The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. The components of embodiments of the present disclosure generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely to indicate selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present disclosure.

It should be noted that similar reference numerals and letters indicate similar items in the following drawings, so once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings. Meanwhile, in the description of the present disclosure, the terms “first”, “second”, and the like are only used to distinguish descriptions, and cannot be understood to indicate or imply relative importance.

As shown in FIG. 1, an embodiment of the present invention provides a curtain control method, which is applied to a curtain control system. The curtain control system includes a curtain control device and a smart terminal. The smart terminal is communicatively connected with the curtain control device. The curtain control device is configured to control the movement of the curtain according to a control instruction sent by the smart terminal. The curtain control device includes a processor, a first communication unit, and a driving motor. The smart terminal includes a second communication unit, an input unit, and a control chip. The method includes the following steps.

Step S101: The second communication unit establishes a communication connection with the first communication unit.

Before controlling the curtain control device, the smart terminal needs to establish a communication connection with the curtain control device. The smart terminal establishes a communication connection with the first communication unit in the curtain control device through the second communication unit. The first communication unit and the second communication unit can communicate based on the same communication protocol, for example, they can communicate through the Bluetooth protocol or be in the same local area network.

Step S102: During the communication connection between the second communication unit and the first communication unit, the input unit receives a limit instruction for the curtain controller, where the limit instruction includes a maximum ascent height of the curtain and / Or the lowest descent height.

After the second communication unit establishes a communication connection with the first communication unit, the user can input a limit instruction through the smart terminal. In the embodiment of the present application, the curtain can be raised or lowered under the control of the curtain control device. If it continues to fall, the curtain control equipment will continue to work, and it is easy to cause damage to the equipment. The user can beat the smart terminal to input the position where the curtain is highest raised or the position where the curtain is lowered the most.

There are two ways to set the highest ascent or the lowest ascent. One is that the user directly inputs a height value through the smart terminal, and uses the height value as the highest ascent or the lowest ascent. The other is that, during the setting process, the user continuously inputs a control instruction, and when the control instruction stops, the height of the curtain is set to the highest ascent or the lowest ascent.

In detail, in the process of communication connection between the smart terminal and the curtain control device, in order to avoid the interruption of communication, the setting fails. As shown in Figure 2, the following methods can also be used to avoid setting failure.

Step S121: The control chip generates a first character string.

The control chip can generate a string of random characters as the first string. For example, a string of "11111 ..." can be generated, that is, the control chip continuously sends characters to the curtain control device during the communication connection between the smart terminal and the curtain control device. 1".

In step S122, the second communication unit sends the first character string to the first communication unit at a preset period during communication with the first communication unit.

The second communication unit may transmit the first character string generated by the control chip to the first communication unit in a preset period or continuously. The first character string is used as an identifier for the normal communication connection between the smart terminal and the curtain control device. During the process of setting the highest ascent or the lowest ascent, and without determining that the setting has been successfully set, if the first communication unit is within a predetermined time If the first string is not received, it indicates that there is an abnormality in the communication connection between the smart terminal and the curtain control device. At this time, the driving motor that is in motion can be controlled to stop running to avoid the abnormal situation.

In step S123, after receiving the limit instruction and determining the highest rising height and / or the lowest falling height corresponding to the limit instruction, the processor generates limit success information.

After the processor receives the limit instruction, it can process the height information contained in the limit instruction. When inputting the limit command, the user can continuously input two height values, and the two height values are different. The value with a larger height value is regarded as the highest ascending height, and the value with a smaller height value is regarded as the lowest fall. height. After the setting is successful, the processor can generate a limit success message.

In step S124, the first communication unit sends the limit success information to the second communication unit.

In step S125, the control chip stops generating the first character string after receiving the limit success information through the second communication unit.

After the limit is successful, the control chip can stop generating the first character string after receiving the limit success message sent by the processor, and the setting process ends.

Step S103, the second communication unit sends the limit instruction to the first communication unit, so that the processor determines the highest rising height and / or the lowest falling of the curtain according to the limit instruction. height.

During the communication between the smart terminal and the curtain control device, when the communication connection between the second communication unit and the first communication unit is disconnected, the processor determines whether the limit instruction is received; the processor determines whether the received limit instruction is received. When the limit instruction is incomplete, the processor controls the driving motor to stop running.

In the case of a communication terminal, the limit setting process is aborted. After the user uses the smart terminal to establish a communication connection with the curtain control device next time, it is necessary to first determine whether the limit setting is successful, and if the previous limit setting is not successful, perform the limit setting again.

It can be understood that the communication connection between the smart terminal and the curtain control device may be artificially suspended, or it may be due to a network failure or the like. When the second communication unit is communicating with the first communication unit, when the input unit receives a disconnection instruction, the second communication unit disconnects the communication connection with the first communication unit; the processing The controller controls the driving motor to stop running. As long as the curtain control device does not generate a setting success message, it indicates that the setting process has not been completed.

