Description

Technical Field

[0001] The utility model belongs to the field of monitoring, and particularly relates to a multi-sensor fusion monitoring device for unmanned retail stores. Background Art

[0002] The multi-sensor fusion monitoring device for unmanned retail stores is a key technology that has emerged with the digital transformation and intelligent development of the retail industry. With the rapid development of artificial intelligence, the Internet of Things, and big data technologies, unmanned retail, as a new retail model, is rapidly popularizing globally. This model meets the growing convenience needs of consumers by reducing labor costs, improving operational efficiency, and providing 24 / 7 service. However, there are many challenges in aspects such as security management, commodity management, and customer behavior analysis in unmanned retail stores, which requires a set of efficient and reliable monitoring systems to ensure the normal operation of the stores. Traditional single-sensor monitoring systems are unable to cope with these complex requirements and have many drawbacks and limitations.

[0003] A single type of sensor is difficult to comprehensively capture various situations in the store. For example, relying solely on video monitoring may not accurately identify the movement of goods and inventory changes, while a simple weight sensor cannot distinguish the behaviors of different customers. The reliability of a single-sensor system is relatively low and is easily affected by environmental factors or equipment failures, resulting in monitoring blind spots or misjudgments. Moreover, traditional monitoring systems often lack the ability to process and analyze real-time data, unable to respond to abnormal situations in a timely manner or provide valuable insights for management decisions. In addition, existing monitoring systems have deficiencies in data integration and information fusion, making it difficult to fully utilize multi-source data to improve the accuracy and comprehensiveness of monitoring.

[0004] In terms of privacy protection, traditional systems also face challenges and it is difficult to effectively protect customer privacy while ensuring the monitoring effect. Although some existing multi-sensor systems have improved the limitations of single sensors to a certain extent, there are still many problems.

[0005] For example, the data synchronization and coordination problems between different types of sensors have not been well solved, resulting in poor information fusion effects. At the same time, the complexity of multi-sensor systems increases the difficulty of installation, maintenance, and management, raising the operating costs. In terms of data processing, existing systems often adopt a centralized architecture and face problems such as data transmission bandwidth limitations and insufficient real-time performance. In addition, existing multi-sensor systems need to be strengthened in advanced functions such as intelligent decision support, abnormal event warning, and adaptive adjustment. In terms of commodity identification and tracking, existing technologies are difficult to handle complex scenarios with a large variety of goods and dense placement.

[0006] The accuracy and depth of customer behavior analysis also need to be improved, especially in differentiating different customers and analyzing shopping intentions. Therefore, developing a monitoring system that can effectively integrate multiple sensors to achieve high-efficiency, reliability, and intelligence is of great significance for promoting the development of unmanned retail stores.

[0007] Therefore, there is an urgent need for a multi-sensor fusion monitoring device for unmanned retail stores. Summary of the Utility Model

A screw passes through the shielding plate through hole and is connected and fixed to a threaded hole on the upper part of the front end surface of the monitor body. A cushion block is provided at the connection position between the lower part of the shielding plate through hole and the monitor body. The cushion block through hole provided on the cushion block matches the shielding plate through hole. A sensor mounting plate is provided at the lower part of the front end surface of the monitor body, and two mounting positions are provided on the sensor mounting plate. A mounting bracket is provided in the middle of the lower end surface of the monitor body, and the monitor body is fixed through the mounting bracket.

[0010] Heat dissipation holes are opened on the front and rear sides of the upper end surface of the monitor body. This design optimizes the heat dissipation performance of the equipment, helps to extend the service life of the equipment and maintain stable operation, which is particularly important in the unmanned retail environment with long-term operation.

[0011] The shielding plate provided above the camera is a unique design element. It can not only protect the camera from external environmental interference but also may help to improve the camera effect and reduce problems such as light reflection or occlusion. The fixing method of the shielding plate is also very ingenious. It is connected to the monitor body through the shielding plate through hole in the middle of the rear side and screws. This design is both firm and convenient for installation and disassembly.

[0012] It is particularly noteworthy that a cushion block is provided at the connection position between the lower part of the through hole of the shielding plate and the monitor body. This detailed design may help to adjust the angle or height of the shielding plate, improving the flexibility and accuracy of installation. The design of the sensor mounting plate is also a major highlight. It is located at the lower part of the front end face of the monitor body and provides two mounting positions. This design enables the device to integrate multiple sensors to achieve multi-sensor fusion monitoring, greatly enhancing the comprehensiveness and accuracy of monitoring, which is particularly important in a complex unmanned retail environment.

[0015] As a preferred embodiment, a baffle is inclinedly arranged on the rear end face of the monitor body. The lower part of the baffle is in an arc structure, and the left and right sides of the upper part of the baffle are symmetrically inclined. The upper end face of the upper part of the baffle is parallel to the horizontal plane.

