Description

Technical Field

[0001] This invention relates to the field of Cordyceps sinensis detection technology, and in particular to a portable Cordyceps sinensis identification instrument. Background Technology

[0002] Cordyceps sinensis, a traditional and precious Chinese medicinal herb, commands extremely high market value due to its unique growing environment and scarcity. This scarcity has also led to a proliferation of counterfeit and substandard products. Traditional identification of Cordyceps sinensis relies primarily on professional visual observation of its appearance (such as the length of the fungus head, the ring patterns on the insect body, color, and texture), depending on subjective experience. This method has significant drawbacks: first, the identification results are highly subjective and inconsistent, with large differences in judgment among different individuals, making standardized grading difficult; second, it has a high operational threshold, requiring professionals to perform the identification in a laboratory environment using microscopes and other equipment, which cannot meet the needs of rapid on-site identification during harvesting at the production site or in market transactions; and third, it lacks objective quantitative evidence, making it difficult to accurately classify the quality grades of Cordyceps sinensis.

[0003] With the development of artificial intelligence technology, image recognition-based intelligent identification technology has provided a new path for the detection of Cordyceps sinensis. However, existing intelligent identification devices generally suffer from problems such as large size, complex structure, and high power consumption. They usually require external power supplies and display devices, making them unsuitable for mobile scenarios such as field operations and mobile vendors carrying them. In addition, existing devices lack intelligent distance guidance mechanisms in the image acquisition stage, which can easily lead to blurred images and inaccurate feature extraction due to improper shooting distance, thus affecting the reliability of the identification results. Therefore, there is an urgent need for a portable Cordyceps sinensis identification device that integrates a lightweight structure, intelligent distance control, and efficient image processing to solve the technical problems of poor portability, low level of intelligence, and weak field applicability in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a portable Cordyceps sinensis identification instrument, which overcomes the shortcomings of existing technologies such as reliance on manual experience, bulky and inconvenient equipment, and difficulty in guaranteeing image acquisition quality.

[0005] This invention is achieved using the following technical solution: a portable Cordyceps sinensis identification instrument, characterized in that it includes a housing with an internal mounting cavity; a high-definition camera fixed to the front end of the housing for acquiring image data of Cordyceps sinensis; an infrared ranging module mounted on the front of the housing for detecting the distance between the high-definition camera and the sample to be tested; a touch screen embedded in the front of the housing for displaying images and interactive information; a main control system located inside the housing and electrically connected to the high-definition camera, the infrared ranging module, and the touch screen; and a communication system electrically connected to the main control system for data uploading and result feedback; wherein the infrared ranging module is configured to monitor the shooting distance in real time and output distance prompts on the touch screen to guide the user to acquire images through the high-definition camera at a preset distance.

[0006] Furthermore, the housing has a streamlined shape and its center of gravity is located in the lower middle part of the device, making it suitable for one-handed holding.

[0007] Furthermore, the infrared ranging module adopts time-of-flight ranging technology, with a ranging accuracy of ±2mm and a ranging range of 0.1m to 5m; the distance prompt information includes three states: too far, appropriate, and too close.

[0008] Furthermore, the high-definition camera uses an image sensor with an effective pixel count of 12 million or more, supporting high-resolution image acquisition; the optical axis of the high-definition camera is aligned with the length direction of the housing.

[0009] Furthermore, the main control system adopts a dual-core architecture, including a high-performance computing module and a microcontroller unit; the high-performance computing module is responsible for running the AI ​​image recognition algorithm, and the microcontroller unit is responsible for sensor data acquisition and peripheral control; the two cores are connected via a high-speed bus.

[0010] Furthermore, it also includes operation buttons, which are located on the side of the housing and electrically connected to the main control system; the operation buttons include a camera shortcut key, used to trigger the high-definition camera to capture images when the distance is appropriate.

[0011] Furthermore, the identification device supports handheld mode and fully automatic mode; in handheld mode, 4 images are acquired per batch; in fully automatic mode, the device connects to the matching fully automatic identification container via magnetic contacts or Bluetooth, and automatically acquires 16 images per batch.

[0012] Furthermore, it also includes a power supply system, which uses a rechargeable lithium battery pack with a nominal voltage of 12V and a capacity of 9800mAh. The device's battery life is no less than 12 hours when fully charged.

[0013] Furthermore, the communication system integrates a mobile communication module, supporting 4G / 5G mobile communication and WiFi wireless network; a SIM card slot is provided on the side of the housing, which is electrically connected to the communication system for installing a SIM card to realize mobile network communication; the communication system is used to upload the collected image data to the cloud server and receive the authentication result returned by the cloud server.

[0014] The portable Cordyceps sinensis identification instrument of the present invention has the following beneficial effects: The shell features a compact, streamlined design with a center of gravity located slightly below the center, allowing for one-handed operation. It is lightweight and compact, making it easy to carry to complex environments such as field production sites and trading venues, without relying on a fixed laboratory location.

