NFC cavity, NFC cavity system and method for controlling NFC interaction cavity

The invention relates to the technical field of reaction vessels, in particular to an NFC cavity, an NFC cavity system and a method for controlling an NFC interaction cavity. According to the NFC cavity, the cavity is a polyhedron, at least one surface of the cavity is provided with an NFC control module, the middle of at least one surface of the cavity is provided with a brake, and a connecting strip is arranged along the circumference of the surface with the brake arranged in the middle; the NFC control module is used for controlling opening and closing of a gate; the connecting strip is used for being combined with connecting strips of other NFC cavities to ensure the sealing performance between the cavities. The cavity can be combined with any other same cavity in various ways, a connecting strip for combining the cavities has excellent sealing performance, and when the cavities need to be communicated or isolated, different instructions are directly sent to the NFC control module, the opening and closing
