At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0048] In an exemplary embodiment, as shown in FIG1 , the present application provides an intelligent grease replenishment system, which includes an operation status monitoring device 2, a grease replenishment device 4, and a controller 6. The operation status monitoring device 2 is used to collect the equipment operation status image and the equipment operation temperature; the grease replenishment device 4 is used to replenish grease to the equipment 300; the controller 6 is connected to the operation status monitoring device 2 and the grease replenishment device 4 respectively, and is used to drive the grease replenishment device 4 to replenish grease to the equipment 300 when it is determined that the operation status of the equipment 300 is abnormal according to the equipment operation status image and the equipment operation temperature.

[0049] Exemplarily, the operation status monitoring device 2 can continuously collect the equipment operation status image and equipment operation temperature, and can accurately capture various detailed performances of the equipment 300 during operation, such as the operating posture of the equipment components, the stability of the connection parts, etc. These images are quickly transmitted to the controller 6 in a digital form. At the same time, the temperature change of the equipment 30 is monitored in real time, and the temperature data is also transmitted to the controller 6. After receiving the equipment operation status image and equipment operation temperature data from the operation status monitoring device 2, the controller 6 analyzes them. For example, for the equipment operation status image, image recognition technology can be used to compare the preset normal equipment operation image model to check whether the equipment components have abnormal signs such as displacement, deformation, and increased wear; and when analyzing the equipment operation temperature, the controller 6 will refer to the set value of the normal operating temperature range of the equipment 300 to determine whether the current temperature exceeds the reasonable range. Once it is determined that the operation status of the equipment 300 is abnormal through a comprehensive analysis of the image and temperature data, the controller 6 will issue a drive instruction to the grease replenishing device 4. After receiving the driving instruction from the controller 6, the grease replenishing device 4 immediately starts its internal power mechanism and conveying pipeline system, then extracts an appropriate amount of grease from the container storing the grease, and accurately delivers the grease to the key lubrication points of the device 300 in abnormal operation through the conveying pipeline. In the process of replenishing grease, the controller 6 can also determine the specific situation of the device 300 according to the standby operation status image, and feed it back to the grease replenishing device 4, so that it can dynamically adjust the replenishment speed and pressure to ensure that the grease can be evenly and fully filled into the parts that need lubrication, so that the friction parts of the device 300 are well lubricated, thereby effectively reducing the friction coefficient, wear and heat generation. After the grease is replenished, the operating state of the device 300 is expected to be improved. The operating state monitoring device 2 will continue to monitor the subsequent operation of the device 300 and feed back the new data to the controller 6 so that the controller 6 can further determine whether the device 300 has resumed normal operation. If it has not yet resumed normal operation, further measures may be taken or an alarm may be issued to notify the maintenance personnel to perform manual intervention and maintenance.

[0050] The above-mentioned intelligent grease replenishment system automatically collects data with the help of the operation status monitoring device, uses image recognition technology and temperature judgment to analyze the equipment status, and accurately determines whether grease needs to be replenished. It not only improves the maintenance effect, avoids the problem of inadequate grease replenishment and shortened equipment life due to visual misjudgment, so that the equipment can be closer to the normal operating life, but also reduces the failure rate of rotating equipment. By timely replenishing grease, it ensures good lubrication of friction parts, reduces wear, heat generation, jamming and other faults, and effectively guarantees the stability and reliability of equipment operation, thereby improving the safety and stability of the entire power system and promoting efficient and stable operation of the power industry.

[0051] In an exemplary embodiment, as shown in FIG2 , the equipment operation status image includes an equipment lubrication status image, and the operation status monitoring device 2 includes a camera 22 and a temperature sensor 24. The camera 22 is electrically connected to the controller 6 for collecting the equipment lubrication status image; the temperature sensor 24 is electrically connected to the controller 6 for collecting the equipment operation temperature; the controller 6 is used to determine that the operation status of the equipment 300 is abnormal when the equipment lubrication status image is inconsistent with the standard lubrication status image and / or the equipment operation temperature is greater than a preset temperature; wherein the standard lubrication status image is an image of the equipment 300 in a normal lubrication status; and the preset temperature is a normal temperature when the equipment 300 is in a normal lubrication status.

