The method comprises pressing at least one button to initiate setting low touch sensitivity value; detecting a first manual movement of the drape; determining a first number of ticks using an encoder associated with the first manual movement; determining a low end user sensitivity signature value by calculating the average first number of ticks of the encoder; pressing at least one another button to initiate setting high touch sensitivity value; detecting a second manual movement of the drape; determining a second number of ticks using the encoder associated with the second manual movement; and determining a high end user sensitivity signature value by calculating the average first number of ticks of the encoder over the first time period.

Description

BACKGROUND OF THE INVENTION

Technical Field

Aspects of the embodiments relate generally to drapery track systems, and more specifically to system and method for controlling a motorized drapery track assembly.

Background Art

Drapery track systems for use to cover openings or fixtures in residential and commercial settings have made significant improvements in recent years. A drapery track system typically consists of a track, track carriers, drape attached to the track carriers, and a mechanism for moving the drape back and forth along the track. The track is mounted either to a wall or ceiling and the mechanism for moving the drape can be as simple as a pull cord-pulley system.
More sophisticated drapery track systems use a motor to move the drape along the track. Motorized drapery track systems can be automated to automatically open and close. Unlike a manually controlled drapery system, where the user walks up to the window and opens or closes the drape using a cord, a wand, or by pulling on the drape, motorized drapery systems make it easy to open or close one or multiple drape with the touch of a button, or by programming them to automatically move at a specific time with no direct user interaction.
However, typical motorized drapery systems use a standard user interface for setting up motion parameters and options to operate the system. Some of these features have customizable values with a very limited range options. Particularly for motorized drapery systems, when setting up motion parameters such as the force or touch sensitivity to trigger an open and close of drape, these parameters are typically set in an ad hoc or fuzzy value that might not be easily quantized or intuitively matched by all users in the same way. For example, what might be a very light tug for a strong individual user might end up being a medium intensity pull for another user. Further, there are times when a user may want to quickly manually move just a little fabric, and this might trigger the unintentional motorized action.
Accordingly, a need has arisen for system and method for setting touch sensitivity signature values for drape to open and close that are unique to a user.

MODE(S) FOR CARRYING OUT THE INVENTION

Aspects of the embodiments relate generally to drapery track systems, and more specifically to setup touch sensitivity signature values. While the different aspects of the embodiments described herein pertain to the context of drapery track systems, they are not limited thereto, except as may be set forth expressly in the appended claims. For example, the methods described herein can be used on any type of motorized track systems, such as motorized doors, panels, gates, or the like. The embodiments described herein may be further adapted in other types of motorized window or door treatments, such as motorized roller shades, inverted rollers, Roman shades, Austrian shades, pleated shades, blinds, shutters, skylight shades, garage doors, or the like.
Referring to FIG. 1, there is shown an illustrative diagram of a drapery track assembly 100 for use in either a residential or commercial settings. Drapery track assembly 100 may be mounted to a wall or a ceiling using hardware (not shown) above a window or opening 101. The drapery assembly 100 may include a track 102, a motor assembly 103, a master carrier 104 and auxiliary carriers 105. The drapery track assembly 100 may further comprise one or more drape 108 comprising fabric or other covering material. Drape assemblies typically fall into one of two categories: single drape assemblies or double drape assemblies. For example, the drapery track assembly 100 may comprise a single drape assembly, as shown in FIG. 1, including a single drape 108. In another embodiment, the drapery track assembly 100 may comprise a double drape assembly that includes two drapes, each covering a portion of an opening. Each drape in a double drape assembly is attached to a master carrier that closes toward and opens away from the center of the opening. The two master carriers may be synchronized to move in unison (i.e., both are opening or both are closing). While the present embodiments are described with reference to a single drape assembly, the techniques described herein may apply to either the single drape assembly, the double drape assembly, or any number of drape assemblies.
Track 102 may comprise a longitudinal body made up of one, two, or several track pieces joined together. Track 102 may comprise a channel disposed therein configured to retain carriers 104 and 105. Carriers 104 and 105 may be held in movable linear mechanical restraint within the channel of track 102 and may comprise wheels (not shown) allowing carriers 104 and 105 to linearly travel within the channel of track 102. Carriers 104 and 105 may comprise drapery supporting elements 109, such as hooks or loops, designed to retain pre-strengthened points or holes along the top edge 115 of the drape 108. Particularly, the master carrier 104 is attached to the leading top edge 114 of the drape 108 and the auxiliary carriers 105 are attached along the remainder top edge 115 of the drape 108 at substantially equal intervals. As a result, the drape 108 comprises vertical pleats 113 between the carriers 104 and 105.
