[0024] It should be noted that the current laboratory equipment management has the following problems: 1. Unfair equipment allocation: When the demand for equipment is large, how to fairly and reasonably allocate equipment becomes a difficult problem. Traditional allocation methods often lack transparency and fairness. 2. Insufficient equipment use training: Different equipment has different operating requirements and precautions, and scientific researchers need to receive corresponding training before use. However, traditional training methods often lack pertinence and systematicness. The embodiments of the present invention are intended to solve the above problems.

[0025] In the embodiment of the present invention, when a user needs to use laboratory equipment for chemical detection experiments, he needs to input the experimental equipment usage requirements, which include experimental projects, user information, required equipment and required time period, and then automatically determine whether the required equipment needs to be queued for use. For example, if the required equipment and required time period in a certain experimental equipment usage requirement overlap, it is necessary to queue up. At this time, the priority, credit and integrity of all corresponding user information will be retrieved to calculate the equipment usage cardinality of the user information. Then, the embodiment of the present invention will determine the deadline of the required time period, for example, the deadline is the first two hours of the required time period. At the deadline, all users will be sorted in descending order according to the equipment usage cardinality, so that the user information to which the equipment is assigned can be determined, that is, the user ranked first can use the required equipment. Then, the historical equipment usage data of the assigned user information will be retrieved, the historical equipment usage data will be analyzed, and equipment training information will be sent to the user account, and the equipment training information will be more personalized and accurate. Finally, the person in charge of the laboratory equipment custody will also upload the equipment return information, which includes the return time and condition. The user's credit and integrity will be updated based on the return time and condition, achieving effective supervision and feedback after the equipment is returned, and ensuring the long-term stable operation of the equipment.
