[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, 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 embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] like Figure 1-5 As shown, a simulation test system for a universal printer includes an intelligent test control module, a modular test module, an automatic data processing module and a remote control assistance module;

[0050] The intelligent test control module automatically selects and adjusts the test strategy according to the test requirements to achieve intelligent management of the test process;

[0051] The modular test module can quickly reconfigure the test tool according to different test requirements, thereby improving the flexibility and adaptability of the test;

[0052] The automated data processing module automatically collects, analyzes and stores test data, generates test reports, and improves data processing efficiency;

[0053] The remote control assistance module supports personnel to access and control the test system for fault diagnosis and maintenance;

[0054] Further, the intelligent test control module includes a test strategy selection unit, a fault diagnosis unit and a predictive maintenance unit;

[0055] The test strategy selection unit automatically selects a test plan according to the test target;

[0056] The test strategy selection unit uses fuzzy logic to determine the best test strategy based on test requirements, such as load, speed, and paper type. Fuzzy logic can handle the uncertainty of test conditions, such as "high load" or "fast printing", and automatically select the most appropriate test plan;

[0057] Automatically select test plans according to test objectives, use rule-based expert systems, and combine fuzzy logic to handle uncertainty and ambiguity. The calculation formula of fuzzy logic can be expressed as:

[0058]

[0059] x indicates the specific parameter under test, such as print speed, print load, or paper type;

[0060] μ A (x) is the membership function, which indicates the degree of membership of the input variable x to a certain fuzzy set A;

[0061] a and b are parameters used to adjust the shape of the curve;

[0062] A represents different fuzzy sets, such as “high load”, “low load”, “high-speed printing”, “low-speed printing”, etc.;

[0063] Assume the following fuzzy rules:

[0064] If the print speed is "High", select "Performance Test";

[0065] If the print load is "Low", select "Durability Test";

[0066] In this case, membership functions are defined to quantify "high" and "low":

[0067] For print speed v:

[0068] where v h is the center value of high speed, b h Control the width of the high speed range;

[0069] For print load l:

[0070] Among them l l is the center value of low load, b l Control the width of the low load range;

[0071] The decision-making process is as follows:

[0072] ① Input evaluation: Calculate the value of the membership function based on the current printing speed and load;

[0073] ② Rule evaluation: Use fuzzy logic reasoning mechanisms (such as maximum-minimum synthesis) to evaluate the activation level of each rule;

[0074] ③Decision making: Select the corresponding test strategy based on the most activated rule;

[0075] In this way, the test strategy selection unit can flexibly handle the uncertainty and ambiguity in the test requirements and automatically select the most appropriate test strategy.

[0076] The fault diagnosis unit uses an algorithm to analyze the test data and identify the fault mode;

[0077] The fault diagnosis unit uses CNN to analyze the test data of the printer under different operating conditions and identify abnormal patterns. CNN can identify complex spatial patterns, such as abnormal behavior of the print head or deviation of paper feeding, thus achieving early diagnosis of faults.

[0078] CNN can identify abnormal patterns in print quality, such as uneven ink and alignment errors. The core calculation of CNN includes convolutional layers, activation functions, pooling layers, etc.:

[0079] Convolutional Layer:

[0080] Z ij (l) is the output of the i-th convolution kernel at the j-th position in the l-th layer; is the weight of the kth convolution kernel in the lth layer; The input of the mth convolution kernel in the l-1th layer at the jth position; b i (l)is the bias term of the lth layer;

[0081] Activation function (ReLU):

[0082] is the output after the ReLU activation function; is the output of the convolutional layer;

[0083] Pooling layer (max pooling):

[0084] is the output of the pooling layer; The input of the pooling operation is usually the value of a region;

[0085] The fault diagnosis unit can automatically identify the printer's fault mode:

[0086] ① Data preprocessing: convert the printed sample images into a format suitable for CNN input, such as normalization, resizing, etc.;

[0087] ② Feature extraction: Automatically extract image features through multiple convolutional layers and pooling layers;

[0088] ③Classification: Map the extracted features to different fault categories through the fully connected layer;

[0089] ④ Training: Use the labeled fault and normal samples to train the CNN, and adjust the weights and biases to minimize the classification error;

[0090] ⑤ Fault identification: Input new printing samples into the trained CNN and output the fault category.

[0091] The predictive maintenance unit analyzes usage and test data to predict maintenance needs;

[0092] The predictive maintenance unit uses LSTM networks to analyze printer usage and test data to predict maintenance needs. LSTM can process time series data to predict the replacement cycle and maintenance time of consumables, thereby reducing unexpected downtime.

[0093] The predictive maintenance unit uses a long short-term memory network (LSTM) to predict the maintenance cycle of the printer. The recursive calculation formula of LSTM is:

[0094] Forget gate: f t =σ(W f ·[h t-1 , x t ]+b f )

[0095] Input gate: i t =σ(W i ·[ht-1 , x t ]+b i )

[0096] Candidate cell states:

[0097] Cell status update:

[0098] Output gate: o t =σ(W o ·[h t-1 , x t ]+b o )

[0099] Hidden state: h t =o t *tanh(C t )

[0100] in:

[0101] Time step t represents a specific time point in the predictive maintenance process, which can be the beginning, end or any checkpoint of a printing task;

[0102] Input x t Represents the input data at time step t, which may include the performance indicators of the printer at that time step, such as printing speed, ink cartridge status, paper feeding status, printer temperature, etc.;