The motor assembly 103 may comprise a controller 110 and a motor 201 (FIGS. 2 and 3) for driving the master carrier 104 along track 102. According to an embodiment, the motor 201 may be configured to spin an output shaft 304 (FIG. 3) in either a clockwise or a counterclockwise direction, depending on the desired direction of travel. The output shaft 304 may be connected to a gearing assembly configured to drive a drive belt or a timing belt. The master carrier 104 may be driven by the belt such that rotating the motor 201 in one direction causes the master carrier 104 to linearly move along the length of the track 102 in direction 116 and pull the leading edge 114 of the drape 108 as well as the auxiliary carriers 105 to extend the drape 108 to a closed position. Similarly, rotating the motor 201 in an opposite direction causes the master carrier 104 to linearly move along the length of the track 102 in direction 117 and push the leading edge 114 of the drape 108 as well as the auxiliary carriers 105 to retract the drape 108 to an opened position. In one embodiment, the drapery track assembly 100 may comprise similar configuration to the drapery track system shown and disclosed in U.S. patent application Ser. No. 14/479,631, filed Sep. 8, 2014, and titled “Drapery Track System”, the entire contents of which are hereby incorporated by reference. In another embodiment, instead of a timing belt, the drapery track assembly 100 may utilize a pulley system, or the like.
To extend and retract the drape 108 to a desired position, the master carrier 104 linearly travels along the length of the track 102 according to a control command signal received by the controller 110. According to an embodiment, the controller 110 may receive control commands from an external control point 112, such as a user interface in a form of a keypad. The user interface 112 may be wired to the controller 110 or may transmit control commands wirelessly to the controller 110. In a further embodiment, the control command may also comprise information pertaining to the desired speed of the master carriers 104. The speed of the master carriers 104 may be varied to account for circumstances or application. In some instances, a smooth non-disruptive motion of the drape 108 is preferred. In other instances, the drape 108 may need to be closed suddenly. This is particularly useful in certain applications such as in a theater where large drapes are opened and closed at various times and speeds for dramatic effect.
FIG. 2 is an illustrative block diagram of a motor assembly 103. The motor assembly includes a controller 110 for use in the drapery track assembly 100 and a motor 201 according to one embodiment. The controller 110 is connected to the motor 201, which is configured to drive the master carrier 104. According to an embodiment, the motor 201 may be a brushless direct current (DC) motor.
In an embodiment, the controller 110 may comprise of a central processing unit (CPU) 202. The controller 110 for setting up or establishing sensitivity signature values may be based on the CPU 202. CPU 202 can represent one or more microprocessors, and the microprocessors can be “general purpose” microprocessors, a combination of general and special purpose microprocessors, or application specific integrated circuits (ASICs). Additionally, or alternatively, the CPU 202 can include one or more reduced instruction set (RISC) processors, video processors, or related chip sets. The CPU 202 can provide processing capability to execute an operating system, run various applications, and/or provide processing for one or more of the techniques and functions described herein. For example, the CPU 202 can process various commands and perform operations, such as controlling the direction, position, and speed of the motor 201 in response to receiving desired position commands from the external control point 112.
According to an embodiment, the CPU 202 may comprise two microcontrollers. A first microcontroller may be designated as the master microcontroller that handles network traffic, external user interface, application logic, and will keep high level view of the motion state. A second microcontroller may be a slave microcontroller that communicates with the master microcontroller and handles controlling the motor 201 with Hall Effect sensors feedback, as will be described below. This second microcontroller may keep a low level motion state and perform dedicated tasks, such as motor position tracking, motor communication control, current intensity feedback, overcurrent monitoring by constantly reading the hall effect sensor in real time, or the like. However, a single or any number of microcontrollers may be utilized.
The controller 110 can further include a memory 203 communicably coupled to the CPU 202. The memory 203 may store information accessible by CPU 202, including instructions for execution by the processor 202. The memory 203 can represent nonvolatile memory, such as read-only memory (ROM) or Flash memory, or can also include volatile memory such as random-access memory (RAM). In buffering or caching data related to operations of the CPU 202, memory 203 can store data associated with applications running on the control processor 202.
The controller 110 may comprise a power supply 206 configured for providing power to the various components of the controller 110. The power supply 206 may be connected to a voltage line for receiving an electric alternating current (AC) power signal from an AC mains power source. The power supply 206 may comprise circuit components configured for converting the incoming AC power signal to a direct current (DC) power signal. In another embodiment, the controller 110 may be connected to an external power supply for receiving a DC power signal.
