The liquid crystal display screen of the gas pump is the human-machine interface that records the real-time data of the refueling process at the gas station. If the gas pump suddenly loses power or fails during the refueling process, the display screen of general manufacturers will not be able to display the data, and the previously displayed data will be unknown, resulting in the gas station and the car owner being unable to settle the bill correctly.
