[0022] As can be seen from the background technology, in the daily operation of a factory, the inspection and maintenance of motor sets is an important task.

[0023] However, for small and medium-sized factories, due to funding constraints, manual inspections are still the most common way to maintain motor groups. Manual inspections are inefficient, cumbersome, and prone to errors. Once errors occur, motor failures will cause the factory to be blocked and have a negative impact on the factory.

The staff can also view the early warning data and early warning trend chart of the motor through the terminal application to further understand the operating status of the motor, which can at least improve the maintenance efficiency of the staff.

[0031] Figure 1 A schematic diagram of the structure of a motor monitoring system provided in an embodiment of the present disclosure.

[0032] refer to Figure 1 The embodiment of the present disclosure provides a motor monitoring system 100, including a monitoring device 101, which is disposed on a motor 200 and is configured to collect operating data of the motor 200, and to generate and store the operating data of the motor 200. The motor detection system 100 also includes a terminal application 102, which is wirelessly connected to the monitoring device 101, and is configured to wirelessly access the operating data, obtain the operating data based on a time period, compare the operating data with a corresponding threshold parameter, and generate an early warning mark and an early warning trend chart.

[0033] The monitoring device 101 is used to monitor the operating status of the motor 200 . Each monitoring device 101 corresponds to one motor 200 . The staff can view the operating data stored in each monitoring device 101 to monitor the operating status of the motor 200 .

[0034] Figures 2 to 6 Some other structural schematic diagrams of the motor monitoring system 100 provided in the embodiments of the present disclosure.

[0035] In some embodiments, reference Figure 2 The monitoring device 101 includes a data acquisition unit 111, a data processing unit 121 and a data storage unit 131. The data acquisition unit 111, the data processing unit 121 and the data storage unit 131 work together to realize the functions of the monitoring device 101 to collect data, process data and store data. The data acquisition unit 111 is used to collect operating parameters of the motor 200 during operation, such as the temperature of the motor 200 or the vibration state of the motor 200. The data processing unit 121 is used to process the basic data collected by the data acquisition unit 111 into intuitive and visible data to reflect the operating state of the motor 200. The data storage unit 131 is used to store the data obtained after processing by the data processing unit 121 for later viewing. After the terminal application 102 is wirelessly connected to the detection device, it can access the data stored in the data storage unit 131 to view the historical operating state of the motor 200.

[0036] In some embodiments, reference Figure 3The data acquisition unit 111 may include a vibration data acquisition unit 112. The vibration data acquisition unit 112 acquires vibration data of the motor 200. For example, the vibration data acquisition unit 112 may acquire vibration acceleration data of the motor 200. Subsequently, the vibration acceleration data of the motor 200 may be processed into vibration velocity data of the motor 200 in the data processing unit 121, so as to realize an intuitive representation of the vibration data of the motor 200 during operation, so as to facilitate the staff to view and understand the operating status of the motor 200.

[0037] In some embodiments, the data acquisition unit 111 may further include a temperature data acquisition unit 113 . The temperature data acquisition unit 113 acquires temperature data of the motor 200 .

[0038] In some embodiments, the vibration data acquisition unit 112 may include an acceleration sensor. The acceleration sensor may be used to collect vibration acceleration data of the motor 200. The data processing unit 121 may process the vibration acceleration data into vibration velocity data to obtain the vibration state of the motor 200 during operation. The piezoelectric element in the acceleration sensor will generate an electric charge after being subjected to an inertial force, and the acceleration value may be obtained by calculating the amount of charge. The acceleration sensor may include a uniaxial acceleration sensor, a biaxial acceleration sensor, or a triaxial acceleration sensor. Taking a triaxial acceleration sensor as an example, when the triaxial acceleration sensor is installed on the motor 200, the vibration acceleration of the motor 200 on the x-axis, y-axis, and z-axis may be obtained. The frequency at which the acceleration sensor measures and updates the vibration acceleration of the motor 200 is greater than the frequency at which the single-chip microcomputer reads data, so as to avoid the single-chip microcomputer reading duplicate data, thereby avoiding confusion in the acceleration data collected by the acceleration sensor. For example, when the frequency of the single chip microcomputer reading data is 1kHz, that is, 1ms, the frequency of the acceleration sensor measuring and updating the vibration acceleration of the motor 200 can be set to 2kHz, 3kHz, 4kHz, 5kHz or 6kHz, etc. When the single chip microcomputer reads data, 1024 data can be continuously collected and put into the time domain array to facilitate the subsequent processing of the vibration acceleration data.

