Description

Technical Field

[0001] This invention relates to the field of management system technology, specifically to a smart management system for industrial parks based on 5G technology. Background Technology

[0002] With the development of mobile communication technology, human beings have become more efficient in exchanging information. However, the integration of the internet with the real economy requires expanding into more business scenarios, creating a larger connection scale, and richer application scenarios. 4G technology cannot meet the demands of social development for mobile communication technology. There is an urgent need for a new generation of communication technology that can better adapt to complex scenarios and has better transmission performance to meet the needs of industrial development and people's production and life. 5G is the main direction of the development of the next generation of mobile communication technology and an important component of the future next-generation information infrastructure. Compared with 4G, 5G has the technical characteristics of "ultra-high speed, ultra-low latency, and ultra-large connection". It will not only further improve the user's network experience and bring faster transmission speeds to mobile terminals, but also meet the application needs of the future Internet of Things, giving everything the ability to connect online. In addition, 5G can also promote the application of artificial intelligence products. Currently, artificial intelligence is an innovation hotspot in the entire technology field. Big data, cloud computing, the Internet of Things, and many other technologies ultimately point to artificial intelligence. 5G has a very positive significance for the research and development and application of artificial intelligence products. Through 5G, the application scenarios of artificial intelligence products can be further improved. 5G can also be applied to industrial parks, making smart parks more intelligent than traditional industrial parks. When using existing 5G networks, industrial enclosures are needed to protect 5G technology smart management equipment to avoid damage to the electrical system.

[0003] Existing technology, such as the patent with publication number CN215774079U, discloses a 5G equipment industrial chassis. This chassis includes an outer shell and a heat dissipation column. The outer shell has a cavity for mounting working components and a heat dissipation vent connecting to the cavity. The vent has internal threads. The heat dissipation column is hollow and connected to the cavity. Its circumferential side has external threads and heat dissipation holes. The heat dissipation column is threaded into the heat dissipation vent. Normally, the heat dissipation column closes the heat dissipation vent, and the heat dissipation holes are blocked by the inner wall of the vent, sealing the cavity and effectively preventing dust. During use, the heat dissipation column is rotated and extended outwards, exposing the heat dissipation holes on its surface. These holes communicate with the interior of the cavity, allowing heat to dissipate from the cavity.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] In the aforementioned prior art, the 5G equipment industrial chassis uses a drive motor to move the heat dissipation column outside the casing for cooling by a fan. When cooling is not needed, the heat dissipation column moves inside the casing for dust protection. However, in actual use, the drive motor is expensive to manufacture, and the outer end of the heat dissipation column is flat. When the fan blows air into the heat dissipation column to cool the inside of the casing, the outer end of the heat dissipation column will block the exhaust heat to a certain extent, affecting the exhaust flow rate of heat and resulting in poor heat dissipation inside the casing. Therefore, a smart management system for industrial parks based on 5G technology is proposed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a smart management system for industrial parks based on 5G technology, which improves the heat dissipation effect of industrial chassis for 5G smart management equipment at a low cost.

[0009] Preferably, the return force blocking assembly further includes a rotating rod, with both ends of the rotating rod passing through two rotating holes respectively.

[0010] Preferably, the rebound shielding assembly further includes a limiting plate, which is fixedly connected to the top wall inside the heat dissipation vent of the upper chassis, and the limiting plate blocks and restricts the shielding plate.

[0011] Preferably, the return shield assembly further includes a bottom filter plate and two side filter plates, one side of the side filter plate and one end of the bottom filter plate are fixedly connected to the inner wall of the shield plate, and the other side of the side filter plate is fixedly connected to the upper surface of the bottom filter plate.

[0012] Preferably, the end of the bottom filter plate away from the baffle plate has an inclined structure, and this end of the bottom filter plate abuts against the bottom surface of the heat dissipation vent on the lower chassis.

