[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0048] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0049] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details to obscure the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0050] The existing light source generating devices are not convenient for adjusting the light flux, difficult to calibrate, and complex to install. The present invention adopts a simple structural design, is easy to process, has a large internal space, is light overall, and has a more effective heat dissipation function. The device can support different types of light sources including large spot and small spot light sources, and has high scalability, and adapters can be customized according to the requirements of different detection windows. In addition, the present invention also realizes the automatic calibration function of the light source, which improves the accuracy and stability of the light source.

[0051] In a specific embodiment, Figure 1-18 As shown, the light source device provided by the present invention includes a storage cabin, a light source, a calibration mechanism and a controller; wherein the storage cabin is installed on the tank body flange sight glass of the storage tank, and the storage tank can be used in various scenarios where the tank body is used, such as fermentation and chemical synthesis; the storage cabin can be a cabin structure of various forms, and the storage cabin is installed on the tank body flange sight glass through a connector or through its own structure. For example, the storage cabin can include a bottom plate and a top cover, and the top cover can be set into an arc structure, and the bottom of the top cover is fixedly connected to the bottom plate. In order to ensure ventilation, multiple ventilation channels can also be opened on the top cover.

[0052] The light source is installed in the accommodating chamber, and the light source is specifically at least one halogen bulb to provide the light source required for calibration. The calibration mechanism is installed in the accommodating chamber, and the calibration mechanism includes an optical fiber, a collimating mirror, and an electromagnetic valve. The tank flange sight glass, the optical fiber, and the collimating mirror constitute an optical path, and the electromagnetic valve controls the conduction and cutoff of the optical path by opening and closing; the controller is used to obtain a trigger instruction and a current ambient temperature, and generate an action instruction according to the trigger instruction and the current ambient temperature, and the action instruction is used to control the rotation of the electromagnetic valve of the electromagnetic element to open or close the optical path.

[0053] That is to say, when the controller receives a trigger instruction and the current ambient temperature meets the requirements, an action instruction is generated. For example, the controller presets a normal operating temperature range (for example, 18-25°C), and the trigger instruction is to start calibration. After the comparison finds that the current temperature value is within the preset temperature threshold range, a calibration instruction is generated. The solenoid valve acts after receiving the calibration instruction and opens the light path. For another example, if the trigger instruction is to start calibration, but the current ambient temperature exceeds the preset temperature threshold range, no calibration instruction will be generated. When the trigger instruction is to stop calibration, the temperature value still needs to be within the specified range, and the solenoid valve is controlled to act in the opposite direction to close the light path. In this way, the current ambient temperature is integrated into the control algorithm, and calibration is performed only when the environment meets the calibration conditions, avoiding the influence of environmental factors on the calibration results and improving the accuracy of calibration. At the same time, the automatic control method is used to open and close the light path, which improves the automation performance.

[0054] Furthermore, in order to improve the compactness of the structure and ensure the straight transmission of the optical path, the measuring end of the accommodating cabin has an opening, and the light source device also includes a front cover, which is installed at the measuring end of the accommodating cabin and blocks the opening. The front cover is provided with a center hole, and the central axis of the optical fiber, the collimating mirror and the center hole coincides. In order to facilitate installation with the view mirror, an adapter plate is detachably installed on the front cover, and a through hole is provided on the adapter plate. The through hole is coaxially arranged with the center hole, and is installed on the view mirror using the adapter plate. Specifically, the adapter plate is fitted with the protruding part of the front cover, and is fixed to the three holes around the front cover by bolts.

[0055] In some embodiments, the light source device further comprises a support plate, the support plate is arranged in the accommodating cabin, the support plate is mounted on the bottom plate, a fiber mounting hole and a light source mounting hole are provided on the support plate, the collimator is installed in the fiber mounting hole, one end of the fiber is installed in the fiber mounting hole and is coaxially arranged with the collimator, and the light source is installed in the light source mounting hole. The optical fiber is installed on the support plate, half of the fiber mounting hole provided in the center of the support plate is installed with the collimator, and the other half is installed with the optical fiber, the optical fiber is located behind the collimator, and the optical fiber and the collimator are installed in a straight line to ensure coaxiality.

[0056] In this way, the light source and the optical fiber are installed in the accommodating cabin through the support plate, which improves the installation effect and the compactness of the structure. The support plate is also equipped with a mounting frame, through which necessary electrical components such as circuit boards are installed.

[0057] In order to ensure the intensity of the light source, there are multiple halogen bulbs, and each of the halogen bulbs is arranged around the collimator. In this embodiment, there are four halogen bulbs, which are evenly distributed around the collimator. In principle, halogen bulbs are used because the light wavelength range they provide is relatively large. The near-infrared spectrum acquisition system served by this light source device needs to be in the near-infrared band (this product specifically refers to 900-1700nm wavelength). Not all bulbs and light emitters can provide this light. Considering factors such as performance, cost, and attenuation, halogen bulbs are preferred. Structurally, all light sources appearing in this device are bulbs, and all bulbs are halogen bulbs.

[0058] In some embodiments, the electromagnetic element includes a solenoid valve, a reference plate and an electromagnet; wherein the reference plate is connected to the swinging part of the solenoid valve and rotates with the swinging part to block or avoid the center hole of the front cover; the electromagnet is arranged on both sides of the swinging part and drives the swinging part to rotate when power is turned on. The reference plate is cut into a circle and pasted on the swinging part of the solenoid valve. When power is turned on, the solenoid valve rotates the swinging part to the center hole position of the front cover. There are magnets on both sides of the swinging part. When power is turned on, magnetic attraction is generated to cause the swinging part of the solenoid valve to swing up and down. Fig.14 The circular part on the left side of the solenoid valve shown in FIG. 1 is the swing part.

