Description

[Technical field]

[0001] The present invention relates to a facility installation method, a riser unit, and a building. [Background technology]

[0002] Mobile communication terminals such as mobile phones and smartphones can transmit and receive voice and data by wirelessly connecting to base stations located in various places. The higher the frequency of wireless radio waves, the faster the communication speed can be, but the higher the frequency, the shorter the propagation distance. In recent years, 5G (5th generation mobile communication system) has started to spread, and the radio waves used in mobile communication are becoming increasingly higher in frequency. For this reason, for example, in order to realize wireless communication on the upper floors of a high-rise building, it is necessary to install a base station or an alternative relay antenna on each floor of the building (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6482840 Summary of the Invention [Problem to be solved by the invention]

[0004] At a construction site, the main body of the building is usually constructed by joining structural materials such as columns and beams, constructing floor slabs and ceiling slabs, and attaching exterior wall panels, followed by the installation of various auxiliary facilities such as air conditioning equipment, water supply and drainage equipment, electrical equipment, and communication equipment. For this reason, for example, at the construction site of a high-rise building, wireless devices such as walkie-talkies are often used to contact workers on higher floors. However, with the recent spread of IoT (Internet of Things), construction-related equipment using wireless data communication has become widespread at construction sites, and wireless devices that can only make voice calls are insufficient as a communication environment at a construction site. In addition, various auxiliary facilities such as air conditioning equipment are also becoming IoT-based in recent years, so a wireless communication environment may be required to use wireless communication services provided by mobile communication operators (carriers) during the trial operation stage before completion of construction.

[0005] Therefore, an object of the present application is to provide an equipment construction method, a riser unit, and a building that enable wireless communication services of mobile communication carriers to be used even in buildings that are still under construction. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides a riser unit equipped with a coaxial cable for an antenna, and when the riser unit is attached to the structural body of a building, the coaxial cable provided in the riser unit is connected to the communications equipment and antenna installed in the building under construction.

[0007] In detail, the present invention is a method for constructing equipment, comprising the steps of: preparing a riser unit having a length in the vertical direction corresponding to a predetermined number of floors and having coaxial cables for antennas corresponding to the frequency band of a wireless communication service provided by a mobile communication carrier, for the predetermined number of floors; installing communication equipment and antennas in a building under construction for connecting the antennas for the wireless communication service to the communication lines of the mobile communication carrier; and, once the riser unit is attached to the structure of the building, connecting the coaxial cables provided on the riser unit attached to the structure to the communication equipment and antennas.

[0008] With this construction method, even if the building is under construction, once the coaxial cable in the riser unit is connected to the communication equipment and antenna, it becomes possible to use the wireless communication services provided by the mobile communication carrier on each floor of the building. This makes it possible to contact workers on each floor without using the traditional walkie-talkies and other wireless devices, and also makes it possible to use construction-related and other devices that are based on wireless communication, which is becoming more common due to the recent trend towards IoT, within the building even during construction.

[0009] In addition, in the step of preparing the riser unit, a riser unit further provided with an optical cable may be prepared, and in the step of connecting the coaxial cable, the coaxial cable may be connected to the communication equipment via a converter and an optical cable. If the riser unit is provided with an optical cable, the optical cable can be installed in the building simply by attaching the riser unit to the structure, making it easy to install the optical cable in the building.

[0010] The converter may also function as a distributor, and in the step of connecting the coaxial cables, the coaxial cables for a predetermined number of floors may be connected to the distributor. This makes it easier to connect the coaxial cables branching out to each floor to the communication equipment.

[0011] The above-mentioned installation method may further include a step of installing an air conditioning equipment capable of wireless connection to a base station of a mobile communication carrier in a building, and a step of monitoring the air conditioning equipment via an antenna installed in the building. This makes it possible to perform a trial run of the air conditioning equipment before the completion of the building, even if the air conditioning equipment installed in the building is equipment that requires a wireless connection to a base station of a mobile communication carrier.

[0012] The present invention can also be understood from the viewpoint of an object. For example, the present invention may be a riser unit having a length corresponding to a predetermined number of floors in the vertical direction and including coaxial cables of antennas corresponding to the frequency band of a wireless communication service provided by a mobile communication carrier, the length corresponding to the predetermined number of floors.