[0039] In some embodiments, the temperature data acquisition unit 113 may include a temperature measurement circuit. The temperature measurement circuit can express the temperature data of the motor 200 in the form of a voltage value, and the data processing unit 121 then converts the voltage value obtained by the temperature measurement circuit into a resistance value, and calculates the temperature data of the motor 200 based on the resistance value to obtain the temperature state of the motor 200 during operation. The temperature measurement circuit may include a PT100 precision temperature measurement circuit. The PT100 precision temperature measurement circuit uses a platinum resistor as a sensitive element, has the advantages of high accuracy, reliable performance and good stability, and is suitable for various types of motor groups with complex operating conditions. When collecting the temperature data of the motor 200, the temperature measurement circuit can obtain the voltage measured by the temperature measurement circuit through the ADC (Analog-Digital Converter) in the temperature measurement circuit, and then convert the voltage into the temperature data of the motor 200 through the temperature data processing unit.

[0040] In some embodiments, the data acquisition unit 111 may include one, two, three, four or five temperature data acquisition units 113. It is understandable that the number and arrangement positions of the temperature data acquisition units 113 can be designed according to the detection requirements of the staff. For example, when the staff needs to monitor the temperature of two different positions on a motor 200, a temperature data acquisition unit 113 can be designed to be located at one position, and another temperature data acquisition unit 113 can be designed to be located at another position. The two temperature data acquisition units 113 can be connected to two corresponding temperature data processing units to process the temperature data collected by the two temperature data acquisition units 113.

[0041] In some embodiments, the data processing unit 121 may include a vibration data processing unit 122. The vibration data processing unit 122 may be connected to the vibration data acquisition unit 112, and the vibration data processing unit 122 may be used to process the vibration acceleration data collected by the acceleration sensor to generate vibration velocity data. When the vibration data processing unit 122 processes the vibration acceleration data, it may first perform de-trending processing on the original vibration acceleration data collected by the vibration data acquisition unit 112 to remove the accumulated errors in the original data. Then use FFT (Fast Fourier Transform) to convert the vibration acceleration data from the time domain to the frequency domain. The conversion process may include: using the integral property of Fourier transform to perform frequency domain conversion and phase conversion to complete integration, converting the acceleration curve into a velocity curve, and the integral of the frequency domain needs to use the integral property of Fourier transform again:

[0042]

[0043] If F(0) = 0, or exists and is finite, then the above formula can be simplified to: Except when ω=0, it is equal to 0 at other times. Since the vibration acceleration with a frequency of 0 is a DC component, it will interfere with the vibration acceleration data, so it needs to be filtered out so that F(0)=0. It can be calculated using the following formula:

[0044]

[0045] After processing the vibration acceleration data, the velocity signal is obtained. The velocity signal can be converted from the frequency domain to the time domain using the inverse FFT transform. The root mean square of the velocity signal is calculated to obtain the average vibration energy, which is the vibration velocity. The vibration velocity can also be averaged to reduce the error.

[0046] In other embodiments, the data processing unit 121 may further include a temperature data processing unit 123. The temperature data processing unit 123 may be connected to the temperature data acquisition unit 113, and the temperature data processing unit 123 may be used to process the voltage value measured by the temperature measurement circuit to generate temperature data. When the temperature data processing unit 123 processes the data collected by the temperature data acquisition unit 113, the voltage may be converted into resistance, and then the temperature of the motor 200 may be calculated by comparing the temperature resistance comparison table corresponding to the temperature measurement circuit.

