[0002] With the rapid development of information technology, enterprises have an increasing demand for printing. Traditional printing methods have many problems, such as low efficiency, waste of resources, and low security. In order to solve these problems, digital operation and maintenance methods and systems have emerged. Digital operation and maintenance methods and systems improve printing efficiency, reduce operating costs, and ensure enterprise information security by informatizing and intelligentizing the printing process.

[0003] For example, the invention patent with announcement number: CN118446409A is an enterprise digital operation and maintenance abnormal status monitoring and early warning system. After the data acquisition terminal collects data, the data processing module obtains the human status operation and maintenance values ​​of the enterprise at different stages, and then the abnormal status analysis module obtains the human status operation and maintenance value at the next moment. The judgment and early warning module makes abnormal judgments based on the threshold and performs early warning operations. The system collects and analyzes enterprise operation and maintenance data in real time, can more accurately monitor system status and predict potential failures, use machine learning algorithms to automatically identify abnormal states, and trigger early warning notifications in real time, reducing manual intervention and response time, effectively improving enterprise operation and maintenance efficiency, reducing failure risks, and ensuring the stability and reliability of enterprise digital operations.

[0004] For example, the invention patent with announcement number: CN116384715B is a robot operation and maintenance management method for a digital robot industry chain, including: obtaining the operation data of the production units of the digital robot industry chain, and setting the operation and maintenance method for maintaining the operation data; according to the link data and operation data of the production units in the industry chain, personalizing the expansion of the production units to obtain expansion data; monitoring and operating the operation data and expansion data according to the operation and maintenance method to obtain operation and maintenance data; evaluating the operation and maintenance data, and issuing early warning reminders to production units that have abnormalities or changes.

Based on the system comprehensive energy efficiency assessment index, the operation and maintenance system is evaluated on energy efficiency and feedback is provided.

[0029] The third aspect of the present invention provides a device for a security operation and maintenance system based on file printing, including: a receiver, a processor and an early warning device.

[0040] Figure 2 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Reference Figure 2 As shown, the first aspect of the present invention provides a secure operation and maintenance system based on file printing, including: a device management module, an operation and maintenance management module, a job management module, a system comprehensive energy efficiency evaluation module and an operation and maintenance system database.

[0043] The equipment management module is used to collect equipment status data in real time, obtain the fault risk assessment index of each printing equipment after processing, and screen out each abnormal printing equipment according to the fault risk assessment index of each printing equipment.

[0044] Specifically, the failure risk assessment index of each printing device is obtained through processing, and the specific process is as follows: the devices include but are not limited to printers, copiers and scanners.

[0045] The device status data includes the continuous operation time of the device and the temperature, voltage, vibration frequency and noise intensity of the device.

[0046] The rated continuous operation time of the equipment, reference standard temperature, allowable deviation temperature, rated voltage, allowable deviation voltage, reference standard vibration frequency, allowable deviation vibration frequency and critical noise intensity are extracted from the operation and maintenance system database, and based on the equipment status data, a comprehensive analysis is performed to obtain the equipment failure risk assessment index. The equipment failure risk assessment index is used to quantitatively assess possible equipment failures and their severity, providing a basis for equipment failure early warning.

[0047] In a specific embodiment, the numerical expression of the failure risk assessment index of each printing device is: ; In the formula, represents the risk assessment index of the failure of the rth printing equipment, r represents the number of each printing equipment, , h represents the total number of printing equipment, t represents the number of each time monitoring point, , s represents the total number of time monitoring points, Indicates the continuous operation time of the rth printing device. represents the temperature of the rth printing device at the monitoring point at time t, It represents the voltage of the rth printing device at the monitoring point at time t. represents the vibration frequency of the rth printing device at the tth time monitoring point, represents the noise intensity of the rth printing device at the tth time monitoring point, Indicates the rated continuous operating time. Indicates the reference standard temperature, Indicates the allowable deviation temperature, Indicates the rated voltage, Indicates the allowable deviation voltage, Indicates the reference standard vibration frequency, Indicates the allowable deviation vibration frequency, represents the critical noise intensity, Indicates the equipment failure risk impact factor corresponding to the preset continuous operation time, Indicates the equipment failure risk impact factor corresponding to the preset temperature, Indicates the equipment failure risk impact factor corresponding to the preset voltage, Indicates the equipment failure risk impact factor corresponding to the preset vibration frequency, Indicates the equipment failure risk impact factor corresponding to the preset noise intensity.

