Description

Technical Field

[0001] The present invention relates to the field of BIM-based multifunctional access control devices, and in particular to a BIM-based multifunctional access control device. Background Art

[0002] The BIM-based access control device is an innovative application that combines the traditional access control system with advanced BIM technology, and has many unique features and advantages.

[0003] At present, access control devices in large venues and industrial areas mostly release vehicles or personnel by lifting and lowering bars. Compared with traditional access control systems, BIM-based access control devices can achieve more intelligent operation and monitoring. By integrating the access control system with the building automation system and using the BIM model as a platform for data interaction and visualization, the operating status of the access control equipment can be monitored in real time. 、 The entry and exit of personnel and the linkage with other security equipment. For example, when someone forcibly destroys the access control equipment, the system can immediately locate the scene of the incident through the BIM model, and trigger the alarm device and related cameras to record the video at the same time. The security personnel can obtain accurate information and take corresponding measures in the first time. During the access control blocking process, the position for vehicle driving is unsupervised and it is possible that someone drills in from the bottom or climbs over to enter the venue. Moreover, in the face of strong winds and other environments, because the blocking rod is only supported by the transmission surface, it is also possible that deformation, bending and breaking may occur. Based on the above-mentioned situations, we found that the BIM-based multifunctional access control device in the prior art is difficult to avoid the above problems at the same time. Therefore, we propose a BIM-based multifunctional access control device that can effectively prevent people from climbing over and can effectively protect the structure when facing strong winds and other weather conditions or even collisions with external vehicles.

[0008] The impact plate is arranged on the outer side of the gate plate, the inner side of the gate plate is rotatably connected with a sliding shaft, the gate plates are rotatably connected with each other through the sliding shaft, a buffer sheet is fixedly connected to the side of the impact plate close to the gate plate, and a buffer box is fixedly connected to the side of the gate plate close to the impact plate;

[0009] The meshing teeth are fixedly connected to the top of the inner wall of the transmission beam, the inner side of the transmission beam is movably connected to the transmission shaft, the end of the transmission shaft away from the isolation column is rotatably connected to a limit plate, the side of the limit plate close to the transmission beam is slidably connected to the transmission beam, the side of the limit plate away from the transmission shaft is fixedly connected to a driving motor, the output end of the driving motor passes through the transmission beam and is bolted to the transmission shaft, the outer side of the transmission shaft is fixedly connected to a gear, and the side of the gear close to the meshing teeth is meshed with the meshing teeth;

[0010] Two sets of pedestrian racks are installed on opposite sides of the two wall panels;

[0011] A sunshade shed is fixedly connected to the top of the pedestrian frame, a side of the bottom of the sunshade shed away from the pedestrian frame is fixedly connected to a support frame, and a side of the support frame close to the pedestrian frame is rotatably connected to a blocking door through an electric rotating shaft;

[0012] The BIM-based smart construction site system is used to extract information related to access control devices from the BIM model when it is necessary to query or analyze it, thereby achieving centralized management and effective use of information and realizing data interaction with other subsystems in the smart construction site system.

[0013] In one embodiment, a door access controller is fixedly connected to one side of the pedestrian frame close to the support frame, and a fill light is fixedly connected to one side of the support frame close to the pedestrian frame.

[0014] In one embodiment, an inner cylinder is fixedly connected to the inner side of the buffer box, a connecting piece is slidably connected to the inner side of the inner cylinder, and a side of the connecting piece close to the buffer piece passes through the buffer box and is fixedly connected to the buffer piece.

[0015] In one embodiment, a spring is fixedly connected to the right side of the connecting plate, a side of the spring away from the buffer plate is fixedly connected to the buffer box, and a flow hole is opened on the inner side of the inner cylinder.

[0016] In one embodiment, an inner groove is formed on the inner side of the gate plate, and a window plate is rotatably connected to the inner side of the inner groove.

[0017] In one embodiment, an extension groove is provided on the inner side of the transmission beam, and the inner side of the extension groove contacts the transmission shaft.

At this time, the top transmission shaft rotates, dragging the remaining gate plates along the transmission beam. It rises until it is suitable for vehicles to travel along. When the transmission shaft moves, the sliding sleeve and the limit block connected thereto will move along the inner side of the isolation column, which not only plays the role of limiting the movement of the structure, but also makes it difficult to tilt or deform in windy weather because both sides of the gate are supported. When the gate falls, the bottom gap is small and the top is high, so it is not easy to be drilled into or climbed over. In the event of a collision, the external collision will directly contact the impact plate, and there is a certain displacement space between the impact plate and the gate plate, which will also buffer the impact force when the impact plate is displaced through the buffer sheet and the buffer box.

