Abstract

In controlling a line-powered device or appliance remotely, it is known to have a product that provides the user a transmitter and a receiver as a married pair. The transmitter is necessary to send to the receiver a signal that is coded in either software or hardware format. The receiver, upon receiving the transmitted signal, will perform the decoding process. If the received signal is valid, the receiver will respond by switching or performing any variation to the line voltage characteristic that is applied to the appliance.

In this invention, the user can control the appliance remotely via an inventive device without the need to supply the user a dedicated transmitter. This device is a receiver that has an intelligent learning capability.
The user can utilize any of his/her own home entertainment remote control units with his/her choice of command key to program this device. Once programming is completed, the device will and only will respond to the coded signal transmitted by the same key from the same remote control unit that the device has just learned. Hence, the user can assign different command keys to program multiple devices without any concern of interference or false signal recognition. The concept of having the learning feature built into a device to control line-powered appliances remotely without the need for a dedicated transmitter opens up infinite applications to achieve automation for the household (ie, Remote Switched Outlet, Remote Switched Wall-Switch...) regardless to any types of line voltages in the world (i.e., 110VAC, 220VAC...).

Description

214106~
-SPECIFICATION

This inventive idea relates to a new method in controlling any line-powered appliance remotely via a device which acts as a receiver with learning capability. The device is able to learn any key code transmitted by any home entertainment remote control so that once prog~ g is completed, the receiver will become dedicated to respond only to the key code that it has just learned. The receiver will then alter the condition or characteristic of the line voltage that is applied to the appliance accordingly.

Throughout this document, the inventive product will be called Remote Switched Outlet with its abreviation as RSO.

It is common in devices for controlling line-powered appliances/devices remotely that they have to provide the user a ~ "~ er and a receiver. The transmitter and the receiver have to be a married pair.
To avoid false signal recognition, the receiver can only decode the signal transmitted by its own l~n.~ r For controlling many appliances, one ofthe solutions is to have multiple of such married pairs with di~relll coding. The coding can be accomplished by means of hardware or software. Devices of such type are, however, inefficient because it is inconvenient and impractical for the user to carry that many tran~mitters and to decipher the confusion as to which transmitter is for which receiver.

We have found that these disadvantages may be overcome by adding a learning capability to the RSO so that the user can teach the receiver to respond to a specific con"--and transmitted by any infrared remote control. Therefore, there is no need to supply the user a dedicated transmitter. Such method allows the user to make use his/her own remote control not only to control the home entertainment units but also other light fixtures or any other appliances via this inventive RSO. This method lets the user to configure any multi-arrangement to their pr~re. ence.

OPERATION PROCEDURE:

RSO takes all the complicated tasks in itself and leaves the user a simple set of operation as described below:

RefertoFig. 1:

1. Plug the RSO into the wall outlet. By default, "Learning" LED is lit indicating that it is ready to learn.
2. Aim your remote control unit to RSO and press a key of your choice until the "Learning" LED
turns off.
3. Plug the appliance into the RSO's output receptacle.

To turn on or off the appliance, you just aim the remote control to the RSO and press the key that you taught it in step 2. If you want to retrain it with defferent key comm~nd7 press and hold the push button switch of the RSO for approximately 5 seconds until the "Learning" LED is lit, then follow step 2. If you wish to turn on or off the appliance locally, you can simply press the push button switch momentarily (less than 4 seconds.) In drawings which illustrate embodiments of the invention, Figure 1 is a product layout drawing to display the locations of Photo-Sensors, Push Button Switch, "Learning" LED, Input AC Plug and the Switchable Output Receptacle.
Figure 2 is a block diagram of the RSO design to overview the integration of all major circuitries.
Figure 3a: is a detail sçh~m~tic diagram of AC circuit design.
Figure 3b: is a detail schematic diagram of DC circuit design.
Figure 3c: is a detail schematic diagram of INFR~RED DETECTION design.
Figure 3d: is a detail schematic diagram of MICROPROCESSOR circuit.

Figure 2 displays an overview of the major circuitries comprised of a Power Supply, an Infrared amplifier/detector, a microcontroller, a Triac Driver and a Triac. The following is circuit description as to how these circuits function:

