Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliance control, and in particular to a curtain motor with electrical appliance control. Background Art

[0002] Among the many application scenarios of smart homes, owners want to increase electrical appliance control (such as controlling air conditioners, televisions, humidifiers, air purifiers and other electrical appliances), and most household appliances have infrared remote controls. Although each home appliance manufacturer has an APP based on WIFI control and the WIFI protocol is not open to the public, most of them have infrared remote control functions. In this case, smart home manufacturers in the industry, whether using wired or wireless technology architectures, need to add separate desktop or ceiling-mounted infrared control devices. By learning the infrared code of the infrared remote control of the home appliance, the system controls the appliance by transmitting the learned infrared control code of the controlled electrical appliance through the desktop or ceiling-mounted infrared controller. Affected by the installation environment (for example, the ceiling-mounted infrared controller cannot be installed without a ceiling, and the desktop infrared controller cannot be powered without a convenient power socket nearby. As a movable device, the desktop infrared controller does not have stable output and normalized electrical appliance control functions), it is impossible for customers to recognize it as a product that can increase the function of electrical appliance control and is suitable for various installation environments and application scenarios.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Please also read Figures 1 to 17 Now, a specific implementation of a curtain motor with electrical control provided by the present invention is described. The curtain motor with electrical control includes:

[0053] Motor body;

[0054] A main control module disposed on the motor body;

[0055] An infrared control unit disposed on the motor body and communicatively connected to the main control module;

[0056] The main control module is used to obtain a control signal and transmit the control signal to a preset controlled electrical appliance through the infrared control unit; wherein the control signal is an infrared code; the pin of the chip inside the main control module is electrically connected to the pin of the infrared control unit. Fig. 9 and Fig.10 , pins 50, 51, 52 of the main control chip are electrically connected to pins 5, 6, 7 of the infrared chip.

[0057] Specifically, the motor body is the core power part of the curtain motor, which provides power for the opening, closing, lifting and other actions of the curtain. Its performance directly affects the smoothness, speed and noise of the curtain operation. For example, a high-performance motor can ensure that the curtain runs smoothly without any jamming or jittering, and can adjust different speeds according to user needs, such as slowly opening or quickly closing the curtain. At the same time, low-noise design is also an important feature of the motor body. During operation, it will not generate too much noise that interferes with the living environment, ensuring a quiet and comfortable home environment.

[0058] The main control module is installed on the motor body and is the control core of the curtain motor. It undertakes many important functions. It is equivalent to the "brain" of the curtain motor and is responsible for the coordination and control of the entire system.

[0059] Signal reception and processing: The main control module can receive control signals from different sources, including signals from wired communication interfaces (such as RS485, KNX, power carrier, etc.) or wireless communication modules (such as WiFi, RF, Zigbee, Bluetooth, etc.). These signals contain the user's operating instructions for the curtain motor and the controlled electrical appliances. The main control module will parse and process these instructions to determine the corresponding operating actions. For example, when receiving a command to control the opening and closing of the curtains sent by the mobile phone software through the Zigbee gateway, the main control module can accurately identify and convert it into a specific signal for the motor drive.

[0060] Control command distribution: After processing the received control signal, the main control module will distribute the command according to the type and purpose of the signal. For the operation command of the curtain motor itself, such as controlling the opening, closing, and stopping of the curtain, the main control module will pass the corresponding command to the motor drive unit to drive the motor to perform the corresponding action; for the command to control the electrical appliance, the main control module will pass it to the infrared control unit, and the infrared control unit will then convert the command into an infrared code that can be recognized by the electrical appliance for transmission control.

[0061] The infrared control unit is set on the motor body and communicates with the main control module. It is a key part to realize the electrical control function. Its main function is to receive the electrical control signals from the main control module (these signals have been parsed and processed in the main control module), and convert them into corresponding electrical infrared codes, and then transmit them through the infrared transmitter. For example, when the main control module sends a command to control "TV on", the infrared control unit will convert the command into the infrared power-on code corresponding to the TV, and transmit it through the infrared transmitter, thereby realizing the power-on control of the TV.

