Abstract: To improve the quality of the cigarette and meet the requirements of digital management of the equipments in the tobacco enterprises, a real time inspection and control system for the cigarettes production chain was developed. The real time extension function was realized with RTX under the environment of Windows based on the platform of standard PC architecture and commercial off-the shelf I/O hardware. The cigarettes weight control and dense-end position tracking subsystem, online quality inspection subsystem and OPC server were integrated in one system as independent function module. Functions of this system could be reconfigured or extended to meet specific application requirements. The proposed system was applied in the tobacco machinery companies and some tobacco enterprises in China. Application results showed that the real-time inspection & analysis for each cigarette could be realized.