In an embodiment, the controller 110 may comprise a user interface 207, such one or more buttons, configured for enabling configuration of the drapery track assembly 100 as well as receiving position control commands directly from a user. The user interface 207 may further comprise one or more light indicators, such as light emitting diodes (LED) 210, to provide feedback to the user as to the status of saving the low and high end user sensitivity signature values. When one of the sensitivity signature values is stored in the memory 203, at least one of the LEDs may blink, for example three times, to indicate that one of the sensitivity signatures was stored successfully. The LED 210 may turn on and off according to a predetermined pattern, timing, color and function to achieve predetermined lighting effects.
In another embodiment, the controller 110 further comprises an interface 205, such as a wired or a wireless interface, configured for receiving control commands from an external control point 112. The wireless interface may be configured for bidirectional wireless communication with other electronic devices, such as the external control point 112, over a wireless network. The wireless network interface may comprise a radio frequency (RF) transceiver configured for bidirectional wireless communication using wireless communication protocols, such as the ZigBee® protocol, the infiNET EX® protocol from Crestron Electronics, Inc. of Rockleigh, N.J., or the like. In another embodiment, the wireless interface may in addition or alternately comprise an infrared (IR) interface.
The control commands received by the controller 110 may be a direct user input to the controller 110 from the user interface 207 or a wired or wireless signal from an external control point 112. For example, the controller 110 may receive a control command from a wall-mounted button panel or a touch-panel in response to a button actuation or similar action by the user. Control commands may also originate from a signal generator such as a timer or a sensor. In an embodiment, a timer may be configured for transmitting a control input to the controller 110 at a predetermined time. The timer may be set according to personal preferences or for security reasons. In another embodiment, a light sensor may be configured for transmitting a control input to the controller 110 in response to sensing a predetermined level of sunlight.
In various aspects of the embodiments, the interface 205 and/or power supply 206 can comprise a Power over Ethernet (PoE) interface. The controller 110 can receive both the electric power signal and the control input from a network through the PoE interface. For example, the PoE interface may be connected through category 5 cable (CAT5) to a local area network (LAN) which contains both a power supply and multiple control points and signal generators. Additionally, through the PoE interface, the controller 110 may interface with the internet and receive control inputs remotely, such as from a homeowner running an application on a smart phone.
The controller 110 may further comprise one or more Hall effect sensors 204 connected to the motor 201 and configured for determining the direction, speed, detection of a pull or tug on the drape, and position of the motor's shaft. The sensors 204 detect manual movement of the drape 108 for a certain time period. Each Hall effect sensor 204 may comprise a transducer that varies its output voltage in response to a magnetic field. The CPU 202 may employ the information provided by the Hall effect sensors 204 as a feedback for control of the motor 201.
The controller 110 further comprises a current sensing circuit 208 configured for sensing the current drawn by the motor 201. According to an embodiment, the current sensing circuit 208 may comprise a current sense resistor and an amplifier along with a low pass filter. However, other type of current sensing components may be utilized. For example, the current sensing circuit 208 may comprise a Hall effect sensor for measuring current levels. The CPU 202 may employ the information provided by current sensing circuit 208 as a feedback for control of the motor 201.
The controller 110 further comprises at least one button 209. In one embodiment, there are three buttons 209. The buttons are used by the user to setup the touch sensitivity signature values. Button 209 could be a tactile switch or any momentary switch.
A user establishes touch sensitivity signature values by pulling or tugging the drape 108. By physically pulling or tugging the drape 108, the user instructs the draper track assembly 100 what force, touch, tug or pull signature values to use as minimum and maximum thresholds to initiate an open or close of the drape 108. The touch sensitivity signature values for opening and closing the drape 108 are therefore unique to that individual user. Further, the user has a bigger spectrum of setting touch sensitivity values. In one embodiment, the user is able to setup a pair of low end and high end touch sensitivity signature values for each opening and closing of the drape 108. The low end touch sensitivity value is the minimum touch sensitivity signature value to initiate the opening or closing of the drape 108 depending on the direction of the manual tug or pull (e.g., closing direction 116 and opening direction 117) by the user. The high end touch sensitivity value is the maximum touch sensitivity signature value to open or close the drape 108 depending on the direction of the manual tug or pull (e.g., closing direction 116 and opening direction 117) by the user. Both the low and high end touch sensitivity signature values for opening and closing of the drape 108 are stored in the memory 203. For example, in operation, the drape 108 would only move to a close or open position if the user's tug results in a sensitivity value that is higher than the low end touch sensitivity signature value and less than the high end touch sensitivity signature value. Otherwise, the drape 108 would not move and remain in the same position.
