[0004] In order to obtain appropriate vibration data, it is necessary to attach the vibration sensor at an appropriate position. However, there are many types of rotating machinery, and the appropriate installation positions of the vibration sensor are different for each rotating machinery. For each installation position of the vibration sensor, the appropriate posture of the vibration sensor is also different. Therefore, it may not be easy to install the vibration sensor at an appropriate installation position of the rotating machinery in an appropriate posture.

Embodiments for Carrying Out the Invention

[0015] Hereinafter, a method for installing a vibration sensor and a vibration sensor installation system according to an embodiment of the present invention will be described with reference to the drawings.

[0016] [Vibration Sensor Installation System] FIG. 1 is a schematic diagram showing a vibration sensor installation system for a rotating machine according to an embodiment. As shown in FIG. 1, the vibration sensor installation system includes a rotating machine (pump) 1, a vibration sensor 7 attached to the rotating machine 1, and an external terminal 5 that monitors the measured values of the vibration sensor 7.

[0017] In the installation system of the vibration sensor shown in FIG. 1, the rotating machine 1 is a pump, but the type of the rotating machine 1 is arbitrary. The rotating machine 1 may be, for example, a fan, an electric motor, a compressor, or the like. The number of rotating machines 1 included in the installation system of the vibration sensor may be one, or may be two or more. That is, the installation system of the vibration sensor has at least one rotating machine 1.

[0018] The external terminal 5 is a mobile terminal device such as a smartphone, a tablet computer, and a notebook personal computer. The external terminal 5 may be, for example, an intelligent terminal device (such as a desktop computer) that is not suitable for portability. In this case, the external terminal 5 may be provided in the monitoring room of the factory where the rotating machine 1 is installed.

[0019] The installation system of the vibration sensor may have a cloud system 8 capable of transmitting and receiving data with the external terminal 5. The cloud system 8 may be constructed inside the factory where the rotating machine 1 is installed, or may be constructed outside the factory where the rotating machine 1 is installed.

[0020] The installation system of the vibration sensor includes at least one vibration sensor 7. The vibration sensor 7 measures the vibration generated during the operation of the rotating machine 1. The vibration sensor 7 is installed on the rotating machine 1. The user of the rotating machine 1 can determine the presence or absence of a defect (for example, a failure) of the rotating machine 1 based on the measured value of the vibration sensor 7. The user of the rotating machine 1 can also determine the necessity of maintenance based on the measured value of the vibration sensor 7.

[0021] The vibration sensor 7 can be connected to the external terminal 5 by wire or wirelessly. The vibration sensor 7 is capable of transmitting and receiving data including the measured value of the vibration generated in the rotating machine 1 to and from the external terminal 5. The vibration sensor 7 includes, for example, a memory (not shown) capable of storing the measured value. The vibration sensor 7 includes a communication device (not shown) for transmitting and receiving data to and from the external terminal 5.

[0022] Data transmission and reception between the vibration sensor 7 and the external terminal 5 may be performed via a repeater (not shown). The vibration sensor 7 may be configured to be able to transmit and receive data with the cloud system 8. In this case, data transmission and reception between the data of the vibration sensor 7 and the external terminal 5 is performed via the cloud system 8.

[0023] FIG. 2 is a schematic diagram showing an example of the external terminal 5. As shown in FIG. 2, the external terminal 5 is, for example, a smartphone. The external terminal 5 includes a display 10, a processing device 11, and a communication device (not shown).

[0024] The communication device transmits and receives data with external devices such as the vibration sensor 7 and the cloud system 8. The display 10 is, for example, a liquid crystal display device, an organic EL display device, etc. The display 10 has, for example, a function as a touch panel.

[0025] The processing device 11 processes information and displays it on the display 10. The processing device 11 is, for example, an arithmetic processing device such as a CPU or a GPU. The processing device 11 causes the display 10 to display sensor installation information for installing the vibration sensor 7 at an appropriate installation position in an appropriate posture. The sensor installation information includes, for example, model image data and installation position data.

[0026] The model image data represents the model of the rotating machine 1 associated with the type of the rotating machine 1 in an image. The installation position data represents the recommended installation position of the vibration sensor 7 associated with the model of the rotating machine 1 in an image.

[0027] The sensor installation information is, for example, stored in advance in a memory (not shown) of the vibration sensor 7. The sensor installation information is transmitted from the vibration sensor 7 to the external terminal 5 when the user operates the external terminal 5. The sensor installation information may be stored in advance in the external terminal 5 or may be stored in advance in the cloud system 8. When the sensor installation information is stored in the cloud system 8, the user of the rotating machine 1 operates the external terminal 5, and the sensor installation information is transmitted from the cloud system 8 to the external terminal 5.

