Description

Monitoring system for sprinkler piping and method of operation therefor

[0001] The present specification relates to a monitoring system for sprinkler pipes and an operating method therefor, and more particularly, to a monitoring system for sprinkler pipes capable of detecting the location of aged pipes and generating a pipe replacement alarm signal according to the internal pressure state of the pipes as well as performing automatic distribution of an eco-friendly corrosion inhibitor based on the pH state of the sprinkler pipes detected using a plurality of complex sensor devices, and an operating method therefor.

[0002] Corrosion can be prevented by eliminating one element of the corrosion triangle: water, air, and metal. Sprinkler systems come in several implementation methods: dry, wet, pre-action, blast, and negative pressure. Each method differs in terms of installation, operating principles, and maintenance.

[0003] For example, wet sprinklers are systems where the pipes are constantly filled with water, and when a fire occurs, the sprinkler head ruptures due to heat, releasing water. Similarly, negative pressure sprinklers are systems where the pipes are filled with both water and air, and when a fire occurs, the air is released, releasing water.

[0004] Meanwhile, pre-action sprinklers are linked to fire detectors. Normally, the pipes are empty, but water is supplied through them when a fire is detected. Furthermore, simultaneous-action sprinklers operate simultaneously, with all sprinklers operating when a fire is detected, even though the pipes are normally empty.

[0005] For a previous proposal, please refer to Korean Patent No. 10-2101625, which discusses an 'ICT integrated monitoring water management system for building a smart water city.'

[0006] The purpose of the present specification is to provide a monitoring system for sprinkler pipes and an operating method therefor that can detect the location of aged pipes and generate a pipe replacement alarm signal according to the internal pressure state of the pipes as well as perform automatic distribution of an eco-friendly corrosion inhibitor according to the pH state of the sprinkler pipes detected using a plurality of complex sensor devices.

[0007] The technical tasks to be achieved through this specification are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by a person having ordinary skill in the technical field to which this specification pertains from the description below.

[0008] In one embodiment, an operating method for a monitoring system for sprinkler piping comprises the steps of: receiving, from a first composite sensor device, first identification information indicating a first composite sensor device associated with a first installation location and first pipe condition information measured by the first composite sensor device, wherein the first pipe condition information includes a first pH measurement value and a first internal pressure value for a first pipe section associated with the first installation location; receiving, from a second composite sensor device, second identification information indicating a second composite sensor device associated with a second installation location and second pipe condition information measured by the second composite sensor device, wherein the second pipe condition information includes a second pH measurement value and a second internal pressure value for a second pipe section associated with the second installation location; detecting a pH abnormality for sprinkler piping based on the first pH measurement value and the second pH measurement value; A step of transmitting a control signal to an automatic distribution device instructing injection of an environmentally friendly corrosion inhibitor into at least one pipe section where a pH abnormality is detected when at least one pH value is determined to be outside a preset first threshold range based on the first pH measurement value and the first pH measurement value.

[0009] According to the present embodiment, the environmentally friendly corrosion inhibitor corresponds to a silicate-based corrosion inhibitor, and at least one piping section is characterized in that it is determined based on the first identification information and the second identification information.

[0010] According to the present embodiment, the method further comprises the step of detecting pipe aging for the sprinkler pipe based on the first internal pressure value and the second internal pressure value when it is determined that at least one pH value does not fall outside the first threshold range.

[0011] According to the present embodiment, the method further includes a step of generating replacement alarm information for at least one pipe section among the first pipe section and the second pipe section in which aging is detected when at least one internal pressure value is determined to be outside a preset second threshold range based on the first internal pressure value and the second internal pressure value.

[0012] A monitoring system for sprinkler piping according to the present embodiment comprises a plurality of composite sensor devices associated with a plurality of installation locations of sprinkler piping;

[0013] At least one relay device for individually receiving a plurality of pipe status information and a plurality of identification information from the plurality of composite sensor devices; an automatic distribution device implemented to store and supply an eco-friendly corrosion inhibitor; and an integrated control server that is connected to the at least one relay device and the automatic distribution device through a pre-established network, wherein the integrated control server is implemented to detect a pH abnormality for a sprinkler pipe based on a plurality of pH measurement values ​​included in the plurality of pipe status information, and is implemented to transmit a control signal to the automatic distribution device for instructing injection of an eco-friendly corrosion inhibitor into at least one pipe section in which a pH abnormality is detected when at least one pH value is determined to be out of a first threshold range set in advance based on the plurality of pH measurement values.

