Description

Technical Field

[0001] This invention belongs to the technical field of intelligent indoor positioning terminals and park navigation equipment, specifically relating to a park visual indoor navigation terminal system and navigation method. Background Technology

[0002] Existing indoor park navigation solutions are mainly divided into two categories: mobile APP navigation and fixed signage equipment. They have obvious shortcomings in immersive cultural and tourism activities, fun indoor navigation, and multi-point check-in scenarios.

[0003] In indoor environments, satellite navigation systems receive almost no signals, making accurate navigation impossible. Currently, most indoor positioning solutions on the market rely on wireless signals such as WiFi and Bluetooth for location services, but existing navigation devices often suffer from the following drawbacks: Mobile phone navigation relies on the network, generates numerous pop-up messages that can easily distract visitors, and is unsuitable for a lightweight, handheld gaming experience. It also poses safety risks for children and fails to complement the immersive atmosphere of the park. Furthermore, mobile phone navigation lacks a unified hardware standardization design, resulting in significant differences in navigation experiences across different brands and models, making it difficult to achieve a consistent gaming experience within the park.

[0004] Existing dedicated navigation devices rely solely on on-screen text and arrows to indicate direction, making it impossible for users to intuitively judge the distance and location of target points. This results in high learning costs, poor intuitiveness, and low error tolerance. Users need to repeatedly compare on-screen information with the actual scene, leading to a heavy cognitive burden, and the experience is particularly poor in scenarios where multiple points need to be quickly located.

[0005] Traditional navigation devices typically use a single Bluetooth version or Wi-Fi solution, which cannot simultaneously support high-precision positioning and large-scale networking. Different positioning scenarios have significantly different requirements for communication solutions—high-precision positioning requires centimeter-level ranging capabilities, while large-scale concurrent networking requires the ability to connect a massive number of devices simultaneously. Traditional devices use fixed communication solutions, resulting in non-interchangeable hardware, extremely high upgrade costs, and incompatibility with future next-generation communication technologies.

[0006] Traditional navigation devices only provide route guidance and lack features such as location-sensing check-in, haptic feedback, and scene linkage mechanisms, failing to meet the needs of cultural and tourism parks for task collection, fun challenges, and immersive operations. The lack of interactive feedback between the device and the user results in a dull experience and fails to motivate tourists, especially children.

[0007] Indoor scenarios present complex challenges such as wall obstruction, signal reflection, and multipath effects, making single-base station positioning prone to signal jitter and location drift. When multiple users access the site concurrently, limited network capacity can lead to lag and response delays, failing to meet the stability and real-time requirements for commercial deployment.

[0008] In summary, existing indoor navigation solutions have significant shortcomings in terms of communication adaptability, navigation intuitiveness, interactive experience, and positioning stability. There is an urgent need for an indoor navigation terminal system that features iterable hardware, visualized navigation, interactive functions, and stable positioning. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention aims to solve the problems of significant deficiencies in communication adaptability, navigation intuitiveness, interactive experience, and positioning stability of existing indoor navigation solutions, and provides a visual indoor navigation terminal system and navigation method for parks.

[0010] The technical solution adopted by this invention to solve its technical problem is: A visual indoor navigation terminal system for a park, comprising: The park beacon base station group consists of wireless beacon base stations deployed at multiple locations within the park. Each wireless beacon base station continuously broadcasts its location ID and signal information. A handheld navigation terminal includes a portable housing and a main control module, a wireless communication module, a display module, a card-taking module, and a vibration feedback module disposed within the portable housing; The backend gateway management system is communicatively connected to the handheld navigation terminal. The wireless communication module adopts a multi-protocol universal adaptation architecture, which is compatible with all versions of Bluetooth Low Energy, or can be replaced with a StarFlash communication module or an ultra-wideband communication module. The handheld navigation terminal receives broadcast signals from each wireless beacon base station through the wireless communication module, calculates its own location information, and provides visual directional guidance through the display module; The sensor check-in module is used to cooperate with the wireless beacon base station at each location to complete the location sensor check-in, and the vibration feedback module provides tactile feedback when the check-in is successful or when the user is close to the target location.

