These problems directly restrict the practicability and scalability of intelligent equipment management systems.
[0004] In view of the above problems, the present invention proposes an intelligent equipment management method and its equipment management system, which integrates key technologies such as multi-modal perception, decision tree intelligent analysis, security authentication mechanism, and multi-level terminal interaction, constructs a closed-loop process from data collection, real-time transmission, intelligent judgment, automatic control to model self-learning and optimization, effectively improves the intelligent level and fault prediction ability of the system, and realizes the equipment management goal of high security, high reliability, and high response.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but is only for selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.
[0021] Please refer to Figure 1 , Figure 1 This is a flow chart of an intelligent equipment management method provided by an embodiment of the present invention, comprising the following steps: Step S1, collecting key operating parameters of equipment through multiple types of sensors and performing data processing.
[0022] S1-1. Initiate the security authentication process. The authentication unit of the security protection module conducts identity authentication on the equipment sensors accessing the system.
[0023] S1-2. Obtain the key parameters of the equipment through the sensors of the sensing module and use the key parameters as the original data. The key parameters include temperature, pressure, vibration, and current. The original data is obtained by various types of sensors, such as position sensors, environmental sensors, etc., covering all aspects of the equipment operation state. During the acquisition process, the sensors can combine self-calibration and filtering functions to improve the data quality.
[0024] Step S2. Transmit the encrypted data to the central node in real time through the communication module and complete data cleaning and redundant backup.
[0025] S2-1. The communication module transmits the sensor data to the central node in real time through the wired network and encrypts the data using a security protocol during the transmission process to prevent tampering and leakage.
[0026] S2-2. After reaching the calculation and decision-making module, the data management module preprocesses and stores the data. The preprocessing includes data verification, format conversion, and outlier filtering. The cleaned data is written into the database for long-term storage for historical trend analysis and model training.
[0027] In addition, the redundant unit of the security protection module synchronously backs up the key data to the backup storage during the storage process to prevent data loss caused by a single-point failure and enhance the system reliability.
[0028] Step S3. Use the decision tree model in the artificial intelligence engine to train, predict, diagnose, and generate results for the equipment state.
[0029] S3-1. Based on the historical operation data and fault records, use the decision tree model for fault diagnosis and state prediction. First, calculate the information entropy of the training data set. It is defined that the data set D contains n types of states, such as normal, warning, and fault. The specific definition of the information entropy is as shown in the formula:
[0030] Among them, is the information entropy of the data set D, D is the data set to be divided currently, n is the total number of state categories, is the proportion of samples belonging to the k-th class in the data set, is the logarithmic function with base 2.
[0031] Use the candidate features as nodes for division. The candidate features are the key parameters collected by the sensors. Calculate the information gain obtained by each feature for dividing the data set. Assume that the feature A has V possible values , let Indicates the subset of the dataset with the value of on feature A, and represent the number of samples in the dataset and the subset respectively. Then the information gain Gain(D,A) of feature A is specifically as shown in the formula:
[0032] Among them, is the information gain brought by feature to the dataset , is the information entropy of the dataset before partitioning, is the candidate partitioning feature, is the number of possible value types of feature A, is the v-th possible value of feature A, is the subset 's information entropy.
[0033] The greater the information gain, the greater the improvement in purity obtained by using feature A for partitioning. Based on this, in the decision tree training process, the feature with the highest information gain is recursively selected as the partitioning node, continuously generating branches until the stopping condition is met. The stopping condition is that the data purity of the leaf node is high enough or there are no remaining features to be divided.
[0034] The decision tree model trained by the above algorithm will be used as the knowledge base for equipment health status assessment.