[0014] According to one embodiment of the present specification, a monitoring system for sprinkler pipes and an operating method therefor can be provided that can detect the location of aged pipes and generate a pipe replacement alarm signal according to the internal pressure state of the pipes as well as automatically distribute an eco-friendly corrosion inhibitor based on the pH state of the sprinkler pipes detected using a plurality of composite sensor devices.

[0024] The aforementioned characteristics and the detailed description below are all exemplary, intended to aid in the explanation and understanding of this specification. That is, this specification is not limited to these embodiments and may be embodied in other forms. The following embodiments are merely examples intended to fully disclose this specification and are intended to convey the disclosure of this specification to those skilled in the art. Therefore, if there are multiple methods for implementing the components of this specification, it is necessary to clarify that this specification can be implemented using any of these methods, either a specific one or an equivalent one.

[0025] When this specification refers to a configuration as including specific elements, or a process as including specific steps, it implies that other elements or steps may also be included. In other words, the terminology used herein is intended only to describe specific embodiments and is not intended to limit the concepts of this specification. Furthermore, examples described to aid understanding of the invention also include complementary embodiments.

[0026] The terms used in this specification have the meanings commonly understood by those skilled in the art to which this specification pertains. Commonly used terms should be interpreted consistently within the context of this specification. Furthermore, terms used in this specification should not be interpreted in an overly idealistic or formal sense unless their meanings are clearly defined. Embodiments of this specification are described below with reference to the accompanying drawings.

[0027] Figure 1 illustrates an example of a sprinkler pipe to which a monitoring system according to the present embodiment is applied.

[0028] Referring to FIG. 1, one or more sprinkler pipes to which the monitoring system according to the present embodiment is applied can be implemented to receive water and an eco-friendly corrosion inhibitor from the tank (10) according to the opening and closing operation of one or more valves (13) connecting one or more pipe sections (12) corresponding to the water channel and the tank (10).

[0029] For example, according to the present embodiment, one or more pipe sections (12) for sprinkler pipes may be arranged on each floor (1F, B1F) of a building.

[0030] In this case, water (i.e., fire extinguishing water) and an eco-friendly corrosion inhibitor can be supplied from the tank (10) to one or more pipe sections (12) of each floor (1F, B1F) according to the opening and closing operation of one or more valves (13).

[0031] Additionally, a plurality of sprinklers (11) provided on one or more pipe sections (12) can be implemented to spray water (i.e., fire extinguishing water) supplied through one or more pipe sections (12) to the surroundings.

[0032] Additionally, a plurality of sprinklers (11) can be connected to an automatic distribution device (not shown) storing an environmentally friendly corrosion inhibitor through one or more pipe sections (12) and one or more valves (13).

[0033] For example, a plurality of composite sensor devices (110_1, 110_2) can be coupled to pre-equipped installation locations (P1, P2) on one or more pipe sections (12) for sprinkler pipes of each floor (1F, B1F).

[0034] In this case, each of the plurality of composite sensor devices (110_1, 110_2) can be implemented to transmit its own identification information and pipe condition information measured at the corresponding installation location (P1, P2) to a relay device (120) through a pre-established wireless (or wired) connection.

[0035] For example, the relay device (120) can control the opening and closing of one or more valves (13) according to a command from the integrated control server (130).

[0036] In other words, the relay device (120) can be implemented to individually fully open one or more valves (13), individually completely block one or more valves (13), or individually adjust the degree of opening of one or more valves (13) according to a command from the integrated control server (130).

[0037] Meanwhile, although not shown in FIG. 1, the relay device (120) can be implemented to mix (or inject) an eco-friendly corrosion inhibitor into water (i.e., fire extinguishing water) sprayed from multiple sprinklers (11) by opening a valve connected to an automatic distribution device (not shown) according to a command from an integrated control server (130).

[0038] For example, the relay device (120) can be understood as a gateway for supporting data transmission and reception between a plurality of complex sensor devices (110_1, 110_2) and an integrated control server (130) based on a network (NW).

[0039] Here, the network (NW) can be pre-established based on at least one of a wired network or a wireless network based on LTE, 5G or Wi-Fi communication protocols.

[0040] For example, the integrated control server (130) can be implemented based on a cloud server.

