Abstract

The present invention comprises a system for remote control of garage doors and other devices wherein an extremely large number of codes are available for remote transmitters for operating the garage operator and wherein each transmitter has its own unique and permanent nonuser changeable code. The receiver at the garage door operator is capable of storing and remembering a number of different codes corresponding to different transmitters such that the receiver can be programmed so as to actuated by more than one transmitter code thus allowing two or more transmitters to actuate the same garage door operator and wherein the receiver stores the valid codes for the different transmitters.

CROSS-REFERENCES TO RELATED APPLICATIONS
This application comprises an improvement on application Ser. No. 615,339, filed May 30, 1984, U.S. Pat. No. 4,638,433, in which the inventor is Wayne R. Schindler assigned to the assignee of the present application.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates in general to garage door operators and in particular to a novel garage door operator wherein the receiver can be energized by two or more transmitted codes which are stored in the receiver.
2. Description of the Prior Art
Garage door operators of the prior art used transmitters in which the code can be changed by various methods as, for example, by moving two position switches to change the code. Such systems have also used code changing switches in the receiver so that the receivers can be set to correspond to the selected transmitter code.
It has also been known to use fixed frequency transmitters and fixed frequency receivers such that if the transmitted frequency matches the receiver frequency the receiver will respond.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a plurality of transmitters wherein each transmitter has its own unique and permanent non-user changeable code and wherein the receiver can be placed into a program mode wherein it will receive and store two or more codes corresponding to two different transmitters. The number of codes which can be stored in transmitters can be extremely high as, for example, greater than one million codes. Thus, the invention makes it possible to eliminate the requirements for code selection switches in the transmitters.
In the present invention the decoder module in the receiver will be capable of learning several different transmitted codes which will eliminate code switches in the receiver and also provides for multiple transmitters for actuating the garage opener.
The communication link can be various system such as radio frequency, light, wires, etc.
The invention makes it very easy for the user to operate the system and more secured code systems are available due to the higher number of available codes.
An encoded signal will be utilized wherein a pulse and blank time comprises a sync time base and different link pulses such as 1, 2, 3 or 4 milliseconds can be selected so as to provide different codings. Each datum can be 1, 2, 3 or 4 times the length of the sync pulse. The timing is from the rising edge to rising edges of the pulse and with ten data bits the number of codes can be in excess of one million codes.
In the invention, each transmitter encoder will contain a chip which contains a unique code and the receiver will be able to memorize two or more as, for example, five different transmitter codes. This eliminates the need to have coding switches in either the transmitter or receiver. This eliminates the requirement that the user set the code switches so they match since the code switches are eliminated.
In the invention, during an operate mode, a receiver code must match an already programmed code four times in order to operate the garage door. This match is referred to as a valid code. Each valid code can be separated by up to two error codes and still have the output indicated as accurate.
In the program mode a code must be received four times in a row in order to be permanently stored in the receiver. Any error code will reset the valid code counter.
The advantage of the coding scheme are:
1. Higher peak power without exceeding the FCC rules which gives longer transmitter range.
2. Eliminate code switches in the transmitter and receiver making it easier for a customer to install and operate his garage door operator.
3. Customers having more than one transmitter will not have to match codes.
4. More secure codes due to the higher number of combinations which are available. Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawings although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure and in which:

