The invention relates to the field of information technologies and
automation and discloses a
data acquisition and application snapshot method of a filling
station. The method comprises the following steps of performing second-level sampling on
oil tank information and storing into an
oil tank information base and a real-
time information base, performing second-level real-time oil outlet information on an oil gun, and storing into an oil gun information base and the real-
time information base, acquiring oil gun transaction information and storing into a transaction information base, a transaction snapshot information base and the real-
time information base, acquiring oil gun and
oil tank information at regular time and storing in a history snapshot information base, judging whether an alarm condition is met, judging whether oil tank stock reaches an oil
discharge standard, calculating whether a variation of oil reserve of the oil tank meets a condition, and extracting data from the oil tank information base, the transaction information base and the transaction snapshot information base for loss calculation. The method can simplify business operation, improves working efficiency, monitors and eliminates potential safety hazards in real time, provides a high-efficiency oil
discharge mechanism, automatically applies delivery, performs oil
discharge statistics, and greatly reduces the data size of transmission and storage.
