Description

Technical Field

[0001] This utility model relates to computing terminals, specifically to an integrated structure of a multi-source sensing terminal for scenic areas. Background Technology

[0002] Current on-site deployments for visitor flow and environmental monitoring in scenic areas typically employ a split-system approach: visitor counting sensors, environmental sensors, edge gateways / communication boxes, power supply components, and mounting brackets are installed separately, relying on on-site cabling for power supply and data connectivity. This type of solution generally suffers from the following problems during engineering implementation:

[0003] Firstly, the large number of devices, fixed points, wiring, and multiple waterproofing treatments lead to complex construction and high deployment costs.

[0004] Secondly, when any sensor or component fails, it is often necessary to disassemble multiple housings or disconnect multiple connections. Maintenance, positioning, and replacement are time-consuming, resulting in long downtime and potential data interruptions.

[0005] Third, when outdoor power supply and network conditions are unstable, split-type connections are more prone to loose interfaces, poor contact, or power outages, affecting data continuity and reliability.

[0006] Fourth, it is difficult to balance "sealing and waterproofing" and "heat dissipation and cooling" in outdoor enclosures. Strengthening the seal can easily cause the temperature to rise, while strengthening the heat dissipation increases the risk of water ingress and condensation.

[0007] Fifth, the on-site installation carriers are diverse (light poles, guardrails, columns, etc.), and traditional equipment often requires replacement of different brackets or secondary processing, resulting in poor project replicability. Utility Model Content

[0008] In view of the above-mentioned defects or deficiencies in the existing technology, it is desirable to provide an integrated structure for a multi-source sensing terminal in scenic areas.

[0009] According to the technical solution provided in the embodiments of this application, an integrated structure of a multi-source sensing terminal for scenic areas includes:

[0010] The housing assembly has an internally isolated upper and lower cavity, the upper cavity being the sensor window area and the lower cavity being the power supply and computing area;

[0011] The sensor compartment assembly, which is located in the upper cavity, is used to install passenger flow counting sensors and environmental sensors, and is connected to the outer shell assembly by a pull-out or quick-release method.

[0012] An edge computing and communication component, which is disposed in the lower cavity and electrically connected to the sensor compartment assembly, is used to process sensor data and perform external communication.

[0013] A power supply component, which is disposed in the lower cavity, includes a solar panel interface and a battery compartment, and is used to supply power to the sensor compartment component and the edge computing and communication component;

[0014] A heat dissipation and waterproofing component includes a heat-conducting plate, fins, and a rain cover. The heat-conducting plate is used to conduct heat generated by the heat source in the lower cavity to the fins, and the rain cover is disposed above the fins.

[0015] The mounting and fixing components include clamp mounting structures and foot mounting structures, which are used to adapt to different mounting carriers.

[0016] In this solution, a sealed isolation structure and a waterproof wiring structure are provided between the upper cavity and the lower cavity, and the connecting cable between the sensor cabin assembly and the edge computing and communication assembly passes through the waterproof wiring structure.

[0017] In this solution, a guide structure, a locking structure, and a limiting structure are provided between the sensor cabin assembly and the outer shell assembly to achieve assembly guidance, working state locking, and stroke limitation.

[0018] In this design, the battery compartment is equipped with a guide structure to prevent misinsertion.

[0019] In this solution, the rain cover and the sealing structure of the outer shell assembly cooperate to form a synergistic structure for waterproofing and heat dissipation.

[0020] In this solution, the clamp mounting structure and the foot mounting structure are either integrated or switchable, and are used to connect to the outer shell assembly.

[0021] In this solution, the guide structure is a slide rail, and the locking structure is a snap-fit ​​or a rotary lock.

[0022] In this solution, the heat-conducting sheet is in contact with the main heat-generating component of the edge computing and communication assembly.

[0023] In this solution, the sensor cabin assembly integrates a camera and at least one environmental sensor, which includes one or more of a temperature and humidity sensor, an air quality sensor, and a noise sensor.

[0024] In summary, the beneficial effects of this application are as follows:

[0025] Integrated design reduces the number of devices and wiring complexity, improving on-site installation efficiency; the quick-release / pull-out structure of the sensor compartment reduces the scope of maintenance and disassembly, shortening downtime and thus reducing the risk of data loss; the compartmentalized sealed isolation and waterproof wiring structure reduces the probability of water ingress causing failure, improving outdoor operational reliability; the combined structure of heat-conducting sheet-fin-rainproof cover alleviates the contradiction between "waterproofing and heat dissipation," improving outdoor adaptability; the dual-purpose clamp / foot mounting structure enhances cross-scenario adaptability and project replication capabilities.

[0037] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] like Figures 1 to 3 As shown in the figure, this embodiment provides an integrated structure for a multi-source sensing terminal in a scenic area. Its core design concept lies in solving the engineering challenges of outdoor deployment through structural integration and modularization. The terminal mainly includes a shell assembly 1, a sensor compartment assembly 2, an edge computing and communication assembly 3, a power supply assembly 4, a heat dissipation and waterproofing assembly 5, and a mounting and fixing assembly 6.