Setup for Opening the Drape:
To initiate the touch sensitivity learning mode for low end touch sensitivity signature value, beginning with the drape 108 being in a fully closed position, a user may press at least one button 209. In one embodiment, the user may press a first button for setup mode and a second button simultaneously for opening the drape 108. The one or more Hall effect sensors 204 is configured to detect a manual movement by the user pulling or tugging on the drape 108 towards the open direction 117 for a period of time. The user may tug the drape 108 for five (5) milliseconds to two (2) seconds.
Continuing on to establishing touch sensitivity and referring to FIG. 3, the motor assembly 103 further includes an encoder 300, printed circuit board (PCB) for the encoder 302 and an output shaft 304. The output shaft 304 is attached to the end of the motor 201. The encoder 300 is configured to determine a number of ticks associated with the user pulling or tugging on the drape 108 during a time period. In one embodiment, the encoder 302 may be a quadrature encoder, however it should be understood that other types of encoder may also be used, such as optical encoders, mechanical encoders, etc. The quadrature encoder uses two output channels to sense position. Using two code tracks with sectors positioned 90 degrees out of phase, the two output channels of the quadrature encoder indicate both position and direction of rotation. By monitoring the number of pulses and the relative phase of signals (i.e., two output channels), the position and direction of rotation can be tracked. The controller 110 advantageously counts these pulses to determine the operational and positional characteristics of the drape 108. The number of pulses output by the encoder 302 may be associated with a linear displacement of the drape 108 by a distance/pulse conversion factor or a pulse/distance conversion factor. The controller 110 is configured to determine a low end user sensitivity signature value by calculating the average number of ticks of the encoder 302 over the time period.
The low end user sensitivity value is stored in the memory 203. When one of the sensitivity signatures is stored in the memory 203, at least one of the LEDs 210 may blink, for example three times so that the user knows that the low end user sensitivity value was calculated and stored successfully in the memory 203. In another embodiment, the LEDs 210 may turn on and off according to a predetermined pattern, timing, color and function to achieve predetermined lighting effects. The lighting effects may include patterns, a time display, and a color changing display.
To initiate the touch sensitivity learning mode for high end user touch sensitivity signature value, again beginning with the drape 108 being in a fully closed position, a user may press at least one button 209. In one embodiment, the user may press a first button for setup mode and another second button simultaneously for opening the drape 108. The steps for setting the high end user touch sensitivity value is similar to the low end user touch sensitivity value. The one or more Hall effect sensors 204 is configured to detect a manual movement by the user pulling or tugging on the drape 108 in the open direction 117 for a period of time. The manual movement for setting the high end user touch sensitivity signature value has a higher tug or pull than setting up the low end user touch sensitivity signature value.
The encoder 302 is configured to determine a number of ticks associated with the manual movement during the time period. The controller 110 is configured to determine a high end user sensitivity signature value by calculating the average number of ticks of the encoder 302 over the first time period. The higher the number of ticks for a given time period corresponds to a higher force being applied on the drape 108 being pulled or tugged by the user and consequently the faster the drape 108 is being pulled or tugged. Conversely, the lower the number of ticks corresponds to the lower the force being applied on the drape 108 and consequently the slower the drape 108 is being pulled or tugged. The high end user sensitivity signature value is stored in the memory 203. The LEDs 210 may provide feedback to the user that the high end user sensitivity signature value was stored in the memory 203 by blinking a number of times.
Setup for Closing the Drape:
In another embodiment, the user may continue to establish low and high end signature sensitivity values for closing the drape 108. To initiate the touch sensitivity learning mode for low and high end touch sensitivity signature values, beginning with the drape 108 being in a fully opened position, a user may press at least one button 209. The user may then continue to establish these sensitivity values in a manner that are similar to establishing the low and high end sensitivity values for opening the drape but the user is pulling or tugging towards the closing direction 116.
In Operation:
Now that the low and high end user sensitivity signature values are calculated and stored, the user may want to close the drape. The user manually tugs or pulls the drape 108 for a time period, which could be five (5) milliseconds, in the closing direction 116. The encoder 300 determines a number of ticks associated with the manual movement or operational movement for the timer period. The controller 110 determines an operational sensitivity value by calculating the average number of ticks of the encoder over the time period. If the operational sensitivity value is greater than the low end user sensitivity signature value and less than the high end user sensitivity value, the motor moves the drape 108 towards the closing direction 116 until the drape 108 is in a substantially closed position. Otherwise, the motor would not move the drape 108 but rather stay stationary or at the same current position.
