Abstract

The invention provides a base station deployment optimization method and system based on UWB positioning. The method comprises the following steps: acquiring a deployable area of a base station in an indoor space, determining spatial constraints of the deployable area, carrying out grid division on the deployable area, randomly generating a group of base station position combinations in each grid, and recording the base station position combinations as initial base station position combinations; all base station populations in a deployable area are divided into two populations, an initial base station position combination is taken as an initial value, the minimum base station deployment GDOP, the minimum positioning root-mean-square error and the minimum base station number M are taken as optimization objectives, an improved adaptive genetic algorithm and a Levy flight strategy algorithm are adopted to perform position updating on base stations in the two populations, and the position of the base stations in the two populations is calculated. And thus, base station combination optimization is carried out, and an optimal base station deployment combination is obtained. According to the invention, the rationality of the base station deployment method can be improved.

Description

technical field [0001] The present application relates to the technical field of indoor positioning, in particular to a method and system for optimizing base station deployment based on UWB positioning. Background technique [0002] The current indoor space positioning technologies include ultrasonic technology, Bluetooth positioning technology, Wi-Fi positioning technology, and Zigbee positioning technology. The requirements for positioning perception have disadvantages such as low positioning accuracy and weak adaptability. UWB (ultra-wideband) positioning technology has become the most widely used wireless positioning technology in indoor positioning due to its advantages of strong penetrating power, strong adaptability to the environment, low power consumption and easy integration. [0003] At present, the base station deployment method of UWB positioning technology is mainly based on the experience of the staff and the traditional layout methods such as rectangle, star...
