Indoor positioning method and device based on low power consumption BLE, and medium

Abstract

The invention discloses an indoor positioning method and device based on low power consumption BLE and a medium, and relates to the technical field of side end artificial intelligence, and the method comprises the steps: carrying out the grid unit vector division of indoor environment data, so as to obtain a monitoring sensor vector of a to-be-analyzed independent space; based on the monitoring sensor vector, through analysis of the influence degree of the senior citizen activities on the sensor, determining the influence weight parameter of the senior citizen activities on the monitoring sensor; determining an average impact value of the activities of the old people on the monitoring sensor through contribution analysis of the monitoring sensor; determining a to-be-optimized layout of the monitoring sensor through sparse matrix weight threshold judgment; performing monitoring sensor layout optimization on the to-be-optimized layout of the monitoring sensor to determine an optimization objective function; and performing weighting coefficient iterative operation on the optimization objective function, and determining the layout of the monitoring sensor. According to the method, the technical problem that the local solution and the measurement precision are insufficient in the optimal arrangement of the sensor in the state monitoring of the elderly living alone is solved.
