摘要:
A motorized shade control system includes electronic drive units (EDUs) having programmable control units directing a motor to move an associated shade in response to command signals directed to the control units from wall-mounted keypad controllers or from alternate devices or control systems connected to a contact closure interface (CCI). Each of the EDUs, keypad controllers and CCIs of the system is connected to a common communication bus. The system provides for initiation of soft addressing of the system components from any keypad controller, CCI or EDU. The system also provides for setting of EDU limit positions and assignment of EDUs to keypad controllers from the keypad controllers or CCIs. The system may also include infrared receivers for receiving infrared command signals from an infrared transmitter.

A control system includes a processor transmitting signals to a shade network and a lighting system directing that motorized shades and dimmable loads be set to desired intensity levels. A communication interface having a buffer is connected between the processor and the shade network. The communication interface provides for communication with the processor based on streaming protocol and with the shade network based on event-based protocol. The shade network converts intensity levels into shade positions. The processor may direct the shade network to move a shade in a series of substantially equal steps to simulate a relatively slowly moving shade. The processor may be connected to a timing device for creating a program based on time-based shade position information for directing the shades to be moved to given positions at certain times of day. A computer running user interface software may be be connected to the system to facilitate programming.

Calibration of a motorized roller shade is accomplished by calculating a radius of a roller tube and thickness of a shade fabric rotatably supported by the roller tube. First, a lower edge of the shade fabric is moved to a first position at a first linear distance from a predetermined position. Second, a first number of revolutions of the roller tube between the first position and the predetermined position is determined. Next, the lower edge of the shade fabric is moved to a second position at a second linear distance from the predetermined position and a second number of revolutions between the second position and the predetermined position is determined. Finally, the tube radius and the fabric thickness are calculated from the first and second linear distances and the first and second numbers of revolutions. The tube radius and the fabric thickness are used to control the linear speed of the lower edge of the shade fabric.

The present invention provides a method of assigning a unique device address to a remotely-located control device in a wireless lighting control system having a plurality of control devices. Each of the control devices is operable to couple to a source of power and to be assigned a unique device address. The method first comprises cycling power to the remotely-located control devices, i.e., interrupting and restoring power to the control devices. The control device transmits wirelessly a signal uniquely identifying the control device within a predetermined amount of time after the cycling of power. A list of unaddressed control devices that have recently been power cycled is generated. Each of the control devices on the list is then assigned and transmitted a unique device address.

The method of the present invention allows a first wireless control device that is operable to communicate on a predetermined one of a plurality of channels to establish communication with a second wireless control device that may be communicating on any of the plurality of channels. A beacon message is first transmitted repeatedly by the wireless control device on the predetermined channel. The second wireless control device listens for the beacon message for a predetermined amount of time on each of the plurality of channels. When the second control device receives the beacon message on the predetermined channel, the second control device begins communicating on the predetermined channel. The second wireless device may begin listening for the beacon message in response to powering up.
摘要:
A load control system comprises a plurality of control devices, each coupled to one of a plurality of device communication links. The device communication links are each coupled to a one of a plurality of link power supplies, which provides power for the control devices on the device communication links. The link power supplies are coupled together via a repeater communication link and operate as repeater devices to retransmit digital messages received from the device communication link onto the repeater communication link, and vice versa. The retransmitted digital messages are substantially the same as the received digital messages. No control devices are coupled to the repeater communication link, such that no control devices draw current through the repeater communication link. A maximum of only two or three link power supplies are coupled between any two control devices of the load control system.

The present invention provides a method of discovering a remotely-located control device in a wireless control system having a plurality of control devices. Each of the control devices of the control system has a unique serial number. A query message is first transmitted to the plurality of control devices. An acknowledgement message is transmitted from the first control device in response to the query message. The acknowledgement message is transmitted in a random transmission slot and contains a random data byte. The first control device is identified by the random transmission slot and the random data byte. The serial number of the first control device is requested, and transmitted from the first control device. At this time, the control device is operable to be assigned a unique device address.
摘要:
A radio-frequency (RF) load control system includes both two-way and one-way (e.g., transmit-only) remote control devices, and provides a simple, reliable process for configuring the one-way devices into the system. The one-way device may be programmed to operate at one of a predetermined number of radio frequencies as part of a frequency-selection procedure, during which, the one-way device transmits a test command to a signal repeater of the system. If the test command is transmitted at the same frequency as the repeater, the repeater emits an audible beep to inform the user that the remote control is transmitting at the appropriate frequency. To associate the two-way devices with the system, the signal repeater streams an “enter address mode” command. To allow the one-way device to be associated with the system, the signal repeater pauses the transmission of the enter address mode command to allow the one-way device to transmit an activation request message to the signal repeater.
