Referring to FIG. 1, a smart jet fan 100 using an IoT/ICT according to an embodiment of the present invention includes an axial fan 110, a sensor module 120, and a wireless transmitter 130.

Here, the smart jet fan 100 using IoT/ICT may be a blower for a road tunnel installed in the ceiling 1 in the tunnel 1, as shown in FIG. 2. However, the present invention is not limited thereto, and the smart jet fan 100 using IoT/ICT may include a blower for a subway, an industrial centrifugal blower, an industrial pump, and an industrial compressor.

At this time, the smart jet fan 100 using IoT/ICT may be controlled and operated by an external maintenance integrated system using the Internet of Things (IoT) and Information Communication Technology (ICT).

The axial fan 110 may include a motor 112, a fan 114, and a housing 116. Here, the fan 114 is rotated according to the driving of the motor 112, the motor 112 and the fan 114 may be accommodated in the interior of the housing 116.

5, the motor 112 may be a fan 114 is connected to the rotation axis of the rotor (112c). At this time, the motor 112 may include a load-side bearing 112a on the side to which the fan 114 is connected and a half-load side bearing 112a on the opposite side.

The sensor module 120 controls the temperature of the load-side bearing 112a of the motor 112, the vibration state for the vertical, horizontal and axial directions of the axial fan 110, and the tilting state for the three axes of the axial fan 110. Can be measured.

Here, the sensor module 120 may include a temperature sensor 122, a three-axis vibration sensor 124 and a gyro sensor 126. At this time, the temperature sensor 122 may measure the temperature of the load-side bearing 112a in order to detect the state of the lubricant because the temperature may increase depending on the state of the lubricant of the load-side bearing 112a.

In addition, the three-axis vibration sensor 124 is an acceleration sensor in three directions such as vertical (Z-axis), horizontal (Y-axis), and axial (X-axis) of the axial fan 110 by rotation of the fan 114. The vibration state of the axial fan 110 can be measured. Here, the vibration state may be a vibration state of the load-side bearing 112a.

In addition, the gyro sensor 126 may measure the tilting state of the X-axis, Y-axis, and Z-axis of the axial fan 110 with respect to three axes. That is, the gyro sensor 126 can measure the installation deformation such as the degree of inclination with respect to the state in which the axial fan 110 is installed on the ceiling of the tunnel 1. At this time, the gyro sensor 126 may measure rolling, pitching, and yawing angles, which are rotation angles for each of the X-axis, Y-axis, and Z-axis.

As such, the sensor module 120 may measure information on a total of 7 points, such as 1 point of temperature, 3 points of vibration, and 3 points of installation deformation.

4 and 5, the sensor module 120 may be integrally formed with a temperature sensor 122, a three-axis vibration sensor 124, and a gyro sensor 126. That is, the sensor module 120 may be integrally formed with three types of sensors in one housing.

Here, since the sensor module 120 is integrally formed with the temperature sensor 122, the 3-axis vibration sensor 124, and the gyro sensor 126, the sensor module 120 should be installed at a position capable of measuring both temperature, vibration, and installation deformation. do.

To this end, the sensor module 120 may be installed near the load side bearing 112a of the motor 112. That is, the sensor module 120 can measure the bearing temperature of the motor 112 and at the same time, the load side bearing 112a, which is the side to which the fan 114 is connected, so as to measure vibration and installation deformation by the fan 114. Can be installed in the vicinity.

Accordingly, it is possible to measure temperature, vibration, and installation deformation at the same time without having to install a plurality of sensors for each position of the axial fan 110, and at the same time, it is possible to solve the complexity of management and wiring by using a plurality of sensors.

The wireless transmitter 130 may be installed on one side of the outer periphery of the housing 116. Referring to FIG. 3, the wireless transmitter 130 may be installed in a large central portion around the outer periphery of the housing 116, but is not particularly limited.