DETAILED DESCRIPTION

[0034] In order to achieve the purpose of the embodiments of the present invention, 、 The technical solutions and advantages are more clearly understood. The technical solutions in the embodiments of the present invention will be explained in detail below in conjunction with the accompanying drawings in the embodiments of the present invention. 、 It is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Combine the following Figures 1 to 8 The present invention describes a BIM-based multifunctional access control device.

[0036] like Figure 1 Hezhi Figure 6 As shown, in one embodiment, a multifunctional access control device based on BIM includes:

[0037] The main frame 100 has wall panels 110 bolted to both sides;

[0038] The gate plate 200 is arranged between the two wall plates 110 and is located at the bottom of the main frame 100. A separation column 210 is arranged on the side of the gate plate 200 away from the wall plate 110. A transmission beam 220 is arranged on the side of the gate plate 200 away from the separation column 210. Three transmission shafts 230 are arranged between the separation column 210 and the transmission beam 220. The three transmission shafts 230 are rotatably connected to the inner sides of the top gate plate 200, the bottom gate plate 200 and the middle gate plate 200 respectively.

[0039] The impact plate 231 is arranged on the outer side of the gate plate 200, and the inner side of the gate plate 200 is rotatably connected with a sliding shaft 232. The gate plates 200 are rotatably connected through the sliding shaft 232. A buffer sheet 233 is fixedly connected to the side of the impact plate 231 close to the gate plate 200, and a buffer box 234 is fixedly connected to the side of the gate plate 200 close to the impact plate 231.

[0040] The meshing teeth 221 are fixedly connected to the top of the inner wall of the transmission beam 220. The inner side of the transmission beam 220 is movably connected to the transmission shaft 230. The end of the transmission shaft 230 away from the isolation column 210 is rotatably connected to the limiting plate 222. The side of the limiting plate 222 close to the transmission beam 220 is slidably connected to the transmission beam 220. The side of the limiting plate 222 away from the transmission shaft 230 is fixedly connected to the driving motor 223. The output end of the driving motor 223 passes through the transmission beam 220 and is bolted to the transmission shaft 230. The outer side of the transmission shaft 230 is fixedly connected to the gear 224. The side of the gear 224 close to the meshing teeth 221 is meshed and connected to the meshing teeth 221.

[0041] Two sets of pedestrian racks 300 are respectively installed on opposite sides of the two wall panels 110;

[0042] The sunshade shed 310 is fixedly connected to the top of the pedestrian frame 300, and a support frame 320 is fixedly connected to the bottom of the sunshade shed 310 away from the pedestrian frame 300. The side of the support frame 320 close to the pedestrian frame 300 is rotatably connected to a blocking door 330 through an electric shaft;

[0043] The BIM-based smart construction site system is used to extract information related to access control devices from the BIM model when it is necessary to query or analyze it, thereby achieving centralized management and effective use of information. At the same time, it can interact with other subsystems in the smart construction site system, including but not limited to personnel management systems and security monitoring systems, through the BIM model.

[0044] The above-mentioned BIM-based multifunctional access control device supports the structure through the main frame 100 and the wall panel 110. The gate plate 200 is used as a blocking device for vehicle carriers when in use, and the isolation column 210 is used as a separation position for the two-way parking space. At the same time, the lifting and lowering of the gate plate 200 are limited, and the movement of the gate plate 200 is driven by the transmission beam 220. When lifting, the gate plate 200 installed on the transmission beam 220 through the transmission shaft 230 moves along with the movement of the transmission shaft 230. The top drive motor 223 drives the transmission shaft 230 while the gear 224 connected thereto also rotates and meshes with the meshing teeth 221. At this time, the top transmission shaft 230 rotates, dragging the remaining gate plates 200 up along the transmission beam 220 until they can be used for vehicles to travel. When the transmission shaft 230 moves, the sliding sleeve 213 and the limit block 212 connected thereto will move along the inner side of the isolation column 210, which not only plays a role in the movement of the structure The dynamic limit effect is that in strong winds and other weather conditions, because both sides of the gate 200 are supported, it is not easy to tilt or deform. Because the bottom gap of the gate 200 is small and the top is high when it falls, it is not easy to be drilled into or climbed over. In the event of a collision, the external collision will directly contact the impact plate 231, and there is a certain displacement space between the impact plate 231 and the gate 200. When the impact plate 231 is displaced through the buffer sheet 233 and the buffer box 234, it will also buffer the impact force. In the smart construction site system, all data related to the access control device are integrated in the BIM model. The access control device component can be found directly in the BIM building information model, and its stored attribute information can be viewed to quickly obtain data such as the actual parameters of the structure. This centralized data storage method improves the efficiency of information query. In terms of safety monitoring of smart construction sites, the status information of the access control device, including but not limited to whether the gate is opened and closed normally, 、 Whether the blocking door is damaged, etc. can be transmitted to the safety monitoring system through the BIM model. Based on this information, combined with the building layout and dangerous area division in the BIM model, the safety monitoring system can judge potential safety risks more promptly and accurately.