[0015] Intelligent distance guidance ensures controllable image quality: The infrared TOF ranging module monitors the shooting distance in real time and dynamically displays "far / suitable / near" prompts on the touch screen, forcing users to capture images within the optimal distance range. This effectively avoids image blurring and feature distortion caused by improper distance, providing high-quality input data for subsequent AI identification.

[0016] Dual-core architecture, balancing computing power and energy efficiency: The dual-core main control system adopts a high-performance computing module and a microcontroller. The former focuses on the operation of AI image recognition algorithms, while the latter is responsible for real-time task scheduling and low power consumption management, which not only ensures the processing power of the identification algorithm, but also optimizes the overall energy efficiency ratio.

[0017] Long battery life and extended working time: With a built-in 9800mAh high-capacity lithium battery and a low-power design, it can work continuously for more than 12 hours on a full charge, meeting the needs of high-intensity on-site identification throughout the day without the need for frequent charging.

[0018] Flexible communication and efficient data interaction: It integrates 4G / 5G, WiFi and positioning communication modules, and realizes mobile network access through SIM card slot. The image upload and result return latency is within the second level. It also supports Bluetooth / magnetic connection with the fully automatic storage compartment, realizing multi-angle automatic acquisition of 16 images per batch, which greatly improves the identification efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] Example 1: like Figure 1-4 As shown, this embodiment provides a portable Cordyceps sinensis identification instrument, mainly composed of a housing 1, a touch screen 2, operation buttons 3, an infrared ranging module 4, a high-definition camera 5, a power button 6, and a SIM card slot 7. The device also includes a main control system, a storage system, a communication system, and a power supply system, with each system electrically and data connected via internal circuit boards and signal lines.

[0025] The housing 1 serves as the main support structure for the entire device, preferably made of high-strength engineering plastic or aluminum alloy through integral molding or assembly. The housing 1 has a streamlined design with overall dimensions of 247.2mm × 88mm × 64.1mm. It contains an internal mounting cavity to accommodate the touchscreen 2, internal circuit board, battery pack, and various functional modules. The surface of the housing 1 has mounting openings corresponding to each functional component, all of which are sealed to ensure stable installation and the device's waterproof and dustproof performance. The design of the housing 1 incorporates ergonomic principles, with the center of gravity located slightly below the center of the device, ensuring comfortable grip even during extended use.

[0026] The touchscreen 2 is embedded in the mounting opening on the front of the housing 1 and is precisely assembled with the housing 1 by means of snap-fit ​​or adhesive. The touchscreen 2 is a capacitive touchscreen, preferably 5.5 inches in size, supports multi-touch, and has a touch response time of no more than 100ms. The touchscreen 2 and the housing 1 are sealed with a waterproof sealing ring to prevent moisture and dust from entering the device. As the main human-machine interface, the touchscreen 2 has its display signal input terminal and control output terminal electrically connected to the internal main control system. It is used to display acquired images, identification results, operation menus, and system status information, and to receive user touch operation commands.

[0027] The operation button 3 is located on the side of the housing 1 and is connected to the housing 1 by a snap-fit ​​or screw. The operation button 3 includes, but is not limited to, a camera shortcut key, a mode switch key, and a confirmation key. The signal output of the camera shortcut key is connected to the main control system to trigger the high-definition camera 5 to quickly acquire images; the mode switch key is used to send instructions to the main control system to switch between handheld mode and fully automatic mode; the confirmation key is used to send a confirmation signal to the main control system or enter the next level menu. A silicone sealing ring is provided between the operation button 3 and the housing 1 to ensure the overall protection level of the device.

[0028] The infrared ranging module 4 is installed on the front of the housing 1 near the high-definition camera 5, and is fixed to the housing 1 by screws or clips. The infrared ranging module 4 uses Time-of-Flight (TOF) ranging technology, calculating the target distance by emitting infrared light pulses and receiving reflected light signals. The ranging accuracy is ±2mm, and the ranging range covers 0.1m to 5m. The data output terminal of the infrared ranging module 4 is electrically connected to the data acquisition terminal of the main control system, enabling it to automatically identify the distance between the high-definition camera 5 and the Cordyceps sinensis sample. The main control system then drives the touchscreen 2 to display real-time distance prompts to the user, including three prompt states: "distance too far," "distance appropriate," and "distance too close."

[0029] The high-definition camera 5 is fixed to an internal bracket at the front end of the housing 1, with the optical axis of the lens aligned with the length of the housing 1. The high-definition camera 5 employs a high-pixel image sensor with an effective pixel count of 12 megapixels or higher, supporting high-resolution image and video acquisition. The high-definition camera 5 can automatically adjust exposure parameters under different lighting conditions, and its image data output is connected to the data input of the main control system via an image signal processing link. The high-definition camera 5 works in conjunction with the infrared ranging module 4. When the infrared ranging module 4 detects a suitable distance and sends a signal to the main control system, the main control system automatically triggers the high-definition camera 5 to acquire an image.

