Abstract


From the midterm of 1990s to 2005, many industries working mainly with easy vertical retorts have developed quickly in Erdos, Datong and other areas and these industries have had a certain business scale. However, because of the lower level of the equipment and the short of throughput, these industries have wasted much energy and produced much air pollution. As our country has changed the policy for the industry, the new ones will take the place of the old ones.In the past, workers had to be present to manage and operate the equipment. In this way we not only wasted much manpower but did bad to the production safety. With the emergence of the large-scale vertical retort, it couldn’t operate by men, because of it s complex process, lots of equipment and wild distribution. So auto or semi-automatic control system must be applicated in the whole process.The essay introduces the processes of large-scale vertical retort and designs an advanced and useful auto-control system for producing. This system adapts ECS-100 as hardware, uses Advanrol software to monitor the whole process, adjust the parameter, control the interlocking process, diagnose the fault, analyze the trend.After a short time of experiment, we have found the following advantages: stable working system, advanced controlling ways, easy operating, investing less money and so on. The whole system has reached the automation and lowered the working time for the workers, improved the working efficiency, got the satisfied effort.