[0052] Among them, the standard lubrication state image is a reference image, which represents the appearance of the device 300 in a normal lubrication state. The image records the details of the running posture of each component of the device 300 when properly lubricated, the stability of the connection parts, and the overall running state. For example, in a normal lubrication state, the transmission parts of the device 300 can rotate smoothly, and the gloss and texture of its surface may present a stable state. These details will be recorded in the standard lubrication state image. By comparing the real-time collected device lubrication state image with it, it can be determined whether the current lubrication state of the device 300 is normal. If the device lubrication state image is inconsistent with the standard lubrication state image, it means that there may be a problem with the lubrication of the device 300, such as insufficient grease, uneven grease distribution, or contamination of grease, and it can be inferred that the running state of the device 300 is abnormal. The preset temperature refers to the normal temperature range of the device 300 in a normal lubrication state. When the device 300 is operating normally and well lubricated, due to the effect of grease, the friction coefficient between the device components is maintained at a reasonable level, and the heat generated is also relatively stable. This stable temperature range is the preset temperature. When the device operating temperature collected by the temperature sensor 24 is greater than the preset temperature, it indicates that the operating state of the device 300 may be abnormal. This may be because insufficient grease causes increased friction between device components, thereby generating excessive heat, or some components of the device 300 have malfunctioned, such as overload operation, severe component wear, etc., resulting in increased temperature. By comparing the device operating temperature with the preset temperature, the abnormality of the operating state of the device 300 can be discovered in time so that corresponding measures can be taken, such as replenishing grease or repairing the device 300.

[0053] Exemplarily, the camera 22 and the temperature sensor 24 are electrically connected to the controller 6. The camera 22 continuously captures the image of the lubrication status of the equipment and transmits it to the controller 6, such as capturing the image information such as the coverage and distribution of grease at the transmission gear of the equipment 300. The temperature sensor 24 closely monitors the temperature data of the equipment 300 during operation and feeds it back to the controller 6. When there is a difference between the collected image of the lubrication status of the equipment and the pre-stored standard lubrication status image, such as the grease is missing, unevenly distributed or abnormal in color, or when the equipment operating temperature transmitted by the temperature sensor 24 exceeds the preset temperature, such as the motor is running at a temperature higher than the normal temperature limit under normal lubrication conditions due to poor lubrication, the controller 6 will determine that the operating state of the equipment 300 is abnormal, and then trigger the subsequent corresponding response mechanism such as driving the grease replenishing device 4 to work, so as to ensure the normal and stable operation of the equipment 300.

[0054] In this embodiment, by accurately monitoring the equipment through cameras and temperature sensors, and using the standard lubrication status image and preset temperature as the basis for judgment, it is possible to accurately and timely determine whether the equipment operating status is abnormal. This effectively solves the problem that traditional manual maintenance is difficult to detect poor equipment lubrication, greatly improves the accuracy and timeliness of equipment lubrication status monitoring, reduces equipment wear and failure caused by insufficient or abnormal lubrication, extends equipment service life, reduces equipment failure rate, and ensures stable operation of equipment in the power system. At the same time, the automated monitoring and judgment mechanism also improves overall maintenance efficiency, reduces manual inspection costs and manpower investment, and improves the reliability and safety of power system operation.

[0055] In an exemplary embodiment, the controller 6 is used to determine a target grease replenishment amount based on the equipment lubrication status image and the standard lubrication status image when it is determined that the operating state of the equipment 300 is abnormal, and drive the grease replenishing device 4 to replenish the equipment 300 with the target grease replenishment amount of grease.

[0056] The target amount of grease replenishment refers to the specific mass of grease that needs to be replenished, which is determined based on the difference between the current lubrication state image of the device 300 and the standard lubrication state image when the controller 6 determines that the operating state of the device 300 is abnormal. For example, if the device lubrication state image shows that the grease coverage area on a key transmission component of the device 300 is only half of the grease coverage area of ​​the component in the standard lubrication state image, and the thickness of the grease is also obviously insufficient, then the controller 6 will calculate how much grease needs to be replenished to restore the component to the standard lubrication state through a pre-set algorithm or model. The mass calculated is the target amount of grease replenishment. This parameter is determined to accurately replenish grease to the device 300 to avoid over- or under-replenishment. If the replenishment amount is too much, it may cause problems such as grease waste and increased operating resistance of the device 300; if the replenishment amount is too little, the lubrication state of the device 300 cannot be effectively improved, and the abnormal operating state of the device 300 may continue, or even further damage to the device 300 due to insufficient lubrication.

