Abstract

The application discloses a protective door monitoring control system and a protective door adopting the same. The system realizes automatic control of opening and closing of the protective door through a door leaf driving motor and a locking driving motor. The opening and closing angle of the door leaf can be detected through a pull rope sensor during opening and closing of the protective door, so that the opening and closing state of the protective door is automatically monitored. Moreover, the opening and closing speed of the door leaf is controlled according to the opening and closing angle value detected by the pull rope sensor during opening and closing of the protective door, so that the door leaf is stably opened and closed. Meanwhile, the support device is controlled to extend and effectively support the far end of the door leaf when the pull rope sensor detects that the opening angle of the door leaf reaches the maximum angle, so that the creep sinking deformation of the far end is greatly relieved. In addition, ultrasonic monitoring and infrared monitoring are combined, so that obstacles and passing personnel can be intelligently detected. Through integration of various intelligent monitoring means, the intelligent dynamic monitoring and intelligent control functions of the protective door are realized.

Description

Technical Field

[0001] This invention relates to the field of security door technology, and in particular to a security door monitoring and control system, and also to a security door using the above system. Background Technology

[0002] In national defense and civil defense projects, protective doors are required at entrances and exits connecting buildings and facilities to the outside to ensure overall safety during wartime. Arched protective doors are often installed at the entrances of civil defense projects requiring high resistance levels to withstand the intrusion of blast shock waves during wartime, preventing severe vibrations inside the buildings and facilities that could cause casualties, equipment failure, or command system malfunctions. To enhance the impact resistance of these protective doors, current common methods include increasing the thickness of the door's molding plate or adding structural reinforcing ribs inside the door. This increases the door's weight, making opening and closing time-consuming and labor-intensive. Furthermore, due to the increased weight, the far end of the door is prone to creep and subsidence deformation after opening, potentially causing it to fail to open and close properly, leading to protective failure. The deformation caused by creep and subsidence is often a slow, cumulative process over a long period, and the failure to open and close is also random. Therefore, reliable monitoring of the door's opening and closing process is essential. In addition, if people fail to pass through in time during the opening and closing of the door, they may be injured by the door. Therefore, it is necessary to effectively protect the personal safety of people passing through, and also to detect whether there are any obstacles within the opening and closing range of the door. Summary of the Invention

[0003] This invention provides a protective door monitoring and control system and a protective door using the same, so as to monitor the status of the protective door during the opening and closing process in real time.

[0004] According to one aspect of the present invention, a security door monitoring and control system is provided. The security door includes a door frame, a door leaf, and a locking mechanism. The door frame is embedded in a wall, the door leaf is connected to the door frame via a hinge mechanism, and the locking mechanism is installed in the door frame for locking or unlocking the door leaf. The security door monitoring and control system comprises:

[0005] Door drive motor, used to drive the door to open and close;

[0006] A locking drive motor is used to drive the locking mechanism to perform locking or unlocking actions.

[0007] A support device is used to support the far end of the door after the door is opened to the correct position.

[0008] A pull cord sensor is used to detect the opening and closing angle of the door.

[0009] The controller is electrically connected to the door leaf drive motor, the locking drive motor, the support device, and the pull rope sensor. Upon receiving an opening control command, it first controls the locking drive motor to unlock the locking mechanism, then controls the door leaf drive motor to open the door. During the opening process, it controls the speed of the door leaf drive motor based on the angle value detected in real-time by the pull rope sensor to control the opening speed of the door. When the pull rope sensor detects that the opening angle of the door leaf has reached its maximum, it controls the support device to extend to support the far end of the door leaf. Upon receiving a closing control command, it first controls the support device to retract, then controls the door leaf drive motor to close the door. During the closing process, it controls the speed of the door leaf drive motor based on the angle value detected in real-time by the pull rope sensor to control the closing speed of the door leaf. After the stall time of the door leaf drive motor reaches a preset time, it controls the locking drive motor to lock the locking mechanism.