[0048] It needs to be explained that when the absolute difference between the equipment's continuous operating time, equipment's temperature, voltage, vibration frequency and the rated continuous operating time, rated voltage, reference standard temperature, reference standard vibration frequency is greater, and the noise intensity of the equipment is greater, the corresponding equipment failure risk assessment index is greater, indicating that the risk of failure of the printing equipment is higher.

[0049] It should be explained that in this embodiment Indicates the equipment failure risk impact factor corresponding to the preset continuous operation time, Indicates the equipment failure risk impact factor corresponding to the preset temperature, Indicates the equipment failure risk impact factor corresponding to the preset voltage, Indicates the equipment failure risk impact factor corresponding to the preset vibration frequency, The equipment failure risk impact factor corresponding to the preset noise intensity is represented, and the numerical values ​​of the influence degree of the continuous operation time, temperature, voltage, vibration frequency, and noise intensity unit value of the equipment on the failure risk of the printing equipment are respectively represented. When used, the equipment failure risk impact factor corresponding to the continuous operation time, the equipment failure risk impact factor corresponding to the temperature, the equipment failure risk impact factor corresponding to the voltage, the equipment failure risk impact factor corresponding to the vibration frequency, and the equipment failure risk impact factor corresponding to the noise intensity can be directly obtained from the operation and maintenance system database. The corresponding relationship can be a preset mapping relationship. For example, the continuous operation time, temperature, voltage, vibration frequency, and noise intensity of the equipment are respectively mapped with the equipment failure risk impact factors corresponding to the continuous operation time, temperature, voltage, vibration frequency, and noise intensity preset in the operation and maintenance system database to form a mapping set. The real-time continuous operation time, temperature, voltage, vibration frequency, and noise intensity of the equipment are input into the mapping set to obtain the equipment failure risk impact factor corresponding to the continuous operation time, the equipment failure risk impact factor corresponding to the temperature, the equipment failure risk impact factor corresponding to the voltage, the equipment failure risk impact factor corresponding to the vibration frequency, and the equipment failure risk impact factor corresponding to the noise intensity. The mapping relationship can be one-to-one or a many-to-one relationship. The above influencing factors are all extracted from the operation and maintenance system database, and the value range is between 0 and 1.

[0050] It needs to be explained that the longer the equipment runs continuously, the temperature of the equipment may gradually increase due to the accumulation of heat generated by friction, current flow, etc. Continuous high temperature will accelerate the aging and wear of the equipment, thereby increasing the risk of failure. Long-term operation may cause loosening or wear of internal components of the equipment, thereby increasing the vibration frequency. Abnormal increase in vibration frequency is often a precursor to equipment failure. The longer the equipment runs continuously, the noise intensity may gradually increase due to wear and looseness of components. Noise may also mask early signs of equipment failure. Unstable voltage or excessive current may cause the equipment to overheat, thereby accelerating the aging of the equipment. At the same time, high temperature may also affect the performance of electrical components, thereby affecting the stability of voltage and current. Abnormal voltage or current may also cause changes in the electromagnetic force inside the equipment, thereby causing vibration.

[0051] It should be explained that comprehensive analysis of the continuous operation time, real-time temperature, voltage, current, vibration frequency, noise intensity and other parameters of printing equipment can not only reflect the equipment status more comprehensively, but also help to warn of failure risks in advance, thereby helping to optimize equipment maintenance plans, reduce operation and maintenance costs, and improve equipment energy efficiency. It is also conducive to ensuring the stable operation and efficient use of printing equipment.