[0013] Furthermore, the present invention may also be a building that, for example, has a riser unit having a length in the vertical direction corresponding to a predetermined number of floors and is provided with coaxial cables for antennas corresponding to the frequency band of a wireless communication service provided by a mobile communication carrier for the predetermined number of floors, communication equipment for connecting the antenna for the wireless communication service to the communication line of the mobile communication carrier, and an antenna connected to the communication equipment via the coaxial cable. Effect of the Invention

[0014] With the above-described installation method, riser unit, and building, wireless communication services of mobile communication carriers can be used even in buildings that are still under construction. [Brief description of the drawings]

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes an embodiment of the present invention. The embodiment described below is an example of the present invention, and the technical scope of the present invention is not limited to the following aspect.

[0017] FIG. 1 is a diagram showing an example of a usage form of a wireless communication service in a building. In this embodiment, a riser unit 3 and an antenna 4 are installed inside a structure 2 constructed using a crane or the like at a construction site of a building 1, and wireless communication is realized between a mobile communication terminal such as a smartphone carried by a worker 5 and a construction-related work machine 6 using wireless data communication. The antenna 4 is connected to a communication facility 7 of the building 1 through a coaxial cable or the like provided in the riser unit 3, and is connected to a communication line owned by a mobile communication carrier outside the building 1 by wire or wirelessly. Therefore, even if the mobile communication terminal carried by the worker 5 and the construction-related work machine 6 using wireless data communication cannot directly communicate wirelessly with a wireless base station of the mobile communication carrier installed outside the building 1, they can use the wireless communication service of the mobile communication carrier by transmitting and receiving radio waves to and from the antenna 4.

[0018] 1, in this embodiment, the antenna 4 and communication equipment 7 are installed during the construction of the building 1, and these wireless communication equipment are used both during the test run of various incidental equipment such as the ceiling-mounted air conditioners 9 and floor-mounted air conditioners 10 installed in the building 1, and after the building 1 starts operating after completion. Therefore, not only the workers 5 involved in the construction of the building 1 and the work machines 6 used in the construction of the building 1, but also the residents 11 who use the building 1 after completion can use the wireless communication services of the mobile communication carrier by transmitting and receiving radio waves to and from the antenna 4.

[0019] 2 is a diagram showing an example of the riser unit 3. The riser unit 3 has coaxial cables 3A connected to antennas 4 on each floor, various pipes 3B such as water pipes and electric conduits arranged to extend in the vertical direction of the building 1, and floor plates 3C for fastening the pipes 3B together. The floor plates 3C correspond to each floor of the building 1, and also function as the floor surface of each floor within a PS (Pipe Space) prepared in the building 1.

[0020] FIG. 2 illustrates a riser unit 3 having a length equivalent to three floors of the building 1. FIG. 2 also illustrates a riser unit 3 having five pipes 3B. However, the riser unit 3 is not limited to this form. The riser unit 3 may have an appropriate length or number of pipes 3B. The riser unit 3 may also have pipes 3B fastened together by a frame such as a rod instead of a plate-like floor panel 3C.

[0021] The number of coaxial cables 3A provided in the riser unit 3 corresponds to the number of antennas 4 on each floor. Therefore, as shown in FIG. 2, the end of the coaxial cable 3A on the antenna side is arranged at a position corresponding to each floor, and the end on the communication equipment 7 side is arranged at an appropriate position. For example, in the example of FIG. 2, the end of the coaxial cable 3A on the communication equipment 7 side is arranged at the lower part of the riser unit 3, but when a distributor for an antenna line is arranged near a part other than the lower part of the riser unit 3, it is preferable that the end of the coaxial cable 3A on the communication equipment 7 side is arranged at that part. In addition, the coaxial cable 3A may be provided in the riser unit 3 in a state where it is wired in, for example, a conduit so that it can be replaced in the future. If a cable rack is provided in the riser unit 3, the coaxial cable 3A, optical cable, and various other communication lines can be easily provided in the riser unit 3. It is preferable that such communication lines are protected by conduits such as PF pipes. In addition, the upper and lower ends of the optical cables provided in the riser unit 3 are provided with connection means such as connection terminals for connecting to a splice box or the like, so that the optical cables can be easily connected to the optical cables of other riser units 3 after the riser unit 3 is installed in the building 1. It is advisable to keep this in mind.

