Description

Technical Field

[0001] The present invention relates to the field of comprehensive monitoring and intelligent operation and maintenance of electromechanical equipment, and in particular to an experimental platform for comprehensive status monitoring and management of mine electromechanical equipment. Background Art

[0002] In order to improve the safety and operating efficiency of mine electromechanical equipment, comprehensive monitoring and management have become important issues in modern mine management. Traditional monitoring methods often rely on manual inspections, which make it difficult to grasp the operating status of equipment in real time, resulting in an inability to respond in time when a fault occurs, which in turn affects production efficiency and safety. Therefore, it is particularly important to establish a comprehensive status monitoring and management experimental platform to achieve real-time monitoring, fault prediction and status assessment of mine electromechanical equipment. This platform will help improve the safety and efficiency of mine production and meet the needs of modern mine management.

[0003] For example, the comprehensive bearing fault simulation test bench with application publication number CN101526422B can realize the comprehensive simulation of lubrication faults and mechanical faults, but lacks an effective fault analysis module and does not achieve true intelligent operation and maintenance; for example, a rolling bearing fault detection test bench with application publication number CN219798706U can realize the testing of bearings with different inner diameters, but the invention has low reliability due to the complex installation position of the bearings; for example, the comprehensive performance testing functions of bearing rotors under friction and wear such as bearing wear and life prediction, lubrication performance testing of sliding bearings, and vibration characteristics of rotors under different friction forces can be realized with application publication number CN117740587A; however, this invention lacks a more intelligent communication system, as well as an inspection entry and management system, and has low reliability; for example, the bearing-gear multi-fault coupling simulation test bench with application publication number CN101576438 can simultaneously simulate the fault states of bearings and gears, making the fault characteristics closer to the real state, but the experimental platform cannot simulate the lubrication state of the bearings, making it difficult to achieve comprehensive state monitoring. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a comprehensive status monitoring and management experimental platform for mine electromechanical equipment, aiming to solve the problems existing in the above-mentioned background technology.

[0005] The embodiment of the present invention is implemented as follows: a comprehensive state monitoring and management experimental platform for mine electromechanical equipment, including a support base plate, and further comprising:

[0006] A guide rail is installed on the support base plate, and a drive motor, a bearing grease lubrication fault simulation box, a gear box, a bearing seat and a simulated mechanical fault bearing are arranged in sequence along the length direction of the guide rail; wherein, the drive motor is connected to the input shaft through a coupling, and the bearing grease lubrication fault simulation box and the gear box are matched with the input shaft, and the gear box is matched with the output shaft, and the simulated mechanical fault bearing and the support bearing are matched with the output shaft;

[0007] A plurality of acoustic emission sensors and temperature sensor interfaces are installed on the support base plate, and vibration sensor interfaces are arranged on the bearing grease lubrication fault simulation box, the gear box and the bearing seat. After the corresponding sensors are connected to the acoustic emission sensor, the temperature sensor interface and the vibration sensor interface, the drive motor is started. When the rated working condition is stable, data is collected through the sensor, and the sensor transmits the collected data to the wireless terminal installed on the support base plate. After simple processing by the wireless terminal, the data is transmitted to the host computer for data analysis and processing;

[0008] The wireless terminal includes a paperless inspection entry and management system integrated with an RFID communication system and a signal receiving and transmission system;

[0009] Among them, a software system is set in the host computer connected to the experimental platform, and the software system includes a fault analysis module, a spare parts module, a purchase inquiry module and an investment evaluation module.

[0010] Preferably, the paperless inspection entry and management system is used to have the inspectors sign in with their fingerprints after each inspection, then automatically enter the equipment status entry interface, transmit the equipment operating status to the host computer, and directly press the alarm button on the wireless terminal to sound an alarm when a serious safety hazard occurs.

