Online detection device and detection method for smoking parameters of smoking machine

The invention belongs to the technical field of cigarette quality characteristic detection, and particularly relates to an online detection device and method for smoking parameters of a smoking machine. The detection device comprises a cigarette sample holder, a trap, a suction module and a control system which are communicated from upstream to downstream, the detection device further comprises a draw resistance module, a first pressure difference detection device and a first pressure difference data acquisition controller. The draw resistance module is connected with the trap in parallel; the first pressure difference detection device is connected to the resistance suction module, and the first pressure difference detection device is used for detecting the pressure difference between the two ends of the resistance suction module in real time and feeding back a real-time pressure difference signal to the first pressure difference data acquisition controller; a relation curve of the pressure difference between
