Description

[PROBLEMS] To provide a leak prediction and alarm system and a method of operating the fire water system using the LPWA wireless communication module,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leakage prediction and alarm system and a method of operating the same in a water-

More specifically, since the installation is simple and the signal transmission is not disturbed by the building, it is easy to apply to a large-scale water-based facility constructed in an already-constructed and aged building and a new high- And more particularly, to a leak prediction and alarm system for a water treatment facility using a new type of LPWA wireless communication module.

Generally, buildings are equipped with fire extinguishers such as fire extinguishers, fire hydrants, and sprinklers in the building for early suppression when a fire occurs. Sprinklers and fire hydrants are a typical water system, connected to fire-fighting pipelines, installed on the ceiling inside the building, receive fire-fighting water from fire-fighting pipelines, fire fire water downward when a fire occurs, .

If leakage occurs at a specific location in the piping network of a water-based fire-fighting system, the water pressure is lowered and the fire suppression can not be performed normally. Such leaking phenomenon can cause inconvenience in life especially in an aged apartment.

However, it is difficult to confirm the occurrence of leaking phenomenon and it is difficult to clearly identify the leaking point because the fire-extinguishing system piping network has a long total length and is installed in a complex structure on the inner wall or ceiling of the building.

In other words, it is necessary to be able to clearly monitor the current leakage situation, and it is possible to perform effective fire-fighting work in case of fire, and the construction work for solving the leakage phenomenon can be effectively performed by accurately grasping the leakage point.

In recent years, not only large apartment complexes, but also high-rise apartment complexes are being built with high-rise buildings. In the situation where the conventional small - scale / single - storey apartment complexes have been widely deployed, the structure and size of the fire - fighting water system are relatively simple and small, but recent buildings are becoming high - floor units.

That is, in recent high-rise building fires, the problem is that equipment for fire suppression such as fire trucks and ladder cars operated by the front line fire department has little utility in the field of high-rise building fire, There is a growing demand for inspection.

Therefore, it is easy to install and signal transmission is not disturbed by the building, so leakage monitoring of a new type of fire-fighting water system facility, which is easy to apply to a large-scale water system equipment constructed in an old- System is required.

In addition, there is a need to develop an alarm system capable of predicting and alerting a leakage phenomenon by using such a leakage monitoring system.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the detailed description of known functions and configurations incorporated herein will be omitted when it may unnecessarily obscure the subject matter of the present invention.

The same reference numerals are used for portions having similar functions and functions throughout the drawings. Throughout the specification, when a part is connected to another part, it includes not only a case where it is directly connected but also a case where the other part is indirectly connected with another part in between. In addition, the inclusion of an element does not exclude other elements, but may include other elements, unless specifically stated otherwise.

Hereinafter, the configuration and function of the leakage prediction and alarm system of the water-purifying water system using the LPWA wireless communication module according to an embodiment of the present invention will be described.

FIG. 1 is a diagram illustrating an example of a UI applied to a leak prediction and alarm system of a water-purifying water system using a LPWA wireless communication module according to an embodiment of the present invention.

Referring to FIG. 1, members such as a linear pipe, a T-joint, a cross, an elbow-type connection pipe, a nozzle and a pump for controlling the required flow rate and pressure form pipes for delivering the water for fire fighting, It can be expressed as an intuitive symbol that is easy to grasp the shape or function of the members.

For example, the diameter of a pipe is an important pressure-forming element that directly affects the water pressure inside the pipe. Therefore, even if a straight pipe is used, the pressure distribution of the entire pipe can be grasped quickly by using a straight line symbol which differs depending on the diameter.

On the piping, a node number, a pipe number, and a length are displayed.

The node number can contain functions and meanings such as the "address" of the entire piping structure. The UI example shown in FIG. 1 is a user interface that shows an actually installed pipeline in an intuitive shape. However, since it is different from the actual design drawing, real-time information such as pipe length and pipe number, Can be helpful in understanding.

A node can be set at all kinds of members constituting a pipe or at a connecting portion between a member and a member, and a long pipe can set a node at a plurality of positions on a pipe, The convenience can be improved.

The GUI shown in Fig. 1, which can easily grasp the relative water pressure distribution of the piping network of the entire water system, even if the quantitative data is not displayed, allows the manager to quickly make judgments and cope with an emergency situation, In addition to minimizing damage, it also enables quick and appropriate response when a water system malfunction occurs.

