With the development of information technology, the authors envision that the key of improving coal mine safety is how to get real-time positions of miners. In this paper, they propose a prototype system for real-time coal miner localization and tracking based on self-organized sensor networks. The system is composed of hardware and software platform. They develop a set of localization hardware devices with the Safety Certificate of Approval for Mining Products include miner node, wired fixed access station, and base with optical port. On the software side, they develop a layered software architecture of node application, server management, and information dissemination and broadcasting.
