Ground mat type fall-down detection alarm device

The utility model relates to the field of signal acquiring and processing technology and particularly provides a ground mat type fall-down detection alarm device. The alarm device comprises three parts, namely a splicing type pressure detection ground mat with an interface, a human body infrared sensor with an interface, and a gateway. The splicing type pressure detection ground mat comprises a blanket surface and a hub. The blanket surface laid on the ground functions as a pressure sensor and is divided into a plurality of independent small areas. The blanket surface is formed through the spliced type connection and is connected with the hub. The hub is used for detecting the pressure conditions of all the areas of the blanket surface, then summarizing and reporting required data to the gateway. According to the technical scheme of the utility model, compared with the prior art, the ground mat type fall-down detection alarm device is simple and convenient in installation. The pressure splicing type ground ma
