Description

Technical Field

[0001] This application belongs to the field of data monitoring technology, and in particular relates to a monitoring device for rotating equipment, a monitoring method for rotating equipment, and rotating equipment. Background Technology

[0002] With the development of new energy technologies, green electricity technologies such as photovoltaic power generation, wind power generation, and hydropower generation, which have near-zero carbon emissions during the power generation process, are being vigorously promoted. Unlike photovoltaic power generation, wind power generation and hydropower generation require the use of rotating equipment to convert the kinetic energy of wind or water into mechanical energy, and then into electrical energy. During the power generation process using rotating equipment, it is usually necessary to monitor the internal environmental physical parameters of the rotating equipment.

[0003] However, in relevant rotating equipment monitoring solutions, monitoring units with electronic tags are installed in the rotor assembly of the rotating equipment, and a large number of these monitoring units are required. Therefore, to distinguish between monitoring units in different locations, each of these units is typically associated with a unique electronic tag; that is, data transmitted by different monitoring units needs to be differentiated based on their individual tags. This not only requires configuring data processing solutions adapted to the usage scenarios of multiple monitoring units, resulting in high implementation costs, but also necessitates configuring additional electronic tags for the replaced monitoring units during maintenance, further increasing operational costs. Summary of the Invention

[0004] The purpose of this application is to provide a monitoring device, a monitoring method, and a rotating equipment for rotating equipment, aiming to solve the problem that existing rotating equipment monitoring solutions have high implementation and maintenance costs.

[0005] A first aspect of this application provides a monitoring device for a rotating device, disposed in the rotating device, which includes a stator assembly and a rotor assembly. The monitoring device for the rotating device includes:

[0006] The data receiving unit is configured on the stator assembly and is used to receive monitoring data;

[0007] The first monitoring unit and the second monitoring unit are alternately arranged on the rotor assembly;

[0008] The first monitoring unit is used to monitor the physical parameters of the first position on the rotor assembly. During the circumferential rotation of the rotor assembly relative to the stator assembly, the first monitoring data is sent to the data receiving unit. The first monitoring data carries a first preset code.

[0009] The second monitoring unit is used to monitor the physical parameters of the second position on the rotor assembly. During the circumferential rotation of the rotor assembly relative to the stator assembly, it sends second monitoring data to the data receiving unit. The second monitoring data carries a second preset code. The first preset code is different from the second preset code.

[0010] A second aspect of this application provides a method for monitoring a rotating device, applied to the monitoring device for the rotating device provided in the first aspect. The monitoring method includes:

[0011] The monitoring system uses a preset signal to indicate the reception of monitoring data.

[0012] When a preset signal is detected, monitoring data is received; wherein, the monitoring data includes first monitoring data and second monitoring data, the first monitoring data is obtained by the first monitoring unit monitoring the physical parameters of the first position on the rotor assembly, and the second monitoring data is obtained by the second monitoring unit monitoring the physical parameters of the second position on the rotor assembly;

[0013] Obtain a first preset code carried by the first monitoring data and a second preset code carried by the second monitoring data to distinguish between the first monitoring data and the second monitoring data; wherein the first preset code and the second preset code are different.

[0014] In the above scheme, the monitoring data also includes third monitoring data, which is obtained by the third monitoring unit monitoring the physical parameters of the third position on the rotor assembly. The third monitoring data carries a third preset code; wherein, the third preset code is different from the first preset code and different from the second preset code.

[0015] The monitoring method for rotating equipment in the above scheme also includes:

[0016] Based on the first preset code and the second preset code, the received first monitoring data and second monitoring data are deduplicated to obtain the target monitoring data.

[0017] In the above scheme, the monitoring device for the rotating equipment also includes a key phase sensor installed on the stator assembly, and a key phase mark installed on the rotor assembly corresponding to the key phase sensor;

[0018] A key phase sensor is mounted on the stator assembly and is used to generate a key phase signal when a key phase mark is detected.

[0019] Monitoring methods for rotating equipment also include:

[0020] According to the preset numbering strategy, the location number of the target monitoring data is determined based on the key phase signal. The location number is used to indicate the position of the physical parameters corresponding to the target monitoring data on the rotor assembly.

[0021] In the above scheme, the monitoring uses a preset signal to indicate the receipt of monitoring data, including:

[0022] When a key phase signal is detected, it is determined that a preset signal has been detected.

