Find the item "restore on AC / power loss" in the power window, press enter, and then set its value to "power on" through the direction key;Step 2: select "resume onrtc alarm" and press enter, and then set its value to "enable" through the direction key; Step 3: select RTC"Alarmdate" press enter, and then set its value to "every day", indicating that the same operation is performed every day. According to the same method, respectively "RTC alarm""Second" is set to "07", "55" and "00", which means that the startup time is "7:55:00" in the morning. After all settings are set, press F10 to save and restart.Because the BIOS of different motherboards is different, the settings of some motherboards may be a little different from those above, but just remember to find "wake up" or "resume by" in power managementThe word "alarm" is OK, because this is the option to set the timed startup.2 With the help of shortcuts, the display information file is automatically run after startupStep 1: associate the display file with the display program. For example, the display file is "common. Led", and the program to open it is "led. Exe". Just click "common. L e" with the right mouse buttonD "icon, click" attribute ", click" change "button in the" general "option, find the program" led.exe ", and click" OK ";Step 2: generate a shortcut to the display file. Right click the "common. Led" icon and click "create shortcut" to display a "shortcut to"Click "common. Led" icon, then click "start", "run" and "Browse" in the lower left corner of the computer display screen, find the "shortcut to common. Led" file and confirm it, and copy the ""... Shortcut in the "open" columnTo the common. Led. LNK ''. Note: if you click "OK", you can directly open the display file "common. Led";Step 3: set the startup item in the super rabbit. Download the super rabbit software on the Internet and install it into the LED display server computer. Open the "magic settings - create your own system" in the "rabbit tool", right-click in the "startup program", select "new project", and paste it in the "command line"D: Led shortcut to "common. Led. LNK", the title is set by yourself.After this setting, the startup will automatically run the display file "common. Led", which has the same effect as manually opening "common. Led".Technology 2: how to detect the quality of LED display pixels from the unit board"Pixel" is a unit used to calculate digital images. Like photographic photos, digital images also have continuous shades. If we enlarge the image several times, we will find that these continuous tones are actually composed of many small square points with similar colors. These small square points are the smallest unit "pixel" of the image. This smallest graphic unit can be displayed on the screen, usually a single dye point.According to the color principle, we know that red (R), green (g) and blue (b) are called three primary colors. These three colors can be combined to obtain any color from black to white. In the classification of LED display screen, there are monochrome display screen, two-color display screen and full-color display screen. Monochrome is relatively simple. You only need to select any one of the three primary colors to realize monochrome display. In practical application, there are many red LED lamps. In this way, a red LED is a pixel.The two-color display screen is similar to the monochrome display screen. As long as any two of the three primary colors are selected, the two-color display can be realized. In practical application, red and green are often selected. When red and green are on at the same time, yellow can be realized. Therefore, the two-color display can realize three colors: red, green and yellow.
Process Analysis of LED Video Processor Processing the Display Effect of LED Display Screen
Process Analysis of LED Video Processor Processing the Display Effect of LED Display Screen
Video processor is the witness and landmark equipment for the birth, growth and maturity of full-color LED display. Today, led special video processing equipment is also gradually maturing in this process. The quality of LED video processor directly affects the display effect of LED display.In general, LED video processor is a special video processor for LED. The task it needs to complete, in short, is to convert the image signal from the outside (such as Blu ray DVD, computer, HD playback box, etc.) into the signal acceptable to the LED display screen. In this process, the LED video processor generally needs to complete the following processing processes:1 Resolution specification conversion: Generally speaking, the signal resolution provided by image signal sources (such as Blu ray DVD, computer, HD playback box, etc.) has fixed specifications (refer to VESA, ITU, SMPTE and other standards), while the modular splicing display of LED display makes its resolution almost arbitrary. The video processor converts various signal resolutions into the actual physical display resolution of LED display screen.2 Color space conversion: the color gamut of LED display is very wide, while the color space of most image signals is relatively small (such as NTSC). In order to make the LED display have excellent image display effect, color space conversion must be carried out.3 Bit depth improvement: at present, the gray level of LED display has been increased to 16 bits and 17 bits, but most of the input signal sources are only 8 bits. Therefore, following the arrival of the era of high-definition display, the application of 10 bit or even 12 bit processing technology in video processor has become a general trend.4 Zoom: in the process of resolution specification conversion, the image needs to be scaled. Whether the resolution is increased or decreased, the complete image can be displayed on the screen.

