Description

Technical Field

[0001] The present invention relates to a device status monitoring and intelligent lubrication system based on a point multi-dispersion scenario. Background Art

[0002] In the field of grease automatic lubrication of equipment, some equipment has a large number of parts that need to be filled with grease (referred to as lubrication points for short) and they are relatively dispersed. For example, in mines, medium and large production lines, construction machinery, etc., the lubrication points on the equipment are numerous and dispersed, and the distances between multiple equipment are also relatively far. The traditional centralized lubrication system cannot meet the requirements, and there are mainly the following problems: 1. The centralized lubrication system is installed on the equipment, and its working status cannot be known. Even when the maintenance personnel arrive at the equipment, at most they can see whether the centralized lubrication system is working, but the effectiveness of the lubrication system's work cannot be known, that is, it cannot be known whether the amount of grease filled in the friction pairs of the equipment is appropriate, and it is impossible to ensure good lubrication of the equipment. The maintenance personnel still need to frequently check the equipment status; 2. The traditional centralized lubrication system is based on the lubrication strategy set by the program according to the lubrication requirements of each friction pair of the equipment during installation. For example, 1 ml of grease is filled into lubrication point No. 1 every hour, 3 ml of grease is filled into lubrication point No. 2... However, when the working status of the equipment changes, the traditional centralized lubrication system cannot sense the change in the working status of the equipment, so it cannot adapt to adjust the lubrication strategy, and the maintenance personnel cannot timely know the change in the working status of the equipment either. The maintenance personnel cannot manually adjust the lubrication strategy of the centralized lubrication system either, which will also lead to poor lubrication of the equipment; 3. Since the lubrication points of the equipment are relatively dispersed, the corresponding lubrication systems are also relatively dispersed. In order to timely check the status of the lubrication system and timely replenish the required grease, the maintenance personnel need to arrive at each dispersed lubrication system in turn every time they perform maintenance, and the workload is very large. This also causes many users to abandon the lubrication system and adopt traditional manual lubrication. Summary of the Invention

[0003] Based on the above problems, the present invention provides a device status monitoring and intelligent lubrication system based on a point multi-dispersion scenario. This system can view the operating status and lubrication status of the equipment in real time through a terminal. According to the change in the operating status of the equipment, it can adaptively adjust or remotely manually adjust the lubrication strategy of the lubrication system through the terminal, and can timely know the equipment failure situation and the abnormal situation of the lubrication system, so as to timely go to the fault point to check the fault, timely go to the lubrication system reporting the abnormality to check the status of the lubrication system and replenish the grease, etc. The degree of automation is significantly improved, and the manual labor intensity and maintenance cost are greatly reduced.

[0004] The technical solution of the present invention is as follows: A device status monitoring and intelligent lubrication system based on a point multi-dispersion scenario includes: The lubrication module is used to pressurize the grease and pump it to each lubrication point, including a centralized lubrication system installed between the dispersed equipment. The centralized lubrication system includes a main control cabinet, a multi-point lubrication pump and an intelligent oil distribution tank. The multi-point lubrication pump includes multiple grease outlets to correspond to the dispersed equipment respectively. Each grease outlet is connected to an intelligent oil distribution tank through a pipeline. The intelligent oil distribution tank is used to add grease to various lubrication points of a certain equipment that are close to each other through a pipeline or a distributor; the main control cabinet includes a wireless communication module, and the multi-point lubrication pump is provided with an oil level detection module. The oil level detection module transmits oil level data to the main control cabinet. The main control cabinet is electrically connected to the multi-point lubrication pump to control the operation of the multi-point lubrication pump; the multi-point lubrication pump has a pumping pressure of no less than 40Mpa for grease to meet the distant grease supply needs of the dispersed equipment; the intelligent oil distribution tank includes an intelligent controller and multiple solenoid valves controlled by it. Each solenoid valve controls the on-off of a lubrication oil circuit, and the intelligent controller and the main control cabinet transmit data to each other; The data acquisition module has multiple groups, which are arranged one by one on the dispersed devices. Each group includes a vibration sensor, a temperature sensor, a speed sensor and a data collector for collecting the signals of the three sensors. The three sensors are used to collect the vibration, temperature and speed values of the equipment respectively. 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 exchanges data with the device management platform through the wireless communication module. The data collector of each group of data acquisition modules transmits data to the equipment management platform through the wireless communication module, or transmits data to the main control cabinet through the wireless communication module and / or wired mode; During operation, the customer terminal can obtain the lubrication status and equipment operation status based on the vibration, temperature and speed values fed back by the three sensors after analysis by the data processing module, including the equipment fault type and corresponding location information, the centralized lubrication system abnormality type and corresponding location information, and then issue a fault alarm or form a new lubrication strategy instruction and send it to the main control cabinet to control the lubrication module to execute the corresponding lubrication strategy.

