[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] The embodiments of the present invention provide a door opener control system that detects relevant information of the door leaf and within a preset range through an induction module and controls the opening and closing of the door accordingly to achieve the effects of improving the safety, flexibility, and intelligence level of the door opener control system.

[0057] According to an embodiment of the present invention, a door opener control system is provided, as Figure 1 shown, the control system includes: a main control module 1, an induction module 2, a door opening motor module 3, and a clutch module 4.

[0058] As Figure 1 shown, the induction module 2, which is connected to the main control module 1, is used to detect the angle information of the door leaf and whether there are people or objects within a preset range, and transmit the detection results to the main control module 1.

[0059] Specifically, the induction module 2 determines the current state of the door leaf by detecting the angle information of the door leaf, and accordingly determines a preset range. By detecting whether there are people or objects within the preset range, it determines whether there is a risk of people or objects being pinched. The preset range can be a preset distance in the direction perpendicular to the door leaf, which is only an example and not limited thereto.

[0060] Optionally, the induction module may include: a distance sensor, a camera, an angle sensor, which are only examples and not limited thereto.

[0061] It should be noted that the models of the distance sensor, camera, and angle sensor are not restricted and can be any model on the market. The function of the distance sensor is to detect the distance from itself to an obstacle. When the detected distance is less than the preset threshold, it indicates that there is an obstacle within the preset range and outputs a low level; when the detected distance is not less than the preset threshold, it indicates that there is no obstacle within the preset range and outputs a high level. The function of the camera is to monitor whether there are people or objects in the captured image. When there are people or objects, it outputs a low level; when there are no people or objects, it outputs a high level. At the same time, the captured image is visually displayed to facilitate a more accurate grasp of the actual situation within the preset range. The function of the angle sensor is to detect the angle of the door leaf and determine the preset range based on the door leaf angle.

[0062] As Figure 1 shown, the main control module 1, which is connected to the external door lock, is used to receive the door opening signal from the external door lock and control the operation of the door opening motor module 3 and the clutch module 4 according to the door opening signal and the detection result of the induction module 2.

[0063] Specifically, the main control module 1 can be a single-chip microcomputer or other control chips, which have the functions of receiving, processing signals and sending control instructions. The main control module 1 is connected to the external door lock. The intelligent lock unlocks by recognizing faces, fingerprints, passwords, IC cards, etc. When the intelligent lock recognizes the correct unlocking information, the lock tongue of the external door lock reaches the unlocking position and sends a door opening signal to the main control module 1. The communication method between the external door lock and the main control module 1 can be RS485, which is only an example and not limited thereto. After receiving the door opening signal, the main control module 1 controls the operation of the door opening motor module 3 and the clutch module 4 according to the detection result of the induction module 2. When the detection result is that there are no people or objects within the preset range, the door opening motor module 3 and the clutch module 4 cooperate to operate to open the door leaf. When the detection result is that there are people or objects within the preset range, the door opening motor module 3 and the clutch module 4 do not operate and the door leaf does not open, avoiding pinching people or objects during the process of opening and closing the door.

[0064] It should be noted that there is a logical control relationship between input and output inside the main control module. For example, when a low level is input at the input terminal, the output terminal is also controlled to output a low level. That is, when a low level is input by either the distance sensor or the camera, neither the door opening motor module nor the clutch module connected to the output terminal of the main control module will operate. This is only an example and not limited thereto.

[0065] As Figure 1 shown, the door opening motor module 3 is connected to the main control module 1 and is used to open or close the door according to the first instruction of the main control module 1.

[0066] Specifically, the door opening motor module 3, as an execution module of the door opening machine control system, is used to drive the door leaf to move according to the first instruction of the main control module 1, and the first control instruction includes making the door leaf open or close.

[0067] It should be noted that the function of the door opening motor module is to automatically open and close the door. When a low level is input to it, the door opening motor module does not operate. When a high level is input to it, the door opening motor module operates to open or close the door. This is only an example and not limited thereto. For the control of the door opening motor module, existing motor control methods can be used and will not be elaborated here.