[0041] For example, based on the detection results of multiple composite sensor devices (110_1, 110_2) by the integrated control server (130), it may be determined that additional injection of an eco-friendly corrosion inhibitor is necessary toward the first pipe section (12) associated with the first installation location (P1).

[0042] In this case, the integrated control server (130) can transmit a control signal to the relay device (120) instructing the opening of a valve located between an automatic distribution device (not shown) storing an eco-friendly corrosion inhibitor and a first pipe section (12) associated with the first installation location (P1).

[0043] Next, the relay device (120) can be implemented to control a valve located between an automatic distribution device (not shown) and a first pipe section (12) associated with a first installation location (P1) according to a control signal corresponding to an opening command, thereby injecting an environmentally friendly corrosion inhibitor onto the first pipe section (12) associated with a specific location (P1).

[0044] In addition, aging of the pipe can be detected at a specific location (P1) based on the detection results of multiple composite sensor devices (110_1, 110_2) by the integrated control server (130).

[0045] In this case, the integrated control server (130) can be implemented to transmit pipe aging grade information and pipe replacement alarm information to an administrator terminal (not shown).

[0046] For example, pipe aging grade information can be understood as information output by a pre-equipped artificial intelligence learning model that inputs one or more internal pressure values ​​associated with pipe aging.

[0047] Here, the pre-built artificial intelligence learning model can be associated with the Support Vector Machine (SVM) algorithm.

[0048] Figure 2 shows a conceptual diagram for an environmentally friendly corrosion inhibitor injected into sprinkler piping according to an embodiment of the present invention.

[0049] Referring to FIGS. 1 and 2, one or more pipe sections (22) of FIG. 2 may correspond to one or more pipe sections (12) for sprinkler pipes of each floor (1F, B1F) of FIG. 1.

[0050] One or more of the pipe sections (22) of FIG. 2 may include an environmentally friendly corrosion inhibitor according to the present embodiment.

[0051] For example, the environmentally friendly corrosion inhibitor included in one or more pipe sections (22) of FIG. 2 may be a silicate-based corrosion inhibitor.

[0052] Specifically, the cathodic monomer (SiO3), which is the main component of silicate corrosion inhibitors, 2- ) is a copper cation (Cu) generated by oxidation reaction at the anode area inside the copper tube. 2+ ) reacts with a protective monomolecular film (Mono molecule, CuO·Si(OH) 3+ ) can suppress the oxidation reaction at the anode.

[0053] In addition, when a single molecular film of the same type is formed at the anode, the cathodic monomer (SiO3) in the corrosion inhibitor 2- ) is a highly insulating anion membrane (SiO3 2- This is the principle of effectively blocking the oxidation reaction of the anode by forming a film.

[0054] For example, the principle of the silicate-based corrosion inhibitor according to the present embodiment is as shown in the following chemical formula 1.

[0055]

[0056] FIG. 3 shows a block diagram for a monitoring system for sprinkler piping according to one embodiment of the present invention.

[0057] Referring to FIGS. 1 to 3, a monitoring system (100) for sprinkler piping according to the present embodiment may include a plurality of complex sensor devices (310), a relay device (320), an integrated control server (330), and an automatic distribution device (340).

[0058] A plurality of composite sensor devices (310) of FIG. 3 can be coupled to a plurality of predetermined installation locations (e.g., P1, P2 of FIG. 1) on one or more pipe sections (e.g., 12 of FIG. 1) for sprinkler pipes provided for each floor (e.g., 1F, B1F of FIG. 1) (or for each section) of FIG. 1.

[0059] For example, each of the plurality of composite sensor devices (310) may be implemented to generate pipe condition information and identification information measured at its own installation location (e.g., P1, P2 in FIG. 1).

[0060] For example, the pipe condition information may correspond to data measured by a plurality of sensor modules included in a composite sensor device (310), and the plurality of sensor modules are described in more detail with reference to FIG. 4 described below.

[0061] The relay device (320) of FIG. 3 can control multiple pipe status information and identification information received from multiple complex sensor devices (310) to be transmitted to the integrated control server (330) via the network (NW).

[0062] In addition, the relay device (320) can control the opening and closing operation of a valve (e.g., 13 in FIG. 1) on one or more pipe sections (12) for sprinkler pipes of each floor (e.g., 1F, B1F in FIG. 1) according to a control signal received from the integrated control server (330).

[0063] The integrated control server (330) of FIG. 3 can perform a pH abnormality detection function and an aging detection function for sprinkler pipes of each floor (e.g., 1F, B1F of FIG. 1) based on a plurality of pipe status information and a plurality of identification information received from a plurality of complex sensor devices (310).

