Description

Technical Field

[0001] This utility model relates to a combined illuminance and ultraviolet light sensor, and more particularly to a digital combined illuminance and ultraviolet light sensor applied in the field of sensors. Background Technology

[0002] Light exposure can cause photochemical reactions in the materials of cultural relics, accelerating their aging or discoloration. This is especially true for organic materials such as textiles, paper, and lacquerware, as well as light-sensitive materials like painted artifacts. Different wavelengths of light cause different degrees of damage to cultural relics. High-energy ultraviolet light and short-wave visible light (λ≤400μm) have a greater impact on the deterioration of cultural relics. Therefore, monitoring the illuminance and ultraviolet radiation in the environment in which cultural relics are preserved is of great significance for their preservation.

[0003] Chinese patent CN221840570U discloses a novel light sensor. This utility model uses a vacuum suction cup structure in conjunction with the main body of the device. Compared with traditional sensors that usually require screws or other fixing devices for installation, this new sensor can be easily adsorbed onto the wall surface using a vacuum suction cup without the need for additional fixing devices. Installation and disassembly are more convenient. Furthermore, due to the characteristics of the vacuum suction cup, this sensor can be easily moved to different positions to adapt to the light measurement needs of different occasions.

[0004] In the process of monitoring the preservation environment of cultural relics, it is necessary to monitor both light and ultraviolet radiation simultaneously, and then calculate the data after monitoring. The detection of relative ultraviolet radiation content requires recording the illuminance of the same measurement point (surface), with the value not exceeding 10 μW / lm. However, the existing light sensors only have the function of monitoring light alone and cannot directly output the relative content of ultraviolet radiation. After detecting light and ultraviolet radiation, manual calculation is still required, which increases the workload of staff and reduces the practicality of the equipment. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that existing light sensors only have a single light monitoring function and cannot directly output the relative content of ultraviolet radiation. After detecting light and ultraviolet radiation, manual calculation is still required, which increases the workload of staff and reduces the practicality of the equipment.

[0006] To address the aforementioned issues, this utility model provides a digital illuminance and ultraviolet (UV) combined sensor, comprising a lower sensor cover. A communication interface and multiple studs are fixedly connected to the upper end of the lower sensor cover. A sensor main board is inserted into the upper end of the studs. A light photodetector and an ultraviolet photodetector are fixedly connected to the upper end of the sensor main board. The light photodetector is located to the left of the ultraviolet photodetector. An illuminance correction filter is fixedly connected to the upper end of the light photodetector, and an ultraviolet filter is fixedly connected to the upper end of the ultraviolet photodetector. A sensor upper cover is fixedly fitted onto the outer surface of the lower sensor cover. An illuminance cosine corrector and an ultraviolet diffuser are fixedly embedded in the upper end of the sensor upper cover. An adjustment assembly is fixedly connected to the rear end of the sensor upper cover. The adjustment assembly includes a fixing rod fixedly connected to the rear end of the sensor upper cover, a screw fixedly connected to the rear end of the fixing rod, a mounting plate on the rear side of the fixing rod, and an adjustment plate fixedly connected to the front end of the mounting plate. An adjustment groove is carved into the surface of the adjustment plate, and the rear end of the screw moves through the adjustment groove.

[0007] The aforementioned digital illuminance and ultraviolet combined sensor can directly detect illuminance and ultraviolet radiation at the same measurement point. Compared with illuminance alone, it better meets the standard requirements. After detecting illuminance and ultraviolet radiation, there is no need for manual calculation by the staff. The illuminance measurement value, ultraviolet measurement value, and relative content of ultraviolet radiation are directly output through calculation, thereby effectively reducing the workload of the staff, improving the practicality of the equipment, and making it more convenient to use.

[0008] As a further improvement of this application, the lower end of the sensor cover is provided with a plurality of screws corresponding to a plurality of studs, the upper end of the screws threadedly through the sensor cover and the studs in sequence, and the lower end of the screws is fixedly connected to a suction cup.

[0009] As a further improvement of this application, the sensor cover includes two circular tubes and a fixed shell fixedly connected between the two circular tubes, with the illumination cosine corrector and the ultraviolet diffuser located at the upper ends of the two circular tubes respectively.

[0010] As a further improvement of this application, the illumination cosine corrector, the illumination correction filter, and the illumination photodetector are coaxial, and the ultraviolet diffuser, the ultraviolet filter, and the ultraviolet photodetector are coaxial.

[0011] As another improvement of this application, both the adjusting plate and the adjusting groove are arc-shaped, and the adjusting plate and the screw are fixedly connected by a nut.

[0012] As another improvement of this application, screw holes are drilled at the four corners of the front end of the mounting plate, and the front end of the mounting plate is provided with multiple bolts that correspond to the multiple screw holes respectively, and the rear thread of the bolts passes through the screw holes.

[0013] In summary, in practical applications, illumination and ultraviolet radiation at the same measurement point can be directly detected. Light passes through an illumination cosine corrector and an illumination correction filter before being incident on the motherboard's photodetector. The photodetector outputs a current signal proportional to the incident light intensity. Simultaneously, light passes through an ultraviolet diffuser and an ultraviolet filter before being incident on the motherboard's ultraviolet photodetector, which also outputs a current signal proportional to the incident light intensity. The microcontroller then calculates the collected illumination and ultraviolet intensity values ​​to determine the relative ultraviolet radiation content. This eliminates the need for manual calculations by operators, directly outputting illumination and ultraviolet measurement values, as well as the relative ultraviolet radiation content. This effectively reduces the workload of operators, improves the practicality of the equipment, and makes it more convenient to use. Attached Figure Description

