Description
Technical Field

[0002] A photosensitive element recording signal acquisition device, with a photosensitive element as its core, can sense information such as light intensity and wavelength, convert the light signal into an electrical signal, process and amplify it through internal circuitry, record and store it, and output digital or analog signals that can be used for analysis. It is widely used in optical detection, environmental monitoring and other fields.
[0003] A search revealed the following publication (announcement) number: CN219626012U, entitled "Signal Acquisition Circuit, Signal Acquisition System, and Photosensitive Detector," which includes: multiple signal acquisition modules for acquiring target signals from different preset locations; and an acquisition channel selection module for adjusting the operating state according to a first or second control command, ensuring that one of the signal acquisition modules is connected to the I2C bus in each I2C communication cycle. This application can reduce the management difficulty of multiple signal acquisition devices.
[0004] The above technical solution has the following shortcomings;

An adjustment mechanism is provided on the side wall of the connecting cover 5 and fixedly connected to the support ring 11. A socket end 13 is fixedly connected to the side wall of the detection and processing component 2. A snap-fit interface 14 is provided on the tube wall of the cylindrical shell 1, and the socket end 13 snaps into the snap-fit interface 14. A dehumidification mechanism is provided in the cavity of the heat dissipation bottom cover 4. The cylindrical shell 1 provides installation space for each component. The segmented snap-fit design facilitates the disassembly and maintenance of the detection and processing component 2 and the power module 3. The heat dissipation bottom cover 4 and the connecting cover 5 are used to provide installation space for each component. The threaded connection facilitates easy opening of the housing for internal maintenance. The conical baffle 6 blocks stray light interference from the sides, improving the accuracy of light signal acquisition. The focusing lens 7 concentrates the light, enhancing the light signal intensity. The protective lens 8 protects the internal optical components. The filter 9 filters out irrelevant wavelengths of light. The first polarizer 10 and the second polarizer 12 work together to adjust the light flux, adapting to different light environments. The adjustment mechanism allows for precise control of the polarizer angle, improving adaptability to different light environments. The connector 13 and card interface 14 facilitate connection to external devices. The dehumidification mechanism keeps the interior dry. This solves the problems of poor adaptability to different light environments and inconvenient maintenance when damage occurs in existing optical sensor signal acquisition devices.
[0032] To precisely adjust the angle of the polarizer and adapt to different lighting environments, such as Figure 1 and 2 As shown, the adjustment mechanism includes an adjustment groove 15, an operating slider 16, and an arc-shaped scale display bar 17. The adjustment groove 15 is provided at one end of the tube wall of the connecting cover 5, and the operating slider 16 is slidably connected thereto. The side wall of the operating slider 16 is fixedly connected to the side wall of the support ring 11.

By moving the sliding operating slider 16 along the adjustment groove 15, the support ring 11 and the second polarizer 12 are rotated. The rotation angle can be precisely controlled by the arc-shaped scale display bar 17, so as to achieve precise adjustment of the light flux and improve the adaptability to different light environments.

The integrated design improves signal processing efficiency, and the support shell 21 protects the internal modules from damage.

The internal and external thread design facilitates connection with the cylindrical shell 1 and the internal thread cover 18. The heat dissipation and dustproof filter 25 ensures heat dissipation while blocking dust, preventing dust accumulation in internal components from affecting performance.
[0036] To enhance heat dissipation and protection performance, such as Figures 1-3 As shown, the side wall of the support shell 21 is provided with multiple heat dissipation holes 26, and the side wall of the cylindrical shell 1 is fixedly connected to an arc-shaped dust filter 27 through the opening. The inner side wall of the arc-shaped dust filter 27 is fixedly connected to a waterproof and breathable membrane 28. The heat dissipation holes 26 are used to accelerate the heat dissipation of the detection and processing component 2. The arc-shaped dust filter 27 and the waterproof and breathable membrane 28 work together to prevent dust and moisture from entering while ventilating and dissipating heat, thus protecting the internal components.
[0037] To reduce light reflection interference and improve the quality of optical signal acquisition, such as Figures 1-3 As shown, the surface of the focusing lens 7 is fixedly connected with an anti-glare matte coating. The anti-glare matte coating reduces the reflection of light on the lens surface, avoids stray light interference, and enables the focusing lens 7 to more efficiently gather effective light, thereby improving the clarity and accuracy of light signal acquisition.