[0059] In addition to the above light source device, the present invention also provides a calibration control method based on the above light source device, the method comprising:

[0060] Get the trigger command and current ambient temperature;

[0061] An action instruction is generated according to the trigger instruction and the current ambient temperature, and the action instruction is used to control the rotation of the electromagnetic valve of the electromagnetic element to open or close the light path.

[0062] The current ambient temperature is acquired by other instruments (built-in sensors of the spectrometer) and then transmitted to the controller, usually as temperature information. The current ambient temperature will be preset with a valid range, and instructions will only be allowed to be sent when the current ambient temperature is within the valid range. The opening and closing strategies are related to the actual engineering requirements. In most scenarios, the strategy is: when the temperature change exceeds a certain threshold, the host computer considers that a combined action needs to be performed: calibration, then the solenoid valve closes the light path for a specified period of time, and then the solenoid valve opens to resume operation.

[0063] The present invention also provides a calibration control device based on the light source device as described above, the device comprising:

[0064] A data acquisition unit, used to obtain trigger instructions and current ambient temperature;

[0065] The instruction generating unit is used to generate an action instruction according to the trigger instruction and the current ambient temperature, wherein the action instruction is used to control the rotation of the electromagnetic valve of the electromagnetic element to open or close the light path.

[0066] In one or several of the above-mentioned specific embodiments, the light source device provided by the present invention integrates both the light source and the calibration mechanism in the accommodation cabin, and installs the accommodation cabin on the tank flange sight glass, which has a good integration effect, a simple and compact structure, and avoids the problem of cumbersome installation and correction caused by the split structure; at the same time, the device can support different types of light sources including large spot and small spot light sources, and has high scalability, and adapters can be customized according to the needs of different detection windows. Specifically, scalability refers to the aforementioned structures such as the adapter plate and the support port. This part of the structure can be modified according to the structure and environmental requirements of the target tank to be installed, and even further new structures can be added to serve the installation difficulty or additional requirements. This modification will not change the function and structure of the parts in the accommodation cabin such as the light source and the calibration mechanism, and is an extensibility preparation that serves modular design. In addition, the present invention realizes automatic calibration of the light source through data acquisition and algorithms.

[0067] For ease of understanding, the structural composition and working process of the light source device provided by the present invention are briefly described below by taking a specific usage scenario as an example.

[0068] like Figure 1-18 As shown, the light source device provided by the present invention includes a top cover 1 (such as Figure 8 As shown), front cover 2 (as Fig. 9 As shown), bottom plate 3 (as Fig.10 As shown), the top cover 1, the front cover 2 and the bottom plate 3 form a storage compartment; the light source device also includes a support plate 4 (as shown) arranged inside the storage compartment Fig.11 As shown), halogen bulb 5 (as Fig.12 As shown), collimator 6 (as Fig.13 As shown), electromagnetic element 7 (as Fig.14 As shown), adapter plate 8 (as Fig.15 As shown), optical fiber 9 (as Fig.16 As shown), mounting frame 10 (as Fig.17 When installing, first install the electromagnetic component 7 on the front cover 2, install four halogen bulbs 5 and collimator 6 on the support plate 4, install the required circuit board and other electrical components on the mounting frame 10, install the above-mentioned installed components on the bottom plate 3, match the optical fiber 9 with the collimator through the hole in the middle of the support plate 4, and pass the other end of the optical fiber through the hole reserved at the rear of the top cover 1. The holes reserved at the rear of the top cover 1 are respectively used to install components such as fans and switches. Finally, the top cover 1 is fixed to the bottom plate 3. The adapter plate 8 is mainly used to connect the device to the tank flange sight glass. The adapter plate 8 is first fixed to the flange sight glass, and then the device is fixed to the adapter plate 8. Finally, the entire light source device can be fixed on the tank flange sight glass to provide light source for the spectrometer during the spectrometer detection process.

[0069] During the test, the light source device with automatic calibration is first installed on the tank window, the power is turned on, the fan starts to work, the light source is controlled by the computer to emit light, the halogen lamp 5 is turned on, the light source irradiates the medium in the tank through the window, and then reflects the light through the window to the inside of the light source (the inside of the light source refers to the inside of this device, the front cover ( Fig. 9) The rear end part can be called the interior), enters the optical fiber 9 through the collimator 6, and a convex mirror is embedded inside the collimator. The convex mirror can gather the light reflected back to the inside of the light source into a point. Since the collimator and the optical fiber are in a straight line, the converged light point can be directly focused on the front end of the optical fiber and enter the optical fiber. The collimator 6 allows enough light to enter the optical fiber 9. The light enters the optical fiber 9 through the collimator 6 and then enters the spectrometer (the spectrometer is placed at the other end of the optical fiber) through the optical fiber 9 for spectral analysis. When the light source calibration is required, the controller receives the instruction to control the electromagnetic element 7 to work. The swing part of the electromagnetic element 7 moves upward, and the end point of the movement just blocks the center hole of the front cover. At this time, the light source is turned on, and the light shines on the reference plate on the electromagnetic element. The light returns to the collimator and the optical fiber to enter the spectrometer for light source calibration. After the calibration is completed, the electromagnetic element actuator is controlled by the computer to rotate downward. At this time, the center hole of the front cover is not blocked and can be collected normally.
