Diamond has a wide light transmission bandwidth and low light absorption rate, that is, the transmittance is very high. Diamond has good light transmittance in the infrared light band, and its transmittance is as high as 90%.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, the present invention provides an optical module intelligent light window system, comprising:

[0041] A power module 7 and a determination module 8, a control module 9, a selection module 10 and a switching module 11, all of which are connected to the power module 7;

[0042] The power supply module 7 is used to supply power to the determination module 8, the control module 9 and the selection module 10. The determination module 8 is used to perform a band analysis on the input light using a spectral analysis technique to obtain a light beam band information set and determine the input light type corresponding to the input light according to the light beam band information set. The control module 9 is used to obtain the changing voltage data according to the light beam band information set and determine the corresponding conversion instruction according to the changing voltage data. The selection module 10 is used to select the corresponding light window according to the input light type. The switching module 11 is used to switch the current light window according to the corresponding conversion instruction.

[0043] Specifically, Figure 2 As shown, the light beam enters the intelligent light window system, which includes a determination module 8, a control module 9, a selection module 10 and a power module 7. First, the light beam enters the determination module 8, and the visible spectrometer, the near-infrared spectrometer and the infrared spectrometer analyze the wavelength band of the light beam, determine the type of the light beam, and pass the spectral data obtained by the determination module 8 to the control module 9. The control module 9 is used to control the entire system, and is composed of a Stm32 chip, a sensor and an A / D sensor. The control module 9 obtains a digital image signal and passes the obtained signal to the selection module 10, wherein the selection module 10 is divided into an infrared photon module and a visible photon module. If the light beam obtained by the analysis is The infrared light enters the infrared photon module. If the light beam obtained by analysis is visible light, it enters the visible photon module, wherein the light window used for the infrared light is a diamond light window 5. Since diamond has good light transmittance in the infrared light band, its transmittance is as high as over 90%. By utilizing the high thermal conductivity, high composition uniformity and stability of diamond for high-power laser output, a more powerful and stable high-efficiency light source can be prepared. If the light beam obtained by analysis is visible light, a sapphire light window 6 is used. Since sapphire has strong light transmittance in the visible light band, with a light transmittance of 80%, the diamond light window 5 and the sapphire light window 6 are combined to produce an intelligent light window system.

[0044] Furthermore, the determination module 8 includes:

[0045] Spectral line generation submodule, first waveband measurement submodule, second waveband measurement submodule, third waveband measurement submodule;

[0046] The spectral line generation sub-module is used to generate characteristic spectral lines of different wavelengths based on the input light. The first band determination sub-module measures the 380 - 760 nm band of the characteristic spectral lines using a visible light spectrometer to obtain a first subset of beam band information. The second band determination sub-module measures the 760 nm - 2.5 m band of the characteristic spectral lines using a near-infrared spectrometer to obtain a second subset of beam band information. The third band determination sub-module measures the 2.5 - 3 m band of the characteristic spectral lines using an infrared spectrometer to obtain a third subset of beam band information.

[0047] Specifically, the device used by the determination module 8 is a spectral analyzer. When an atom transitions from a higher energy level to the ground state or other lower energy levels, it will release excess energy, which is radiated in the form of electromagnetic waves of a certain wavelength. The wavelength of each emitted spectral line depends on the energy difference between the two energy levels before and after the transition. Since there are many energy levels in an atom, after the atom is excited, its outer electrons can have different transitions, but these transitions should follow certain rules (i.e., "spectral selection rules"). Therefore, a series of characteristic spectral lines of different wavelengths can be generated for the atoms of a specific element. These spectral lines are arranged in a certain order and maintain a certain intensity ratio. Among them, specifically, a visible light spectrometer is used to measure the 380 - 760 nm band, a near-infrared spectrometer is used to measure the 760 nm - 2.5 m band, and an infrared spectrometer is used to measure the 2.5 - 3 m band. The data obtained by the determination module 8 is used to perform band analysis on the beam.

[0048] Furthermore, the control module 9 includes:

[0049] STM32F103 chip control sub-module, CMOS component, A / D converter, and instruction generation sub-module;

[0050] The STM32F103 chip control sub-module is used to input the input light type corresponding to the current input light into the selection module 10 and determine whether the input light type corresponding to the current input light conforms to the current light window. If not, the CMOS component is used to convert the beam band information set into a voltage that varies linearly with temperature, and the A / D converter converts the voltage that varies linearly with temperature within a preset voltage range into a digital image signal. The instruction generation sub-module is used to generate a corresponding conversion instruction according to the digital image signal.

