Industrial control computer (IPC)-based cigarette making machine tobacco rod weight control and quality detection integrated device and method

The invention relates to the technical field of tobacco industry industrial process control and on-line detection and discloses an industrial control computer (IPC)-based cigarette making machine tobacco rod weight control and quality detection integrated device and method. The device utilizes an IPC system and its module and an EtherCAT bus to realize tobacco rod weight control and quality detection on a platform, and comprises a data processing unit, a weight control unit IO module, a quality detection unit IO module, a presignal processing unit, a gas source stabilization unit, a human-computer interface and a communication unit. The weight control unit IO module and the quality detection unit IO module acquire tobacco rod weight control and quality detection related data. The EtherCAT bus protocol is transmitted to the data processing unit. The data processing unit carries out operation on the data and transmits the result to the weight control unit IO module and the quality detection unit IO module, and the data is output. The device is free of a self-researched circuit board and is convenient for maintenance. The device improves tobacco rod weight short period standard deviation technology indexes and reduces tobacco rod removal error rate and removal missing rate. The device realizes weight control and quality detection in one unit and has good cooperativity.