[0047] In some embodiments, the data storage unit 131 can be connected to the data processing unit 121. The data storage unit 131 can be used to store vibration speed data and temperature data. After the terminal application 102 is wirelessly connected to the detection device, the vibration speed data and temperature data in the data storage unit 131 are accessed and read, and then the vibration speed data can be compared with the vibration speed warning threshold parameter, and the temperature data can be compared with the temperature warning threshold parameter to obtain the vibration speed warning trend and the temperature warning trend. The data storage unit 131 allows the staff to reduce the number of inspections, and change the work procedure of frequently checking the monitoring data into checking the damage trend of the motor 200 in combination with historical data for a period of time, and make maintenance decisions based on the damage trend of the motor 200. For example, the staff finds that the operating capacity of the motor 200 has dropped significantly in recent times by checking the historical data, and can decide to shut down the motor 200 for maintenance and replacement of parts or replace a new motor 200 in combination with the actual situation of the motor 200. When the operating data is to be stored in the data storage unit 131, a circular queue can be defined that only enters one historical data when entering the queue, and outputs one page of historical data when leaving the queue, so as to facilitate reading historical data.

[0048] In some embodiments, the storage medium of the data storage unit 131 may be FLASH, a disk, DRAM, ROM, or MRAM.

[0049] In some embodiments, reference Figure 4The monitoring device 101 may further include a time encapsulation unit 141 and a storage unit 151. The time encapsulation unit 141 may be connected to the data acquisition unit 111, and the time encapsulation unit 141 is used to generate encapsulated data, and the encapsulated data includes operation data and a timestamp corresponding to the operation data. The storage unit 151 is connected to the time encapsulation unit 141, and the storage unit 151 may be used to store the encapsulated data. For example, the time encapsulation unit 141 may encapsulate the operation data collected by the data acquisition unit 111 with the time data when the operation data is collected to form encapsulated data, and the time data may be the RTC time converted into a Unix timestamp. The storage unit 151 stores the operation data and the encapsulated data formed by the corresponding RTC time, and the storage unit 151 may be connected to the data storage unit 131. When reading the operation data in the data storage unit 131, a binary query may be performed on the operation data according to the time data of the encapsulated data to determine the index of the operation data in the record queue, thereby improving the retrieval efficiency.

[0050] In some embodiments, reference Figure 5 The monitoring device 101 may further include a power supply unit 161, which includes a main battery and a backup battery. The power supply unit 161 is used to supply power to the monitoring device 101, for example, to supply power to the data acquisition unit 111 of the monitoring device 101 so that the data acquisition unit 111 collects the original operation data on the motor 200, or to supply power to the data processing unit 121 of the monitoring device 101 so that the data processing unit 121 processes the original operation data into operation data that can intuitively display the operation status of the motor 200, or to supply power to the data storage unit 131 of the monitoring device 101 so as to store the operation data of the motor 200 for subsequent viewing. When the monitoring device 101 is powered by the power supply unit 161, it avoids the monitoring device 101 from being electrically connected to the external power supply environment, thereby avoiding the monitoring device 101 from operating faults due to improper waterproofing in the external power supply environment, which is beneficial to improving the safety of the monitoring device 101, and is also beneficial to avoiding the interruption of power supply to the monitoring device 101 when the external power supply environment is closed due to power outages or maintenance, thereby avoiding the interruption of monitoring of the monitoring device 101, and further promoting the stable monitoring work of the staff. When the main battery can normally power the monitoring device 101, the monitoring device 101 is powered by the main battery. When the main battery is exhausted, the monitoring device 101 switches to being powered by the backup battery. The battery type may include lithium-ion batteries, alkaline batteries, or rechargeable batteries.

