[0002] Rural construction craftsmen play a vital role in rural construction. However, the existing online craftsman training system generally adopts a unified training model, which is unable to provide personalized training based on the skill level, work experience and actual needs of different craftsmen. This "one-size-fits-all" training method is not only inefficient, but also easily leads to ineffective learning, making it difficult for craftsmen to gain substantial skill improvement in training.

[0003] For example, the Chinese patent publication number CN117094597A, named "A Visualized Craftsman Online Training System", includes: a job selection module for practitioners to select job categories; a knowledge learning module matches job knowledge according to job categories; a standard generation unit generates a three-dimensional standard building according to the job category; a step generation unit generates construction steps according to the three-dimensional standard building and job knowledge, and each camera collects a two-dimensional building image of the actual building; a virtual generation unit generates a three-dimensional virtual building according to each two-dimensional building image and the position of each camera; a deviation calculation unit calculates the coordinate deviation value of the three-dimensional virtual building and the three-dimensional standard building at each same position; a suggestion generation unit generates improvement suggestions according to each coordinate deviation value; a scoring unit calculates the overall deviation value according to the coordinate deviation value, and then processes the overall deviation value to obtain a training score; and an assessment unit generates an assessment result of passing the assessment when the training score is greater than the preset score threshold. The disadvantage is that it can only select the job category, and cannot provide personalized training for different craftsmen's skill levels, work experience and actual needs. It is inefficient and easily leads to ineffective learning, and it is difficult for craftsmen to obtain substantial skill improvement in training. Summary of the invention

Parameterized query can effectively prevent SQL injection attacks and improve the security of the system. By precompiling SQL statements and passing in parameter values, the system can automatically handle special characters and malicious input to avoid potential security threats. Parameterized query can not only improve the security of the system, but also optimize the query performance to a certain extent, because parameterized query can reduce the number of times the database parses and compiles the query statement, especially for frequently executed query statements, this optimization effect is more obvious. The system supports the use of multiple conditions such as ID number, mobile phone number or email address to retrieve electronic certificate information, which provides a more flexible and convenient query method for craftsmen. At the same time, this design also increases the versatility of the system and can adapt to query needs in different scenarios.

[0017] The present invention is further configured as follows: the Redis cache technology includes: Store the electronic certificate information as the value and the craftsman's unique identifier as the key in Redis; Set expiration time for cached electronic certificate information; When the electronic certificate information in the database is updated, the data in the Redis cache is updated synchronously.

[0018] In this technical solution, by storing the electronic certificate information as the value and the craftsman's unique identifier as the key in Redis, the system can quickly retrieve the corresponding electronic certificate information based on the craftsman's unique identifier. The memory storage feature of Redis makes data access much faster than traditional database queries, thereby significantly improving the response speed and performance of the system. Setting an expiration time for the cached electronic certificate information ensures that the data in the cache will not occupy the memory for a long time, while also avoiding the problem of inaccurate query results caused by data expiration, ensuring the freshness of the cached data, and enabling craftsmen to obtain the latest data when querying the electronic certificate information. When the electronic certificate information in the database is updated, the system can synchronously update the data in the Redis cache, ensuring the consistency of the data between the database and the cache, and avoiding confusion or errors in the query results caused by inconsistent data. By using Redis caching technology, the system can reduce the frequency of access to the database, reduce the load pressure on the database, and optimize the use of system resources. At the same time, caching technology can also improve the scalability of the system, allowing the system to better cope with scenarios such as high concurrent access.

[0019] The present invention is further configured as follows: the online examination unit comprises: Randomly select questions from the question bank to form the test paper; Conduct remote monitoring, record video and screen activity during the exam, and continuously perform facial recognition on candidates; After the exam, the test will be automatically graded and the craftsmen will be provided with instant feedback on the results and analysis of wrong questions.

[0020] In this technical solution, by randomly extracting questions from the question bank to form the test paper, it is ensured that the questions encountered by each craftsman in the exam are random and unique, effectively avoiding the possibility of cheating and plagiarism, and ensuring the fairness and impartiality of the exam.

The test paper is marked with barcode technology, and the barcode is associated with the candidate's unique identifier, making the receipt, correction and archiving of the test paper more standardized and orderly, avoiding problems such as confusion and loss of test papers, and improving the efficiency and quality of test management.

[0050] The data statistical analysis module includes: Statistics on the number of participants, training duration and completion rate of different certificate types and training types; Assess the skill level of craftsmen based on their learning history and test scores; Categorize and label the skill levels of craftsmen; Analyze the pass rates of different training types and examination methods, and collect statistics on training types or examination methods with lower pass rates.

[0051] In this technical solution, the number of participants, training duration and completion rate of different certificate types and different training types can be counted, which provides comprehensive data support for managers, helps to understand the craftsman's training participation, learning progress and completion, and provides a basis for subsequent training and management work. Through the learning history and test scores of the craftsman, the system can evaluate the craftsman's skill level, not only considering the craftsman's learning performance, but also comprehensively considering the performance in the learning process, making the evaluation results more comprehensive and accurate. The evaluation results help the craftsman understand his own skill level and provide a reference for the personalized customization of the training program. The system classifies and labels the skill level of the craftsman, which helps managers quickly understand the craftsman's skill characteristics and areas of strength, provides direction for the craftsman's career development, and enables the craftsman to choose the appropriate training and development path according to his own skill characteristics. By analyzing the pass rates of different training types and different test methods, the system can identify the training types or test methods with low pass rates, and conduct statistics and analysis on them, which helps to find problems and bottlenecks in the training process, and provides strong support for the optimization and improvement of the training program. At the same time, it also provides a reference for the improvement of the test method to improve the fairness and effectiveness of the test.