[0023] A third aspect of this application provides a rotating device, which is configured with the monitoring device for the rotating device provided in the first aspect;

[0024] The rotating equipment can be any one of a hydro generator, a wind generator, a tidal generator, or a steam turbine generator.

[0025] The beneficial effects of the embodiments of the present invention compared with the prior art are as follows:

[0026] The aforementioned monitoring device for a rotating device is installed within the rotating device, which includes a stator assembly and a rotor assembly. The monitoring device comprises a data receiving unit, a first monitoring unit, and a second monitoring unit. The data receiving unit is configured on the stator assembly to receive monitoring data. The first and second monitoring units are alternately arranged on the rotor assembly. The first monitoring unit monitors physical parameters at a first position on the rotor assembly and transmits first monitoring data to the data receiving unit during circumferential rotation of the rotor assembly relative to the stator assembly. The second monitoring unit monitors physical parameters at a second position on the rotor assembly and transmits second monitoring data to the data receiving unit during circumferential rotation of the rotor assembly relative to the stator assembly. Since the first monitoring data carries a first preset code and the second monitoring data carries a second preset code, and the first and second preset codes are different, adjacent sets of monitoring data received by the data receiving unit on the stator assembly carry different preset codes. In this way, by alternately setting the first monitoring unit and the second monitoring unit on the rotor assembly, the monitoring data received by the data receiving unit on the stator assembly can carry different preset codes between any two consecutive / adjacent sets of monitoring data, thereby distinguishing the monitoring data corresponding to different monitoring units. In scenarios where multiple monitoring units are required, it is not necessary to configure a one-to-one electronic tag for each monitoring unit, which can meet the need to distinguish different monitoring data in a simpler way. This not only reduces the difficulty of data processing in scenarios with multiple monitoring units, but also reduces implementation and maintenance costs. Attached Figure Description

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] For example, in the relevant rotating equipment monitoring scheme, monitoring units with electronic tags are installed in the rotor assembly of the rotating equipment, and a large number of monitoring units need to be installed.

[0036] For example, rotating equipment used in power generation scenarios has a large rotor assembly. For instance, the rotor diameter of a hydro generator is 10 meters, requiring a large number of monitoring units to be installed on the rotor assembly.

[0037] Therefore, in order to distinguish monitoring units in different locations, multiple monitoring units located in different locations are usually associated with electronic tags one by one. That is, it is necessary to distinguish the data sent by different monitoring units based on different electronic tags. As a result, not only is it necessary to configure a data processing solution adapted to the usage scenarios of multiple monitoring units, which is costly, but also during maintenance, additional electronic tags need to be configured for the monitoring units being replaced, which increases the operation and maintenance costs.

[0038] To address the aforementioned technical problems, this embodiment provides a monitoring device for a rotating device, which is installed within the rotating device. The rotating device includes a stator assembly and a rotor assembly. The monitoring device includes a data receiving unit, a first monitoring unit, and a second monitoring unit. The data receiving unit is configured on the stator assembly and is used to receive monitoring data. The first and second monitoring units are alternately arranged on the rotor assembly. The first monitoring unit monitors physical parameters at a first position on the rotor assembly and sends first monitoring data to the data receiving unit during the circumferential rotation of the rotor assembly relative to the stator assembly. The second monitoring unit monitors physical parameters at a second position on the rotor assembly and sends second monitoring data to the data receiving unit during the circumferential rotation of the rotor assembly relative to the stator assembly. Because the first monitoring data carries a first preset code and the second monitoring data carries a second preset code, and the first and second preset codes are different, adjacent sets of monitoring data received by the data receiving unit on the stator assembly carry different preset codes. In this way, by alternately setting the first monitoring unit and the second monitoring unit on the rotor assembly, the monitoring data received by the data receiving unit on the stator assembly can carry different preset codes between any two adjacent sets of monitoring data, thereby distinguishing the monitoring data corresponding to different monitoring units. In scenarios where multiple monitoring units are required, it is not necessary to configure a one-to-one electronic tag for each monitoring unit, which can meet the need to distinguish different monitoring data in a simpler way. This not only reduces the difficulty of data processing in scenarios with multiple monitoring units, but also reduces implementation and maintenance costs.

[0039] The following provides a detailed description of a monitoring device for rotating equipment provided in this embodiment through specific implementation methods.