[0028] When the user installs the vibration sensor 7 on the rotating machine 1, the user operates the external terminal 5 to display the sensor installation information on the display 10, and installs the vibration sensor 7 based on the sensor installation information. By this operation, even if the user is not familiar with the installation of the vibration sensor 7, the vibration sensor 7 can be attached to the appropriate installation position in the appropriate posture. Since the user can obtain the appropriate measured value of the vibration sensor 7, it is possible to accurately determine the presence or absence of a malfunction of the rotating machine 1, the necessity of maintenance, etc.

[0029] [Installation method of vibration sensor] An example of an installation method of a vibration sensor using the vibration sensor installation system according to the embodiment will be described.

[0030] (First step: Select the model of the rotating machine) FIG. 3 is a schematic diagram showing an example of the model image data displayed on the display 10. As shown in FIG. 3, the processing device 11 (see FIG. 2) causes the display 10 to display the model image data. In the example shown in FIG. 3, two pieces of model image data D1 and D2 corresponding to the horizontal axis pump and two pieces of model image data D3 and D4 corresponding to the vertical axis pump are displayed.

[0031] The user can select the model of the rotating machine 1 on which the vibration sensor 7 is to be installed visually while comparing the model image data displayed on the display 10 with the rotating machine 1. Therefore, it is possible to avoid the user making a mistake in selecting the model of the rotating machine 1 on which the vibration sensor 7 is to be installed. The user can select the model of the rotating machine 1 by touching the image with a finger while the model of the rotating machine 1 on which the vibration sensor 7 is to be installed is displayed on the display 10.

[0032] The model image data may include the serial number or model number of the rotating machine 1 where the vibration sensor 7 is to be installed. In that case, when the user selects the model of the rotating machine 1, the user can select the model image data based on the serial number or model number described on the tag attached to the rotating machine 1.

[0033] In this embodiment, the number of vibration sensors 7 to be installed can be selected. Specifically, the number of vibration sensors 7 to be installed is input into the window W1 displayed on the display 10. The number of vibration sensors 7 to be installed may be one, or may be two or more. That is, the installation system of the vibration sensor has at least one vibration sensor 7.

[0034] (Second step: Display installation position data) When the user selects the type of the rotating machine 1, the processing device 11 causes the display 10 to display the installation position data.

[0035] FIG. 4 is a schematic diagram showing an example of the installation position data displayed on the display 10. FIG. 4 shows the installation position data when the model image data corresponding to the horizontal axis pump is selected. As shown in FIG. 4, the installation position data is, for example, data that displays the installation positions of the vibration sensors 7 recommended by the manufacturer of the rotating machine 1 on the external image of the rotating machine 1. The installation position data represents the recommended installation positions of the vibration sensors 7 associated with the model of the rotating machine 1 in an image.

[0036] In FIG. 4, four recommended installation positions are shown. The user can select the recommended installation positions. The user may install the vibration sensors 7 at all the recommended installation positions, or may select one or more installation positions from the four recommended installation positions and install the vibration sensors 7. When the installation of the vibration sensors 7 is completed, touch the "Installation completed" button.

[0037] FIG. 5 is a schematic diagram showing an example of the installation position data displayed on the display 10. As shown in FIG. 5, the processing device 11 shows, in a video, the installation position of the vibration sensor 7 recommended by the manufacturer of the rotating machine 1. The user can attach the vibration sensor 7 to the rotating machine 1 according to FIGS. 4 and 5.

[0038] FIG. 6 is a schematic diagram showing the rotating machine 1 with the vibration sensor 7 installed and the external terminal 5. In FIG. 6, information for confirming the connection between the vibration sensor 7 and the processing device 11 is displayed on the display 10. For example, the identification information of the vibration sensor 7 is displayed on the display 10. The identification information may be, for example, the sensor name. The identification information may be information (such as a MAC address) for identifying the individual of the vibration sensor 7. By displaying the identification information of the vibration sensor 7, the user can confirm that the vibration sensor 7 and the processing device 11 are connected.

[0039] (Step 3: Acquisition of actual installation information and comparison with the installation position data) FIG. 7 is a schematic diagram showing an example of the installation position of the external terminal 5. FIG. 8 is a schematic diagram showing an example of the display 10 that displays a button for instructing the start of calculation for acquiring the actual installation information of the vibration sensor 7.