[0022] In this embodiment, the antenna 4 and the communication equipment 7 are installed in the following order: Figure 3 is a diagram showing an example of the construction process of the building 1.

[0023] In this embodiment, as shown in FIG. 3(A), a structure 2 is constructed using a crane 12 or the like at a construction site of a building 1. Then, as shown in FIG. 3(B), a riser unit 3 is attached to the structure 2 at an appropriate timing while the structure 2 is extending upward. Then, an antenna side end of a coaxial cable 3A provided in the riser unit 3 is connected to an antenna 4 installed on each floor of the building 1. Also, an end of a communication equipment 7 side of the coaxial cable 3A is connected to a communication equipment 7 installed on a lower floor of the building 1. This allows a worker 5 inside the building 1 and a work machine 6 in the building 1 used for the construction of the building 1 to use a wireless communication service of a mobile communication carrier by transmitting and receiving radio waves to and from the antenna 4. Then, as shown in FIG. 3(C), riser units 3 are attached to structure 2 at appropriate times as structure 2 extends upward, and antennas 4 on each floor are connected to coaxial cables 3A, so that wireless communication services of the mobile communication carrier become available from lower floors to higher floors, even within building 1 as structure 2 extends upward.

[0024] FIG. 4 is a diagram showing an example of a system configuration of wireless communication equipment installed in a building 1. For example, as shown in FIG. 4, a coaxial cable 3A is connected to a coaxial converter 3D installed on an appropriate floor of the building 1. An optical cable 3F leading to the communication equipment 7 is connected to the coaxial converter 3D, and the coaxial converter 3D distributes the signal of the optical cable 3F to each coaxial cable 3A. Therefore, the coaxial converter 3D functions both as an opto-electrical converter and as a distributor. Therefore, the coaxial converter 3D is connected to a plurality of coaxial cables 3A arranged on different floors, and thereby functions to collect the coaxial cables 3A for a plurality of floors. Note that if such an optical cable 3F is provided in the riser unit 3 together with the coaxial cables 3A, it is easy to install the optical cable 3F in the building 1.

[0025] The coaxial converter 3D side of the optical cable 3F is connected to the coaxial converter 3D via a splice box 3E. The communication equipment 7 side of the optical cable 3F is connected to an optical converter 7B via a splice box 7C. The optical converter 7B is connected to a carrier radio 7A by a cable. The optical converter 7B is provided with a plurality of connection ports for connecting the optical cable 3F, so that a plurality of optical cables 3F can be connected. Thus, the optical converter 7B functions both as an opto-electrical converter and as a distributor.

[0026] In wireless communication equipment with such a system configuration, each time a riser unit 3 is attached to the structure 2 at an appropriate timing while the structure 2 is extending upward, the coaxial cable 3A of the riser unit 3 is connected to a coaxial converter 3D and an antenna 4 on each floor, and the coaxial converter 3D is connected to the communication equipment 7 by an optical cable 3F. Therefore, each time the structure 2 extends upward and a riser unit 3 is attached to the structure 2, the area within the building 1 where wireless communication services of the mobile communication carrier can be used is gradually expanded.

[0027] In this way, the communication equipment that will be put into use during the construction of Building 1 will be made available by having the riser unit 3 attached to Building 1 and then having power supplied from the temporary construction power source to communication equipment that requires power, such as the coaxial converter 3D. When the construction of Building 1 progresses further and a permanent power source is installed inside Building 1, the power lines of these communication equipment will be reconnected from the temporary construction power source to the permanent power source. It is desirable that the power source for these communication equipment will have been switched from the construction power source to the permanent power source at least during the trial operation of the air conditioning equipment and other stages that are carried out before the completion of Building 1.

