                | Abstract: This paper proposes a mine precise positioning algorithm based on multi-source collaborative sensing of the Internet of Things (IoT), aiming to improve single sensing technology for locating personnel or equipment in underground mines. First, a framework of IoT mine sensing and a positioning system are designed. Then, a mine precise positioning algorithm based on the multi-source collaborative sensing of the IoT is proposed from the principle of multi-source and multi-view positioning. Finally, experiments and comparative analysis are carried out between the proposed algorithm and the reference algorithm, and the comparison curve of probability and error of each algorithm at a fixed position is obtained. The proposed algorithm proves to be practical and advanced. |