[0014] Preferably, mounting slots are provided on both sides of the fan, and the first and second clips are fitted into the mounting slots.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-11 The industrial park smart management system based on 5G technology in this embodiment includes an upper chassis 1 and a lower chassis 2. The lower chassis 2 is equipped with a communication module 5, a remote control and monitoring module 6, an edge computing / edge AI module 7, a security and privacy protection module 8, and an intelligent automation module 9. The side walls of the upper chassis 1 and the lower chassis 2 are provided with multiple corresponding heat dissipation vents 10. The inner walls of the upper chassis 1 and the lower chassis 2 are respectively fixedly connected with multiple first clips 12 and second clips 13. The first clips 12 and the second clips 13 correspond to the heat dissipation vents 10. The inner walls on both sides of the heat dissipation vents 10 of the upper chassis 1 are provided with rotating holes 11. A return force shielding assembly 3 is rotatably connected between two rotating holes 11. The return force shielding assembly 3 includes a shielding plate 31. A fan 14 is installed between the first clips 12 and the second clips 13. An outward push assembly 4 is installed between the rotating part of the fan 14 and the inner walls of the first clips 12 and the second clips 13. The outward push assembly 4 pushes the shielding plate 31 outward.

[0036] Specifically, the intelligent management system structure in this invention is similar to that of existing intelligent management systems. The main improvement lies in using low-cost methods to enhance the heat dissipation of the industrial chassis of the 5G-enabled intelligent management equipment. Commands are sent by the remote control monitoring module 6, which controls the intelligent automation module 8 to manage the mechanical equipment via the communication module 5. The communication module 5 transmits signals based on the edge computing / edge AI module 7 and the security and privacy protection module 8. The communication module 5 in this invention achieves reliable, high-bandwidth, and low-latency communication and connectivity. This includes optimizing 5G network performance to ensure fast data transmission and stable communication between devices, while also considering the specific needs of industrial scenarios: such as massive connectivity and mobile device management. 5G technology provides higher data transmission rates and bandwidth, supporting real-time data transmission and fast communication between industrial devices. We intend to conduct in-depth research on new modems and multi-antenna technologies (such as Massive MIMO) to increase signal capacity and coverage; high-speed mobile communication: 5G technology provides higher data transmission rates and bandwidth, supporting real-time data transmission and fast communication between industrial devices. We plan to conduct in-depth research on new modems and multi-antenna technologies (such as Massive MIMO) to increase signal capacity and coverage. 5G technology can support large-scale device connectivity, enabling widespread interconnection between industrial equipment. Key technologies include Internet of Things (IoT) technology, Narrowband Internet of Things (NB-IoT) technology, and device-to-device (D2D) communication to meet the needs of a large and dispersed number of industrial devices. Network slicing technology in 5G can divide network resources into multiple independent virtual networks, providing customized network services for different industrial applications. This allows industrial equipment to obtain appropriate bandwidth, latency, and security services according to its own needs.

[0037] The remote control and monitoring module 6 utilizes 5G technology to enable remote control and monitoring of industrial equipment. Through the 5G network, remote maintenance, fault diagnosis, and equipment debugging can be achieved, reducing the need for on-site repairs and saving time and costs.

[0038] The edge computing / edge AI module 7 deploys computing and artificial intelligence algorithms at the edge of industrial equipment to improve real-time performance and reduce reliance on central cloud computing. This enables industrial equipment to make rapid decisions, perform data analysis and processing, thereby enhancing its intelligence. 5G technology, combined with the capabilities of edge computing and artificial intelligence (AI), pushes computing and decision-making closer to the equipment. This allows for real-time data processing, model inference, and decision-making near the equipment, reducing reliance on central cloud computing, improving response speed, and enhancing privacy protection.

[0039] The security and privacy protection module 8 ensures the security and privacy of industrial equipment in 5G networks. This includes research on communication encryption, authentication, access control, and data security to prevent unauthorized access and data leakage.

[0040] The intelligent automation module 9 connects industrial equipment to a 5G network, enabling the equipment to become intelligent and automated. Utilizing the high-speed and reliable connectivity provided by the 5G network, the equipment can exchange data, receive instructions, and respond in real time, thereby achieving automated operation and collaborative work.