[0051] Specifically, the control module 9 uses the STM32F103 chip control system to perform data analysis on the obtained data. Among them, the sensor uses a CMOS component, and through the photoelectric effect and an A / D converter, a voltage that varies linearly with temperature is obtained. The conversion range is between 2V < VDDA (analog positive power supply) < 3.6V. The control chip is used to convert the electrical signal output by the sensor into a numerical value.

[0052] Furthermore, the selection module 10 includes:

[0053] Infrared photon module and visible photon module;

[0054] The infrared photon module is used to select the diamond light window 5 according to the input light type, and the visible photon module is used to select the sapphire light window 6 according to the input light type.

[0055] Specifically, the selection module 10 includes an infrared photon module and a visible photon module, which are switched according to instructions issued by the control module 9. The control chip is an STM32F103 chip, which has two 12-bit ADCs (Analog-to-Digital Converters) embedded, and each ADC has 16 external channels. VDD is used to provide the required voltage for STM32F103, VDDA is the operating voltage of the analog devices inside the chip, VSSA is the common terminal of the analog devices, and VBAT supplies power to the back area to ensure that the control module 9 provides power for normal operation. Specifically, the reset circuit uses the charging and discharging principle of the RC circuit to give a short low level to the reset pin (NRST) of the microcontroller at the moment the chip is powered on, so that the microcontroller program is reset and all register states except the backup area register are restored to their original states. When the power is just turned on, the current will pass through R19 and C20 to the ground to charge C20. At this time, the NRST pin is at a low level. When C20 is fully charged, C20 is in an "off" state, and NRST changes from a low level to a high level. The burning port is used to burn the program into the microcontroller. It uses the SWD interface to burn, takes up little space, and only requires five wires. Use Boot0 and Boot1 to select the startup mode of the STM32 microcontroller. When Boot1 is X and Boot1 is 0, the main flash memory is started. When Boot0 is 0 and Boot1 is 1, the system memory is started. When Boot0 is 1 and Boot1 is 1, the built-in SRAM is started. That is, Boot1 and Boot0 are all grounded, and it can work normally. The motor can be rotated by the program of the microcontroller in the burning port, and different light window systems can be selected.

[0056] Furthermore, the diamond light window 5 and the sapphire light window 6 are both circular.

[0057] Furthermore, the surface roughness of the diamond light window 5 is in the range of 0 to 2 nm, and the thickness of the diamond light window 5 is 50 um.

[0058] Furthermore, the surface roughness of the sapphire light window 6 is in the range of 0 to 0.01 um, and the thickness of the sapphire light window 6 is in the range of 0.4 mm to 0.7 mm.

[0059] Specifically, the diamond light window 5 adopts a diamond disc with a surface roughness of less than or equal to 2nm, a thickness of 50um, and a diameter of 5 to 15mm, and is connected to the plate holder 1 through vacuum brazing technology. The sapphire light window 6 adopts a sapphire disc with a surface roughness of less than or equal to 0.01um, a thickness of 0.4mm to 0.7mm, and a diameter of 5 to 15mm, and is connected to the plate holder 1 through vacuum brazing technology. Vacuum brazing technology is used to braze the diamond light window 5 and the sapphire light window 6. Specifically, the vacuum degree is 5Pa, the joint pressure during welding is 0.05MPa, the heating rate is 10℃ / min, and the cooling rate is 5℃ / min. Glass powder is used for brazing, and the vacuum brazed support is connected to the converter 3. A limiter is provided on the converter 3 to limit the rotation angle of the converter 3 to 180°. The converter 3 is connected to the support structure 4, and the support structure 4 provides support for the entire intelligent light window system to avoid misalignment during use.

[0060] Further, such as Figure 3-7 As shown, the diamond light window 5 and the sapphire light window 6 are connected by vacuum brazing technology to form the diamond and sapphire light windows 2.

[0061] Since vacuum brazing has high-quality joints, the joint gaps produced by vacuum brazing are extremely small, and the bonding between the joint materials is firm and reliable. Unlike traditional brazing methods, vacuum brazing does not require the use of flux. The flux may contaminate the joint and needs to be cleaned after brazing. Vacuum brazing does not require the use of flux, so the joint is cleaner. Vacuum brazing is carried out in a vacuum environment, which can reduce the oxidation and scaling of the jointed metal. This avoids the metal oxide on the joint reducing the efficiency of the light window system. It is embedded with the film support 1, which is a circular double-circular hole structure. The circular double-circular hole shape can make more efficient use of space and save material costs. A converter 3 is provided at the bottom of the film support 1, which is driven by a motor. The rotational motion of the motor is transmitted to the film support 1 through the transmission system, thereby realizing the rotation of the film support 1. At the same time, the device is equipped with a limit switch to control the rotation angle of the film support 1. The limit switch uses the output signal triggered by the photoelectric sensor to detect the entry or exit of the rotating device to control the rotation angle of the rotating device, so that the angle of the film support 1 can always only rotate 180°.

