ABSTRACT：This artic introduced a kind of automation system which according to SCM(Single Chip Micyoco) of pack cannonball to fill the system automatically, the system brief name is ASPC(Automation System of Pack Cannonball). Analyze why want the realization of the method to ASPC to carry on the technique reformation at first, introduce newly ASPC's circuitry, and explained that hardware design and its function. That system with the foundation of calculator controls theories, take 8051 SCM of the seriates MCS-51s as the core, and in addition input and output electric circuit; the main circuitry power switch is IGBT, and IGBT drives the homologous electricity component.
Early ASPC formed with electric appliances, because of its line form, have no in general use and vivid, then it cannot be modified after craft request sued, and cannot making systematic production, burn easily also and easily bad touch the point, result in switch's action not dependable, maintain inconvenient etc., so carry on the reformation is important.
New ASPC used 8051 chipsets of SCM of seriates MCS-51s. it retrenched many electric appliances of early ASPC, and used software to control its functions; this is a creative design. The result of experiment proves that the design contain stronger control result and stronger function.