[0041] Based on the aforementioned innovative application scenarios and business models leveraging 5G technology, more value can be brought to the industrial equipment sector. For example, 5G networks can enable collaboration and resource optimization between devices, promoting flexible production and customized manufacturing;

[0042] Leveraging the high bandwidth and low latency of 5G networks, autonomous collaboration and swarm intelligence among industrial machinery can be achieved. Multiple machines can share data and instructions in real time, collaboratively completing complex tasks and improving production efficiency and flexibility. 5G technology provides high-speed and stable connectivity for virtual reality (VR) and augmented reality (AR), offering new ways to interact and operate industrial equipment. For example, AR technology can provide real-time guidance and information display during training and maintenance. Combined with the Internet of Things (IoT) and edge computing, 5G technology enables intelligent manufacturing and optimized production processes. Through real-time monitoring and analysis of equipment, processes, and products, intelligent scheduling, predictive maintenance, and resource optimization can be achieved, improving production efficiency and quality. Data-driven decision-making and optimization: 5G technology supports large-scale data transmission and processing, enabling industrial equipment to acquire vast amounts of real-time data. This data can be used for data analysis, machine learning, and training of artificial intelligence algorithms, thereby achieving data-driven decision-making and optimization and improving production efficiency.

[0043] In use, the industrial chassis of the 5G technology smart management equipment for industrial parks of this invention can have temperature sensors installed inside the upper chassis 1 and lower chassis 2. These temperature sensors can be electrically connected to an external main controller. If the temperature inside the upper chassis 1 and lower chassis 2 is too high, the temperature sensors detect the temperature and compare it with a preset threshold. Based on this comparison result, if the temperature exceeds the preset threshold, the main controller receives a signal and starts the fan 14. The fan 14 pushes the baffle 31 to rotate via the external push assembly 4, thereby opening the heat dissipation vent 10. Fan 14 can exhaust heat from the upper chassis 1 and lower chassis 2 through heat dissipation vent 10. When the temperature inside the upper chassis 1 and lower chassis 2 drops, fan 14 stops working, and baffle 31 rotates to block heat dissipation vent 10, thus preventing dust from entering the upper chassis 1 and lower chassis 2. The rotation of baffle 31 is controlled by the rotation and stop of fan 14, thereby controlling the opening and closing of heat dissipation vent 10. No other driving equipment is required, reducing manufacturing costs. Heat dissipation vent 10 is parallel to fan 14, thereby improving the heat dissipation effect inside the upper chassis 1 and lower chassis 2.

[0044] The fan 14 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be described again in the instruction manual.

[0045] Specifically, the push-out assembly 4 includes a worm gear 46, a connecting rod 41, multiple limiting rods 47, and a rack 49. One end of the worm gear 46 is fixedly connected to the rotating part of the fan 14. The connecting rod 41 is rotatably connected to the inner wall of the first clamp 12. A rotating block 42 is fixedly connected to the outer wall of the connecting rod 41. A bearing 43 is installed on the outer wall of the rotating block 42. A worm wheel 44 that meshes with the worm gear 46 is installed on the outer wall of the bearing 43. A limiting frame 411 is fixedly connected to the inner wall of the worm wheel 44. A pawl 412 is rotatably connected to the inner wall of the limiting frame 411. A ratchet groove 414 is opened on one end face of the rotating block 42. The pawl 412 and the ratchet groove 412 are connected to the ratchet groove 49. The slot 414 engages, and the side wall of the limiting frame 411 is fixedly connected to a spring piece 413 that limits the pawl 412. The other end of the rotating block 42 is fixedly connected to a gear 45. Multiple limiting rods 47 are rotatably connected to the inner wall of the second clamp 13. The side wall of the rack 49 is provided with a sliding groove 410. The rack 49 is slidably connected to the outer wall of the limiting rod 47 through the sliding groove 410. Two retaining rings 48 are fixedly connected to the outer wall of the limiting rod 47. The rack 49 is located between the retaining rings 48. The gear 45 meshes with the rack 49. One end of the rack 49 slides against the inner wall of the baffle plate 31. The rack 49 moves against the baffle plate 31. When fan 14 rotates, it drives worm gear 46 to rotate, worm gear 46 and worm wheel 44 to rotate. The rotation of worm wheel 44 drives pawl 412 to rotate through multiple limit brackets 411. Pawl 412 drives rotating block 42 to rotate by meshing with ratchet groove 414. Rotating block 42 drives gear 45 to rotate, gear 45 drives rack 49 to move. The sliding groove 410 on rack 49 slides on the outer wall of limit rod 47. Multiple limit rods 47 restrict and support rack 49. The retaining ring 48 on the outer wall of limit rod 47 positions and restricts rack 49. Rack 49 pushes baffle plate 31 to rotate, causing heat dissipation vents to rotate. When the fan 14 stops rotating, the baffle 31 rotates, which drives the rack 49 to move back. The gear 45 rotates, which drives the rotating block 42 to rotate. Due to the restriction of the worm 46, the rotating block 42 rotates in reverse. The ratchet 414 does not drive the pawl 412 to move when it rotates. The pawl 412 slides on the outer wall of the rotating block 42. The spring 413 always restricts the pawl 412, so that the pawl 412 fits against the outer wall of the rotating block 42, thereby achieving the closing of the heat dissipation port 10 by the rotation of the baffle 31. The overall structure is simple, easy to use, requires no additional drive equipment, and has low manufacturing cost.