[0062] The overall workflow is as follows: When the user issues a control instruction through a preset terminal (such as a mobile phone software), the main control module receives the instruction through the corresponding communication interface (wired or wireless). If it is an instruction to control the curtain motor itself, the main control module directly drives the motor drive unit to make the motor body perform the corresponding curtain action; if it is an instruction to control an electrical appliance, the main control module sends the instruction to the infrared control unit, and the infrared control unit converts the instruction into an electrical appliance infrared code and transmits it through the infrared transmitter head, thereby realizing the control of the preset controlled electrical appliance. For example, if the user wants to turn on the air conditioner and open the curtains in the living room, he sends the corresponding instruction through the smart home control software on the mobile phone. The instruction is first sent to the main control module of the curtain motor. The main control module sends the "open the curtain" instruction to the motor drive unit and the "turn on the air conditioner" instruction to the infrared control unit. The infrared control unit converts it into the infrared power-on code of the air conditioner and transmits it, realizing the synchronous operation of opening the curtains and turning on the air conditioner.

[0063] Specifically, the infrared control unit includes an infrared emitting head; the infrared emitting head is used to be arranged toward the direction of the controlled electrical appliance. The infrared emitting head is a universal emitting head. The number of the infrared emitting heads is 1 or at least two.

[0064] The infrared transmitter plays a key role in signal transmission in the entire curtain motor system with electrical control. It transmits the electrical control signal (converted into infrared code form) transmitted by the main control module to realize remote control of the controlled electrical appliances. Specifically, when the main control module receives the command to control the electrical appliance and converts it into the corresponding infrared code, these infrared code signals are radiated to the surrounding space through the infrared transmitter, forming an infrared signal beam, which is received by the infrared receiving device on the target controlled electrical appliance, so that the electrical appliance performs the corresponding operation. For example, when the user issues a command to control "TV channel change", the infrared code for TV channel change after a series of processing is transmitted through the infrared transmitter, and after being received by the infrared receiver of the TV, the TV completes the channel change action.

[0065] The universal transmitter design enables the infrared transmitter to flexibly adjust the transmission angle in multiple directions. In an actual home environment, the placement of electrical appliances may vary, and may change with changes in furniture layout or usage requirements. The universal transmitter can manually adjust its direction to ensure that the infrared signal can accurately point to the controlled appliances in various positions. Whether the appliance is directly in front of the curtain motor, on the side or at other angles, effective signal transmission can be achieved, greatly improving the flexibility and reliability of infrared control. For example, in a living room, the air conditioner may be installed in a corner, while the humidifier may be placed on a coffee table. By adjusting the direction of the universal infrared transmitter, it is easy to control these two appliances in different positions at the same time.

[0066] Furthermore, when the number of infrared transmitters is 1, in a relatively simple home environment, if the electrical appliances are relatively concentrated and there are not too many obstacles blocking them, one infrared transmitter can meet the basic electrical appliance control needs. For example, in a small bedroom, there is only one air conditioner and one TV, and they are relatively close to the curtain motor. A well-performing universal infrared transmitter can effectively control these two appliances. By reasonably adjusting the direction of the infrared transmitter so that it can cover the infrared receiving area of ​​the air conditioner and TV, the switching, adjustment and other operations of these two appliances can be realized.

[0067] When there are at least two infrared transmitters, the signal coverage can be further expanded, the accuracy and reliability of control can be improved, and it is suitable for more complex home environments or control scenarios of more electrical appliances. Multiple infrared transmitters can simultaneously transmit infrared signals from different directions, which increases the possibility of signals reaching the controlled electrical appliances and reduces the probability of control failure due to signal blocking or reflection. For example, in a large living room, there are multiple electrical appliances such as air conditioners, televisions, projectors, and air purifiers, and they are distributed in different corners. At this time, two or more infrared transmitters are set up, and their directions can be adjusted respectively to provide special signal coverage for electrical appliances in different areas. For example, one infrared transmitter is facing the corner where the air conditioner and air purifier are located, and the other infrared transmitter is facing the area where the TV and projector are located. This ensures that each electrical appliance can stably receive the infrared control signal and achieve more comprehensive and accurate electrical appliance control. At the same time, multiple infrared transmitters can also achieve redundant backup of signals to a certain extent. When the signal of an antenna is interfered with or fails, other infrared transmitters can still ensure the control of some or all electrical appliances, thereby improving the stability of the entire system.

