Description

Technical Field

[0001] This utility model belongs to the field of spectral detection, specifically relating to a portable visual spectral detection device. Background Technology

[0002] The principle of spectroscopic detection is based on the interaction between light and matter. Light is an electromagnetic wave with different wavelengths and frequencies. When light strikes a substance, phenomena such as reflection and absorption occur, causing changes in the wavelength and intensity of the light, forming different spectra. Each substance has its unique spectral characteristics, much like a fingerprint, which can be used to analyze the composition and structure of the substance. Spectroscopic detection is widely used in many industries and fields, including pharmaceuticals, food, biology, ceramics, petroleum, glass, metals, inks, paper, ores, coatings, and soil.

[0003] In existing technologies, the main body and probe of a spectral detection device are usually integrated on the same carrier platform. When adjusting the detection area during use, the entire device needs to be operated, which is very inconvenient.

[0004] In view of this, there is an urgent need for a portable visual spectral detection device. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] refer to Figure 1-3 The portable visualization spectral detection device shown includes a spectral detection system body, which includes a housing 1 and an optical fiber spectrometer disposed inside the housing 1. A strap structure is provided on the housing 1.

[0030] The probe body includes a handheld housing 2 and a probe assembly. The probe assembly is located at one end of the handheld housing 2 and includes a fiber optic probe 3 and an RGB color camera 4. The front end of the fiber optic probe 3 has an imaging lens used to position the light-receiving angle field of view of the fiber optic cable (the fiber optic cable is a single-core circular shape, and its field of view is determined by its own field of view angle; similarly, a small point as the source point will form a large circle of different areas at different distances (in reality, the field of view size is different at different distances), and the field of view angle of this fiber optic cable is fixed; the only variable in the shooting field of view is the distance; while the RGB color camera 4...). The field of view of the GB camera is very large, much larger than that of the fiber optic cable; that is to say, the field of view of the RGB color camera 4 can always cover the field of view observed by the fiber optic probe 3; by using lasers and other methods to measure the size of the light spot at different distances and then marking its position in the RGB field of view, the RGB color camera 4 can observe and capture the target area in real time, and mark it with specific markers, determine the acquisition area each time and save the corresponding image information, providing support for subsequent data processing and analysis, and simultaneously recording the regional spectrum and corresponding image information, expanding the visualization capabilities of traditional single-point acquisition spectrum;

[0031] Optical fiber is used to connect the probe body and the spectral detection system body.

[0032] Based on the above structure, by setting a shoulder strap structure on the housing 1, the main body of the spectral detection system is made into a portable backpack shape, which is convenient to carry and operate. Most of the components of the spectral detection device are installed in the housing 1, and most of the weight of the spectral detection device is carried on the user's back. The probe assembly is supported by the handheld housing 2. When in use, the user holds the handheld housing 2 to control the probe assembly for detection, which reduces the burden of operating the probe assembly and better reflects the humanized design.

[0033] like Figure 2 As shown, the main body of the spectral detection system also includes a control motherboard 11, a wireless receiver 12, an integrated circuit board 13, a buzzer 14, and several interfaces 15 on one side of the housing 1. The interfaces 15 mainly include an external signal transmission interface (network cable), a charging interface, a power indicator light, and an optical fiber inlet.

[0034] Furthermore, this application also includes a display, which serves as a visual operating interface and avoids the drawbacks of being a non-imaging system. It can provide real-time feedback on the observation area of ​​the auxiliary camera (RGB color camera) and the fiber optic field-of-view positioning area.

[0035] The probe body also includes a cosine correction module 5 located at the end of the handheld housing 2 furthest from the probe assembly. The optical fiber is a Y-type fiber, with one end connected to both the cosine correction module 5 and the probe assembly, and the other end connected to the fiber optic spectrometer. A single-sided homogenizing glass is installed at the light inlet of the cosine correction module 5. The cosine correction module 5 is used to collect real-time light intensity signals. It has an internal shutter structure, which can be automatically controlled to close / close via a serial port protocol. When the probe assembly is collecting signals, the shutter is in an open-loop state. The single-sided frosted glass at its upper end can effectively scatter light from different angles, making the light entering the fiber relatively uniform, thus homogenizing the light and preventing oversaturation, providing a reference for data calibration. The Y-type fiber design allows for the simultaneous acquisition and transmission of ground target signals (from the probe assembly) and signals for sky-corrected light intensity (from the cosine correction module 5). The cosine correction module 5 ensures that each acquired data can form a reference analogy with its corresponding light intensity (light source) signal, aiding in quantitative data analysis and calibration.

[0036] Further optimizations include, for example Figure 4 As shown, the probe body also includes an extension rod (a telescopic rod can be used). The handheld housing 2 is provided with a mounting port 21 that is adapted to the extension rod. The probe body can be operated by attaching the extension rod to the mounting port 21, which is convenient for collecting data of distant targets; or it can be operated by directly holding the handheld housing 2 to collect data of close targets.

[0037] A further optimization is that a GPS positioning module is installed inside the handheld housing 2 to achieve accurate positioning.

[0038] like Figure 1 As shown, the carrying strap structure includes several hanging loops 16 on the case 1 and a carrying strap threaded through the several hanging loops 16. The case 1 is carried on the back by the carrying strap, freeing the user's hands and reducing the user's operating difficulty and burden.

[0039] In summary, by incorporating a shoulder strap structure on the housing 1, the main body of the spectral detection system adopts a portable backpack-like form, making it convenient to carry and operate. Most of the components of the spectral detection device are installed inside the housing 1, allowing the user to carry most of the weight of the spectral detection device on their back. The probe assembly is supported by the handheld housing 2. When in use, the user holds the handheld housing 2 to control the probe assembly for detection, reducing the burden of operating the probe assembly, better reflecting a user-friendly design, and improving ease of use.

[0040] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
