This paper presents a design method to solve the problems of high failure rate and sorting inefficience in the current cigarette sorting system by integrating RFID technology with CAN BUS. Based on the features of high speed of data transmission, real-time and high reliability, CAN BUS intelligent node is designed. RFID technology enhances the speed and efficiency of cigarette identification. Meanwhile, using the LCD touch-screen and MCGS configuration software, the HMI operation is promoted and the visualization of monitoring processing can also be accomplished.
