Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to an intelligent roller shutter based on LED strip indicator. Background Technology

[0002] In logistics and production workshops, PVC high-speed rolling doors are key equipment for space isolation and security. Current technology uses limited lighting strips on these doors, providing only basic status indication and lacking dynamic warning and boundary marking capabilities.

[0003] Firstly, most roller shutter door light strips only use a single color to indicate the status, making it impossible to distinguish the operating status through color coding, which makes it difficult for drivers to identify the status of the doorway from a distance.

[0004] Secondly, the light strips are only partially installed at the top of the door frame, failing to continuously illuminate and outline the three-dimensional contours of the doorway. This can easily lead to collisions due to blind spots when forklifts are reversing (industrial accident statistics show that collisions related to roller shutter doors account for 18% of logistics accidents). Furthermore, the existing technology does not integrate with a vehicle navigation system, making it impossible to predict risks before the door closes, resulting in high delays in dynamic warnings.

[0005] Third, existing technologies do not link the door status with the surrounding environment perception system, which cannot meet the security requirements of high-density logistics scenarios. Utility Model Content

[0006] Therefore, this utility model provides an intelligent roller shutter door based on LED strip indicator to overcome the problem of the single indicator status of LED strip indicator in existing roller shutter doors.

[0007] To achieve the above objectives, this utility model provides an intelligent roller shutter door based on LED strip indicator, comprising:

[0008] Door body;

[0009] A lintel, which is located at the top of the door body, and has a drive motor installed inside it;

[0010] The door curtain is connected to the power output end of the drive motor;

[0011] The guide rail assembly is disposed inside the two sides of the door body, including a protective cover vertically disposed on both sides of the door body, and a guide groove disposed inside the guide rail for the door curtain to slide.

[0012] An indicator comprising a light strip that surrounds the inner guide groove edge of the guide rail and the bottom of the lintel, and a color-changing controller connected to the light strip to control the color of the light strip when it is turned on;

[0013] The data acquisition module is used to acquire biological activity signals in front of the door and information on the opening status of the door curtain;

[0014] The controller, which is connected to both the data acquisition module and the color-changing controller, is used to determine the operation of the indicator based on the information acquired by the data acquisition module.

[0015] Furthermore, in response to the absence of biological activity signals in front of the door and the door curtain being closed, the controller controls the light strip to turn on in a constant blue light.

[0016] The controller responds to the absence of biological activity signals in front of the door and the door curtain being open by controlling the light strip to turn on in a constant green light.

[0017] The controller responds to the absence of biological activity signals in front of the door and the door curtain being in operation by controlling the light strip to turn on in a constant yellow light.

[0018] The controller responds to a biological activity signal in front of the door and the door curtain being open or in operation by controlling the light strip to turn on in a constant red light.

[0019] Furthermore, in response to the absence of biological activity signals in front of the door and the termination of the operation of the door curtain, the controller controls the light strip to turn on with a yellow flashing light for a duration of 2 seconds and a frequency of 2Hz.

[0020] Furthermore, the controller is an STM32F7 series microcontroller.

[0021] Furthermore, the curtain is made of PVC coated fabric with a thickness of 0.8 to 1.3 mm.

[0022] Furthermore, the guide rail is made of extruded aluminum alloy profile.

[0023] Furthermore, the light strip is a waterproof COB-packaged LED light strip.

[0024] Compared with the prior art, the advantages of this utility model are as follows: By setting up a light strip arranged around the edge of the guide groove on the inner side of the guide rail and the bottom of the lintel, and in conjunction with a color-changing controller, a data acquisition module and a controller, this utility model realizes intelligent linkage light strip indication based on the working status of the door curtain and the biological activity signals in front of the door, effectively solving the problem of the single status of the light strip indication of the roller shutter door in the prior art.

[0025] Furthermore, the controller can control the light strip to display different colors such as blue, green, yellow, or red based on the door curtain's closing, opening, and operating status obtained by the data acquisition module, as well as whether there are biological activity signals in front of the door. This provides clear and accurate feedback on the current working status of the roller shutter door and the surrounding environment, improving the intuitiveness of the indication and the efficiency of information transmission.

[0026] Furthermore, when there is a biological activity signal in front of the door and the door curtain is open or running, the light strip displays a solid red light, which can promptly remind users or passersby to pay attention to safety and avoid collisions or pinching accidents, thus enhancing safety during use. When the door curtain stops running, the controller controls the light strip to flash yellow for 2 seconds at a frequency of 2Hz, further enhancing the indication effect of the status switch, making it easy for users to know in time that the door curtain has stopped running, and improving the convenience of use.

[0027] Furthermore, the curtain is made of PVC coated fabric with a thickness of 0.8 to 1.3 mm, which takes into account durability, flexibility and anti-aging performance; the guide rail is made of aluminum alloy extruded profile, which is sturdy and not easily deformed, ensuring the stability of the curtain sliding; the light strip is a waterproof COB encapsulated LED light strip, which has good waterproof performance, is suitable for outdoor or humid environments, and extends its service life.