[0051] In some embodiments, the monitoring device 101 is further configured to generate queue information of the last entered operation data and store the current threshold parameters, device name and queue information when the monitoring device 101 is switched to be powered by a backup battery. For example, when the storage medium of the data storage unit 131 is FLASH, since FLASH has the characteristic that it must be erased before it can be written, in order to avoid the data tail of the FLASH being reinitialized after the monitoring device 101 is powered off, thereby avoiding the data in the FLASH from being erased, the data storage unit 131 can be configured to generate queue information when the last operation data is entered when the monitoring device 101 is switched to be powered by a backup battery, and save this queue information in the data storage unit 131, so as to be used to restore the direction of the head and tail of the operation data in the FLASH after the monitoring device 101 is powered off and re-powered. The data storage unit 131 can also save the device name of the motor 200 and the currently set threshold parameters to prevent the device name and threshold parameters from being restored to the initial values ​​after the monitoring device 101 is powered off and repowered, thereby avoiding confusion in the terminal application 102 when processing the warning information and affecting the operating personnel's viewing of the operating status of the motor 200.

[0052] The terminal application 102 is connected to the monitoring device 101 by wireless communication, and the terminal application 102 can access the information stored in the monitoring device 101. The carrier medium of the terminal application 102 can be a terminal device, such as a mobile phone or an industrial PDA (Personal Digital Assistant).

[0053] In some embodiments, the terminal application 102 can communicate with the monitoring device 101 wirelessly via BLE (Bluetooth Low Energy). The communication range of BLE can cover the factory area, and the staff can simultaneously connect to the monitoring devices 101 on the motors 200 in various positions in the factory at a suitable location in the factory, without having to walk back and forth to each motor 200 for detection, thereby improving the maintenance efficiency of the staff. In addition, BLE has the characteristics of low power consumption, which is conducive to extending the use time of the motor monitoring system 100.

[0054] In some embodiments, reference Figure 6 The terminal application 102 further includes a reading unit 132 and a display unit 142. After the terminal application 102 is connected to the monitoring device 101 via wireless communication, the reading unit 132 can read the data in the data storage unit 131 of the monitoring device 101, and the display unit 142 cooperates with the reading unit 132 to display the data in the data storage unit 131.

[0055] For example, the reading unit 132 can be used to read the power of the power supply unit 161 of the monitoring device 101, such as the power of the main battery and / or the power of the backup battery. The display unit 142 can be used to display the power of the power supply unit 161, such as the power of the main battery and / or the power of the backup battery, and the display method can be in the form of percentage, or the display method can also be the estimated duration of the current power available.

[0056] For another example, the reading unit 132 can also be used to read the operating data stored in the data storage unit 131 of the monitoring device 101, such as the vibration speed data or temperature data of the motor 200. The display unit 142 can be used to display the vibration speed data of the motor 200, for example, it can include the vibration speed data of the x-axis, the vibration speed data of the y-axis, and the vibration speed data of the z-axis. The display unit 142 can also be used to display the temperature data of the motor 200, for example, it can include the temperature data on one, two, three or four temperature monitoring points of the motor 200.

[0057] The display unit 142 can also be used to display the warning information obtained by comparing the operation data read by the reading unit 132 with the threshold parameter. For example, the x-axis vibration speed data read by the reading unit 132 is greater than the threshold parameter of the vibration speed data, that is, the x-axis vibration of the motor 200 reaches the alarm standard, and the display unit 142 needs to output the alarm information. The alarm information can be in the form of a flashing alarm mark suspended on the display menu, or a vibration information sent to the terminal device carrying the terminal application 102, or a color change mark of the corresponding parameter on the display menu, such as changing from green to red, or from light color to dark color.

[0058] Figures 7 to 10 Some page diagrams of the display unit 142 provided in the embodiment of the present disclosure.

[0059] In some embodiments, the display menu of the display unit 142 may include an overview page, a trend graph page, a historical data page, and a parameter setting page. Figure 7The information displayed on the overview page may include the device name of the currently accessed monitoring device 101, the x-axis real-time vibration velocity data, y-axis real-time vibration velocity data, z-axis real-time vibration velocity data, real-time temperature data at the first temperature detection point, real-time temperature data at the second temperature detection point, and the power supply unit of the motor 200, etc. The overview page may also include corresponding icons that can lead to the trend chart page, historical data page, and parameter setting page. Among them, the x-axis real-time vibration velocity data, the y-axis real-time vibration velocity data, and the z-axis real-time vibration velocity data can be displayed as numerical values ​​in mm / s. The real-time temperature data at the first temperature detection point and the real-time temperature data at the second temperature detection point can also be displayed as numerical values ​​in °C.