[0052] Furthermore, each abnormal printing device is screened according to the failure risk assessment index of each printing device. The specific screening process is: extract the equipment failure risk assessment index threshold from the operation and maintenance system database, compare the failure risk assessment index of each printing device with the equipment failure risk assessment index threshold, if the failure risk assessment index of a printing device is higher than or equal to the equipment failure risk assessment index threshold, then the printing device is marked as an abnormal printing device, and an early warning feedback is performed; if the failure risk assessment index of a printing device is lower than the equipment failure risk assessment index threshold, then the printing device is marked as a normal printing device.

[0053] The operation and maintenance management module is used to obtain real-time equipment operation data, obtain the operation performance evaluation index of each printing equipment after processing, and perform task scheduling based on the failure risk evaluation index of each printing equipment and the operation performance evaluation index of each printing equipment.

[0054] Specifically, the operating performance evaluation index of each printing device is obtained through processing, and the specific process is: the real-time operating data of the device includes the printing speed, printing quality, energy consumption, average trouble-free operation time and the number of paper types supported by the device.

[0055] It should be explained that printing speed refers to the number of pages printed per minute by the device, taking black and white printing as an example. Print quality refers to the clarity, detail and color accuracy of the printed document or image. It is usually measured by resolution (DPI). The higher the DPI, the more delicate the printing effect.

[0056] It should be explained that modern printing devices have interfaces that communicate with computers or other management systems, and real-time data on printing speed can be directly read through these interfaces. The current print resolution setting is usually displayed in the control panel or software settings of the printing device. Smart sockets can be used to monitor the real-time energy consumption of the device. The average trouble-free operation time can be calculated by analyzing the maintenance and fault logs of the device. Average trouble-free operation time = total fault interval time / number of faults, where all fault interval times are added together to obtain the total fault interval time. The fault interval time refers to the normal operating time between two faults. The paper types supported by the device can be obtained by consulting the user manual or specification sheet of the device.

[0057] It should be explained that under the same printing conditions, the faster the device prints, the greater its power consumption will generally be. This is because the device needs to consume more energy to drive components such as the print head and paper feed mechanism to operate at high speed. The longer the mean trouble-free operation time, the higher the stability and reliability of the device. This means that the device can maintain stable performance and output quality under long-term operation or high-load working conditions. The more paper types a device supports, the stronger its printing adaptability. Different types of paper have different ink absorption, thickness, hardness and other characteristics, which will affect the printing quality and output effect.

[0058] The critical printing speed, critical printing quality, critical energy consumption, average critical trouble-free operation time and critical number of supported paper types are extracted from the operation and maintenance system database, and the equipment operation performance evaluation index is obtained through comprehensive analysis based on the real-time operation data of the equipment. The equipment operation performance evaluation index is used to quantitatively evaluate the efficiency and stability of the equipment when performing tasks, and reflects the performance of the equipment when performing specific tasks, providing a basis for evaluating the comprehensive energy efficiency of the system.

[0059] In a specific embodiment, the numerical expression of the operating performance evaluation index of each printing device is: ; In the formula, represents the performance evaluation index of the rth printing equipment, Indicates the printing speed of the rth printing device. Indicates the print quality of the rth printing device. represents the energy consumption of the rth printing device, represents the average trouble-free operation time of the rth printing equipment, Indicates the number of paper types supported by the rth printing device. Indicates the critical printing speed, Indicates critical print quality, represents the critical energy consumption, represents the mean critical trouble-free operation time, Indicates the number of critical supported paper types. Indicates the impact factor of the printing equipment's operating performance corresponding to the preset printing speed. Indicates the impact factor of the printing equipment operating performance corresponding to the preset print quality. Indicates the impact factor of the printing equipment operation performance corresponding to the preset energy consumption, Indicates the impact factor of the printing equipment operation performance corresponding to the preset mean trouble-free operation time, Indicates the impact factor of the printing equipment's operating performance corresponding to the preset number of supported paper types.

[0060] It needs to be explained that the greater the printing speed, print quality, average trouble-free operation time and the number of paper types supported by the device, and the smaller the energy consumption of the device, the greater the corresponding device operation performance evaluation index, indicating that the performance of the printing device when performing specific tasks is better.

