Description

Technology Field

[0001] The present invention relates to an information and communication cable system for multi-unit housing for construction supervision, and more specifically, to an improved information and communication cable system for multi-unit housing for construction supervision that enhances supervision efficiency by inspecting the installation status of information and communication cables installed in multi-unit housing through a cable inspection device, allows multiple processing modules constituting the supervision server to be cooled stably without deterioration, and minimizes human casualties as well as material and property damage by rapidly protecting the server using a fire curtain in the event of a fire. Background Technology

[0002] Generally, the supervision system can be divided into on-site, administrative, and government relations tasks; among these, on-site tasks involve performing frequent construction verification and inspection work according to pre-, during, and post-construction procedures.

[0003] For example, in the case of information and communication construction for multi-unit housing, as construction progresses, the specifications of the information and communication cables installed within the units and the condition of the connector connections are inspected.

[0004] Conventionally, during cable inspections, a supervisor located in the underground telecommunications room of an apartment complex and another supervisor located within the unit to be inspected had to communicate via radio while checking the ends of the cables laid in the telecommunications room and the unit to verify whether there were any abnormalities in the cable installation.

[0005] In other words, there is a problem in that two or more supervisors must be stationed in each household of the apartment complex and in the underground telecommunications room of the apartment complex to personally check the connection status of cables one by one.

[0006] In addition, cables laid from each household are extended and gathered in the communication room of a multi-unit dwelling. However, as the number of households increases, there is a problem in that it is difficult to immediately identify which cable was laid from which household in the communication room.

[0007] Therefore, it is necessary to effectively separate the cables from each household installed in the communication room of an apartment building.

[0008] Meanwhile, since the specifications of cables installed in each household may vary by household according to the design, it is also necessary to perform supervision duties to compare the actual specifications of the installed cables with design information containing related details in order to verify whether construction was carried out in accordance with the design.

[0021] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0022] The information and communication cable system for multi-unit housing for construction supervision according to the present invention utilizes the configuration of prior registered patent No. 2050690 as is.

[0023] Therefore, some of the following descriptions are based on the contents of the aforementioned registered patent.

[0024] As shown in FIG. 1, the information and communication cable system for construction supervision of a multi-unit dwelling according to the present invention comprises: a communication terminal box (170) for each unit that is installed in each unit of the multi-unit dwelling and includes an RFID chip (174) in which unit information is stored; a cable inspection system (100) that includes a portable terminal (110) which is carried by a user who is a supervisor to check the construction status of the cable for each unit and a main body (140) which is placed in the communication room of the multi-unit dwelling and displays the construction status of the cable laid and the unit information of the inspected cable together with the portable terminal (110); and a supervision server (180) that stores design information for each unit, is connected to the portable terminal (110) to transmit the design information for each unit to the portable terminal (110), and receives and stores the inspection results.

[0025] The above-mentioned household communication terminal box (170) installed in each household of a multi-unit dwelling includes a housing (171), a hub (172), a household terminal block (173), and an RFID chip (174).

[0026] The housing (171) is provided with an installation space so that communication equipment, such as a hub (172), can be installed inside.

[0027] In addition, it can be made of a highly durable material to protect internal communication equipment from strong impacts or fire.

[0028] The hub (172) is a device that performs the role of connecting terminals to the network in an Ethernet network and is provided inside the enclosure (171) so that terminals connected to cables laid from within the household can be connected to the network through cables laid to the communication room of the apartment building.

[0029] To this end, a cable for each household must be laid from the household communication terminal box (170) to the communication room of the apartment building.

[0030] Specifically, all cables within the household are laid inside the enclosure (171) and connected to the hub (172), and the household cables laid from the communication room to the enclosure (171) are also connected to the hub (172).

[0031] One end of the cable that is fed into the housing (171) and connected to the hub (172) may be provided with a connector for connecting to the hub (172).

[0032] The generation terminal block (173) is used when the cable is directly connected to a lug or the like rather than a connector standard.

[0033] Communication cables or power lines with a small number of wires can be connected.

[0034] The RFID chip (174) is provided inside the enclosure (171) and stores generation information.

[0035] Household information may include details such as the unit number and location of the household.

[0036] Generation information is provided, such as by the supervisor checking their location through a portable terminal (110).

[0037] For example, the supervisor can determine their location based on generation information obtained from the RFID chip (174).

[0038] The portable terminal (110) includes a first connector connection part (111), a first terminal block (113), an inspection part (114), an RFID reader part (112), and a first communication part (116).

[0039] The portable terminal (110) can be operated to be linked with a mobile phone, smartphone, tablet, laptop, PDA (Personal Digital Assistants), PMP (Portable Multimedia Player), etc.