In detail, it can be set by the following sub-steps.

Sub-step S131, the input unit receives a continuous rising instruction or a continuous falling instruction.

The user inputs a continuous rising instruction or a continuous falling instruction through the input unit. Understandably, the highest rising height of the curtain is higher than the lowest falling height. The smart terminal can be configured or displayed with a rising button and a falling button. When the rising button is pressed, a continuous rising instruction is generated, and when the falling button is pressed, a continuous falling instruction is generated. When the up button or down button is released from the pressed state, the smart terminal generates a stop instruction.

Sub-step S132, the second communication unit sends the continuous rising instruction or continuous falling instruction to the first communication unit.

The smart terminal can send relevant instructions to the curtain control device.

Sub-step S133, the processor controls the driving motor to continuously raise the curtain according to the continuous rising instruction; or the processor controls the driving motor to continuously cause the curtain according to the continuous falling instruction decline.

The processor in the curtain control system can control the driving motor to run. The driving motor can drive the curtain to perform corresponding actions.

Sub-step S134, the input unit receives a stop instruction;

At the moment when the up button or down button on the smart terminal is pressed to released, it indicates that the user does not want the curtain to continue to rise or continue to fall, and the input unit generates a stop instruction at this time.

Sub-step S135, the second communication unit sends the stop instruction to the first communication unit.

In sub-step S136, the processor determines the current state of the curtain according to the stop instruction.

Sub-step S137, when the curtain is continuously rising, setting the current height to the highest rising height;

In step S138, when the curtain is continuously lowered, the current height is set as the lowest lowered height.

After receiving the stop instruction, the curtain control device can set the limit height according to the time point when the stop instruction is received. When the curtain is continuously rising, the current height is set to the highest rising height. When the curtain is continuously lowered, the current height is set to the lowest lowered height.

In another specific implementation manner, as shown in FIG. 3, after the step of establishing a communication connection with the first communication unit by the second communication unit, the method further includes the following steps.

In step S104, the processor determines whether a limit height is set.

After the intelligent terminal communicates with the curtain control device, it is necessary to first determine whether the limit height setting process has been performed. If the limit height setting has not been performed, or a communication interruption occurred during the previous setting process If there is an abnormal situation, but the limit height is not set successfully, the limit height needs to be set again. If you have already set the limit height, you do not need to enter the height setting process.

In step S105, when the processor determines that the limit height is not set, the processor sends a setting instruction to the second communication unit through the first communication unit.

In step S106, when the control chip receives the setting instruction through the second communication unit, it generates a prompting instruction to prompt the smart terminal to set the limit height.

After determining that the smart terminal has not set the limit height of the curtain control device, the control chip can control the smart terminal to display the limit flow page, prompting the user to enter the limit height setting process by operating the smart terminal.

Sending the limit instruction to the first communication unit at the second communication unit, so that the processor determines, according to the limit instruction, the maximum height of the curtain and / or the minimum height of the curtain After the steps, as shown in FIG. 4, the method further includes the following steps.

In step S107, the input unit receives a rising or falling instruction input from the outside.

In step S108, the second communication unit sends the rising or falling instruction to the first communication unit.

In step S109, the processor controls the driving motor to cause the curtain to rise or fall according to the rising or falling instruction.

In step S110, when the processor determines that the curtain is raised to the highest rising height, or when it is determined that the curtain is lowered to the lowest falling height, the processor controls the driving motor to stop running.

As described above, the process of setting the highest ascent and the lowest ascent can be achieved by two methods. The above describes the setting of the highest ascent and the lowest descent by directly giving two height values. In addition, during the communication connection between the smart terminal and the curtain control device, the user inputs a rising or falling instruction through the input unit of the smart terminal. After the input is stopped, the smart terminal generates a stop instruction, and the curtain control device sets a limit when the stop instruction is generated. Bit height.

In actual use, the user can control the curtain to rise or fall through the intelligent terminal. The processor controls the driving motor to continue to run according to the received control instructions. The drive motor drives the curtain to continue to rise or fall. During the curtain's continuous rise or fall, The processor may determine the current height of the curtain according to the corresponding relationship between the predetermined running height of the driving motor and the current height of the curtain, and when the curtain rises to the highest rising height set by the above setting method, or drops to the above When the minimum descent height set by the setting method, the drive motor can be controlled to stop running.

In summary, the curtain control method provided by the present disclosure can set the highest rising height or the lowest falling height of the curtain, and the limit height of the curtain can be set through the intelligent terminal, which can prevent the curtain from exceeding the limit during operation. The height of the motor and damage the drive motor. The intelligent terminal is used to control the curtains with clear control logic and high control efficiency.