[0016] As a preferred embodiment, a protection plate is arranged on the front end face of the monitor body. The structure of the protection plate is the same as that of the baffle. A through hole is provided in the middle of the protection plate, and the diameter of the through hole is larger than the diameter of the lens assembly adapted to the camera.

[0017] As a preferred embodiment, the mounting positions on the sensor mounting plate are symmetrically arranged. Specific sensors are mounted on the mounting positions, and the sensor data lines are connected to the monitor body.

[0018] After adopting the above technical solutions, the beneficial effects of the utility model are as follows: The heat dissipation hole design on the monitor body significantly improves the heat dissipation efficiency of the device, extends the service life of the device, and ensures long-term stable operation, which is crucial for 24-hour operating unmanned retail stores.

[0019] The shielding plate design above the camera not only protects the camera, but also optimizes the imaging quality, reduces environmental light interference, and improves the clarity and accuracy of monitoring. The adjustable design of the shielding plate increases the installation flexibility, enabling the camera to better adapt to different store layouts and monitoring requirements. The design of the sensor mounting plate realizes the integration of multiple sensors, greatly enhancing the comprehensiveness and precision of monitoring.

[0020] The fusion of multiple sensors enables the device to more comprehensively monitor the store environment, improves the detection ability of abnormal situations, and enhances the security of the store. The versatility and scalability of this design enable it to adapt to different types and scales of unmanned retail stores, improving the market adaptability of the product. Generally speaking, this innovative design has brought significant beneficial effects in improving the monitoring effect, enhancing security, optimizing store management, and reducing operating costs, providing strong technical support for the intelligent and efficient operation of unmanned retail stores.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] Embodiment:

[0026] As Figure 1 shown, the multi-sensor fusion monitoring device for unmanned retail stores includes heat dissipation holes 11 opened on the front and rear sides of the upper end face of the monitor body 1. A camera 12 is provided on the front end face of the monitor body 1. A shielding plate 2 is provided above the camera 12. A shielding plate through hole 21 is provided at the rear side of the middle part of the shielding plate 2. A screw 22 passes through the shielding plate through hole 21 and is connected and fixed to the threaded hole on the upper part of the front end face of the monitor body 1. A cushion block 3 is provided at the connection position between the lower part of the shielding plate through hole 21 and the monitor body 1. A cushion block through hole 31 provided on the cushion block 3 matches the shielding plate through hole 21. A sensor mounting plate 4 is provided at the lower part of the front end face of the monitor body 1. Two mounting positions 41 are provided on the sensor mounting plate 4. A mounting bracket 5 is provided at the middle part of the lower end face of the monitor body 1. The monitor body 1 is fixed through the mounting bracket 5.

[0027] The working principle and operation steps of this multi-sensor fusion monitoring device for unmanned retail stores are as follows: The monitor body, as the core of the entire device, has heat dissipation holes opened on the front and rear sides of its upper end face for heat dissipation, ensuring that the device can maintain a normal operating temperature during long-term operation. The camera provided on the front end face of the monitor body is a key component of the entire monitoring system, used to capture real-time images inside the store. The shielding plate provided above the camera plays a role of protection and shielding, preventing direct external light from shining on the camera and affecting the image quality.

[0028] The shielding plate is connected and fixed to the threaded hole on the upper part of the front end face of the monitor body through screws. This design not only ensures the stability of the shielding plate but also facilitates later maintenance and replacement. The cushion block provided at the connection position between the lower part of the shielding plate through hole and the monitor body plays a role of buffering and adjustment, and can finely adjust the angle and position of the shielding plate to obtain the best shielding effect. The sensor mounting plate provided at the lower part of the front end face of the monitor body provides mounting positions for other types of sensors. This design enables the entire monitoring device to integrate multiple sensors and achieve multi-dimensional monitoring and data collection. The two mounting positions provided on the sensor mounting plate increase the expandability of the device, and different types of sensors can be installed according to actual needs. The mounting bracket provided at the middle part of the lower end face of the monitor body is used to fix the entire device in a suitable position, ensuring the stability of the monitoring perspective and maximizing the coverage range.

[0029] There are several important reasons for this design and operation method:

[0030] Multi-functional integration: By integrating a camera and other sensors in one device, multi-dimensional monitoring and data collection are achieved, enabling a comprehensive understanding of the situation inside the store, including video monitoring, environmental parameter monitoring, etc. Modular design: The design of the sensor mounting plate and multiple mounting positions makes the device have good scalability and adaptability, and different sensors can be flexibly configured according to the needs of different stores. Heat dissipation consideration: The heat dissipation holes on the upper end face ensure that the device can maintain a normal operating temperature during long-term operation, improving the reliability and service life of the device.

