Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

Referring to fig. 1 and 2, the window covering device used in the control method includes n window coverings 100 and a synchronous controller 200, where n is a natural number not less than 2, and the n window coverings 100 are respectively a window covering 1 and a window covering 2 … ….

The curtain 100 is an electric curtain, such as a roller curtain, and comprises a curtain cloth 101 and a driving mechanism 102 for electrically controlling the curtain cloth 101 to ascend and descend, wherein the curtain cloth 101 is arranged on a window frame 103, and the curtain cloth 101 is opened when ascending, and the curtain cloth 101 is descended when descending. The lengths (run-in lengths, excluding the wound-up portion) of the curtains 101 are L1 and L2 … … Ln, respectively, which are not completely the same, that is, the lengths of the curtains 101 of at least two curtains 100 are different from each other. Thereby making the stroke of opening or closing of each window covering 100 not identical. Alternatively, the window covering 100 may be an open-close curtain.

The drive mechanism 102 may also be mounted on the window frame 103. The above-mentioned device is the prior art, the driving mechanism 102 can use the existing tubular motor, and drive the curtain cloth 101 to move through the transmission mechanism such as the rope winder. In addition, a communication module is arranged in the driving mechanism 102, so that remote control can be realized. The drive mechanism 102 may drive the fabric 101 to run at a constant linear velocity, where the preset constant linear velocity is v, and then the length of the fabric 101 corresponding to any time t of the running is L ═ vt. The synchronous controller 200 has control and communication functions, and CAN perform bidirectional communication with the driving mechanism 102, and the communication modes include but are not limited to CAN, RS485, and the like. The driving mechanism 102 can report the current length of the curtain 101 of the corresponding curtain 100 to the synchronous controller 200, and can also receive the position required by the synchronous controller 200 to operate. When the synchronous controller 200 controls the window covering 100, the position where the window covering 100 is required to operate is determined, and the synchronous value (including, but not limited to, the longest value and the shortest value of the length of the curtain 101 among the plurality of window coverings 100) to be controlled is also determined. The driving mechanism 102 of the window covering 100 determines when to start operation (or increase or decrease the speed of the window covering) according to the received synchronization values (such as the longest value and the shortest value), so that each window covering 100 can achieve the flush effect.

The control method comprises the following steps:

1) during each control, firstly, the synchronous controller 200 inquires the current length L of the curtain cloth 101 of each curtain 100 to be controlled, sequences the current length L to obtain the shortest length Lmin and the longest length Lmax, and then the synchronous controller 200 sends the target lengths Ld, Lmin and Lmax to be operated to the driving mechanism 102 of each curtain 100 to be controlled;

2) after receiving the above Ld, Lmin, and Lmax, the driving mechanism 102 of each curtain 100 calculates according to the length Lx of the curtain 101 itself to determine a delay start synchronization strategy:

2.1) if Ld > Lx, it means that the corresponding curtain 100 needs to go down, and at this time, the driving mechanism 102 of the curtain 100 will be started with a delay (Lx-Lmin)/v, that is, the uppermost curtain 100 (the curtain with the length of Lmin) is started when running to the position flush with itself, thereby achieving the flush effect;

2.2) if Ld < Lx, it means that the corresponding curtain 100 needs to go upward, and at this time, the driving mechanism 102 of the curtain 100 will be started with a delay (Lmax-Lx)/v, that is, the lowermost curtain 100 (curtain with length Lmax) is started when running to the position flush with itself, thereby achieving the flush effect;

2.3) if Ld ═ Lx, the corresponding shade 100 waits in place without being activated.

The above process is a delayed starting strategy, and the overall effect is that the plurality of curtains 100 are started in sequence and finally run synchronously and horizontally.

Acceleration and deceleration strategies may also be implemented, such as sending Ld, Lmax '(including but not limited to the second longest), Lmin' (including but not limited to the second shortest). Therefore, (Lx-Lmin ')/v or (Lmax' -Lx)/v has a negative value possibly, namely, the motor needs to be started in advance, and the motor can be accelerated at the moment, catch up with other curtain motors and then run at a normal speed, so that the flushing effect is achieved.

Specifically, the method comprises the following steps:

1) in each control, firstly, the synchronous controller 200 queries the current length L of the curtain cloth 101 of each curtain 100 to be controlled, and performs sequencing to obtain Lmin 'and Lmax', wherein Lmin 'is a value greater than the minimum length in each current length, such as the second shortest value, and Lmax' is a value less than the longest length in each current length, such as the second longest value; then the synchronous controller 200 sends the target lengths Ld, Lmin 'and Lmax' required to be operated to the driving mechanism 102 of each curtain 100 required to be controlled;

2) after receiving the above-mentioned Ld, Lmin 'and Lmax', the driving mechanism 102 of each curtain 100 calculates the length Lx of the curtain 101 itself to determine a synchronization strategy:

2.1) if Ld > Lx, it means that the corresponding curtain 100 needs to go down, and at this time, the driving mechanism 102 of the curtain 100 will delay t to (Lx-Lmin')/v to start, and if t >0, it is delay start; if t is less than 0, accelerating pursuit is needed; if t is equal to 0, starting immediately, and achieving the flush effect;

2.2) if Ld < Lx, it means that the corresponding curtain 100 needs to go upward, and at this time, the driving mechanism 102 of the curtain 100 is started with a delay of t ═ (Lmax' -Lx)/v, and if t >0, it is started with a delay; if t is less than 0, accelerating pursuit is needed; if t is equal to 0, starting immediately, and achieving the flush effect;

Similarly, the motor needing delayed starting can be started immediately and run at a low speed, and the motor can run at a normal speed after other motors arrive, so that the leveling effect is achieved.