[0040] 1. Housing assembly 1

[0041] The outer casing assembly 1 is the main external protective structure of the entire terminal, injection molded from high-strength, weather-resistant engineering plastics (such as PC+ABS alloy). Internally, it is strictly divided into an upper cavity 1-1 and a lower cavity 1-2 by a horizontal inner partition. The front wall of the upper cavity 1-1 is designed as a transparent acrylic window, serving as the sensor window area, allowing unobstructed transmission of infrared, laser, and other signals. The lower cavity 1-2 is a sealed power and computing area. The sealing isolation structure 1-3 between the upper and lower cavities consists of the inner partition and its surrounding annular silicone sealing ring, ensuring airtightness and watertightness between the cavities. At specific locations on the sealing isolation structure 1-3, one or more cable routing holes are provided, each equipped with a waterproof cable routing structure 1-4. In this example, an IP67-rated waterproof cable gland (waterproof cable connector) is used to secure and seal the cable introduced from the sensor compartment assembly 2 into the lower cavity.

[0042] 2. Sensor Cabin Component 2

[0043] The sensor compartment assembly 2 is a separate modular drawer connected to the outer shell assembly 1 via a pull-out mechanism. Its frame features a guide structure 2-1, in this example, two metal slide rails that match corresponding grooves on the inner side of the upper cavity of the outer shell. When fully pushed into the working position, the locking structure 2-2 (a spring-loaded push-button or bolt-locking structure) automatically engages, locking the compartment. The limiting structure 2-3 is a physical stop at the end of the slide rails to prevent the compartment from being excessively pulled out and falling off.

[0044] The cabin integrates multiple sensing sensors:

[0045] Passenger Flow Counting Sensor: Employs a binocular stereo vision sensor (model example: Intel RealSense D435i). Its working principle involves using two infrared cameras to simulate human eye parallax, acquiring depth information of objects within the field of view. Combined with a built-in AI algorithm, it can detect, track, and count passing tourists in real time, and distinguish between entry and exit directions. The sensor is installed inside the cabin, with its lens facing the transparent window of the outer shell.

[0046] The parameters of this passenger flow counting sensor (Intel RealSense D435i) are as follows:

[0047] Depth performance: Utilizing active stereo vision technology, it can effectively measure distances of 0.3m-3m (official data), and some tests show that this can be extended to 0.2m-10m.

[0048] Supported resolutions: up to 1280×720@30fps (depth) / 1920×1080@30fps (RGB), with support for synchronous output.

[0049] Sensor configuration: Integrated Bosch BMI055 6-axis IMU module (3-axis accelerometer + 3-axis gyroscope).

[0050] Physical characteristics: Dimensions 90×25×25mm (camera module), USB 3.0 interface.

[0051] Environmental adaptability: It has a built-in infrared projector to assist in weak texture scenes, but it relies on a stereo algorithm.

[0052] Environmental sensor set: Integrated on a small circuit board, including:

[0053] Temperature and humidity sensor (model example: Sensirion SHT40): Based on CMOSens® technology, it measures humidity through a capacitive polymer sensor and temperature through a bandgap temperature sensor, outputting a digital signal.

[0054] The Sensirion SHT40 is a digital temperature and humidity sensor based on CMOSens® technology, known for its high accuracy, low power consumption and compact design, making it suitable for a variety of environmental monitoring applications.

[0055] Core Features

[0056] Accuracy specifications: Typical humidity accuracy is ±1.8% RH (0%–80% RH at 25°C), temperature accuracy is ±0.2°C (0°C–60°C), and some sources mention a maximum error of ±3.5% RH.

[0057] Power consumption and voltage: The operating voltage range is 1.08 V to 3.6 V, and the average current is as low as 0.4 µA, making it suitable for battery-powered devices.

[0058] Size and Packaging: The package size is 1.5 mm × 1.5 mm × 0.5 mm (typical), using a DFN package, supporting tape and reel packaging and SMD processes, facilitating integration into compact designs.

[0059] Interface and Reliability: Provides an I²C digital interface, supports CRC checksum, is JEDEC JESD47 certified, and has electromagnetic interference immunity.

[0060] Air quality sensor (model example: Sensirion SGP40): Based on metal oxide (MOX) technology, it measures the volatile organic compound (VOC) index by detecting changes in sensor resistance caused by gas molecules.

[0061] The Sensirion SGP40 is a digital volatile organic compound (VOC) sensor based on metal oxide (MOX) technology, designed specifically for indoor air quality monitoring and control applications.

[0062] Technical basis: Sensirion’s CMOSens® technology integrates a complete sensor system (including digital I²C interface, temperature-controlled hotplate and humidity compensation) onto a single chip.

[0063] Output signal: Provides raw digital signal (16-bit) and processed VOC index (0–500 VOC Index), which directly reflects the degree of change in indoor air quality relative to typical environments.

[0064] Key parameters:

[0065] Measurement range: 0–1000 ppm (ethanol equivalent).

[0066] Response time: τ63% < 10 seconds.

[0067] Supply voltage: 1.7–3.6 V, typical current consumption is 2.6 mA (at 3.3 V).

