Abstract
This article used programmable controller PLC to realize the washer completely automatic control, explained the PLC control principle method, the characteristic and controlled the washer the characteristic. The article during introduction washer structure, carries on the analysis to the completely automatic washer control system, proposed in this foundation based on the PLC completely automatic washer control plan, and has carried on the proof to the plan, has carried on the design according to the washer principle of work to the procedure and the flow, has the intellectualized degree high, safe reliable and so on the characteristics. To the button, the relay, the switch, the frequency changer and so on other some I/O spot carries on the control, realized the washer to wash clothes the process automation. Because spreads every time lavation, draining water, dehydrated time by PLC in counter control, so long as therefore the change counter parameter may change the time.
Keywords: Programmable Logic Controller; The automatic process; converter; control relay
