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 a comprehensive status monitoring and management experimental platform for mine electromechanical equipment. Background Art

[0002] In order to ensure the safety and operating efficiency of mine electromechanical equipment, comprehensive monitoring and management have become an important issue 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 evaluation 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 application publication number CN117740587A can realize the comprehensive performance testing functions of bearing rotors under friction and wear, such as bearing wear and life prediction, lubrication performance test of sliding bearings, vibration characteristics of rotors under different friction forces; but the invention lacks a more intelligent communication system, and also lacks 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 simulate the fault status of bearings and gears at the same time, so that the fault characteristics are closer to the real state, but the experimental platform cannot simulate the lubrication state of the bearings, and it is 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 mining 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 includes a support bottom plate and also includes:

[0006] A guide rail is installed on the support bottom plate, and a driving 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 driving 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 stably operated, 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 upper 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 perform fingerprint sign-in by inspectors after each inspection, and then automatically enter the equipment status entry interface to transmit the equipment operating status to the host computer, and directly press the alarm button arranged 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, and 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, and 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 the inventory in real time, and record the use of spare parts to ensure that the necessary spare parts are provided in time when the 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 perform 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 the procurement project, including payback period, maintenance cost and potential risk assessment, and provide visual data reports to help decision makers comprehensively consider investment return 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 enterprise'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 specify the various parts that need to be purchased, such as bearings and gears, based on the needs of equipment maintenance and operation, and enter the specific models and quantities of these parts into the spare parts module to ensure that the system can accurately record and manage this information;

[0018] S2. The spare parts module automatically retrieves price information provided by various suppliers based on the input parts parameters. This process ensures that purchasers can obtain the latest market quotations through real-time data connection and analysis functions, and provides a basis for subsequent purchase decisions;

[0019] S3. After obtaining the price information, the purchase inquiry module will automatically select several purchasing solutions that meet the requirements according to the set conditions and budget. This process not only considers the price, but also analyzes factors such as the supplier's reputation and delivery time to ensure the rationality and feasibility of the selected solution;

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