[0028] A power line for supplying power to communication equipment requiring power such as the coaxial converter 3D may be attached to the riser unit 3 in a state of being connected to the communication equipment in advance, and then the riser unit 3 is attached to the building 1. In this case, the communication equipment is temporarily attached to the riser unit 3. The power supply side end of the power line attached to the riser unit 3 is connected to a power source after the riser unit 3 is attached to the building 1, or is connected to a power supply equipment such as a distribution board attached to the riser unit 3 in advance before the riser unit 3 is attached to the building 1. When a power supply equipment such as a distribution board is attached to the riser unit 3 in advance and then the riser unit 3 is attached to the building 1, it is desirable to attach the power supply equipment to a portion of each part of the riser unit 3 that corresponds to the installation position of the power supply equipment predetermined in the building 1. The installation position of the power supply equipment predetermined in the building 1 is the installation position of the permanent power supply equipment to be installed in the building 1.

[0029] Since the riser unit 3 has a length equivalent to the length of several floors, it is suitable for mounting a distributor such as a coaxial converter 3D that distributes communication lines to several floors when communication equipment requiring power such as a coaxial converter 3D is mounted in advance on the riser unit 3. However, this embodiment is not limited to this, and for example, communication equipment such as a coaxial converter 3D may be provided at each portion of the riser unit 3 corresponding to each floor. Even in this case, by consolidating one end of a power line connected to these communication equipment at the other end in a specific portion of the riser unit 3, it is possible to distribute power to the communication equipment provided in each portion of the riser unit 3 simply by connecting the power at that portion.

[0030] In this way, when attaching communication equipment such as a coaxial converter 3D to the riser unit 3, it is preferable to store and protect the communication equipment in a weatherproof box or protective vinyl, etc., so that the equipment will not break down even if the riser unit 3 is exposed to wind, rain, etc.

[0031] In the above embodiment, even in the building 1 under construction, it is possible to use the wireless communication service provided by the mobile communication carrier at the time of starting the work of installing various auxiliary facilities such as air conditioning equipment, water supply and drainage equipment, electrical equipment, and communication equipment. Therefore, it is possible to contact workers on higher floors without using wireless devices such as walkie-talkies that have been used in the past. In addition, due to the recent trend toward IoT, construction-related equipment used at construction sites is becoming more and more widespread, and control devices and sensors of various auxiliary facilities such as air conditioning equipment are also being replaced by those that are based on wireless communication from those that are based on wired communication using conventional cables. In this regard, in the above embodiment, it is possible to place an avatar robot at a site where various construction works are being carried out, so that workers can remotely check the situation at the site, or to operate equipment such as air conditioners that are based on such wireless communication in the building 1 before completion and perform a test run. An avatar robot is a robot that can be controlled from a remote location, and is capable of functioning as an alter ego of the operator by incorporating interfaces such as a camera that replaces the operator's vision and a microphone that replaces the operator's hearing.

[0032] In particular, air conditioning equipment undergoes detailed final adjustments and trial runs, since even subtle changes in conditions such as duct routing and damper characteristics can have a variety of effects on the indoor environment. Furthermore, if a monitoring room or similar facility is installed in Building 1 to monitor the air conditioning equipment being constructed in Building 1, even if it is not possible to use wireless communication services from mobile communication carriers within Building 1, it is possible to conduct trial runs in the monitoring room prior to completion via wired communication or a temporary wireless LAN (Local Area Network), etc. However, In the case where such a monitoring room is not installed in Building 1 and the air conditioning equipment installed in Building 1 is monitored from a remote location, In this regard, if the wireless communication service of the mobile communication carrier is unavailable, it may not be possible to perform a test run of the air conditioning equipment before the completion of the building 1. In this regard, in the above embodiment, even before the completion of the building 1, the wireless communication service of the mobile communication carrier is available in the building 1, so that even if a monitoring room is not installed in the building 1 and measurement data such as temperature and humidity of the air conditioning equipment installed in the building 1 is monitored from a remote location, the test run of the air conditioning equipment in the building 1 can be performed before the completion of the building 1. In addition, in the above embodiment, the wireless communication service of the mobile communication carrier is available in the building 1 not only after the completion of the building 1 but also during the test run of the air conditioning equipment during construction or before the completion of the building 1, so that it is possible to continuously monitor the air conditioning equipment in one monitoring room in the case of a remote monitoring mode of the air conditioning equipment installed in the building 1.

