Gateway-based situation monitoring system

A gateway-based situation monitoring system, the system comprising:

• a plurality of edge sensor terminals each installed in a specific place, connected according to a plurality of wireless communication schemes, and configured to collect life signals generated in the specific place as monitoring information;
• a gateway terminal selectively connected to the plurality of edge sensor terminals according to the plurality of wireless communication schemes, and configured to receive the life signal and transmit the received life signal to a cloud server;
• and
• the cloud server configured to detect an occurrence of an abnormal situation while monitoring the specific place by analyzing the life signal received from the gateway terminal,
• wherein the occurrence of the abnormal situation is predicted probabilistically through a pre-built prediction model constructed by learning a life signal pattern generated by classifying the life signal for each edge sensor terminal of the plurality of edge sensor terminals,
• wherein the gateway terminal is further configured to
• group edge sensor terminals of the plurality of edge sensor terminals employing a same wireless communication scheme in a group corresponding to the same wireless communication scheme so that a plurality of groups corresponding to the plurality of wireless communication schemes are generated,
• allow the plurality of groups formed according to the grouping to independently occupy communication due to the plurality of wireless communication schemes, and
• in an occurrence of an overlapping channel between the plurality of groups, selectively connect wireless communication schemes related to a corresponding overlapped channel by dynamically determining a priority and connection time of a selective connection for each wireless communication scheme of the wireless communication schemes related to the corresponding overlapped channel according to size, average amount of data, or average transmission period of the groups corresponding to the wireless communication schemes related to the corresponding overlapped channel.
