The invention discloses a self-service book cabinet and a control method thereof, the book cabinet comprises book storage grids for storing books, each book storage grid comprises a cabinet door, a sensor for sensing the opening and closing state of the cabinet door is arranged on the cabinet door, and a book inventory device is arranged in each book storage grid; a processing module which is usedfor judging the opening and closing states of the cabinet door according to output signals of the sensor; when the cabinet door is closed, the book inventory device is controlled to perform inventoryaccording to a set time interval, so an inventory result is obtained, missing book information is determined under the condition that the inventory result is not matched with an on-shelf book information table, and the missing book information is uploaded to a server, thereby enabling the server to associate the missing book information with a user account which opens a cabinet door most recently, and updating the on-shelf book information table. According to the method, missing books are found through multiple times of inventory, and then the books are associated with a previous user, so that security holes are blocked.

Self-service book cabinet and control method thereof

The invention discloses a campus vision monitoring system which comprises a visual function detector, a server and a management client side. The visual function detector is connected with the management client side through a server; the visual function detector is used for detecting color vision, astigmatism, agility degree, memory and vision of subjects and sending detection data to the server; the server receives the data sent by the visual function detector, analyzes the received data, collects, sends the visual change rates of the individual subjects to parents' mobile phones and sends theincidence rate of myopia, the incidence rate of color vision abnormalities and vision change trend of the subjects in the population data to client sides. The campus vision monitoring system improvesthe accuracy and convenience of vision detection of students, conducts statistics on the vision change rate, the incidence rate of vision and the incidence rate of color vision abnormalities of individuals and groups of the students, facilitates the mastering of the students' vision changes and trends and provide reliable data for the supervision and prevention of later students' vision.
