataized.

The sensing means includes a temperature sensing sensor that senses temperature, a vibration sensing sensor that senses vibration, a smoke sensing sensor that detects smoke, a photographing unit that shoots smoke, and a humidity sensing sensor that senses humidity. Since temperature or humidity is not visually confirmed, it does not belong to the subject, and if the vibration is relatively large, capturing the image will help to determine the condition of the water distribution system, but micro-vibration may occur under normal operation. Most of them are also excluded from shooting. On the other hand, smoke is mostly confirmed visually, so it is included in the subject. If the smoke is photographed, a cause for generating smoke, for example, a flame, etc., may also be photographed, and this may also be used to determine the state of the water distribution facility.

The terminal 200 is a manager terminal, and is a smartphone, PC, laptop, etc. capable of wired / wireless communication over the Internet, and is not limited in its type. The terminal 200 is operated to receive status information transmitted from the water distribution facility 100 and take appropriate measures. The terminal 200 may be a device belonging to the control center 300, which will be described later, or may be a terminal configured to be one-to-one with the water distribution facility 100 to manage only one specified water distribution facility. In this case, since only a specific terminal is connected to a specific water distribution facility, for example, a unique ID as a means for distinguishing it from other water distribution facilities does not need to be separately provided. On the other hand, a terminal belonging to the control center 300 is a terminal carried by an administrator belonging to the control center 300, and this manager can be regarded as a person who manages one or more water distribution facilities. Therefore, in this case, a unique ID should be assigned to each power distribution facility and managed.

The control center 300 includes a server that manages a plurality of water distribution facilities 100. The control center 300 may assign a unique ID for each water distribution facility to manage the plurality of water distribution facilities 100. These IDs are shared when the terminal 200 is a terminal belonging to a control center.

In the system of the present invention configured as described above, status information from the water distribution facility 100 is simultaneously transmitted to the terminal 200 and the control center 300. In addition, the terminal 200 and the control center 300 transmits the status information transmitted from the water distribution facility 100 to the water distribution facility 100 in reply.

Although the power distribution and distribution facility 100 has transmitted status information to the terminal 200 and the control center 300, respectively, both the terminal 200 and the control center 300, or the terminal 200 or the control center 300 ) If no reply is received from any one, the water distribution facility 100 recognizes this and transmits status information back to the terminal 100 and the control center 300. If no reply is received from either the terminal 200 or the control center 300, the terminal 200 or the control center 300 that normally receives status information does not normally receive the status information 200 ) Or the water distribution facility 100 controls the terminal 200 or the control center 300 to transmit to the control center 300.

Referring to FIG. 2, the abnormal state determination and control system of a water distribution facility according to an embodiment of the present invention includes a temperature sensor 110, a vibration sensor 120, a smoke sensor 130, and a photographing unit 140 ), A humidity sensor 150 and a control unit 160.

The temperature sensor 110 detects the internal temperature of the water distribution facility 100 and provides the detected temperature data to the controller 160. Here, the internal temperature of the power distribution and distribution facility 100 may be entirely sensed by a single sensor, or a sensor may be provided for each zone in which each component is located to sense the temperature for each zone.

The steady state or abnormal state of the temperature sensed by the temperature sensor 110 may be determined by being separated only by the temperature generated in each zone, and the smoke having a predetermined temperature is combined with the temperature of the smoke as it passes through the zone. It can also be judged by the elevated temperature. It can also be judged by the temperature that is higher than the original temperature due to the influence of the temperature generated in other zones.

The vibration detection sensor 120 detects vibration of the water distribution facility 100 and provides the detected vibration data to the control unit 160. Here, the vibration may be vibration according to a normal or abnormal operation of the water distribution facility 100 or vibration in a state where the operation is stopped. In the case of vibration in a state in which the motion is stopped, for example, physical force applied from the outside, thunder or earthquake may be mentioned. The vibration detection detects the entire vibration of the water distribution facility 100 as one.

The smoke detection sensor 130 detects smoke generated inside and outside of the water distribution facility 100 and provides the detected smoke data to the control unit 160. Here, the acting may be acting according to the operation of the water distribution facility 100 or acting irrespective of the acting. When smoke is generated regardless of operation, it may be, for example, smoke generated from the outside and flowing into a water distribution facility.

The photographing unit 140 photographs the smoke and provides the photographed smoke data to the control unit 160. In the case of a water distribution facility, since most of the light is blocked by the housing and operated, there may be no light inside the water distribution facility.

Accordingly, in one embodiment, when it is checked that smoke is detected by the smoke detection sensor 130, it is activated to turn on a flash (not shown) to brighten the surroundings and then take a smoke image.

In another embodiment, the imaging unit 140 may use an infrared camera capable of photographing a range put in a dark place without requiring additional lighting.

In addition to being detected by the smoke detection sensor 130, the smoke is separately photographed to be used as information for determining the normal or abnormal state of the water distribution facility 100.

The image captured by the photographing unit 140 is a video, and not only photographs the movement path of the smoke, but also determines the effect of the smoke on the area where the smoke mainly stays when the movement speed of the smoke and the movement speed of the smoke are slow. .

As illustrated in FIG. 4 to be described later, the photographing unit 140 photographs a moving path of smoke as a video, and determines whether to stop the operation of the water distribution facility by classifying and processing the influence on each area due to the movement of smoke. Decide.

The humidity sensor 150 is disposed on each component to detect the humidity of each component and provides the detected humidity measurement value to the controller 160. Humidity in adjacent areas where each component is located inside a water distribution system operating under normal conditions may be similar. However, in the case of a water distribution facility operated in an abnormal state, the humidity may drop rapidly when smoke or fire occurs in a specific component. In this embodiment, it is used as data for determining the normal or abnormal state of each component based on the humidity difference value rapidly decreasing with time or the humidity difference value rapidly decreasing with area.