[0010] Furthermore, it also includes an ultrasonic sensor electrically connected to the controller for detecting whether there are obstacles in the door opening and closing area. The controller is also used to control the door drive motor to stop working when the ultrasonic sensor detects that there are obstacles in the door opening and closing area.

[0011] Furthermore, it also includes an infrared detection sensor electrically connected to the controller for detecting whether someone is passing through the door opening and closing area. The controller is also used to control the door drive motor to stop working when the infrared detection sensor detects that someone is passing through the door opening and closing area.

[0012] Furthermore, it also includes a limit switch electrically connected to the controller for detecting whether the locking mechanism has been activated. The controller is also used to control the locking drive motor to continue driving the locking mechanism to perform the locking action when the limit switch does not detect that the locking mechanism has been activated.

[0013] Furthermore, it also includes a display screen electrically connected to the controller for displaying status monitoring data and facilitating human-machine interaction.

[0014] Furthermore, it also includes an operation box installed outside the door, which is equipped with a call button, an open button, and a close button. A doorbell is installed inside the door or at a remote center. The operation box is communicatively connected to the doorbell and electrically connected to the controller. When a person enters the door, they press the call button on the operation box, and the doorbell rings. The administrator then grants the operation box the authority to open and close the door through the controller. Only then can the person enter the door control the door opening and closing using the open and close buttons on the operation box.

[0015] Furthermore, the support device includes a support mechanism and a support motor. The support motor is electrically connected to the controller and is used to drive the support mechanism to extend or retract. When the controller detects that the torque of the support motor reaches a preset threshold through current detection, it determines that the support mechanism has extended or retracted into place, and then controls the support motor to stop working.

[0016] Furthermore, the ultrasonic sensors are multiple and are evenly spaced above the door frame.

[0017] Furthermore, the display screen includes a main interface, a parameter setting interface, and an alarm interface. The main interface is used to display status monitoring data, the parameter setting interface is used to set control parameters, and the alarm interface is used to display alarm information.

[0018] In addition, the present invention also provides a protective door, which employs the protective door monitoring and control system described above.

[0019] The present invention has the following effects:

[0020] The protective door monitoring and control system of this invention achieves automated control of the opening and closing of the protective door through the door leaf drive motor and the locking drive motor. During the opening and closing process, a pull rope sensor detects the opening and closing angle of the door leaf, thereby automatically monitoring the opening and closing status of the protective door and quickly identifying potential opening and closing failures during operation. Furthermore, the opening and closing speed of the door leaf is controlled based on the opening and closing angle value detected by the pull rope sensor, ensuring smooth opening and closing. Simultaneously, when the pull rope sensor detects that the door leaf has reached its maximum opening angle, indicating that the door leaf is fully open, the support device is extended to effectively support the far end of the door leaf, greatly mitigating creep and sinking deformation at the far end.

[0021] In addition, ultrasonic sensors are installed to detect whether there are obstacles in the door opening and closing area. When an obstacle is detected, the protective door is controlled to stop moving, which further improves the safety of the opening and closing of the protective door and realizes intelligent dynamic monitoring and intelligent control of the protective door.

[0022] In addition, an infrared detection sensor is installed to intelligently detect people passing through, realizing an anti-pinch function design, ensuring the safety of people passing through, and realizing intelligent dynamic monitoring and intelligent control of the protective door.

[0023] In addition, the protective door of the present invention also has the above-mentioned advantages.