[0064] For example, the integrated control server (330) is implemented based on a cloud server and can be linked with the administrator terminal (30).

[0065] The automatic distribution device (340) of FIG. 3 is configured to store the eco-friendly corrosion inhibitor of the present specification, and can be implemented to additionally inject the eco-friendly corrosion inhibitor into a specific location of the sprinkler pipe provided for each floor (e.g., 1F, B1F of FIG. 1) (or for each section) under the control of the integrated control server (330).

[0066] Figure 4 shows a block diagram for a composite sensor device according to an embodiment of the present invention.

[0067] Referring to FIGS. 1 to 4, the composite sensor device (400) of FIG. 4 may correspond to any one of the plurality of composite sensor devices (310_1 to 310_M) of FIG. 3.

[0068] For example, the composite sensor device (400) may include a TDS sensor module (410), a pH sensor module (420), a dissolved oxygen sensor module (430), a water temperature sensor module (440), a heat detection sensor module (450), and a smoke sensor module (460).

[0069] For example, the TDS (Total Dissolved Solids) sensor module (410) may be configured to measure the total amount of ions dissolved in water in units of mg / L or ppm.

[0070] Here, the TDS sensor module (410) can generate sensing data according to the measured amount of metal ions such as calcium and magnesium in the digester water filled in the pipe associated with the installation location where the complex sensor device (400) is installed.

[0071] For example, the pH sensor module (420) may be configured to measure the acidity and alkalinity of ions dissolved in water as a number between 0 and 14.

[0072] Here, the pH sensor module (420) can generate sensing data (i.e., pH measurement value) according to the measured ratio of hydrogen ions and hydroxide ions of the digested water filled in the pipe associated with the installation location where the composite sensor device (400) is installed.

[0073] For example, the dissolved oxygen sensor module (430) may be configured to measure the amount of oxygen dissolved in the digester water filled in a pipe associated with the installation location where the composite sensor device (400) is installed.

[0074] Here, the amount of oxygen dissolved in the fire extinguishing water charged into the sprinkler pipe by the dissolved oxygen sensor module (430) can be related to whether a hole occurs on the surface of the pipe.

[0075] According to the present embodiment, the composite sensor device (400) can be implemented to include sensing data (i.e., pH measurement value) measured by the pH sensor module (420) in the pipe status information and transmit it to the integrated control server (e.g., 330 of FIG. 3).

[0076] According to the present embodiment, the composite sensor device (400) may be implemented to perform data processing on a set of sensing data acquired from a TDS sensor module (410), a pH sensor module (420), and a dissolved oxygen sensor module (430) to generate more accurate pH status information of the extinguishing water filled in the sprinkler pipe, and to include the acquired information in the pipe status information and transmit it to an integrated control server (e.g., 330 of FIG. 3).

[0077] For example, the water temperature sensor module (440) may be configured to measure the water temperature of fire extinguishing water filled in the sprinkler pipe.

[0078] For reference, the water temperature sensor module (440) can be implemented to satisfy all IPC standards, as both the detection circuit and PCB must be placed inside the pipe to measure the water temperature.

[0079] Here, the water temperature sensor module (440) can be manufactured as an integral part with a water pressure sensor (not shown). In addition, through sensing data measured by the water temperature sensor module (440), it is possible to prevent pipe bursting when the fire extinguishing water filled with water freezes due to a drop in the ambient temperature, or to prevent in advance a decrease in the fire extinguishing effect of water (i.e., fire extinguishing water) due to an increase in water temperature.

[0080] Here, a composite sensor device (400) measured by a water pressure sensor (not shown) can generate sensing data (i.e., an internal pressure value) according to the internal pressure of the fire extinguishing water filled in the pipe associated with the installation location.

[0081] According to this embodiment, the water temperature sensor module (440) and the water pressure sensor (not shown) can be understood as a configuration for measuring the degree of aging of the pipe associated with the installation location where the composite sensor device (400) is installed.

[0082] For example, the thermal detection sensor module (450) may be configured to measure the temperature of a pipe associated with the installation location where the composite sensor device (400) is installed.

[0083] Here, if the temperature of the pipe measured by the heat detection sensor module (450) exceeds a preset threshold value, the heat detection sensor module (450) can generate an alarm signal to notify of a fire outbreak.

