770, 772, 773E, 773F, 777E and 777F Off-Highway Trucks and 775F Quarry Truck VIMS Truck Payload System Caterpillar

Onboard Features of the Truck Payload Measurement System (TPMS)

The features that are listed below are the onboard features of the TPMS.

1. Calculate information for the payload cycle and store the information for the payload cycle.

   Time stamp - The "Date/time" that marks the start of the payload cycle.

   Payload - The weight of the material that is being moved

   Loading Time - The amount of time that is required to load the truck

   Stopped Empty Time - The "total time" that is recorded for a truck that is "stopped while empty" during the payload cycle

   Travelling Empty Time - The "total time" that is recorded for a truck that is "traveling while empty" during the payload cycle

   Travel Empty Distance - The "total distance" travelled by the truck while the truck was empty.

   Stopped Loaded Time - This is the time that is recorded when a truck with a full load is not moving during the payload cycle.

   Traveling Loaded Time - This is the time that is recorded when a truck with a full load is moving during the payload cycle.

   Transmission Shifts - This is the total number of transmission shifts "up or down" that were made during the payload cycle.

   Used Fuel - This is the total fuel that is used during the payload cycle.

   ID of the Operator - This is the identification number of the operator that had dumped the load for that payload cycle. The operator must enter this number into the VIMS / TPMS via the Messenger/Advisor keypad module. This identification number may also be used to identify the pit and/or the origin of the load.

2. Calculate resettable totals and store resettable totals.

   1. The total number of loads that were hauled since the "onboard system" was reset last.

   2. The total weight that was hauled since the "onboard system" was reset last.

   3. Total travel distance since the "onboard system" was reset last.

   4. Total travel time since the "onboard system" was reset last.

3. Provide a way to download onboard information to the off-board system for analysis.

4. Provide a way to calibrate the system via the Messenger/Advisor display.

5. Provide a way to configure the system to specific requirements of the user.

   1. Set the maximum payload weight.

   2. Turn on/off last pass indicators.

   3. Turn on/off Maximum Payload Speed Manager.

   4. Set the limits for the events for the Road Analysis Control.

6. Display payload information on the Messenger/Advisormodule as the truck is being loaded.

   1. Payload weight

   2. Loading status messages

7. Display loading status information with the payload status lamps as the truck is being loaded.

   1. Loading

   2. Last pass

   3. Fully loaded

   4. External payload display

8. The following payload information is made available to broadcast:

   1. Loader pass count

   2. Last pass indicator

   3. Cycle data

9. Calculate the parameters (per payload cycle) and then display the parameters that are listed here:

   1. Payload weight

   2. Payload status (“traveling, empty, etc.”)

   3. Haul distance.

10. Automatically adjust for the weight of an empty truck as operating conditions change.

    1. Fuel remaining onboard.

    2. Carryback that is in the body of the truck or carryback that is stuck to the underside of the machine

11. Detect incorrect suspension cylinder charge (collapse) and cause an appropriate event.

Off-Board Features of the TPMS

The features that are listed below are features of VIMSpc.

1. Provide a way to download the data that is stored in the onboard system.

2. Provide a way to calibrate the onboard system.

3. Provide a way to view "onboard payload related information" in real time.

4. Provide a way to later analyze the data that is downloaded from the onboard system:

   1. VIMSpc

   2. VIMS Supervisor

   3. Data may be exported to a commercial spreadsheet of the user's choice.
