Description

Technical Field

[0001] The invention belongs to the field of monitoring camera components, and in particular relates to a double-sided anti-reflection coating electrochromic film for a monitoring camera, and a control system and a control method thereof. Background Art

[0002] At present, surveillance cameras are widely used, and a large number of surveillance cameras need to be installed in outdoor environments for use. For example, vehicle autonomous driving technology is rapidly becoming popular, and the performance of surveillance cameras used in vehicles is crucial for safe driving. Since vehicles must meet the requirements of all-weather driving, the intensity of sunlight outside the vehicle varies significantly with day and night and seasons. Surveillance cameras are prone to overexposure when the light is strong at noon, and are prone to blurred images and dark areas when the light is low at night, which seriously affects the normal camera function and may bring safety hazards to autonomous vehicles. Although surveillance cameras can adjust the captured images through the lens aperture and image sensor sensitivity, due to cost considerations, surveillance cameras are usually not equipped with high-performance apertures and photosensitive elements, and the adjustment ability is limited. Therefore, it is necessary to design other methods to eliminate the above-mentioned camera "bright effect shadow" phenomenon so that the camera can record clear images under different lighting conditions.

[0003] Electrochromic (EC) refers to the phenomenon that the optical properties of a material (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible changes under the action of an external electric field. Electrochromic glass is currently widely used in architectural glass curtain walls, car window glass, car anti-glare rearview mirrors and other fields. However, it is not currently used in products such as cameras and surveillance camera lenses. If the existing electrochromic film is to be installed in front of the camera lens, there are the following problems: 1. Currently, the application areas of electrochromic films usually only require switching between light-transmitting and light-opaque to meet application requirements. However, if used as a dimming film in front of a camera lens, it is necessary to accurately control the transmittance change of the electrochromic film to achieve precise control of the light intensity received by the camera.

[0004] 2. When the camera is shooting in low light conditions, the maximum transmittance of the lens is very high, and the existing electrochromic film cannot meet the requirement.

[0005] 3. Existing electrochromic lenses usually coat the conductive layer directly on the lens. Since the conductive layer material has poor adhesion to the glass with the anti-reflective coating, the two are easy to loosen and fall off or are not tightly attached to form a cavity. When air penetrates into the cavity, bubbles are formed in the lens, affecting the light transmittance of the lens. If the conductive layer is processed on the substrate glass first and then the anti-reflective coating, although the adhesion between the coatings can be improved, the anti-reflective coating with poor conductivity is added between the electrochromic layer and the conductive layer, which increases the resistance and causes the electrochromic layer to change color slowly.

[0006] 4. When the existing electrochromic film returns to a transparent state from a colored state, the external electric field is usually removed, and the electrochromic film discharges naturally until it returns to transparency. The discharge process usually takes several seconds or even tens of seconds, which cannot meet the functional requirements of rapid camera control. Summary of the invention

DETAILED DESCRIPTION Embodiment 1

[0020] Embodiment 1 of the present invention provides a double-sided anti-reflection coating electrochromic film, such as Figure 1 , 2As shown in , 3, it comprises a first lens and a second lens, and a first protruding seat is processed on both sides of the upper edge of the first lens. The first lens comprises a first substrate 1, and the first substrate 1 is plated with a first outer anti-reflection coating 3 and a first inner anti-reflection coating 4 on both sides, and a first intermediate coating 5 is plated on the first inner anti-reflection coating 4, and a first conductive layer 6 is plated on the first intermediate coating 5; a second protruding seat is processed on both sides of the lower edge of the second lens; the second lens comprises a second substrate 2, and the second substrate 2 is plated with a second outer anti-reflection coating 11 and a second inner anti-reflection coating 10 on both sides, and a second intermediate coating 9 is plated on the second inner anti-reflection coating 10, and a second conductive layer 8 is plated on the second intermediate coating 9. The first conductive layer 6 and the second conductive layer 8 are placed adjacently and parallel to each other, and a slit is left between the first conductive layer 6 and the second conductive layer 8, and a sealing rubber frame 12 is provided around the slit, and the sealing rubber frame 12 is fixedly connected to the edges of the first conductive layer 6 and the second conductive layer 8; the slit is filled with a fluid electrochromic material to form an electrochromic layer 7. A first electrode 13 is fixedly installed on each side of the first conductive layer 6 of the two first protruding seats of the first lens, and the bottom end of the first electrode 13 is adjacent to the top end of the packaging rubber frame 12; a second electrode 14 is fixedly installed on each side of the second conductive layer 8 of the two second protruding seats of the second lens, and the top end of the second electrode 14 is adjacent to the bottom end of the packaging rubber frame 12.

