Abstract

A system for dispensing fuel at remote locations includes an operations control center and a plurality of remotely located fuel dispensing modules in wireless communication therewith using a telemetry-based communications system. The modules can operate independently of each other and 24-hours a day without the necessity of an on-site attendant and preferably without connection to commercial power and telephone lines. The modules can also operate for weeks or months at a time without being refueled and in remote locations which are subject to severe adverse weather conditions. The operations control center processes information relating to the dispensing of fuel and authorizes the dispensing of fuel at the modules upon receipt of payment information therefrom by generating and transmitting approval information to the modules. A fuel module preferably includes a transportable and multi-compartment housing, an above-ground multi-section fuel tank in the housing and a dispenser for dispensing fuel from the fuel tank upon receipt of payment information from a customer. Motion detectors are also provided to generate a motion-detect signal upon detection of motion external to the module housing, which can indicate the arrival of a customer. A diesel generator and bank of rechargeable batteries are also provided for supplying electrical energy to the dispenser in response to the motion-detect signal. The generator enables each module to function without being connected to commercial power lines from a utility.