[0011] Preferably, in the multi-protocol universal adaptation architecture, the low-power Bluetooth module, the StarFlash communication module, and the ultra-wideband communication module adopt the same installation structure, circuit interface, and functional logic, and can be interchangeably installed in the portable housing; when equipped with a Bluetooth 6.0 module, centimeter-level high-precision channel ranging and positioning are achieved, and when equipped with a Bluetooth 5.4 module, large-scale concurrent networking is achieved.

[0012] Preferably, the display module is a display screen used to display an indoor map, the relative orientation and distance information of the target point, and the display screen is divided into zones for illumination according to the relative orientation and distance of the target point. Different zones correspond to different orientation and distance ranges to form a visual navigation guide.

[0013] Preferably, the handheld navigation terminal scans the signals of multiple surrounding wireless beacon base stations, calculates its own position based on signal strength and ranging information, and determines the relative direction and distance of the target check-in point after matching the preset point data, thereby realizing visual orientation guidance.

[0014] Preferably, the induction check-in module is a check-in sensing contact point set on the portable casing. When the handheld navigation terminal approaches the target location and the induction check-in module completes the sensing match with the wireless beacon base station, the location check-in recognition is realized.

[0015] Preferably, when the check-in is successfully recognized or the handheld navigation terminal approaches the target location to a preset distance, the vibration feedback module automatically starts and provides tactile prompts, and the display module updates the screen status synchronously to complete a visit check-in task.

[0016] Preferably, the background gateway management system is communicatively connected to the handheld navigation terminal, used to receive the check-in records and location information uploaded by the handheld navigation terminal, and to send out point configuration data and task data, so as to realize unified management and data synchronization of multiple terminals.

[0017] Another technical problem to be solved by the present invention is to provide a navigation method for a park-based visual indoor navigation terminal, comprising the following steps: Step S1: The handheld navigation terminal scans the broadcast signals of multiple surrounding wireless beacon base stations through the wireless communication module to obtain the signal strength and ranging information of each base station; Step S2: The main control module performs fusion positioning calculation based on the signal strength and ranging information of multiple base stations to generate the real-time location information of the current handheld navigation terminal; Step S3: The main control module compares the real-time location information with the preset target point data to calculate the orientation and distance of the target point relative to the current location; Step S4: The display module illuminates different areas based on location and distance information to provide users with visual location guidance; Step S5: When the handheld navigation terminal moves close to the target location, the sensor check-in module completes sensor matching with the wireless beacon base station of the target location to realize the check-in recognition of the location; Step S6: After a successful check-in, the vibration feedback module provides tactile feedback, and the display module updates the screen status, completing one check-in task.

[0018] Preferably, in step S4, the display module is illuminated in the following way: the corresponding zone on the display screen is illuminated according to the azimuth angle of the target point relative to the current handheld navigation terminal; the brightness or flashing frequency of the illuminated zone is controlled according to the distance between the target point and the current handheld navigation terminal, with higher brightness or faster flashing frequency as the distance is closer.

[0019] Preferably, in step S3, when there are multiple target points, the main control module sorts them from nearest to farthest by distance and calculates the orientation and distance of each target point in turn, while the display module simultaneously displays the orientation guidance of the nearest multiple target points.

[0020] The beneficial effects of this invention are as follows: The overall structure is compatible with all Bluetooth modules, allowing for low-cost switching between high-precision and high-capacity networking modes. Bluetooth 6.0 enables high-precision channel ranging, meeting centimeter-level indoor positioning requirements; Bluetooth 5.4 enables large-scale PAWR concurrent networking, suitable for scenarios with numerous locations and multiple users simultaneously within a park. It can also be seamlessly upgraded to StarFlash or UWB communication modules. After module replacement, the overall structure, installation location, circuit connections, and functional logic remain completely unchanged, requiring no structural modifications or new molds, demonstrating strong hardware interchangeability. This design fundamentally solves the technical problems of fixed communication solutions and high upgrade costs in traditional equipment, enabling the hardware platform to continuously evolve for the future.

