       BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING 
         [0006]    The present invention will be understood and appreciated more fully from the following detailed description, taken in conjunction with the drawing in which 
           [0007]      FIG. 1  is a schematic description of the framework within which the present invention is implemented. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0008]    In accordance with some embodiments of the present invention, a communications network communicates wirelessly to control the opening, closing and locking of secure delivery/intake valves permitting only authorized fueling transactions. Secure valves are installed in several places, typically on the fueling truck inlets and outlets, and underground fuel tank inlets. These valves are opened only by electronic permission occurring when a set of predefined circumstances are present, thus ensuring fuel is accounted for and delivered correctly. These actions are monitored on a computer system installed in each truck in conjunction with a GPS locating system, typically also with a fuel gauging system, a wireless identification protocol, functioning together as the pipe connect system. The computer system is able to issue reports on all fueling activities, including time, location and quantities. 
         [0009]    The process for securing the entire chain of fuel delivery from the producer to the consumer against fuel theft, errors in fueling and retail fuel purchases from unauthorized fuel wholesalers consists of three stages: 
         [0010]    1) loading fueling trucks at the fuel depot/terminal; 
         [0011]    2) transporting the fuel; 
         [0012]    3) delivering the fuel to the fueling stations. 
         [0013]    A detailed description of each stage is described below in conjunction with  FIG. 1 . 
       Loading Fueling Trucks at the Fuel Depot Terminal 
       [0014]    In accordance with the present invention, a communications network is involved in the administration, control and monitoring of the delivery of the fuel from the fuel depot/terminal to the fuel delivery truck and ensures that only fuel that is authorized is dispensed from the fuel depot/terminal. In accordance with some embodiments of the present invention a delivery plan is dispatched to the fuel delivery truck&#39;s on-board computer. The fuel delivery truck (FDT)  40 , further includes one or more electromechanical valves  42  which are disposed at the fueling inlet of FDT  40 . The FDT further includes a geographic location GPS system  44 . The inlet valves are opened at the fueling depot or terminal  60  only by an electronic permission received from the FDT onboard computer  48 , where it is generated only upon fulfillment of the following conditions: 
         [0015]    a) FDT&#39;s GPS system  44  sends a location information to FDT&#39;s onboard computer  48  that the FDT is located in the depot area. 
         [0016]    b) Transceiver unit  50 , also installed on FDT  40 , communicates with transceiver  52  installed on the fueling pipe  54  of fuel terminal/depot  60 . The communication between these two transceivers is to confirm that the electromechanical inlet valve  42  and fueling pipe  54  are in close proximity, preferably up to 5 centimeters. Such confirmation realized, transceiver  50  sends a message to computer  48  notifying accordingly. 
         [0017]    c) Terminal  60  communicates wirelessly with FDT&#39;s onboard computer  48  and verifies proper connection (for example that the FDT is authorized to pipe fuel from the fuel depot) of the fuel pipe to the truck&#39;s inlet valve. 
         [0018]    Only with these three conditions fulfilled will FDT&#39;s inlet valve  42  open. With the valve open, depot/terminal computer  62  can issue a fueling directive and permit fueling. The terminal may also issue, by way of its own computer  62 , a permit to pipe valve  64  to open. After the FDT is loaded with fuel, valve  42  on board the truck is securely locked and cannot be reopened without a predefined electronic signature. All fuel delivered to the FDT and its destination is registered on the truck&#39;s onboard computer  48 . A fuel level gauge monitors fuel level in the fueling truck. This information is transmitted to the system controller and is used to ensure that there is no unauthorized withdrawal of fuel from the tanks, as by making a hole in the fuel tank. 
       Transporting the Fuel 
       [0019]    As the FDT leaves depot/terminal  60 , its activities can be monitored by central fueling site  70  which communicates wirelessly with FDT&#39;s GPS system  44 . The wireless communication between the FDT  40  and central fueling control office (CFCO)  70  is designated by dashed double headed arrow  72 . In accordance with some embodiments of the present invention, the CFCO  70  continuously monitors the quantity of fuel within the truck, also automatically accounting for volume increases and decreases due to density changes as measured, in addition to other physical changes that may occur. Because the electromechanical valves of the FDT are locked electronically, and the onboard computer  48  is notified of any change in volume and status of the fuel, no access to the load of fuel is permitted without a pre-established electronic signature, making the system substantially secure as regards fuel theft, errors in fueling and retail fuel purchases from unauthorized fuel wholesalers. 
       Delivering the Fuel to the Fueling Stations 
       [0020]    CFCO  70  controls and monitors the delivery of the fuel from FDT  40  to the underground tanks of fueling station  84  and ensures that only authorized fuel, in the correct quantities and grade, is dispensed from FDT  40  to the correct underground tank. A fuel level gauge in the tank confirms that fuel loaded on the FDT is actually delivered to the tank. All gauges are wireless, electronic gauges that transmit fuel level information to appropriate controllers. In addition to the electromechanical outlet valve  46  at the FDT, electromechanical inlet valve  82  is placed at the fuel inlet of the underground tank of fueling station  84 . The outlet valve  46  of the FDT and inlet valve  82  of the underground tank are opened only by an electronic permit issued only upon fulfillment of the following: 
         [0021]    a) The FDT&#39;s GPS system  44  advises the truck&#39;s on-board computer  48  that the truck is located in a correct, authorized fueling station according to the fuel delivery plan received from the authorized source, which can be changed remotely from depot/terminal  60  or CFCO  70 . It should be noted that in some embodiments of the present invention, central station  70  can be located in depot/terminal  60 . 
