Description

Technical Field

[0001] This utility model relates to the field of automatic door technology, and more specifically, to an automatic door with voice alarm reminder function and fault feedback function. Background Technology

[0002] With the rapid development of intelligent buildings and automation technologies, automatic door systems are increasingly being used in public places such as shopping malls, hospitals, and office buildings. Traditional automatic doors mainly use infrared sensors or microwave radar to detect the movement of people or objects, thereby opening and closing the door. However, such systems still have significant shortcomings in fault detection, security assurance, and remote maintenance.

[0003] Existing automatic doors typically rely on motor encoders or limit switches to detect their operating status, but these methods cannot accurately identify problems such as abnormal door shaking, jamming, or imbalance. They are also prone to missed faults due to mechanical wear or sudden external interference. Ordinary sensors detect objects caught only based on instantaneous resistance feedback, resulting in a high false alarm rate. If the door suddenly accelerates or becomes uncontrollable due to a malfunction, existing systems struggle to brake in time, posing a risk of injuring pedestrians or damaging equipment. Traditional automatic doors lack real-time data recording and remote diagnostic capabilities, requiring on-site repairs for troubleshooting, which is inefficient and fails to meet the demands of modern intelligent operation and maintenance. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic door with voice alarm reminder function and fault feedback function, so as to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0006] An automatic door with voice alarm and fault feedback functions includes an automatic door frame and a control box installed on its inner wall. The control box contains a door drive device. Two fixed door leaves and two movable door leaves are installed on the inner wall of the automatic door frame. The two movable door leaves are located on opposite sides of the two fixed door leaves. The top of the movable door leaves is connected to the door drive device. A monitoring structure is fixedly installed on the front of each of the two movable door leaves.

[0007] The control box integrates a processor, a communication module, and a fault generation module. The communication module, door drive device, and fault generation module are all connected to the processor via signals. The door drive device transmits motor speed, current, and encoder position signals to the processor in real time. The fault generation module receives sensor data packets sent by the processor and returns status data containing fault codes. The communication module receives the status data sent by the processor and uploads it to the cloud platform via the network.

[0008] The monitoring structure includes a mounting base installed on the front of the movable door leaf. A support shaft is fixedly installed on the inner wall of the mounting base. A gravity block is provided inside the mounting base, and a limit groove is formed inside the gravity block. The inner wall of the limit groove fits against the support shaft. A pressure sensor is fixedly installed on the inner bottom wall of the mounting base. A pressure plate is attached to the top of the pressure sensor. A spring is fixedly installed on the top of the pressure plate. A retaining plate is connected to the top of the spring. The top of the retaining plate contacts the gravity block. The pressure sensor is signal-connected to a processor. The pressure sensor is used to acquire the pressure value generated by the pressure plate and transmit it to the processor. The processor compares the acquired pressure value with a set threshold to determine whether there is an abnormality in the automatic door, thereby controlling the operation of the communication module.

[0009] As a further description of the above technical solution: a cover plate is bolted to the front of the mounting base, and the cover plate covers the front of the mounting base.

[0010] As a further description of the above technical solution: two limiting posts are connected to the inner wall of the mounting base, and the two limiting posts are respectively located on the left and right sides of the card plate.

[0011] As a further description of the above technical solution: a buzzer is fixedly installed at the bottom of the automatic door frame, and the buzzer is connected to the processor via a signal.

[0012] As a further description of the above technical solution: an infrared ray sensor is fixedly installed on the gravity block on the left, and an infrared signal receiver is fixedly installed on the gravity block on the right. The infrared ray sensor and the infrared signal receiver are configured correspondingly. The infrared signal receiver is connected to the processor. After receiving the infrared signal, the infrared signal receiver transmits it to the processor.

[0013] As a further description of the above technical solution: each of the two mounting bases has a through groove on its opposite side, the through groove being used to pass infrared ray signals.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] In this invention, under normal operating conditions, the door drive device runs smoothly, and sensor data is uploaded to the processor and cloud platform in real time to ensure worry-free remote monitoring. If the door experiences abnormal acceleration, sudden stop, clamping of objects, or mechanical imbalance, the inertia of the gravity block will trigger an over-threshold alarm from the pressure sensor. At the same time, the infrared beam signal is interrupted due to the door's offset. Dual signal verification significantly improves the accuracy of fault diagnosis. The processor responds immediately, linking the buzzer to play a directional voice alarm and urgently braking the door to avoid personal injury. All fault codes are pushed to the cloud in real time through the communication module, supporting maintenance personnel to quickly locate problems. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] To improve the safety performance of automatic doors and facilitate timely detection of malfunctions, this solution provides Implementation Example 1:

[0023] Please see Figures 1-3 In this utility model, an automatic door with voice alarm and fault feedback functions includes an automatic door frame 1 and a control box 2 installed on its inner wall. The control box 2 is equipped with a door drive device 3. Two fixed door leaves 4 and two movable door leaves 5 are installed on the inner wall of the automatic door frame 1. The two movable door leaves 5 are located on the opposite side of the two fixed door leaves 4. The top of the movable door leaves 5 is connected to the door drive device 3. A monitoring structure 6 is fixedly installed on the front of each of the two movable door leaves 5. A buzzer 12 is fixedly installed at the bottom of the automatic door frame 1. The buzzer 12 is connected to the processor 7.

