Study on the Proceeding Controller for Automatic Gas Burning Machines

This paper focuses on a G series proceeding controller for the two-stage gas combustion of gas burning machines. This controller, which uses 89C51 microprocessor as the control core, has been produced in small numbers. Based on further analysis of this series of gas burning machines, electronic control proceeding controller, instead of electromechanical proceeding controller, was adopted. The hardware structural drawing, the interface circuit and the main program flow diagram of its software were presented. Corresponding anti-jamming measures against possible interferences were put forward. The result indicated that the electronic proceeding controller was not only technically feasible, but also reduced the cost of production. This will help enhance the market competitiveness of gas burning machines.