[0061] It should be explained that in this embodiment Indicates the impact factor of the printing equipment's operating performance corresponding to the preset printing speed. Indicates the impact factor of the printing equipment operating performance corresponding to the preset print quality. Indicates the impact factor of the printing equipment operation performance corresponding to the preset energy consumption, Indicates the impact factor of the printing equipment operation performance corresponding to the preset mean trouble-free operation time, Indicates the printing equipment operation performance impact factor corresponding to the preset number of supported paper types, which respectively indicates the numerical value of the impact of the unit values ​​of the equipment's printing speed, printing quality, energy consumption, average trouble-free operation time and the number of paper types supported by the equipment on the printing equipment operation performance. When used, the printing equipment operation performance impact factor corresponding to the printing speed, the printing equipment operation performance impact factor corresponding to the printing quality, the printing equipment operation performance impact factor corresponding to the energy consumption, the printing equipment operation performance impact factor corresponding to the average trouble-free operation time and the printing equipment operation performance impact factor corresponding to the number of supported paper types can be directly obtained from the operation and maintenance system database. The corresponding relationship can be a preset mapping relationship, for example, the equipment's printing speed, printing quality, energy consumption, average trouble-free operation time The operation time and the number of paper types supported by the device are respectively mapped with the device operation performance influencing factors corresponding to the printing speed, printing quality, energy consumption, average trouble-free operation time and the number of paper types supported by the device in the operation and maintenance system database. The real-time printing speed, printing quality, energy consumption, average trouble-free operation time and the number of paper types supported by the device are input into the mapping set to obtain the printing device operation performance influencing factor corresponding to the printing speed, the printing device operation performance influencing factor corresponding to the printing quality, the printing device operation performance influencing factor corresponding to the energy consumption, the printing device operation performance influencing factor corresponding to the average trouble-free operation time and the printing device operation performance influencing factor corresponding to the number of supported paper types, wherein the mapping relationship can be one-to-one or many-to-one. The above influencing factors are all extracted from the operation and maintenance system database, and the value range is between 0 and 1.

[0062] It should be explained that in this embodiment, the printing speed and the mean trouble-free operation time of the device are combined to evaluate the comprehensive efficiency of the device in long-term operation, which is particularly important for high-load printing environments. Considering the printing speed and energy consumption, it is possible to evaluate whether the device maintains low energy consumption while completing the printing task quickly, thereby maximizing cost-effectiveness. The print quality and the paper types supported by the device directly affect the user experience. High-quality printing and versatility can improve user satisfaction. Comprehensive analysis of the device's printing speed, print quality, the device's energy consumption, the mean trouble-free operation time, and the paper types supported by the device can help more comprehensively evaluate the performance of the printing device, thereby helping to ensure that the device can meet its business needs while optimizing cost and efficiency.

[0063] Furthermore, task scheduling is performed based on the failure risk assessment index of each printing device and the operating performance assessment index of each printing device. The specific scheduling process is: extracting the printing requirements of each task from the printing task queue, including the printing volume and paper type, and prioritizing the tasks according to the printing volume.

[0064] The job management module is used to obtain job execution progress data and obtain the system job efficiency evaluation index after processing.

[0065] The operation performance evaluation index of each target normal device is obtained and sorted in descending order. The task with the highest priority is assigned to the target normal device with the highest operation performance evaluation index. And so on. The remaining tasks are assigned to the corresponding high-performance devices according to the priority.

[0066] The job execution progress data is obtained and processed to obtain the system job efficiency evaluation index.

[0067] Specifically, the system operation efficiency evaluation index is obtained after processing, and the specific process is: the operation execution progress data includes the normal operation time, failure rate, equipment utilization rate, operation throughput and average operation response time of the system in a preset detection cycle.

[0068] It should be explained that the average job response time refers to the time from job submission to job processing start, the job throughput refers to the number of jobs that the system can process simultaneously, the system's normal operation time refers to the total time the system is available and running without failure, the equipment utilization rate refers to the proportion of the actual equipment usage time to the total time, and the failure rate refers to the frequency of system failures.