[0024] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the figures. Attached Figure Description

[0032] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0033] Understandable, such as Figure 1 and Figure 2As shown, a preferred embodiment of the present invention provides a protective door monitoring and control system. The protective door includes a door frame 7, a door leaf 4, and a locking mechanism 3. The door frame 7 is embedded in the wall, and the door leaf 4 is connected to the door frame 7 via a hinge mechanism 6. The locking mechanism 3 is installed in the door frame 7 and is used to lock or unlock the door leaf 4. The locking mechanism 3 can be a pin-type structure, with a pin hole on the door leaf 4. Locking is achieved when the pin is inserted into the pin hole, and unlocking is achieved when the pin is pulled out of the pin hole. Of course, in other embodiments of the present invention, the locking mechanism 3 can also adopt other locking structures. The protective door monitoring and control system includes a door leaf drive motor 1, a locking drive motor 2, a support device 5, a pull rope sensor, and a controller. The door leaf drive motor 1 is driven by the door leaf 4 and is used to drive the door leaf 4 to perform opening and closing actions. The locking drive motor 2 is driven by the locking mechanism 3 and is used to drive the locking mechanism 3 to perform locking or unlocking actions. The door leaf drive motor 1 and the locking drive motor 2 are specifically installed in the door frame 7. The support device 5 is installed on the outside of the protective door to support the far end of the door leaf 4 after it is opened to the correct position. The pull rope sensor is installed on the door leaf 4 to detect the opening and closing angle of the door leaf 4. The controller is electrically connected to the door leaf drive motor 1, the locking drive motor 2, the support device 5, and the pull rope sensor. After receiving the door opening control command, the controller first controls the locking drive motor 2 to drive the locking mechanism 3 to perform the unlocking action, and then controls the door leaf drive motor 1 to drive the door leaf 4 to open. During the opening of the door leaf 4, the controller controls the action speed of the door leaf drive motor 1 according to the angle value detected by the pull rope sensor in real time to control the opening speed of the door leaf 4. For example, during the opening of the door leaf 4, when the pull rope sensor detects that the opening angle of the door leaf 4 reaches the angle value corresponding to the preset deceleration position, the controller controls the door leaf drive motor 1 to decelerate to ensure that the door leaf 4 can stop in time after rotating to the stop position. When the pull rope sensor detects that the angle of the door leaf 4 reaches the maximum angle (i.e., the door leaf 4 is opened to the correct position), the controller controls the support device 5 to extend to support the far end of the door leaf 4. Upon receiving the door closing control command, the controller first retracts the support device 5, then controls the door drive motor 1 to close the door 4. During the closing process, the controller adjusts the speed of the door drive motor 1 based on the angle value detected in real time by the pull rope sensor to control the closing speed of the door 4. For example, when the pull rope sensor detects that the angle of the door 4 reaches the angle value corresponding to the preset deceleration position, the controller controls the door drive motor 1 to decelerate to ensure that the door 4 can stop in time after rotating to the stop position. After the stall time of the door drive motor 1 reaches the preset time (e.g., 5 seconds), it means that the door 4 is closed in place, and the controller controls the locking drive motor 2 to drive the locking mechanism 3 to perform the locking action. Preferably, the door drive motor 1 and the locking drive motor 2 are torque motors.

[0034] It is understood that the protective door monitoring and control system of the present invention achieves automated control of the opening and closing of the protective door through the door leaf drive motor 1 and the locking drive motor 2. During the opening and closing process of the protective door, the opening and closing angle of the door leaf 4 can be detected by the pull rope sensor, thereby automatically monitoring the opening and closing status of the protective door and quickly identifying potential opening and closing failures during the operation of the protective door. Furthermore, during the opening and closing process of the protective door, the opening and closing speed of the door leaf 4 is controlled according to the opening angle value detected by the pull rope sensor to ensure smooth opening and closing of the door leaf 4. At the same time, when the pull rope sensor detects that the opening angle of the door leaf 4 has reached the maximum angle, it means that the door leaf 4 is fully opened, and the support device 5 is extended to effectively support the far end of the door leaf 4, greatly alleviating the creep and sinking deformation of the far end.

