Description

Technical Field

[0001] This invention relates to the field of intelligent management technology for commercial spaces, and more specifically, to an intelligent customer flow guidance and dynamic exposure system for business information, as well as access control terminal equipment. Background Technology

[0002] With urban development, underground commercial spaces are becoming increasingly large and complex, and customers often face the following problems in these spaces: 1. Difficulty finding stores: It is easy to lose one's sense of direction and it is difficult to quickly find the target store; 2. Information lag: Traditional static signs cannot reflect real-time customer flow and dynamic information of shops (such as discounts and queue status); 3. Poor experience: Blindly weaving through congested areas wastes time and energy, resulting in a poor shopping experience; For merchants and managers: 1. Uneven distribution of hot and cold areas: Customer flow is severely uneven, with a huge gap between "prime locations" and "quiet corners", and the overall space efficiency is not maximized; 2. Lack of data support: It is impossible to grasp accurate customer flow data for the whole situation and individual stores in real time, making it difficult to make scientific decisions and precise marketing.

[0003] 3. Limited customer acquisition methods: There is a lack of effective technical means to intelligently guide entrance traffic to different areas and shops.

[0004] Currently, although some shopping malls use Wi-Fi probes or simple cameras to count customer flow, the data application is superficial and has not been deeply integrated with real-time customer guidance, personalized recommendations, and dynamic route planning to form a closed-loop intelligent service and operation system.

[0017] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, "a" or "one," etc., do not indicate a quantity limitation, but rather indicate the existence of at least one. In the implementation of this application, "and / or" describes the association relationship of related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more. For example, multiple positioning posts refer to two or more positioning posts. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] The present invention will now be described in detail.

[0019] Example 1: The intelligent customer flow guidance and business information dynamic exposure system of this invention aims to provide a system that can display the heat distribution of customer flow in real time and intuitively, enhance customers' environmental awareness, and intelligently recommend shops and plan the optimal route based on customers' personalized needs and real-time customer flow status. At the same time, it can dynamically expose shop information, balance the distribution of customer flow in commercial spaces, and improve the overall operational efficiency mechanism. It can provide merchants and managers with refined real-time customer flow data and analysis tools. This system mainly includes a distributed perception layer, which consists of thermal imaging cameras deployed in the passageways of the commercial street, customer flow statistics cameras deployed at the entrances of shops, and Bluetooth beacons deployed in the shops, used to collect real-time data on pedestrian density, movement direction, and speed. The central processing layer receives data from the perception layer, performs data fusion, cleaning and analysis, and executes passenger flow density calculation, congestion judgment, personalized recommendation algorithm and dynamic route planning algorithm. The cloud data layer stores real-time customer flow data, static information of shops, user preference models, and historical trajectory data. The interactive display layer includes display terminals located at the business entrance and used in conjunction with users' mobile devices; The display terminal dynamically renders a multi-layered heat map based on real-time data and generates a dynamic QR code that can be accessed by an app. Users scan the dynamic QR code through their mobile app, and then enter their consumption needs (such as category, taste, and price). The central processing layer recommends a list of eligible shops based on multiple factors such as demand matching degree, real-time customer flow saturation of shops, and user historical preferences. It also automatically generates an optimized route to avoid the current congested area and reach the target shop, providing real-time navigation on the app map. Specifically, the multi-layered heat map covers streets and shops.