[0021] The display screen can illuminate eight zones based on the relative orientation and distance of the target point. These zones correspond to east, south, west, north, and four oblique angles, allowing users to intuitively determine the target direction by observing the illuminated zones. Distance is indicated by the brightness or color depth of the illuminated zones; closer distances result in higher brightness or darker color. Compared to traditional text and arrow navigation, this invention's visual navigation transforms abstract directional information into intuitive visual signals, significantly reducing navigation learning costs, greatly improving fault tolerance, and greatly enhancing the immersive and engaging experience.

[0022] Integrating a sensor-activated check-in module and a vibration feedback module, this system enables various commercial operation scenarios within the park, including task collection, obstacle course check-ins, and fun treasure hunts. A vibration motor provides tactile feedback upon successful check-in or approaching a target location, which, combined with screen status updates, forms a complete interactive loop of "finding—approaching—checking in—feedback." The backend gateway management system supports unified management and data synchronization across multiple terminals, allowing park operators to flexibly configure check-in tasks and play routes, significantly enhancing the device's interactive capabilities and the park's operational value.

[0023] Employing a multi-base station fusion positioning architecture, the handheld terminal scans signals from multiple surrounding wireless beacon base stations and calculates its own location based on signal strength and ranging information. This effectively overcomes the problems of single-base station positioning being susceptible to signal jitter and multipath effects. The multi-base station fusion positioning architecture is adaptable to complex indoor environments with obstructions, allowing multiple users to be online simultaneously without lag, meeting the stability and real-time requirements for commercial deployment.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Example like Figure 1 As shown, a park-based visual indoor navigation terminal system consists of a park beacon base station group, a handheld navigation terminal 1, and a back-end gateway management system.

[0027] The park beacon base station group consists of wireless beacon base stations deployed at multiple locations within the park. Each wireless beacon base station is installed on a wall, pillar, or scenic spot using a fixed bracket, and continuously broadcasts its location ID and signal information to provide a positioning data source for the handheld navigation terminal 1.

[0028] The handheld navigation terminal 1 is an integrated handheld structure that interacts with various wireless beacon base stations through low-power wireless communication to realize location calculation, visual navigation and location check-in functions.

[0029] The backend gateway management system communicates with the handheld navigation terminal 1 to receive the check-in records and location information uploaded by the handheld navigation terminal 1, and to send out point configuration data and task data to achieve unified management and data synchronization of multiple terminals.

[0030] like Figure 4 As shown, the wireless beacon base station includes a fixed bracket and a base station body. The fixed bracket is installed on a wall, column, or scenic location using expansion bolts or adhesive, and the base station body is fixed to the fixed bracket.

[0031] The base station is equipped with a low-power Bluetooth communication module or a satellite communication module to continuously broadcast its location ID and signal information. The base station's broadcast frequency ranges from 100ms to 1000ms, and its broadcast power ranges from -20dBm to +4dBm, which can be adjusted according to the coverage area and density of the site.

[0032] There are multiple wireless beacon base stations distributed throughout the park's various attractions and access points, with a spacing of 5 to 30 meters between adjacent base stations to ensure comprehensive signal coverage without dead zones. Each wireless beacon base station has a unique ID that corresponds one-to-one with the location data in the backend gateway management system.

[0033] like Figure 2 and Figure 3 As shown, the handheld navigation terminal 1 includes a portable housing 11, a main control module 12, a wireless communication module, a display module, a card-taking module, a vibration feedback module, and a power supply module 13.