[0068] In some embodiments, the main control module includes: a control signal receiving module, a control mainboard and a driving circuit;

[0069] The control signal receiving module is used to receive a first control instruction sent by a preset terminal;

[0070] The driving circuit is used to drive the motor body;

[0071] The control main board is connected to the control signal receiving module and the driving circuit respectively, and is used to drive the motor body to execute an action matching the first control instruction through the driving circuit based on the first control instruction.

[0072] In these embodiments, the components of the main control module work together to achieve precise control of the curtain motor, which is described in detail below:

[0073] The control signal receiving module, as an interface for communicating with external devices, is responsible for receiving the first control instruction sent by the preset terminal. The preset terminal can be in various forms, such as smart home control applications on smartphones, smart remote controls, smart gateways, etc. It can receive command signals transmitted from these terminals through wired (such as RS485, KNX, power carrier, etc.) or wireless (such as WiFi, radio frequency, Zigbee, Bluetooth, etc.) communication methods. For example, when a user clicks the "Open Curtains" button through the smart home APP on the mobile phone, the mobile phone will send the corresponding control instructions to the control signal receiving module of the curtain motor through wireless communication (such as WiFi or Zigbee). It is a key link in realizing the user's remote control of the curtain motor, enabling the curtain motor to interact with the external control device to receive the user's operation intention. By supporting multiple communication methods, the compatibility and flexibility of the system are increased. Users can choose the most suitable control method according to their home environment and device configuration, and easily integrate the curtain motor into the smart home ecosystem.

[0074] The drive circuit provides the necessary power and drive signal to the motor body so that the motor can operate in a predetermined manner. According to the instructions of the control motherboard, it converts the input power into the current and voltage form suitable for the operation of the motor, and controls the parameters such as the rotation direction, speed and torque of the motor. For example, when the control motherboard issues the "curtain open" instruction, the drive circuit will provide a positive current to the motor, so that the motor rotates at the set speed and torque, drives the pulley on the curtain track, and realizes the opening action of the curtain; conversely, when receiving the "curtain close" instruction, the drive circuit will change the direction of the current, reverse the motor, and close the curtain. The motor body requires precise drive to achieve smooth and reliable operation, and the performance of the drive circuit directly affects the overall performance of the curtain motor. A good drive circuit can ensure that the motor can work normally under different load conditions (such as the weight of the curtain, the resistance difference caused by different materials), and can also realize the protection functions of the motor, such as overcurrent protection, overheating protection, etc., to prevent the motor from being damaged due to abnormal conditions and extend the service life of the motor.

[0075] As the core of the main control module, the control mainboard is responsible for parsing and processing the first control instruction received by the control signal receiving module. It will identify the meaning and type of the instruction according to the pre-set program and algorithm, and make corresponding decisions according to the content of the instruction. For example, when the instruction received is "open the curtain to 50% position", the control mainboard will calculate the number of steps or angles that the motor needs to rotate, as well as the corresponding speed and torque parameters, so that the curtain can be accurately opened to the specified position. In the whole process, the control mainboard plays the role of coordinating the work of the control signal receiving module and the drive circuit. It converts the user instructions from the control signal receiving module into a drive signal that the drive circuit can understand and execute. At the same time, it can also monitor the running status of the motor (such as through sensor feedback on the motor) and adjust and optimize according to the actual situation. For example, if an obstacle is encountered during the opening of the curtain, causing the motor load to suddenly increase, the motor speed may drop. At this time, the control mainboard can timely adjust the output of the drive circuit through the monitored motor current or speed changes, increase the torque of the motor, so that the curtain can overcome the obstacle and continue to run, or stop the motor when necessary to avoid damage to the motor and curtain system. This coordinated control capability ensures that the curtain motor can accurately and stably execute the user's control instructions, while also having certain intelligence and adaptive capabilities, improving the reliability of the entire system and user experience.

[0076] In some embodiments, the control mainboard is also connected to the infrared control unit;

[0077] The control signal receiving module is used to receive a second control instruction sent by a preset terminal; the control mainboard is used to send a control signal matching the second control instruction through the infrared control unit based on the second control instruction.