[0021] The first protrusion seat of the first lens is set on the upper edge, and the second protrusion seat of the second lens is set on the lower edge, so that the installation positions of the electrodes will not interfere with each other, the electrode space arrangement is more reasonable, and the electrode installation is more convenient; the first protrusion seat and the second protrusion seat are processed on both sides of the edge of each lens respectively, and an electrode is installed on each protrusion seat, which can make the electric field distribution on the conductive layer more uniform.

[0022] The double-sided anti-reflection coating electrochromic film is installed in front of the camera lens. The electrochromic film is electrically connected to the control system and is driven and controlled by the control system. When the external light intensity exceeds the light intensity preset by the main control module, the control system applies a positive voltage to the first conductive layer 6 and the second conductive layer 8 through the first electrode 13 and the second electrode 14, and a positive electric field is formed between the two conductive layers. The electrochromic layer 7 changes color under the action of the positive electric field. In this state, the electrochromic film changes from high transmittance to low transmittance, and the light intensity received by the camera is reduced. When the external light intensity is lower than the preset light intensity, the control system applies a negative voltage to the double-sided anti-reflection coating electrochromic film, and a reverse electric field is formed between the two conductive layers. The electrochromic layer 7 quickly returns to colorless transparency under the action of the reverse electric field. In this state, the electrochromic film changes from low transmittance to high transmittance, and the light intensity received by the camera lens is increased. When the control system does not apply a driving voltage to the double-sided anti-reflection coating electrochromic sheet, there is no external electric field in the electrochromic layer 7, and it discharges naturally, slowly recovering to a colorless and transparent state or maintaining a colorless and transparent state.

[0023] The first substrate 1 and the second substrate 2 adopt AR (Anti-Reflection) double-sided anti-reflection coating technology. After adding anti-reflection coatings on both sides, the transmittance in the wavelength range of 400nm-1100nm is greatly improved, and the maximum light transmittance of a single substrate reaches 99%. The average reflectivity is less than 4%, and the minimum reflectivity value is less than 0.5%. The overall transmittance of the electrochromic film is greater than 85% in a completely transparent state. The overall visual color difference of the electrochromic film is small, the thickness is small, and the structure is thin and light. In the working state, the transmittance changes with the change of light and the chromaticity. The transmittance in a strong light environment can be reduced to 16% at the lowest, which effectively reduces the whitening of the picture due to strong light, making the image clearer and the layers more distinct.

[0024] The first outer anti-reflective coating 3, the first inner anti-reflective coating 4, the second outer anti-reflective coating 11 and the second inner anti-reflective coating 10 are all silicon nitride coatings. The processing technology of the anti-reflective coating is as follows: a silicon nitride coating is formed on the glass surface by vacuum magnetron sputtering coating using a silicon target and nitrogen, and the reaction chemical formula is: 3 Si(s) + 2 N2(g) → Si3N4(s). The advantages of using silicon nitride for the coating are: the silicon nitride coating has high adhesion to the glass, high surface strength after coating, and good anti-reflective effect. The above anti-reflective coating can also be processed with silicon dioxide material or other oxide materials with anti-reflective effect.

[0025] The process implementation method of the silicon nitride layer is to apply 3KW of electrical energy to the silicon target and start nitrogen emission with a flow rate of 280±10sccm. When the silicon target is energized, it will produce high temperature and bombard atoms through a physical process, that is, the silicon target sublimates into silicon molecules. Through the magnetron directional acceleration method, the silicon molecules are accelerated into high-energy particles. The silicon molecules pass through the nitrogen layer, and the nitrogen is also heated up. The silicon molecules and nitrogen molecules react chemically at high temperatures to form silicon nitride. The silicon nitride after the reaction is a particle with extremely high speed. Through physical bombardment, the atoms pass through the vacuum and finally deposit on the surface of the glass silicon oxide layer to form a silicon nitride layer.

[0026] The first conductive layer 6 and the second conductive layer 8 are made of indium tin oxide. The indium tin oxide coating has good light transmittance and conductivity. The conductive layer can also be processed with other transparent conductive materials in a film state.