[0035] S3-2, Real-time fault prediction and status assessment. Use the trained decision tree model to perform real-time inference and judgment on newly collected equipment data. The artificial intelligence engine unit calls the fault prediction function of the decision tree model and calculates the data at the current moment uploaded by the sensor one by one according to the decision tree rules. Specifically: Start from the root node of the decision tree, traverse along the corresponding branches according to the values of each sensing parameter. When reaching the leaf node, output the prediction result, such as determining the equipment status as "normal operation" or giving the specific fault type and confidence level. If the model outputs a fault warning or a performance degradation signal, corresponding decision information is generated.
[0036] The entire analysis process is completed in real time in the calculation decision module, which can detect abnormal signs at an early stage and make diagnostic decisions, providing a basis for subsequent control.
[0037] Step S4, According to the intelligent analysis result, perform fault warning, permission verification and control instruction issuance and execution through the terminal module.
[0038] S4-1, Information warning and presentation. If the abnormal state is detected in step S3, the system issues a warning through the multi-level control terminal, where the abnormal state includes potential faults, abnormal operations and equipment abnormalities; For example, alarm information is displayed on the local operation terminal, relevant equipment is highlighted on the interface of the remote monitoring center, and notifications are pushed to maintenance personnel through mobile terminals. The alarm information includes the fault location, severity, and recommended disposal measures, etc., facilitating timely response by personnel.
[0039] S4-2. When the decision requires active intervention in the equipment operation, control instructions are sent to the equipment through the terminal interaction module. The control instructions include emergency shutdown, switching to redundant component operation, or adjusting operation parameters. Before the instructions are issued, the authentication unit of the security protection module verifies the operator's authority and the integrity of the instructions to prevent unauthorized control actions. The instructions are sent to the equipment actuator through the communication network. If the main communication channel fails, the redundant unit automatically switches to the standby communication link to ensure reliable delivery of the instructions. After the equipment receives the instructions, its internal control unit performs corresponding actions to achieve intelligent management and control of on-site equipment.
[0040] S4-3. After execution, the system records the current decision instructions and the equipment response results in the data management module as the basis for future analysis and model optimization. If a fault shutdown occurs, information such as the fault cause and sensor readings at the time of shutdown is recorded to enrich the fault database.
[0041] Step S5. Collect execution feedback data and continuously optimize the decision tree model to achieve a closed-loop and intelligent evolution of equipment management.
[0042] S5-1. In this step, the data management module collects the data of the actual response and subsequent operation of the equipment in step S4, marks it, and incorporates it into the historical database.
[0043] S5-2. The artificial intelligence engine unit uses the updated database to retrain or adjust the parameters of the decision tree model, such as pruning the decision tree according to new fault samples or adding new branch nodes, continuously improving the model's recognition accuracy for equipment aging and new fault modes.
[0044] This feedback mechanism enables the system to have self-learning ability, gradually optimize the decision-making strategy, and thus form a closed-loop data stream of state perception - real-time analysis - scientific decision-making - precise execution.
[0045] Please refer to Figure 2 , Figure 2 which is an architecture diagram of an intelligent equipment management system provided by an embodiment of the present invention, including: a sensing module, a communication module, a computing and decision-making module, a terminal interaction module, a security protection module, and a data management module; The perception module is the information source of the entire system. It consists of various sensors and data acquisition devices deployed on the equipment and is used to obtain the operating status data of the equipment. The data collected by it is sent upstream through the communication module, enabling subsequent modules to monitor and analyze the equipment. Among them, the types of sensors can be selected according to the equipment type, including temperature sensors, pressure sensors, accelerometers, vibration sensors, current and voltage sensors, position and attitude sensors, which are used to perceive the environmental and performance parameters of the equipment in real time; the data acquisition device converts the analog signals of the sensors into digital data and performs preliminary filtering and calibration.
[0046] As the data transmission hub between the modules of the system, the communication module provides wired and wireless network communication functions, reliably and efficiently transmits the data collected by the perception module to the calculation and decision-making module, and sends the decision control instructions to the terminal and the equipment actuator to ensure real-time information sharing.
