However, the present invention is not limited to this, and the wireless communication unit 150 may wirelessly receive data (e.g., operation presence / absence data) transmitted from a central center (not shown).

The wireless communication unit 150 may be implemented using a local wireless communication scheme (e.g., Bluetooth, NFC, WiFi) or a remote wireless communication scheme (e.g., LTE, 3G, 4G, or 5G).

Therefore, the operation monitoring apparatus of the rotating machine according to the present embodiment is formed in a detachable form as shown in FIG. The battery may include a replaceable battery or a rechargeable battery.

FIG. 2 is an exemplary diagram for explaining a schematic configuration of an operation and monitoring apparatus for a rotating machine according to an embodiment of the present invention. Referring to FIG.

The controller 140 determines whether the device is operating using the stored data.

FIG. 3 is an exemplary diagram for explaining a method of determining whether or not an apparatus operates in FIG. 1; FIG.

As shown in FIG. 3, the control unit 140 detects (or learns) vibration information generated in a device (i.e., various equipments or devices including a rotating device) (S101).

At this time, various types of vibration patterns arise in various devices in the field. Therefore, it can be seen that the same vibration pattern occurs within the error range in the same type of apparatus. That is, the operation monitoring apparatus of the rotating device according to the present embodiment can detect the vibration pattern information generated according to the type of device to be operated or not, and store the detected vibration pattern information in an internal memory (not shown).

The control unit 140 also collects sensing data (e.g., temperature, current, etc.) detected by the device (i.e., various facilities or devices including a rotating device) (S102).

As described above, various devices are installed in the field, and at least one of the same devices is installed. Therefore, in the same type of device, the same sensing data is generated within the error range. That is, the operation monitoring apparatus of the rotating device according to the present embodiment can detect the sensing data generated according to the type of device to be operated or not, and store the sensed data in an internal memory (not shown).

Further, the control unit 140 determines the correlation (i.e., the correlation between the vibration information set for determining whether there is an operation or not and the reference value for sensor information with respect to each device) of the detected vibration information and the sensor information (S103) whether or not the corresponding device (that is, various equipments or devices including rotating devices) operates.

The controller 140 outputs the operation state of the device (i.e., various equipments or devices including the rotating device) through the output unit 160 (S104).

That is, the control unit 140 outputs the operation state of the device (i.e., various equipments or devices including the rotary device) that determines the presence or absence of the operation using a combination of characters, images, lights, or sounds.

4 is an exemplary diagram for explaining a method of setting a reference value for determining whether or not an apparatus operates by using the correlation of vibration information in FIG.

4, the control unit 140 confirms the vibration values (# 1_value, # 2_value, # 3_value) of the same kind of devices installed in the field (i.e., equipments of the same type) (S201, S202 , S203).

At this time, since the vibration values are vibration information detected by the same device, the similarity of the correlation can be confirmed (S301). That is, the vibration values (# 1_value, # 2_value, # 3_value) detected in the same type of devices have a similar vibration pattern within the error range.

Therefore, the controller 140 detects a minimum value (e.g., a minimum amplitude value) of the detected vibration values (# 1_value, # 2_value, # 3_value) (S302) and sets it as a reference value for determining whether there is an operation (S303) .

In another embodiment, a range of the minimum value and the maximum value (e.g., maximum amplitude value) of the detected vibration values (# 1_value, # 2_value, # 3_value) may be set as a reference value, and the detected vibration values # 1_value, # 2_value, # 3_value) (for example, an average amplitude value) may be set as a reference value. That is, in setting the reference value, the reference value can be set in a manner that can determine whether there is a more accurate operation, without being limited to a specific method.

As described above, according to the present embodiment, the operation data of the rotary device can be immediately checked even during the field inspection, and it is possible to attach / detach the device for monitoring the operation easily on the field while the user is carrying. The operation data can be checked to diagnose the condition, and data can be transmitted through the wireless communication module, thereby improving the scalability and safety, thereby reducing the risk of accident to the on-site user.
