Concrete acoustic emission damage recognition device based on Internet of Things technology

The invention relates to the technical field of acoustic emission damage recognition devices, and especially relates to a concrete acoustic emission damage recognition device based on the Internet of Things technology. The device comprises a control box, a door cover is arranged on one side of the control box, a supporting rod is fixedly connected to the door cover, a positioning table is arranged at one end of the supporting rod, and a hinge ball is arranged in the positioning table. The hinge ball is fixed on the supporting rod, the door cover is annularly provided with a plurality of uniformly distributed clamping blocks, and one ends of the clamping blocks extend into the control box. By means of the structural design, convenient and fast acoustic emission detection work is achieved, namely, a worker can put the recognition device on one side of a wall to be detected, and stable detection work can be kept. In addition, a worker can hold the supporting rod by hand and control the multiple supporting rods t