[0040] Figure 1 A schematic diagram of the structure of a monitoring device for a rotating device provided in an embodiment of this application is shown. Figure 1 As shown, a monitoring device 100 for rotating equipment is installed in the rotating equipment, which includes a stator assembly 110 and a rotor assembly 120. The monitoring device 100 includes a data receiving unit 10, a first monitoring unit 20, and a second monitoring unit 30. Specifically:

[0041] A data receiving unit 10 is configured on the stator assembly 110. The data receiving unit 10 is used to receive monitoring data. A first monitoring unit 20 and a second monitoring unit 30 are alternately arranged on the rotor assembly 120. The first monitoring unit 20 is used to monitor the physical parameters of a first position on the rotor assembly 120, and sends first monitoring data to the data receiving unit 10 during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110. The first monitoring data carries a first preset code. The second monitoring unit 30 is used to monitor the physical parameters of a second position on the rotor assembly 120, and sends second monitoring data to the data receiving unit 10 during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110. The second monitoring data carries a second preset code. The first preset code and the second preset code are different.

[0042] In this embodiment, a monitoring device 100 for the rotating equipment is installed in the rotating equipment to monitor the physical parameters of the rotating equipment in operation. Specifically, it monitors the physical parameters at different locations of the rotor assembly 120. Here, the physical parameters may specifically be temperature, pressure, strain, etc. Correspondingly, the first monitoring unit 20 and the second monitoring unit 30 may specifically be sensors for monitoring at least one of temperature, pressure, and strain.

[0043] As an example, in a specific implementation, the first monitoring unit 20 and the second monitoring unit 30 can be sensors used to monitor the same physical parameter.

[0044] For example, both the first monitoring unit 20 and the second monitoring unit 30 are temperature sensors / pressure sensors used to monitor temperature / pressure. The first monitoring unit 20 and the second monitoring unit 30 are alternately arranged on the rotor assembly 120. The first monitoring unit 20 can monitor the temperature / pressure at a first position on the rotor assembly 120, and the second monitoring unit 30 can monitor the temperature / pressure at a second position on the rotor assembly 120.

[0045] For example, both the first monitoring unit 20 and the second monitoring unit 30 are strain force sensors used to monitor strain force. The first monitoring unit 20 and the second monitoring unit 30 are alternately arranged on the rotor assembly 120. The first monitoring unit 20 can monitor the strain force at a first position on the rotor assembly 120, and the second monitoring unit 30 can monitor the strain force at a second position on the rotor assembly 120.

[0046] It is understandable that, in specific implementations, the first monitoring unit 20 and the second monitoring unit 30 can also be sensors used to monitor different physical parameters. For example, the first monitoring unit 20 can be a temperature sensor for monitoring temperature, and the second monitoring unit 30 can be a pressure sensor / strain sensor for monitoring pressure / strain. The first monitoring unit 20 and the second monitoring unit 30 are alternately arranged on the rotor assembly 120. The first monitoring unit 20 can monitor the temperature at a first position on the rotor assembly 120, and the second monitoring unit 30 can monitor the pressure / strain at a second position on the rotor assembly 120.

[0047] As another example, in a specific implementation, the first monitoring unit 20 and the second monitoring unit 30 can use the same sensor to monitor the temperature, pressure, and strain of the rotor assembly 120. Here, when the first monitoring unit 20 and the second monitoring unit 30 use the same sensor, the sensor can include a sensing element made of a sensitive material and an LC resonant circuit. This sensing element can be sensitive to ambient temperature, pressure, and strain simultaneously, generating electrical signals within different ranges. The LC resonant circuit can then generate corresponding wireless signals based on these electrical signals and transmit them to the data receiving unit 10. The data receiving unit 10 then determines the specific values ​​of the physical parameters represented by these wireless signals.

[0048] In all embodiments of this application, during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110, the first monitoring unit 20 sends first monitoring data to the data receiving unit 10, and the second monitoring unit 30 sends second monitoring data to the data receiving unit 10. Since the first monitoring data carries a first preset code and the second monitoring data carries a second preset code, and the first preset code and the second preset code are different, the data receiving unit 10 can distinguish between the first monitoring data and the second monitoring data according to the preset code corresponding to the received data.