[0027] The first intermediate coating 5 and the second intermediate coating 9 are made of tin oxide material. Adding an intermediate coating has the following advantages: the prior art usually directly coats a thin film conductive layer outside the anti-reflective coating. Due to the poor physical adhesion between the conductive layer material and the anti-reflective coating material, the two are easy to loosen and fall off or are not tightly attached to form a cavity. When air penetrates into the cavity, bubbles will form in the lens, affecting the light transmittance of the lens. Therefore, an intermediate coating of tin oxide material is added between the conductive layer and the anti-reflective coating. Through a large number of material tests, it is found that the tin oxide film not only has good light transmittance, but also has strong adhesion to the silicon nitride anti-reflective coating and the indium tin oxide conductive layer. Therefore, the use of tin oxide material to process the intermediate coating can effectively solve the problem of adhesion.

[0028] The processing technology of each of the above-mentioned intermediate coating layers and conductive layers can adopt the magnetic sputtering method.

[0029] The first electrode 13 is bonded to the first lens through conductive gel, and the lower edge of the first electrode 13 is also bonded to the upper side of the packaging frame 12 through conductive gel; the second electrode 14 is bonded to the second lens through conductive gel; the upper edge of the second electrode 14 is also bonded to the lower side of the packaging frame 12 through conductive gel. The conductive gel can make the electrode more firmly bonded to the conductive layer, and can make the electrode adhere more evenly and have better conductivity; the first electrode 13, the second electrode 14 and the packaging frame 12 are bonded, which further strengthens the installation of the electrodes.

[0030] The electrochromic material in the electrochromic layer 7 is selected from violet, and other liquid or gel electrochromic materials may also be selected. When processing the electrochromic layer 7, firstly, the first lens and the second lens are placed opposite to each other, with the side with the conductive layer facing inward, a slit is formed between the two lenses, the slit is filled with fluid electrochromic material and all air is ensured to be exhausted, and finally the sealing rubber frame 12 is used to seal the periphery of the slit. Embodiment 2

[0031] The second embodiment of the present invention provides a double-sided anti-reflection coating electrochromic film control system, which is used to control the double-sided anti-reflection coating electrochromic film described in the first embodiment, such as Figure 4 As shown, the control system of the double-sided anti-reflection coated electrochromic film includes a power supply voltage regulating module, which is electrically connected to the standard power supply; a voltage regulator is provided in the power supply voltage regulating module for reducing the supply voltage of the standard power supply to 5V for output; the power supply voltage regulating module supplies power to the main control module, the photosensor module and the electrochromic drive module through electrical connection; the main control module is electrically connected to the photosensor module and the electrochromic drive module respectively; the electrochromic drive module is electrically connected to the double-sided anti-reflection coated electrochromic film.

[0034] Through the button switch module, the staff can manually turn off the main control module when automatic control is not needed, such as at night. At this time, the electrochromic film does not change color and always maintains the maximum transmittance; the over-temperature protection module is used to detect the internal temperature of the camera. When the temperature is higher than the set upper limit of the operating temperature, the control system stops running to reduce operating heat.

At the same time, the electrochromic drive module leads to a control feedback voltage and sends it to the main control module to control the transmittance of the electrochromic film.

10. The control method of the double-sided anti-reflection coating electrochromic film control system according to claim 9, characterized in that: When the photosensitive module detects that the light intensity is too high, the main control module sends a positive voltage drive signal, and the electrochromic drive module passes a positive voltage through the first conductive layer (6), generating a positive electric field between the two conductive layers, causing the electrochromic layer (7) to change color, and the light transmittance to decrease, thereby reducing the light intensity behind the electrochromic film until the light intensity drops back to a preset standard value range; When the photosensitive module detects that the light intensity is too low, the main control module sends a negative voltage drive signal, and the electrochromic drive module passes a negative voltage through the second conductive layer (8), generating a reverse electric field between the two conductive layers, causing the electrochromic layer (7) to recover its transparency and increase its transmittance, thereby increasing the light intensity behind the electrochromic film until the light intensity returns to a preset standard value range; When the automatic control is turned off, the key switch module sends a signal to the main control module, and the main control module sends a positive pressure shutdown signal and a negative pressure shutdown signal at the same time, and the electrochromic drive module stops energizing the electrochromic sheet; When the over-temperature protection module detects that the actual temperature is too high, or when the power supply voltage regulation module detects that the input power is abnormal, the main control module stops running.