         [0022]    b) Short range transceiver unit  50  installed on the FDT is disposed near electromechanical outlet valve  46  and communicates with another transceiver  86 , which is installed near the station&#39;s underground tank inlet valve  82 . The transceivers intercommunicate to confirm proximity. 
         [0023]    c) FDT onboard computer  48  directs the FDT&#39;s outlet valves. 
         [0024]    d) Fuel station computer  88  authorizes the underground inlet valve  82  to open. 
         [0025]    e) Fuel station computer  88  communicates with the truck&#39;s onboard computer  48  and verifies proper connection of the FDT&#39;s fuel pipe to the station&#39;s inlet valve. Such a communication event may be effected via a medium range communication network or even via satellite communications network. 
         [0026]    During the fueling process, the truck&#39;s onboard tank gauges the fuel and the underground tank gauge computers calculate the volume of fuel dispensed, accounting for volume adjustments necessitated by density changes. 
         [0027]    Upon completion of the fueling process, the valves are again locked, preventing unauthorized access to the fuel. The fuel depot/terminal is immediately notified of the quantity and grade of fuel delivered. 
       Fuel Consumption Monitoring and Administration by a Consumer Vehicle in the Refueling Station 
       [0028]    As a vehicle  90  approaches the refueling station, a vehicle smart tag (VST)  92 , which is installed thereon, preferably on the vehicle windshield, communicates with the communication unit installed in the refueling station  84  sending the information collected since the last refueling. The VST supplies the secure identification information about the vehicle, its engine hours, location data (GPS data), odometer reading, speed reading, driver behavior (harsh breaking and acceleration). Authorization to fuel is granted subject to the presence of a smart tag  94  that is installed around or next to the fueling inlet of the vehicle. In some cases authorization to fuel is granted subject to presentation by the driver of a handheld smart card  96  used to identify the driver in the fueling process. With the nozzle inserted into the fuel inlet, a reader  98  installed on the fueling nozzle becomes close enough to communicate with the communications tag element  94  near the vehicle fuel inlet. The data from the tag  94  next to the refueling inlet is sent via the communication unit installed on the refueling station to the office station  70 , and if the data matches the data of the VST installed on the vehicle, authorization to fuel is granted. Removing the nozzle from the fuel inlet will break the communication between the nozzle reader which is installed on the fueling nozzle, and the tag on the vehicle tank near the fueling inlet, immediately stopping the flow of fuel. This measures the correct grade of fuel pumped to the correct vehicle by the correct driver. 
         [0029]    Another feature of the invention is that the system can ensure that the fuel that is registered by the fuel pump as going out from the fuel pump to the vehicle is equal to the fuel actually getting out of the fuel tank at the station and equal to the fuel received by the vehicle. This is done by installing at the vehicle a unit that electronically connects to the fuel tank via the CAN BUS or OBDII or directly to a gauge on the vehicle fuel pump or to the car installed fuel gauge. The pump is monitored by an electronic measuring device that connects to the pump head or directly to the pump pulser. All of these features permit the system to check and verify fuel use and dispensing by multiple devices. 
       OTHER FEATURES AND BENEFIT OF THE PRESENT INVENTION 
       [0030]    Another feature of the present invention is that the various valves and controls can be protected from being manually overridden by placing the valves and other sensors in a protective enclosure or dome. The enclosure can be constructed to detect an attempt to mechanically access or manually manipulate the valves. A number of different types of devices can be used for this purpose. The valves can be placed in a vacuum or pressurized chamber, such that a pressure change caused by manual interference causes shutdown and lockdown of all valves that cannot be overridden. An electronic or light controlled interference detector or other such device could also be used. Any controls or measuring devices can be protected in this manner. 
         [0031]    While the controls of this invention are designed to be administered by a computer in accordance with programmed instructions and data input from the various components of the system, the system also can be set up so that the approval of an individual operator is necessary for fuel transfer operation. 
         [0032]    The system implemented in accordance with the present invention addresses the significant problems experienced by the major participants in the fueling industry. Depot/terminal operators want to increase their control over the fuel delivery process, eliminate fuel theft and fuel degradation, and ensure the correct amount and grade of fuel is properly delivered to the correct service station safely. Oil companies want to maintain and increase customer loyalty and profits. Home base operators need to control mobile fueling and in-house fueling facilities and fleet owners want to eliminate fraud committed by drivers and depot operators and gain real time control over their fleet vehicle. 
         [0033]    While all of the features of the present invention can be advantageously be used together to provide a comprehensive monitoring and control system, it is not required that all elements be used together. Benefits are obtained by the use of each feature individually.