[0011] Preferably, the fault analysis module receives the collected data transmitted by the host computer, and the system transmits the mechanical fault data to the mechanical fault status analysis module in the fault analysis module. The mechanical fault status analysis module analyzes the fault type through the embedded machine learning algorithm and outputs the operating status to the screen in the form of animation; at the same time, the system transmits the lubrication status data to the lubrication status analysis module in the fault analysis module. The lubrication status analysis module analyzes the current lubrication status through the embedded machine learning algorithm and outputs the lubrication status to the screen in the form of animation.

[0012] Preferably, the spare parts module integrates the ERP system to manage and monitor the spare parts required for the equipment in real time, track inventory in real time, and record the use of spare parts to ensure that necessary spare parts are provided in time when equipment fails.

[0013] Preferably, the procurement inquiry module is embedded in the SRM supplier management system to integrate supplier information, automatically generate inquiry forms, and provide real-time data analysis and quotation comparison functions, so as to flexibly adapt to market changes and track historical records, thereby improving procurement efficiency and transparency and reducing costs.

[0014] Preferably, the investment evaluation module is used to conduct a comprehensive cost-benefit analysis of procurement projects, including payback period, maintenance cost and potential risk assessment, and provide visual data reports to help decision makers comprehensively consider investment returns and risk management when making procurement decisions.

[0015] Preferably, the investment evaluation module also has the ability to flexibly adjust evaluation parameters to adapt to changes in different projects and market environments, thereby ensuring the scientificity and accuracy of the company's procurement decisions.

[0016] In summary, the steps of the spare parts module, purchase inquiry module and investment evaluation module are as follows:

[0017] S1: Purchasing personnel identify the various parts they need to purchase, such as bearings and gears, based on equipment maintenance and operation requirements. They then enter the specific models and quantities of these parts into the spare parts module to ensure the system can accurately record and manage this information.

[0018] S2. The spare parts module automatically retrieves price information from various suppliers based on the input part parameters. This process, through real-time data connection and analysis, ensures that purchasing personnel can obtain the latest market quotes and provides a basis for subsequent purchasing decisions.

[0019] S3. After obtaining price information, the purchase inquiry module will automatically screen several suitable purchase options based on the set conditions and budget. This process not only considers price but also analyzes factors such as supplier reputation and delivery time to ensure the rationality and feasibility of the selected option.

[0020] S4. The selected procurement plans will be fed back to the procurement staff. After careful evaluation, the procurement staff will select the most appropriate plan and input the selected procurement plan and budget personnel information into the investment evaluation module. The module will conduct an in-depth analysis of the feasibility of the investment based on the current market environment and the company's financial situation.

[0021] S5. The investment evaluation module conducts a comprehensive analysis of the input information, including cost-effectiveness, payback period and potential risk assessment, and generates visual data reports to help procurement personnel make wise investment decisions. Once the investment plan is determined, the relevant information will be fed back to the procurement personnel again to ensure the transparency and efficiency of the entire procurement process.

[0022] The embodiment of the present invention provides an experimental platform for comprehensive status monitoring and management of mine electromechanical equipment, which has the following technical effects:

[0023] 1. Compared with traditional intelligent experimental platforms that simulate single bearing or gear faults, this application can simultaneously simulate bearing grease lubrication faults, gearbox oil lubrication faults, and bearing and gear mechanical faults. At the same time, it reserves interfaces for acoustic emission sensors, temperature sensors, and vibration sensors to better collect fault signals.

[0024] 2. Compared with traditional experimental platform management, this application realizes paperless inspection entry and management and integrates RFID communication system to urge inspection personnel to regularly inspect equipment and directly enter problems encountered during inspection into the corresponding module of the system, thereby facilitating timely maintenance and efficient management of equipment;

[0025] 3. Compared with traditional experimental platforms that lack investment evaluation inquiries, this application introduces spare parts modules, procurement inquiry modules and investment evaluation modules, which can ensure that spare parts for key equipment are in place in a timely manner, thereby reducing downtime, improving the efficiency of inquiries, enhancing transparency, and reducing procurement costs. At the same time, it ensures that enterprises can fully consider investment returns and risk management when making procurement decisions. BRIEF DESCRIPTION OF THE DRAWINGS