[0068] Package size: 2.44 × 2.44 × 0.85 mm, suitable for miniaturized devices.

[0069] Power consumption optimization: Through multi-pixel and multi-heatplate design, it supports individual component-level control, significantly reducing power consumption, making it suitable for battery-powered devices (such as portable air quality monitors).

[0070] Working principle and algorithm

[0071] The SGP40 incorporates Sensirion's advanced VOC algorithm (implemented via the VOC Index driver package) to convert raw sensor signals into a quantifiable air quality index. This algorithm effectively compensates for the effects of humidity and maintains signal stability over long periods, ensuring high reliability even in environments with siloxane pollution.

[0072] Noise sensor (model example: ChipMingMing MEMS microphone module): It uses a high-precision MEMS microphone to collect sound signals. The internal circuit converts the sound pressure signal into a voltage signal, and then converts it into a digital noise decibel value through an ADC.

[0073] All sensor data are transmitted through a single bundled cable, which is connected to the lower cavity via the glands of the waterproof wiring structure 1-4.

[0074] 3. Edge computing and communication components 3

[0075] The edge computing and communication component 3 is fixedly mounted on the main mounting plate of the lower cavity 1-2. Its core is an edge computing unit (e.g., an embedded core board based on NVIDIA Jetson Nano or Rockchip RK3568), responsible for running passenger flow statistics algorithms, environmental data aggregation, and preprocessing programs. This component also integrates a communication module, in this example including a 4G Cat.1 DTU (data transmission unit) and a Wi-Fi / Bluetooth module, used to upload processed structured data (such as minute-level passenger flow, temperature and humidity, AQI, and noise level) to the scenic area management cloud platform via a wireless network. The component is connected to the sensor compartment component 2 and the power supply component 4 via internal cabling.

[0076] 4. Power supply component 4

[0077] The power supply component 4 is also located in the lower cavity 1-2. It includes:

[0078] Solar panel interface 4-1: A waterproof aviation connector for connecting a 60W flexible solar panel to power the system and charge the battery during the day.

[0079] Battery compartment 4-2: A specially designed slot for holding a 12V / 20Ah lithium iron phosphate battery. Battery compartment 4-2 features an anti-misinsertion guide structure 4-3, namely an asymmetrical slot and battery plug design, ensuring that the battery can only be inserted in one correct orientation, preventing circuit damage caused by reverse connection.

[0080] The power management system (BMS) board is integrated near the warehouse and is responsible for solar charging management, battery charging and discharging protection, and providing a stable 5V and 12V DC power supply for the entire terminal.

[0081] 5. Heat dissipation and waterproofing components

[0082] To address the heat generated by the edge computing units within the lower cavities 1-2 during operation, the heat dissipation and waterproofing components 5 employ a collaborative design:

[0083] Heatsink 5-1: A high thermal conductivity aluminum sheet, mounted close to the main chip of the edge computing unit, to conduct heat laterally.

[0084] Fin 5-2: An integrated array of aluminum heat dissipation fins connected to the heat-conducting plate 5-1 and extending to the outside of the outer side wall of the casing, increasing the contact area with the air and utilizing natural convection for heat dissipation.

[0085] Rain Cover 5-3: An integrally molded, sloping plastic cover located directly above the fin 5-2, with its edges extending beyond the outer edge of the fin. This effectively prevents rainwater and fallen leaves from falling vertically into the gaps between the fins while maintaining airflow around the fins. This structure, together with the sealing process of the outer shell, achieves an IP65 protection rating.

[0086] 6. Install and fix the components 6

[0087] To adapt to different installation scenarios, the mounting and fixing component 6 is designed with a dual-purpose structure:

[0088] 6-1 Installation structure of clamp: A set of stainless steel clamps with adjustable diameter (Φ50mm-Φ120mm), which can be quickly connected to the interface reserved at the bottom of the shell through its back plate, suitable for light poles and columns.

[0089] Foot mounting structure 6-2: The bottom of the outer casing has four lugs with expansion bolt holes. When the terminal needs to be installed on a wall or guardrail, it can be directly fixed with bolts.

[0090] Workflow:

[0091] On-site, the installation and fixing component 6 is first selected and installed according to the installation carrier to fix the terminal. The solar panel is connected to interface 4-1. After the terminal is powered on, the power supply component 4 continuously supplies power to all components. The sensors in the sensor cabin component 2 start working, and the raw data collected is transmitted to the edge computing and communication component 3 in the lower cavity through waterproof cables. The edge computing unit performs real-time analysis of the passenger flow video stream, calibrates and encapsulates the environmental data, and then periodically reports the processing results to the cloud platform through the 4G network. When a sensor needs maintenance or upgrade, the entire sensor cabin component 2 can be pulled out and replaced along the guide structure 2-1 simply by pressing the locking structure 2-2. The entire process does not require opening or touching the power and computing core components in the lower cavity 1-2, achieving rapid maintenance and minimizing the risk of data interruption.

[0092] In this solution, except for those components that are specifically specified, all other components are standard parts available on the market.

Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
