[0002] In modern industrial production, the stable operation of equipment is crucial for ensuring product quality, improving production efficiency, and guaranteeing the safety of operators.

[0003] Currently, many advanced equipment monitoring systems have begun to rely on sensor networks to collect real-time data for condition monitoring and fault diagnosis. These sensors enable engineers to remotely monitor the health of equipment and early warn of potential problems. However, this often depends on the stability of the sensors themselves. When a sensor fails, such as a short circuit, the data it provides may become unreliable or completely invalid, thus affecting the accuracy of the entire system's fault diagnosis.

[0004] In addition, traditional fault warning systems usually require operators to invest a large amount of time and effort to identify the fault source. From problem discovery to the issuance of repair tasks and finally to the completion of repairs, most of the communication and coordination in the entire process rely on manual intervention or through complex operation interfaces, which not only reduces the speed of responding to faults but also increases the risk of misjudgment to a certain extent.

[0056] Figure 5 Schematic diagram of the steps of a method for intelligent fault prediction and maintenance of the present invention. This method is applied to the aforementioned system for intelligent fault prediction and maintenance. Refer to Figure 5 As shown, to achieve precise and fast fault prediction, the present invention also provides a method for intelligent fault prediction and maintenance. The method includes the following steps:

[0057]

[0057] When the device starts to run, the sensor information acquisition module 1 collects the device operation data in real time and detects the short - circuit signal of the sensor, and then transmits the collected signal to the fault prediction and identification module 2;

[0058] S2. According to the chronological analysis of the sequence of sensor short - circuits and historical data, the fault prediction and identification module 2 analyzes the combined data and proposes various possibilities of fault prediction, and then outputs different potential fault information according to the magnitude of the possibility;

[0059]

[0058] After receiving the potential fault information, the fault warning and transmission module 3 sorts and summarizes it, and automatically generates a fault warning message, which is notified to the operator through the system interface or text message, etc.;

[0060] S4. After receiving the fault warning message, the operator uses a long - distance mobile QR - code scanning device to scan the QR - code on the device, supplement a complete detailed fault description, and upload the fault information to the system;

[0061]

[0059] S5. The fault integration and distribution module 5 in the system integrates the received fault information into fault details, and dispatches them to specialized maintenance personnel according to the type and area of the fault;

[0062] S6. After receiving the task, the maintenance personnel carry out maintenance work according to the fault details. After the task is completed, the task information is fed back to the system in a timely manner by scanning the QR - code. At this time, the task tracking and feedback module 6 records the completion of the maintenance task, updates the task status and priority to ensure effective tracking and management of the task.

[0063] When the user uses this intelligent fault prediction and maintenance system, the sensors in the system can collect the operation data of the device in a timely manner and monitor the short - circuit signal of the sensors. Subsequently, the fault prediction and identification module 2 will conduct chronological analysis by combining the sequence of sensor short - circuits and the historical data of the device and propose various possibilities of fault prediction, and then output different potential fault information according to the magnitude of the possibility. The system will sort and summarize the potential fault information to form a fault warning message and notify the operator. After receiving the information, the operator will conduct a check one by one. The operator can use a long - distance QR - code scanning device to supplement a complete fault description in the interface and then upload it to the system. The fault integration and distribution module 5 in the system will integrate the fault description uploaded by the operator into fault details, and then dispatch them to specialized maintenance personnel according to the type and area of the fault. After receiving the corresponding task, the maintenance personnel will carry out maintenance in a timely manner and give feedback. Through the combination of sensor short - circuit information, intelligent task allocation and QR - code scanning technology, the present invention realizes the rapid warning of equipment faults and intelligent task management, improves the fault handling efficiency, reduces the production downtime, and enhances the overall operation and maintenance efficiency of the equipment.

[0064] The methods adopted by the system fault prediction algorithm are respectively sensor short - circuit signal recognition, rule - based fault diagnosis, and fault mode recognition. That is, sensor short - circuit signal recognition means that when a sensor has a short - circuit or abnormal event, the system can automatically detect and record the time, type, and sequence of the short - circuit. Using these signals, the system can preferentially analyze the fault area related to the sensor; rule - based fault diagnosis means that by combining the health status of the sensor and the working parameters of the device, the system predicts the type of fault according to the set rules, reducing the troubleshooting scope of the operator; fault mode recognition is to identify the potential fault modes of the device through the joint analysis of multi - sensor data. If multiple sensors fail, the system can, according to the order and pattern of the faults, preferentially propose the most likely fault causes and affected areas.

[0065] The above has shown and described the basic principles, main features, and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above - mentioned exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non - restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0066] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
