The steps are: first select a time reference, and use the current position of the curtain as the count value of the historical position of the curtain. When the curtain controller is initialized, the count value is set as 0 position count value, that is, the fully closed position of the curtain, convert the curtain position set by the user into a count value with the same time base, and judge the next running direction of the curtain according to the historical position count value and expected position count value of the curtain , and calculate the next action time of the curtain motor, control the execution of the curtain motor according to the running direction of the curtain, control the change of the count value of the historical position according to the clock of the curtain controller, and control the count value of the historical position according to the clock of the curtain controller and the running direction of the curtain , the user has a new location setting before the user reaches the desired location, then repeat the above steps.

Description

A control method of a curtain controller

Field

The invention relates to a control method of a curtain controller, in particular to a curtain controller in home automation, and belongs to the technical field of automatic control.

Background technique

With the continuous improvement of people's demand for quality of life, electric curtains have gradually entered the family. Commonly used electric curtains in the family include electric blinds, electric opening and closing windows, and electric roller shutters. At present, the control of electric curtains is mostly manually activated. And the method of manually stopping when running to the desired position, if people want to stop the curtain at other positions except fully open and fully closed, they must wait and observe with the naked eye after the curtain is started, and press the button when the curtain runs to the desired position The stop button stops the curtain from running, and this mode of operation brings a lot of inconvenience to the user.

In the CN200810241661 patent document, a driving device and method for adjusting the running direction of a roller blind motor is applied for. The control device of the invention includes a motor and a control part of the motor. The control part of the motor includes a microprocessor, a switch circuit, a memory and The control signal circuit is provided with an up key, a down key, and a stop key. The control signal circuit also includes a control signal receiving circuit, a control signal output circuit corresponding to the control signal receiving circuit, a control signal output circuit, and a control signal receiving circuit. Correspondingly, there are code matching keys on the top, and the control method is that the control signal output circuit outputs data information including the control signal output circuit ID code, key position, and function code that can adjust the motor running direction to the control signal receiving circuit, and then controls the curtain motor. To operate, the method proposed in this patent needs to be realized in combination with corresponding control devices. In the CN200810115747 patent document, a blind and its control method are applied. The blind includes mechanisms such as storage blades, a rotating device, a retractable device, a driving device, and a transmission device. It is an invention of a blinds control device and a method thereof, which is realized by reversing and cooperating. In the CN200710079865 patent document, a control method and a control device for an electric roller blind are applied for. The control device of the invention includes a motor and a switch control circuit. The control method adopted is: by storing the upper terminal position, the lower terminal Position and at least one set intermediate position data, use the real-time lifting position data of the sensor, and the controller controls the motor on and off to achieve the control of the blinds. The intermediate position data set by the invention is closely connected with the installation position of the sensor. One intermediate position data just needs to install a plurality of sensors on corresponding position, and the parking position of curtain can only be these intermediate positions, upper end position and lower end position, because sensor is installed between upper end position and lower end position, sensor The installation needs to provide additional power lines and signal lines to connect to the control circuit, which is difficult to realize in practical applications. The method of this invention to control the motor stop is: the lifting position data collected by the sensor in real time and the set intermediate position corresponding to the sensor installation position The data (stored in the microcontroller) are compared, and if the two are the same, the blinds will stop at the selected position.

Contents of the invention

The object of the present invention is to provide a control method of a curtain controller, which not only avoids frequent manual operations by means of sensor feedback curtain controller, but also avoids the need for the user to wait for the curtain to reach the designated position, and the control method is more humane. Moreover, there is no need to install additional sensors to feed back the position of the curtains, which can be implemented through software, avoiding the use of complicated curtain auxiliary devices, and reducing costs.

For achieving the above object, technical scheme of the present invention is:

(1) Select a time base, and convert the full action time of the curtain into an action count value based on the time base, which is called the full action count value of the curtain. Take the fully closed curtain position as the 0 position count value of the curtain, and take the fully opened curtain maximum position count value as the fully open curtain position count value.

(2) The current position of the curtain is used as the count value of the historical position of the curtain. When the curtain controller is initialized, the count value is set to the count value of 0 position, that is, the fully closed position of the curtain.

(3) The curtain position set by the user is converted into a count value with the same time base, which is called the expected position count value of the curtain. When the curtain controller is initialized, the count value is set as the maximum position count value of the curtain, that is, the curtain full open position.

(4) According to the historical position count value and the expected position count value of the curtain, determine the direction of the next step of the curtain running, as shown in Figure 1, the running direction is upward, and in Figure 2, the running direction is right, and calculate the next step of the curtain motor Action time, which is also a count value in units of the selected time base.

(5) According to the running direction of the curtain, the curtain motor is controlled to execute. In Fig. 1, the relay that controls the execution rises is pulled in, and in Fig. 2, the relay that controls the execution is closed; 1 is continuously increasing the historical position count value, and Fig. 2 is continuously decreasing the historical position count value.

(6) According to the clock of the curtain controller and the running direction of the curtain, the count value of the historical position is controlled. If the count value of the historical position is equal to the count value of the expected position, the relay controlling the curtain controller is disconnected, and the curtain controller controls the motor to meet the user's expectations position, if the two are not equal, then continue to control the count value of the historical position according to the clock of the curtain controller and the running direction of the curtain.

(7) If the user changes the desired position of the curtain before reaching the desired position, repeat steps (2) to (6).

Beneficial effects of the present invention: the control method of the curtain controller used in the present invention improves the traditional operations of raising-stopping (opening-stopping) and lowering-stopping (closing-stopping), and avoids frequent operations on the curtains , after the user operates, there is no need to wait for the curtain to reach the set position before stopping the curtain. This method does not depend on the structure of the curtain controller or the use of sensors to detect the position of the curtain. It can be implemented from the software, reducing the cost of the curtain controller. cost and complexity.

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
