Definitions
- 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.
- a wall control unit for a movable barrier is described in GB-A-2 312 540.
- pyroelectric infrared detectors or passive infrared (PIR) detectors for the detection of a person in a particular vicinity.
- PIR passive infrared
- 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.).
- 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 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

- step 500 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.
- step 508 the pulse width modulation output is turned on and the pulse width modulation counter is cleared.
- 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.
- step 516 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- step 608 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.
- 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.
- step 630 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.
- 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.
- 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.
- 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.
- 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.