[0034] The portable housing 11 is an integrated handheld housing structure, injection molded from engineering plastic, possessing sufficient structural strength and a good grip. A display window 14 is provided on the front of the portable housing 11 for mounting a display module. A card-scanning area is provided on the side or back of the portable housing 11, with the card-scanning module installed inside the card-scanning area. An internal cavity is formed within the portable housing 11 for fixing and mounting the main control module 12, the wireless communication module, the vibration feedback module, and the power supply module 13.

[0035] The portable housing 11 has a charging port on its bottom or side. The charging port is a USB Type-C interface, which is electrically connected to the power supply module 13 to charge the built-in rechargeable battery. The portable housing 11 has a power switch and function buttons on its top or side. The power switch is used to control the power on and off of the handheld navigation terminal 1, and the function buttons are used to perform operations such as confirmation and return.

[0036] The main control module 12 is fixedly installed in the cavity inside the portable housing 11. It is a miniature control circuit board and uses a low-power microcontroller as the core processor. The main control module 12 is electrically connected to the wireless communication module, display module, induction card-taking module, vibration feedback module and power supply module 13, respectively, and is used to uniformly control the coordinated operation of each functional module.

[0037] The main control module 12 has a built-in positioning calculation unit and a navigation guidance unit. The positioning calculation unit is used to calculate the real-time position of the handheld navigation terminal 1 based on the signal strength and ranging information of multiple wireless beacon base stations received by the wireless communication module, using a fusion positioning algorithm. The navigation guidance unit is used to compare the real-time position with preset target point data, calculate the orientation and distance of the target point relative to the current position, and control the display module to perform visual navigation display.

[0038] The wireless communication module is fixedly installed in the cavity inside the portable housing 11 and electrically connected to the main control module 12. It is used to communicate wirelessly with the wireless beacon base station to obtain positioning signals and location information.

[0039] The wireless communication module uses a low-power Bluetooth module, compatible with Bluetooth 5.4, Bluetooth 6.0 and subsequent iterations. When equipped with a Bluetooth 6.0 module, it can achieve high-precision channel ranging, meeting the needs of centimeter-level indoor positioning; when equipped with a Bluetooth 5.4 module, it can achieve large-scale PAWR concurrent networking, meeting the needs of scenarios with a large number of locations and multiple users playing at the same time in the park.

[0040] As an alternative, the wireless communication module can also use a StarFlash communication module or an UltraWideband communication module. The StarFlash communication module achieves lower latency and allows for simultaneous communication with more terminals; the UltraWideband communication module also provides high-precision channel ranging and positioning. After module replacement, the overall structure, installation location, circuit connections, and functional logic remain completely unchanged, achieving universal compatibility with multiple protocols.

[0041] The wireless communication module receives broadcast signals from the wireless beacon base station via an onboard antenna or an external antenna. The scanning period is 100ms to 500ms, which can be adjusted according to positioning accuracy and power consumption requirements.

[0042] The display module is embedded in the display window 14 on the front of the portable housing 11 and is electrically connected to the main control module 12. It is used to display indoor maps, relative orientation and distance information of target points.

[0043] The display module is a color LCD or OLED display, ranging in size from 2.4 inches to 5.5 inches, with a resolution of 240×320 pixels or higher.

[0044] The visualization navigation method of the display module is as follows: based on the azimuth angle of the target point relative to the current handheld navigation terminal 1, the corresponding zone on the display screen is illuminated; based on the distance between the target point and the current handheld navigation terminal 1, the brightness of the illuminated zone is controlled or different colors are displayed. The closer the distance, the higher the brightness or the darker the color; the farther the distance, the lower the brightness or the lighter the color, forming an intuitive visualization guide for direction and distance.

[0045] Specifically, the display module's display area is divided into eight directional zones, corresponding to the eight directions: east, south, west, north, southeast, southwest, northwest, and northeast. When the target point is located in the northeast direction of the handheld navigation terminal 1, the northeast directional zone is lit, while the other zones remain dark or have low brightness. Simultaneously, the brightness or color depth of the lit zones changes accordingly based on the distance to the target point, allowing the user to intuitively determine the direction and distance of the target.