[0057] Exemplarily, when the controller 6 determines that the operating state of the device 300 is abnormal based on the inconsistency between the device lubrication state image and the standard lubrication state image, or the device operating temperature is greater than the preset temperature, it starts to analyze the device lubrication state image. For example, it is found that the grease at the bearing of the device 300 is seriously missing in the image, and the remaining grease is extremely unevenly distributed, which is significantly different from the uniform and sufficient grease condition that the bearing should have in the standard lubrication state image. According to this degree of difference, the controller 6 uses the built-in calculation model to comprehensively consider factors such as the size, rotation speed, and operating load of the bearing, and accurately calculates the amount of grease required to restore the bearing to a normal lubrication state, which is the target grease replenishment amount. Subsequently, the controller 6 drives the grease replenishment device 4 to accurately deliver an appropriate amount of grease to the bearing part of the device 300 according to the calculated target grease replenishment amount, so that the lubrication state of the device 300 is improved, and then normal and stable operation is restored.

[0058] In this embodiment, the target amount of grease replenishment is determined based on the comparison between the equipment lubrication status image and the standard lubrication status image, thereby achieving accurate grease replenishment. This avoids the problem of adding too much or too little grease due to the lack of accurate judgment in traditional manual replenishment, prevents the waste of resources, increased equipment operation resistance and even the risk of failure due to excessive addition, and reduces the situation where the equipment is in a poor lubrication state due to insufficient addition, effectively reducing equipment wear, reducing the failure rate caused by lubrication problems, and extending the service life of the equipment. At the same time, it improves the efficiency and intelligence level of equipment maintenance, ensures the stable and efficient operation of related equipment in the power system, and reduces operation and maintenance costs and manpower investment.

[0059] In an exemplary embodiment, as shown in Fig. 2, the grease replenishing device 4 includes an oil tank 42 and an oil injection pump 44. The oil tank 42 is used to store grease; the oil injection pump 44 is electrically connected to the controller 6, the oil inlet pipeline of the oil injection pump 44 is connected to the oil delivery pipeline of the oil tank 42, and the oil delivery pipeline of the oil injection pump 44 is connected to the oil inlet pipeline of the device 300; the controller 6 is used to drive the oil injection pump 44 to deliver the target amount of grease to the oil inlet pipeline of the device 300 when it is determined that the operating state of the device 300 is abnormal.

[0060] Exemplarily, the camera 22 and the temperature sensor 24 of the operation status monitoring device 2 collect the lubrication status image and the operation temperature of the device 300 in real time and transmit them to the controller 6. Once the controller 6 determines that the operation status of the device 300 is abnormal based on the comparison between the lubrication status image of the device and the standard lubrication status image and the comparison between the operation temperature of the device and the preset temperature, it will determine the target amount of grease replenishment based on the difference in the lubrication status image of the device. Subsequently, the controller 6 sends a driving instruction to the oil filling pump 44, and the oil filling pump 44 starts. The oil filling pump 44 extracts a corresponding amount of grease from the oil delivery pipeline of the oil storage tank 42 through its oil inlet pipeline, and then accurately delivers the target amount of grease replenishment to the oil inlet pipeline of the device 300 through its own oil delivery pipeline, so that the grease can smoothly enter the part of the device 300 that needs to be lubricated, thereby improving the lubrication condition of the device 300, and it is expected to restore the normal operation of the device 300. The whole process efficiently and accurately realizes the automatic replenishment of the grease of the device 300.

[0061] In this embodiment, the grease replenishing device is designed to include an oil storage tank and an oil injection pump, and the operation of the oil injection pump is accurately controlled by the controller, so that the grease replenishment is automated and accurate. Compared with the traditional manual grease replenishment, it not only greatly reduces the manpower input and labor intensity, but also can accurately replenish the target amount of grease according to the actual needs of the equipment, effectively avoiding the waste of grease and equipment operation failure caused by improper replenishment.