[0049] As one embodiment, the first monitoring unit 20 and the second monitoring unit 30 are alternately arranged along the circumference of the rotor assembly 120. Figure 1 As shown, since the first monitoring unit 20 and the second monitoring unit 30 are alternately arranged along the circumference of the rotor assembly 120, for the second monitoring unit 30 closest to the data receiving unit 10, its adjacent monitoring unit in any direction is the first monitoring unit 20. In this way, the data receiving unit 10 can receive the first monitoring data sent by the first monitoring unit 20 before and / or after receiving the second monitoring data sent by the second monitoring unit 30. Based on this, the preset codes carried by the data receiving unit 10 are different between any two consecutive adjacent sets of monitoring data received.

[0050] In some embodiments, when the radius / diameter of the rotor assembly 120 is large, the data receiving unit 10 has limited ability to receive wireless signals. Therefore, by setting an appropriate signal receiving range, the rotor assembly 120 can receive monitoring data sent by a monitoring unit close to it during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110.

[0051] For example, during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110, when the first position is within the preset receiving range of the data receiving unit 10, the data receiving unit 10 can receive the first monitoring data sent by the first monitoring unit 20. Similarly, during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110, when the second position is within the preset receiving range of the data receiving unit 10, the data receiving unit 10 can receive the second monitoring data sent by the second monitoring unit 30.

[0052] Referring to the above example, taking the first monitoring unit 20 and the second monitoring unit 30 as examples where the same sensor is used, the sensor includes a sensing element made of a sensitive material and an LC resonant circuit. As one possible implementation, the first monitoring unit 20 can select an LC resonant circuit to generate a carrier wave in a first frequency band, and the second monitoring unit 30 can select an LC resonant circuit to generate a carrier wave in a second frequency band, with the first and second frequency bands being different. That is, by using different preset codes corresponding to different frequency bands, when the first monitoring unit 20 sends a first wireless signal to the data receiving unit 10, the band of the first wireless signal is the first preset code; when the second monitoring unit 30 sends a second wireless signal to the data receiving unit 10, the band of the second wireless signal is the second preset code.

[0053] As another possible implementation, LC resonant circuits can be selected in the first monitoring unit 20 and the second monitoring unit 30 to generate carriers in the same frequency band. The carrier generated by the first monitoring unit 20 carries a first preset code, and the carrier generated by the second monitoring unit 30 carries a second preset code. After the first monitoring unit 20 sends a wireless signal to the data receiving unit 10 at a first moment, the data receiving unit 10 receives the wireless signal sent by the second monitoring unit 30 at a second moment. The data receiving unit 10 can distinguish between the first monitoring data and the second monitoring data based on the first and second preset codes carried in the two sets of wireless signals.

[0054] In all embodiments of this application, the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110 refers to the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110 under the action of an external force. Here, the object of the external force can be the rotor assembly 120. Figure 1As shown, the rotor assembly 120 rotates circumferentially relative to the stator assembly 110. Specifically, the rotor assembly 120 rotates circumferentially relative to the stator assembly 110 in a first direction (i.e., clockwise) or in a second direction (i.e., counterclockwise). No restrictions are imposed here.

[0055] It is easy to understand that, in Figure 1 In the example shown, during the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110 in any direction, the data receiving unit 10 is closest to either the first monitoring unit 20 or the second monitoring unit 30 at any given moment.

[0056] Based on the above example, as one possible implementation, only one target monitoring unit exists within the preset receiving range of the data receiving unit 10 at any given time. This target monitoring unit can be either the first monitoring unit 20 or the second monitoring unit 30. Therefore, the data receiving unit 10 can receive only the first monitoring data sent by the first monitoring unit 20 or the second monitoring data sent by the second monitoring unit 30 at any given time.

[0057] As another possible implementation, at any given time, there may be at most two monitoring units within a preset receiving range of the data receiving unit 10, namely, the first monitoring unit 20 and the second monitoring unit 30. Based on this, the data receiving unit 10 may receive at most two sets of monitoring data at any given time, namely, the first monitoring data sent by the first monitoring unit 20 and / or the second monitoring data sent by the second monitoring unit 30.

[0058] In the above scheme, by alternately setting the first monitoring unit 20 and the second monitoring unit 30 on the rotor assembly 120, any two adjacent sets of monitoring data received by the data receiving unit 10 on the stator assembly 110 can carry different preset codes, thereby distinguishing the monitoring data corresponding to different monitoring units. Therefore, in scenarios requiring multiple monitoring units, it is not necessary to configure a one-to-one electronic tag for each monitoring unit, thus meeting the need to distinguish different monitoring data in a simpler way and reducing implementation costs. Furthermore, since the first monitoring unit 20 and the second monitoring unit 30 are alternately set on the rotor assembly 120, the monitoring data received by the data receiving unit 10 can be distinguished based on the first and second preset codes, thereby reducing the difficulty of data processing in scenarios with multiple monitoring units. Also, in scenarios where the monitoring units on the rotor assembly 120 are being maintained, the preset code of the monitoring unit to be replaced can be determined based on the preset codes of other adjacent monitoring units around the unit to be replaced, reducing maintenance costs.