[0005] Furthermore, it includes a grease replenishing module, which includes a grease storage barrel, an electric grease replenishing pump and an oil pipe joint assembly. The electric grease replenishing pump includes a grease replenishing 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 transmits a grease replenishing instruction to the main control cabinet, and the main control cabinet transmits a grease replenishing start instruction to the grease replenishing controller to control the operation of the electric grease replenishing pump to pressure-pump the grease in the grease storage barrel into 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 transmits a grease replenishing stop instruction to the main control cabinet, and the main control cabinet transmits a grease replenishing stop instruction to the grease replenishing controller to control the electric grease replenishing pump to stop running.

[0006] Furthermore, the wired connection method between the data acquisition module and the main control cabinet is the 485 bus, or the can bus, or the Ethernet cable.

[0007] Furthermore, the vibration sensor is a single-axis vibration acceleration sensor.

[0008] Furthermore, the vibration sensor and the temperature sensor adopt a temperature-vibration integrated sensor.

[0009] Furthermore, the rotational speed sensor is a Hall rotational speed sensor.

[0010] Furthermore, the data transmitted by the main control cabinet to the equipment management platform includes the starting time of grease supply, the grease supply amount, the pressure of the lubricating grease, the starting and stopping time of the solenoid valve, and the liquid level alarm information when the liquid level of the lubricating grease reaches the set maximum and minimum values.

[0011] Furthermore, the intelligent controller transmits data to the main control cabinet through the RS-485 field bus.

[0012] Advantages of the present invention: A device status monitoring and intelligent lubrication system based on a multi-point dispersion scenario of the present invention is mainly applicable to scenarios where there are many and scattered devices such as mines, medium and large production lines, and construction machinery, and there are many and scattered lubrication points on each device. The lubrication module uses a multi-point lubrication pump with a pumping pressure not less than 40 Mpa, which includes a plurality of grease outlets. Each outlet is equipped with an intelligent oil distribution tank through an oil pipe. The whole is centrally controlled by a main control cabinet. The intelligent oil distributors corresponding to each scattered device directly transmit data to the main control cabinet, which can support long-distance grease transportation with a distance of up to dozens of meters between each device; at the same time, the devices are divided into regions, and the devices in each region use a data collector to collect data such as vibration, temperature, and rotation speed. Multiple data collectors transmit the data to the main control cabinet or directly to the device management platform. Since this layout method does not require the data collector to add too many channel interfaces, only multiple ordinary and low-cost data collectors are needed. Because the distance between each device is relatively far, this method can also reduce the total length of the cables, achieving the effect of cost reduction; in addition, because the lubrication module and the data collection module can transmit the starting time of grease supply, the grease supply volume, the pressure of the grease, the starting and stopping time of the solenoid valve, the liquid level alarm information when the liquid level of the grease reaches the set maximum and minimum values, the vibration data, temperature data, and rotation speed data of the device, etc. to the device management platform of the client in real time, so the user can view the operating status and lubrication status of the device in real time through a mobile terminal, and can timely know the device failure situation and the abnormal situation of the lubrication system, so as to go to the fault point in time to check the fault, go to the lubrication system with abnormal report in time to check the lubrication system status and replenish grease, etc. Since the device management platform can analyze various signals collected through data comparison with the database, calculate the type of the operating status of the device, and transmit data to the lubrication controller through the device management platform, adaptively adjust or remotely manually adjust the lubrication strategy of the lubrication system through the terminal, the degree of automation is significantly improved, and the manual labor intensity and maintenance cost are greatly reduced.