[0040] In FIG. 7, the installation position of the external terminal 5 with respect to the rotating machine 1 is displayed. The external terminal 5 is, for example, in a posture in which the long side direction is aligned with the longitudinal direction of the rotating machine 1. With the external terminal 5 installed at the positions shown in FIGS. 7 and 8, the processing device 11 acquires the actual installation information of the vibration sensor 7 by wireless communication with the vibration sensor 7. The wireless communication is, for example, BLE communication (BLE: Bluetooth (registered trademark) Low Energy), etc.

[0041] The vibration sensor 7 preferably includes at least one of a geomagnetic sensor and an acceleration sensor. The geomagnetic sensor detects the geomagnetism in the vibration sensor 7 and outputs a detection signal. When using a geomagnetic sensor, it is also desirable for the external terminal 5 to be equipped with a geomagnetic sensor. The processing device 11 can detect the installation posture of the vibration sensor 7 based on, for example, the detection signal from the geomagnetic sensor provided in the vibration sensor 7 and the detection signal from the geomagnetic sensor provided in the external terminal 5.

[0042] The acceleration sensor detects the gravitational acceleration in the vibration sensor 7 and outputs a detection signal. The processing device 11 can detect the installation posture of the vibration sensor 7 based on the detection signal from the acceleration sensor.

[0043] The processing device 11 can also detect the radio wave intensity in wireless communication (for example, the radio wave intensity of BLE communication). The processing device 11 can measure the distance to the vibration sensor 7 based on the detected value of the radio wave intensity. Therefore, the processing device 11 can obtain information regarding the installation position of the vibration sensor 7.

[0044] As shown in FIG. 8, when an instruction to start the calculation is given, the processing device 11 can obtain the actual installation information (for example, installation posture, installation position) of the vibration sensor 7 based on the detected values of the geomagnetic sensor, acceleration sensor, radio wave intensity, etc.

[0045] FIG. 9 is a schematic diagram showing an example of a selection screen for the vibration sensor 7. As shown in FIG. 9, the target vibration sensor 7 can be selected. FIG. 10 is a schematic diagram showing an example of the display 10 on which the actual installation information of the vibration sensor 7 is displayed. FIG. 10 shows the result of comparing the actual installation information and the installation position data for each vibration sensor 7.

[0046] In the example shown in FIG. 10, for the first vibration sensor 7 (sensor 1), since the actual installation information (e.g., installation attitude, installation position) of this vibration sensor 7 does not match the installation position data, it is instructed that a correction of 20° clockwise should be applied to the orientation of the vibration sensor 7. "20° clockwise" represents the difference between the actual installation information and the installation position data. In the example shown in FIG. 10, by showing this difference, the actual installation information about the first vibration sensor 7 is displayed. In this way, when the actual installation information of the vibration sensor 7 is not appropriate, the difference between the actual installation information and the installation position data can be displayed on the display 10. The user corrects the installation information of the first vibration sensor 7 (sensor 1) according to this instruction. For example, the user corrects the orientation of the vibration sensor 7 by 20° clockwise. Thereby, the actual installation information of the vibration sensor 7 can be made to match the installation position data.

[0047] The actual installation information of the vibration sensor 7 is not limited to the orientation (installation attitude) of the vibration sensor 7, and may also be the installation position of the vibration sensor 7. In this case, the difference between the actual installation information of the vibration sensor 7 and the installation position data can be displayed as a distance. For example, assuming that the rotational axis direction of the rotating machine 1 is the X-axis direction, the difference between the actual installation information of the vibration sensor 7 and the installation position data can be displayed as "2 mm in the X-axis direction". In the case of this example, the user can make the actual installation information of the vibration sensor 7 match the installation position data by shifting the position of the vibration sensor 7 by 2 mm in the X-axis direction.

[0048] In the example shown in FIG. 10, for the second vibration sensor 7 (sensor 2), "OK" is displayed. This means that for the second vibration sensor 7 (sensor 2), since the actual installation information and the installation position data match, there is no need to apply a correction to the installation information. That is, for the second vibration sensor 7 (sensor 2), it is shown on the display 10 that the installation information is appropriate. In the example shown in FIG. 10, the actual installation information about the second vibration sensor 7 is displayed by a display indicating that the installation information is appropriate.

[0049] In FIG. 10, for the second vibration sensor 7 (sensor 2), a completion button for the user to approve the installation information is displayed on the display 10. The user can approve this installation information by pressing the completion button.

[0050] FIG. 11 is a schematic diagram showing an example of the display 10 after the installation information (for example, installation posture, installation position) of the first vibration sensor 7 (sensor 1) has been modified. In FIG. 11, for the first vibration sensor 7 (sensor 1), a registration button for the user to approve the installation information is displayed on the display 10. The user can approve this installation information by touching the registration button.