Corning Brings Gorilla NBT Glass to Touch Screen Laptop
Corning Brings Gorilla NBT Glass to Touch Screen Laptop
key word:Corning, touch screen, notebookThe new protective glass helps to prevent damage to the touch screen; Corning gorilla glass enters new marketsCorning gorilla glass NBT, the latest protective glass launched by Corning today, aims to protect the touch screen laptop display from scratches and other damages caused by daily use.Gorilla NBT glass is a unique screen protection solution launched by Corning for touch screen laptops. Touch has become the main way of interaction between users and devices, and with the increase of touch interaction, the potential risk of glass scratch is also increasing. When these equipment are in intensive use every day, scratches will lead to the breakage of protective glass. Corning gorilla NBT glass has stronger scratch resistance. In case of scratch, the scratch visibility is smaller and the residual strength is higher, which can prevent the damage of notebook computer display when using sodium calcium glass with poor performance.Consumers pursue thinner, smoother and lighter personal computers with touch function. The market research conducted by market research institutions on the next wave of touch technology shows that in the next few years, in terms of protecting the glass market, laptops with touch function may reach the market share of smart phones. Corning gorilla NBT glass brings the world's leading protective glass solution with low cost, scratch and damage resistance expected by consumers to this new mobile device market."As the preferred protective glass for global equipment manufacturers, Corning gorilla glass has now entered the emerging touch screen notebook computer market with its special performance," said James R. Steiner, senior vice president and general manager of Corning special materials department. "As the demand for touch screen laptops continues to grow, we believe Corning gorilla NBT glass can challenge the current performance of soda lime glass, and its scratch resistance is 8-10 times that of soda lime glass. In fact, customers can now get the best protection glass solution at only 1% to 2% of the retail price of a laptop, which comes from gorilla Solution. In short, we believe that if you don't use gorilla glass on your device, it's not good enough. "Similar to handheld devices or tablet devices, consumers' physical contact with touch screen laptops includes tapping, tapping, grasping and cleaning. These interactions with laptop devices every day may cause scratches on the protective glass and affect the user experience. Corning consumer survey shows that the complaint rate of scratched laptop screens is more than four times higher than that of other mobile devices. Changing the screen can be very expensive, sometimes as much as half the price of the entire laptop, and users have to wait a few days."As a leader in touch computers, Dell is always looking for the best materials to ensure that our laptop screens can resist collision and scratch," said Sam Burd, vice president of Dell PC products group. "We used Corning gorilla NBT glass in the new client device to be launched this fall, which further strengthened the reliability and durability of our products to maintain the leading position in the industry."Corning gorilla NBT glass is now available and is expected to be applied to several notebook products of several world leading computer brands later this year.For more information about Corning gorilla NBT glass, please visit.

