Description

Technical Field

[0001] This utility model relates to a device status monitoring and intelligent lubrication system based on multi-point, distributed scenarios. Background Technology

[0002] In the field of automatic dry lubrication of equipment, some equipment has many and scattered lubrication points (referred to as lubrication points), such as mines, medium and large-scale production lines, and construction machinery. These equipment has numerous and dispersed lubrication points, and the distance between multiple pieces of equipment is also considerable. Traditional centralized lubrication systems cannot meet the needs, mainly due to the following problems: 1. The centralized lubrication system is installed on the equipment, but its working status is unknown. Even if maintenance personnel arrive at the equipment, they can only see if the centralized lubrication system is working, but the effectiveness of its operation is unknown. That is, whether the amount of grease added to the friction pairs of the equipment is appropriate cannot be known, and good lubrication of the equipment cannot be ensured. Maintenance personnel still need to frequently check the equipment status; 2. Traditional centralized lubrication systems rely on the lubrication requirements of each friction pair of the equipment at the time of installation. The program-set lubrication strategy, such as adding 1ml of grease to lubrication point 1 every hour, adding 3ml of grease to lubrication point 2, etc., is not effective because the traditional centralized lubrication system cannot detect changes in the equipment's operating status. Therefore, it cannot adjust the lubrication strategy accordingly, and maintenance personnel cannot promptly detect these changes or manually adjust the centralized lubrication system's strategy, leading to poor lubrication. Furthermore, because the lubrication points are dispersed, the corresponding lubrication systems are also scattered. To check the lubrication system's status and replenish the required grease promptly, maintenance personnel must visit each of the dispersed lubrication systems sequentially, resulting in a significant workload. This has led many users to abandon the lubrication system altogether and opt for traditional manual lubrication. Utility Model Content

[0003] To address the above issues, this utility model provides a device status monitoring and intelligent lubrication system for multi-point, dispersed scenarios. This system allows real-time viewing of the device's operating and lubrication status via a terminal. Based on changes in the device's operating status, it adaptively adjusts or remotely and manually adjusts the lubrication strategy of the lubrication system. It can also promptly detect device malfunctions and abnormalities in the lubrication system, enabling timely investigation of fault locations, checks of the lubrication system status at locations reporting abnormalities, and replenishment of grease. The system significantly improves automation and greatly reduces manual labor intensity and maintenance costs.

[0004] The technical solution of this utility model is as follows: A device status monitoring and intelligent lubrication system based on multi-point, dispersed scenarios includes:

[0005] The lubrication module is used to pressurize and pump grease to various lubrication points. It includes a centralized lubrication system installed between various dispersed devices. The centralized lubrication system comprises a main control cabinet, a multi-point lubrication pump, and an intelligent oil distribution tank. The multi-point lubrication pump has multiple grease outlets corresponding to each dispersed device. Each grease outlet is connected to an intelligent oil distribution tank via a pipeline. The intelligent oil distribution tank is used to add grease to the lubrication points of a device that are relatively close together, either through pipelines or a distributor. The main control cabinet includes a wireless communication module. The multi-point lubrication pump has an oil level detection module that transmits oil level data to the main control cabinet. The main control cabinet is electrically connected to the multi-point lubrication pump to control its operation. The multi-point lubrication pump delivers grease at a pressure of no less than 40 MPa to meet the grease supply needs of the dispersed devices located at greater distances. The intelligent oil distribution tank includes an intelligent controller and multiple solenoid valves controlled by the controller. Each solenoid valve controls the on / off state of one lubrication oil circuit. The intelligent controller and the main control cabinet exchange data.

[0006] The data acquisition module has multiple sets, each of which is arranged on the dispersed equipment. Each set includes a vibration sensor, a temperature sensor, a speed sensor, and a data acquisition unit that collects the signals from the three sensors. The three sensors are used to collect the vibration, temperature, and speed values ​​of the equipment, respectively.

[0007] The client terminal includes display hardware and a device management platform. The device management platform includes a wireless communication module and a data processing module. The main control cabinet interacts with the device management platform through the wireless communication module.

[0008] Each data acquisition module transmits data to the device management platform via a wireless communication module, or transmits data to the main control cabinet via a wireless communication module and / or a wired connection.

