Abstract

A wireless switch assembly, comprising: a wireless switch comprising a control switch; a wireless transmitter connected to the control switch and transmitting a corresponding control signal according to the instruction of the control switch; a first identification card pluggably mounted in the wireless switch and connected to the wireless transmitter; a wireless receiver connected to a controller of a controlled piece and communicating with the wireless switch through radio frequency signal or optical signal. The wireless receiver has a second identification card pluggably mounted therein. The present invention can achieve a remote control by a low power consumption wireless transceiver module and matches the wireless switch to the wireless receiver via the identification cards, thus eliminating the need for complicated control wiring, therefore greatly reducing the complexity of wiring, saving electric wires and cables, and reducing cost.

Claims

1. A relay forwarding control system, comprising:

a first wireless control device, controlling a first controlled electricity component, having a first receiving identity code and a first transmitting identity code, and configured to control the first controlled electricity component according to a control instruction after a matched control instruction is received according to the first receiving identity code and to forward the control instruction to a next hop wireless control device according to the first transmitting identity code; and

a plurality of wireless relay control devices, each controlling one controlled electricity component, and each having a corresponding receiving identity code and a corresponding transmitting identity code, wherein the receiving identity code of each wireless relay control device matches the transmitting identity code of a previous hop wireless control device, the transmitting identity code of the each wireless relay control device matches the receiving identity code of a next hop wireless control device, and each wireless relay control device is configured to control a corresponding controlled electricity component according to a control instruction after the control instruction matching the receiving identity code of each wireless relay control device is received and to forward the control instruction to a next hop wireless control device according to the transmitting identity code of each wireless relay control device, in which the next hop wireless control device is at a predetermined distance from the previous hop wireless control device.

2. The relay forwarding control system according to claim 1, wherein each wireless relay control device forwards the control instruction to the next hop wireless control device according to the transmitting identity code of each wireless relay control device after a predetermined time is exceeded.

3. The relay forwarding control system according to claim 1, wherein:

each wireless control device has an IC memory card slot or a chip socket and an IC memory card or a memory chip matching the IC memory card slot or the chip socket, in which a corresponding receiving identity code and a corresponding transmitting identity code are set in the IC memory card or the memory chip, and the IC memory card or the memory chip is field programmable;

or

each wireless control device comprises a wireless receiving and transmitting chip comprising field programmable memory.

4. The relay forwarding control system according to claim 3, wherein a receiving wireless channel assignment code and/or a transmitting wireless channel assignment code are also set in the IC memory card, the memory chip or the wireless receiving and transmitting chip, and each wireless control device transmits and/or receives the control instruction according to a wireless channel assigned according to the receiving wireless channel assignment code and/or the transmitting wireless channel assignment code.

5. The relay forwarding control system according to claim 3, wherein a check code is also set in the IC memory card, the memory chip or the wireless receiving and transmitting chip, each wireless control device determines whether the received transmitting identity code of the previous hop wireless control device is correct, and if not, each wireless control device sends a failure feedback to the previous hop wireless control device or requires the previous hop wireless control device to retransmit.

6. The relay forwarding control system according to claim 3, wherein each wireless control device further comprises a state detection module and has an independent identification, and the state detection module is configured to detect a state of a controlled electricity component and to feed a detection result and the independent identification back to the previous hop wireless control device.
