Title:
METHOD AND DEVICE FOR REMOTE-CONTROLLING SELF-TRAVELING COMPACTING DEVICE
Document Type and Number:
Japanese Patent JP2614402
Kind Code:
B2
Abstract:
PURPOSE: To improve safety in operation by allocating a control beam and a near area beam within a receiving unit by means of an address so as to allocate to a channel respectively prohibited with respect to the other beam.
CONSTITUTION: The receiving unit 11 is provided with an infrared eye A for receiving a beam sent back from diodes D1 to D3. This infrared eye A generates a current corresponding to the received beam. This current is filtered by a frequency filter F to exclude the faulty external line component of a frequency different from the near area beam and a far area beam in a control beam. The current outputted from the frequency filter F reaches a comparator K to inspect the intensity of the received beam cleared in current intensity when the intensity of a beam exceeds a threshold value. A current allowed to pass through operates the IC allocated to the current of IC circuits E1 to E3 by means of an address based on the address included in the current.