What Is Inside the Manipulator? Analysis of Structural Types of Parts
What Is Inside the Manipulator? Analysis of Structural Types of Parts
Manipulator modelWhen it comes to robots, what everyone should think of should be what is shown in the picture above.So, what's the inside of the manipulator and what's the secret? Let's share the main structure of pneumatic manipulator.1 Structure of each part of manipulatorStructure of each part of manipulator1. Swing cylinder 2. Positioning bolt 3. Pneumatic claw 4, 6, 9. Magnetic switch 5. Standard cylinder 7. Throttle valve 8. Duplex cylinder 10. Proximity switch 11. Buffer valve 12. SupportThe manipulator is composed of multiple links and joints. The manipulator is generally composed of base, actuator, such as clamp, suction cup, etc., as well as the joints and connecting rods between them. The manipulator can realize arbitrary movement and steering within its range of motion. We generally call the movable joints as degrees of freedom.Types of gas circuit componentsThe air circuit components involved in the pneumatic manipulator mainly include swing cylinder, duplex cylinder, pen cylinder and air source processing components.Air source treatment assemblyAir source treatment assemblyThe air source processing assembly is composed of a pressure regulating filter, an air inlet switch and an elbow. The air source is provided by the air compressor, the pressure range is 0.6 1.0MPa, and the output pressure is 0 0.8MPa, which can be adjusted. The output compressed air is sent to each working unit.Pen cylinderPen cylinderThe material is sent to the corresponding position through the reciprocating motion of the cylinder. If the direction of inlet and outlet air changes, the direction of movement of the cylinder will also change. Magnetic switches on both sides of the cylinder are mainly used to track whether the cylinder has moved to the specified position.Double coil solenoid valveDouble coil solenoid valveThe double coil solenoid valve mainly controls the air inlet and outlet of the cylinder to realize the telescopic movement of the cylinder. Pay attention to the positive and negative poles of the red indicator. If the positive and negative poles are connected reversely, it can also work, but the indicator is off.Single coil solenoid valveSingle coil solenoid valveThe single coil solenoid valve controls the single direction movement of the cylinder to realize the telescopic movement. The difference from the double coil solenoid valve is that the initial position of the double coil solenoid valve is not fixed and can arbitrarily control two positions, while the initial position of the single coil solenoid valve is fixed and can only control one direction.Action analysis of pneumatic componentsSchematic diagram of gripper controlThe manipulator detects its own state, such as speed, position and acceleration, through the internal sensor of the sensor, so as to realize the interaction between itself and environmental information, such as distance, temperature and pressure. The environmental information is detected by external sensors. Next, the controller selects the corresponding environment mode to command the manipulator to complete the task.The sensors used inside the manipulator mainly include the following:1. Photoelectric sensorPhotoelectric sensorPrinciple: diffuse emission occurs after the detection light emitted by the transmitter irradiates the measured object. After the receiver receives strong enough reflected light, the photoelectric switch starts to act.2. Inductive proximity switchInductive proximity switchPrinciple: there is an oscillator in the inductive proximity switch, which can generate alternating magnetic field. When the induction distance reaches a certain range, eddy current will be generated in the metal target, so as to weaken the oscillation intensity. The changes of oscillator oscillation and stop vibration are processed by the later amplification circuit and finally converted into switching signal.3. Cylinder piston in place detection - magnetic switchMagnetic switchPrinciple: after the cylinder piston with magnetic ring moves to the specified position, the two metal sheets in the magnetic switch are closed under the action of magnetic field, and the trigger signal is generated.4 Working principle of Pneumatic Manipulatorworking principlePneumatic manipulator is mainly composed of control system, driving system, actuator and position detection system. Under the control of PLC program, the action of actuator is realized through pneumatic transmission.The information of the control system transmits the command to the actuator to track the action of the manipulator. If there is an error or fault in the action, it will give an alarm immediately.The actual position of the actuator is transmitted to the control system by the position detection device, and finally the actuator is moved to the specified position with a certain accuracy.
