The invention discloses a limited space operation safety control method and system, and relates to the technical field of operation safety control, and the method comprises the steps: recognizing the modal dominant change in a limited space operation process, and adjusting the interpretation priority and judgment reference weight of each piece of modal information according to the change of an operation stage; according to the modal dominant change of the current stage, judging whether the acquired multi-modal sensing signal is in an overall silent or abnormal silent state or not; establishing a time sequence causal chain between the behavior triggering event and the modal response to identify potential dangers; the cooperative stability among the multiple types of rhythm signals in the operation process is monitored; a response observation time window is set after the abnormal state occurs, and whether a safety intervention operation is triggered or not is judged by monitoring whether a multi-mode signal presents a self-recovery trend or not in the time window, and the safety intervention operation is performed. According to the invention, the problem that safety accidents cannot be timely and accurately identified and handled in the prior art is solved.

The application discloses a color-changing chest card for representing observation time length based on color change, and relates to the technical field of medical auxiliary devices. The color gradient of the color-developing coating intuitively reflects the observation time, and medical staff do not need to rely on timing tools or manual recording, but can quickly judge whether the observation time length of a patient meets the standard through visual observation, thereby greatly improving the efficiency and accuracy of observation monitoring. The opening area of the oxygen release hole is adjusted through a rotating disc, the oxygen release rate can be accurately controlled, the needs of different observation time lengths can be met, and the adaptability is high. The sealing cavity effectively isolates external environmental interference, the annular porous color-developing agent carrier ensures that the color-developing reaction is uniform and stable, the problem of local uneven color is avoided, and the color-developing result is more reliable. The application replaces the traditional manual timing and recording and checking links, reduces the probability of human errors, and helps improve the operation efficiency of medical places.

The invention relates to the technical field of artificial intelligence, and discloses an intelligent after-sales customer service method and system and a storage medium, and the intelligent after-sales customer service method comprises the following steps: S101, determining an operation moment and an operation type; s102, determining upper and lower bounds of a time window; step S103, calculating a time priori density and a time priori mask; step S104, determining an event moment; step S105, outputting answer probability distribution; and S106, when the answer confidence is lower than the lower limit of the answer probability or the observation duration is smaller than the upper limit of the time window, outputting the additional shooting duration, otherwise, outputting the customer service answer. According to the method, response delay after equipment operation is accurately modeled, time delay distribution is predicted and a time window is determined based on equipment meta-information and an operation type, time prior density and a mask are injected into an attention mechanism, constraint evidence is retrieved to an effective time period, and irrelevant interference and evidence obtaining in a wrong time period are avoided.