[0046] Specifically, the return shielding assembly 3 also includes a rotating rod 32, with both ends of the rotating rod 32 passing through two rotating holes 11 respectively. Both ends of the rotating rod 32 are fitted with torsion springs 33 for rotating the rotating rod 32. The torsion springs 33 are located inside the rotating holes 11. The shielding plate 31 is fixedly connected to the outer wall of the rotating rod 32. After the rack 49 pushes the shielding plate 31 outward, the shielding plate 31 rotates, driving the rotating rod 32 to rotate. The rotating rod 32 compresses the torsion springs 33. When the rack 49 moves back, under the elastic force of the torsion springs 33, the shielding plate 31 rotates to shield the heat dissipation port 10.

[0047] Specifically, the return shield assembly 3 also includes a limiting plate 36, which is fixedly connected to the inner top wall of the heat dissipation vent 10 of the upper chassis 1. The limiting plate 36 blocks and restricts the shield 31. When the shield 31 rotates to block the heat dissipation vent 10, the limiting plate 36 blocks and restricts the shield 31 when the shield 31 is rotated to a vertical position, so that the shield 31 can completely block the heat dissipation vent 10, thereby improving the dust protection of the upper chassis 1 and the lower chassis 2.

[0048] Specifically, the return shield assembly 3 also includes a bottom filter plate 34 and two side filter plates 35. One side of the side filter plate 35 and one end of the bottom filter plate 34 are fixedly connected to the inner wall of the shield plate 31, and the other side of the side filter plate 35 is fixedly connected to the upper surface of the bottom filter plate 34. When the shield plate 31 rotates outward, it drives the side filter plate 35 and the bottom filter plate 34 to rotate, causing the bottom filter plate 34 to tilt. Thus, when the fan 14 exhausts the heat from the upper casing 1 and the lower casing 2, the heat passes through the side filter plate 35 and the bottom filter plate 34. The side filter plate 35 and the bottom filter plate 34 can block mosquitoes from the outside, preventing them from entering the upper casing 1 and the lower casing 2, thereby improving the protection of the interior of the upper casing 1 and the lower casing 2.

[0049] Specifically, the end of the bottom filter plate 34 away from the baffle plate 31 is a sloping structure, and this end of the bottom filter plate 34 abuts against the inner bottom surface of the heat dissipation vent 10 on the lower casing 2; when the bottom filter plate 34 rotates outward, one end of its bottom surface abuts against the inner bottom surface of the heat dissipation vent 10 on the lower casing 2, thereby restricting the baffle plate 31 and maintaining the stability of the return force baffle assembly 3.

[0050] Specifically, the contact end between the rack 49 and the baffle plate 31 is an arc-shaped structure; when the rack 49 pushes the baffle plate 31 outward, the arc-shaped end of the outer end of the rack 49 contacts and slides with the baffle plate 31, reducing the resistance between the rack 49 and the baffle plate 31, reducing friction, and improving service life.

[0051] Specifically, mounting slots 15 are provided on both sides of the fan 14, and the first clip 12 and the second clip 13 are fitted into the mounting slots 15. The upper chassis 1 and the lower chassis 2 are detachable. The fan 14 is installed by inserting the first clip 12 and the second clip 13 into the mounting slots 15 on its outer wall, thereby realizing the installation of the fan 14, making it convenient to disassemble and install the fan 14, and facilitating maintenance and replacement.

[0052] Specifically, there are two fans 14, and the two fans 14 blow air in opposite directions; one fan 14 blows air into the upper chassis 1 and the lower chassis 2, and the other fan 14 blows air out of the upper chassis 1 and the lower chassis 2, so as to realize the air circulation inside the upper chassis 1 and the lower chassis 2 and improve the heat dissipation effect inside the upper chassis 1 and the lower chassis 2.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