[0059] Figure 2 A schematic diagram of the structure of a monitoring device for a rotating device according to another embodiment of this application is shown. Figure 2 As shown, as an example, with Figure 1 The difference in this embodiment is that the monitoring device 100 for the rotating equipment further includes a third monitoring unit 40. Specifically:

[0060] The third monitoring unit 40 is positioned between the first monitoring unit 20 and the second monitoring unit 30. This third monitoring unit 40 monitors the physical parameters at a third position on the rotor assembly 120. During the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110, it sends third monitoring data to the data receiving unit 10. This third monitoring data carries a third preset code. The third preset code differs from both the first and second preset codes.

[0061] It is understood that in all embodiments of this application, the first position, the second position, and the third position are used to distinguish or characterize the positions of the first monitoring unit 20, the second monitoring unit 30, and the third monitoring unit 40 on the rotor assembly 120. In specific implementations, the third position may be different from the first position and / or the second position. Of course, in order to better obtain the temperature distribution, pressure distribution, and strain distribution at different positions on the rotor assembly 120, the third position may also be a position on the rotor assembly 120 that partially overlaps with the first position and / or the second position.

[0062] It is understood that, in specific implementations, the third monitoring unit 40 in this embodiment can be implemented using the same sensor as the first monitoring unit 20 and / or the second monitoring unit 30. For details, please refer to [link to relevant documentation]. Figure 1 Examples of the first monitoring unit 20 and / or the second monitoring unit 30 in the corresponding embodiments will not be repeated here.

[0063] As one embodiment, the monitoring device 100 for rotating equipment further includes a data processing unit (not shown in the figure).

[0064] In this embodiment, the data processing unit is connected to the data receiving unit 10. The data processing unit is used to perform deduplication processing on the received monitoring data according to the preset code carried by the received monitoring data to obtain the target monitoring data.

[0065] It should be noted that, considering the complex magnetic field environment inside the rotating equipment, multiple readings may occur. That is, in actual use, the first monitoring unit 20, the second monitoring unit 30, and the third monitoring unit 40 installed on the rotor assembly 120 may be sending monitoring data to the data receiving unit 10 at any given time. Alternatively, when the rotor assembly 120 rotates at a high speed, the data receiving unit 10 may receive the same monitoring data from the same monitoring unit at two similar times. Based on this, the data processing unit can perform deduplication processing on the received monitoring data according to the preset code carried by the data to obtain the target monitoring data. Here, the target monitoring data generally refers to the data after deduplication of the received monitoring data, and may include monitoring data sent by at least one of the first monitoring unit 20, the second monitoring unit 30, and the third monitoring unit 40.

[0066] Figure 3 This illustration shows an example implementation of a monitoring device for a rotating device according to an embodiment of this application. Figure 1 .exist Figure 3 In the example shown, dashed lines are used to indicate different position ranges and their correspondence with the monitoring units in order to facilitate the distinction between the first, second, and third positions. It is understood that in practical implementation, when using the first monitoring unit 20, the second monitoring unit 30, and the third monitoring unit 40 to monitor the physical parameters at any position on the rotor assembly 120, the monitoring range of each monitoring unit can be known. That is, in actual implementation, different positions can be divided based on the monitoring range of the monitoring units. Figure 3 The example shown does not restrict the specific division of the first, second, and third positions.

[0067] exist Figure 3 In this configuration, the data processing unit 50 can be mounted on the stator assembly 110 and connected to the data receiving unit 10, thereby receiving the monitoring data received by the data receiving unit 10. The data processing unit 50 performs deduplication processing on the received monitoring data by using a preset code carried by the monitoring data to obtain the target monitoring data.

[0068] Figure 4 This illustration shows an example implementation of a monitoring device for a rotating device according to an embodiment of this application. Figure 2 As an example, in Figure 4 In the example shown, the monitoring device 100 of the rotating equipment further includes: a key phase sensor 60 disposed on the stator assembly 110, and a key phase mark 70 disposed on the rotor assembly 120 corresponding to the key phase sensor 60.