[0033] In this way, in the above embodiment, the wireless communication service of the mobile communication carrier can be used in the building 1 not only after the completion of the building 1 but also during the construction and during the trial operation of the air conditioning equipment before the completion. Therefore, for example, in the construction stage as shown in FIG. 1(A), various construction-related tasks that assume the use of wireless communication services, such as monitoring by avatar robots, automatic operation of construction machinery, detection and management of materials and equipment, management of workers, confirmation of construction progress, and calls by smartphones, can be performed. By performing various tasks such as monitoring tasks such as checking the status of the construction site, operation of construction machinery, and management of materials and equipment using means that assume the use of wireless communication services from the middle of the construction of the building 1, it is possible to easily respond to the decrease in the working population and the IoT of equipment, which have become social problems in recent years. In addition, in the trial operation stage of the air conditioning equipment as shown in FIG. 1(B), various tasks related to the trial operation that assume the use of wireless communication services, such as data collection and analysis by various sensors such as temperature and humidity, automatic operation of inspection equipment, and calls by smartphones, can be performed. By collecting data from sensors in the air conditioning equipment using a method that assumes the use of wireless communication services before the completion of building 1, it is possible to properly test run the air conditioning system, which uses highly accurate control by making full use of IoT, etc. Also, in the operation stage of the air conditioning equipment as shown in Figure 1 (C), operation tasks such as data collection and analysis using various sensors such as temperature and humidity, abnormality detection in the air conditioning equipment, lifespan determination, FM / PM (facility management / property management), and building management can be performed using a method that assumes the use of wireless communication services. Facility management refers to the effective use and management of facilities as management resources. Also, property management refers to the management of the entire real estate.

[0034] Incidentally, the coaxial cable 3A, communication equipment 7, and other communication equipment installed within Building 1 will in principle be managed by the owner of Building 1 after completion. Therefore, in order to make the coaxial cable 3A, communication equipment 7, and other communication equipment that will be managed by the owner of Building 1 after completion available for use before completion, the business operator involved in the construction of Building 1 must enter into a contract with a major mobile communication operator or the like to make the coaxial cable 3A and other communication equipment available for use. Therefore, if the owner of Building 1 contracts with a mobile communication operator other than the one that the business operator involved in the construction of Building 1 had contracted with after the completion of Building 1, there is a possibility that the mobile communication operator that can use wireless communication services within Building 1 will change before and after the completion of Building 1.

[0035] In the above embodiment, a mobile communication carrier is assumed to provide wireless communication services outside the building 1. However, the wireless communication services provided within the building 1 by the coaxial cable 3A, the communication equipment 7, and other communication facilities are not limited to public wireless communication services. For example, private LTE (Long Term Evolution) In this case, the entity providing the wireless communication service realized in the building 1 under construction may be, for example, the owner of the building 1, a business entity involved in the construction of the building 1, etc. In the case where the wireless communication service provided within building 1 by communication equipment such as A or communication equipment 7 is a non-public wireless communication service such as private LTE, the owner of building 1, etc., as the entity providing this wireless communication service, will be included in the "mobile communications carrier" as used in this application.

[0036] In the above embodiment, the riser unit 3 is installed above the ground floor, but the riser unit 3 and communication equipment such as the antenna 4 may be installed on the basement floor. In this case, wireless communication services using communication equipment such as the coaxial cable 3A can be realized even on the basement floor.

[0037] In the above embodiment, for example, as shown in Fig. 1, only one antenna 4 is illustrated on each floor of the building 1, but an appropriate number of antennas 4 can be arranged on each floor depending on the corresponding wireless frequency band and the radiation characteristics of the antenna. Furthermore, the antenna 4 is not limited to being used in a state in which it is properly fixed inside and outside the ceiling panel during the construction of the building 1, and may be used in a temporary state, for example, suspended by a coaxial cable 3A from a light steel frame or the like that constitutes the ceiling base material. Furthermore, the antenna 4 can be appropriately increased depending on layout changes on each floor.