[0042] In addition, multiple first connector connection parts (111) may include different connection ports in case the generation-specific cables provided in the generation are of different types.

[0043] For example, in addition to the RJ45 connector standard of UTP cables, a connector for RS-232C 9-pin or 25-pin connection standards may also be provided.

[0044] In this way, the first connector connection part (111) may include multiple first connector connection parts (111) with different connection standards so that cables of various connection standards can be connected and inspected.

[0045] The first terminal block (113) is provided to directly connect multiple terminals, such as lug terminals, which are connected to one end of a cable laid in each household.

[0046] The first terminal block (113) is provided so that cable inspection can be performed even when the terminal treatment of the wires is done in a way such as a lug, like a sensor cable or power line with a small number of wires.

[0047] The RFID reader (112) of the portable terminal is configured to read household information stored in the RFID chip (174) provided in the household communication terminal box (170).

[0048] When the supervisor contacts the portable terminal (110) with the RFID chip (174), the RFID reader (112) receives generation information from the RFID chip (174).

[0049] The received generation information is transmitted to the second communication unit (146) of the main body (140) placed in the communication room through the first communication unit (116), and when the inspection begins, the main body (140) can determine which generation each connector connected to the second connector connection unit (141) was installed from.

[0050] In addition, the generation information is also transmitted to the supervision server (180), and the supervision server (180) can transmit design information corresponding to the generation information to the portable terminal (110).

[0051] The inspection unit (114) checks for any abnormalities in the cable connected to the first connector connection unit (111) or the first terminal block (113) in conjunction with the main body (140).

[0052] The inspection unit (114) transmits household information to the second communication unit (146) of the main body (140) located in the communication room through the first communication unit (116) and sends out a cable inspection signal for each wire of the cable connected to the first connector connection unit (111) or the first terminal block (113) to check for any abnormalities in the cable installation.

[0053] The main body (140) can detect a cable inspection signal sent by the portable terminal (110) through the first connector connection part (111) or the first terminal part (113) via the second connector connection part (141) or the second terminal block (143), and transmit the detection result via the second communication part (146), thereby enabling the inspection part (114) of the portable terminal (110) to determine whether there is an abnormality in the cable installation.

[0054] Meanwhile, the portable terminal (110) can transmit household information to the supervision server (180) and receive design information corresponding to the household information from the supervision server (180).

[0055] The supervisor can easily verify the suitability of the cable specifications based on the design information, and the inspection unit (114) can perform a cable inspection based on the design information, and when the inspection is finished, the inspection results including household information can be transmitted to the supervision server (180).

[0056] The inspection unit (114) can send a cable inspection signal, consisting of a specific voltage, to the cable connected to the portable terminal (110) to check for miswiring, open circuit, short circuit, etc. of the connector on the connected cable in order to determine whether there is an abnormality in the construction of the cable.

[0057] Specifically, the inspection unit (114) applies voltage to each pin or each terminal of the connector connected to one end of the cable connected to the first connector connection unit (111) or the first terminal block (113), and the main body (140) placed in the communication room detects voltage from the second connector connection unit (141) or the second terminal block (143) and can transmit the result to the inspection unit (114) of the portable terminal (110) through the second communication unit (146).

[0058] By sequentially applying voltage to each pin or terminal, it is possible to check for any abnormalities such as miswiring of each pin of the connector, or open circuits or short circuits in the cable wires. When the portable terminal (110) notifies the main body (140) placed in the communication room to start the inspection, the main body (140) short-circuits each pin or terminal at the second connector connection part (141) or the second terminal block (143), and the portable terminal (110) detects whether there is a short circuit between each pin or terminal at the first connector connection part (111) or the first terminal block (113) to check for any abnormalities such as miswiring of the connector, open circuits or short circuits in the cable wires.

[0059] The main body (140), which is placed in the communication room of a multi-unit building and performs cable inspection together with a portable terminal (110), includes a second communication unit (146), a second connector connection unit (141), a second terminal block (143), and a display unit (145).

[0060] The main body (140) may separately be equipped with a control unit that controls each component and performs cable inspection through interaction with the inspection unit (114) of the portable terminal (110), but in the present invention, it is described as being included in the function of the main body (140).

[0061] The main body (140) receives generation information and whether to start a cable inspection from the first communication unit (116) of the portable terminal (110) through the second communication unit (146).

[0062] Specifically, the supervisor contacts the portable terminal (110) to the RFID chip (174) within a specific generation to obtain generation information through the RFID reader (112), and the generation information is transmitted to the second communication unit through the first communication unit (116).