[0035] Optionally, the protective door monitoring and control system also includes a limit switch electrically connected to the controller for detecting whether the locking mechanism 3 has been properly engaged. The controller further controls the locking drive motor 2 to continue driving the locking mechanism 3 to perform the locking action when the limit switch fails to detect the locking mechanism 3's engagement, ensuring that the locking mechanism 3 is properly engaged and the door leaf 4 is locked. Additionally, if the limit switch still fails to detect the locking mechanism 3's engagement after multiple feedback controls, the controller issues an alarm to remind personnel to perform timely maintenance.

[0036] Optionally, the security door monitoring and control system further includes an ultrasonic sensor electrically connected to the controller for detecting whether there are obstacles in the door opening and closing area. The controller is also used to control the door drive motor 1 to stop working when the ultrasonic sensor detects an obstacle in the door opening and closing area, ensuring the safety of the door 4 opening and closing process. Wherein, as Figure 3 As shown, there are multiple ultrasonic sensors, evenly spaced above the door frame 7. For a protective door with a width of 2m and a height of 2.4m, four ultrasonic sensors are evenly spaced, each covering a detection diameter of 0.5m, thus completely covering obstacle detection within the door width. In other embodiments of the invention, the number of ultrasonic sensors and the coverage area of ​​a single sensor can be set according to actual needs, and are not specifically limited here.

[0037] In addition, the security door monitoring and control system also includes an infrared detection sensor electrically connected to the controller for detecting whether anyone is passing through the door opening and closing area. The controller is also used to control the door drive motor 1 to stop working when the infrared detection sensor detects that someone is passing through the door opening and closing area. Specifically, as Figure 4As shown, the infrared detection sensor is installed above the passageway, 2m away from the protective door. Its detection range completely covers the opening and closing area of ​​the protective door. When the infrared detection sensor detects someone passing by, it controls the protective door to stop opening and closing to prevent injury.

[0038] Optionally, the security door monitoring and control system also includes an operation box located outside the door. The operation box is equipped with a call button, an open button, and a close button. A doorbell is installed inside the door or at a remote center. The operation box is communicatively connected to the doorbell and electrically connected to the controller. When a person entering the door presses the call button on the operation box, the doorbell inside the door or at the remote center rings. The administrator then grants the operation box opening and closing permissions via the controller. Only then can the person entering control the door opening and closing using the open and close buttons on the operation box, thus achieving access control for the security door.

[0039] The supporting device 5 specifically includes a supporting mechanism and a supporting motor. The supporting motor is electrically connected to the controller and is used to drive the supporting mechanism to extend or retract. When the controller detects that the torque of the supporting motor reaches a preset threshold through current detection, it determines that the supporting mechanism has extended or retracted to its proper position and then controls the supporting motor to stop working. Furthermore, the supporting device 5 only extends or retracts when the door 4 is fully open; it is not allowed to operate during the opening or closing of the protective door. Preferably, the supporting motor is a servo motor.

[0040] In addition, the protective door monitoring and control system also includes a display screen electrically connected to the controller for displaying status monitoring data and facilitating human-machine interaction. The display screen allows for monitoring of the protective door's status and control of its operating parameters. The display screen includes a main interface, a parameter setting interface, and an alarm interface. The main interface displays status monitoring data, the parameter setting interface sets control parameters, and the alarm interface displays alarm information. For example, the upper left of the main interface displays the angle detection data of the pull rope sensor, the lower left contains buttons for setting the operator's local and remote operation permissions for door leaf 4, and the right half displays the working status of the door leaf drive motor 1, the locking drive motor 2, and the support motor. The left side of the parameter setting interface has five parameter setting input boxes: door leaf motor speed setting, locking motor speed setting, support motor speed setting, door leaf opening angle setting, and door leaf closing angle setting. The right side has two function buttons: a reset button and a factory reset button. The alarm interface displays alarm information in a list format, with the list header sequentially set as: number-time-date-operating status code-alarm text corresponding to the operating abnormality code. The display screen is preferably an HMI display screen, which has display and touch functions.

[0041] In addition, another embodiment of the present invention provides a protective door, preferably employing the protective door monitoring and control system described above.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