[0068] As Figure 1 shown, the clutch module 4 is connected to the main control module 1 and is used to control the engagement and disengagement of the door opening motor module 3 and the clutch module 4 according to the second instruction of the main control module 1.

[0069] Specifically, the clutch module 4, as an auxiliary execution module of the door opening machine control system, when it is engaged with the door opening motor module 3, the door opening motor module 3 can drive the door leaf to move. When the clutch module 4 is disengaged from the door opening motor module 3, the door opening motor module 3 cannot drive the door leaf to operate.

[0070] The position of the clutch module is within a preset distance from the door opening motor module, and the preset distance can enable the clutch module to be disengaged or engaged with the door opening motor module. Its working principle is the same as that of the existing automotive clutch and will not be elaborated here.

[0071] The door opening machine control system provided in this embodiment obtains the detection information of the current door leaf through the sensing module 2, and the main control module 1 controls the opening or closing of the door leaf according to the detection information, improving the flexibility and intelligence level of the door opening machine control system. By detecting whether there are people or objects in the preset area, it avoids people or objects being clamped by the door leaf, improving the safety of the door opening and closing process.

[0072] In some alternative embodiments, as Figure 2 shown, the sensing module 2 includes: an angle sensor 21, which is connected to the main control module 1 and is used to obtain the angle information of the door leaf and transmit the angle information to the main control module 1.

[0073] Specifically, the angle sensor 21 senses the position of the door leaf, converts the position of the door leaf into an electrical signal, and transmits the electrical signal to the main control module 1. For example, it is preset that when the door leaf is in the closed state, the angle information of the door leaf is 0 degrees, and when the door leaf is in the fully open state, the angle information of the door leaf is 100 degrees. This is only an example and not limited thereto. During the opening or closing process of the door leaf, the angle information of the door leaf is detected in real time and transmitted to the main control module 1.

[0074] The door opener control system provided in this embodiment uses the angle sensor 21 to obtain the angle information of the door leaf and transmits the angle information to the main control module 1, which is convenient for accurately grasping the state of the door leaf and making corresponding controls accordingly, improving the intelligence level of the door opener control system.

[0075] In some alternative embodiments, as Figure 2 shown, the sensing module 2 further includes: a lidar 22 and a radar steering motor 23.

[0076] As Figure 2 shown, the radar steering motor 23 is connected to the lidar 22 and the main control module 1, and is used to drive the lidar 22 to rotate according to the angle information, so that the detection range of the lidar 22 is always a preset range.

[0077] It should be noted that the control of the radar steering motor can be any existing technology for controlling the motor to rotate a fixed number of turns or angles, and there is no limitation here.

[0078] As Figure 2 shown, the lidar 22 is connected to the main control module 1 and is used to detect whether there are people or objects within a preset range and transmit the detection result to the main control module 1.

[0079] Specifically, one radar steering motor 23 and one lidar 22 are a group, and a group of radar steering motor 23 and lidar 22 can be installed on the inner and outer sides of the door leaf respectively to detect whether there are people or objects within the preset ranges on the inner and outer sides of the door leaf respectively during the door opening and closing process. This is only an example and not limited thereto. The lidar 22 can also be replaced by an infrared sensor or a distance sensor. This is only an example here and not limited thereto.

[0080] The door opener control system provided in this embodiment uses the radar steering motor 23 to drive the lidar 22 to rotate, so that the detection range of the lidar 22 is always a preset range. The lidar 22 has a fast response speed, high accuracy, and strong anti-interference ability, ensuring the effectiveness and accuracy of the lidar 22 detection and improving the reliability of the door opener control system.

[0081] In some alternative embodiments, as Figure 2As shown in the figure, the door opener control system further includes: a camera 5, which is connected to the main control module 1 and is used to detect whether there are people or objects within a preset range and transmit the detection information to the main control module 1.

[0082] Specifically, the camera 5 can be installed on the door frame above the door leaf. Only by way of example, but not limited thereto, its detection range includes the preset range. The camera 5 is an AI intelligent anti-pinch camera 5, which can specifically identify people or objects and jointly detect whether there are people or objects within the preset range with the lidar 22, which can ensure more accurate detection results.