[0020] Specifically, dedicated thermal imaging cameras are installed at key nodes such as intersections of all commercial streets and entrances and exits in the middle of straight sections. These thermal imaging cameras ensure that all public passage areas are covered without any blind spots. In addition, miniature customer flow cameras are installed inside the entrance of each shop to count the number of people entering and leaving the shop and to sense the approximate density of people inside the shop. Install a large number of low-power Bluetooth beacons in concealed locations on the ceiling or walls. These transmitters do not collect data, but only continuously broadcast their own identification codes to provide a basis for subsequent mobile terminal positioning. Specifically, the central processing layer receives data streams from all front-end devices (cameras, Bluetooth signals), classifies and organizes them according to device type and location information, and assigns precise time tags to each data item. Then, it performs real-time analysis on the organized data. For street data, it calculates the current pedestrian density, average speed of pedestrian movement, and main direction of pedestrian movement for each street. For shop data, it calculates the current real-time number of people in each shop and the degree of crowding relative to the shop area. When a customer’s specific needs are received, the system takes into account a variety of factors, such as the matching degree of store type, the current level of congestion, the distance from the customer’s location, and store reviews, and filters out the most suitable store list. The stores are then sorted according to their overall ratings. Based on the store selected by the customer and combined with the real-time pedestrian flow distribution map of the entire commercial space, the system automatically calculates a walking route that can reach the store quickly while avoiding congested areas as much as possible. This route is not fixed and will be dynamically adjusted as pedestrian flow changes. Specifically, the display terminals are set up in prominent positions at each main entrance of the commercial area. They are large, high-definition display terminals. The screens mainly display a simplified map of the entire commercial area. Different streets and shops on the map are displayed in different colors to show their current congestion status (e.g., green represents smooth traffic and red represents congestion), making it easy for people to understand at a glance. Customers can access the APP by scanning the dynamic QR code on the display terminal. Within the APP, they can input their shopping needs, view the stores recommended by the system and the planned routes, and enjoy real-time walking navigation services. The application interface will clearly show whether the route ahead is congested and the current waiting status of the target store. More specifically, the central processing layer integrates the pedestrian flow data of streets and shops onto an electronic map. Streets are represented by colored lines of different widths, with colors ranging from blue to green to yellow to red, representing pedestrian density from low to high. Each shop is represented by a colored icon, with the intensity of the icon's color indicating the real-time number of people in that shop. Users can see "where there are many people and which shops are busy" at a glance on the map. The colors on the map are not static. The system is set to a fixed refresh cycle (e.g., every 10 seconds). The data processing layer pushes the latest analysis results to the display terminal, and the colors on the map will change smoothly accordingly. This dynamic change keeps the information up-to-date. When the system makes recommendations to users, it doesn't just simply match keywords. It weighs the pros and cons. For example, when two similar hot pot restaurants meet the customer's needs, the system won't just recommend the more famous one. Instead, it will prioritize recommending the one with fewer people in line and relatively less crowded space. At the same time, it will also consider the distance between the store and the customer's current location to avoid recommending a store that requires traversing the entire crowded mall. This mechanism satisfies customer needs while subtly guiding customer flow from popular areas to potential areas, thus balancing the overall business ecosystem of the mall.

[0021] Let's take Ms. Li as an example to understand the specific workflow of the system in more detail: S1. When Ms. Li entered the mall, she first saw the display terminal at the entrance. The map on the display terminal showed that the food area on the left was mostly orange and red, while the retail area on the right was mainly green and yellow. S2. She wanted to have lunch, so she scanned the QR code on the display terminal with her mobile phone. The phone automatically opened the mall's smart guidance application. After the application started, it immediately obtained the location information that Ms. Li entered from the south gate.

[0022] S3. Ms. Li entered "Japanese cuisine" into the application's search box.

[0023] S4. A few seconds later, the app displayed a list of three or four Japanese restaurants. The top recommendation wasn't the most famous one, but a restaurant called "Zhuting." The app indicated that this restaurant had a "4.5-star taste rating, no waiting time, and is approximately 350 meters away." This was the result of the system's overall balancing—although "Zhuting" wasn't the most famous, it had a high vacancy rate and was close to the South Gate.

[0024] S5. Ms. Li selected "Bamboo Pavilion" and clicked "One-Click Navigation". The application immediately planned a route. The route did not go directly through the crowded food area on the left, but guided her to go to the right first, through the retail area, and then turn to the area where "Bamboo Pavilion" is located. On the route map, the planned route was shown in green.