AC CIRCUIT: ( Refer to Fig. 3a ) The AC circuit comprises of J2 (an AC input line plug), a Triac Driver U2, a Triac T1, R8, R9, R10, R13, C14, C15 and an AC switched output Jl.
In this design scheme, the ground of J2 is used as a common ground for the entire circuitry and the hot line of the AC is chosen to be the switching line. The switching takes place when MTl and MT2 of the triac are conducted. For the triac Tl to fire and conduct MT1 and MT2, it requires a miniml1m threshold level of 25mA in between the gate and MT 1. For this reason, MAC 1 5A6FP is chosen to handle 400V ~
15 A load maximum with its trigger current no more than IGT=75mA. The triac Tl is required to be triggered by the U2 pin 4 continuously at zero crossing to conduct MTl and MT2. U2 is not only an optocoupler/driver but also a zero crossing device which will fire the Triac only in a region of 9V to 20V.
The MOC3042 is chosen in position of U2. The current is limited by (5v-1.7v)/R11. U2 is turned on 214106~

when PA5 of the micro is going low. The Triac dissipates heat at approx. 1 watt for 1 Amp. of load. The maximum load could go up to 15 Amps which yields 15 watt of power dissipating. Therefore, a heatsink is required. Since the specified triac MAC15A6FP (FP package of T0221C) has an isolated ground case which can be bolted down to the ground plane of the PCB, therefore, heat can be transferred and escaped to the plug of the external appliance. R13 and C14 form a snubber circuit which will slow down the rate of rising and falling current so that the triac will be protected in the event of high voltage surge or kickback current generated from an inductive load.

DC CIRCUIT: ( Refer to Fig. 3b ) The power supply is basically a half wave rectifier accomplished by diode D1. A series capacitor C15 will step the voltage down and limit the power to 2.5w. After rectification, zener diodes D3 re~ tes the voltage at lOV which is filtered by C4. Regulator U6 is required to regulate at 5V which is further filtered by C5. lOV is used for IR circuit and 5V (~ lOmA is used for the microprocessor circuit. During the sleep mode, the micro draws apl)roxil-lately lOOuA awaiting an interrupt. When it is interrupted by S1 or output going low on U1-1, more current will be required.

IN~RARED SIGNAL DETECTION CIRCUIT: ( Refer to Fig. 3c ) IRD1 and IRD2 are the SFH 205 type Silicon Planar PrN Photo-Diode. The signal-to- noise ratio of such photo diode is particularly favorable, even at low ill~lrnin~nces. This type of photodiode is outstanding for low junction capacitance, high cut-offfrequency and short switching times. The photodiode is particularly suitable for IR remote control receiver. IRD1 and IRD2 are reverse-biased by R3. When light strikes, it responses very fast to the changes.

The MC3373 is a spec~ ed high gain amplifier/signal processor bipolar analog IC which provides signal amplification and pulse shaping needed to couple the signal to the microprocessor U3. In the carrier mode setup, the MC3373 acts like an AM receiver subsy$em, amplifying the incoming signal, demod~ ting it, and providing some basic wave shaping of the demodulated envelope. The tuned circuit at Pin 3 provides the main system selectively reducing random noise interference and permitting multichannel operation in the same physical area without falsing. In the multichannel case the carriers must not be ha,l.,ollically related. The bandwidth is determined primarily by C2 and R6 (typically from 30 KHZ to 60 KHZ centering at 40 KHZ). R12 and C6 reduce the gain to stabilize the amplifier. C6 is also a bypass for 40 KHZ frequency. C3 is further filtering out the high frequency noise. C8 also acts as a peak hold capacitor. R1 discharges the peak. R1 and C8 form a RC constant for discharging of envelope detector value.

Pin 14: Tied to COM ground.
Pin 15,16: Associated with X1, C12 and C13 to set clock freguency f=4MHZ.
Pin 1: RESET line is held low at RC constant by R2 and C7.

Pin 6, 7: PA1 and PA2 could be used in the future for additional switches.Pin 4: IRQ active low.
Pin 8: Jumper option; needs to be pulled up if EEPROM is not installed.Pin 3: PB0 serial communication which uses I 2C interface to EEPROM.
Pin 12: PA7 is data line.
Pin 11: PA6 ties to PA5 Pin 9: PA4 provides current sinking for LED1.
Pin 10: PA5 is active low to turn on U2.

EEPROM CIRCUIT:

EEPROM is required to provide memory retension in case of power failure.

-CONTROL WARE

The following is the description of the Control Ware strategy. It is the core design of the inventive RSO.

When the unit is first powered up, The microcontroller will try to load data from the EEPROM. If there is no data present, it will turn on the Learning LED to indicate that it is ready to receive a new command code.

Learnin~ st~Pe: At this stage, the microcontroller is awaiting for an incoming signal. When the user activates a signal by pressing a command key on the remote control. The signal bursts are detected and decoded as a string of TTL level pulses. The microcontroller will take the ratio of these positive going pulses and the negative going pulses. The resultants in hexadecimal value will be stored in the EEPROM.

O~er~tinP st~Pe: From this point on, when there is an interrupt of an incoming signal, the microcontroller will try to decode and process the ratio of the pulses. The resultant value will be compared with the previously stored value. If matched, PAS will go low to turn on the triac driver U2 which in turn, will fire the triac. If unm~tc~ed, it remains at its state and continues to wait for an interrupt.