Detailed Implementation

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figure 1 and Figure 2The following is illustrated: A digital illuminance and ultraviolet (UV) combined sensor includes a sensor lower cover 6. A communication interface 8 and multiple studs 9 are fixedly connected to the upper end of the sensor lower cover 6. A sensor motherboard 5 is commonly inserted into the upper end of the studs 9. The sensor motherboard 5 has an external power supply and a communication interface 8. The motherboard power supply is generated by a high-input voltage LDO, supporting a wide DC voltage supply. The communication interface 8 is a TTL serial port. A light photodetector 4 and an ultraviolet photodetector 10 are fixedly connected to the upper end of the sensor motherboard 5. The light photodetector 4 is located to the left of the ultraviolet photodetector 10. An illuminance correction filter 3 is fixedly connected to the upper end of the light photodetector 4. An ultraviolet filter 11 is fixedly connected to the upper end of the ultraviolet photodetector 10. A sensor upper cover 2 is fixedly fitted onto the outer surface of the sensor lower cover 6. An illuminance cosine corrector 1 and an ultraviolet diffuser 12 are fixedly embedded in the upper end of the sensor upper cover 2. The lower end of the cover 6 is provided with multiple screws 7, each corresponding to multiple studs 9. The upper end of the screws 7 is threaded through the sensor lower cover 6 and the studs 9 in sequence. The screws 7 can fix the sensor lower cover 6 and the studs 9. The lower end of the screws 7 is fixedly connected to a suction cup, which facilitates the support and fixation of the sensor lower cover 6. The sensor upper cover 2 includes two round tubes and a fixed shell fixedly connected between the two round tubes. The illumination cosine corrector 1 and the ultraviolet diffuser 12 are located at the upper ends of the two round tubes respectively. The illumination cosine corrector 1, the illumination correction filter 3 and the illumination photodetector 4 are coaxial. The ultraviolet diffuser 12, the ultraviolet filter 11 and the ultraviolet photodetector 10 are coaxial, which facilitates the light to pass through the illumination cosine corrector 1 and the illumination correction filter 3 and be incident on the illumination photodetector 4 on the motherboard.

[0025] Figure 3 The diagram shows that light passes through an illumination cosine corrector 1 and an illumination correction filter 3, and is incident on an illumination photodetector 4 on the motherboard. The illumination photodetector 4 outputs a current signal proportional to the incident light intensity. This current signal is converted into a voltage signal by an I / V converter. The microcontroller reads the voltage signal value collected by the ADC through the I2C interface and further converts it into an illumination intensity value E in lux (lx), which is then output through a serial port. Similarly, light passes through an ultraviolet diffuser 12 and an ultraviolet filter 11, and is incident on an ultraviolet photodetector 10 on the motherboard. The illumination photodetector 4 outputs a current signal proportional to the incident light intensity. This current signal is converted into a voltage signal by an I / V converter. The microcontroller reads the voltage signal value collected by the ADC through the I2C interface and further converts it into an ultraviolet intensity value I in μW / cm², which is then output through a serial port. Using the collected illumination intensity value E and ultraviolet intensity value I, the microcontroller calculates the relative ultraviolet radiation content R = I × 10⁴ / E in μW / lm, which is then output through a serial port.

[0026] In use, it can directly detect illumination and ultraviolet radiation at the same measurement point. When light passes through the illumination cosine corrector 1 and the illumination correction filter 3, it is incident on the illumination photodetector 4 on the main board. The illumination photodetector 4 outputs a current signal proportional to the incident light intensity. At the same time, when light passes through the ultraviolet diffuser 12 and the ultraviolet filter 11, it is incident on the ultraviolet photodetector 10 on the main board. The illumination photodetector 4 outputs a current signal proportional to the incident light intensity. The microcontroller then calculates the collected illumination intensity value and ultraviolet intensity value to obtain the relative content of ultraviolet radiation. There is no need for manual calculation by the staff. It directly outputs the illumination measurement value, ultraviolet measurement value, and relative content of ultraviolet radiation, thereby effectively reducing the workload of the staff, improving the practicality of the equipment, and making it more convenient to use.

[0027] Second implementation method:

[0028] This embodiment adds an adjustment component to the first embodiment, while the rest remains the same as the first embodiment.

[0029] Figure 4 , Figure 5 and Figure 6 As shown: An adjustment assembly is fixedly connected to the rear end of the sensor cover 2. The adjustment assembly includes a fixing rod 13 fixedly connected to the rear end of the sensor cover 2. A screw 14 is fixedly connected to the rear end of the fixing rod 13. A mounting plate 15 is provided on the rear side of the fixing rod 13. An adjustment plate 16 is fixedly connected to the front end of the mounting plate 15. An adjustment groove 17 is chiseled on the surface of the adjustment plate 16. The rear end of the screw 14 moves through the adjustment groove 17. Both the adjustment plate 16 and the adjustment groove 17 are arc-shaped. The adjustment plate 16 and the screw 14 are fixedly connected by a nut. Screw holes are chiseled at the four corners of the front end of the mounting plate 15. The front end of the mounting plate 15 is provided with multiple bolts 18, each corresponding to a multiple screw hole. The rear thread of the bolt 18 passes through the screw hole.

[0030] In use, the screw 14 can be inserted into the adjustment groove 17, and the screw 14 can be fixed to the adjustment plate 16 by the nut. Then, the mounting plate 15 can be fixed to the wall by the bolts 18. When it is necessary to adjust the angle of the sensor, the nut can be loosened to allow the sensor to slide inside the adjustment groove 17, thereby adjusting the angle of the sensor around the central axis of the adjustment plate 16. The nut can then be tightened to fix the fixing rod 13, which facilitates the adjustment of the sensor angle and effectively improves the practicality of the sensor.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