1 is a graphical user interface (GUI) diagram applied to a water leakage prediction and alarm system of a water system for fire fighting using an LPWA wireless communication module according to an embodiment of the present invention. , It is easy to quantitatively compare the pressure measured intuitively with the actually measured pressure measurement value in the UI. That is, by comparing the pressure measurement value difference of any two nodes set at different positions in the UI which is a symbol of the main factors for determining the pressure, it is possible to quickly ascertain whether the pressure measurement value is abnormal have.

Also, the pressure in the piping can be mathematically calculated. The factors that determine the water pressure in the pipe may be the structural features of the pipe and the structure and function of the connecting pipe and other members.

The diameter of the pipe, its length, and the roughness of the head and inner surface of the pipe can all be factors that influence the internal pressure determination.

In addition, the T, cross and elbow type connecting pipes can provide a factor that hinders the flow of the water flowing through the pipe due to the specificity of the shape. Thus, the water pressure at the point of entry into these connecting pipes can be high, and the water pressure at the point of entry from these connecting pipes can be relatively low. Both the nozzle and the pump can change the flow rate, which can be a factor that can affect the water pressure.

Accordingly, when the structural characteristics of the piping member and the mathematical expression for calculating the pressure in the piping are synchronized in the GUI shown in FIG. 1, the pressure estimation value changed according to the GUI change is calculated, can do.

When the pressure is calculated in the piping, the operation of the nozzle and the pump installed on the piping can be controlled to supply the flow rate of the fire water to be needed when a fire occurs.

In one embodiment of the present invention shown in Fig. 1, U.I. In order to arrange the pressure information of the actual fire-fighting water in the example together, a node should be set on the pipe and a pressure sensor should be installed on the set node to measure the pressure inside the pipe.

As described above, as recent buildings have become larger and larger, the overall length of the fire-fighting water system becomes longer and the structure becomes more complicated. In the event of a fire, a fire-extinguishing facility supported by the outdoors, namely, a fire truck with an elevated ladder or a refraction ladder The building is being built up so that it can not rely on fire fighting work only for airborne disaster prevention equipment which used helicopter.

Therefore, since the number of nodes set in a single water treatment facility can be in the range of tens to hundreds or more, the pressure measured from a pressure sensor installed at a node proportional to the size and complexity of the piping facility The degree of difficulty of establishing a communication network for receiving the service can be increased.

The node shown in FIG. 1 is the same as the address of the pipe network, and one pressure sensor unit is installed at one node to generate a pressure measurement value as a measurement value of the fire water pressure inside the pipe at the corresponding point and transmit the pressure measurement value to the upper system. In order to receive the information including the pressure value measured from the pressure sensor unit, a communication network with the pressure sensor unit must be established. This communication network is a device for monitoring water-based fire-fighting equipment. Even if it occurs, the whole network should operate normally.

The wireless communication network can be applied to meet the requirement of the communication network connecting the pressure sensor unit installed in the pipe network of the fire water system. Especially, the Internet of Things (IoT) Pressure sensor unit installed in a complicated and large-scale fire-fighting water supply system by using a low power wide-area wireless communication (LPWA) that complements the disadvantages of Bluetooth and WiFi technology. Can be maximized.

Fig. 2 compares the characteristics of mobile communication networks including LPWAN, 3G and 4G communication networks.

Referring to FIG. 2, the LPWAN (Low Power Wide Area Network) applied to the leakage prediction and alarm system of the water system for fire fighting according to the present invention meets the main requirements required by the communication network for various emergency situations .

That is, not only the obstacle transmission performance is excellent but also the transmission distance is short, stable coverage can be provided even in a large-sized complex having a complicated structure. In addition, it is possible to design a low power consumption. Considering that there are few technologies that can sustain long-lasting service among the battery-based IoT devices that are currently being commercialized, have.

On the other hand, the cost of the wireless chipset and service costs are very low, and the number of stations such as wireless access points (APs) is significantly lower than conventional wireless communication technologies such as 3G or 4G. It has a low bandwidth and is suitable for a small capacity network.

As described above, there has been an increase in the number of high-rise buildings and large-sized buildings, and various facilities such as various communication facilities, gas, electric facilities, and water and sewage facilities have been installed complicatedly. It is very difficult to provide a wired line in establishing a communication network of a pressure sensor unit for measuring water pressure in a fireplace in various complex facilities networks. If a fire occurs and a short circuit occurs in a certain section, There is also a problem that the whole network is paralyzed.

