In order to improve the control precision and quality stability of cigarette manufacturing process

a design is presented to implement the physical parameters online testing of cigarette.The measured physical parameters of cigarette include weight

length

circumference

roundness

density

humidity

smoke resistance

ventilation rate.The design includes the system hardware and software from system architecture perspective

and details of software and hardware choices to consider.The design of the system used in Changde Cigarette Factory for the actual testing and application.The test show that the data of various physical parameters for cigarette testing is within the acceptable error range

and realize multi-parameter measurement functions of system.