[0069] It should be explained that professional monitoring software, such as Nagios, Zabbix, SolarWinds, etc., can be used to monitor the operating status of the system in real time and record the normal operation time, job response time, and the number and time of system failures, so as to calculate the failure rate. Equipment management software can be used to record and report the use of equipment. Print management software has a job tracking function that can record the number of all print, copy and scan jobs.

[0070] It should be explained that the longer the system's normal operation time, the lower the equipment's failure rate. This is because the system's stable operation time increases and the number of failures decreases. High equipment utilization usually means that the equipment is used frequently. If the equipment is of good quality and properly maintained, the normal operation time may increase. High job throughput usually means that the equipment utilization is also high because the system is processing a large number of jobs. Low equipment utilization may indicate insufficient job throughput and the system may not be fully utilized. If the average job response time is short, it usually means that the system processes jobs efficiently and the job throughput may be large. When the system failure rate is high, it may lead to an increase in the average job response time because the system needs time to recover from the failure. A longer normal operation time helps maintain or increase job throughput because the system is stable and can process jobs continuously.

[0071] The critical normal operating time, critical failure rate and critical equipment utilization rate, critical operation throughput and critical average operation response time are extracted from the operation and maintenance system database, and based on the operation execution progress data, a comprehensive analysis is performed to obtain the system operation efficiency evaluation index. The system operation efficiency evaluation index is used to quantitatively evaluate the operation processing capability and efficiency of the system, and provides a basis for evaluating the comprehensive energy efficiency of the system.

[0072] In a specific embodiment, the numerical expression of the system operation efficiency evaluation index is: ; In the formula, represents the system operation efficiency evaluation index, Indicates the normal operation time of the system. represents the failure rate of the system, Indicates the equipment utilization of the system, represents the job throughput of the system, Represents the average job response time of the system, Indicates the critical normal operation time, represents the critical failure rate, represents the critical equipment utilization, represents the critical job throughput, represents the critical average job response time, Indicates the system operation efficiency impact factor corresponding to the preset normal operation time, Indicates the system operation efficiency impact factor corresponding to the preset failure rate, Indicates the system operation efficiency influencing factor corresponding to the preset equipment utilization rate, Indicates the system operation efficiency impact factor corresponding to the preset operation throughput, Indicates the system operation efficiency impact factor corresponding to the preset average operation response time.

[0073] It needs to be explained that the greater the system's normal operating time, equipment utilization and operation throughput, and the smaller the system's failure rate and average operation response time, the greater the corresponding system operation efficiency evaluation index, indicating that the system's operation processing capability is stronger and the efficiency is higher.

[0074] It should be explained that in this embodiment Indicates the system operation efficiency impact factor corresponding to the preset normal operation time, Indicates the system operation efficiency impact factor corresponding to the preset failure rate, Indicates the system operation efficiency influencing factor corresponding to the preset equipment utilization rate, Indicates the system operation efficiency impact factor corresponding to the preset operation throughput, The system operation efficiency influencing factors corresponding to the preset average operation response time respectively represent the numerical values ​​of the influence of the normal operation time, failure rate, equipment utilization rate, operation throughput and average operation response time unit values ​​on the system operation efficiency. When used, the system operation efficiency influencing factors corresponding to the normal operation time, the system operation efficiency influencing factors corresponding to the failure rate, the system operation efficiency influencing factors corresponding to the equipment utilization rate, the system operation efficiency influencing factors corresponding to the operation throughput and the system operation efficiency influencing factors corresponding to the average operation response time can be directly obtained from the operation and maintenance system database. The corresponding relationship can be a preset mapping relationship, for example, the normal operation time, failure rate, equipment utilization rate, operation throughput and average operation response time of the system. The operation throughput and average operation response time are respectively mapped with the system operation efficiency influencing factors corresponding to the normal operation time, failure rate, equipment utilization rate, operation throughput and average operation response time preset in the operation and maintenance system database to form a mapping set, and the real-time system normal operation time, failure rate, equipment utilization rate, operation throughput and average operation response time are input into the mapping set to obtain the system operation efficiency influencing factors corresponding to the normal operation time, the system operation efficiency influencing factors corresponding to the failure rate, the system operation efficiency influencing factors corresponding to the equipment utilization rate, the system operation efficiency influencing factors corresponding to the operation throughput and the system operation efficiency influencing factors corresponding to the average operation response time, wherein the mapping relationship can be one-to-one or many-to-one. The above influencing factors are all extracted from the operation and maintenance system database, and the value range is between 0 and 1.