[0103] Hidden state h t represents the output of the LSTM unit at time step t, which contains information about the printer status at that time step and is used to predict future maintenance needs;

[0104] Cell State C t Represents the information storage inside the LSTM unit, which spans multiple time steps and is used to memorize the long-term state changes of the printer, such as the consumption rate of consumables, the wear of the print head, etc.;

[0105] Forget gate output f t Indicates that at time step t, the cell state C from the previous time step is determined t-1 How much information to discard in the long-term memory is analogous to deciding which short-term, unimportant printer state changes do not require long-term memory;

[0106] Input gate output i t Represents the decision of how much new information is allowed into the cell state at time step t, which can be associated with a new state change of the printer, such as a significant decrease in consumables or abnormal wear of the print head;

[0107] Candidate cell states Represents the candidate value of the new cell state that should be stored at time step t. It is calculated based on the current input and the previous hidden state and can represent the current state change of the printer, such as the remaining amount of the ink cartridge;

[0108] Output gate output o t Indicates how much cell state information will be output to the next hidden state at time step t, which can be associated with the long-term health trend of the printer, such as predicting the time for consumable replacement;

[0109] The LSTM network can capture the long-term dependencies of printer status and predict future maintenance needs, thereby optimizing the printer's maintenance plan and improving operational efficiency;

[0110] The intelligent test control module can effectively meet the simulation test requirements, improve the automation and intelligence level of the test, and ensure the performance and reliability of the printer.

[0111] Further, the modular test module includes a basic test unit and a module identification and configuration unit;

[0112] The basic test unit provides a common interface and basic functions to support the access of different test components;

[0113] The basic test unit defines a set of standard interfaces, such as electrical interfaces and communication protocols (such as TCP / IP, serial communication, etc.), to ensure seamless access to different test components, including power management, data acquisition, control logic, etc., to provide necessary support for the connected test components. According to different test requirements, select the corresponding test components (such as sensors, actuators, etc.) and access the basic test unit through the universal interface;

[0114] The module identification and configuration unit automatically identifies the newly added module and performs configuration;

[0115] When a new module is connected, the module type and function are automatically identified through a preset identification mechanism (such as scanning the module logo, reading module information, etc.). Based on the identification results, the module parameters are automatically configured, such as setting communication parameters, configuring input and output ports, etc., to integrate the functions of the new module into the overall test process to ensure that the module can work together with other components.

[0116] Further, the automated data processing module includes a data acquisition unit, a data analysis unit, a report generation unit, and a data storage and management unit;

[0117] The data acquisition unit collects printer performance data in real time;

[0118] In this embodiment, the data collected by the data acquisition unit may come from various sensors deployed at key parts of the printer, and the operating data of the printer, such as temperature, ink cartridge remaining amount, printing speed, etc., may be read in real time through the sensors, and the read data may be transmitted to the data processing unit via wired or wireless means, and the transmitted data may be formatted into a unified data format for subsequent processing;

[0119] The data analysis unit analyzes the collected data to identify performance trends and anomalies;

[0120] Data preprocessing: Perform preprocessing operations such as cleaning, denoising, and normalization on the collected data to improve data quality;

[0121] Feature extraction: Extract key features from preprocessed data, such as temperature change rate, ink cartridge consumption rate, etc.

[0122] Trend analysis: Use statistical analysis, time series analysis and other methods to identify printer performance trends, such as performance degradation trends, consumables consumption trends, etc.

[0123] Anomaly detection: Use machine learning algorithms (such as clustering, classification, and anomaly detection algorithms) to identify abnormal patterns in data, such as sudden temperature rise, abnormal consumption of ink cartridges, etc.

[0124] The report generation unit automatically generates a test report based on the analysis results, and uses an automated tool (such as a programming script, a report generation tool, etc.) to generate a test report based on the summarized data;

[0125] The data storage and management unit is responsible for the safe storage and effective management of data.

[0126] Further, the remote control assistance module includes a remote access unit, a remote operation unit, a real-time monitoring unit, and a log recording and auditing unit;

[0127] The remote access unit provides a secure remote login function;

[0128] The remote operation unit allows remote execution of system control commands;

[0129] The real-time monitoring unit displays the system status and test progress in real time;

[0130] The logging and auditing unit records all remote operations and system events for problem tracking and security auditing.

[0131] This embodiment uses advanced testing technology and intelligent control strategies to achieve automation, intelligence and efficiency of the test process, improve test quality, reduce costs, and provide strong support for the continuous improvement and optimization of the printer;

[0132] Among them, the modular test module allows rapid reconfiguration of test tools to adapt to different test requirements, greatly shortens the test preparation time, and improves the flexibility of the test process. The intelligent test control module reduces manual intervention and improves the intelligence level of the test by automatically selecting and adjusting the test strategy. The fault diagnosis unit uses advanced algorithms such as CNN to analyze test data, improves the accuracy of fault detection, and thus improves the reliability of test results. The predictive maintenance unit predicts maintenance needs by analyzing usage and test data, helps optimize maintenance plans, and reduces unexpected downtime. The remote control assistance module provides remote access and operation functions, allowing users to monitor and control the test system no matter where they are, improving the user experience. The automated data processing module automatically collects, analyzes and stores test data, improves the efficiency and accuracy of data processing, and reduces the need for manual operation through automated and intelligent test processes, thereby reducing the cost of testing. The logging and auditing units in the remote control assistance module record all operations, enhancing the security and traceability of the system.