[0084] For example, the smoke sensor module (460) may be configured to measure the amount of smoke around the pipe associated with the installation location where the sprinkler's composite sensor device (400) is installed.

[0085] Here, if the amount of smoke generated around the pipe measured by the smoke sensor module (460) exceeds a preset threshold value, the smoke sensor module (460) can generate an alarm signal to notify of a fire outbreak.

[0086] According to the present embodiment, a plurality of sensor modules (410 to 460) included in the composite sensor device (400) may be arranged within one housing or may be arranged at independent locations with respect to the sprinkler piping.

[0087] Figure 5 shows a block diagram for a relay device according to an embodiment of the present invention.

[0088] Referring to FIGS. 1 to 5, the relay device (500) of FIG. 5 may correspond to the relay device (320) of FIG. 3.

[0089] The relay device (500) of FIG. 5 may include a central operation board (510), a plurality of side board modules (520_1 to 520_m), and a plurality of relay board modules (530_1 to 530_n).

[0090] For example, the central operation board (510) may be a configuration that controls the overall operation of the relay device (500). In this case, the central operation board (510) may be implemented based on a microcontroller.

[0091] The first to Mth side board modules (520_1 to 520_m, where m is a natural number) of FIG. 5 can be understood as a type of board jig that performs the role of fixing a PCB board inside the housing of the relay device (500).

[0092] In this case, the first to Mth side board modules (520_1 to 520_m) are inserted into the edge of the PCB board to not only accurately maintain the position of the PCB board but also prevent damage or malfunction due to vibration.

[0093] For example, the first to Mth side board modules (520_1 to 520_m) may be implemented to be linked with at least one sensor module (e.g., 410, 420, 430, 440 of FIG. 4) associated with pH detection and aging detection among the plurality of sensor modules included in the aforementioned composite sensor device (e.g., 400 of FIG. 4).

[0094] Additionally, the cable loop circuit of FIG. 6, which will be described later, can be individually applied between the first to M side board modules (520_1 to 520_m) and at least one sensor module associated with pH detection (e.g., 410, 420, 430 of FIG. 4).

[0095] Likewise, the cable loop circuit of FIG. 6, which will be described later, can be individually applied between the first to Mth side board modules (520_1 to 520_m) and at least one sensor module (e.g., 440 of FIG. 4) associated with detection of aging of the pipe.

[0096] For example, the cable loop circuit of FIG. 6 may be applied between the first side board module (520_1) and the TDS sensor module (e.g., 410 of FIG. 4).

[0097] For example, the cable loop circuit of FIG. 6 can be applied between the second side board module (520_2) and the pH sensor module (e.g., 420 of FIG. 4).

[0098] For example, the cable loop circuit of FIG. 6 may be applied between the third side board module (520_3) and the dissolved oxygen sensor module (e.g., 430 of FIG. 4).

[0099] For example, the cable loop circuit of FIG. 6 may be applied between the fourth side board module (520_4) and the water temperature sensor module (e.g., 440 of FIG. 4).

[0100] The first to Nth relay board modules (530_1 to 530_n, where n is a natural number) of FIG. 5 may be implemented to be linked with at least one sensor module (e.g., 450, 460 of FIG. 4) associated with fire detection among the plurality of sensor modules included in the aforementioned composite sensor device (e.g., 400 of FIG. 4).

[0101] Additionally, the inspection circuit of FIG. 7, which will be described later, can be individually applied between the first to Nth relay board modules (530_1 to 530_n) and at least one sensor module associated with fire detection (e.g., 450, 460 of FIG. 4).

[0102] For example, the inspection circuit of FIG. 7 can be applied between the first relay board module (530_1) and the thermal detection sensor module (e.g., 450 of FIG. 4).

[0103] For example, the inspection circuit of FIG. 7 may be applied between the second relay board module (530_2) and the smoke sensor module (e.g., 460 of FIG. 4).

[0104] FIG. 6 is an exemplary diagram of a cable loop circuit applied to a monitoring system for sprinkler piping according to the present embodiment.

[0105] Referring to FIGS. 1 to 6, it will be understood that the reliability of the operation of the monitoring system for sprinkler piping according to the present embodiment can be improved through application of the structure of the cable loop circuit (600) of FIG. 6.

[0106] For example, the structure of the cable loop circuit (600) of FIG. 6 can be applied between the central operation board (610) and the first side board module (620_1) to ensure normal operation of the TDS sensor module (e.g., 410 of FIG. 4).