[0075] It should be explained that in this embodiment, comprehensive analysis of the system's normal operating time, failure rate and equipment utilization, the system's job throughput and average job response time can help identify system performance bottlenecks. For example, low equipment utilization may indicate that resources are not fully utilized, or a long average job response time may indicate insufficient processing capacity. It can also help to better allocate resources and avoid failures caused by excessive use of certain equipment, while ensuring that all equipment can operate effectively. By monitoring the failure rate and normal operating time, measures can be taken to improve the reliability of the system, reduce downtime, and thus improve operating efficiency. The average job response time is a direct indicator of user experience. Shortening the response time can improve user satisfaction and thus improve operating efficiency.

[0076] It should be explained that by comprehensively analyzing the system's normal operation time, failure rate and equipment utilization, the system's operation throughput and average operation response time, we can gain a comprehensive understanding of the system's operation efficiency, rather than just an evaluation of one dimension. It can also provide a scientific method and basis for evaluating and improving the system's operation efficiency, which helps to achieve more efficient and reliable operation and maintenance services.

[0077] The system comprehensive energy efficiency evaluation module is used to obtain the system comprehensive energy efficiency evaluation index based on the failure risk evaluation index of each printing equipment, the operation performance evaluation index of each printing equipment and the system operation efficiency evaluation index, and to evaluate the energy efficiency of the operation and maintenance system and provide feedback based on the system comprehensive energy efficiency evaluation index.

[0078] Specifically, a comprehensive analysis is performed to obtain a system comprehensive energy efficiency evaluation index. The specific analysis process is as follows: based on the failure risk evaluation index of each printing equipment, the operation performance evaluation index of each printing equipment and the system operation efficiency evaluation index, a comprehensive analysis is performed to obtain a system comprehensive energy efficiency evaluation index. The system comprehensive energy efficiency evaluation index is used to quantitatively evaluate the comprehensive energy efficiency of the operation and maintenance system, and to provide a basis for conducting system energy efficiency evaluation.

[0079] In a specific embodiment, the numerical expression of the system comprehensive energy efficiency evaluation index is: ; In the formula, represents the comprehensive energy efficiency evaluation index of the system, represents the risk assessment index of the rth printing equipment failure, represents the performance evaluation index of the rth printing equipment, represents the system operation efficiency evaluation index, Indicates the system comprehensive energy efficiency impact factor corresponding to the preset printing equipment failure risk assessment index, Indicates the system comprehensive energy efficiency impact factor corresponding to the preset printing equipment operation performance evaluation index, Indicates the system comprehensive energy efficiency impact factor corresponding to the preset system operation efficiency evaluation index.

[0080] It needs to be explained that when the printing equipment failure risk assessment index is smaller, the printing equipment operation performance assessment index and the system operation efficiency assessment index are larger, the corresponding system comprehensive energy efficiency assessment index is larger, indicating that the comprehensive energy efficiency of the operation and maintenance system is higher.

