By setting up a selection module, users can choose the experiments they are interested in, which can be experiments that have been done or experiments that have not been done, so that users have freedom of choice and improve user satisfaction with selection. Corresponding experimental information results are provided according to the experimental name selected by the user. By setting up an acquisition module, the standard operating steps corresponding to the experimental name selected by the user are compared with the safety level and operating specifications in the safety storage unit, and the safety level and safety operating specifications are provided, which helps users to comply with safety during the experiment. Operating procedures can reduce potential risks and the possibility of accidents in experiments. By setting up the experiment display module, the safety operation specification requirements, standard operating steps, erroneous experimental results, and experimental equipment and items corresponding to the experiment name selected by the user are displayed to the user, so that the user can clearly understand the operating steps required for the experiment and the expected experimental results, thereby improving the accuracy of experimental operations and the reliability of experimental results. By setting up the experiment comparison module, the user's actual operation steps are compared with the erroneous results to obtain historical comparison results. At the same time, the user's actual operation steps are compared with the standard operating steps and safety operation specification requirements to obtain actual comparison results and safety comparison results, which helps users to discover and correct erroneous operations in a timely manner, thereby improving the efficiency of the experimental operation process, and improving the accuracy of experimental operations and the reliability of experimental results.

By setting the matching unit, the database in the system can store the user information set and the experimental information set corresponding to the user information set. By matching the similarity with the user information, the system can intelligently screen out matching results with a similarity of 100%. By setting the display unit, the experimental information corresponding to the user information is displayed, which enables the user to quickly view the experimental information related to himself, thereby improving the user's experience. By viewing completed and unfinished experiments through the system, it is convenient for users to manage their own experimental progress, so that users have some understanding of their own experimental arrangements and can choose any experiment they want.

[0052] In particular, by setting the selection unit, the user can select an experiment name from completed or unfinished experiments, so that the user can easily select the experiment they are interested in. By setting the experiment storage unit to store the experiment name and the corresponding standard operating steps, the user can easily refer to the correct operating steps to ensure the accuracy and reliability of the experiment. By setting the historical storage unit to store the historical experiment result set of the user's completed experiments, including the completed experiment name set and the error result set corresponding to the completed experiment name set, the user can review the completed experiments and understand the experimental results and causes of errors in the completed experiments, thereby avoiding the same error from occurring when doing the same experiment, and improving the efficiency and accuracy of the experiment completion. By setting the experiment output unit to output the information results of the experiment, the user can easily obtain the results and analysis of the experiment.

[0053] In particular, by setting the experimental safety level and the corresponding action operations and experimental items stored in the safety storage unit, it can help users understand the safety risks of the experiment. Users can take corresponding safety protection measures according to the extracted results of the safety level to avoid accidents and dangerous situations in the experiment. By setting the safety prediction unit to compare the standard operating steps with a similarity of more than 98% according to the experiment name selected by the user, and extracting the corresponding action operations and experimental items, the user can obtain accurate operation guidance during the operation process, reducing the error rate of experimental operations and ensuring the accuracy of experimental results.

[0054] In particular, by setting up a step display unit, the standard operating steps of the experiment selected by the user are displayed, helping the user to perform the experimental operation correctly and improving the accuracy and safety of the operation; by setting up an error display unit, the errors that occurred during the operation of the completed experiment are displayed to avoid the user making errors in the same step; by setting up the operation specification display unit, the operation specifications of the experiment selected by the user are displayed, which is convenient for the user to view the safe operation specifications in real time, thereby improving the safety of the user during the experiment; by setting up the experimental operation unit, the experimental operation is performed according to the operation specifications and standard operating steps, thereby ensuring the accuracy and repeatability of the experiment.

[0055] In particular, by setting up a historical comparison unit to compare the user's actual operation steps with the erroneous results in historical experiments, it can help users understand previous operation errors and prevent users from making mistakes in the same place, thereby improving the accuracy and efficiency of the experiment. By setting up a standard comparison unit to compare the user's actual operation steps with the standard operation steps, it can be evaluated whether the user's experimental operation meets the standard requirements, so that the user can make corrections based on the actual comparison results to ensure that the user's actual operation steps reach the standard operation level. By setting up a safe operation comparison unit to compare the user's actual operation steps with the safe operation specification requirements, it can be ensured that the user's operation in the experiment meets the safety requirements, which helps to avoid safety accidents and risks in the experiment and improves the safety of the user during the experiment.