The garage door operator can also be operated by the transmitters 26 and 28 which have operate transmit buttons 27 and 29, respectively.
As illustrated in FIG. 2 the garage door operator includes a receiver 41 which has a suitable antenna 42 for receiving radio frequency transmissions from the transmitters 26 and 28 and supplies an input to a decoder 43 which provides an output to a microprocessor unit 44. The microprocessor unit 44 is connected to a garage door operator mechanism 46 which includes the motor which drives the chain 15 to move the door 17 in a conventional manner. The control 38 is connected to the microprocessor 44. A pair of switches 22 and 23 are mounted on a switch unit 19 connected to the unit 11 and also to the microprocessor 44. The switch 22 is a two position switch that can be moved between the operate and program positions to establish the "operate" and "program" modes. The switch 23 can be moved to a number of selected positions indicated by the 1 through 5 so as to allow the particular code of a number of different transmitters to be stored in the receiver so that the receiver will respond to such codes.
In the illustrated embodiment, the receiving unit can respond to up to five different transmitters which have five different transmitting codes. FIG. 5 illustrates the code utilized in which the bit times are nominally 0.5 milliseconds for example. The data times are nominally 1, 2, 3 or 4 milliseconds.
The sync pulse is a unit measure of time. Each datum is measured with respect to the sync pulse and each datum can be 1, 2, 3 or 4 times the length of the sync pulse. The timing is from the rising edge to rising edge of adjacent pulses. Using 10 data bits the number of codes which is available is in excess of one million codes.
In the invention, each transmitter such as transmitters 26 and 28 will have a unique code which is determined by the encoder chip contained in the transmitter. The receiver unit will be able to memorize and store a number of different codes as, for example, five different transmitter codes which eliminates the need of coding switches in either the transmitter or receiver which are used in the prior art. This also eliminates the requirement that the user match the transmitter and receiver code switches.
When the garage door operator is initially installed, the switch 22 is moved to the program mode and the energize button 27 of the first transmitter 26 is depressed so that the unique code of the transmitter 26 is transmitted. This is received by the receiver 41 and decoded by the decoder 43 and supplied to the microprocessor unit 44. The switch 23 is placed in the first position, and with the switch 22 in the program mode the code of the transmitter 26 will be supplied to the memory address storage 47 and stored therein. Then if the switch 22 is moved to the operate mode and the transmitter 26 energized by depressing the transmit switch 27, the receiver 41, decoder and the microprocessor 44 will compare the received code with the code of the transmitter 26 stored in the first memory location in the memory address storage 47 and since the stored memory address for the transmitter 26 coincides with the transmitted code of the transmitter 26 the microprocessor 44 will energize the garage door operation mechanism 46 to open or close the door.
In order to store the code of the second transmitter 28 the switch 22 is moved again to the program mode and the switch 23 to the second position and the transmitter 28 is energized by depressing its transmit switch 29. This causes the receiver 41 and decoder 43 to decode the transmitted signal and supply it to the microprocessor 44 which then supplies the coded signal of the transmitter 28 to the memory address storage 47 where it is stored in a second address storage location. Then the switch 22 is moved to the operate position and when either of the transmitters 26 and 28 are energized, the receiver 41 decoder 43 and microprocessor 44 will energize the garage door operation mechanism 46 to cause the door to either move up or down depending upon its initial position. Thus, the codes of the transmitters 26 and 28 are transmitted and stored in the memory address storage 47 during the program mode after which the garage door operation mechanism will respond to either of the transmitters 26 and 28. Any desired number of transmitters can be programmed to operate the garage door mechanism as, for example, up to five transmitters can be programmed into the memory address storage 47 by using the program switch 22 and the selector switch 23.
This invention eliminates the requirement that binary switches be set in the transmitter or receiver as is done in systems of the prior art to establish a code to which the receiver will respond and the invention also allows a garage door operator to respond to a number of different transmitters because the specific codes of a number of the transmitters is stored and retained in the memory address storage 47 of this unit.
FIGS. 3 and 4 comprise the flow chart which describe both the operate and program modes of the invention. Basically, in the operate mode, a received code must match a program which has already been programmed and for four times so as to operate the garage door. This match is referred to as a valid code in the flow chart. Each valid code can be separated by up to two error codes and still have the output actuate. For example, a code of valid-error-error-valid-valid-valid would actuate the door. On the other hand, a code of valid-valid-valid-error-error-error-valid would not actuate the door.
In the program mode a code must be received four times in a row in order to be permanently stored. Any error code will reset the valid code counter.
with reference to the flow diagrams of FIGS. 3 and 4 if it be assumed initially that the switch 22 is in the operate position an incoming signal will be supplied to terminal A in FIG. 3 and an output will be supplied to terminal B which indicates that the switch 22 is not in the program mode but in the operate mode. Terminal B is illustrated in FIG. 4 and the microprocessor compares the incoming code with any codes in the five code locations stored in the memory address storage 47. If these codes match then the error counter is cleared and all other valid counters. If the valid counter receives the code four times than output is supplied to the terminal C which operates the garage door operator. If the valid counter for the code equals less than 4, then the valid code counter is incremented until the valid code counter does not equal 4 which actuates the proper output. Relative to FIG. 4 if the input code does not match any of the five stored codes, then the error counter is incremented and when the error counter equal 3 the error counter is cleared and all valid counters are cleared.
If the switch 22 is in the program mode as shown in FIG. 3 when the incoming signal from a transmitter is received, the flow diagram is followed so as to store the new incoming program in the code location pointed to by the code location pointer 23. It is to be noted that up to five addresses can be stored in the system of the invention.
It is seen that the present invention allows a receiving system to respond to one of a plurality of transmitters which have different unique codes which can be stored in the receiver during a program mode. Each time the "program mode switch" 22 is moved to the program position, a different storage area as determined by the switch 23 can be connected so that the new transmitter code would be stored in that address. After all of the address storage capacity have been used additional codes would erase all old codes in the memory address storage before storing a new one.
Although the invention has been described with respect to preferred embodiments, it is not to be so limited as changes and modifications may be made which are within the full intended scope as defined by the appended claims.
