Abstract

A control system includes an enclosure, a control panel, and a plurality of controls, indicators, or both mounted on the control panel or in the enclosure. At least some of the plurality of controls, indicators, or both are configured to wirelessly communicate with each other inside the enclosure, and at least some controls including wirelessly controlled relays are configured to control devices outside the enclosure. Also, the wirelessly configured controls, indicators, or both are further configured to communicate with a plurality of other controls, indicators, or both in the control system.

Claims

1. A control system comprising:

an enclosure;

a control panel;

a plurality of controls, indicators, or both mounted on said control panel or in said enclosure; and

a plurality of wireless communication units each comprising at least one of a wireless transmitter, a wireless receiver, and a wireless transceiver, each said wireless communication unit electrically responsive to and in close proximity with a corresponding one of said plurality of controls, indicators, or both to enable said plurality of controls, indicators, or both to wirelessly communicate directly with each other inside said enclosure,

wherein a first one of said plurality of controls, indicators, or both comprises a relay that changes state upon receipt of a first wireless signal transmitted by a second one of said plurality of controls, indicators, or both, the change of state controls a device outside said enclosure.

2. A control system in accordance with claim 1 wherein a third one of said plurality of controls, indicators, or both is programmed to wirelessly transmit a second wireless signal to a fourth one of said plurality of controls, indicators, or both, and to transmit a wireless request for an acknowledgement response from said fourth one of said plurality of controls, indicators, or both.

3. A control system in accordance with claim 1 wherein each one of said plurality of controls, indicators, or both is programmed to generate a random address, and further to automatically select a different address in the event of an address conflict with a different one of said plurality of controls, indicators, or both.

4. A control system in accordance with claim 1 wherein said wireless communications include at least one of status checks, control signals, or annunciations.

5. A control system in accordance with claim 1 wherein at least one of said wirelessly configured controls, indicators, or both has a lock-out mode wherein said at least one of said wirelessly configured controls, indicators, or both is not responsive to re-programming.

6. A control system in accordance with claim 5 wherein said lock-out mode is password protected.

7. A control system in accordance with claim 1 further comprising an interface or PC programmed to monitor said plurality of controls, indicators, or both in real time and to provide a status indication for said plurality of controls, indicators, or both.

8. A control system in accordance with claim 7 wherein said interface or PC is programmed to use ID numbers in a data stream to identify each one of said plurality of controls, indicators, or both.

9. A control system in accordance with claim 7 wherein said interface or PC is operable in at least one monitoring mode from the group consisting of status request, last control function performed, active and/or inactive device polling, and error or last detected error.

10. A method for controlling a system comprising:

coupling a control panel and an enclosure;

mounting a plurality of controls, indicators, or both on the control panel or within the enclosure;

mounting a plurality of wireless communication units on the control panel or within the enclosure, each one of the plurality of wireless communication units comprising at least one of a wireless transmitter, a wireless receiver, and a wireless transceiver, each wireless communication unit of the plurality of wireless communication units is electrically responsive to and in close proximity with a corresponding one of the plurality of controls, indicators, or both such that the plurality of controls, indicators, or both may wirelessly communicate directly with each other inside the enclosure;

commanding a first one of the plurality of controls, indicators, or both to transmit a wireless signal;

receiving the wireless signal at a second one of the plurality of controls, indicators, or both, the wireless signal causes a change of state of the second one of the plurality of controls, indicators, or both, the change of state controls a device outside the enclosure.

11. A method in accordance with claim 10 further comprising programming the first one of the plurality of controls, indicators, or both to request an acknowledgement response from the second one of the plurality of controls, indicators, or both.

12. A method in accordance with claim 10 further comprising programming each one of the plurality of controls, indicators, or both to generate a random address, and further to automatically select a different address in the event of an address conflict with a different one of said plurality of controls, indicators, or both.

13. A method in accordance with claim 10 wherein the wireless communications include at least one of status checks, control signals, or annunciations.

14. A method in accordance with claim 10 further comprising setting at least one of the plurality of controls, indicators, or both in a lock-out mode wherein the at least one of the plurality of controls, indicators, or both is not responsive to re-programming.

15. A method in accordance with claim 10 further comprising monitoring the plurality of controls, indicators, or both in real time to provide a status indication for the plurality of controls, indicators, or both.

16. A method in accordance with claim 15 further comprising using ID numbers in a data stream to identify each one of the plurality of controls, indicators, or both.

17. A method in accordance with claim 15 wherein said step of monitoring further comprises using an interface or PC to monitor the plurality of controls, indicators, or both in real time, and configuring the interface or PC in a monitoring mode selected from the group consisting of status request, last control function performed, active and/or inactive device polling, and error or last detected error.
