Anti-drowning warning equipment and warning method thereof

Abstract

The invention discloses anti-drowning warning equipment and a warning method thereof. In the warning equipment, air flow intensity signals caused by water wave in a water area are detected by using a sensing device and converted into digital voltage signals, then water area model matching is performed by using a first microcontroller according to the digital voltage signals, whether warming signals are generated is determined according to the matching result, and the warming signals are used for indoor and outdoor audible and visual alarm through a first warning module and a second warning device of a front-end trigger device respectively; the anti-drowning warning equipment with the structure can effectively reduce the missing alarm and false alarm rate by the water area model matching of the first microcontroller and improve the safety performance, and experiments show that the safety indexes of the anti-drowning warning equipment can reach the safety indexes specified by NFP90-307 and ASTMF-2208 standards; moreover, the anti-drowning warning equipment has wide application range, and can be applied to standard swimming pools, ponds, small rivers and hot spring and environments of standard swimming pools, ponds, small rivers and hot spring under severe weather conditions.

Description

technical field [0001] The invention relates to an alarm device, in particular to an anti-drowning alarm device and an alarm method thereof. . Background technique [0002] With the continuous improvement of people's living standards, many families have begun to have private swimming pools, small pools in private gardens, rivers, etc. However, private swimming pools are not managed by special personnel like public swimming pools. If children or animals accidentally fall into the swimming pool and are not found or rescued in time, drowning accidents may occur. Therefore, drowning has become a very important safety issue. . [0003] In order to effectively solve the anti-drowning problem, many kinds of anti-drowning alarm equipment have appeared in domestic and foreign markets. The most critical performance of anti-drowning alarm equipment lies in the accuracy of drowning monitoring and alarming, so problems such as missed and false alarms are urgent problems to be solved....

AI Technical Summary

Problems solved by technology

For example, in France and the United States since 2005, a float-type anti-drowning alarm device with a float sensor has appeared. The anti-drowning alarm device has a simple structure and is easy to implement, but the biggest problem is that the false alarm rate is too high

In the past two years, anti-drowning alarm equipment using sound recognition, sonar, water wave air pressure and other probes have appeared in foreign developed countries. Although it has improved the accuracy of drowning monitoring and alarm to a certain extent, its adaptation to the environment is limited. It can only be adapted to small standard swimming pools, with great limitations, and it is difficult to meet the safety indicators set by NF P90-307 and ASTM F-2208 standards
