Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrared lens technology, and in particular to a three-component large field-of-view infrared scanning lens. Background Technology
[0002] The main positioning method of existing self-guided tour equipment is RFID positioning technology. RFID tags are installed around the exhibits in advance, and contactless communication and positioning are achieved through RFID readers. However, when the indoor scene is complex, Bluetooth signals are easily interfered with during the propagation process, which leads to an unstable signal attenuation model and affects the positioning accuracy.
[0003] For example, a museum guide device based on RFID electronic tags, with publication number CN212322552U, includes: cultural relics, electronic tags, fixed display screens, electronic tag readers, mobile guide devices, a back-end service module, and a wireless network module. Each electronic tag uses an immutable and unique serial identifier. The electronic tag readers include fixed readers and handheld readers. The fixed reader array is configured in the museum, and the handheld readers are placed on the mobile guide devices. The fixed readers and handheld readers exchange the information of the electronic tags they read with the back-end service module through the wireless network module. Corresponding cultural relic information can be obtained through electronic tag readers and identification. However, in an environment where a large number of tags exist at the same time, tag conflicts or signal interference may occur, leading to reading failures or data errors. Utility Model Content
[0004] Therefore, this utility model provides an infrared lens for self-guided tour devices, which can obtain more accurate positioning information, enhance the stability of the positioning system, and meet the needs of users.

The infrared lens is used for coarse positioning of the target object; the RFID reader is used for fine positioning of the target object after coarse positioning by the infrared lens; the power module provides the necessary power; the output of the infrared lens is connected to the input of the data transmission module, the output of the data transmission module is connected to the input of the data processing module, the output of the data processing module is connected to the input of the navigation system, the output of the navigation system is connected to the display screen, and the RFID reader is connected through the communication module and the control processor module. This utility model's three-component wide-field-of-view infrared scanning lens, through efficient interaction between infrared imaging and the environment, combined with the rapid response of the data transmission module, ensures real-time information acquisition and transmission. The powerful analytical capabilities of the data processing module provide the navigation system with accurate positioning and route planning. The seamless integration between the navigation system and the display module allows users to intuitively access navigation information and listen to real-time announcements via headphones, greatly enhancing the convenience and safety of the user experience. Furthermore, the power module's battery level display and the button module's operation prompts are clearly shown on the screen, simplifying the operation process and improving the system's user-friendliness. The introduction of an RFID reader further enhances the system's identification and control capabilities, expanding its application scenarios through collaboration with the communication and control modules. Overall, this system, with its high degree of integration, real-time information processing capabilities, intuitive user interface, and flexible interaction methods, delivers an efficient, intelligent, and user-friendly experience.

[0008] In one embodiment of this utility model, the output information of the buttons, power module, and speaker can all be displayed on the display screen.
[0009] In one embodiment of this utility model, the infrared lens is used to identify the coarse location of a target object within a 50m range.
[0010] In one embodiment of this utility model, the RFID reader is used for fine positioning of target objects within a range of 1-3m.
[0011] In one embodiment of this utility model, the data processing module uses Kalman filtering to process the input and output data of the infrared lens and RFID reader, and the data processing module outputs the coordinates of the target object.
[0012] In one embodiment of the present invention, the navigation system is used to generate a path to the target object, and the path traversed by the navigation system can be broadcast through a speaker.
[0013] In one embodiment of this utility model, the RFID reader is an Impinj R2000.
[0014] In one embodiment of this utility model, the power module has a battery life of 10 hours.
[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:
[0016] The three-component wide-field-of-view infrared scanning lens of this invention, through the establishment of a dual positioning system, can provide more accurate and stable positioning services for different distances and scenarios. Infrared positioning provides high-precision positioning over short distances, while RFID positioning provides reliable location information over a wide area. This also reduces the error and failure risks that may arise from using a single technology. Even if one positioning technology malfunctions, the other technology can still continue to provide positioning services, ensuring the continuity of the guided tour. Furthermore, due to its modular design, it is easy to maintain and upgrade. Users can choose to replace or upgrade some components according to actual needs without replacing the entire device. Besides museums, by replacing components, it can also be applied to other scenarios requiring guided tours. Attached Figure Description