At this time, the wireless transmitter 130 may be wiredly connected to the sensor module 120 to wirelessly transmit data measured by the sensor module 120 to an external management server through a repeater. Here, the wireless transmitter 130 may transmit measurement data to a repeater in a short-range communication method. As an example, short-range communication may include LoRa, Zigbee and WiFi.

Meanwhile, the smart jet fan 100 using the IoT/ICT according to the embodiment of the present invention may further include a black box 140 and a power supply unit 150.

The black box 140 is used to search for vehicles that are applied when a crash accident occurs in the smart jet fan 100 using IoT/ICT due to a collision caused by an excessive vehicle.

To this end, the black box 140 may be installed at one end of the housing 116. Referring to FIG. 3, the black box 140 may be installed in front of the housing 116, that is, in the road tunnel 1 in which the axial fan 110 is installed, so that the vehicle can monitor the traveling direction. At this time, the black box 140 may be installed on the upper side from one end of the housing 116.

Also, the black box 140 may include a camera for photographing a surrounding situation and a storage unit for storing the captured image. At this time, the black box 140 may transmit the stored image to the management server 300 through the wireless transmitter 130.

The power supply unit 150 may be installed on one side of the outer periphery of the housing 116. Referring to FIG. 3, the power supply unit 150 may be installed at a central portion around the outer periphery of the housing 116. That is, the power supply unit 150 may be installed near the wireless transmitter 130.

The power supply unit 150 may receive external power and convert and supply power to dedicated power for the axial fan 110, the sensor module 120, and the wireless transmitter 130, respectively.

For example, the power supply unit 150 may receive a 3-phase 380V AC power and transform it into a single-phase 220V AC power to provide the axial flow fan 110. In addition, the power supply unit 150 may convert 220V AC power to 3.3V DC and 24V DC to supply to the sensor module 120 and the wireless transmitter 130, respectively.

Accordingly, without supplying separate power for the sensor module 120, the wireless transmitter 130, and the black box 140, power can be automatically supplied using the power of the axial fan 110.

At this time, the wireless transmitter 130 may transmit data to the repeater in a certain data format. 6 is a diagram illustrating a data format transmitted from the wireless transmitter of FIG. 5, and FIG. 7 is a diagram showing the configuration of an ID in FIG.

The wireless transmitter 130 can efficiently transmit measurement data without loss through IoT Message Queuing Telemetry Transport (MQTT) protocol. At this time, the wireless transmitter 130 may generate data including ID, temperature measurement data, vibration state measurement data, and installation deformation measurement data, as illustrated in FIG. 6, and transmit the generated data.

At this time, the measurement data for the vibration state may include measurement data for the horizontal (H), vertical (V), and axis (A) directions. In addition, the measurement data for the installation deformation may include measurement data of the X-axis (rolling), Y-axis (pitch), and Z-axis (yaw).

Here, the ID may be identification information corresponding to the smart jet fan 100 using the corresponding IoT/ICT. At this time, the ID can be coded for comprehensive management by region. Referring to FIG. 7, the ID may include an area, a road, a tunnel, and a smart jet fan number (#).

By this, it is possible to easily perform additional expansion of the sensor module 120 for each region, road, tunnel, and fan, and at the same time, it is possible to easily identify the installation location of the sensor module 120 only with ID information.

At this time, the wireless transmitter 130 may wirelessly transmit the identification information (ID) and measurement data at predetermined time intervals. For example, the wireless transmitter 130 may transmit measurement data in real time, but is not limited thereto, and may transmit measurement data at predetermined time intervals such as hourly, daily, weekly, and monthly.

Here, the wireless transmitter 130 may store the data measured by the sensor module 120 for a certain period of time, and periodically transmit the data to the management server through the repeater. At this time, the wireless transmitter 130 may sequentially transmit and delete previously stored data, and store new measurement data.

Hereinafter, a smart jet fan maintenance integrated system using IoT/ICT according to an embodiment of the present invention will be described in more detail with reference to FIGS. 8 to 11. 8 is a block diagram showing a smart jet fan maintenance integrated system using IoT/ICT according to an embodiment of the present invention.