[0078] First, the control signal receiving module receives the second control instruction sent by the preset terminal. Similar to the first control instruction previously received to control the action of the curtain motor, the second control instruction can also come from a variety of preset terminals, such as smart home apps, smart remote controls, or other control devices connected to the smart home system. These terminals convey the user's control intentions for electrical equipment to the control signal receiving module through wired or wireless communication. For example, when a user clicks the "Turn on air conditioning" button on a mobile phone app, the phone will send the corresponding control instruction to the control signal receiving module of the curtain motor.

[0079] Once the control signal receiving module receives the second control instruction, it will pass the instruction to the control main board to prepare for subsequent processing.

[0080] After receiving the second control instruction, the control motherboard will analyze it in depth. It understands the specific meaning of the instruction based on the pre-stored instruction code table or algorithm, such as determining whether to control the switch of the air conditioner, adjust the temperature, or control the channel switching and volume adjustment of the TV. Then, the control motherboard will generate a control signal that matches the instruction content. These control signals are in a format specially designed for the infrared control unit so that they can be subsequently converted into infrared codes that can be recognized by the appliance. For example, if the instruction is "set the air conditioner to 26 degrees", the control motherboard will generate a control signal containing the temperature setting information and prepare to send it to the infrared control unit.

[0081] The control mainboard transmits the generated control signal to the infrared control unit, instructing the infrared control unit to perform the operation of transmitting infrared codes. After receiving the control signal, the infrared control unit uses its internal circuits and algorithms to convert the control signal into the corresponding electrical infrared code. These infrared codes are generated according to the infrared remote control protocols of different electrical equipment, with specific coding formats and pulse sequences, and can be accurately recognized by the target electrical equipment. For example, for the control of the air conditioner, the infrared control unit will convert the temperature setting information into the infrared code format corresponding to the air conditioner, and then transmit it through the infrared transmitter. After receiving the infrared code, the air conditioner parses the instructions in the infrared code according to its internal program, and then performs the corresponding temperature setting operation.

[0082] Specifically, the control signal receiving module includes a wired communication interface and / or a wireless communication module; the wired communication interface is used to communicate with a preset terminal through a communication line; the wireless communication module is used to communicate with a preset terminal by wireless communication. The wired communication interface includes: a power carrier line interface, a KNX bus interface and / or an RS485 bus interface. The wireless communication module includes a WiFi communication module, a radio frequency communication module, a power carrier module, a zigbee module and / or a Bluetooth Mesh module.

[0083] The various communication interfaces and module designs of the control signal receiving module provide a variety of connection methods for curtain motors with electrical control, enabling them to flexibly adapt to different smart home systems and user needs. The following is a detailed introduction:

[0084] The wired communication interface enables the curtain motor to connect and communicate with other components of the smart home system through physical lines.

[0085] Specifically, KNX is an international standard communication protocol widely used in the field of smart home, with high reliability, stability and interoperability. It adopts a distributed control structure, supports multiple devices to communicate in the same network, and can realize complex automation control scenarios. For example, in large commercial buildings or high-end residences, curtain motors, lighting systems, air conditioning equipment, etc. in multiple rooms can be connected to a control system through the KNX bus to achieve centralized management and intelligent linkage control. For curtain motors, the use of KNX bus interface can be easily integrated into the smart home system based on the KNX protocol. Users can control curtain motors through control panels, sensors or other smart devices in the KNX system, and curtain motors can also be linked with other KNX devices. For example, when the light sensor detects that the indoor light is too strong, it sends a signal to the curtain motor through the KNX bus to automatically control the curtain to close; or when linked with the access control system, the curtains are automatically opened when the door is opened.

[0086] RS485 is a commonly used industrial communication standard with advantages such as long transmission distance (up to kilometers) and strong anti-interference ability. It uses differential signal transmission and can work stably in complex electromagnetic environments. In smart home applications, the RS485 bus can connect multiple devices to form a network to achieve reliable data transmission. After the curtain motor is equipped with an RS485 bus interface, it can communicate and connect with other smart home devices that use RS485 communication. For example, in some villas or large residences, security systems and smart lighting systems based on RS485 buses may have been deployed. The curtain motor can access the system through the RS485 bus, share information with other devices, and realize more intelligent control logic. For example, when the security system is in the armed state, the curtain motor can automatically close the curtains according to preset rules to improve home security.

