Automatic multi-user system for localization, alarm and personal emergency, operating in multi-standard mode in aquatic environment

摘要

The present invention relates to an automatic system for localization, alarm and personal emergency, in aquatic environment operating in multi-standard mode, wherein the system comprises a remote control base and a remote sensing unit, wherein the sensing unit comprises a GPRS/GSM modem (with a SIM card), a WiFi modem (standard 802.11) and a WiMAX modem (standard 802.16) and wherein the sensing unit is waterproof.;The present invention also relates to a method for the use of the above defined automatic system, wherein the sensing unit measures at regular intervals the position and the other parameters related to the sensor(s) present in the unit, and transmits these data to a central unit which is connected to the sensing unit through a WEB connection established through the GSM-GPRS/EDGE network, but also, in the absence of this signal, through other available communication network, such as UMTS, WiFi and WiMAX; wherein the central unit is programmed in such a way that, when the values of the measured parameters overcome a threshold value, an alarm is activated.