[0047] The communication module supports wired networks such as industrial Ethernet and CAN bus, as well as wireless communication methods such as Wi-Fi, 4G / 5G cellular networks, and wireless sensor networks. In the implementation process, standard protocols and middleware are used to ensure the interconnection and interoperability between different devices. At the same time, combined with encrypted communication and network monitoring, it cooperates with the security protection module to provide the confidentiality and integrity of data transmission.
[0048] In addition, it also supports network status monitoring and switching. When the main communication link is abnormal, it can quickly switch to the backup link to improve the robustness of system communication.
[0049] The calculation and decision-making module is the brain of the system. It includes an artificial intelligence engine unit and related calculation and processing units, which are used to deeply process and make decision inferences on the collected data.
[0050] The artificial intelligence engine unit is built-in with intelligent algorithm models such as decision trees, providing functions of fault diagnosis, performance evaluation, and prediction and decision-making, corresponding to the data analysis process in method step S3.
[0051] The calculation and decision-making module may also include a rule engine, which is used to correct or supplement the intelligent decision by combining expert rules. It is implemented through a high-performance processor or an industrial server and can be deployed on a cloud server, an edge computing gateway, or a local controller, depending on the application requirements.
[0052] As the interaction interface between people and the system and between the system and the actuator, the terminal interaction module consists of multi-level control terminals and human-machine interfaces, including various terminal devices at the field level and the remote level. It presents the analysis results of the calculation and decision-making module to the user in an intuitive way and receives user input or confirmation operations: Specifically, the on-site operation terminal enables on-site equipment operation and maintenance personnel to view the status and receive alarms; the remote monitoring terminal enables managers to centrally monitor the operation status of multiple pieces of equipment; and the mobile terminal enables operation and maintenance personnel to obtain alarm and status information at any time. On the other hand, the control unit of this module is also connected to the actuator of the equipment, and can apply the control instructions from the decision-making module to the actual equipment to complete the precise execution link.
[0053] The multi-level terminals work together through permission division and network connection. For example, the on-site terminal can directly stop the machine in case of emergency, while the remote terminal is used to approve major operations or overall maintenance plans.
[0054] The security protection module is a module that ensures the security and reliability of each module in the system, including an authentication unit and a redundancy unit. The authentication unit is responsible for the identity authentication and access control of the system to ensure that only authorized devices and users can access the data of the sensing module or issue control instructions. The redundancy unit provides backup and fault tolerance mechanisms for the key components of the system to improve the overall reliability. The security protection module also covers functions such as abnormal monitoring and emergency handling. For example, when it detects that a certain sensor fails, it notifies the operation and maintenance personnel to replace it in time, and enables the data of the redundant sensor to be used as a substitute. Through authentication control and fault tolerance redundancy, the security protection module builds a solid barrier for the stable operation of the system, ensuring that each link of equipment management is safe, controllable and highly available.
[0055] As an independent functional module, the data management module runs through sensing, decision-making and terminals, and is responsible for data storage, organization and service provision. It includes various types of data storage units, such as local databases, real-time databases and cloud databases, etc.
[0056] Its functions include: receiving and storing the raw data from the sensing module and the real-time data transmitted by the communication module; maintaining the historical data warehouse to store the long-term operation records of the equipment, maintenance and repair logs, and fault case libraries; providing data query and analysis interfaces to enable the calculation and decision-making module to efficiently obtain the data sets required for training models; and performing data life cycle management, such as regularly archiving old data, deleting redundant data and data compression.
[0057] In addition, the data management module is responsible for data consistency and accuracy verification. For example, it synchronizes multi-source data using timestamps, corrects sensor drift, and ensures unit and format uniformity when fusing data from multiple devices.
[0058] This module can also generate reports or visualization data as needed for the terminal interaction module to call. Since the data involved in equipment management may be huge and diverse, the data management module is usually deployed on high-performance data servers or distributed storage systems, and database management systems or big data platform technologies are used to ensure the efficiency and reliability of data reading and writing.
