detailed description

[0022] Referring to FIG. 1, an intelligent laboratory management system according to the present invention includes:

[0023] a database, configured to store the participating experimental person identity comparison information and the teacher comparison information, wherein the database can be edited by the teacher.

[0024] In a specific solution, the identity of the participating experimental personnel and the teacher comparison information stored in the database may be added, deleted, and modified by the class teacher.

[0025] The human body feature recognition module is configured to collect human body feature information of the laboratory personnel, wherein the human body feature recognition module uses a fingerprint recognition device or a face recognition device.

[0026] In a specific solution, the human body feature recognition device may specifically adopt a fingerprint recognition device or a face recognition device, etc., and set a face recognition device at the laboratory door, and the image can be performed when the experimenter and the teacher pass through the laboratory door. Collection, convenient and fast.