LPWA is simple to install and maintain. Since a wireless communication line is used, it is not necessary to provide a complicated wired line. As a low-power device, it can be operated for several years with one installation. Particularly, since the amount of data to be measured and transmitted in the pressure sensor unit is not large, the slow speed is not a big problem.

The biggest problem of the wireless communication line is obstacle transmission. Conventional Bluetooth can communicate smoothly within a few meters even in open areas. In addition, although the wireless communication method using the Wifi technology can transmit a distance of about 50m in an open space, it is practically possible to communicate within 10 to 20m due to obstacles such as building walls and furniture in a building.

Since LPWA has excellent obstacle permeability, excellent transmission characteristics can be expected even if it is installed on the inner wall of a complex building.

The most recently set up LPWA goal is to reach a communication range of 5 to 40 kilometers and battery life is known to be more than 10 years.

FIG. 3 is a block diagram of a leak prediction and alarm system of a water-purifying water system using the LPWA wireless communication module according to an embodiment of the present invention.

Referring to FIG. 3, the leakage prediction and alarm system of the water purifier system using the LPWA wireless communication module according to an embodiment of the present invention includes a water purifier system 100, a receiving facility 200, and a monitoring device 300 Can be obtained.

The fire fighting water system 100 includes piping 110 to which the fire water is transferred, a pressure sensor unit 120 to measure the pressure of the fire water in the pipe 110, and pipe measurement information 121 for communicating with the mobile communication terminal.

The pressure sensor unit 120 measures the water pressure of the fire water in the pipe 110, and the measured pressure measurement value 121-2 is transmitted through the communication module. At this time, the pressure sensor unit 120 detects the specific position 121-1 at which the pressure sensor unit 120 is installed and the specific time 121-3 at which the pressure measurement value 121 is measured in addition to the pressure measurement value 121-2. Can be generated at the same time.

The specific location 121-1 may be the same as the node described in Fig. Therefore, the specific position 121-1 is positional information based on the structure and shape of the entire piping 110, and specifies the specific position 121-1 in the pipe structure information 11 input by the manager 10 can do.

The specific time 121-3 includes time information for measuring the pressure measurement value 121-2 by the pressure sensor unit 12 and measures the pressure measurement value 121-2 by the pressure sensor unit 12 May be repeated with a predetermined period of time.

The pressure measurement value 121-2, the specific position 121-1 and the specific time 121-3 can be bundled with the piping measurement information 121. Based on the specific time 121-3, Lt; RTI ID = 0.0 > 130 < / RTI >

The communication module 130 is installed adjacent to the pressure sensor unit 120 to be distant from the receiving facility 200 at a long distance since the communication module 130 uses a low power wide area (LPWA) Communication is possible even if the building wall or other obstacles are distributed.

The receiving facility 200 may transmit the light distribution measurement information 121 received from the communication module 130 to the U.I. processing unit 310 and the storage unit 340 and the determination unit 350 of the monitoring apparatus 300. [

The monitoring apparatus 300 may include an input unit 330, a U.I. processing unit 310, a U.I. display unit 320, a storage unit 340, a determination unit 350, and an alarm unit 360.

The input unit receives the piping structure information 11 and the safe operation range 12 from the manager 10 and can transmit the pipeline structure information 11 and the safe operation range 12 to the U.I processing unit and the arithmetic unit 400.

The UI processing unit calculates the pressure measurement values 121-1 and 121-2 based on the position 121-1 information of the pipe structure information 11 received from the input unit 330 and the pipe measurement information 121 received from the reception facility 200. [ 2) to the piping structure information 11 to generate UI (User Interface) information 311. FIG.

That is, the UI information 311 is information in which the position of the pressure sensor unit 120 is mapped to the structure of the piping 110, and information indicating the position at which the pressure sensor unit 120 is installed in the piping 110 to be.

The U.I. display unit displays the U.I. information 311 using a previously stored U.I program. The U.I program is a program for converting the piping structure information 11 and the piping measurement information 121 included in the U.I. information 311 into U.I such as the UI example shown in FIG.

A GUI (Graphic User Interface) type using a graphic can generally be applied to a U.I. program, and a three-dimensional GUI can be used according to the complexity of the piping 110. Or a two-dimensional table type in which the pressure measurement value 121-2 is arranged on the basis of the specific position 121-1 and the specific time 121-3 may be applied depending on the structure of the pipe 110. [

The storage unit 340 stores the UI information 311 in a time series on the basis of the specific time 121-3 information included in the pipe measurement information 121, And can be used as data and is listed in a time series, so that by observing the pressure change over time, an abnormal pressure measurement value can be detected.

