The invention provides a STAR-RIS auxiliary transmission passive Internet of Things performance enhancement method, and aims to solve the problems of half-space limitation and low energy and information transmission efficiency of an RIS auxiliary passive Internet of Things. According to the invention, the STAR-RIS is deployed between the passive BDs and the access point to assist the BDs to transmit information to the access point, so that the total space distribution of the BDs is realized. In addition, beamforming is constructed at an energy station configured with multiple antennas to improve energy transmission efficiency. The invention provides an iterative algorithm based on a double-layer frame, and aims to solve the problem of joint optimization of a beam forming vector based on NOMA and an STAR-RIS element coefficient, and maximize the system sum rate, thereby remarkably improving the performance of a passive Internet of Things system.

This application provides an intelligent processing method and related device for oral medical orders based on an AI badge recorder system. It collects audio data from emergency situations captured by medical personnel wearing AI badges. After noise reduction, enhancement, and voice separation, it obtains the doctor's spoken voice signal and the nurse's repeated voice signal. Relying on a pre-stored voiceprint feature database, it completes doctor's voice recognition and authorization determination. After authorization, the two voice signals are transcribed into medical order text and repeated text, respectively. Consistency verification is performed on the two texts. If the verification is successful, structured medical order data is generated and sent to the execution terminal to assist nurses in performing standardized medical procedures. This application abandons the traditional model of manual memorization, verbal verification, and subsequent paper recording, improving the accuracy of verbal medical order verification, circulation efficiency, and execution standardization, ensuring emergency treatment safety, achieving full traceability of medical orders, and adapting to the application needs of rapid emergency treatment.
