[0036] Figure 2 Schematic diagrams showing some embodiments of the vibration sensor of the present disclosure.
[0037] like Figure 1 and Figure 2 As shown, the vibration sensor 10 includes a vibration detection device 11 and a magnetic component 12 .
[0038] The vibration detection device 11 is configured to detect vibration information of the device under test.
[0039] The magnetic component 12 is configured to be detachably connected to the device under test by using magnetism, wherein a first surface of the magnetic component 12 is rigidly connected to the vibration detection device 11 .
[0040] In some embodiments, the rigid connection may be, for example, a mortise and tenon joint, a glue joint, a weld, a riveted joint, or a screw joint.
[0041] The magnetic component is detachably connected to the device under test by utilizing magnetism, so that the vibration sensor can be flexibly installed and the installation position can be flexibly adjusted.
[0042] The first surface of the magnetic component is rigidly connected to the vibration detection device, so that neither relative movement nor relative rotation occurs between the magnetic component and the vibration detection device, thereby ensuring the accuracy of vibration information of the device under test detected by the vibration detection device.
[0043] In some embodiments, the magnetic component 12 may be, for example, a magnetic iron sheet.
[0044] In the above embodiment, the vibration information of the device under test is detected by the vibration detection device in the vibration sensor, and the detachable connection between the vibration sensor and the device under test is realized by the magnetic component in the vibration sensor. The first surface of the magnetic component is rigidly connected to the vibration detection device, thereby ensuring the non-displacement connection between the vibration detection device and the magnetic component, and ensuring the accuracy of the vibration information detected by the vibration detection device. The magnetic component utilizes magnetism to realize the detachable connection between the vibration sensor and the device under test, thereby realizing a vibration sensor that can be flexibly installed.

[0046] Figure 4 Schematic diagrams showing other embodiments of the vibration sensor of the present disclosure.
[0047] like Figure 3 and Figure 4 As shown, in Figure 1 and Figure 2 Based on the vibration sensor 10 shown, the vibration sensor 10 further includes an anti-slip layer 31 .
[0048] The anti-slip layer 31 is adhered to the second surface of the magnetic component 12 , wherein the first surface is different from the second surface.
[0049] In some embodiments, the anti-slip layer 31 is configured to increase the friction between the vibration sensor and the device under test.
[0050] By adhering the anti-slip layer to the second side of the magnetic component, the risk of inaccurate vibration information detection due to displacement between the vibration sensor and the device under test is reduced.
[0051] In some embodiments, the first surface is in opposing relation to the second surface.
[0052] If the magnetic component 12 is a magnetic iron sheet, the first surface of the magnetic component and the second surface of the magnetic component are in an opposing relationship.
[0053] In the above embodiment, the vibration information of the device under test is detected by the vibration detection device in the vibration sensor, and the detachable connection between the vibration sensor and the device under test is realized by the magnetic component in the vibration sensor. The first surface of the magnetic component is rigidly connected to the vibration detection device, thereby ensuring the non-displacement connection between the vibration detection device and the magnetic component, and ensuring the accuracy of the vibration information detected by the vibration detection device. The magnetic component utilizes magnetism to realize the detachable connection between the vibration sensor and the device under test, thereby realizing a vibration sensor that can be flexibly installed.
[0054] Figure 5Schematic diagrams showing some embodiments of the industrial unit vibration monitoring device disclosed herein.
[0055] like Figure 5 As shown, the industrial unit vibration monitoring device includes the vibration sensor 10, the wireless node 51, the gateway 52 and the comparator 53 in any one of the above embodiments.
[0056] In some embodiments, the vibration sensor 10 is configured to be mounted on a motor bearing in an industrial machine.
[0057] By installing the vibration sensor on the motor bearing of the industrial machine set, the vibration information of the device under test can be detected more accurately. The device under test can be, for example, a motor in the industrial machine set.
[0058] The wireless node 51 is configured to be communicatively connected with the vibration sensor.
[0059] In some embodiments, the wireless node 51 is further configured to receive vibration information detected by the vibration sensor 10 and forward the vibration information to the gateway 52 .
[0060] The communication between the vibration sensor and the gateway is realized through the wireless node, so that the vibration sensor can transmit the vibration information to the gateway.
[0061] In some embodiments, the wireless node 51 is configured to be installed in an area within a threshold distance range from the vibration sensor.
[0062] The wireless node is installed near the vibration sensor so that the wireless node can receive the vibration information of the vibration sensor.
[0063] In some embodiments, the wireless node 51 interacts and communicates with the gateway 52 via a wireless network.
[0064] The gateway 52 is configured to communicate with the wireless nodes.
[0065] In some embodiments, the gateway 52 is further configured to receive vibration information and forward the vibration information to the comparator 53 .
[0066] The communication between the vibration sensor and the comparator is realized through the gateway, so that the vibration sensor can transmit the vibration information to the comparator.
[0067] The comparator 53 is configured to be in communication connection with the gateway.
[0068] In some embodiments, the comparator 53 is further configured to receive vibration information, and compare the vibration information with a vibration information threshold.
[0069] For example, the vibration information may be a root mean square velocity value of the device under test, the vibration sensor 10 converts the vibration signal into an electrical signal (root mean square velocity value), and the vibration information threshold may be a root mean square velocity threshold.
