FAULT-TOLERANT NON-RANDOM SIGNAL REPEATING SYSTEM FOR BUILDING ELECTRIC CONTROL
An electric control system comprises a plurality of transceivers. The transceivers are also associated with a control for at least one electrical item. A plurality of electric switches provide a wireless signal to a plurality of the transceivers, each being operable to receive the wireless signal, and retransmit the received signal to be received by others of the transceivers. Each of the transceivers is programmed to retransmit a received signal at a distinct period of time after receipt of the original signal.
1 . An electric control system comprising:
a plurality of transceivers, said transceivers also being associated with a control for at least one electrical item;
a plurality of electric switches, said electric switches providing a wireless signal to a plurality of said transceivers, said transceivers each being operable to receive said wireless signal, and retransmit the received signal to be received by others of the transceivers; and
each of said transceivers being programmed to retransmit a received signal at a distinct period of time after receipt of the wireless signal.
2 . The electric control system as set forth in claim 1 , wherein said associated electric items includes a light, and said control providing power to the light.
3 . The electric control system as set forth in claim 1 , wherein a decision is made that a signal is a proper signal if at least two of the received signals are identical.
4 . The electric control system as set forth in claim 3 , wherein if there are at least two of the received signals which come from at least one of the transceivers, then an identification of a proper signal is taken by a vote amongst the received signals.
5 . The electric control system as set forth in claim 1 , wherein said distinct periods of time are determined by a pseudo-random generator.
6 . A method of operating an electric control system comprising the steps of:
providing a wireless signal from a switch to a plurality of said transceivers, receiving said wireless signal, and retransmitting the received signal to be received by others of the transceivers; and
each of said transceivers retransmitting a received signal at a distinct period of time after receipt of the original signal.
7 . The method as set forth in claim 6 , wherein said associated electric items includes a light, and said control providing power to the light.
8 . The method as set forth in claim 6 , wherein a decision is made that a signal is a proper signal if at least two of the received signals are identical.
9 . The method as set forth in claim 8 , wherein if there are at least two of the received signals which are received by at least one of the transceivers, then an identification of a proper signal is taken by a vote amongst the transceivers.
10 . The method as set forth in claim 6 , wherein said distinct periods of time are determined by a pseudo-random generator.
