摘要:In order to achieve indoor positioning, based on the distance positioning algorithm is essential, it designs a company using DecaWave DW1000 chip and STM32 embedded control chip using the TOF algorithm and ranging system, indoor location in wireless sensor network. The whole system is divided into hardware and software. The hardware part includes anchor nodes and node labels, set up node using DW1000 chip and STM32 chip combination, the software using C language to write the STM32 location algorithm and control information controller, complete data acquisition, transmission and processing functions, in order to get the node label and the anchor node distance.