Here, the smart jet fan maintenance integrated system 10 using IoT/ICT can integrally maintain and manage the smart jet fan 100 using IoT and ICT.

The smart jet fan maintenance integrated system 10 using IoT/ICT may include a smart jet fan 100 using IoT/ICT, a repeater 200, and a management server 300.

The integrated system for smart jet fan maintenance using the IoT/ICT 10 may be linked with the tunnel controller 400. Here, the tunnel controller 400 is for controlling facilities in the tunnel 1 and can control power on/off and driving of the axial fan 110.

The smart jet fan 100 using IoT/ICT may include an axial fan 110, a sensor module 120, and a wireless transmitter 130, as illustrated in FIGS. 1 to 8. Optionally, the smart jet fan 100 using IoT/ICT may further include a black box 140. Here, since the smart jet fan 100 using IoT/ICT is the same as described above, a detailed description will be omitted.

The repeater 200 may perform short-range wireless communication with the smart jet fan 100 using IoT/ICT. Here, the repeater 200 may perform short-range wireless communication in any one of LoRa, Zigbee and WiFi.

The management server 300 may receive measurement data of the smart jet fan 100 using IoT/ICT from the repeater 200 through a wired or wireless communication network. At this time, the management server 300 may receive measurement data from the repeater 200 in a wired manner such as Ethernet or a wireless method using any one of 3G, 4G, and 5G wireless public communication networks.

In addition, the management server 300 may store and manage the received measurement data, and perform maintenance such as determining an abnormal state of the axial flow fan 110, an abnormal state alarm, and the like based on the measured data.

Accordingly, the status of the smart jet fan 100 using the IoT/ICT distributedly distributed by region, road, and tunnel can be collectively monitored by the remote management server 300. Therefore, it is possible to easily and effectively perform maintenance of the smart jet fan 100 using IoT/ICT, while reducing the management cost.

In addition, the management server 300 may be interlocked with the mobile device 300' for an administrator through a management maintenance app. That is, the manager mobile device 300' may monitor and maintain measurement data for the smart jet fan 100 using the IoT/ICT being managed by the management server 300. Here, the mobile device 300' includes a smart phone, a PDA, and a tablet PC, but is not limited thereto, and may be a device capable of carrying and communicating.

At this time, the smart jet fan maintenance integrated system 10 using IoT/ICT depends on the length of the tunnel 1, and the smart jet fan 100, repeater 200 and management server 300 using IoT/ICT are various. It can be installed in the form.

9 is a schematic diagram showing an example of the installation state of the smart jet fan, repeater and management server using IoT/ICT in FIG. 8, and FIG. 10 is a smart jet fan, repeater and management server using IoT/ICT in FIG. It is a schematic diagram showing another example of the installation state.

Referring to FIG. 9, when the length of the tunnel 1 is greater than a range in which communication between the smart jet fan 100 and the repeater 200 using IoT/ICT is possible, the repeater 200 is approximately the length of the tunnel 1 It can be installed centrally.

For example, when the length of the tunnel 1 is approximately twice the communication distance D of the visible distance LOS, the repeater 200 may be installed at the center of the tunnel 1. Therefore, the distance between the repeater 200 and the smart jet fan (#1 to #4) installed in one section and the smart jet fan (#N-3 to #N) installed in the section of the other side is a communication distance (D ), it is possible to transmit measurement data to the repeater 200 by short-range wireless communication.

At this time, the repeater 200 may transmit measurement data to the management server 300 in a wired or wireless communication method. Alternatively, the repeater 200 may transmit measurement data to the manager's mobile device 300'.

Referring to FIG. 10, when the length of the tunnel 1 is much larger than a communication range between the smart jet fan 100 and the repeater 200 using IoT/ICT, the repeater 200 may be provided in a plurality of tunnels 1 Can be installed as a dog.

In one example, when the length of the tunnel 1 is approximately 4 times the communication distance D, the repeater 200 may be installed at points 1/4 and 3/4 of the length of the tunnel 1. Therefore, since the distance from the repeater 200 installed at the quarter point of the smart jet fan (#1 to #4) installed on one side is within the communication distance D, measurement data can be transmitted by short-range wireless communication. .

