Claim 0:
1. A pneumatic identification apparatus for human body weight of a seat occupant, comprising a control unit and at least one sensing apparatus, wherein the at least one sensing apparatus each comprises a pneumatic sensing apparatus and an auxiliary sensing apparatus;
the pneumatic sensing apparatus comprises at least one soft elastic hollow structure body with an intermediate air space structure and a sensing unit; the sensing unit comprises a first air pressure sensor; and the soft elastic hollow structure body communicates with the first air pressure sensor wherein the first air pressure sensor is configured to detect a first air pressure value Pa in the soft elastic hollow structure body;
the auxiliary sensing apparatus comprises a top pressure-bearing plate and a bottom carrying plate, wherein the top pressure-bearing plate is provided on an upper end surface of the soft elastic hollow structure body, and the bottom carrying plate is provided at a lower end surface of the soft elastic hollow structure body; and
an input end of the control unit is connected to an output end of the first air pressure sensor, and an output end of the control unit is connected to an external communication;
and the control unit is configured to acquire the first air pressure value Pa, compare the first air pressure value Pa with standard set values, and correspondingly output a human body weight type to the external communication.
