Title:
ELECTRICAL DEVICE REMOTE CONTROL SYSTEM AND SIGNAL RECEPTION CONVERSION TRANSMITTER USED IN THE SAME
Document Type and Number:
Japanese Patent JP2021118474
Kind Code:
A
Abstract:
To remotely control an electrical device installed in a place where infrared signals do not reach, and can easily construct an electrical device remote control system in combination with a commercially available learning remote controller that transmits infrared rays.SOLUTION: An electrical device remote control system according to the present invention includes a learning remote controller 11, a signal reception conversion transmitter 12, and signal reception drive devices 21 and 22. The learning remote controller 11 includes a first operation unit that inputs an operation content for remote control of electrical devices 31 and 32, and an infrared transmission unit that can transmit the operation content as an infrared signal. The signal reception conversion transmitter 12 includes an infrared reception unit that receives an infrared signal, a signal conversion unit that converts the received infrared signal into an FM signal, and an FM transmission unit that transmits the converted FM signal. The signal reception drive devices 21 and 22 each include an FM reception unit that receives the FM signal transmitted by the signal reception conversion transmitter 12, and a drive circuit that drives the electrical devices 31 and 32 on the basis of the FM signal.SELECTED DRAWING: Figure 1