[0045] In one embodiment, a door access controller 321 is fixedly connected to one side of the pedestrian frame 300 close to the support frame 320 , and a fill light 322 is fixedly connected to one side of the support frame 320 close to the pedestrian frame 300 .

[0046] Specifically, by setting up the access control controller 321 for personnel to perform magnetic card recognition, the fill light 322 can facilitate personnel to avoid difficulty in observing the access control position when the surrounding light is insufficient.

[0048] Specifically, by arranging the inner cylinder 235 to cooperate with the connecting piece 236, when the buffer piece 233 is displaced due to the force of the impact piece, the connecting piece 236 connected to the buffer piece 233 will be displaced along the inner cylinder 235, thereby limiting the moving position of the impact piece.

[0049] In one embodiment, a spring 237 is fixedly connected to the right side of the connecting piece 236 , and a side of the spring 237 away from the buffer piece 233 is fixedly connected to the buffer box 234 . A flow hole 238 is opened on the inner side of the inner cylinder 235 .

[0050] Specifically, by setting the spring 237 in conjunction with the flow hole 238, when the connecting piece 236 moves inside the inner tube 235, the viscous fluid medium filled inside will be pushed to flow from the position of the flow hole 238 to achieve a damping effect, effectively buffering the impact force, further improving the anti-collision performance of the structure, and when the force stops, the spring 237 will rebound to push the structure to reset.

[0051] In one embodiment, an inner groove 240 is formed on the inner side of the gate plate 200 , and a window plate 241 is rotatably connected to the inner side of the inner groove 240 .

[0052] Specifically, by providing an inner groove 240 for installing the window panel 241, when the front side of the device is exposed to wind, it can be buffered by the contact with and displacement of the impact plate. When the rear side of the device is exposed to wind, the airflow will blow the window panel 241 to rotate along the inner groove 240 and allow airflow to pass through, thereby reducing the damage caused by the airflow to the structure.

[0053] In one embodiment, an extension slot 225 is formed on the inner side of the transmission beam 220 , and the inner side of the extension slot 225 contacts the transmission shaft 230 .

[0054] Specifically, by providing the extension groove 225, when the transmission shaft 230 moves, the extension groove 225 in contact therewith can assist in limiting the position, thereby preventing the structure from tilting along the inside of the isolation column 210, which may make it difficult to reset the structure.

[0055] In one embodiment, the inner side of the isolation column 210 is slidably connected to the limit block 212 , the bottom of the limit block 212 is fixedly connected to the sliding sleeve 213 , and the inner side of the sliding sleeve 213 is rotatably connected to the transmission shaft 230 .

[0056] Specifically, by providing the sliding sleeve 213 , when the transmission shaft 230 rotates, the transmission will be smoothly transmitted along the inside of the sliding sleeve 213 , and the limiting block 212 slides on the inner side of the isolation column 210 to limit the movement of the transmission shaft 230 .

[0057] In one embodiment, the inner side of the limiting block 212 is rotatably connected to a pulley 214 , and the top of the pulley 214 is slidably connected to the isolation column 210 .

[0058] Specifically, by providing the pulley 214 , the limiting block 212 can slide more smoothly on the inner side of the isolation column 210 , and is less likely to get stuck.

[0059] In one embodiment, a display 323 is fixedly connected to the bottom of the main frame 100 and the bottom of the awning.

[0060] Specifically, by setting a display 323 at the bottom of the main frame 100, the vehicle driver can observe the BIM-based three-dimensional model of the building displayed in the display 323, exchange data with the access control system, or provide people walking in the sunshade 310 with the access control status.

[0061] In one embodiment, the inner wall of the sunshade shed 310 and the opposite side of the two wall panels 110 are fixedly connected with image acquisition cameras 324 .

[0062] Specifically, by setting up an image acquisition camera 324, information such as the appearance or license plate of the vehicle and the internal personnel can be collected for the background system to identify and upload, or used to collect facial features of pedestrians for verification with the access control system to facilitate release or blocking.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