If the user wants to open the drape 108, the user would tug or pull on the draped in the opening direction 117 for a time period, which could be five (5) milliseconds. The encoder 300 determines a number of ticks associated with the manual movement or operational movement for the timer period. The controller 110 determines an operational sensitivity value by calculating the average number of ticks of the encoder over the time period. If the operational sensitivity value is greater than the low end user sensitivity signature value and less than the high end user sensitivity value, the motor moves the drape 108 towards the opening direction 117 until the drape 108 is in a substantially opened position. Otherwise, the motor would not move the drape 108 but rather stay stationary or at the same current position.
FIG. 4 is a flow chart 400 illustrating an embodiment of the present disclosure. The functionality illustrated therein is implemented, generally, as instructions executed by the CPU 202. Flow chart 400 illustrates a method for controlling a motorized drape. The user establishes touch sensitivity signature values for low and high end for closing and opening the drape 108. Initially, the user establishes low and high end user sensitivity signature values to open the drape 108. As such the drape is initially in a fully closed position. In step 405, the user presses at least one button 209 to initiate setting low touch sensitivity signature value. In step 410, one or more Hall effect sensors 204 detects a manual movement by the user pulling or tugging on the drape 108 towards the open direction 117 (e.g., first manual movement) for a first time period. The user may tug the drape 108 for five (5) milliseconds to two (2) seconds. An encoder 300 determines a first number of ticks associated with the first manual movement during the first time period in step 415. In step 420, a controller 110 determines the low end user sensitivity signature value by calculating the average first number of ticks over the first time period. In step 425, the controller 110 then stores the low end user sensitivity signature value in a memory 203.
The next step is to establish the high end user touch sensitivity signature value. To this end, in step 430, the user presses at least one another button 209. In step 435, one or more Hall effect sensors 204 detects a second manual movement of the drape 108 during the first time period. In step 440, the encoder 300 determines a second number of ticks associated with the second manual movement during the time period. In step 445, a controller 110 determines a high end user sensitivity signature value by calculating the average first number of ticks of the encoder over the first time period. The high end user sensitivity signature value is stored in the memory 203 in step 450.
FIG. 5 is a flowchart 500 that illustrates another method for controlling a motorized drape. The user establishes touch sensitivity signature values for low and high end for closing and opening the drape 108. Initially, the user establishes low and high end user sensitivity signature values to open the drape 108. As such the drape 108 are initially in a fully closed position. In step 505, the user presses at least one button 209 to initiate setting low touch sensitivity signature value. In step 510, one or more Hall effect sensors 204 detects a manual movement by the user pulling or tugging on the drape 108 towards the open direction 117 (e.g., first manual movement) for a first time period. The user may tug the drape 108 for five (5) milliseconds to two (2) seconds. An encoder 300 determines a first number of ticks associated with the first manual movement during the first time period in step 515. In step 520, a controller 110 determines the low end user sensitivity signature value by calculating the average first number of ticks over the first time period. In step 525, the controller 110 then stores the low end user sensitivity signature value in a memory 203. The user interface 207 turns on and off at least one LED 210 in response to the low end user sensitivity signature being stored in the memory 203 in step 530. As such, the LED 210 provides feedback to the user that the low end user sensitivity signature value is stored properly in the memory 203.
The next step is to establish the high end user touch sensitivity signature value. To this end, in step 535, the user presses at least one another button 209. In step 540, one or more Hall effect sensors 204 detects a second manual movement of the drape 108 during the first time period. In step 545, the encoder 300 determines a second number of ticks associated with the second manual movement during the time period. In step 550, a controller 110 determines a high end user sensitivity signature value by calculating the average first number of ticks of the encoder over the first time period. The high end user sensitivity signature value is stored in the memory 203 in step 555. The user interface 207 turns on and off at least one LED 210 in response to the high end user sensitivity signature being stored in the memory 203 in step 560.
In operation, when the user wants to open the drape 108, the user would pull or tug the drape 108 in the opening direction 117. The Hall effect sensors 204 detect the operational manual movement of the drape 108 for a second time period in step 565. The second time period may be the duration of the user pulling or tugging on the drape 108. The encoder 300 determines a third number of ticks using the encoder associated with the operational manual movement during the second time period in step 570. The controller 110 creates an operational sensitivity value by calculating the average third number of ticks of the encoder 300 over the second time period in step 575. The controller 110 determines if the operational sensitivity value is greater than the low end user sensitivity signature value and less than the high end user sensitivity value in step 580. If the operational sensitivity value is greater than the low end user sensitivity signature value and less than the high end user sensitivity value, the controller 110 moves the drape 108 to a different position using a motor 201 in step 585. However, if the operational sensitivity value is less than the low end user sensitivity signature value or greater than the high end user sensitivity value, the controller 110 keeps the drape 108 in a current position in step 590.