[0107] As another example, although not shown in FIG. 6, the structure of the cable loop circuit (600) can be applied between the central operation board (e.g., 510 in FIG. 5) and the second side board module (e.g., 520_2 in FIG. 5) to ensure normal operation of the pH sensor module (e.g., 420 in FIG. 4).

[0108] As another example, although not shown in FIG. 6, the structure of the cable loop circuit (600) can be applied between the central operation board (e.g., 510 in FIG. 5) and the third side board module (e.g., 520_3 in FIG. 5) to ensure normal operation of the dissolved oxygen sensor module (e.g., 430 in FIG. 4).

[0109] As another example, although not shown in FIG. 6, the structure of the cable loop circuit (600) can be applied between the central operation board (e.g., 510 in FIG. 5) and the fourth side board module (e.g., 520_4 in FIG. 5) to ensure normal operation of the water temperature sensor module (e.g., 440 in FIG. 4).

[0110] Meanwhile, the cable loop circuit (600) according to the present embodiment is not limited to the structure of FIG. 6, and any one of various structures known in the art may be applied.

[0111] FIG. 7 is an exemplary diagram of an inspection circuit applied to a monitoring system for sprinkler piping according to the present embodiment.

[0112] Referring to FIGS. 1 to 7, when a first input signal (IN_1) is applied to the inspection circuit (700) of FIG. 7, it is determined whether a first output signal (OUT_1) is properly output, thereby ensuring the reliability of the operation of at least one sensor module (e.g., 450, 460 of FIG. 4) associated with fire detection.

[0113] For example, the first input signal (IN_1) of the inspection circuit (700) of FIG. 7 may correspond to +3.3 V, +5 V, and +24 V.

[0114] For example, although not shown in FIG. 7, the structure of the inspection circuit (700) can be applied bidirectionally between the central operation board (e.g., 510 in FIG. 5) and the first relay board module (e.g., 530_1 in FIG. 5) to ensure normal operation of the thermal detection sensor module (e.g., 450 in FIG. 4).

[0115] As another example, although not shown in FIG. 7, the structure of the inspection circuit (700) can be applied bidirectionally between the central operation board (e.g., 510 in FIG. 5) and the second relay board module (e.g., 530_2 in FIG. 5) to ensure normal operation of the smoke sensor module (e.g., 460 in FIG. 4).

[0116] FIG. 8 is a flowchart illustrating an operation method of a monitoring system for sprinkler piping according to an embodiment of the present invention.

[0117] For a clear and concise understanding of the present embodiment, it is assumed that a normal operating state is such that no fire is detected by some sensor modules (e.g., 450 and 460 in FIG. 4) responsible for the fire detection function of a plurality of composite sensor devices (e.g., 310_1 to 310_M in FIG. 3) installed in a sprinkler pipe.

[0118] Referring to FIGS. 1 to 8, in step S810, a monitoring system for sprinkler pipes according to the present embodiment (e.g., 300 of FIG. 3) can receive a plurality of pipe status information and a plurality of identification information measured by a plurality of composite sensor devices (e.g., 310_1 to 310_M of FIG. 3).

[0119] For example, the plurality of pipe condition information may include pH measurement values ​​and internal pressure values ​​individually measured at locations where a plurality of composite sensor devices (e.g., 310_1 to 310_M in FIG. 3) are installed.

[0120] For example, the plurality of identification information may be information for individually identifying a plurality of composite sensor devices (e.g., 310_1 to 310_M in FIG. 3).

[0121] For example, a relay device (e.g., 320 in FIG. 3) may be installed at a first installation location (e.g., P1 in FIG. 1) of a sprinkler pipe, and may receive first pipe condition information for a first pipe section (e.g., 12 in FIG. 1) associated with the first installation location (e.g., P1 in FIG. 1) from the first composite sensor device (e.g., 310_1 in FIG. 3) along with first identification information indicating the first composite sensor device (e.g., 310_1 in FIG. 3).

[0122] In this case, the first pipe condition information may include a first pH measurement value and a first internal pressure value measured at a first installation location (e.g., P1 in FIG. 1).

[0123] Similarly, a relay device (e.g., 320 in FIG. 3) may be installed at a second installation location of the sprinkler pipe (e.g., P2 in FIG. 1) and may receive second pipe condition information for a second pipe section (e.g., 12 in FIG. 1) associated with the second installation location (e.g., P2 in FIG. 1) from the second composite sensor device (e.g., 310_2 in FIG. 3) along with second identification information indicating the second composite sensor device (e.g., 310_2 in FIG. 3).