[0070] For example, the comparator 53 may be a host computer.
[0071] In some embodiments, the industrial unit vibration monitoring device further includes a first connecting line, which is located between the wireless node 51 and the vibration sensor 52 and is configured to connect the wireless node 51 and the vibration sensor 52 .
[0072] For example, each of the wireless nodes 51 is configured to communicate with one or more vibration sensors 10 , and each of the vibration sensors 10 is configured to communicate with one wireless node 51 .
[0073] In some embodiments, the industrial unit vibration monitoring device further includes a second connection line, which is located between the comparator 53 and the gateway 52 and is configured to connect the comparator 53 and the gateway 52 .
[0074] For example, the comparator 53 and the gateway 52 may implement interactive communication via Ethernet IP (Ethernet Industrial Protocol, Industrial Ethernet) communication protocol.
[0075] In some embodiments, the industrial unit vibration monitoring device further includes: an alarm configured to generate an alarm.
[0076] In some embodiments, the comparator 53 is further configured to trigger an alarm to sound an alarm when the vibration information is greater than a vibration information threshold.
[0077] When the vibration is abnormal, an alarm is sounded to promptly remind relevant staff to handle it and try to avoid more serious consequences (such as downtime, etc.) caused by the abnormality.
[0078] In the above embodiment, the vibration information of the device under test is detected by a vibration sensor, and the vibration information of the device under test is transmitted to a comparator through a wireless node and a gateway. The comparator then compares the size between the vibration information and the vibration information threshold. If the vibration information is greater than the vibration information threshold, the alarm is triggered to sound an alarm. Complete, flexible, reliable, easy-to-operate, and economical industrial unit vibration monitoring is achieved. The operating status of the industrial unit is fed back through vibration monitoring, which effectively ensures that the industrial unit is in a good state. At the same time, the industrial unit vibration monitoring device is also convenient for preventive maintenance of the industrial unit, improves the safe operation cycle of the industrial unit, saves maintenance costs, and reduces the probability of failures and accidents.
[0079] Figure 6 Schematic diagrams showing some embodiments of the industrial machine vibration monitoring system disclosed herein.
[0080] like Figure 6 As shown, the industrial unit vibration monitoring system includes the industrial unit vibration monitoring device in any one of the above embodiments and an industrial unit 61.
[0081] like Figure 6 As shown, each of the wireless nodes 51 is configured to communicate with one vibration sensor 10, and each of the vibration sensors 10 is configured to communicate with one wireless node 51. That is, there is a one-to-one correspondence between the vibration sensors 10 and the wireless nodes 51.
[0082] Of course, multiple vibration sensors 10 can also communicate with the same wireless node 51 , one wireless node 51 can communicate with multiple vibration sensors 10 , and each vibration sensor 10 among the multiple vibration sensors 10 can only communicate with one wireless node 51 .
[0083] like Figure 6 As shown, the industrial machine group 61 may include a plurality of industrial machines, and the motor of each industrial machine is equipped with a vibration sensor 10, which is used to detect the vibration condition of the motor of each industrial machine.
[0084] In some embodiments, the industrial unit 61 may be, for example, a dust removal unit.
[0085] A lot of dust will be generated during tobacco processing, so a dust removal system is needed to purify the dust-containing gas in the working environment. The dust removal unit is one of the main dust removal equipment. Whether the dust removal unit can perform purification safely and reliably will directly affect the safe production and economic benefits of the tobacco factory.
[0086] There are many motors in the dust removal unit, mainly including dust removal discharge air lock, dust removal fan, screw conveyor, etc. During the operation of the motor, abnormal vibration may occur due to various reasons. However, excessive vibration may destroy the running stability of the motor, consume energy, reduce efficiency, deteriorate commutation conditions, damage parts, shorten the life of the motor, and even cause shutdown failure. Because the dust removal unit and the main line equipment are interlocked, if the dust removal unit stops abnormally, it will cause the shutdown of large main equipment in the tobacco factory, such as tofu drying machine, air separation, etc.
[0087] Compared with routine inspections, which result in the factory being unable to formulate a predictive maintenance plan in advance, the dust removal equipment often fails seriously, resulting in obstruction of the production line operation, and even causing the factory to be very passive during the operation and causing huge losses. The vibration sensor detects the vibration of the dust removal unit in real time, and can handle it in time when the vibration is abnormal, effectively ensuring that the dust removal unit is in good condition. At the same time, it is also convenient for preventive maintenance of the dust removal unit, improving the safe operation cycle of the dust removal unit, saving maintenance costs, and reducing the probability of dust removal unit failure and accidents.
[0088] In the above embodiment, the vibration information of the device under test is detected by a vibration sensor, and the vibration information of the device under test is transmitted to a comparator through a wireless node and a gateway. The comparator then compares the size between the vibration information and the vibration information threshold. If the vibration information is greater than the vibration information threshold, the alarm is triggered to sound an alarm. Complete, flexible, reliable, easy-to-operate, and economical industrial unit vibration monitoring is achieved. The operating status of the industrial unit is fed back through vibration monitoring, which effectively ensures that the industrial unit is in a good state. At the same time, the industrial unit vibration monitoring device is also convenient for preventive maintenance of the industrial unit, improves the safe operation cycle of the industrial unit, saves maintenance costs, and reduces the probability of failures and accidents.