The trend chart page can include the normal data page and the alarm data page of the motor 200.

The alarm data page can include the temperature alarm data trend chart and the vibration data trend chart of the motor 200. The trend chart page can also include the time period mark of the current read data, and the display mode of the time period mark can be year / month / day.

[0063] Fig.11 A page diagram of a basic service module provided in an embodiment of the present disclosure.

[0064] In some embodiments, reference Fig.11 , the terminal application 102 may include a basic service module. The basic service module is used to set up a basic framework for the terminal application 102. For example, multiple feature words can be created under the basic service module to configure the terminal application 102 for real-time data transmission, or to read and write RTC time, or to configure the terminal application 102 to read the historical operation data stored in the monitoring device 101 according to time periods, so that the staff can monitor the historical operation status of the motor 200 within a period of time. When configuring the terminal application 102 for real-time data transmission, the Notify permission can be used. After the terminal application 102 subscribes to the monitoring device 101, each time the terminal application 102 is connected to the corresponding monitoring device 101, the terminal application 102 can automatically collect the real-time data of the monitoring device 101 without manual operation, thereby improving the efficiency of data transmission. When configuring the read and write RTC time and configuring the terminal application 102 to read the historical operation data stored in the monitoring device 101 according to time periods, the Read&WriteWithoutResponse permission can be used. After the terminal application 102 subscribes to the monitoring device 101, each time a command is written on the basic service module, the monitoring device 101 will actively read the response. When the staff reads the historical operation data stored in the monitoring device 101 according to the time period, they can enter the start and end time of the time period on the terminal application 102. The terminal application 102 sends the start and end time and queries the head and tail indexes of the historical data. The terminal application 102 sends the index and reads it in multiple times according to the maximum number of transmission bytes of BLE. Finally, the read historical operation data is processed into a trend chart or a record table, and displayed on the display unit 142. The staff can switch the display menu on the display unit 142 to intuitively see the trend chart or record table.

[0065] The page of the basic service module may include the user name, service quantity, signal strength, and universal unique identifier. The page of the basic service module may also include multiple feature words. For example, create a feature word named FEC1, configure FEC1 to use the Notify permission to perform real-time data transmission of the terminal application 102. For another example, create a feature word named FEC2, configure FEC2 to use the Read&WriteWithoutResponse permission, so that the terminal application 102 can read and write RTC time. For another example, create a feature word named FEC3, configure FEC3 to use the Read&WriteWithoutResponse permission, so as to configure the terminal application 102 to read the historical operation data stored in the monitoring device 101 according to the time period. It can be understood that when it is necessary to configure the basic service module to provide services, a feature word can be created on the page of the basic service module to configure the corresponding service, and the created feature word can display the name and the permission used on the page of the basic service module. The page of the basic service module may also include a switch for controlling the terminal application 102 to connect to the monitoring device 101. Click the switch to connect the terminal application 102 to the monitoring device 101. Click the switch again to disconnect the terminal application 102 from the monitoring device 101.

[0066] Fig.12 as well as Fig.13 Some further structural schematic diagrams of the motor monitoring system 100 provided in the embodiments of the present disclosure.

[0067] In some embodiments, reference Fig.12The terminal application 102 may further include a parameter setting unit 152, which may be located in the basic service module. The parameter setting unit 152 may be used to modify various threshold parameters in the motor 200, such as the threshold parameters of the x-axis vibration speed, the threshold parameters of the y-axis vibration speed, the threshold parameters of the z-axis vibration speed, the threshold parameters of the power of the power supply unit 161, or the threshold parameters of the temperature of each temperature monitoring site on the motor 200. Among them, the units of the threshold parameters of the x-axis vibration speed, the threshold parameters of the y-axis vibration speed, and the threshold parameters of the z-axis vibration speed may be mm / s, and the units of the threshold parameters of the temperature of each temperature monitoring site on the motor 200 may be °C. The parameter setting unit 152 may also be used to modify the device name. When the number of motors 200 in the plant is greater than or equal to two, the device name of the motor 200 corresponding to each monitoring device 101 may be modified by the parameter setting unit 152 to distinguish between two or more motors 200. When the staff connects to the monitoring device 101 via wireless communication in the factory, they can locate different monitoring devices 101 by different device names, thereby reading the corresponding motor 200 operation data to improve the staff's maintenance efficiency. The configuration parameter setting unit 152 can use the Read & Write Without Response permission. After the terminal application 102 subscribes to the monitoring device 101, each time a command is written to the parameter setting unit 152, the monitoring device 101 will actively read the response.