[0069] In this embodiment, the key phase sensor 60 generates a key phase signal when it detects the key phase mark 70. Here, the key phase signal is used to mark the number of circumferential rotations of the rotor assembly 120 relative to the stator assembly 110. That is, whenever the key phase sensor 60 generates a key phase signal, it indicates that the rotor assembly 120 has completed one circumferential rotation relative to the stator assembly 110.

[0070] In a practical implementation, the key phase sensor 60 can be a distance monitoring probe, and the key phase mark 70 can be a protrusion or recess on the rotor assembly 120. When the distance between the distance monitoring probe and the rotor assembly 120 changes, the distance monitoring probe generates a pulse signal. The timing of this pulse signal indicates the start / end of the circumferential rotation of the rotor assembly 120 relative to the stator assembly 110. Therefore, by counting the pulses, the shaft rotational speed can be measured. Furthermore, by comparing this pulse signal with the vibration signal of the rotor assembly 120, the phase angle of the vibration can be determined, which can be used for shaft dynamic balance analysis, fault analysis, and diagnostic analysis of rotating equipment.

[0071] As an example, in Figure 4 In the example shown, the data processing unit 50 is connected to the key phase sensor 60. The data processing unit 50 is also used to determine the position number of the target monitoring data based on the key phase signal according to a preset numbering strategy. The position number is used to indicate the position of the physical parameter corresponding to the target monitoring data on the rotor assembly 120.

[0072] In this embodiment, the key phase signal is used to mark the start / end of the received monitoring data. Specifically, since each time the key phase sensor 60 generates a key phase signal, it indicates that the rotor assembly 120 has rotated circumferentially one revolution relative to the stator assembly 110, the received monitoring data can be numbered using one revolution of the rotor assembly 120 relative to the stator assembly 110 as a unit cycle. Here, when numbering the monitoring data, the numbering order can be the same as the order in which the monitoring data was received, numbering from smallest to largest or from largest to smallest; there is no restriction here.

[0073] by Figure 4Taking the rotor assembly 120's circumferential rotation relative to the stator assembly 110 in the first direction as an example, at the first moment, the key phase sensor 60 detects the key phase mark 70 and generates a key phase signal. Simultaneously, the data receiving unit 10 receives the second monitoring data sent by the second monitoring unit 30. At the second moment after the first moment, the position closest to the data receiving unit 10 is the third position, meaning the data receiving unit 10 receives the third monitoring data sent by the third monitoring unit 40. At the third moment after the second moment, the position closest to the data receiving unit 10 is the first position, meaning the data receiving unit 10 receives the second monitoring data sent by the first monitoring unit 20. And so on. After the rotor assembly 120 has rotated one full circumferential rotation relative to the stator assembly 110 in the first direction, that is, at the eighth moment after the seventh moment, the position closest to the data receiving unit 10 is the third position, meaning the data receiving unit 10 receives the third monitoring data sent by the third monitoring unit 40. At this time, after the data receiving unit 10 deduplicates the received data, it can obtain a total of eight sets of target monitoring data. That is, the second monitoring data, the third monitoring data, the first monitoring data, the third monitoring data, the second monitoring data, the third monitoring data, the first monitoring data, and the third monitoring data. The data processing unit 50 determines the location number of the target monitoring data according to a preset numbering strategy based on the key phase signal, that is, determines the location number of the above eight sets of target monitoring data: the number #1 for the second monitoring data, the number #2 for the third monitoring data, the number #3 for the first monitoring data, the number #4 for the third monitoring data, the number #5 for the second monitoring data, the number #6 for the third monitoring data, the number #7 for the first monitoring data, and the number #8 for the third monitoring data. For example... Figure 4 As shown, numbers #1 to #8 can all be used to indicate the actual position of the physical parameters corresponding to the target monitoring data on the rotor assembly 120.

[0074] This application also provides a method for monitoring rotating equipment, applied to... Figures 1 to 4 The monitoring device for the rotating equipment shown.

Figure 1 The data receiving unit 10 in the middle can also be Figure 3 or Figure 4 The data processing unit 50 is located within the system. In specific implementations, the entity executing the monitoring method for the rotating equipment can also be a host computer, a terminal, etc. This is not limited here; it is achieved by connecting to the data receiving unit 10.
