Description

Control method for preventing misoperation of electric curtain

Technical Field

The invention relates to the technical field of automatic control, in particular to a control method for preventing misoperation of an electric curtain.

Background

Along with the development and popularization of artificial intelligence and internet of things, various devices realize intelligent control, for example, a mobile phone APP one-key controls the running states of various household appliances, and a curtain is used as an essential infrastructure of daily families, and the control mode is more and more diversified. The internet of things technology is combined with the traditional control technology, so that the control modes of the household appliances become diversified, the curtain control is changed from the traditional hand-pulling mode into the mode combining hand pulling and remote control, and a user can flexibly control the curtain according to own requirements.

With the development of curtain control technology, more and more problems are generated, and when two curtain tracks are only very close to each other based on the actual situation, one curtain can be driven to move together when being started, so that an abnormal situation occurs. A rolling shutter rail, a curtain rail, as disclosed in chinese patent application No. 201620745245.1, comprising: the rail main body is internally provided with a rectangular first rail cavity; the track comprises a first side plate and a second side plate, wherein the first side plate and the second side plate are arranged on two sides of a track main body respectively, a first buckle and a second buckle are arranged on the first side plate at intervals, a third buckle and a fourth buckle are arranged on the second side plate at intervals, a second track cavity is formed between the first side plate and the second side plate by the first buckle, the third buckle and the track main body, and a third track cavity is formed between the first side plate and the second side plate by the first buckle, the second buckle, the third buckle and the fourth buckle. Through the structure, the curtain can move freely, the flexibility of the curtain is improved, but the situation that braking traction occurs when the two tracks have to be close to each other according to actual conditions is not considered.

Still like the (window) curtain system that chinese patent application No. 201620743330.4 disclosed, including (window) curtain track, fixed subassembly and casement, fixed subassembly is portable to be set up on the (window) curtain track, and the casement sets up on fixed subassembly, and the (window) curtain track includes the track main part, and the track main part is the rectangle form, and the inside of track main part is equipped with the opening track cavity that is the rectangle form, and fixed subassembly is portable to be set up in opening track cavity. Also absent is an emergency mode in the event of an exception.

The technical scheme adopted by the invention for solving the technical problems is as follows: a control method for preventing misoperation of a motorized window curtain comprises a controller and at least two window curtain systems, wherein each window curtain system has a remote control mode and a manual control mode, and the window curtain systems are arranged close to each other in parallel, and the control method is characterized in that: the control method comprises the following steps:

1) the controller controls one of the curtain systems to be started, and the curtain system starts to be opened or closed to become a moving curtain system;

2) the controller sends a control signal to another stationary shade system to cause the manual function of the stationary shade system to lock for a period of time to render the stationary shade system in a non-movable state.

Preferably, in step 2), the locking time is based on the movement time of the moving curtain system, and when the moving curtain system stops moving, the locking is released, and all the curtain systems are in a normal static state.

Further, to facilitate transmission of the control signal to the window covering system, the controller includes a communication module in communication with the window covering system for communication control of the window covering system.

Preferably, the communication module is a PLC.

Preferably, each curtain system comprises a curtain and a rail, the curtain being mounted on the rail, the rails extending in the same direction, the curtains of two adjacent curtain systems being in contact with each other.

Preferably, the curtain system is an opening and closing curtain.

Preferably, each curtain system comprises a curtain and a driving mechanism for driving the curtain to open and close, and the controller controls the corresponding curtain system by sending a control signal to the driving mechanism.

Compared with the prior art, the invention has the advantages that: a communication control mode is added in the controller, when one curtain is in the running process, the other curtain is controlled through communication to enable the manual function of the other curtain to be locked for a period of time, namely the other curtain cannot move, the problem of brake traction prevention in a specific application scene is solved, the curtains can control and move according to an expected scene, friction among the curtains is reduced to a certain extent, the service life is prolonged, and meanwhile, the installation space is saved.

Detailed Description

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

Referring to fig. 1 and 2, the motorized window treatment includes a controller 200 and at least two window treatment systems 100, in this embodiment, two window treatment systems 100.

Each curtain system 100 includes a curtain 101, a driving mechanism 102 for driving the curtain 101 to open and close, and a rail 103, and the curtain 101 is mounted on the rail 103 to be capable of opening and closing with respect to the rail 103. In this embodiment, the window covering system 100 is an open/close curtain. The curtain 101 may be of any suitable size. The driving mechanism 102 is a conventional driving mechanism, such as a tubular motor, and can realize both remote control and manual control modes. The curtain systems 100 are arranged in parallel, and the "parallel arrangement" means that the rails 103 of the curtain systems 100 are arranged in parallel, and the rails 103 extend in the same direction, so that the opening and closing curtains open or close in the same direction.

Alternatively, the window covering system 100 may be a roller shade.

When the rails 103 of two window covering systems 100 are installed too close together due to insufficient space or customer-specific requirements, the blinds 101 of two adjacent window covering systems 100 contact each other (close together). In this particular application scenario, when the controller 200 controls one of the curtain systems 100 to operate normally, since the two curtain systems 100 are close to each other, a problem of traction braking occurs, that is, the curtain 101 of one curtain system 100 moves, and due to friction, the curtain 101 of the other curtain system 100 also moves together. This not only worsens the control of the curtain, but also greatly shortens the service life due to the friction between them.

For this purpose, the controller 200 is provided with a communication module 201, and the communication module 201 can communicate with the driving mechanism 102 and transmit a control signal to control the driving mechanism. Preferably, the communication module 201 is a PLC, and may transmit control information to the driving mechanism 102, or may exchange information with each other to realize bidirectional communication. That is, the controller 200 adds a communication control function to control the window covering system 100.

The control method comprises the following steps:

1) the controller 200 controls the driving mechanism 102 of one of the curtain systems 100 to be activated, and the curtain system 100 starts to be opened or closed to become the moving curtain system 100;

2) the controller 200 sends a control signal to the driving mechanism 102 of another stationary window covering system 100 to lock the manual function of the stationary window covering system 100 for a period of time, such that the curtain 101 of the stationary window covering system 100 is in a non-movable state, the locking time is based on the movement time of the moving window covering system 100, when the moving window covering system 100 stops moving, the locking is released, and all the window covering systems 100 are in a normal stationary state.