[0025] S6. Ms. Li followed the navigation and walked halfway when her phone vibrated to notify her: "Due to the increased visitor flow in the passage ahead due to a temporary exhibition, you have been switched to an alternative route." The navigation lines on the screen were then updated, guiding her to another slightly longer but smoother corridor.

[0026] S7. Ms. Li successfully arrived at "Bamboo Pavilion" and dined there. During her walk and meal, all the cameras she passed were silently updating their data. The "Bamboo Pavilion" she chose also saw a change in customer flow data due to this navigation. The merchant's backend saw the store entry records brought about by this guidance, and the heat value of the area where "Bamboo Pavilion" is located on the mall's control panel data chart showed a slight increase.

[0027] Example 2: Please see Figures 1-8 The present invention also discloses an access control terminal device, including an access control station, a terminal housing 1 on which a display terminal is installed, an access control rod 2 with one end hinged to the terminal housing and the other end overlapping the access control station, a cleaning mechanism 3 on the terminal housing 1 for cleaning the display terminal 11, and a drive assembly 4 installed in the terminal housing 1 and in transmission cooperation with the access control rod 2 and the cleaning mechanism 3.

The liquid after the cleaning roller 32 cleans the display terminal 11 will enter the filter chamber 35 for filtration and then be delivered to the liquid storage chamber 341. A filter screen 351 is provided in the filter chamber 35. The drive assembly is installed on the filter chamber 35.

[0030] The drive assembly 4 includes a motor 41 installed in the storage box 5, an input shaft D42 horizontally connected to the output shaft of the motor 41, a worm gear B43 connected to the input shaft D42, a worm wheel B431 driven by the worm gear B43, a rotating shaft 44 coaxially connected to the worm wheel B431 and connected to one end of the access control bar 2, and a transmission component 45 driven by one of the input shafts D42 and the vertical drive component 33; the axial direction of the rotating shaft 44 is horizontally arranged and perpendicular to the axial direction of the input shaft D42; the rotating shaft 44 is rotatably engaged with the storage box 5; The transmission component 45 includes a transmission gear A451 coaxially mounted on the outside of the input shaft D42, an input shaft C452 parallel to the input shaft D42, a transmission gear B453 coaxially mounted on the input shaft C452 and meshing with the transmission gear A451, an input shaft E454 coaxially mounted with the input shaft C452, a ratchet assembly 455 disposed between the input shaft C452 and the input shaft E454, a worm gear A456 disposed on the input shaft E454, a worm wheel A457 drivingly engaging with the worm gear A456, and an input shaft B458 coaxially connected to the worm wheel A457; the input shaft B458 is drivingly connected to the vertical drive component.

[0031] The vertical drive component 33 includes a bevel gear B331 coaxially connected to the input shaft B458, a bevel gear A332 meshing with the bevel gear B331, an input shaft A333 coaxially connected to and located above the bevel gear A332, a reciprocating screw 334 screwed to the motion table 31 and connected at one end to the input shaft A333, a guide column 335 parallel to the reciprocating screw 334 and fitted inside the motion table 31, a transmission gear C336 disposed at one end of the cleaning roller 32, and a rack 337 installed in the terminal housing 1 and meshing with the transmission gear C336; the rack 337 and the reciprocating screw 334 are arranged vertically.

[0032] In some possible implementations, the terminal housing 1 includes a housing for mounting the display terminal 11 and a storage box 5 mounted at the bottom of the housing for storing the cleaning mechanism 3; the filter chambers 35 are located at the bottom of the storage box 5 and are interconnected; the liquid storage chamber 341 is located at the bottom of the filter chamber 35, and the storage box 5 is provided with a movement port 51 through which the motion platform 31 passes; a liquid level sensor is provided in the liquid storage chamber 341; and a storage slot 13 for storing the access control bar 2 is provided on the outside of the housing.

