Block Diagram of the VIMS Loader Payload System | |
The VIMS Loader Payload System (VIMS/LPS) is used on the large wheel loaders. The Loader Payload System is a subsystem of the standard VIMS. The keypad is used by the operator to interface with the system. Menus and functions are displayed on the message center of the payload system . The main module receives lift cylinder pressure information over the CAT data link. The main module receives lift cylinder position information over the CAT data link. Additional hardware is a “Payload Store” button and an optional printer in the cab.
The Payload System records the following: date, time, payload of individual buckets, total payload, number of passes and identification of the materials and the trucks. The system can provide information of 1,500 truck loads. VIMS PC® generates the following reports:
- Average time to load
- Average loading time versus type of material
- List of materials
- List of the customers and the vehicles
- Number of trucks by hour
- Number of trucks by material
- Payload of the bucket
- Time between truck loads
- Summary of the materials
- Payload distribution of trucks by customer
The VIMS/LPS configurations are flashed to the onboard system from the service tool through a standard VIMS RS-232 interface. The standard VIMS RS-232 off board systems interface will also be used to download machine productivity information to the Service Tool (laptop computer) for later analysis.
Note: The printer and broadcast interfaces share an output from the VIMS main module. This one output will have a port for a printer and a port for the broadcast interfaces. Information System Builder is used to configure this port in the VIMS configuration software. Only one of the functions will be active, because both functions cannot be supported simultaneously.