The control unit 160 includes an abnormal state determination unit for determining the state of the water distribution facility 100, and generates a control signal such as an operation stop according to the determination result by the abnormal state determination unit. The operation stoppage can be divided into stopping the entire operation of the water distribution facility and stopping the operation of some components of the water distribution facility. When the operation of some components is stopped, if the original function of the water distribution facility cannot be achieved, this is the same as the operation of the entire operation is stopped. It would be good to have a limited application only for the operation. A fan may be mentioned as an example of this.

In addition, the abnormal state determination-control system of the water distribution facility according to an embodiment of the present invention may further include a signal generator 180 and a communication unit 185 connected to the signal generator 180. Here, the signal generation unit 180 generates a signal for the status information of the water distribution facility determined by the control unit 160. The communication unit 185 receives the signal for the status information of the water distribution facility determined by the control unit 160 through the signal generation unit 180 and transmits the signal to the terminal 200 or the control center 300 disposed at a remote location. do.

Additionally, the abnormal condition determination-control system of a water distribution facility according to an embodiment of the present invention includes a display unit for displaying the movement path of smoke, the temperature of each component, etc., along with the arrangement of various components provided in the water distribution facility ( 190) may be further included. The user can visually check the operating state of the components provided in the water distribution facility through information such as the movement path, temperature, and humidity of the smoke displayed on the display unit 190.

If value) is checked to the maximum, the corresponding area can be determined as the ignition location.

Further, the control unit 160 may determine that the temperature rise of the corresponding zone is a temporary increase when the passage speed through which the smoke passes through the corresponding zone is faster than the reference speed through the provided abnormal state determination unit 600.

In addition, if the residence time of the smoke does not last through the provided abnormal state determination unit 600 and the temperature of the corresponding zone continues to rise, the control unit 160 increases the temperature of the corresponding zone when it is checked that the humidity drop is greater than the reference value.

For example, if the humidity measured at the first time was 40% and the humidity measured at the second time was 35%, the humidity difference value could be extracted as 5, and the humidity measured at the first time was 40% and the second If the humidity measured in time was 20%, the difference in humidity can be extracted as 20.

Subsequently, difference information of humidity is mapped to the map (step S290). In this embodiment, the map is a representation of components arranged inside the water distribution facility in the form of a map. The map to which the difference information of humidity is mapped may be displayed on the display unit 190 shown in FIG. 2 according to the user's manipulation.

Meanwhile, step S220 of mapping difference information of humidity to a map or step S290 of mapping a movement path of smoke to a map may be omitted.

If it is checked in step S310 that the temperature of the specific zone is abnormal, it is checked whether the humidity drop is the maximum compared to other zones (step S312). The check may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S312 that the humidity drop is the maximum compared to the other zones, the zone is determined to be the ignition location (step S314), and then feedback to step S400. The above determination may be performed by the control unit 160 shown in FIG. 2.

If it is not checked in step S312 that the humidity drop is the maximum compared to other zones, it is checked whether smoke passes through the zone (step S316). The check may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S316 that the smoke passes through the zone, the passage speed is analyzed (step S318). The above analysis may be performed by the control unit 160 illustrated in FIG. 2.

After analyzing the passing speed, it is checked whether the passing speed is greater than or equal to a predetermined speed value (step S320). The check may be performed by the control unit 160 shown in FIG. 2.

If the passing speed is checked at a predetermined speed or higher in step S320, the temperature rise of the corresponding zone is judged to be a temporary rise (step S322), and then feedback to step S400. The above determination may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S320 that the passing speed is not equal to or greater than a predetermined speed value, it is checked whether or not the residence time of the smoke continues (step S324). The check may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S324 that the residence time of the smoke has not persisted, it is checked whether or not the temperature of the corresponding zone continues to rise (step S326). The check may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S326 that the temperature of the corresponding zone continues to rise, it is checked whether the humidity drop is greater than the reference value (step S328). The check may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S328 that the humidity drop is greater than the reference value, it is determined that the component itself is abnormal (step S330), and then feedback to step S400. The above determination may be performed by the control unit 160 shown in FIG. 2.

If it is checked in step S326 that the temperature of the corresponding zone has not continuously increased or in step S328 that the humidity drop is not greater than the reference value, the temperature rise of the zone is judged to be a temporary rise (step S332), and then feedback to step S400 do. The above determination may be performed by the control unit 160 shown in FIG. 2.

On the other hand, if it is checked in step S324 that the residence time of the smoke is continued, the temperature rise of the corresponding zone is judged to be an increase due to the influence of the smoke (step S334), and then feedback to step S400. The above determination may be performed by the control unit 160 shown in FIG. 2.

As described above, according to the present invention, it is possible to control the operation of the water distribution system under more accurate judgment by determining all the various factors without considering the abnormal state of the water distribution facility only in one element. have.

In particular, it is possible to determine the effect of the change in the movement path and humidity of the generated smoke on each component and stop the entire operation of the water distribution facility or stop the operation of some components of the water distribution facility based on this. In addition, when determining the area where the component with the greatest drop in humidity is located as the ignition location, it is possible to determine which component is the cause of the ignition, thereby enhancing the fire prevention effect when designing or arranging the component.

In addition, by determining the abnormal state of the water distribution system by reflecting not only internal factors but also external factors, it is possible to escape from relying only on the detection signal by the detection means configured inside the conventional water distribution system, and apply a wider range of factors. Its operation control is possible.
