All pressure information can be transmitted in sequence. When the number of the pressure sensors 11 is relatively large, the simultaneous transmission of all the pressure information requires a large-area circuit and a high calculation cost. Therefore, in the present embodiment, all the pressure information is sequentially transmitted.

Specifically, the pulse signal collecting apparatus 100 further includes a plurality of analog switches 13 and switching circuits 14, each of which corresponds to a part of the pressure sensors 111 of the total pressure sensors 111, and the partial pressure sensors 111 may refer to a plurality of One, if each analog switch 13 corresponds to a plurality of pressure sensors 111, the number of analog switches 13 is smaller than the number of pressure sensors 111; if each analog switch 13 corresponds to one pressure sensor 111, the number of analog switches 13 is equal to the pressure sensor 111 quantity.
