SYSTEM FOR CONTROLLING REMOTE OPERATION OF GROUND WORKING DEVICES
First Claim
1. A system for controlling remote operation of a ground compaction device, the system comprising:
- a hand-held device that remotely communicates with a ground compaction device;
a first transmitter and a first receiver that provide a radio wavelength wireless communication between the hand-held device and the ground compaction device, the radio wavelength communication communicating operational control commands to the ground compaction device from instructions provided by a user associated with the hand-held device; and
a second transmitter and a second receiver that provide an infrared wavelength wireless communication between the hand-held device and the ground compaction device such that operation of the ground compaction device in accordance with instructions received via the radio wavelength wireless communication can be suspended as a function of a status of the infrared wavelength wireless communication.

Abstract
A system for controlling operation of a ground treatment machine includes a hand-held device that wirelessly communicates with the ground treatment machine. The system includes a radio frequency and an infrared frequency wireless communications that are established between the hand-held device and the ground treatment machine. Instructions associated with operation of the machine are communicated to the machine from the hand-held device via the radio frequency communications. A status of the infrared wireless communication is utilized to assess the proximity of the ground working machine relative to the operator and the operating environment such that operation of the machine in accordance with the operational instructions can be interrupted if necessary.
