conversion chart
1.Based on 80C196KC single-chip microprocessor AC sample system, this paper especially analyses various factors that influence the precision of Half-cycle Fournier Arithmetic, makes improvement on many ways such as arithmetic ,frequency measure, sample step partition, sample synchronization, A/D conversion, anti-jamming and parameter calculation, and finally provides applied hardware chart and software flow chart.
2.Aiming at the existence of coal dust and gas in the coalmine environment and the special requirements of mine case explosion-proof surface process, the error conversion model, shape precision characteristics, transfer drawings, descriptive equation and error transfer structure chart in the production technological process of case accessories adopting the information flowchart of control theory are discussed, which simplify the traditional block diagram of technological process and represent the relationship of working procedure (variable) by information flowchart instead of miscellaneous block diagram.
