[0001] The invention relates in general to movable barrier operators and in particular to
movable barrier operators such as garage door operators or gate operators which include
passive infrared detectors associated with them for detecting the presence of a person
or other high temperature object for controlling a function of the movable barrier
operator such as illumination.
[0002] A wall control unit for a movable barrier is described in GB-A-2 312 540.
[0003] It has been known to use pyroelectric infrared detectors or passive infrared (PIR)
detectors for the detection of a person in a particular vicinity. For instance, it
is well known that pyroelectric infrared detectors can be used in combination with
illumination lamps, carriage lamps, spot lamps and the like to form a low cost home
security system. The pyroelectric infrared detector typically has a plurality of segments.
One or more of the segments may be actuated by infrared radiation focused thereon
by a Fresnel lens positioned in front of the PIR detector. The pyroelectric detector
provides an output signal when a change occurs in the potential level between one
element and another element in the array. Such an infrared detected voltage change
indicates that a warm object radiating infrared radiation, typically a person, is
moving with respect to the detector. The detectors to provide output signals upon
receiving infrared radiation in about the ten micron wavelength range. The micron
infrared radiation is generated by a body having a temperature of about 90° F., around
the temperature of a human body. (98.6° F.).
[0004] It is also known that garage door operators or movable barrier operators can include
a passive infrared detector associated with the head unit of the garage door operator.
The passive infrared detector, however, needed some type of aiming or alignment mechanism
associated with it so that it could be thermally responsive to at least part of the
garage interior. The detectors were connected so that upon receiving infrared energy
from a moving thermal source, they would cause a light associated with the garage
door operator to be illuminated.
[0005] It was known in the past to use timers associated with such systems so that if there
were no further thermal signal, the light would be shut off after a predetermined
period. Such units were expensive as the passive infrared detector had to be built
into the head unit of the garage door operator. Also, the prior PIR detectors were
fragile. During mounting of the head unit to the ceiling of the garage a collision
with the aiming device associated with the passive infrared detector might damage
them. The ability to aim the detection reliably was deficient, sometimes leaving blank
or dead spots in the infrared coverage.
[0006] Still other operators using pivoting head infrared detectors required that the detector
be retrofitted into the middle of the output circuit of a conventional garage door
operator (see US-A-5 589 747). This would have to have been done by garage door operator
service personnel as it would likely involve cutting traces on a printed circuit board
or the like. Unauthorized alteration of the circuit board by a consumer might entail
loss of warranty coverage of the garage door operator or even cause safety problems.
[0007] What is needed then is a passive infrared detector for controlling illumination from
a garage door operator which could be quickly and easily retrofitted to existing garage
door operators with a minimum of trouble and without voiding the warranty.
[0008] It is an object of the present invention to provide a quickly and easily retrofitted
passive infrared detector for controlling the illumination of a garage door operator
through conventional signalling channels.
[0009] It is another object of the instant invention to provide a garage door operator having
a passive infrared detector which passive infrared detector can control a variety
of garage door operators.
[0010] According to a first aspect of the invention, there is provided a wall control unit
for a movable barrier operator for sending baseband signals to a head unit of a movable
barrier operator to command a movable barrier to perform barrier operator functions,
comprising: a wall control unit port for connection to a wired connection to a head
unit of a movable barrier operator; a first switch for sending a barrier command signal
to the head unit commanding the head unit to open or close a movable barrier; a second
switch for commanding the head unit to provide energization to a light source; and
a passive infrared detector for causing a command signal to be sent to the head unit
to control the illumination state of the light source.
[0011] According to a second aspect of the invention, there is provided a movable barrier
operator having an illumination controller, comprising: a head unit of a movable barrier
operator to command the movable barrier to perform barrier operator functions; a wall
control unit according to any preceding claim for sending baseband signals to the
head unit via a communications port; and said passive infrared detector being arranged
for causing a command signal to be sent to the head unit over the wired connection
to control the illumination state of said light source.
[0012] Other aspects and advantages of the present invention will become obvious to one
of ordinary skill in the art upon a perusal of the following specification and claims
in light of the accompanying drawings, in which:

5; and
FIGS. 12A-H are flow charts showing details of a program flow controlling the operation

[0013] The following describes a passive infrared detector for a garage door operator including
a passive infrared detector section connected to a comparator for generating a signal
when a moving thermal or infrared source signal is detected by the passive infrared
detector. The signal is fed to a microcontroller. Both the infrared detector and the
comparator and the microcontroller are contained in a wall control unit. The wall
control unit has a plurality of switches which would normally be used to control the
functioning of the garage door operator and are connected in conventional fashion
thereto.