Similarly, the smart jet fan (#N-3 to #N) installed in the other section is measured by short-range wireless communication since the distance from the repeater 200 installed at the 3/4 point is within the communication possible distance (D). Data may be transmitted to the repeater 200.

At this time, the plurality of repeaters 200 may transmit measurement data to the management server 300 by wired or wireless communication, respectively. Alternatively, the repeater 200 may transmit measurement data to the manager's mobile device 300'.

FIG. 11 is a detailed block diagram of the management server in FIG. 8.

The management server 300 may include a communication unit 310, a control unit 320, an alarm unit 330, and a database 340.

The communication unit 310 may perform wired/wireless communication with the repeater 200. Here, the communication unit 310 may perform communication using a wired method such as Ethernet or a wireless method using any one of 3G, 4G and 5G wireless public communication networks.

The controller 320 determines the abnormal state of the smart jet fan 100 using the IoT/ICT based on the measurement data received through the repeater 200, and the abnormal state of the smart jet fan 100 using the IoT/ICT Let's analyze the trend. The control unit 320 may include an abnormality determination unit 322 and a trend analysis unit 324.

The abnormality determination unit 322 determines whether or not the measurement data received through the repeater 200 exceeds the first threshold value, and when the first threshold value is exceeded, the smart jet fan 100 using IoT/ICT ). Here, the first threshold value is a pre-fixing step of the smart jet fan 100 using IoT/ICT, but may continue to operate for a short period of time, but corresponds to an alert step requiring attention.

In one example, the first threshold value may be 80°C for the bearing temperature, 7 mm/s for the bearing vibration, and 5° for the deformation angle. Here, when the bearing temperature exceeds 80°C, it can be predicted that the possibility of a future failure is high due to a temperature rise due to insufficient lubricant of the motor 112. In addition, when the bearing vibration exceeds 7 ㎜/s, the dynamic imbalance condition increases when rotating due to contamination or damage of the impeller surface, and vibration increases or the turnbuckle breaks, resulting in a smart jet fan using IoT/ICT (100) It can be predicted that the binding state of is incomplete or the fan 114 is likely to be damaged. In addition, when the deflection angle is 5° or more, the load is biased to one side as the smart jet fan 100 using the IoT/ICT is tilted to one side, and a fall of the smart jet fan 100 using the IoT/ICT may occur later. It can be predicted that the likelihood is high.

However, the first threshold value is not limited to this, and may be set in advance according to the characteristics of the smart jet fan 100 using IoT/ICT, the installation structure of the tunnel 1 and the climate characteristics of the installation area.

At this time, the abnormality determination unit 322 may alarm the failure signs of the smart jet fan 100 using the IoT/ICT through the alarm unit 330. By doing so, it is possible to immediately detect a failure sign and establish a failure action and failure prevention maintenance plan.

In addition, the abnormality determining unit 322 determines whether the received measurement data exceeds the second threshold value, and when the second threshold value is exceeded, the smart jet fan 100 using the IoT/ICT is broken. I can judge. At this time, the second threshold value corresponds to a stage in which the danger of a heavy machinery such as rotor and bearing damage is expected to be stopped immediately if the operation continues beyond the warning level.

As an example, the second threshold may be 90°C for temperature, 11 mm/s for bearing vibration, and 10° for deformation angle. Here, when the bearing temperature exceeds 90°C, a fire may occur due to insufficient lubricant of the motor 112. In addition, when the bearing vibration exceeds 11 mm/s, the turnbuckle is broken, and the binding state of the smart jet fan 100 using IoT/ICT may be incomplete or the fan 114 may be damaged. In addition, when the deformation angle is 10° or more, since the load is biased to one side as the smart jet fan 100 using IoT/ICT is tilted to one side, the fall of the smart jet fan 100 using IoT/ICT is prevented. Can cause.

