This invention discloses a clutter discrimination and suppression method based on multiple echo features, comprising: acquiring radar front-end clutter and target echo detection video data and dividing it into several connected regions; extracting multi-dimensional features and labeling prior information for each connected region; using the Relief feature selection algorithm to calculate and filter the weights of the multi-dimensional features, removing redundant features to obtain the optimal feature vector; using this feature vector to train a support vector machine classifier, and obtaining the optimal parameter model through cross-validation; acquiring measured clutter data, extracting corresponding features and inputting them into the model; and determining whether to remove clutter and retain targets based on the output. This invention effectively filters out dynamic clutter spots, avoids false deletion of weak targets, significantly reduces the false alarm rate of the system, and alleviates the computational burden of subsequent track processing.

The embodiment of the invention provides a data processing method and device, equipment and a storage medium. The method comprises the following steps: acquiring to-be-stored sensor data, storing the sensor data to a corresponding storage address in a data storage device, uploading information corresponding to the storage address to a cloud server, so that an upper computer accesses the to-be-stored sensor data based on the storage address, and accessing the to-be-stored sensor data based on a received data access request sent by the upper computer. And determining that request information in the data access request is matched with the verification information, and finally sending the sensor data to an upper computer.

This invention discloses an automatic airway secretion clearing and nursing system for neurosurgery based on negative pressure sensing technology, belonging to the field of medical and nursing technology. The system includes a main structure that integrates a main control unit, a negative pressure generation and regulation unit, a suction tubing and operating components, a sputum collection and processing unit, a bypass electromagnetic pressure relief valve, and a micro-positive pressure generator. The main control unit is connected to a multimodal sensor bus and operates a module wake-up scheduling mechanism. Based on the received multimodal data, it sequentially performs multi-level risk warning judgments. When the judgment meets the preset intervention conditions, the system performs physical pressure relief through the bypass electromagnetic pressure relief valve, and the micro-positive pressure generator injects positive pressure buffer airflow to counteract the backflow pressure. For high-viscosity secretions, the system converts the basic suction negative pressure into a pulsating negative pressure airflow by changing the opening of the electronically controlled throttle valve. It uses alternating shear force to destroy the internal structure of the secretions, avoiding mechanical tearing damage and maintaining fluid pressure balance.