[0014] The PIR detector is included with the switches for opening the garage door, closing
the garage door and causing a lamp to be illuminated. The microcontroller also is
connected to an illumination detection circuit, which might typically comprise a cadmium
sulphide (CdS) element which is responsive to visible light. The CdS element supplies
an illumination signal to an ambient light comparator which in turn supplies an illunimator
level signal to the microcontroller. The microcontroller also controls a setpoint
signal fed to the comparator. The setpoint signal may be adjusted by the microcontroller
according to the desired trip point for the ambient illumination level.
[0015] The microcontroller also communicates over the lines carrying the normal wall control
switch signals with a microcontroller in a head unit of the garage door operator.
The wall control microcontroller can interrogate the garage door operator head unit
with a request for information. If the garage door operator head unit is a conventional
unit, no reply will come back and the wall control microcontroller will assume that
a conventional garage door operator head is being employed. In the event that a signal
comes back in the form of a data frame which includes a flag that is related to whether
the light has been commanded to turn on, the microcontroller can then respond and
determine in regard to the status of the infrared detector and the ambient light whether
the light should stay on or be turned off.
[0016] In the event that a conventional garage door operator head is used, the microcontroller
can, in effect, create a feedback loop with the head unit by sending a light toggling
signal to the microcontroller in the head unit commanding it to change the light state.
If the light turns on, the increase in illumination is detected by the cadmium sulphide
sensor and so signaled to the microcontroller head allowing the light to stay on.
If, in the alternative, the light is turned off and the drop in light output is detected
by the cadmium sulphide detector, the wall control microcontroller then retoggles
the light, switching it back on to cause the light to stay on for a full time period
allotted to it, usually two-and-one-half to four-and-one-half minutes.
[0017] Referring now to drawings and especially to FIG. 1, a movable barrier operator embodying
the present invention is shown therein and generally identified by reference numeral
10. The movable barrier operator, in this embodiment a garage door operator 10, is
positioned within a garage 12. More specifically, it is mounted to a ceiling 14 of
the garage 12 for operation, in this embodiment, of a multipanel garage door 16. The
multipanel garage door 16 includes a plurality of rollers 18 rotatably confined within
a pair of tracks 20 positioned adjacent to and on opposite sides of an opening 22
for the garage door 16.
[0018] The garage door operator 10 also includes a head unit 24 for providing motion to
the garage door 16 via a rail assembly 26. The rail assembly 26 includes a trolley
28 for releasable connection of the head unit 24 to the garage door 16 via an arm
30. The arm 30 is connected to an upper portion 32 of the garage door 16 for opening
and closing it. The trolley 28 is connected to an endless chain to be driven thereby.
The chain is driven by a sprocket in the head unit 24. The sprocket acts as a power
takeoff for an electric motor located in the head unit 24.
[0019] The head unit 24 includes a radio frequency receiver 50, as may best be seen in FIG.
2, having an antenna 52 associated with it for receiving coded radio frequency transmissions
from one or more radio transmitters 53 which may include portable or keyfob transmitters
or keypad transmitters. The radio receiver 50 is connected via a line 54 to a microcontroller
56 which interprets signals from the radio receiver 50 as code commands to control
other portions of the garage door operator 10.
[0020] A wall control unit 60 embodying the present invention, as will be seen in more detail
hereafter, communicates over a line 62 with the head unit microcontroller 56 to effect
control of a garage door operator motor 70 and a light 72 via relay logic 74 connected
to the microcontroller 56. The entire head unit 24 is powered from a power supply
76. In addition, the garage door operator 10 includes an obstacle detector 78 which
optically or via an infrared pulsed beam detects when the garage door opening 22 is
blocked and signals the microcontroller 56 of the blockage. The microcontroller 56
then causes a reversal or opening of the door 16. In addition, a position indicator
80 indicates to the head unit microcontroller 56, through at least part of the travel
of the door 16, the door position so that the microcontroller 56 can control the close
position and the open position of the door 16 accurately. FIGS. 3A-C are schematic
diagrams of a portion of the electrical system shown in FIG. 2.
[0021] The wall control 60, as may best be seen in FIG. 4, includes a passive infrared sensor
100 having an output line 102 connected to a differential amplifier 104. The differential
amplifier 104 feeds a pair of comparators 106 and 108 coupled to a wall control microcontroller
110, in this embodiment a Microchip PIC 16505. The sensor 100 changing signals from
the comparators when the infrared illumination changes at the passive infrared sensor
100. The microcontroller 110 provides an output at line 112 to the line 62, which
is connected to the microcontroller in the GDO head. Also associated with the wall
control is a momentary contact light switch 120, a door control switch 122, a vacation
switch 124, and an auto-manual select switch 126. The light switch 120 is connected
through a capacitor 130 to other portions of the wall control 60. The vacation switch
124 is connected through a capacitor 132 to the wall control 60. The capacitor 132
has a different value than the capacitor 130. The wall control 60 controls the microcontroller
56 through its switches by the effective pulse width or charging time required when
a respective switch closes as governed by its associated capacitor or by the direct
connection, as is set forth for the door control switch 122.