[0009] During operation, the customer terminal analyzes the vibration, temperature, and speed values ​​fed back by the three sensors through the data processing module to determine the lubrication status and equipment operating status, including the equipment fault type and corresponding location information, the centralized lubrication system abnormality type and corresponding location information, and then issues a fault alarm or generates a new lubrication strategy instruction to send to the main control cabinet to control the lubrication module to execute the corresponding lubrication strategy.

[0010] Furthermore, the system includes a grease replenishment module, which comprises a grease storage tank, an electric grease replenishment pump, and an oil pipe connector assembly. The electric grease replenishment pump includes a grease replenishment controller, which is connected to the main control cabinet. When the oil level detection module of the multi-point lubrication pump detects that the oil level has reached the minimum set value, the equipment management platform sends a grease replenishment command to the main control cabinet. The main control cabinet then sends a grease replenishment start command to the grease replenishment controller, controlling the electric grease replenishment pump to operate and pressurize the grease in the grease storage tank to the oil tank of the lubrication module. When the oil level detection module detects that the oil level has reached the maximum set value, the equipment management platform sends a grease replenishment stop command to the main control cabinet. The main control cabinet then sends a grease replenishment stop command to the grease replenishment controller, controlling the electric grease replenishment pump to stop operating.

[0011] Furthermore, the data acquisition module is connected to the main control cabinet via a 485 bus, CAN bus, or Ethernet cable.

[0012] Furthermore, the vibration sensor is a uniaxial vibration acceleration sensor.

[0013] Furthermore, the vibration sensor and temperature sensor adopt an integrated temperature and vibration sensor.

[0014] Furthermore, the speed sensor is a Hall effect speed sensor.

[0015] Furthermore, the data transmitted from the main control cabinet to the equipment management platform includes the grease supply start time, grease supply volume, grease pressure, solenoid valve start and stop time, and grease level alarm information when the grease level reaches the set maximum and minimum values.

[0016] Furthermore, the intelligent controller transmits data to the main control cabinet via an RS-485 fieldbus.

[0017] The beneficial effects of this utility model are as follows: The equipment status monitoring and intelligent lubrication system based on multi-point, dispersed scenarios is mainly applicable to scenarios such as mines, medium and large-scale production lines, and construction machinery where there are many dispersed equipment points, and each equipment has numerous and dispersed lubrication points. The lubrication module uses a multi-point lubrication pump with a pumping pressure of no less than 40 MPa, which includes multiple grease outlets. Each outlet is connected to an intelligent grease distribution tank via an oil pipe. The entire system is centrally controlled by a main control cabinet. The intelligent grease distributors corresponding to each dispersed device directly transmit data to the main control cabinet, supporting long-distance grease delivery between devices up to tens of meters apart. Simultaneously, the equipment is divided into zones, with each zone using a data acquisition unit to collect data such as vibration, temperature, and rotational speed. Multiple data acquisition units transmit the data to the main control cabinet or directly to the equipment management platform. This layout eliminates the need for additional data acquisition units with numerous channels and interfaces, requiring only multiple ordinary, inexpensive data acquisition units. Furthermore, due to the large distances between devices, this method also reduces wiring costs. The total length of the cable is reduced, achieving cost reduction. Furthermore, because the lubrication module and data acquisition module can transmit real-time data such as grease supply start time, grease supply volume, grease pressure, solenoid valve start / stop time, grease level alarm information when the grease level reaches the set maximum and minimum values, equipment vibration data, temperature data, and rotation speed data to the client's equipment management platform, users can view the equipment's operating status and lubrication status in real-time via mobile terminals. They can also promptly be aware of equipment malfunctions and lubrication system anomalies, allowing for timely troubleshooting at reported fault locations, checking the lubrication system status at reported anomalies, and replenishing grease. Since the equipment management platform can compare and analyze the collected signals with data from the database to calculate the type of equipment operating status, and transmit data to the lubrication controller via the platform, it can adaptively adjust or remotely manually adjust the lubrication strategy of the lubrication system via the terminal. This significantly improves automation and greatly reduces manual labor intensity and maintenance costs. Attached Figure Description

[0025] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0026] Example 1 of the present invention: Equipment status monitoring and intelligent lubrication system based on multi-point distributed scenarios: Figure 1 As shown, the equipment status monitoring and intelligent lubrication system based on multi-point and distributed scenarios includes a lubrication module 1, a grease replenishment module 4, a data acquisition module 2, and an equipment management platform 3.