[0051] By the user performing these operations for all the vibration sensors 7, all the vibration sensors 7 can be attached at appropriate installation positions in appropriate postures. FIG. 12 is a schematic diagram showing an example of the display 10 after the installation information has been approved for all the vibration sensors 7.

[0052] FIG. 13 is a flowchart showing an example of the installation method of the vibration sensor 7. As shown in FIG. 13, the processing device 11 (see FIG. 2) causes the display 10 to display the model image data (see FIG. 3). The user selects the model of the rotating machine 1 to which the vibration sensor 7 is to be installed (STEP1). At this time, the user can select the number of vibration sensors 7 to be installed.

[0053] The processing device 11 causes the display 10 to display the installation position data. The user installs the vibration sensor 7 on the rotating machine 1 according to the installation position data (STEP2) (see FIG. 4).

[0054] The processing device 11 acquires the actual installation information of the vibration sensor 7 through wireless communication with the vibration sensor 7 (STEP3) (see FIGS. 10 and 11). The processing device 11 determines whether the actual installation information of the vibration sensor 7 matches the installation position data (STEP4). When the actual installation information of the vibration sensor 7 matches the installation position data, it can be determined that the actual installation information of the vibration sensor 7 is appropriate, and thus the vibration sensor 7 in this installation form is registered (STEP5) (see FIGS. 10 and 11).

[0055] When the actual installation information of the vibration sensor 7 does not match the installation position data, it can be determined that the actual installation information of the vibration sensor 7 is not appropriate, and thus corrections are made to the installation information of the vibration sensor 7 (such as the installation posture and installation position) (STEP6). When the actual installation information of the vibration sensor 7 matches the installation position data, the vibration sensor 7 in this installation form is registered (STEP5) (see FIGS. 10 and 11).

[0056] [Effects of the Vibration Sensor Installation System and Installation Method of the Embodiment] In the vibration sensor installation system of this embodiment, the processing device 11 causes the display 10 to display the actual installation information of the vibration sensor 7. Therefore, when the installation information of the vibration sensor 7 (such as the installation posture and installation position) does not match the installation position data, the installation information of the vibration sensor 7 can be corrected. Thus, the vibration sensor 7 can be attached to the rotating machine 1 at an appropriate installation position and in an appropriate posture. Therefore, accurate vibration data can be acquired by the vibration sensor 7.

[0057] The vibration sensor installation system of this embodiment can clearly present whether the actual installation information of the vibration sensor 7 is appropriate, so that the user can easily correct the installation posture, installation position, etc. of the vibration sensor 7.

[0058] The vibration sensor installation system of this embodiment can attach a plurality of vibration sensors 7 to the rotating machine 1 at appropriate installation positions and in appropriate postures through a series of operations. Therefore, a plurality of vibration sensors 7 can be appropriately attached to the rotating machine 1 with easy operation.

[0059] If the actual installation information of the vibration sensor 7 is appropriate, the processing device 11 can present the user's operation in an easy-to-understand manner by causing the display 10 to display a button for the user to approve this installation information.

[0060] If the actual installation information of the vibration sensor 7 is not appropriate, the processing device 11 can cause the display 10 to display the difference between the actual installation information (for example, installation posture, installation position) and the installation position data. As a result, the user can appropriately correct the installation information of the vibration sensor 7.

[0061] The processing device 11 can present the user's operation in an easy-to-understand manner by causing the display 10 to display the model image data and the installation position data so that the user can select them.

[0062] In the method for installing the vibration sensor according to the present embodiment, the processing device 11 causes the display 10 to display the actual installation information of the vibration sensor 7. Therefore, if the installation information of the vibration sensor 7 (for example, installation posture, installation position) does not match the installation position data, the installation information of the vibration sensor 7 can be corrected. Accordingly, the vibration sensor 7 can be attached to the rotating machine 1 in an appropriate posture at an appropriate installation position. Thus, accurate vibration data can be acquired by the vibration sensor 7.

[0063] The above-described embodiment is described for the purpose of enabling a person having ordinary knowledge in the technical field to which the present invention pertains to implement the present invention. Various modifications of the above embodiment can be naturally made by those skilled in the art, and the technical idea of the present invention can also be applied to other embodiments. Therefore, the present invention is not limited to the described embodiment, but is interpreted in the broadest scope in accordance with the technical idea defined by the claims. For example, the communication between the processing device for acquiring the actual installation information of the vibration sensor and the vibration sensor is not particularly limited as long as it is wireless communication. The communication between the processing device and the vibration sensor may be, for example, Wifi communication.