[0030] The power button 6 is located on the side of the housing 1 and is connected to the housing 1 via a snap-fit. The output terminal of the power button 6 is electrically connected to the power management unit of the power supply system, and is used to control the power-on and power-off operations of the device. Pressing and holding the power button 6 for more than two seconds will activate the circuit of the power management unit to turn on the device; pressing and holding it again for more than two seconds will turn it off and enter a low-power standby mode. The power button 6 has a built-in LED indicator, the control terminal of which is connected to the power management unit. It indicates the working status of the device through different colors and flashing frequencies: solid green indicates sufficient power, flashing orange indicates charging, and flashing red indicates insufficient power.

[0031] The SIM card slot 7 is located on the side of the housing 1 and is integrally formed with the housing 1 or embedded by a snap-fit ​​mechanism. The SIM card slot 7 is used to install a mobile communication SIM card and supports hot-swapping. The SIM card slot 7 is equipped with an anti-misinsertion mechanism and a spring-loaded mechanism. The communication pins of the SIM card slot 7 are electrically connected to the baseband processor of the internal communication system. Through the inserted SIM card, a data connection is established with the mobile operator's base station, enabling remote data communication between the device and a cloud server.

[0032] The device's internal main control system adopts a dual-core architecture, including a high-performance edge computing module and a microcontroller unit. The edge computing module is responsible for running AI image recognition and identification algorithms, equipped with large-capacity RAM and solid-state storage, providing powerful edge computing capabilities. The microcontroller unit is responsible for real-time task scheduling, sensor data acquisition, peripheral control, and low-power management. The two cores communicate via a high-speed bus to achieve task division and collaborative processing.

[0033] The device's internal communication system integrates a mobile communication module, supporting 4G / 5G full network connectivity, WiFi wireless network, and GPS / BeiDou dual-mode positioning. The communication system's radio frequency terminal connects to the SIM card slot 7 to acquire mobile network communication capabilities, enabling real-time uploading of authentication data and rapid transmission of cloud results.

[0034] The device's internal power supply system uses a rechargeable lithium battery pack, housed in the battery compartment inside the casing 1. The battery pack is charged via a charging port at the bottom of casing 1, supporting fast charging protocols. The power supply system is electrically connected to the main control system, touchscreen 2, high-definition camera 5, and other modules, providing operating voltage for the entire device.

[0035] In use, the user holds the housing 1 and aims the lens of the high-definition camera 5 at the Cordyceps sinensis sample to be identified. The infrared ranging module 4 detects the distance between the camera and the sample in real time and transmits the distance data to the main control system, where the touch screen 2 displays the current distance value and prompts. The user adjusts the holding distance according to the prompts, and when the touch screen 2 displays "Distance is appropriate," the user presses the photo shortcut key on the operation button 3. After receiving the signal, the main control system controls the high-definition camera 5 to automatically acquire the image.

[0036] S1 ranging: The infrared ranging module 4 emits infrared light pulses in real time and receives reflected light signals, calculates and outputs the current shooting distance value to the main control system.

[0037] S2 Distance Judgment: The main control system compares the current distance value with the preset appropriate distance range to determine whether it is "appropriate distance", "too far distance" or "too close distance".

[0038] S3 prompts and controls: Based on the judgment result, unlock / lock the camera signal and output the corresponding prompt ("Can take a picture" or "Please approach / stay away") on the touch screen.

[0039] S4 Image Acquisition: When the camera signal is not locked, the user can trigger the camera to take a picture; when the camera signal is locked, the button is ineffective and the lock remains until the distance is restored.

[0040] S5 Data Upload: After preprocessing, the image is uploaded to the cloud server via 4G / 5G mobile network or WiFi wireless network.

[0041] S6 Result Feedback: The cloud-based AI identification system analyzes and returns identification results and classification information, which are displayed on the touchscreen and support voice broadcast and result export.

[0042] The device supports two working modes: handheld mode and fully automatic mode. In handheld mode, the user manually controls image acquisition, capturing 4 images per batch. In fully automatic mode, the device can connect to the matching fully automatic identification chamber via magnetic contacts or wireless communication, forming a combined usage state. It can automatically acquire 16 images per batch, achieving multi-angle and all-round image acquisition of Cordyceps sinensis.

[0043] After the acquired images are preprocessed by the edge computing module, they are uploaded to the cloud server via a mobile communication network. The cloud-based AI identification system, based on a visual language model and fine-tuning technology, performs multi-dimensional analysis of the images, including appearance, color features, and texture details, and outputs identification results and classification information. The identification results are presented intuitively on the touchscreen 2, and also support voice broadcasting and result export functions.

[0044] Through the above structural design, this portable Cordyceps sinensis identification instrument achieves a high degree of integration and intelligence. The streamlined design and high center of gravity of the shell 1 ensure excellent portability and a comfortable grip; the linkage between the infrared ranging module 4 and the high-definition camera 5 ensures standardized image acquisition quality; the dual-core main control system balances high-performance computing and low-power control; and the support for a large-capacity battery and multiple communication methods enables the device to meet the needs of long-term, high-efficiency identification in complex environments such as production sites and trading sites, effectively solving the problems of strong subjectivity and inconsistent standards in traditional identification methods, as well as the bulkiness and inconvenience of existing equipment.