[0063] When the inspection unit (114) of the portable terminal (110) sends out a cable inspection signal, such as applying voltage to each pin or each terminal of the connector connected to one end of the cable connected to the first connector connection unit (111) or the first terminal block (113) as described above, the main body (140) can detect this and check for any abnormalities in the cable construction and specifications.

[0064] Cables laid from each household of the apartment complex to the apartment complex communication room are connected to the second connector connection part (141).

[0065] Likewise, cables laid from each household of the apartment complex to the apartment complex communication room are connected to the second terminal block (143).

[0066] If the other end of the cable laid from each generation is connected to a connector standard, it can be connected to the second connector connection part (141), and if it is a lug terminal, it can be connected to the second terminal block (143) to perform cable inspection.

[0067] The display unit (145) of the main body (140) is provided to display the received generation information and the inspection results of the cable that has been inspected.

[0068] The supervision server (180) receives generation information from the portable terminal (110) and transmits design information of the corresponding generation to the portable terminal (110).

[0069] Design information may include information such as the specifications of cables installed in the household and cable installation sections.

[0070] The supervision server (180) can provide information such as cable specifications to the portable terminal (110) so that the field supervisor can immediately check whether the cable specifications installed in the household match.

[0071] In addition, the supervision server (180) can store household information, cable specifications and inspection results for each household, inspection date, inspection time, supervisor information, etc.

[0072] The supervision server (180) helps the supervisor write inspection result reports, etc. The supervision server (180) receives supervisor information, etc. from the portable terminal (110) and enables the supervision report to be written.

[0073] The portable terminal (110), the main body (140), and the supervision server (180) can operate based on a network connecting them.

[0074] Here, the term "network" may refer to a medium that performs the role of connecting the portable terminal (110), the main body (140), and the supervision server (180).

[0075] For example, the network can provide a connection path so that the portable terminal and the main body (140) can transmit and receive data after connecting to the supervision server.

[0076] Networks can be configured regardless of communication methods, such as wired and wireless, and can be composed of various wired and wireless communication networks, including wireless networks such as terrestrial mobile communication networks (3G, 4G, etc.), WiFi, and WiBro, as well as short-range communication networks (PAN; Personal Area Network), local area networks (LAN; Local Area Network), metropolitan area networks (MAN; Metropolitan Area Network), and wide area networks (WAN; Wide Area Network).

[0077] FIG. 2 is a drawing for explaining a cable inspection system (100) for supervising information and communication construction of a multi-unit dwelling according to one embodiment of the present invention.

[0078] The supervisor receives household information from an RFID chip (174) provided in a household-specific communication terminal box (170) provided in each household through the RFID reader (112) of the portable terminal (110).

[0079] The supervisor checks the generation information and connects one end (121) of the generation cable exposed inside the enclosure (171) to the first connector connection part (111) of the portable terminal (110) or to the first terminal block (113).

[0080] At this time, the other end (122) of the household cable is laid out in the communication room of the multi-unit housing and connected to the second connector connection part (141) or the second terminal block (143) of the main body (140) placed in the communication room. Meanwhile, household information is transmitted to the supervision server (180) through the first communication part (116) of the portable terminal (110), and the supervision server (180) transmits the design information of the corresponding household to the portable terminal (110).

[0081] The inspection unit (114) of the portable terminal (110) starts inspecting the cable together with the main body (140) based on design information.

[0082] Specifically, the inspection unit (114) applies voltage to each pin or each terminal of the connector connected to one end of the cable connected to the first connector connection unit (111) or the first terminal block (113), and the main body (140) placed in the communication room detects voltage from the second connector connection unit (141) or the second terminal block (143) and can transmit the result to the inspection unit (114) of the portable terminal (110) through the second communication unit (146).

[0083] Through cable inspection signals, such as sequential voltage application to each pin or terminal, it is possible to check for abnormalities such as miswiring of the connector, open circuit or short circuit of the cable wire.

[0084] Meanwhile, when the portable terminal (110) notifies the main body (140) placed in the communication room to start the inspection, the main body (140) short-circuits each pin or terminal at the second connector connection part (141) or the second terminal block (143), and the portable terminal (110) detects whether there is a short circuit between each pin or terminal at the first connector connection part (111) or the first terminal block (113) to check for abnormalities such as incorrect wiring of the connector, open circuit or short circuit of the cable wire.

[0085] FIG. 3 is a perspective view of a portable terminal (110) according to one embodiment of the present invention.

[0086] Referring to FIG. 3, the portable terminal (110) includes a first connector connection part (111) and a first terminal block (113).

[0090] The camera unit improves supervision efficiency by filming areas within the unit that require supervision.