[0081] It should be explained that in this embodiment Indicates the system comprehensive energy efficiency impact factor corresponding to the preset printing equipment failure risk assessment index, Indicates the system comprehensive energy efficiency impact factor corresponding to the preset printing equipment operation performance evaluation index, It indicates the system comprehensive energy efficiency impact factor corresponding to the preset system operation efficiency evaluation index, which respectively indicates the numerical value of the influence of the unit value of the printing equipment failure risk evaluation index, the printing equipment operation performance evaluation index and the system operation efficiency evaluation index on the system comprehensive energy efficiency. When used, the system comprehensive energy efficiency impact factor corresponding to the printing equipment failure risk evaluation index, the system comprehensive energy efficiency impact factor corresponding to the printing equipment operation performance evaluation index and the system comprehensive energy efficiency impact factor corresponding to the system operation efficiency evaluation index can be directly obtained from the operation and maintenance system database. The corresponding relationship can be a preset mapping relationship, for example, the printing equipment failure risk evaluation index, the printing equipment operation performance evaluation index The index and the system operation efficiency evaluation index are respectively mapped with the system comprehensive energy efficiency impact factors corresponding to the printing equipment failure risk evaluation index, the printing equipment operation performance evaluation index and the system operation efficiency evaluation index preset in the operation and maintenance system database to form a mapping set, and the real-time printing equipment failure risk evaluation index, the printing equipment operation performance evaluation index and the system operation efficiency evaluation index are input into the mapping set to obtain the system comprehensive energy efficiency impact factor corresponding to the printing equipment failure risk evaluation index, the system comprehensive energy efficiency impact factor corresponding to the printing equipment operation performance evaluation index and the system comprehensive energy efficiency impact factor corresponding to the system operation efficiency evaluation index, wherein the mapping relationship can be one-to-one or many-to-one. The above-mentioned impact factors are all extracted from the operation and maintenance system database, and the value range is between 0 and 1.

[0082] It should be explained that a high failure risk assessment index usually means that the device is more likely to fail, which will directly affect the device's operating performance. Frequent failures will cause the operating performance assessment index to decrease. Through the failure risk assessment index, preventive maintenance can be performed to improve the device's operating performance assessment index. A high device's operating performance assessment index means that the device can complete printing tasks faster and with higher quality, which helps to improve the system's operating efficiency assessment index. Assigning tasks based on the operating performance assessment index can ensure that efficient devices take on more work, thereby improving the overall system operating efficiency. A high failure risk assessment index may cause equipment downtime, reduce the number of available devices, and thus reduce the system operating efficiency assessment index. By controlling the risk of failure, the adverse effects on system operating efficiency can be reduced and the efficiency level can be maintained or improved.

[0083] It should be explained that the equipment failure risk assessment index, equipment operation performance assessment index and system operation efficiency assessment index together constitute an assessment framework to help managers understand and optimize the overall performance of printing equipment from different perspectives. By comprehensively analyzing these indexes, the status of the printing system can be more comprehensively grasped, and corresponding management measures can be taken to improve overall operational efficiency and service quality.

[0084] Furthermore, the operation and maintenance system is energy-efficiently evaluated and fed back according to the system comprehensive energy efficiency evaluation index. The specific evaluation process is as follows: the system comprehensive energy efficiency evaluation index threshold is extracted from the operation and maintenance system database, and the system comprehensive energy efficiency evaluation index is compared with the system comprehensive energy efficiency evaluation index threshold. If the system comprehensive energy efficiency evaluation index is higher than or equal to the system comprehensive energy efficiency evaluation index threshold, the system energy efficiency evaluation is marked as qualified; if the system comprehensive energy efficiency evaluation index is lower than the system comprehensive energy efficiency evaluation index threshold, the system energy efficiency evaluation is marked as unqualified, and the evaluation result is fed back.

[0085] In a specific embodiment, the process of providing feedback on the evaluation results is as follows: Step 1: Automatically generate an evaluation report, which contains the actual value, threshold, evaluation result (qualified or unqualified) of the system comprehensive energy efficiency evaluation index, and necessary analysis instructions. Step 2: Clarify the feedback object, including system administrators, operation and maintenance teams, management or relevant departments. Step 3: According to the feedback object and urgency, select an appropriate feedback method, such as email, text message, system notification, conference call or paper report. Step 4: Send the evaluation report through the selected method. Step 5: Record the time, object, content and other information of the feedback in the system. Step 6: For systems with unqualified evaluation results, it is necessary to formulate an improvement plan and track the implementation and effectiveness of the improvement measures.