[0033] It should be noted that: The terminal host 12 is connected to the central processing layer in Embodiment 1 via a network. The terminal host 12 is connected to the display terminal 11, which serves as an interactive display, via a data connection. This allows the terminal host 12 to receive data from the central processing layer, process the data, and then finally display the data on the display terminal 11 (displaying a simplified map of the commercial area, with different streets and shops on the map showing their current congestion status in different colors). The terminal housing 1 includes a cleaning mechanism 3 corresponding to the display terminal 11. A storage box 5 is fixedly connected to the bottom of the terminal housing 1. A guide post 335 is fixedly connected to one side of the display terminal 1 on the terminal housing 1. The guide post 335 is vertically oriented, i.e., along the Z-axis. A motion table 31 is slidably connected to the guide post 335. A reciprocating screw 334, which is vertically oriented, is internally threaded onto the motion table 31. The reciprocating screw 334 is located on the other side of the display terminal 11, and the display terminal 11 is located between the reciprocating screw 334 and the guide post 335. A cleaning roller 32, which is axially oriented along the X-axis, is rotatably connected to the motion table 31. The front of the display terminal 11 is used to clean the outer side of the display terminal 11. One end of the roller shaft of the cleaning roller 32 is fixedly connected to the transmission gear C336. A vertically arranged rack 337 is fixedly connected to the terminal housing 1. The rack 337 is meshed with the transmission gear C336. The top surface of the storage box 5 is provided with a movement port 51, and the movement table 31 closes the movement port 51. When the reciprocating screw 334 rotates, the movement table 31 moves upward from the movement port 51, which can then drive the cleaning roller 32 to move up and down vertically. Under the action of the transmission gear C336 and the rack 337, the cleaning roller 32 rotates, thereby cleaning the display terminal 11. The storage box 5 is equipped with a nozzle 343 for spraying cleaning fluid onto the cleaning roller 32. The bottom of the terminal box 1 is equipped with a liquid storage chamber 341 connected to the nozzle 343. A delivery pump 342 is fixedly connected inside the liquid storage chamber 341. The delivery pump 342 is connected to the nozzle 343 through a cleaning fluid delivery pipeline. The delivery pump 342 can pump the cleaning fluid in the liquid storage chamber 341 to the nozzle 343. Then the nozzle 343 sprays the cleaning fluid onto the cleaning roller 32 so that the subsequent cleaning roller 32 can clean the display terminal 11. To save resources, a filter chamber 35 is also provided in the terminal housing 1 above the liquid storage chamber 341. A filter screen 351 is slidably connected in the filter chamber 35. The bottom of the storage box 5 is connected to the filter chamber 35 through a return cleaning fluid pipe, so that the cleaning fluid sprayed by the nozzle 343 can enter the filter chamber 35 through the return cleaning fluid pipe. After the cleaning fluid is filtered by the filter screen 351, the cleaning fluid enters the liquid storage chamber 341. Specifically, after the cleaning roller 32 has finished cleaning the display terminal 11, the cleaning fluid drawn by the delivery pump 342 can also be used to rinse the cleaning roller 32. The rinsed cleaning fluid is also filtered by the filter screen 351 and returned to the storage chamber 341. Of course, a cleaning liquid level sensor is fixedly connected in the liquid storage chamber 341 to detect the cleaning liquid level. A filling pipe is fixedly connected to the liquid storage chamber 341 and communicates with its interior. The filling pipe is connected to the cleaning liquid delivery pipe. An electric control valve is fixedly installed on the filling pipe. The electric control valve and the cleaning liquid level sensor can be connected to the terminal host 12. When the cleaning liquid level detected by the cleaning liquid level detection sensor is lower than the minimum, the electric control valve opens to add cleaning liquid. When the cleaning liquid level reaches the maximum, the electric control valve closes. The terminal box 1 has a storage slot 13 on one or both sides, and an access control bar 2 is rotatably connected in the storage slot 13. An access control table 10 is provided at the commercial entrance in conjunction with the access control bar 2. When the access control bar 2 rotates and comes into contact with the access control table 10, the commercial entrance is closed. The bottom end of the reciprocating screw 334 in the vertical drive component 33 is fixedly connected to an input shaft A333, which is arranged vertically. The input shaft A333 is located inside the storage box 5. A bevel gear A332 is coaxially connected to the input shaft A333. The input shaft A333 inside the storage box 5 is rotatably connected to an input shaft B458 arranged along the Y-axis. The input shaft B is located in the area inside the storage box 5 and one end is fixedly connected to a bevel gear B331. The bevel gear A332 and the bevel gear B331 mesh with each other to realize the rotatable connection between the input shaft A333 and the input shaft B. An input shaft B458, positioned along the Y-axis, is located inside the terminal housing 1. A worm gear A is coaxially and fixedly connected to its other end. A worm A456, positioned along the X-axis, is rotatably connected to the worm gear A457, positioned at the other end of the input shaft B458, inside the terminal housing 1. An input shaft E454, positioned along the X-axis, is fixedly connected to the worm gear A456. A ratchet assembly 455 is provided between the input shaft E454 and its coaxial input shaft C452. The input shafts E454 and C452 are rotatably mounted inside the storage box 5 via a bracket.