[0046] The display module is also used to display information such as the current check-in task, the number of check-in points, the total number of check-in points, and the task completion progress.

[0047] The induction check-in module is located inside the check-in sensing area of ​​the portable housing 11 and is electrically connected to the main control module 12. It is used to cooperate with the wireless beacon base stations at each location to complete the check-in identification at the location.

[0048] The induction check-in module is a near-field sensing and recognition module, employing either an NFC near-field communication module or a low-power Bluetooth near-field sensing module. When the handheld navigation terminal 1 approaches the wireless beacon base station at the target location to a preset distance (0.1 to 1 meter), the induction check-in module completes sensing matching with the wireless beacon base station, reads the base station's location ID information, and realizes check-in recognition at the location.

[0049] After successful attendance recognition, the main control module 12 records the attendance information (location ID, attendance time), uploads it to the backend gateway management system through the wireless communication module, triggers the vibration feedback module to provide tactile prompts, and updates the screen status of the display module.

[0050] The vibration feedback module is fixedly installed in the cavity inside the portable housing 11 and is electrically connected to the main control module 12. It is used to provide tactile prompts when the check-in is successful, the target location is approached, or the task is updated.

[0051] The vibration feedback module is a miniature vibration motor, employing either a flat vibration motor or a linear resonant motor. When the check-in is successfully recognized, the vibration feedback module generates a short vibration lasting 200ms to 500ms. When the handheld navigation terminal 1 approaches the target location to a preset distance (1 to 3 meters), the vibration feedback module generates intermittent vibration alerts, with the vibration frequency increasing as the distance decreases. When the task is updated, the vibration feedback module generates a vibration sequence with a specific pattern.

[0052] The power supply module 13 is fixedly installed in the cavity inside the portable housing 11 and is electrically connected to the main control module 12, the wireless communication module, the display module, the card-taking module and the vibration feedback module, and is used to supply power to each functional module.

[0053] The power supply module 13 includes a rechargeable battery and a power management unit. The rechargeable battery is a rechargeable lithium-ion battery or a lithium polymer battery with a capacity of 1000mAh to 5000mAh. The power management unit is electrically connected to the rechargeable battery and is used to manage the charging and discharging process of the rechargeable battery and provide the operating voltage required by each functional module.

[0054] The portable housing 11 is equipped with a charging port, which is a USB Type-C interface that is electrically connected to the power management unit and used to connect to an external power source to charge the rechargeable battery.

[0055] The complete workflow of the park visual indoor navigation terminal system in this embodiment is as follows: Wireless beacon base stations are installed at various visitor points and passageway nodes within the park. Each base station continuously broadcasts its location ID and signal information, achieving full signal coverage. The backend gateway management system configures the check-in task data for each location, including location name, task description, check-in order, and reward rules. The ID of each wireless beacon base station is bound one-to-one with the location data in the backend management system.

[0056] The user powers on the handheld navigation terminal 1. The wireless communication module scans for signals from surrounding wireless beacon base stations, and the main control module 12 calculates the initial position based on the received base station signals. The display module shows the park map and the current location. The main control module 12 requests the current park check-in task data from the backend gateway management system via the wireless communication module, and the backend gateway management system sends the task list to the handheld navigation terminal 1.

[0057] After the user obtains the list of check-in tasks for the current park through the handheld navigation terminal 1, the display module shows the distribution of task points, check-in routes, and task descriptions. The user can start playing according to the displayed directional guidance of the target points. When there are multiple target points, the main control module 12 sorts them from nearest to farthest and calculates the direction and distance of each target point in turn. The display module simultaneously displays the directional guidance of the nearest multiple target points.

[0058] When the user's handheld terminal moves within the park, the wireless communication module continuously scans for signals from surrounding wireless beacon base stations. The positioning calculation unit of the main control module 12 performs fusion positioning calculation based on the signal strength and ranging information of multiple base stations, and updates the current position of the handheld navigation terminal 1 in real time.