[0062] The rotating device is driven by a motor, and the rotational motion of the motor is transmitted to the film support 1 through a transmission system, thereby realizing the rotation of the film support 1. At the same time, the device is equipped with a limit switch for controlling the rotation angle of the film support 1. The light window conversion mode is set so that the rotating device rotates 180° clockwise. In order to avoid misalignment during the rotation process, the rotating machine is installed above the supporting structure 4. The supporting structure 4 provides support for the entire intelligent light window system to ensure its normal use and prevent misalignment when the light window is rotated.

[0063] Furthermore, the switching module 11 includes:

[0064] The sheet support 1, the converter 3 and the support structure 4 are connected in sequence;

[0065] The film holder 1 is connected to the sapphire light window 6;

[0066] The supporting structure 4 is used to provide support for the film support 1 and the converter 3. The converter 3 is used to drive the film support 1 to rotate. The film support 1 is used to realize the switching of the current light window. A limit switch is provided on the switch, and the switch is used to limit the rotation angle of the switch.

[0067] Specifically, the determination module 8 obtains the wavelength band information of the light beam, determines whether the wavelength band of the light beam is infrared light or visible light, and transmits the wavelength band information of the light beam to the control module 9. The chip control system selects the corresponding light window material through the selection module 10, and the diamond light window 5 is used in the infrared light band, and the sapphire light window 6 is used in the visible light band. The two are selected and converted by rotation. A converter 3 is provided at the bottom of the film support 1, which is driven by a motor and transmits the rotational motion of the motor to the film support 1 through a transmission system, thereby realizing the rotation of the film support 1. At the same time, the device is equipped with a limit switch for controlling the rotation angle of the film support 1. The limit switch uses the output signal triggered by the photoelectric sensor to detect the entry or exit of the rotating device to control the rotation angle of the rotating device, so that the angle of the film support 1 can always only rotate 180°.

[0068] Furthermore, the software delay function of the microcontroller is used to control the duration of the high and low levels in each PWM signal cycle to achieve the required duty cycle of the PWM signal. The following program is used to control the speed of the light window, and the operator can adjust the speed as needed.

[0069] #include<reg51.h>

[0070] delayms(unsigned intx)

[0071] {

[0072] unsigned int I,j;

[0073] for(i=x;i>0;i--)

[0074] for(j=125;j>0;j--);

[0075] sbit ENA = P1^7;

[0076] main()

[0077] {

[0078] ENA=1;

[0079] while(1)

[0080] {

[0081] P2 = 0x01; / / Motor rotates 180°

[0082] P2 = 0x00; / / motor stops

[0083] delayms(40);

[0084] }

[0085] }

[0086] The specific process is: Initialization settings:

[0087] Define pin P1^7 as enable signal ENA; define delay function delayms, which implements millisecond-level delay through nested loops.

[0088] Main program starts:

[0089] The enable signal ENA on the microcontroller is set to a high level (value is 1), indicating that the motor drive mechanism has been enabled.

[0090] Enter the main loop (do the following indefinitely):

[0091] Set the value of P2 to 0x01: control the motor to rotate 180°.

[0092] Then set the value of P2 to 0x00: stop the motor.

[0093] Call delayms(40) to delay for about 40 milliseconds to give the motor some time to pause.

[0094] The process continues in a loop:

[0095] The operations from the previous step will be executed in a loop, and the motor will continue to run in a 180° rotation and stop mode.

[0096] This program is a simple MCU motor control logic, which uses the I / O control pins and delay function of the 51 MCU to repeatedly switch the motor's running state and stationary state. At the same time, there is a delay interval between each cycle.

[0097] The delayms() in the program is a user-defined software delay function, which is called when the motor is running forward or stopped to control whether the motor is running. When the sum of the actual parameters of the motor running and stopping remains unchanged, proportionally increasing the actual parameters of the motor running forward can control the motor speed to increase proportionally. Conversely, proportionally reducing the actual parameters of the motor running forward can control the motor speed to decrease proportionally, so that the speed control of the DC motor can be achieved. It is convenient for the operator to control the rotation time of the light window.

[0098] The timer interrupt of the microcontroller and the number of interrupts are used to control the duration of the high and low levels in one PWM signal cycle to achieve the required duty cycle of the PWM signal.