[0038] In addition, during the construction of the building 1, power is supplied from the construction power source to devices that require power, such as the coaxial converter 3D, the carrier radio 7A, and the optical converter 7B. Examples of temporary construction power sources include temporary electric wires connected to the power grid of an electric power company and generators installed at the construction site. In these construction power sources, temporary voltage drops and power outages due to the operation of overcurrent relays are likely to occur when the electric wires are exposed to rainwater or when construction machinery is started. For this reason, when power is supplied to the coaxial converter 3D, the carrier radio 7A, and the optical converter 7B from the construction power source, it is preferable to provide a power stabilizing means such as an uninterruptible power supply in addition, from the viewpoint of ensuring the security of the communication equipment and the quality of communication. In addition, the possibility of failure due to leakage or the like increases when communication devices such as the antenna 4, the coaxial converter 3D, the carrier radio 7A, and the optical converter 7B are exposed to rainwater, so it is preferable to store them in a rainproof box or protective vinyl and keep them protected at least until the exterior walls and roof of the building 1 are completed.

[0039] Furthermore, the above-described embodiment and modified examples may be modified as appropriate within the scope that does not change the gist of the invention disclosed in this application.

[0040] An example of a communication system in which the equipment installed in the building 1 is configured as a system premised on the use of wireless communication services will be described below. Fig. 5 is a diagram showing an example of a communication system relating to the equipment installed in the building 1.

[0041] In recent years, communication technology has made remarkable progress, and systems that adopt various communication technologies have been put into practical use in both the consumer and industrial fields. Among these technologies, cloud computing (hereinafter referred to as "cloud") and wireless communication network technology, which allow systems to be constructed using services provided by cloud service providers, have been rapidly developed in recent years. In this embodiment, wireless communication services provided by mobile communication service providers can be used in building 1 not only after the completion of building 1, but also during construction and during test operation of air conditioning equipment before completion, so that such cloud and wireless communication network technology can be introduced as a central monitoring system for building 1.

[0042] Conventional central monitoring systems were installed in the monitoring room of the building, and only the building's facility operation and management personnel monitored and operated the operation status of the facilities using an on-premise system (hereafter referred to as "on-premise"). However, with the use of cloud and wireless communication network technology, it has become possible to view the facilities from a remote location from a viewpoint other than operation management, and the roles of operation management, energy management, etc. This allows for the optimization of the distribution system. In recent years, more advanced energy analysis has been required for the purpose of energy conservation and improving intellectual productivity, making it necessary to collect more measurement data than ever before. In light of this situation, it is extremely useful to be able to view information from the central monitoring system not only on-premise.

[0043] Therefore, a system configuration for monitoring the facilities of Building 1 can be considered, for example, as a system configuration that includes the cloud portion surrounded by the circled number "1" in Figure 5 and the wireless configuration portion surrounded by the circled number "2" in Figure 5. By adopting the cloud for the central monitoring system, there are benefits to be gained in running costs, such as minimizing the maintenance and repair of on-premises system equipment assets, making it possible to upgrade and update software assets on the cloud, and leveling out maintenance service costs. In addition, when introducing it to a building, it is possible to reduce initial costs and shorten construction time by minimizing the system equipment installed on-premises and reducing engineering work for the on-premises system. In this way, the system is characterized by the fact that it can be adopted by both the owner of Building 1 and the facility engineering company.

[0044] When adopting such a system configuration, a large amount of data transmission is required via the Internet line. Therefore, the problem of communication capacity can be solved by utilizing 5G, a new communication standard that has been gaining popularity in recent years. In addition, when adopting such a system configuration, it is necessary to take thorough security measures on the Internet, so it is desirable to adopt a communication method in which security measures are taken into consideration in the cloud.

[0045] In such a system configuration, for example, the following three operational patterns can be assumed. (1) Monitoring with different roles both on-premise and remote When the building to be monitored is of a certain size, it is necessary to have an operation and management staff stationed on-premises at all times. Rather than having the on-premises operation and management staff perform all tasks, it is often more efficient to divide the tasks into tasks that involve checking the actual equipment, such as daily inspections and equipment operation management, and tasks such as equipment operation planning and energy management. By setting up a central monitoring system that can be monitored and operated on-premises at all times, and building a cloud monitoring system that can be monitored from remote locations, it is possible to implement the monitoring required for operations both on-premises and in remote locations. (2) Integrated remote monitoring of multiple locations When the monitored site is small or medium-sized, it is not necessarily necessary for operation and management staff to be constantly monitoring, or there are buildings where reductions are required to reduce the number of operation staff and costs. However, even in these cases, emergency response is required when an abnormality occurs in the equipment. This is why a system is built to transfer only representative abnormalities. However, for equipment content or building uses where understanding only abnormality occurrences is insufficient, a central monitoring system is built on-premises and operation and management staff are stationed, even though this is not actually necessary. In such buildings, by integrating and monitoring in real time at a remote location, on-premises work can be narrowed down to a minimum of tasks such as regular patrols. (3) Operation via mobile device Systems that allow tenants to operate facilities in buildings using their mobile devices as a service have been deployed in a variety of properties in recent years. Although it is slightly different from a cloud-based central monitoring system, it is a necessary function for tenant workers as a service that utilizes the cloud when actually implemented.

