in more detail:
the volumes of the sampling airbag bodies and the detection airbag bodies are known, for example (the sum of the volumes of the detection airbag bodies is 6m, so the volume of the sampling airbag bodies is 2 m);
the detection steps are as follows: firstly, vacuumizing the sampling air bag bodies, the first air supply pipe, the second air supply pipe, the air compressor, the second air supply pipe and the air in the detection air bag bodies through reserved vacuumizing valves, closing valves at the communication positions of a branch pipeline (the air in the branch pipeline can be ignored) and the first air supply pipe, and inflating the inside of the sampling air bag bodies through a one-way valve at the bottom of the sampling tank body until all test lamps at the top of the sampling tank body are lighted (the principle is that wires in each U-shaped wire cavity are electrically connected with the test lamps at the top of the sampling tank body respectively, and power is supplied to each wire through a first motor at the bottom), and as the electric buttons arranged in each main cavity are connected with each wire in series, when the sampling air bag body is filled with air and fills up each main cavity, each electric button is extruded, when each electric button is pressed down by the sampling air bag body, the wires are electrified, the test lamps are lighted), and the inflation is finished;
