Smart mat and multi-point detection method for smart mat

A multi-point detection method for a smart mat, comprising:

• providing the smart mat, wherein the smart mat comprises a first surface layer, a second surface layer, a pressure sensing layer, and a detection module, the first surface layer and the second surface layer are disposed opposite to each other, the pressure sensing layer is located between the first surface layer and the second surface layer, the pressure sensing layer comprises a first electrode layer, a conductive layer, and a second electrode layer stacked sequentially, the first electrode layer comprises a plurality of first conductive wires extending along a first direction and spaced apart from each other, the second electrode layer comprises a plurality of second conductive wires extending along a second direction and spaced apart from each other, the first direction intersects the second direction, the conductive layer comprises a plurality of conductive strips extending along the first direction and spaced apart from each other, the plurality of conductive strips correspond to the plurality of first conductive wires in a one-to-one correspondence, and the detection module is respectively connected to the plurality of first conductive wires and the plurality of second conductive wires;
• obtaining a standard electrical signal of a detection point formed between the plurality of first conductive wires and the plurality of second conductive wires by the detection module when the smart mat is not pressed;
• in one detection cycle, inputting a detection signal to one of the plurality of first conductive wires through the detection module, obtaining, through the detection module, one of the plurality of second conductive wires whose electrical signal changes among the plurality of second conductive wires and the one of the plurality of first conductive wires that is input with the detection signal, and when a difference between the standard electrical signal of the detection point formed between the plurality of second conductive wires and the one of the plurality of first conductive wires to which the detection signal is input and the standard electrical signal corresponding to the detection point is greater than a preset value, determining that the standard electrical signal has changed;
• and
• entering a next detection cycle and repeating the steps of a previous detection cycle until all of the plurality of first conductive wires are sequentially input with the detection signal for detection.