[0091] Specifically, the supervisor can photograph internal structures of the unit, in addition to the cable installation status.

[0092] At this time, the video captured by the camera unit can be transmitted to the supervision server (180), and the supervision server (180) can provide the supervision performer with a list of items for which photos need to be taken in the supervision work.

[0093] A portable terminal (110) according to one embodiment of the present invention may further include an input unit (not shown) in which a user can directly input generation information.

[0094] The input section may be composed of a keypad, a touchpad, etc. In case the supervisor cannot obtain generation information from the RFID chip (174), the generation information can be entered directly.

[0095] The portable terminal (110) transmits the generation information entered from the input unit to the supervision server (180), and the supervision server (180) transmits the design information of the corresponding generation to the portable terminal (110).

[0096] The portable terminal (110) performs a cable inspection through the inspection unit (114) based on the received design information.

[0097] FIG. 4 is a perspective view of a main body according to one embodiment of the present invention.

[0098] Referring to FIG. 4, the main body (140) includes a second communication unit (146), a second connector connection unit (141), a second terminal block (143), and a display unit (145).

[0106] FIG. 5 is a flowchart illustrating a supervision method using a cable inspection system (100) for supervising information and communication construction of a multi-unit dwelling according to one embodiment of the present invention.

[0107] Referring to FIG. 5, a supervision method using a cable inspection system (100) for supervising information and communication construction in a multi-unit dwelling may include: a step in which a portable terminal (110) of the cable inspection system (100) receives household information from an RFID chip (174) attached to a household communication terminal box (170); a step in which the portable terminal (110) transmits the household information to a supervision server (180); a step in which the supervision server (180) transmits information and communication construction design information corresponding to the household information to the portable terminal (110); a step in which the portable terminal (110) inspects the construction status of a laid cable using the main body (140) of the cable inspection system (100) located in the communication room of the multi-unit dwelling based on the received design information; and a step in which the portable terminal (110) transmits the result of inspecting the construction status of the cable to the supervision server (180).

[0108] Since the above cable inspection system (100) has the same configuration as the cable inspection system described above, the description below will be omitted.

[0109] On the other hand, the supervision server (180) according to the present invention is equipped with a plurality of processing modules for signal processing, computation, storage, and display, and the processing modules are mounted in the form of sub-racks in a server housing (1810) as shown in the example of FIG. 6.

[0110] And, the server housing (1810) is formed in the shape of a square box with an open front, and the open front is configured to be openable and closable by a housing door (1820).

[0111] In addition, a main PCB (1830) is fixed to the inner rear wall of the server housing (1810), and a plurality of processing modules described above are mounted on the main PCB (1830).

[0112] In particular, a space is formed on the rear side of the main PCB (1830), and the rear edge of the main PCB (1830) is sealed by a sealing material (1840), and the sealing material (1840) is fixed to an aluminum plate (1850) that is spaced apart from the rear of the main PCB (1830) in the space.

[0113] In addition, the rear of the aluminum plate (1850) is open, and a plate heat exchanger (1860) is installed in the open portion, wherein one side of the plate heat exchanger (1860) is positioned to be in surface contact with the aluminum plate (1850).

[0114] In addition, external air is circulated through one side of the above plate heat exchanger (1860), and return air, which is circulated and recovered inside the building through the building's air conditioner, is piping connected to flow through the other side.

[0115] In this way, indirect heat exchange occurs, but since the air is not extremely cold, condensation is suppressed while cooling efficiency can be increased.

[0116] In particular, since the main PCB (1830) is indirectly cooled by heat conduction through the aluminum plate (1850), it can be safely cooled without the influence of moisture.

[0117] In addition, for internal circulation and internal discharge, a ventilation hole (1870) is formed through the bottom surface of the server housing (1810), and a one-way damper (1880) is installed in the ventilation hole (1870) to allow outside air to pass only in the direction of inflow, and a screen (1890) is installed in the ventilation hole (1870) to allow outside air to be introduced while being completely filtered.

[0118] In addition, a discharge hole (1910) is formed in the ceiling, and a diaphragm (1920) is installed in the discharge hole (1910) and configured to be open only in the direction of discharge, so that the indoor air and the outdoor air are circulated and supplied and discharged by natural convection to achieve equilibrium.

[0119] In particular, a buffer plate (2000) can be further installed on the bottom surface of the server housing (1810).

[0120] At this time, the cushioning plate (2000) is composed of a lower plate (2100) and an upper plate (2300) that is coupled to the lower plate (2100) via an axle (2200), and a cushioning rubber ring (2400) is fitted onto the axle (2200). The cushioning rubber ring (2400) further includes a V-groove (2410) on its circumference in which the lower plate (2100) and the upper plate (2300) can each be partially fitted so as not to be detached.

