Intelligent and Comprehensive Monitoring System for Swimming Pool

This paper introduces an intelligent and comprehensive monitoring system (ICMS) for swimming pool safety. The ICMS consists of underwater ultrasonic detection subsystem (UUDS), underwater video detection subsystem (UVDS) and virtual pool fence monitoring subsystem (VPFS). Multiple ultrasonic sensors in UUDS can detect drowning people in real time with a range up to 70 meters and cover the entire swimming pool. As a supplementary, UVDS can quickly find and locate drowning people by analyzing real time video sequences and assisting UUDS in realizing more accurate detection. The VPFS not only provides flexible and adjustable virtual pool fence which can detect pool intruders but also allows the hierarchical and cross domain video monitoring service for enhancing pool safety. The three subsystems are independent in operation but can complement one another in functionality. Distributed modular design based ICMS has good performances in flexibility, scalability and hierarchical monitoring. Besides, efficient network communication model and uniform data interface are employed to improve the robustness and high efficiency of the whole monitoring system. In addition, the ICMS provides client/server and browser/server hybrid structures which enables different network terminals to login to the system conveniently. Combined with a variety of technologies, ICMS can realize intelligent and comprehensive monitoring for pool safety.