The Design of a Small Planar Transformer / Inductor Is Introduced in Detail
The Design of a Small Planar Transformer / Inductor Is Introduced in Detail
1. IntroductionWith the rapid development of electronic information technology, various electronic devices have entered the SMT (surface mounting technology) era, and electronic devices are increasingly required to be light, thin and miniaturized. Although the traditional power electronic transformers and inductors have played an important role in the era of electronic tubes and discrete transistors, they can not be used in today's modular electronic equipment because of their large volume. How to develop small planar electronic transformers and inductors is the focus of designers. This paper describes the design and manufacture of 230khz, 120W small planar transformer and 20a, 10 with multilayer printed board manufacturing technology, NC machine tool processing technology, surface coating technology and high frequency and low loss ferrite core H high current filter inductor.2. Circuit form and technical indexes of transformer and inductorFigure 1 shows the main circuit of active clamp / reset single ended forward converter. The circuit has zero voltage conversion function, which is conducive to improve efficiency and reduce EMI / RFI.The circuit consists of vq2, VD2 and CCL, which provides a low resistance working path for the energy storage transfer of leakage inductance L1 and excitation inductance LM. After vq2 is turned on, CCL continues to be charged, and the current of the clamping circuit decreases in a resonant manner. Since the rectifier VD1 is cut off, L1 and LM are connected in series, and the resonant frequency is determined by L1, LM and Cl, there are certain inductance requirements for the primary of the transformer.In addition, after the circuit VQ1 is cut off, the voltage polarity of the transformer winding is reversed and Ca is charged. During the charging process, the magnetization current gradually decreases. By properly selecting parameters, vq2 is turned on before the zero crossing of the magnetization current, which makes it possible to change the direction of the magnetization current. The magnetization current is reversed and the clamping voltage UCL is reversed to the primary winding of the transformer, The working area of the drive transformer B-H extends to the second quadrant and the third quadrant. At the same time, the discharge of CCL capacitor energy storage is transferred to L1 and LM storage. After VQ1 is turned on, the B-H working point starts from the third quadrant, and the normal working area is basically symmetrical with the origin of the B-H axis. In this symmetrical area, the unidirectional variation value of B-H is consistent with that of the traditional single ended forward converter. In order to maintain normal output regulation, the same volt second product is applied to the transformer, and the resulting core loss is consistent with that of the single ended forward converter. During actual operation, the maximum working magnetic flux density (BM) shall be selected. The transformer can work in - BM BM, so B = 2bm, as shown in Figure 2.T1 in the circuit is the transformer we need to design, with working frequency f = 230khz, input voltage Vin = 230V and primary inductance LM = 117 H 10%, maximum working ratio 0.45, output voltage Vo = 5V, output current IO = 20a, Lo is filter inductance, Lo = 10 H. The working environment temperature is - 45 50 , the temperature rise is 50 , the test voltage is 2KV, the height of transformer and inductor is 12mm, and the length and width are about 40mm.3. Plane transformer, inductor core and structure3.1 magnetic coreAt present, the magnetic materials used in power switching transformers include permalloy, amorphous alloy, ultramicrocrystalline alloy, ferrite and other materials. Ferrite material is selected to make magnetic core. In order to make full use of effective space, magnetic core with thicker core column and wider window width must be selected, which is conducive to reducing turns and current density. In view of the limitation of the overall height, necessary processing is also required.3.2 windingIn the traditional winding, the coil is wound on the skeleton, and the conductor is of circular section. In addition, when the conductor flows through the high-frequency alternating current, it is also limited by the penetration depth of the skin effect. The calculation formula isWhere is the penetration depth (mm), Is the angular frequency, = 2f(rad) Is the conductor permeability (H / M), Is the conductor conductivity (s / M).The relative permeability of copper is equal to 1, which is the vacuum permeability, thenSubstituting this into the above formula can be simplified toWhere f = 230khz, the available conductor diameter is 2 = 0.275mm. Therefore, under the condition of high current, the