[0059] The navigation guidance unit compares the real-time location with preset target point data to calculate the direction and distance of the target point relative to the current location. The display module illuminates zones based on the direction and distance information—the direction of the target point corresponds to the illuminated zone, and the distance is indicated by brightness or color depth, providing users with intuitive visual direction guidance.

[0060] When the handheld navigation terminal 1 approaches the target location to a preset distance (1 to 3 meters), the vibration feedback module generates intermittent vibration prompts. The vibration frequency increases as the distance decreases, prompting the user that they are approaching the target location.

[0061] When the handheld navigation terminal 1 approaches the target location to a preset distance (0.1 to 1 meter), the sensor check-in module completes sensor matching with the wireless beacon base station of the target location, reads the location ID information of the base station, and realizes the check-in recognition of the location.

[0062] After successful check-in recognition, the main control module 12 records the check-in information, including the location ID and check-in time, and uploads it to the backend gateway management system via the wireless communication module. Simultaneously, the vibration feedback module generates short vibrations lasting 200ms to 500ms to provide tactile feedback, and the display module updates the screen status, showing the successful check-in information and the location guidance for the next target location. The backend gateway management system synchronously updates the check-in record of this terminal.

[0063] After users complete all checkpoints, the display module shows the task completion interface, displaying the number of checkpoints, time taken, and reward information. The backend gateway management system synchronously updates the user's complete check-in record and generates a play data report. Park operators can view check-in statistics, user play paths, and task completion rates for each checkpoint through the backend gateway management system, which can be used to optimize checkpoint layout and task design.

[0064] The backend gateway management system continuously collects check-in records and location information uploaded by each handheld navigation terminal 1, generating multi-dimensional operational data reports, including rankings of check-in popularity at each location, average user playtime, task completion rate, and user movement trajectory heatmaps. Based on this data, park operators can make refined operational decisions, such as adjusting the distribution of check-ins, optimizing task difficulty, and planning targeted promotional activities.

[0065] In different communication version embodiments, the overall hardware structure is completely identical: Bluetooth 6.0 High-Precision Implementation Example: The wireless communication module is equipped with a Bluetooth 6.0 module, which can achieve high-precision channel ranging, meet the needs of centimeter-level indoor positioning, and is suitable for fine indoor navigation scenarios, such as museum exhibit-level guidance and precise push notifications for shopping mall brand stores.

[0066] Bluetooth 5.4 High-Capacity Networking Example: The wireless communication module is equipped with a Bluetooth 5.4 module, which can realize PAWR concurrent networking, support the simultaneous connection of a large number of beacons, and is suitable for large-scale park full coverage and multi-person simultaneous play scenarios, meeting the needs of a large number of tourists using it at the same time during peak holiday periods.

[0067] StarSpark Communication Upgrade Example: The wireless communication module is equipped with the StarSpark Communication module. The installation structure, circuit interface, and overall terminal functions remain completely unchanged. It can achieve navigation effects with lower latency and more terminals synchronized, and is adapted to the future evolution of communication technology.

[0068] Ultra-wideband communication example: The wireless communication module is equipped with an ultra-wideband communication module, which can also realize high-precision channel ranging and positioning functions. The module installation structure, circuit interface, and functional logic are completely consistent with the Bluetooth module, and can be directly interchanged and installed without modifying the overall structure or re-molding.

[0069] In the four embodiments described above, the overall structure, installation location, circuit connection, and functional logic remain completely unchanged after module replacement, and the hardware is universally interchangeable, realizing a truly multi-protocol universal adaptation architecture.

[0070] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made to the above structure of the present invention based on the above content of the present invention, in accordance with ordinary technical knowledge and common practice in the field, without departing from the basic technical idea of ​​the present invention, shall fall within the scope of protection of the present invention.