[0024] The control box 2 integrates a processor 7, a communication module 8, and a fault generation module 9. The communication module 8, the door drive device 3, and the fault generation module 9 are all connected to the processor 7. The door drive device 3 transmits motor speed, current, and encoder position signals to the processor 7 in real time. The fault generation module 9 receives the sensor data packets sent by the processor 7 and returns status data containing fault codes. The communication module 8 receives the status data sent by the processor 7 and uploads it to the cloud platform via the network.

[0025] The monitoring structure 6 includes a mounting base 601, which is installed on the front of the movable door leaf 5. A support shaft 602 is fixedly installed on the inner wall of the mounting base 601. A gravity block 603 is provided inside the mounting base 601, and a limit groove 604 is formed inside the gravity block 603. The inner wall of the limit groove 604 fits against the support shaft 602. A pressure sensor 605 is fixedly installed on the inner bottom wall of the mounting base 601. A pressure plate 606 is attached to the top of the pressure sensor 605, and a spring is fixedly installed on the top of the pressure plate 606. 607, the top of the spring 607 is connected to the clamping plate 608, and two limiting posts 11 are connected to the inner wall of the mounting base 601. The two limiting posts 11 are located on the left and right sides of the clamping plate 608 respectively. The top of the clamping plate 608 is in contact with the gravity block 603. The pressure sensor 605 is connected to the processor 7. The pressure sensor 605 is used to obtain the pressure value generated by the pressure plate and transmit it to the processor 7. The processor 7 determines whether there is an abnormality in the automatic door by comparing the obtained pressure value with the set threshold, thereby controlling the operation of the communication module 8.

[0026] In this utility model, when the automatic door is running normally, the door drive device 3 controls the two movable door panels 5 to open and close smoothly along the track. The motor speed, current and encoder position signals are fed back to the processor 7 in real time. The gravity block 603 in the monitoring structure 6 remains stable under the constraint of the support shaft 602 and the limiting groove 604, and is only subject to gravity. The pressure value detected by the pressure sensor 605 is a constant reference value.

[0027] The fault generation module 9 continuously monitors sensor data. If there is no abnormality, the communication module 8 only uploads the operating status to the cloud platform, and the buzzer 12 does not trigger an alarm.

[0028] Abnormal situations are detected, such as sudden acceleration, sudden stop, or being caught in an obstacle, abnormal vibration, or impact. If the movable door 5 suddenly accelerates, intermittently shakes, or suddenly stops due to mechanical failure or external interference, the inertia will cause the gravity block 603 to sway on the support shaft 602, which in turn will press the card plate 608 to move down, compress the spring 607, and cause the pressure plate 606 to exceed the set threshold pressure value of the pressure sensor 605.

[0029] If the door gets caught on an object such as a pedestrian or item, the resistance of the movable door 5 increases, the current of the drive motor rises abnormally, and the gravity block 603 swings more violently due to the obstruction, causing the pressure sensor 605 to display abnormal data.

[0030] The processor 7 compares the data from the pressure sensor 605 with the threshold to determine the fault type, such as "overload" or "blockage". It immediately plays a voice alarm, such as "Door abnormality, do not approach", through the buzzer 12. At the same time, it instructs the door drive device 3 to brake urgently and pushes the fault code to the cloud platform through the communication module 8.

[0031] Please see Figure 1The front of the mounting base 601 is bolted to a cover plate 10, which covers the front of the mounting base 601.

[0032] In this utility model, the cover plate 10 connected by bolts can be quickly disassembled and assembled, thereby exposing the interior of the mounting base 601, which is convenient for internal inspection and replacement.

[0033] Based on the above embodiment one, in order to further improve the monitoring accuracy and ensure the stable operation of the automatic door, this solution provides embodiment two:

[0034] Please see Figures 1-3 In this configuration, an infrared ray sensor 13 is fixedly installed on the gravity block 603 on the left, and an infrared signal receiver 14 is fixedly installed on the gravity block 603 on the right. The infrared ray sensor 13 and the infrared signal receiver 14 are set accordingly. The infrared signal receiver 14 is connected to the processor 7 and transmits the infrared signal to the processor 7 after receiving the infrared signal. A through slot 15 is opened on the opposite side of the two mounting bases 601. The through slot 15 is used to pass infrared ray signals.

[0035] In this utility model, an infrared ray sensor 13 is installed on the left gravity block 603, and an infrared signal receiver 14 is installed on the right side. The two are aligned through a through slot 15. Under normal conditions, infrared rays are continuously captured by the infrared signal receiver 14, and the processor 7 receives a stable signal to determine that the door is running smoothly.

[0036] If the movable door 5 causes the gravity block 603 to swing due to vibration, tilting, or uneven speed, the relative position of the infrared ray and the receiver will shift, and the signal will be interrupted or fluctuate. The processor 7 combines the data from the pressure sensor 605 and the number of times the infrared signal is lost to comprehensively judge the fault and further improve the judgment accuracy.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
