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, wherein the infrared wavelength wireless communication does not include operational control commands associated with the radio wavelength wireless communication and such that operation of the ground compaction device is allowed to continue in accordance with instructions received via the radio wavelength wireless communication during interference for a selected duration of the infrared wavelength wireless communication and operation can be suspended as a function of a status of the infrared wavelength wireless communication and the suspension of the operation is dynamically responsive to control commands received upon interference of the infrared 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.

8. A ground compaction system comprising:
-
a ground treatment device; a hand-held controller configured to wirelessly communicate with the ground treatment device via both a first wireless communication interface and a second wireless communication interface; the first wireless communication interface being configured to communicate omni-directional long range frequency signals between the hand-held controller and the ground treatment device, the omni-directional long range signals manipulating operating functions associated with use of the ground treatment device; and the second wireless communication interface being configured to communicate signals at a different frequency and within a range associated with communication via the omni-directional long range frequency signals between the hand-held controller and the ground treatment device to allow operation of the ground treatment device according to instructions received only via the first wireless communication interface within the range associated with communication via the first wireless communication interface and the second wireless communication device and suspend operation of the ground treatment device due to interruption of the second wireless communication interface; and
the suspension is a function of the operating instructions received via the first wireless communication interface upon interruption of the signal associated with the second wireless communication interface. - View Dependent Claims (9, 10, 11, 12, 13, 14)