[0027] The lubrication module 1 is used to pressurize and pump grease to various lubrication points. It includes a centralized lubrication system installed between the dispersed equipment. The centralized lubrication system includes a main control cabinet 11, a multi-point lubrication pump 12, and an intelligent grease distribution tank 13. The multi-point lubrication pump 12 has multiple grease outlets corresponding to the dispersed equipment, and each grease outlet is connected to an intelligent grease distribution tank 13 via a pipeline. The intelligent grease distribution tank 13 is used to add grease to the lubrication points of a particular equipment that are relatively close together, either through pipelines or a distributor. The main control cabinet 11 includes a... The multi-point lubrication pump 12 is equipped with an oil level detection module, which transmits oil level data to the main control cabinet 11. The main control cabinet 11 is electrically connected to the multi-point lubrication pump 12 to control its operation. The multi-point lubrication pump 12 delivers grease at a pressure of not less than 40 MPa to meet the grease supply needs of various distributed devices located at greater distances. The intelligent oil distribution tank 13 includes an intelligent controller 131 and multiple solenoid valves 132 controlled by it. Each solenoid valve 132 controls the on / off state of one lubrication oil circuit. The intelligent controller 131 and the main control cabinet 11 exchange data. For example, a mine needs to lubricate its equipment, which consists of approximately 10 pieces of equipment, spaced at least 5 meters apart. Each piece of equipment has at least 10 lubrication points. A large-displacement multi-point lubrication pump 12 with a tank capacity of 100L or more and a pumping pressure of 40MPa or more is used. This multi-point lubrication pump 12 has at least 10 grease outlets, each connected to a smart oil distribution tank 13 via a main oil pipe. The smart oil distribution tank 13 contains four solenoid valves 132, each controlling one oil circuit. A progressive distributor can be connected to solenoid valves 1-2 to achieve grease distribution to more than 10 lubrication points. A certain number of vibration sensors 21, temperature sensors 22, and speed sensors 23 are appropriately installed near the moving parts and lubrication points on each piece of equipment. Each sensor on each piece of equipment is monitored by a data acquisition unit 24, which then transmits the data to the equipment management platform 3 via a wireless communication module.

The electric grease replenishment pump 42 includes a grease replenishment controller, which is connected to the main control cabinet 11. When the oil level detection module of the multi-point lubrication pump 12 detects that the oil level has reached the minimum set value, the equipment management platform 3 sends a grease replenishment command to the main control cabinet 11. The main control cabinet 11 sends a grease replenishment start command to the grease replenishment controller, controlling the electric grease replenishment pump 42 to run, so as to pressurize and pump the grease in the grease storage tank 41 to the oil tank of the lubrication module 1. When the oil level detection module detects that the oil level has reached the maximum set value, the equipment management platform 3 sends a grease replenishment stop command to the main control cabinet 11. The main control cabinet 11 sends a grease replenishment stop command to the grease replenishment controller, controlling the electric grease replenishment pump 42 to stop running.

[0029] The data acquisition module 2 consists of multiple sets, each arranged on a distributed device. Each set includes a vibration sensor 21, a temperature sensor 22, a speed sensor 23, and a data acquisition unit 24 for collecting signals from the three sensors. The three sensors are used to collect vibration, temperature, and speed values ​​from the device, respectively. They are fixedly installed at appropriate locations on the device to be lubricated, primarily detecting vibration, temperature, and speed data at the lubrication points. The vibration sensor 21 is a single-axis vibration acceleration sensor, or the vibration sensor 21 and temperature sensor 22 can be combined into a single temperature and vibration sensor. The speed sensor 23 is a Hall effect speed sensor.