[0114] {Motor1 = 1; Motor2 = 0:}

[0115] else / / Motor stop time

[0116] {Motor1 = 0; Motor2 = 0;}

[0117] }

[0118] The specific process above is:

[0119] Initialization settings:

[0120] Define the motor control pins:

[0121] Motor1 (connected to P2^0) is used to control the motor to rotate forward.

[0122] Motor2 (connected to P2^1) is used to control the motor to reverse or stop.

[0123] Define the enable signal ENA (connected to P1^7) to enable the motor driver module. Define the global variable time to count the number of timer interrupts.

[0124] Main function logic:

[0125] Set ENA=1 to enable the motor driver module.

[0126] Configure timer A:

[0127] Set TMOD = 0x10, that is, timer A works in mode 1 (16-bit timing mode). Set the initial timing value to (65536-100) to achieve 0.1ms timing:

[0128] High byte TH1 = (65536-100) / 256.

[0129] Low byte TL1 = (65536-100)%256.

[0130] Enable interrupts:

[0131] Enable the general interrupt EA=1.

[0132] Turn on timer A interrupt ET1=1.

[0133] Start timer A: TR1=1.

[0134] The main loop while(1){} is empty, and the program logic completely relies on interrupt processing.

[0135] Timer A interrupt service function:

[0136] Each time a timer interrupt occurs:

[0137] Turn off timer: TR1=0.

[0138] Reinstall the timer initial value (to ensure that the timer continues to run at a period of 0.1ms):

[0139] High byte TH1 = (65536-100) / 256.

[0140] Low byte TL1 = (65536-100)%256.

[0141] Start timer: TR1=1.

[0142] Increase the interrupt count variable: time++.

[0143] Determine time:

[0144] If time>=10, it means the 1ms cycle is completed and time=0 is reset.

[0145] If time<=2, the motor is controlled to rotate forward:

[0146] Motor1=1: Forward signal high level.

[0147] Motor2=0: Reverse signal low level.

[0148] If time>2, the motor is controlled to stop:

[0149] Motor1=0: Forward signal low level.

[0150] Motor2=0: Reverse signal low level.

[0151] Program operation logic:

[0152] The program triggers the interrupt service function every 0.1ms through the timer A interrupt.

[0153] The interrupt service function controls the forward rotation and stop of the motor according to the value of time:

[0154] In each 1ms cycle:

[0155] The motor rotates forward during the first 0.2ms (time <= 2).

[0156] After 0.8ms (time>2), the motor stops.

[0157] The main loop is empty, the program logic is completely dependent on interrupt drive, and the motor runs in a fixed forward-stop mode.

[0158] The program only uses Timer A among the two internal timers of the 51 single-chip microcomputer (A is one of the two timers). The time for Timer A to time once is 100 μs. Each time the timing time arrives, the interrupt count flag time is incremented in the interrupt program. And according to the value of the interrupt count flag time, the period and duty cycle of the PWM signal are determined. The time value in the first if statement determines the period, the time value in the second if statement determines the forward rotation time of the motor, and the time value corresponding to the else statement determines the stop time of the motor. In this example, the set period of the PWM signal is 1 ms, the forward rotation time of the motor is 200 μs, and the stop time of the motor is 800 μs. When the period of the PWM signal remains unchanged, proportionally increasing the forward rotation time of the motor can control the speed of the motor to increase proportionally. Conversely, proportionally decreasing the forward rotation time of the motor can control the speed of the motor to decrease proportionally. In this way, the speed control of the DC motor can be achieved, which is convenient for the operator to adjust the rotation speed of the optical window according to the requirements.

[0159] Specifically, set the optical window conversion method. Use the chip to set the conversion method of the diamond optical window 5 and the sapphire optical window 6 to rotate 180°. Use the STM32F103 chip control system to analyze the obtained data. Through the photoelectric effect and the A / D converter, a voltage that linearly changes with temperature is obtained, and the conversion range is between 2V < VDDA (analog positive power supply) < 3.6V. Use the control chip to convert the electrical signal output by the sensor into a numerical value. Among them, the sensor uses a CMOS component. Through the pixel array on the CMOS, the photodiode has the characteristics of forward conduction and reverse cut-off. Its reverse characteristic also has a capacitance characteristic. When a reverse bias voltage is applied to the diode, the capacitor will be charged. When the capacitor is full of charge, the incidence of photons will cause new electron-hole pairs to be excited in the internal structure, and pair and discharge with the electron-hole pairs formed by the original charging to form a photocurrent. The photocurrent charges the capacitor on the right side to become a voltage output. The sensed optical signal is converted into an electrical signal, and through the readout circuit, the optical signal is converted into a digital signal, thereby realizing the digitization of the actual scene.