[0046] Assuming such an operational pattern, the system configuration can be thought of as consisting of six components: cloud, central monitoring server, monitoring client terminal, on-premises monitoring server, on-premises monitoring client, and mobile operation terminal.

[0047] A private cloud is used as the cloud, and the communication between the on-premise and the cloud is connected by an internal company network. In this case, a VPN network using the Internet line is used, but since it is not a public cloud environment, in order to be compatible even when 5G is adopted, it is desirable to use a system that supports communication with the cloud and IoTHub technology and JSON code (a data format used for data processing that is currently widely used by cloud operators). A central monitoring server can be placed on the cloud using a monitoring network application that supports cloud configuration. It can be built on a general-purpose cloud platform that supports IoTHub technology. The monitoring client terminal is a terminal that can display and operate the monitoring screen by accessing the cloud monitoring server using a browser. The on-premise monitoring server is placed on the on-premise side so that it can be compatible with both of the above assumed patterns (1) and (2). The on-premise monitoring client is for independently monitoring and operating on the on-premise side in the above assumed pattern (1). The mobile operation terminal allows the display of web operations of the facility equipment.

[0048] In such a system configuration, a large amount of big data will be measured. For example, if this system configuration is adopted for Building 1, more than a thousand measurement points may be planned just for the radiant temperature on the ceiling and floor in order to measure the indoor environment closely. To achieve measurement at such many measurement points, a wired system would require wiring to a large number of measurement sensors, but if wireless communication technology is used, such wiring is unnecessary.

[0049] One of the characteristics of wireless communication technology is that it has many different standards for wireless communication. Therefore, when using wireless communication technology, you need to select the appropriate standard or protocol for the communication purpose and build a wireless network. Among the wireless stations defined in the Radio Law, the following are the wireless stations and their characteristics that can be used to build systems such as central monitoring. (1) Specified low power radio station A specific low-power radio is a type of low-power radio station that does not require a license under the Radio Law. It uses a frequency of 429MHz and has a low antenna power of less than 10mW. (2) Low-power data communication system radio station The radio stations include: ·Wireless LAN (IEEE 802.11) ·Wireless Sensor Network (IEEE802.15.4) -Bluetooth (IEEE 802.15.1, Bluetooth is a registered trademark). Although the characteristics of each system are different, such as the maximum number of connections and communication speed, they all use frequencies in the 2.4 to 2.5 GHz band. The Ministry of Internal Affairs and Communications prescribes technical standards for each application for these wireless stations, and only devices that are certified to comply with these standards (radio equipment with a compliance mark) can be used.

[0050] In the system to be constructed in Building 1, for example, there will be approximately 100 measurement points for temperature / humidity / CO2 concentration / illuminance, approximately 1100 measurement points for ceiling surface temperature / floor surface radiation temperature, approximately 310 measurement points for air intake airflow, and a total of approximately 1000 measurement points related to monitoring the status of task air conditioning equipment. When all of these numerous measurement points are connected to the central monitoring system by wireless communication, for example, sensors that detect indoor temperature, humidity, CO2, and illuminance can be connected by specific low-power radio or wireless LAN, air flow sensors, radiation panels, and task desk air conditioners can be connected by a wireless sensor network, and units such as DCFCUs and other fan coil units can be connected by Bluetooth. If the system is configured in this way, communication can be performed without problems even through structures, partitions, and buildings (connected by corridors) that affect radio wave strength. In addition, if each wireless station has multiple routes secured, even if a problem occurs with some equipment, communication with normal equipment can be ensured through another route. Yes, it is possible. If some or all of these communications are replaced with 5G, it goes without saying that it will be possible to measure large amounts of big data even more easily.