[0124] In this case, the first pipe condition information may include a second pH measurement value and a second internal pressure value measured at a second installation location (e.g., P2 in FIG. 1).

[0125] Next, the integrated control server (e.g., 330 in FIG. 3) can receive multiple pipe status information and multiple identification information from a relay device (e.g., 320 in FIG. 3) via a pre-established network (e.g., NW in FIG. 3).

[0126] At step S820, the monitoring system for sprinkler pipes according to the present embodiment (e.g., 300 of FIG. 3) can detect a pH abnormality in the sprinkler pipes based on a plurality of pH measurement values ​​included in a plurality of pipe status information.

[0127] For example, the integrated control server (e.g., 330 in FIG. 3) may determine that the first pH value obtained from the first composite sensor device (e.g., 310_1 in FIG. 3) installed at the first installation location (e.g., P1 in FIG. 1) indicated by the first identification information is outside the preset first threshold range.

[0128] In this case, the integrated control server (e.g., 330 in FIG. 3) can determine that a pH abnormality has occurred in the pipe section associated with the location (e.g., P1 in FIG. 1), and the procedure proceeds to step S830.

[0129] For another example, the integrated control server (e.g., 330 in FIG. 3) may determine that a first pH measurement value obtained from a first composite sensor device (e.g., 310_1 in FIG. 3) installed at a specific location (e.g., P1 in FIG. 1) of a sprinkler pipe falls within a preset first threshold range.

[0130] In this case, the integrated control server (e.g., 330 in FIG. 3) can determine that no pH abnormality has occurred in the pipe section associated with the corresponding location (e.g., P1 in FIG. 1) indicated according to the first identification information, and the procedure proceeds to step S840.

[0131] At step S830, the monitoring system for sprinkler piping according to the present embodiment (e.g., 300 of FIG. 3) can transmit a control signal to an automatic distribution device (e.g., 340 of FIG. 3) to inject an environmentally friendly corrosion inhibitor into at least one piping section (e.g., 12 of FIG. 1) associated with at least one location (e.g., P1 of FIG. 1) where an abnormal pH is detected.

[0132] In other words, when a control signal is received by an automatic distribution device (e.g., 340 in FIG. 3) from an integrated control server (e.g., 330 in FIG. 3) through a pre-established network (e.g., NW in FIG. 3), the automatic distribution device (e.g., 340 in FIG. 3) can control an eco-friendly corrosion inhibitor to be injected into a pipe section associated with a location where an abnormal pH is detected (e.g., P1 in FIG. 1).

[0133] At step S840, a monitoring system for sprinkler piping according to the present embodiment (e.g., 300 of FIG. 3) can determine whether piping aging of the sprinkler is detected based on a plurality of internal pressure values ​​included in a plurality of piping status information.

[0134] For example, the integrated control server (e.g., 330 in FIG. 3) may determine that the first internal pressure value obtained from the first composite sensor device (e.g., 310_1 in FIG. 3) indicated by the first identification information is outside the preset second threshold range.

[0135] In this case, the integrated control server (e.g., 330 in FIG. 3) can determine that an aging phenomenon has occurred in the pipe section (e.g., 12 in FIG. 1) associated with the location (e.g., P1 in FIG. 1), and the procedure proceeds to step S850.

[0136] At step S850, the monitoring system for sprinkler piping according to the present embodiment (e.g., 300 of FIG. 3) can generate piping deterioration grade information for one or more installation locations (e.g., P1 of FIG. 1) where piping deterioration has been detected.

[0137] For example, pipe aging grade information can be understood as information output by a pre-equipped artificial intelligence learning model that inputs one or more internal pressure values ​​associated with pipe aging.

[0138] Here, the pre-equipped artificial intelligence learning model can be associated with the SVM algorithm.

[0139] Additionally, the monitoring system for sprinkler piping according to the present embodiment (e.g., 300 of FIG. 3) can generate piping replacement alarm information visualizing one or more installation locations (e.g., P1 of FIG. 1) where piping deterioration is detected.

[0140] In this case, the pipe replacement alarm information can be implemented to be transmitted from the integrated control server (e.g., 330 in FIG. 3) to the administrator terminal (e.g., 30 in FIG. 3) via a pre-established network (e.g., NW in FIG. 3).