[0062] In an exemplary embodiment, as shown in FIG2 , the grease replenishing device 4 further includes a timing device 46. The timing device 46 is electrically connected to the controller 6 and is used to calculate the cumulative time of the oil injection pump 44 delivering grease to the oil inlet pipeline of the device 300; the controller 6 is used to control the oil injection pump 44 to stop delivering grease to the oil inlet pipeline of the device 300 when the cumulative time is greater than a preset time; wherein the preset time is in direct proportion to the target amount of grease replenishment.

[0063] The preset time refers to a time threshold value set in advance, which is in direct proportion to the target amount of grease replenishment. When the target amount of grease replenishment required by the device 300 is determined, the time threshold value can be determined based on the direct proportion between the two. For example, if the target amount of grease replenishment is large, it takes a long time to deliver such a large amount of grease to the oil inlet pipeline of the device 300 according to the fixed flow rate of the oil injection pump 44, and the corresponding preset time will be longer; conversely, if the target amount of grease replenishment is small, the time required for the oil injection pump 44 to deliver is short, and the preset time is also short.

[0064] Exemplarily, after the controller 6 determines that the operating state of the device 300 is abnormal and determines the target amount of grease to be replenished, the oil injection pump 44 starts to work to deliver grease to the oil inlet pipeline of the device 300, and the timing device 46 starts synchronously. For example, if the target amount of grease to be replenished is calculated to be large, the corresponding preset time is 10 minutes according to its positive proportional relationship with the preset time. During the operation of the oil injection pump 44, the timing device 46 continues to accumulate time. When the time reaches 8 minutes, the oil injection pump 44 is still delivering grease at a predetermined flow rate. As time goes by, once the accumulated time exceeds the preset time of 10 minutes, the controller 6 will immediately control the oil injection pump 44 to stop working, thereby ensuring that the amount of grease delivered is close to the target replenishment amount, and neither insufficient grease replenishment due to too short a time nor excessive grease injection into the device 300 due to too long a time, thereby ensuring that the device 300 can resume normal operation and maintain stable operation with an appropriate amount of grease.

[0065] In this embodiment, by setting a preset time that is directly proportional to the target grease replenishment amount, and using a timing device to work in conjunction with a controller, precise time control of the grease replenishment process is achieved, effectively avoiding the problem of excessive deviation in the grease replenishment amount due to uncontrolled working time of the oil injection pump, ensuring that the amount of grease replenished each time can accurately match the actual needs of the equipment, greatly improving the accuracy and stability of grease replenishment.

[0066] In an exemplary embodiment, as shown in FIG2 , the operation status monitoring device 2 includes a weight sensor 26. The weight sensor 26 is used to monitor the oil quantity change in the oil storage tank 42; the controller 6 is used to determine the oil injection amount according to the oil quantity change, and when the oil injection amount is greater than the target grease replenishment amount, control the oil injection pump 44 to stop delivering grease to the oil inlet pipeline of the device 300.

[0067] For example, during the grease replenishment process, if the timing device 46 fails, the weight sensor 26 can continuously monitor the change in the oil volume in the oil tank 42. Assuming that the target grease replenishment amount determined according to the state of the device 300 is 500 grams, after the oil filling pump 44 is started, the weight sensor 26 feeds back the reduction data of the oil volume in the oil tank 42 in real time. As the oil filling pump 44 continues to work, if the calculated oil filling amount corresponding to the reduced oil volume reaches 500 grams, even if there is no time limit of the timing device 46, the controller 6 will immediately control the oil filling pump 44 to stop delivering grease to the oil inlet pipeline of the device 300 according to the data of the weight sensor 26, thereby effectively preventing the excessive injection of grease that may be caused by the failure of the timing device 46, ensuring that the grease replenishment amount is as accurate as possible to the target replenishment amount, and ensuring the normal lubrication and stable operation of the device 300.