[0121] In addition, to enhance the cushioning effect, a cushioning guide groove (2500) is further formed near the bottom dead center of the circumference of the hole formed on the lower plate (2100) and the upper plate (2300) to accommodate the cushioning rubber ring (2400), extending further downward to form a space.

[0122] This is to provide a space where the cushioning rubber ring (2400) can be elastically deformed, thereby increasing the elastic cushioning force.

[0123] Additionally, as shown in the example of FIG. 7, a fireproof curtain unit (3600) is further installed in front of the server housing (1810) where it is installed, so that the server housing (1810) can be protected from fire by closing the fireproof curtain (3690) in the event of a fire.

[0124] This fireproof curtain unit (3600) comprises a pivot member (3620) rotatably installed around a hinge (H) between ceiling materials (3610), a solenoid locker (3630) that supports the lower surface of the pivot member (3620) opposite the hinge (H) and is operated by a supervision server (180), a partition wall (3640) integrally fixed directly below the hinge (H) of the pivot member (3620), a linear rod (3650) installed parallel to the partition wall (3640) with a gap between them, a linear motor (3660) that is assembled to move up and down while passing through the linear rod (3650), is fixed to the upper surface of the pivot member (3620), and is controlled to operate later than the solenoid locker (3630) with a time difference by the supervision server (180), and at one end, the It includes a bottom plate (3680) that is hinged at least once on the bottom surface of the partition wall (3640) and has a fitting hole (3670) formed in the center of the width of the other end into which the linear rod (3650) is inserted, and a fireproof curtain (3690) that is fixed at one end to the pivot piece (3620) and stored on the upper part of the bottom plate (3680) in a folded state.

[0125] That is, by installing a fire curtain (3630) on the lower surface of the rotating member (3620) so that the fire curtain (3630) also unfolds when the rotating member (3620) operates, the flames are prevented from rising and spreading, thereby protecting human lives from heat, flames, and smoke and minimizing human casualties.

[0126] To this end, one end of the fire curtain (3690) is fixed to one side of the lower surface of the above-mentioned pivot piece (3620).

[0127] In this case, to increase the flame retardant and heat-blocking effects, the wider the width of the above-mentioned rotating piece (3620), the better.

[0128] And, a partition wall (3640) is integrally and vertically fixed to one side of the lower surface of the above-mentioned pivot piece (3620), that is, to the side opposite to where one end of the fire curtain (3690) is fixed, and one end of the lower plate (3680) is rotatably hinged to the protruding end of the partition wall (3640).

[0129] In addition, a through hole (3670) is formed at the end opposite the hinge of the lower plate (3680).

[0130] At this time, the lower plate (3680) is a plate-shaped member, and it is preferable that the fitting hole (3670) be formed at the center of the width of the plate.

[0131] In addition, the fire curtain (3690) is folded multiple times and stored in the space created by the partition (3640), and is confined by the bottom plate (3680) so as not to be removed.

[0132] In addition, a linear motor (3660) is fixed to the upper surface opposite the hinge of the pivot member (3620), and a linear rod (3650) that moves in and out by an electrical signal is mounted on the linear motor (3660). The linear motor (3660) is electrically connected to the supervision server (180) and operates according to a control signal. It penetrates the pivot member (3620) and is exposed to the lower side, then is inserted into the fitting hole (3670) of the lower plate (3680) and penetrates.

[0133] Therefore, since the insertion hole (3670) is a hole with a diameter such that the linear rod (3650) is inserted, the bottom plate (3680) must be rotated counterclockwise around the hinge to open, so as long as the linear rod (3650) does not come out, the bottom plate (3680) does not open and can maintain the state in which the linear rod (3650) is inserted while the fire curtain (3690) is completely stored.

[0134] Then, when the supervision server (180) detects the occurrence of a fire and issues a control signal, the solenoid locker (3630) operates to unlock, and accordingly, the rotating piece (3620) rotates and opens, and at the same time, the linear rod (3650) operates and rises through the linear motor (3660).

[0135] Then, as the linear rod (3650) is separated from the bottom plate (3680), the bottom plate (3680) becomes freely movable around the hinge, and at the same time, the restraining force holding the folded fire curtain (3690) is released, so the fire curtain (3690) falls downward due to its own weight and unfolds to form a kind of firewall, thereby protecting the lives behind the firewall from flames or heat.

[0136] This not only protects people but also provides the effect of blocking flames or heat from escaping, being conducted, or being transmitted. Explanation of the symbols