[0031] Image quality optimization: The design of the shielding plate effectively prevents external light from interfering with the camera, improving the quality and clarity of the monitoring images. Installation flexibility: The mounting bracket on the lower end face enables the device to be flexibly installed in different positions, such as on the ceiling, wall, etc., to obtain the best monitoring effect. 6. Maintenance convenience: The detachable design of the shielding plate and the sensor mounting plate facilitates later maintenance and upgrade, reducing the maintenance cost. Aesthetic and practical: The overall design takes into account both functionality and appearance, enabling the device to blend well into the store environment without affecting the overall aesthetics of the store.

[0032] Cost-effectiveness: Through the integrated design, the need for installing multiple devices separately is reduced, lowering the overall installation and maintenance costs. Data fusion: The design of multiple sensors provides a basis for subsequent data analysis and fusion, facilitating more intelligent store management and decision-making support. Safety consideration: The design of the shielding plate not only optimizes the image quality but also protects the camera to a certain extent, enhancing the safety and durability of the device. The design of this multi-sensor fusion monitoring device for unmanned retail stores fully considers functionality, practicality, maintainability, and scalability, providing strong hardware support for the intelligent management of unmanned retail stores.

[0033] There are at least 5 mounting hole positions 13 arranged in an array around the center point of the front end face of the camera 12. The mounting hole positions 13 are divided into outer ring hole positions and inner ring hole positions, and the corresponding specifications of the camera lens components are adapted through the two types of hole positions.

[0034] The design of arranging at least 5 mounting hole positions in an array around the center point of the front end face of the camera greatly improves the compatibility and adaptability of the camera lens components. Traditional camera designs usually only provide fixed mounting hole positions, restricting the use of different specifications of lenses. However, this innovative design provides multiple mounting hole positions, enabling a single camera body to be adapted to a variety of different specifications and models of lens components, greatly increasing the flexibility and versatility of the device.

[0035] The design of dividing the mounting hole positions into outer ring hole positions and inner ring hole positions ingeniously solves the installation problems of lenses of different sizes. The outer ring hole positions can be used to mount lenses with a larger diameter, while the inner ring hole positions are suitable for mounting lenses with a smaller diameter. This double-ring design not only expands the range of lenses that can be used by the camera but also ensures the stability and accuracy during the installation of lenses of different sizes.

[0036] Compared with the prior art, this design greatly reduces the possibility of replacing the entire camera device due to lens replacement, thereby reducing the costs of equipment update and maintenance. In addition, this design also reserves installation space for new types of lenses that may appear in the future, enhancing the future compatibility of the device. In practical applications, this design allows users to quickly replace different types of lenses according to different monitoring requirements (such as wide-angle monitoring, long-distance monitoring, etc.) without replacing the entire camera device, greatly improving the practicality and economy of the device.

[0037] This design also provides greater design space for camera manufacturers, enabling them to develop more diverse and professional lens products, and promoting the technological progress of the entire monitoring equipment industry. From the production perspective, this design can also simplify the camera production line. One type of camera body can be adapted to multiple lenses, reducing the production requirements for different models of cameras, which is beneficial to large-scale production and cost control.

[0038] A baffle 6 is inclinedly arranged on the rear end surface of the monitor body 1. The lower part of the baffle 6 is of an arc structure, and the upper part of the baffle 6 is symmetrically inclined on the left and right sides. The upper end surface of the upper part of the baffle 6 is parallel to the horizontal plane.

[0039] The design of inclinedly arranging the baffle on the rear end surface of the monitor body is an important improvement to the structure of traditional monitoring equipment. Traditional monitoring equipment usually adopts a flat or simple arc-shaped rear cover, while this inclined baffle design not only increases the aesthetic appearance of the equipment but also has multiple functional advantages. The inclined design can effectively reduce the reflection and glare on the back of the equipment, improving the clarity and quality of the monitoring image.

[0040] The design of adopting an arc structure for the lower part of the baffle is a clever innovation. This arc structure can reduce the gap between the equipment and the installation surface, reducing the possibility of dust and debris accumulation, and at the same time increasing the stability of the equipment. The arc structure can also reduce the friction between the equipment and the surrounding environment, reducing wear and extending the service life of the equipment.

[0041] The design of symmetrically inclined arrangement on the left and right sides of the upper part of the baffle not only increases the aesthetic appearance of the equipment but may also have a guiding effect, helping with the heat dissipation and dust prevention of the equipment. This design can make the air flow naturally, improving the heat dissipation efficiency of the equipment and extending the service life of the equipment.