[0068] In this embodiment, in the special case of failure of the timing device, the introduction of the weight sensor provides a reliable redundant protection mechanism. It can accurately monitor the changes in the oil volume in the oil storage tank, thereby accurately determining the amount of oil to be injected, and effectively avoiding the problem of excessive grease replenishment that may be caused by the failure of time control. This not only ensures that the equipment can always obtain the amount of grease that matches the actual demand, maintains the good lubrication state of the equipment, reduces the wear, failure and energy loss caused by improper lubrication, and extends the service life of the equipment, but also greatly improves the stability and reliability of the entire intelligent grease replenishment system, reduces the risk of abnormal equipment operation due to the failure of a single monitoring or control means, ensures the continuous, stable and efficient operation of related equipment in the power system, and reduces operation and maintenance costs and downtime.

[0069] In an exemplary embodiment, the camera 22 is an angle-adjustable high-definition camera 22, which is used to capture equipment lubrication status images according to target parameters; the target parameters include at least one of a target capture frame rate, a target capture resolution, a target capture format, and a target capture angle.

[0070] Exemplarily, when the system starts running, the controller 6 will comprehensively set the target parameters based on the specific type of the device 300, the operating conditions, and the past data. For example, for a device 300 that runs at high speed and has high lubrication requirements, a higher target acquisition frame rate, such as 30 frames per second, is set to clearly capture the rapid changes in the lubrication state; a suitable target acquisition resolution, such as 1920×1080, is determined so that the image can accurately present the details of the lubrication parts of the device 300; a commonly used image acquisition format, such as JPEG, is selected to facilitate data transmission and storage; and a specific target acquisition angle is set according to the structural layout of the device 300, such as a specific angle for the side of a bearing. After receiving these target parameters, the high-definition camera 22 with adjustable angles will automatically adjust its own shooting frame rate, resolution, format, and shooting angle, and then start to collect images of the lubrication state of the device, and transmit the collected image data to the controller 6 in real time, providing a clear, accurate, and satisfactory image basis for subsequent operations such as judging the lubrication state of the device 300 and determining whether grease needs to be added.

[0071] In this embodiment, by using an adjustable-angle high-definition camera and collecting images of the lubrication status of the equipment according to target parameters, highly flexible and accurate image acquisition can be achieved. Different target acquisition frame rates can adapt to the effective capture of the lubrication status of the equipment at different operating speeds, avoiding omission or redundancy of image information; appropriate target acquisition resolution helps to accurately understand subtle changes and abnormalities in the lubrication parts of the equipment and improve the accuracy of fault prediction; specific target acquisition formats facilitate rapid data processing, transmission and storage, and optimize the system data flow efficiency; and adjustable target acquisition angles can fully cover the key lubrication points of the equipment to ensure that there are no blind spots for monitoring.

[0072] In an exemplary embodiment, when the grease replenishing device 4 includes an oil storage tank 42 and a weight sensor 26, the operating status monitoring device 2 further includes a display screen 28. The display screen 28 is electrically connected to the controller 6 and is used to display an image of the equipment operating status, the equipment operating temperature, and the oil volume change of the oil storage tank 42.

[0073] In this embodiment, by setting a display screen connected to the controller, the equipment operating status image, operating temperature and oil volume change in the oil storage tank can be intuitively displayed. This allows operation and maintenance personnel to easily obtain key information, timely know the lubrication status and operating status of the equipment, and quickly determine whether there is an abnormality. When a problem occurs with the equipment, it helps to quickly locate the fault point, such as determining whether it is poor lubrication or other operating failures based on the image and temperature changes, and at the same time understand whether the grease replenishment is normal based on the oil volume changes. It not only improves the operation and maintenance efficiency and reduces the time and energy investment in manual inspections, but also enhances the monitorability and transparency of the system, making it convenient for the operation and maintenance team to carry out overall equipment management and maintenance planning, ensuring the stable and reliable operation of equipment in the power system, and reducing the risk of equipment damage and the probability of power supply interruption due to untimely information acquisition.

[0074] In an exemplary embodiment, the system further includes an alarm device 8. The alarm device 8 is electrically connected to the controller 6; the controller 6 is used to control the alarm device 8 to output alarm information when determining that the operating state of the device 300 is abnormal.

[0075] In this embodiment, when the controller 6 determines that the operating state of the device 300 is abnormal, it can quickly control the alarm device 8 to output an alarm message.