[0022] In addition, an ambient light sensor 140 is provided connected in a voltage divider
circuit having a variable resistance 134 which feeds a comparator 150 which supplies
an ambient light level signal over a line 152 to the microcontroller 110.
[0023] In addition, the microcontroller 110 supplies a setpoint signal on a line 160 back
to the comparator 150 so that the microcontroller 110, through the use of pulse width
modulation, can control the setpoint of the light level comparator 150 to determine
the point where the ambient light comparator 150 trips and thereby determine the ambient
light illumination level. FIGS. 5-11 are various views of the wall control 60 discussed
above. FIGS. 12A-H are flow charts showing details of a program flow controlling the
apparatus of microcontroller 56 contained within the wall control 60 as shown in FIGS.
3A-C.
[0024] As may best be seen in FIG. 12 when the processor or microcontroller 110 powers up
ports and outputs are set as well as the timer in a step 500 at which point a main
loop is entered and the timer is read in a step 502. A test is made to determine if
10 milliseconds have elapsed in step 504 if they have not, control is transferred
back to step 502. If they have, the pulse width modulation cycle is cleared in a step
506 in order to start the pulse width modulation to govern the setpoint for the illumination.
In step 508, the pulse width modulation output is turned on and the pulse width modulation
counter is cleared. In step 510, the pulse width modulation counter is incremented
and a test is made to determine whether the pulse width modulation counter is equal
to the pulse width modulation value in a step 512. If it is not, control is transferred
to step 510. If it is, control is transferred to a step 514 where the pulse width
modulator has the counter cleared and is turned off and the pulse width modulation
value is output. Followed by a step 516 where the pulse width modulation counter is
incremented and a test is made to determine whether the value of the pulse width modulation
counter is equal to pwm rem in a step 518. If it is not, control is transferred back
to step 516.
[0025] If it is, as may best be seen in FIG. 12B, the pulse width modulation cycle is incremented
in a step 520, and a test is made in step 522 to determine whether it is equal to
six. If it is not, control is transferred back to step 508 to restart the pulse width
modulation. If it is, the pulse width modulator is turned off in step 526 and a read
comparison is made in a step 530. If the read comparator is high, the plunge counter
is decremented in a step 532, and the increment counter is incremented in a step 534.
In a step 536, the value of the incremented counter is tested to determine whether
it is greater than 10. If it is, the counter is cleared and a step 538. If it is not,
control is transferred to a step 540 where the pulse width remainder value is set
equal to pulse width modulation value compliment.
[0026] In the event that the value of the read comparison step 530 yields a low value, a
leap counter is cleared in a step 550 and a decrement counter is incremented in a
step 552. A test is made in a step 554 to determine whether the decrement counter
value is greater than 10. If it is not, control is passed to step 540. If it is, the
decrement counter is cleared in a step 556 and a test is made to determine whether
the pulse width modulation value is zero in a step 560. If it is zero, control is
transferred to step 540. If it is not, the pulse width modulation value is decremented,
the plunge counter is incremented in a step 562. In a step 564, the plunge counter
is tested to determine whether it is greater than 12. If it is, the pulse width modulation
value is tested for whether it is less than 20 in a step 566. If it is not, the pulse
width modulation value is set equal to the pulse width modulation value minus nine
in a step 568 and control is transferred to the step 540.
[0027] Upon exiting the step 540, as may best be seen in FIG. 12C, a test step 570 is entered
to determine whether the light on state has been set by the head unit of the movable
barrier operator. If it is not, a test is made in a step 522 to determine whether
the awake timer is active. If the awake timer is active, control is transferred to
a step 574 causing a 16-bit counter timer to be incremented and to blank any bit counter.