[0042] The design that the upper end face of the upper part of the baffle is parallel to the horizontal plane not only ensures the stability of the device but also provides possibilities for possible additional functions (such as placing small items or connecting other devices). Compared with the prior art, this design comprehensively considers functionality, aesthetics, and practicality. It not only solves the problems of easy dust accumulation on the back of traditional monitoring devices, low heat dissipation efficiency, and unstable installation but also improves the overall performance of the device through a clever structural design.

[0043] This design may also reduce production costs because the arc structure and inclined plane can be formed by an integrated mold, reducing the number of parts and assembly processes. From the perspective of user experience, this design makes the device more beautiful, easier to integrate into various environments, and also facilitates cleaning and maintenance.

[0044] A protection plate 14 is provided on the front end face of the monitor body 1. The structure of the protection plate 14 is the same as that of the baffle 6. A through hole is provided in the middle of the protection plate 14, and the diameter of the through hole is larger than the diameter of the lens assembly adapted to the camera 12.

[0045] The practice of providing a protection plate on the front end face of the monitor body itself is an important improvement to the design of traditional monitoring devices. Traditional monitoring devices usually expose the camera directly to the external environment, making it vulnerable to physical damage and environmental factors. This design greatly improves the safety and durability of the camera by adding a protection plate.

[0046] The structure of the protection plate is consistent with that of the baffle at the back end. This design not only maintains the integrity and aesthetics of the device visually but may also play a similar role functionally, such as reducing reflection and guiding air flow. This design concept of echoing before and after is quite innovative in the field of monitoring devices.

[0047] The design of providing a through hole in the middle of the protection plate protects the camera without affecting its normal operation. The diameter of the through hole is larger than the diameter of the lens assembly adapted to the camera. This detailed design ensures that the field of view of the camera is not blocked and reserves enough space for lenses of different sizes, increasing the compatibility and flexibility of the device.

[0048] Compared with the prior art, this design solves the following problems: improves the protection level of the camera and reduces the risk of device damage caused by external environmental factors; enhances the overall aesthetics of the device and makes it easier to integrate into various application environments; may improve the heat dissipation performance of the device by forming an air circulation channel through the design of the front and back plates; increases the versatility of the device, and the protection plate may provide an installation position for additional functions (such as installing fill lights, infrared sensors, etc.);

[0049] It improves the convenience of equipment cleaning and maintenance. The protection board can effectively block dust and debris from entering the interior of the equipment. This design may also bring advantages in production and cost. The consistent front and rear board structures mean that the same mold can be used, simplifying the production process and reducing production costs. From the perspective of user experience, this design makes the equipment more durable, reduces the maintenance frequency, and at the same time maintains a good appearance and functionality.

[0050] The mounting positions 41 on the sensor mounting board 4 are symmetrically arranged. Specific sensors are mounted on the mounting positions 41, and the sensor data lines are connected to the monitor body 1.

[0051] The design of symmetrically arranging the mounting positions on the sensor mounting board is an important improvement to the structure of traditional monitoring equipment. Traditional monitoring equipment usually only integrates a single camera function and lacks the integration ability of other types of sensors. This innovative design enables the monitoring equipment to flexibly integrate a variety of different types of sensors by providing a dedicated sensor mounting board and symmetric mounting positions, greatly expanding the functionality and adaptability of the equipment. The symmetrically arranged mounting positions not only ensure the balance and aesthetics of the equipment but also provide a unified mounting standard for different types of sensors, simplifying the installation and maintenance process.

[0052] This design allows users to select and install specific sensors according to specific needs, such as temperature sensors, humidity sensors, infrared sensors, smoke sensors, etc., so as to achieve multi-dimensional environmental monitoring and data collection. This flexibility is rare in the existing technology, which enables the same equipment to adapt to different application scenarios and greatly improves the versatility and cost performance of the equipment.

[0053] The design of directly connecting the sensor data line to the monitor body simplifies the complexity of the system, reduces the need for external wiring, and improves the stability and reliability of the system. This integrated design not only simplifies the installation process but also reduces the failure rate and maintenance cost.

[0054] Compared with the prior art, this design solves the following problems: it improves the versatility of the monitoring device, transforming it from a single video monitoring device into an integrated environmental monitoring system; it enhances the scalability and adaptability of the device, enabling it to be flexibly configured according to different application requirements; it simplifies the system structure, reduces external connections and interfaces, and improves the overall stability of the system; by integrating multiple sensors, it realizes the comprehensive collection and analysis of data, providing more comprehensive information support for intelligent decision-making; it reduces the cost of the overall system because users can choose to install necessary sensors according to actual needs without having to purchase multiple independent devices. From the production perspective, this design can also simplify the production line. One monitor body can be adapted to multiple sensor combinations, reducing the production requirements for different models of devices, which is beneficial to large-scale production and cost control. From the user experience perspective, this design provides a higher degree of customization. Users can choose and replace sensors according to actual needs, improving the practicality and cost performance of the device.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