[0083] The door opener control system provided in this embodiment adds the detection of the camera 5 within the preset range, which can specifically identify people or objects, and the detection content is more comprehensive. By jointly detecting with the lidar 22, the obtained detection results are more accurate, and the safety of the door opener control system is higher.

[0084] In some alternative embodiments, as Figure 2 shown in the figure, the door opener control system further includes: a human-machine interaction interface 6, which is respectively connected to the main control module 1 and the camera 5 and is used to display the picture taken by the camera 5 and set the preset adjustable parameters of the door opener control system.

[0085] Specifically, the human-machine interaction interface 6 is connected to the camera 5 and is used to synchronously display the picture taken by the camera 5, so that the situation within the preset range can be intuitively grasped. At the same time, the human-machine interaction interface 6 is connected to the main control module 1, and the adjustable parameters can be set simply and conveniently. The process of setting the adjustable parameters can be to directly input numbers on the human-machine interaction interface to change the size of the adjustable parameters. Only by way of example, but not limited thereto, the adjustable parameters include but are not limited to the anti-pinch position within the preset range, the maximum opening angle of the door set according to the house type and the actual situation of the door opening, etc., making the door opener control system more flexible.

[0086] The door opener control system provided in this embodiment displays the picture taken by the camera 5 through the human-machine interaction interface 6, more intuitively shows the real situation within the preset range, and uses the human-machine interaction interface 6 to set the preset adjustable parameters, improving the use flexibility of the door opener control system.

[0087] In some alternative embodiments, as Figure 2 shown in the figure, the door opening motor module 3 includes: a door opening motor 31, a motor drive circuit 32, and a door opening motor current detection circuit 33.

[0088] As Figure 2 shown in the figure, the door opening motor 31 is connected to the door leaf and is used to open or close the door.

[0089] As Figure 2As shown, the motor drive circuit 32 is connected to the door-opening motor 31 and the main control module 1, and is used to drive the door-opening motor to operate according to the first instruction of the main control module 1.

[0090] As Figure 2 shown, the door-opening motor current detection circuit 33 is connected to the door-opening motor 31 and the main control module 1, and is used to detect the current of the door-opening motor 31. When the current of the door-opening motor 31 is greater than the preset current threshold, the door-opening motor 31 stops operating.

[0091] Specifically, the door-opening motor 31 is a DC brushless motor, and the motor drive circuit 32 is a DC brushless motor drive circuit 32. When the main control module 1 detects that the external door lock sends a door-opening signal and the lock tongue of the lock body is in place, the main control module 1 controls the motor drive circuit 32 to drive the door-opening motor 31 to perform a door-opening action. At the same time, the angle sensor 21 detects the door-opening angle in real time. When the door-opening angle reaches the set door-opening angle (for example, 100 degrees), the main control module 1 controls the door-opening motor 31 to stop operating.

[0092] After the door leaf is in place, after a preset time, the main control module 1 controls the motor drive circuit 32 to drive the door-opening motor 31 to reverse and start closing the door. During the door-closing process, the lidar 22 and the camera 5 detect the situation in the area where the door leaf moves (that is, the preset range, the area where there is a risk of pinching people or objects). When someone or an object enters the area where the door leaf moves, the main control module 1 stops closing the door according to the signals transmitted back by the lidar 22 and the camera 5, and controls the door-opening motor 31 to run forward to open the door, playing a role in anti-pinch protection.

[0093] It should be noted that the control of the door-opening motor module can be any control means for controlling the forward rotation, reverse rotation, and stop of the motor in the prior art. This is only an example here, but not limited thereto.

[0094] The door-opening motor current detection circuit 33 is used to detect the current of the door-opening motor 31. When the current is too large, there may be an obstacle preventing the movement of the door leaf, resulting in an excessive current of the door-opening motor 31. At this time, the signal of excessive current is sent to the main control module 1. After receiving the signal, the main control module 1 controls the motor drive circuit 32 to stop the door-opening motor 31 from operating, preventing the door-opening motor 31 from being overloaded and burned out.

