Wireless remote control system
First Claim
1. A wireless remote control system having a hold-type wireless remote controller and a fixedly mounted main controller,said wireless remote controller comprising:
- clock means for providing a current time;
setting means for setting an operation time of a controlled object;
calculation means for calculating a difference between an operation time set by said setting means and a current time provided by said clock means and outputting the difference as a setting time;
code generating means for generating a first code representative of the setting time calculated by said calculation means and a second code for operating the controlled object; and
transmission means for transmitting the first code when said setting means sets the operation time, and the second code when the current time becomes the operation time; and
said main controller comprising;
reception means for receiving the codes from said transmission means;
timer means which is set by the first code received by said reception means; and
operation means for operating the controlled object if a logical OR condition is satisfied between a first signal indicating that said reception means has received the second code and a second signal indicating that said timer means has timed up.

Abstract
A wireless remote control system has a hold-type wireless remote controller and a fixedly mounted main controller. When the wireless remote controller sets an operation time of a controlled object, it sends to the main controller a first code representative of a setting time corresponding to a difference between the operation time and a current time. Upon reception of the first code, the main controller sets the setting time at its timer. When a current time becomes the operation time, the wireless remote controller transmits a second code for operating the controlled object. If the main controller can receive the second code, the controlled object can be operated in response to the received second code. If on the other hand the main controller cannot receive the second code, the controlled object is operated by a time-up signal of the time in the main controller.
