Passive indoor personnel state detection method based on PCA-Kalman

The invention provides a passive indoor personnel state detection method based on PCA-Kalman. The method comprises the steps of collecting the position coordinate of a test area, denoising original data, extracting the most contributive feature by using an improved PCA algorithm, reducing the dimension of CSI data, extracting the non-linear feature of an original position fingerprint, storing a processed CSI signal into a fingerprint database, and updating the fingerprint database in real time according to environment change; classifying the data in a true environment by using an SVM algorithm, dividing the detection area into multiple reference points, numbering the reference points according to an ascending order, collecting behavior state of personnel in the detection area, and transmitting the acquired CSI data and amplitude and phase changes to a server; and matching a personnel state detection result with data in the fingerprint database, and thus achieving detection on differentstates of the personnel in the indoor environment according to a matching result. According to the method, the time complexity of the algorithm is reduced, the personnel state detection rate is improved, and the errors are reduced.

Intelligent flood prevention on duty management method based on neural network algorithm

The invention provides an intelligent flood prevention on duty management method based on a neural network algorithm. The goal of performing on duty operation, control and management by simulating the concept of flood prevention on duty personnel is achieved. When the on duty work starts, information support is provided for human thinking simulation by intelligently sensing the flood condition information, the early warning information, the network public sentiment, the disaster condition information and the personnel state; then, through an intelligent thinking sub system, the goals of intelligent analysis of handled events or events to be handled, flood prevention situation analysis, government opinion cognition, emergency response and work deployment on the basis of the neural network algorithm are realized; after the human brain thinking is simulated, the intelligent operation can also be performed, and the operation includes affair routing inspection, report generation, early warning response, information issuing and on duty handing-over. The method provided by the invention can assist flood prevention personnel to start the work in the flood period; the problems of complicated flood prevention on duty affairs and insufficient personnel are solved; the flood prevention work efficiency can be improved; the in-time high-efficiency intelligent and scientific handling of the flood prevention affairs can be guaranteed.