[0095] The door-opening machine control system provided in this embodiment enables the door-opening motor module 3 to automatically open and close the door, saving manpower. At the same time, it detects the current of the door-opening motor 31, avoids burning out the motor due to excessive current, and increases the service life of the door-opening motor 31.

[0096] In some alternative embodiments, the door-opening motor is a three-phase motor, such as Figure 3As shown in the figure, the motor drive circuit 32 includes: six transient voltage suppression diodes. Among them, for the first transient voltage suppression diode, its first end is connected to the first phase of the three-phase motor, and its second end is connected to the second phase of the three-phase motor; for the second transient voltage suppression diode, its first end is connected to the first phase of the three-phase motor, and its second end is connected to the third phase of the three-phase motor; for the third transient voltage suppression diode, its first end is connected to the third phase of the three-phase motor, and its second end is connected to the second phase of the three-phase motor; for the fourth transient voltage suppression diode, its first end is connected to the first phase of the three-phase motor, and its second end is grounded; for the fifth transient voltage suppression diode, its first end is connected to the second phase of the three-phase motor, and its second end is grounded; for the sixth transient voltage suppression diode, its first end is connected to the third phase of the three-phase motor, and its second end is grounded.

[0097] Specifically, Figure 3 Among them, D10, D4, D15, D6, D9, and D11 are six transient voltage suppression diodes. The three pins of the terminal block JP8 are respectively connected to the three phases of the three-phase motor. The three terminal blocks A, B, and C are respectively connected to three motor drive chips and then connected to the main control module. The model of the motor drive chip and its peripheral circuit can be a solution that can drive the motor in the prior art, which will not be elaborated here.

[0098] For the door opener control system provided in this embodiment, the three-phase motor has the characteristics of energy saving and stability. Selecting a three-phase motor for the door opening motor is beneficial to improving the stability of the door opener control system and saving energy at the same time. Transient voltage suppression diodes are connected between two phases of the three-phase motor to prevent the back electromotive force generated during the start and stop of the door opening motor from breaking down and burning the internal electronic devices of the control system such as the motor drive circuit 32 and the control circuit.

[0099] In some optional implementation manners, as Figure 2 shown, the clutch module 4 includes: a clutch 41, a clutch motor 42, and a clutch current detection circuit 43.

[0100] As Figure 2 shown, the clutch 41 is used to separate or close with the door opening motor module 3.

[0101] As Figure 2 shown, the clutch motor 42 is connected to the main control module 1 and the clutch 41, and is used to control the separation and engagement degree of the clutch 41 and the door opening motor module 3 according to the second instruction of the main control module 1.

[0102] As Figure 2 shown, the clutch current detection circuit 43 is connected to the main control module 1 and the clutch, and is used to detect the current of the clutch 41 and judge the separation and engagement degree of the clutch 41 and the door opening motor.

[0103] Specifically, the clutch 41 is similar to the clutch structure used in automobiles. The force exerted by the door opening motor on the door leaf during the opening and closing process is controlled by the degree of engagement between the friction plate and the door opening motor. When in normal use, the clutch 41 is engaged, and the door opening motor drives the corresponding mechanism to open the door; when power is off, the clutch 41 disengages, and the door can be manually pushed or pulled to open or close. The clutch current detection circuit 43 is used to detect the current of the clutch motor 42 and determine the closing degree of the clutch 41 based on the current of the clutch motor 42. The greater the current of the clutch motor 42, the tighter the clutch 41 closes, and the greater the force required for manual opening and closing of the door. When power is off, the current of the clutch motor 42 is 0, that is, the clutch 41 is completely disengaged, and the force required for manual opening and closing of the door is the smallest, which is more user-friendly for the elderly and children.

[0104] It should be noted that the working principle of the clutch module is the same as that of the existing automobile clutch, and will not be elaborated here.

[0105] In the door opener control system provided in this embodiment, the clutch motor 42 drives the clutch to separate or engage with the door opening motor module 3, reducing the resistance of opening and closing the door and improving the intelligence level of the door opener control system.