[0068] In some embodiments, reference Fig.13 The motor monitoring system 100 may further include a control module 103. The control module 103 is used to control the operation mode of the monitoring device 101. For example, when the monitoring device 101 is in the operation cycle, the control module 103 controls the monitoring device 101 to be in the operation state, and the data acquisition unit 111, the data processing unit 121 and the data storage unit 131 of the monitoring device 101 are all working. When the detection device is outside the operation cycle, the control module 103 controls the monitoring device 101 to be in the dormant state, the data acquisition unit 111 and the data processing unit 121 of the monitoring device 101 are dormant, data acquisition and data processing are stopped, and the data storage unit 131 keeps working, so as to respond to the request of the terminal application 102 in time. In this way, the operation power consumption of the monitoring device 101 is reduced, which is conducive to extending the use time of the monitoring device 101. The staff can change the operation mode of the monitoring device 101 through the control module 103, such as changing the operation state duration or the dormant state duration of the monitoring device 101, so as to better adapt to different types of motors 200 and avoid the data monitored by the monitoring device 101 being too redundant.

[0069] The motor monitoring system 100 provided by the above disclosed embodiment includes not only a monitoring device 101 for monitoring the operation of the motor 200, but also a terminal application 102 wirelessly connected to the monitoring device 101. The monitoring device 101 is arranged on the motor 200, and can monitor the operation status of the motor 200 in real time. The monitoring device 101 can collect the real-time operation data of the motor 200, generate and store the operation data of the motor 200. The terminal application 102 is connected to the monitoring device 101 through wireless communication, which is convenient for the staff to directly view the real-time operation data of the motor 200 on the terminal application 102, without having to view and record on each motor 200 group, thereby improving the efficiency of the inspection. The terminal application 102 can also access the operation data wirelessly, obtain the operation data based on the time period, and compare the operation data with the corresponding threshold parameters, and then generate an early warning mark and an early warning trend chart. The staff can select the corresponding motor 200 on the terminal application 102 and view the recent operation trend of the motor 200, understand the operation status of the motor 200 through the early warning trend chart, and make a decision to repair the corresponding motor 200. The staff can also receive the early warning information of the motor 200 in real time on the terminal application 102, and quickly go to solve the fault problem of the motor 200 to avoid affecting the operation of the factory.

The device may also include a carrier medium of a terminal application 102 within the motor monitoring system 100, such as a handheld explosion-proof terminal or a smart phone. The monitoring device 101 and the carrier medium of the terminal application 102 are used in conjunction with each other to improve the efficiency of the staff in repairing the motor 200.

[0072] The device provided by the above disclosed embodiment includes the motor monitoring system 100 provided by the above embodiment. The staff can operate the terminal application 102 on the handheld terminal in the device to view the real-time operation data of the motor 200. The operation data of the motor 200 is monitored by the monitoring device 101 set on the motor 200. The monitoring device 101 collects the original operation data of the motor 200 and obtains the operation data of the motor 200 after processing. The monitoring device 101 also stores the operation data for the terminal application 102 to call. The terminal application 102 is connected to the monitoring device 101 by wireless. As long as the staff is connected to the monitoring device 101 wirelessly, they can access the historical operation data of the motor stored in the monitoring device 101. In addition, the terminal application 102 can also generate an early warning mark and an early warning trend chart of the real-time operation data by comparing the real-time operation data with the threshold parameters. The staff can view the early warning mark and timely repair the damaged motor 200.
