Design of a Remote Anti-Cheating System for Fuel Dispensers

Cheating problems in fuel dispensers have been a persistent issue for consumers, market supervision, and tax control departments. While many research results have been achieved in preventing cheating, illegal individuals still find new ways to cheat. To further address metering cheating in fuel dispensers, this paper proposes a design method for a remote anti-cheating system that can monitor real-time metering and cumulative operation status. An independently running computer pulse counting device is attached to the fuel dispenser computer motherboard. The wireless data acquisition module uploads the fuel dispenser pulse count, fuel volume, and cumulative volume from the fuel dispenser tax controller's RS232 communication interface to the server. The fuel dispenser pulse equivalent parameters stored on the server side are periodically compared with the fuel dispenser motherboard data. The fuel dispenser is automatically locked if the comparison result exceeds the limit. This system enables market supervision and tax control departments to monitor all data and operation status in real-time remotely. Practical application has shown that the system has low investment cost and strong operability, and can fundamentally monitor cheating behavior in fuel dispensers, preventing metering cheating.