However, the second threshold value is not limited to this, and may be set in advance according to the characteristics of the smart jet fan 100 using IoT/ICT, the installation structure of the tunnel 1 and the climate characteristics of the installation area.

At this time, the abnormality determination unit 322 may be controlled to stop the smart jet fan 100 using the IoT/ICT through the tunnel controller 400. As a result, the smart jet fan 100 using the IoT/ICT having an abnormality is continuously operated to prevent additional accidents such as fire and fall of the smart jet fan 100 using the IoT/ICT.

In addition, the abnormality determining unit 322 determines the cause of the failure of the smart jet fan 100 using the IoT/ICT according to the determination of the abnormal state of the smart jet fan 100 using the IoT/ICT. Can be transferred to.

Thereby, by making the necessary preparations for the action to the manager dispatched to the site for the abnormal action of the smart jet fan 100 using IoT/ICT, it is possible to perform the fault action more quickly.

The trend analysis unit 324 may analyze an abnormal trend of the smart jet fan 100 using IoT/ICT based on the measured data. For example, the trend analysis unit 324 may statistically calculate a cause, an occurrence cycle, and an area where an abnormal state of the smart jet fan 100 using the IoT/ICT occurs.

At this time, the trend analysis unit 324 may establish a periodic preventive maintenance plan according to the abnormal trend of the smart jet fan 100 using IoT/ICT. As an example, the trend analysis unit 324 may establish a preventive maintenance schedule. Here, the trend analysis unit 324 may establish a preventive maintenance schedule according to the location of the area, road, and tunnel where the smart jet fan 100 using IoT/ICT is installed.

Thereby, it is possible to minimize the number of dispatches and the number of lanes controlled for preventive maintenance. Therefore, it is possible to reduce the time and the number of people required for preventive maintenance, and it is possible to maximize maintenance efficiency by performing maintenance systematically and easily and effectively.

Also, the trend analysis unit 324 may establish a preliminary plan for preventive maintenance such as parts required for preventive maintenance. Thereby, preventive maintenance can be carried out smoothly after dispatching, thereby minimizing road congestion due to road control.

The alarm unit 330 may alarm the abnormal state of the smart jet fan 100 using the IoT/ICT by the control unit 320. Here, the alarm unit 330 may visually alarm on a monitor (not shown) or audible alarm through sound means (not shown).

At this time, the alarm unit 330 displays the area where the smart jet fan 100 using the IoT/ICT in an abnormal state is installed on the map, or the tunnel in which the smart jet fan 100 using the IoT/ICT in an abnormal state is installed ( 1) The position within can be displayed.

The database 340 may store measurement data received through the repeater 200 for each smart jet fan 100 using IoT/ICT.

At this time, the database 340 may include identification information 342 of the smart jet fan 100 using IoT/ICT. Here, the identification information 342 may include an area, a road, a tunnel, and an axial fan number (#).

In addition, the database 340 may include measurement data 344 received for the smart jet fan 100 using the corresponding IoT/ICT. Here, the measurement data includes the temperature of the motor 112 bearing, the vibration state for the horizontal (H), vertical (V), and axis (A) directions, the X-axis (rolling), Y-axis (pitch), and Z-axis ( Yawing).

In addition, the database 340 may include an abnormal state setting condition 346 for determining an abnormal state for the smart jet fan 100 using IoT/ICT. Here, the condition setting condition 346 may be a first threshold value and a second threshold value for determining the abnormal condition by the control unit 320.

With this configuration, the present invention can simultaneously measure temperature, vibration, and installation deformation even with a single housing.

In addition, the present invention can be collectively monitored at a remote location, thereby reducing maintenance costs by easily and effectively performing maintenance.

In addition, the present invention can take prompt action in the event of a failure indication, and can prevent additional accidents due to the failure.

In addition, according to the present invention, it is possible to establish a preventive maintenance plan by predicting a failure, so that maintenance of a smart jet fan using IoT/ICT can be systematically performed, thereby maximizing maintenance efficiency.