[0030] The client terminal includes display hardware and device management platform 3. Device management platform 3 includes a wireless communication module and a data processing module. The display hardware can be various smart terminals such as mobile phones, tablets, laptops, desktop computers, in-vehicle computers, and instrument monitoring devices. Device management platform 3 is a software platform that runs on the corresponding smart terminal in the form of a web page or APP. The main control cabinet 11 interacts with device management platform 3 through the wireless communication module; the data acquisition units 24 of each group of data acquisition modules transmit data to device management platform 3 through the wireless communication module, or transmit data to the main control cabinet 11 through the wireless communication module and / or wired means. The system architecture corresponding to device management platform 332 is as follows: Figure 3 As shown. The equipment management platform 3 includes a wireless communication module and a data processing module. The equipment management platform 3 uses a big data platform and analysis and diagnostic algorithms to determine whether each lubrication point needs to be lubricated, and can issue lubrication commands to the corresponding lubrication system according to the selection, so as to realize intelligent lubrication of each lubrication point.

[0031] During operation, the customer terminal analyzes the vibration, temperature, and speed values ​​fed back by the three sensors through the data processing module to determine the lubrication status and equipment operating status, including the equipment fault type and corresponding location information, the centralized lubrication system abnormality type and corresponding location information, and then issues a fault alarm or generates a new lubrication strategy instruction to send to the main control cabinet 11 to control the lubrication module 1 to execute the corresponding lubrication strategy.

[0032] In this embodiment, the data acquisition unit 24 has one channel each for vibration, temperature, and rotational speed, and reserves 4G / RS485 / RJ45 communication interfaces. The vibration sensor 21 is a single-axis vibration acceleration sensor with analog output. The temperature sensor 22 is a PT100 or transmitter with analog output.

[0033] In this embodiment, as Figure 1 As shown, each data acquisition module 2 transmits data to the device management platform 3 via a wireless communication module; in embodiment 2, as... Figure 2As shown, the data acquisition module 2 transmits data to the main control cabinet 11 via a wired connection. The wired connection between the data acquisition module 2 and the main control cabinet 11 is via a 485 bus, a CAN bus, or an Ethernet cable. In other embodiments, the data acquisition module 2 and the main control cabinet 11 can also transmit data via a wireless communication module.

[0034] This utility model's equipment status monitoring and intelligent lubrication system based on multi-point, dispersed scenarios is mainly applicable to scenarios such as mines, medium and large-scale production lines, and construction machinery where there are many dispersed equipment points, and each equipment has many dispersed lubrication points. The lubrication module 1 uses a multi-point lubrication pump 12 with a pumping pressure of not less than 40 MPa, which includes multiple grease outlets. Each outlet is connected to an intelligent grease distribution tank 13 via an oil pipe. The entire system is centrally controlled by the main control cabinet 11. The intelligent grease distributors corresponding to each dispersed device directly transmit data to the main control cabinet 11, which can support long-distance grease delivery between devices with a distance of tens of meters. At the same time, the equipment is divided into areas, and each area's equipment uses a data acquisition device 24 to collect data such as vibration, temperature, and rotation speed. Multiple data acquisition devices 24 transmit the data to the main control cabinet 11 or directly to the equipment management platform 3. This layout method requires only multiple ordinary and inexpensive data acquisition devices 24 because the data acquisition devices 24 do not need to add too many channel interfaces. Since the distance between the devices is relatively far, this method can also reduce wiring. The total length of the cable is reduced, achieving cost reduction. In addition, since the lubrication module 1 and the data acquisition module 2 can transmit the grease supply start time, grease supply amount, grease pressure, solenoid valve 132 start and stop time, grease level alarm information when the grease level reaches the set maximum and minimum values, equipment vibration data, temperature data, and rotation speed data to the client's equipment management platform 3 in real time, users can view the equipment's operating status and lubrication status through mobile terminals in real time, and can promptly know about equipment faults and abnormalities in the lubrication system, so as to promptly go to the fault location to troubleshoot the fault, promptly go to the lubrication system location to check the lubrication system status, and replenish grease, etc. Since the equipment management platform 3 can compare and analyze the various signals collected with the database to calculate the type of equipment operating status, and transmit data to the lubrication controller through the equipment management platform 3, the lubrication strategy of the lubrication system can be adaptively adjusted or remotely and manually adjusted through the terminal, the degree of automation is significantly improved, greatly reducing the intensity of manual labor and maintenance costs.