[0034] The access control lever 2 is rotatably connected to the storage box 5 via a rotating shaft 44 set along the Y-axis. One end of the rotating shaft 44 is coaxially fixedly connected to a worm gear B431. The storage box 5 is rotatably connected to a worm B43 set along the X-axis. The worm gear B431 meshes with the worm B43. An input shaft D42 set along the X-axis is fixedly connected to the worm B43. A transmission gear A451 is fixedly connected to the input shaft D42, and a transmission gear B453 is fixedly connected to the input shaft C452 at the power input end of the ratchet assembly. The transmission gear A451 and the transmission gear B453 are meshed and connected, and the diameter of the transmission gear A451 is larger than the diameter of the transmission gear B453. A set of motors 41 is fixedly connected inside the terminal housing 1, and the output shaft of motors 41 is poweredly connected to the input shaft D42. When motor 41 rotates in the forward direction, it transmits power to access control lever 2 via worm gear B43, worm wheel B431, and rotating shaft 44 coaxially connected to worm wheel B431. At this time, access control lever 2 rotates to begin closing the mall entrance. Simultaneously, cleaning fluid in storage chamber 341 is sprayed onto cleaning roller 32 via delivery pump 342. Power from motor 41 is transmitted to ratchet assembly 455 via transmission gear A and transmission gear B. Under the action of ratchet assembly 455, power is transmitted to worm gear A456. Worm gear A456 drives worm wheel A457, which is connected to input shaft B458 and coaxial with bevel gear B331, to rotate. Finally, power is transmitted to reciprocating screw 334 via bevel gear A332 and bevel gear B331. In this way, motion table 31 can drive cleaning roller 32 to perform linear motion, and then the rotating cleaning roller 32 cleans display terminal 11. Since a reciprocating screw 334 is used, when the motion table 31 moves to the end of the reciprocating screw 334, the reciprocating screw 334 starts to move in the opposite direction. Under the action of transmission gear A and transmission gear B, when the access control bar 2 closes the entrance to the mall, the motion table 31 drives the cleaning roller 32 to perform a reciprocating motion, and finally the motion table 31 and the cleaning roller 32 enter the storage box 5. When motor 41 rotates in the reverse direction, it drives the access control lever 2 to open. At this time, under the action of ratchet assembly 455, the power cannot be transmitted to the reciprocating screw 334, and the display terminal 11 is not cleaned. It should be noted that when this scheme is adopted and there are two sets of access control levers 2, each set of access control levers 2 has a worm gear B431 fixedly connected to its rotating shaft 44, and each set of worm gears B is rotatably connected to a worm B43 in the terminal box 1. The worm B43 is meshed with the worm gear B, and the two sets of worm gears B43 are connected through the input shaft D42. At this time, the motor 41 is a dual-axis motor 41, and the two sets of output shafts will be coaxial.
