Precision monitoring method for feeding process

The invention discloses a feeding process precision monitoring method. The method comprises the steps of S1, feed liquid weight matching, S2, feed liquid pre-filling, S3, process precision monitoring, S4, tailing precision monitoring, S5, batch precision analysis and the like. According to the feeding process precision monitoring method, error prevention and precision process monitoring are integrated, and process quality accidents of a feeding system can be effectively avoided. Wherein the comparison of the trademark and the weight is carried out from the dimensions of feed liquid distribution, pipeline pre-filling, production, feed liquid recovery and the like, so that the quality accidents of adding wrong materials due to wrong trademark and mixing materials from recovery of the feed liquid to a wrong storage tank are prevented, and the occurrence of wrong addition of the feed liquid is avoided from the source; the two-way closed-loop comparison of theoretical instantaneous precision and real-time precisio
