Coal gangue online recognition and automation selection system based on ARM and CAN bus

摘要

ARM (advanced RISC machines) microcontroller is widely used in lots of fields with characteristics of high-performance, small volume, low power dissipation and low-cost exactly; CAN (controller area network) bus is a bus system. It is especially suited for networking "intelligent" I/O devices. In this paper, it is introduced to explore a new method for the coal dry selection that the coal gangue online recognition and automation selection system based on the newly ARM microcontroller (AT91M40800) and CAN bus (SJA1000) in brief. CPLD technology (EPM7128) is used to modulate time sequence and online update program. Firstly, the digital image processing technology and arithmetic is expatriated in particular. Then the design of the interface circuits is in detail discussed between the ARM microcontroller and the CAN bus, and last the flow diagram of the software is given. Experiments show that the design is successful.
