1. An intelligent desk haying a state monitoring function, wherein the intelligent desk comprises a desk body, an image acquisition device disposed on the desk body, and an AI recognition module, wherein the image acquisition device used for acquiring a human face image of a user, and inputting the acquired human face image into the AI recognition module, the AI recognition module is used for recognizing whether a human face in the input image is in an attention concentration state or not, which comprises utilizing a symmetry of two eyeballs, virtualizing, a position of a center of each eyeball according to spherical curvature of each eyeball in the images; combining it with positions of a center of each pupil in the images, virtualizing an gaze ray emitted from a center of each eyeball to a center of each pupil; determining whether attention is concentrated according to convergence of two gaze rays of two eyes, and if the gaze rays have no focus, or the time that the focus of the gaze rays stays in a certain area exceeds a preset time range. an recognition result is determined as lack of concentration; if the focus of the gaze rays moves within a preset time range, an recognition result is determined as in an attention concentration state: and the AI recognition module is generated by a background server and updated regularly;
the intelligent desk further comprises a communication module and a local prompting device, wherein the AI recognition module is capable of sending a recognition result of an attention concentration state to the background server and a first client of a monitoring party via the communication module, the local prompting device can be triggered according to the recognition result of an attention concentration state of the AI recognition module, the local prompting device is used to remind a monitored party using the intelligent desk, wherein the local prompting device comprises a control module and an execution module, wherein the control module is electrically connected to an output end of the AI recognition module; the execution module is a vibration motor to trigger a vibration of the intelligent desk; the control module is configured to receive the recognition result of the attention concentration state output by the AI recognition module, and to count the numbers of recognized state result of concentration and state result of lack of concentration, and to trigger the execution module to send out a vibration signal if a proportion of the state results of concentration is lower than a preset proportion threshold value;
the local prompting device is also used for communication connection with a second client of the monitored party, the first client of the monitoring party can receive images of the monitored party, and can send a local prompting request to the second client; in response to the local prompting request the second client triggers the local prompt device to send a vibration signal, or the second client itself sends a prompt signal, wherein the prompt signal sent by itself includes one or more of the second client receiving a message ring tone, a terminal of the second client playing a prompt interface, and a terminal of the second client producing a vibration.
