With development of mechanical and electronic technology, mechanical automation technology plays an
important role in many areas. Because of high demand for food safety, mechanical automation technology in food factory
is used widely. But there still is gap with advanced countries, mainly in automation software design. Through designing
the automation monitoring system of food packaging production line, general process of automation control software
design is introduced. And the results shows current machines are potential to work automatically and efficiently and
produce goods with low lost and high quality.