[0087] WiFi is the most popular wireless network technology in modern homes. Almost all smartphones, tablets and smart home appliances support WiFi connection. After the curtain motor is equipped with a WiFi communication module, users can directly use the smart home APP on their mobile phones to control the curtain motor through the home WiFi network without the need for additional gateway devices (if the mobile phone and the curtain motor are on the same WiFi network). This convenience allows users to control the curtains anytime and anywhere, whether at home or remotely through the mobile phone when away. The WiFi communication module can establish a stable connection with the home wireless router to achieve high-speed data transmission. It can receive control instructions from the APP and feedback the status information of the curtain motor (such as curtain position, motor operation status, etc.) to the APP, so that users can understand the working status of the curtain motor in real time. For example, the user controls the opening of the bedroom curtains through the mobile phone APP in the living room. After receiving the instruction, the WiFi communication module passes it to the control mainboard to execute the operation, and at the same time, the status information of the curtain motor after execution (such as the curtain has been opened to the specified position) is fed back to the mobile phone APP through the WiFi network and displayed to the user.

[0088] The power carrier module can realize data transmission through power lines without additional wiring, which reduces costs. It has a wide coverage range, can cover the entire power supply area, and has a high data transmission rate, which is faster than traditional wireless communication technology. In the smart home system, power carrier communication can be used to achieve interconnection between smart appliances. Through the power lines inside the home, smart devices can communicate with each other to achieve functions such as remote control and timer switching.

[0089] RF communication technology is easy to use, low cost and relatively low power consumption. It does not require complex network configuration like WiFi, and is suitable for some smart home application scenarios that are cost-sensitive or have low power consumption requirements. RF communication modules usually operate in specific frequency bands, such as 433MHz, 868MHz, etc. These frequency bands have good penetration capabilities within a certain range, and once the RF switch is powered, it will have a long connection, which can achieve relatively stable communication in the home environment. Users can use RF smart switches to control curtain motors. RF smart switches are simple to operate and can send control signals by pressing a button. This method is very practical in some scenarios that do not require remote Internet control or do not require high control distance, such as controlling the opening and closing of curtain motors in local areas (such as a single room) inside the home. At the same time, the RF communication module can also communicate with other RF devices to achieve simple linkage control, such as linkage with RF door magnetic sensors to automatically close curtains when the door is opened.

[0090] Zigbee is a low-power, low-rate wireless communication technology designed for short-range, low-power wireless devices. It has excellent self-organizing network capabilities. Multiple Zigbee devices can automatically form a network, and the devices in the network can communicate and collaborate with each other. In smart home systems, Zigbee modules are often used to connect various sensors, switches, and small electrical appliances to form a stable wireless sensor network. After the curtain motor is equipped with a Zigbee module, it can be intelligently linked with other Zigbee devices. For example, when used with a Zigbee human infrared sensor, when the sensor detects that there is no one in the room and after a period of time, the Zigbee module can receive the sensor's signal and notify the control motherboard to control the curtain motor to automatically close the curtain, achieving energy saving and privacy protection. At the same time, the gateway device in the Zigbee network can forward the control instructions of the curtain motor from the Internet or other networks, and users can also connect to the Zigbee gateway through a mobile phone APP or other smart terminals to remotely control the curtain motor.

[0091] Bluetooth technology is mainly used for short-distance device connection (generally about 10 meters), with the characteristics of simple pairing and fast connection speed. In smart home applications, the Bluetooth module can realize the quick connection of curtain motors with nearby smart devices (such as smartphones, tablets or smart speakers). After the user pairs the curtain motor with the mobile phone Bluetooth, he can use the relevant application on the mobile phone to control the curtain motor, which is convenient and fast to operate. With the popularity of intelligent voice assistants (such as Siri, Xiao Ai, Xiaodu, etc.), the Bluetooth module can also integrate the curtain motor with the voice control system. Users can control the action of the curtain motor through voice commands (such as "open the curtain") without manually operating the mobile phone or other control devices. This voice control method provides users with a more convenient and natural interactive experience, which is very practical when both hands are busy or it is inconvenient to operate the mobile phone. At the same time, the Bluetooth module can also be linked with other Bluetooth-enabled smart devices (such as smart lights, smart door locks, etc.) for scene linkage, and through preset scene modes (such as "home mode" and "sleep mode", etc.), multiple devices can work together to create a more comfortable and intelligent home environment.

