Fuel supply system and root cause identification program

Abstract

To provide a fuel supply system and a cause identification program that can easily grasp the cause of communication impossibility between a terminal control device and a flowmeter and allow workers to take appropriate actions according to the cause.SOLUTION: A fuel supply system 100 includes a refueling vehicle 1 that includes a flowmeter 12 that measures an amount of fuel supplied to a fuel tank 200, and supplies loaded fuel, and a terminal control device 2 that can communicate with the flowmeter 12 and receives the amount of fuel supplied that is measured by the flowmeter 12. The terminal control device 2 stores a communicable area of the flowmeter 12, acquires position information of the terminal control device 2, and determines a cause of communication impossibility based on the communicable area of the flowmeter 12 and the position information of the terminal control device 2 when communication between the flowmeter 12 and the terminal control device 2 becomes impossible.SELECTED DRAWING: Figure 1
