Survival system / Survival system

The bracelets wore by the swimmers have wireless radios. Once there is an emergency, the swimmer just needs to try his best to drag the bracelet, and the bracelet will transmit a signal when suffering a shock, which will be in response by the infrared sensor and get the drowning person positioned. In this way, the lifeguard can easily position the drowning person and save him or her in time, and that can reduce the number of casualties.
