Indoor positioning-based natatorium personnel safety monitoring method

The invention discloses a natatorium personnel safety monitoring method based on indoor positioning, and the method comprises the steps: 1, building indoor positioning systems of natatorium personnel monitoring areas, and sequentially installing the indoor positioning systems of the monitoring areas in a monitoring environment according to the route sequence of entering a natatorium; 2, acquiring an electronic map corresponding to an indoor positioning system; 3, establishing a server monitoring network system, and networking with the indoor positioning system through an in-network server and a switch for data interaction; 4, the indoor positioning system in the monitoring area receives the data information and forwards the data information to an in-network server; and 5, the intra-network server establishes a natatorium personnel safety monitoring system which is composed of a trajectory tracking module, an abnormal trajectory monitoring module, a swimming pool safety index monitoring module and a safety ana