If the timer is not active, control is transferred to determine whether the blank
timer is active in a step 576. If it is, control is transferred to step 574. If it
is not, control is transferred to a test step 578 to determine whether checking is
active. If checking is active, the checking counter is incremented in the step 530
and a test is made to determine whether the value of the checking counter is equal
to one second in a step 582. If it is not, control is transferred to a test step 600,
as shown in FIG. 12D. If it is, a test is made to determine whether the light-on flag
is on or not in a step 602. If it is on, a test is made in a step 604 to determine
whether the present pulse width modulation value is equal to the stored modulation
value. If it is indicated to be lighter, control is transferred to a step 606 to clear
checking. If it is indicated to be dimmer, control is transferred to a step 608 causing
the work light signal to e toggled by the wall control over the lines connected to
the head unit. If the light-on value flag is indicated to be off, a test is made in
a step 610 to determine whether the present pulse width modulation value is equal
to the stored value. If it's indicated to be dimmer, control is transferred to the
step 606. If it's indicated to be lighter, step 612 turns on the work light toggle
to flip the light state and transfers control to step 606.
[0028] Once the light has been toggled, a test is made in step 600, as shown in FIG. 12D,
to determine whether the awake flag has been set. If it has, a test is made in a step
620 to determine whether the work light toggle is active. If it is, the pulse width
value is incremented in a step 622, and a test is made to determine whether the pulse
width count is equal to 20 (which is equivalent to 200 milliseconds) in a step 624.
If it is not, the work light is toggled off in a step 626. In the event that the awake
flag has not been set, a test is made in a step 630 to determine whether the RC time
constant for the power supply has expired. In other words, has the power been kept
high for more than 1.5 minutes as tested for in step 630. If it has not, control is
transferred back to the main loop in FIG. 12A. If it is, the awake value is set and
the timer is cleared in the step 634, and control is transferred back to the main
loop. In the event that the time constant has expired in step 630, the awake flag
is cleared and the counts are set high in the step 636 after which control is transferred
back to the main loop. After the work light has been toggled and the step 626, a step
is made in a step 660, as may best be seen in FIG. 12E to determine if the blank timer
is active. If it is, it is checked. If it is not, a test is made to determine whether
there is indicated to be activity from the passive infrared input indicating a change
in a step 662. If not, a quiet state is entered. If the PIR has been indicated to
be active, a second test is made to determine whether the PIR still indicates that
it is changing to indicate that a false signal has not been received. If it is, a
test is made to determine whether the work light is on within the garage. If the work
light is on, control is transferred back to the main loop. If the work light is indicated
not to be on, a test is made to determine whether the pulse width value is greater
than 128, in other words, whether the garage is indicated to be bright or dim. If
it is indicated to be bright, indicating it's illuminated control is transferred back
to the main loop. If it's indicated to be dim, control is transferred to the test
step 680, as may best be seen in FIG. 12G to determine whether two-and-one-half seconds
had elapsed. If they have not, the blank timer is turned off in the step 682. If they
have, a test is made in the step 684 to determine whether the light-on state has been
set. If it has, a test is made in a step 686 to determine whether six minutes have
passed. If they have, the timer is cleared, the light-on flag is cleared, the blank
flag is set, and an attempt is made to read the light state from the head unit via
serial communication in a step 688. A test is made in a step 690 to determine whether
the serial communication has been successful. If it has, a test is then made in a
step 692 to determine whether the light-on flag has been returned from the head unit
to the wall control. If it has, indicating the light has been set on, the toggle output
is set in a step 694. If it has not, control has been transferred to the main loop.
If serial communication has failed, as tested for in step 690, the toggle output is
set in a step 700, pulse width modulated value is stored in a step 702, and checking
is set in a step 704 prior to transfer back to the main loop.
[0029] In order to respond to the query function, which is used to interpret the word sent
back by the head unit, as may best be seen in FIG. 12H. In a step 750, there is a
delay until a key reading pulse in a step 752 and a timer is reset in a step 754.
A 500 microsecond delay is waited for in a step 756. A series of delays are used to
generate an on-off output code of varying pulse widths followed by a 100 microsecond
delay in a step 758. A test is then made in a step 760 to determine whether the wall
control input pin is low. If it is not, the test is remade. If it is, control is transferred
to a step 762 to set a flag indicating serial communication is successful. A time
value is set is a step 766 and status is read in a step 768. A test is made in step
770 to determine whether the serial is okay and in a test 772 a brake signal is tested
for and sent.
[0030] In order to respond to the query light, as is shown in FIG. 12F, in a step 800 the
query light is called. A test is made in a step 802 to determine whether it was readable
by a serial communication with the head. If it was, a test is made in a step 804 to
determine whether the light was on. If it was, control is transferred back to the
main loop. If it was not, the toggle output is set to indicate that the state was
light-on in step 806 to force the light to be on.
[0031] In the event that the serial communication was not readable, the toggle output state
was set, its light on in step 810, pulse width modulation value restored in the step
812, and the checking flag is set in the step 814. Attached is an Appendix consisting
of pages A-1 to A-12 which comprises a listing of the software executing on the microcontroller
110.