The manager 10 can input the piping structure information 11 and the safe operation range 12 information to the monitoring apparatus 300 through the input unit 330. [

The piping structure information 11 includes information on the structure of the piping 110, and preferably includes a pipe shown in FIG. 1 and a connection pipe of a T-shape, a cross, an elbow, a nozzle for controlling the required flow rate and pressure And shape information of the members such as the pump and the length and diameter of the pipe, and the like.

The safe operation range 12 can be calculated based on the piping structure information 11 and is the allowable range of the pressure measurement value 121-2.

As described above, the leak prediction and alarm system of the water-purifying water system using the LPWA wireless communication module according to an embodiment of the present invention is constructed in the structure of the piping 110 of the water- It is possible to monitor the leakage phenomenon in the network 100 of the fire-fighting water system 100 by realizing the pressure of the fire-fighting water periodically measured at the node in an intuitive user interface (UI User Interface) There is an advantage that it can be confirmed.

3, a pressure calculation algorithm 410 for calculating a pressure prediction value 411-1 at a specific position 121-1 based on the piping measurement information 121 and the piping structure information 11 It is possible to further include an associative device 400 for generating pipeline prediction information 411 by using the pipeline prediction information 411.

The pressure and the flow rate of the water to be transferred through the pipe 110 can be calculated mathematically based on the shape information of the pipe 110.

The pressure calculation algorithm 410 constituting the associating apparatus 400 is configured to calculate the pressure of each node based on the pipe structure information 11 and the pipe measurement information 121, The pipe prediction information 411 including the pressure prediction value 411-1 in the pipe 121-1 can be calculated. That is, by using the pressure measurement value 121-2 measured at a specific time 121-3 and the characteristic information such as the shape, structure, and material of the pipe 11 included in the pipe structure information 11, The time pressure measurement value can be predicted.

The pressure prediction value 411-1 may be transmitted to the UI processing unit and included in the UI information together with the pressure measurement value 121-2 so as to be displayed on the UI display unit. That is, the pressure measurement value 121-2 measured at a specific time 121-3 at t = t1 | _{t = t1} is the pressure measurement value 121-2 measured at a specific time 121-3 of t = t0 | _the manager 10 can be notified by being displayed on the UI display unit simultaneously with the predicted value calculated based on _{t = t0} .

At this time, when the pressure calculation algorithm 410 of the computing device 400 is synchronized with the symbols corresponding to the pipes constituting the pipe 110, the connecting pipe, the nozzle and the members of the pump, When the structure information 11 is changed, the pressure prediction value 411-1 may be calculated again based on the changed pipe structure information 11 and displayed on the UI display unit.

When the fire water is sprayed using a sprinkler or fire hydrant at the point of fire, the pressure distribution of the pipe 110 network of the entire fire fighting water system is changed. Therefore, by predicting the pressure change by simulating the change of the pipe 110, it is possible to smoothly and effectively cope with the occurrence of the actual topic.

Therefore, by combining the intuitive U.I. and the pressure calculation algorithm 410, it is possible to function as a network pressure simulator of the piping 110 that can predict the pressure of various piping 110 networks in an emergency.

By providing the gateway 500, it is possible to receive data such as pipe measurement information from the communication module and connect the pressure sensor unit 120 to one IoT device in a communication network of another protocol.

That is, the information generated by the pressure sensor unit 120 can be connected to the Internet, and the manager 10 executes the mobile-type monitoring apparatus 300 implemented as an app in a mobile terminal including a smart phone, The degree of freedom of the behavior radius of the manager 10 and the multiple management can be made possible by managing the pressure sensor unit 120 installed in the water purification facility for fire fighting.

That is, the various members constituting the pipe 110 can derive a unique pressure calculation formula according to their shapes and sizes. By modularizing the pressure calculation formula according to the pressure member, The pressure value can be calculated.

By providing pressure prediction according to the degree of operation of members that actively influences the pressure, such as nozzles and pumps, it is possible to supply a desired pressure flow rate to a sprinkler or fire hydrant installed at a specific point in the piping 110 network when a fire occurs It is possible to adjust the operation of the piping 110 necessary for the operation.

5 is an operation block diagram of a U.I processing unit and a U.I. display unit applied to a leak prediction and alarm system of a water purifier for a fire fighting system using the LPWA wireless communication module according to an embodiment of the present invention.
