The invention discloses an unmanned intelligent filling and metering control method for PVC powder. Eight system modules of an information collection system, an incoming identification system, a filling identification initial mining system, a wagon balance metering initial mining system, a filling identification terminal mining system, a filling and metering system, a wagon balance metering finalmining system and a metering verification system are included, operation is conducted according to sequential steps, information collecting is conducted in advance through the information collection system, the incoming identification system identifies judgement, filling task judgement and identification are conducted through the filling identification initial mining system, vehicle information iscollected through the wagon balance metering initial mining system, after filling is conducted through the filling and metering system, the wagon balance metering final mining system is entered, themetering verification system conducts deviation comparison on a difference value of the weight obtained after filling and the net weight obtained before filling, and whether the result is qualified ornot is judged. Accordingly, the purpose of secondary verification of PVC powder filling and metering is achieved, and precision and reliability are achieved; meanwhile, operation is convenient, real-time regulation can be achieved, and ideal production is facilitated, and the purpose of unmanned intelligent filling and metering control is achieved.