[0092] Furthermore, the curtain motor with electrical control also includes:

[0093] A motor driving unit, used to cooperate with the motor and adjust the state of the curtain under the drive of the motor; a curtain position detection unit connected to the control main board, used to detect the curtain position and send the detection result to the control main board;

[0094] The motor drive unit is the key part to realize the actual movement of the curtain. It works closely with the motor to convert the motor's rotational motion into specific actions such as opening and closing, lifting and lowering of the curtain. When the motor receives the power and drive signal from the drive circuit and starts to rotate, the motor drive unit is connected to the curtain track system through a transmission device (such as a belt, chain or gear, etc.) to drive the curtain to move on the track. For example, in electric opening and closing curtains, the motor drive unit will control the opening and closing direction of the curtain according to the forward and reverse rotation of the motor, and control the opening and closing speed of the curtain by adjusting the motor speed, so that the user can accurately adjust the state of the curtain.

[0095] The curtain position detection unit connected to the control mainboard is used to detect the curtain position and send the detection result to the control mainboard; the control mainboard protects the motor body based on the detection result.

[0096] The curtain position detection unit uses various sensor technologies to monitor the position information of the curtain in real time. Common detection methods include Hall sensors, photoelectric sensors or rotary encoders. For example, the Hall sensor uses the principle of magnetic field changes to install magnetic strips on the curtain track. When the curtain moves, the Hall sensor installed on the motor drive unit or the curtain will detect the change in the magnetic field to determine the position of the curtain; the photoelectric sensor determines the position of the curtain by emitting and receiving light to determine whether the curtain blocks the light; the rotary encoder is connected to the motor shaft and calculates the movement distance and position of the curtain by measuring the rotation angle and number of turns of the motor.

[0097] The detected curtain position information will be sent to the control mainboard in real time. The control mainboard can realize a variety of intelligent control functions based on these feedback information, and can also effectively protect the motor body. In terms of intelligent control, when the user sets the curtain to open to a specific position (such as 50% opening) through the preset terminal, the control mainboard will accurately control the rotation of the motor according to the feedback information of the curtain position detection unit until the curtain reaches the specified position and stops the motor. In terms of motor protection, if the curtain encounters an obstacle during operation and cannot move normally, the curtain position detection unit will detect that the curtain position is abnormal and send the information to the control mainboard. The control mainboard will immediately stop the motor to prevent the motor from being damaged due to overload. In addition, when the curtain is fully opened or closed, the position detection unit will also promptly notify the control mainboard to stop the motor from running to avoid damage caused by long-term motor blocking, thereby extending the service life of the motor and ensuring the reliability of the entire curtain motor system.

[0098] The power module is used to power the curtain motor with electrical control; the power module includes an A / D conversion module, which is used to convert AC power into DC power to power the curtain motor with electrical control. The power module provides the necessary power for the entire curtain motor with electrical control to ensure that the motor, control motherboard, infrared control unit, motor drive unit, curtain position detection unit and other components can work normally. It is the power source for the operation of the curtain motor, introducing and distributing the external power supply to each part that needs electricity to maintain the stable operation of the entire system. For example, in a home environment, the power module can connect the mains (AC power) to provide a stable power supply for the electronic components and motor inside the curtain motor, so that the curtain motor can respond to the user's control instructions at any time, execute the opening and closing action of the curtain and the infrared control function of the electrical equipment. The A / D conversion module (analog-to-digital conversion module) in the power module undertakes the important task of converting AC power into DC power. The mains power is usually AC power, and most of the electronic components and chips inside the curtain motor require DC power to work normally. The A / D conversion module rectifies, filters and stabilizes the input AC power, converting it into DC power that meets the working requirements of the curtain motor components. For example, the 220V AC power is converted into 5V, 12V or other suitable voltage DC power to provide a stable power supply for the microprocessor, sensor, communication module, etc. on the control motherboard, and also provides a suitable DC drive voltage for the motor drive unit to ensure that the motor can operate normally. This AC to DC conversion process is one of the key functions of the power module. It ensures that the curtain motor system can operate safely and stably in a home power environment. It also helps to improve the system's anti-interference ability, reduce the impact of power fluctuations on electronic components, and further improve the performance and reliability of the curtain motor.