transformer winding adopts multi strand winding, which will greatly reduce the utilization rate of magnetic core window. We decide that the primary winding and auxiliary winding with low current are made of multilayer printed board and double panel respectively, and the secondary winding and filter inductance winding up to 20A are made of folded copper strip with rectangular section, so as to make the most effective use of window holes.4. Transformer design4.1 the core size is determined by the power transmission capacityThe power transmission capacity of a transformer depends on the product of the area of the magnetic core column and the area of the window hole, APWhere: Pt is the sum of the primary and secondary power of the transformer. When the efficiency of the transformer is high, twice the output power can be taken. KJ is the structure constant of the magnetic core, which is between 365 and 632, and we take 450. B is the incremental magnetic induction intensity. According to the circuit B = 2bm, BM is taken as 0.1t, then B = 0.2T. F is the operating frequency 230 kHz. Ku is the window utilization, between 0.3 and 0.4. KF is the waveform coefficient, 4 for rectangular wave and 4.44 for sine wave.Substitute the above data into the calculationAfter repeated comparison and calculation, we selected PQ40 magnetic core and ground it into the size we need. As shown in Figure 3, the AP value is only 0.69.4.2 winding(1) Primary turns calculationWhereUp1 is the minimum amplitude of transformer input voltage 230V, B is the incremental magnetic induction intensity 0.2T, Is the maximum working ratio of 0.45, and SC is the cross-sectional area of the magnetic core of 1.74mm2.Substitute the above data into the calculationW1 = 12.93 turns.(2) Secondary turns calculationWhere: up2 is the voltage amplitude of secondary winding,Uo is the output voltage 5V. U2 is the voltage drop of rectifier tube and line. If 1.7V is taken, up2 = 14.889v, W2 = 0.837 turns.After adjusting the number of turns to an integerW1 = 15 turnsW2 = 1 turn4.3 winding currentIgnoring the exciting current, the effective values of the primary and secondary currents are calculated according to the unidirectional pulse square wave,4.4 winding form and temperature riseSince the effective value of the primary winding current is 0.895a, we use 8 layers of printed boards, each layer has 7.5 turns, 4 layers are connected in parallel, and then 7.5 turns are connected in series to form 15 turns of primary winding, as shown in Figure 4.When the primary winding works at full load, the loss is 1.07w.The effective value of the secondary winding current is 13.42a. Considering the limitation of skin effect penetration rate, we use two copper strips with a thickness of 0.3mm, which are processed into the shape shown in Figure 5 by CNC machine tool. When the secondary winding works at full load, the loss is 0.709w. One turn of auxiliary winding and one turn of feedback winding are made of double-sided plate, and the shape is shown in Fig. 6. Since the current is very small, the loss is negligible.According to the data, the iron loss calculated from the working frequency, BM value and working temperature is 1.296w.The appearance of the transformer after assembly is shown in Figure 7, and its heat dissipation area is s = 42.88cm2. Dissipated power per unit area q = 0.0524w/cm2. According to Fig. 8, the temperature rise is 42 . The measured temperature rise at full load is 34 .5. Filter inductance designIn the design of filter inductor, we use pq32 magnetic core and grind it into the shape and size shown in Figure 9.5.1 determine the number of turns of filter inductance WWhere l is the inductance required by the technical index. The leakage inductance in the case of atmospheric gap accounts for 20%. The core inductance only needs to be 0.8L. LG is the air gap length. Considering that the inductance requires good linearity, LG is taken as 1.8mm. AG is the equivalent section at the air gap, Ag is 1.2 times the magnetic core section, Ag = 1.267mm2.Substitute the above data to obtainW = 9.52 turns, rounded to 10 turns.5.2 determination of winding form and temperature rise calculationConsidering that the inductance current reaches 20a, only the ripple frequency is 230khz, and the main component is still DC current, a copper strip with thickness of 0.45mm and width of 4.5mm is used as the winding.Processed by CNC machine tool, the folded shape is shown in FIG. 10 and expanded as shown in FIG. 11.After calculation, the winding section is s = 2.025mm2, the winding length is L = 0.612m, and the winding loss PM = 2.7992w.Since B is very low during operation, the iron loss is ignored.The outline of filter inductor after assembly is shown in Figure 12. According to the overall dimensions, the heat dissipation area is s = 27.04cm2, and the dissipated power per unit area is q = 0.10352w/cm2. According to Fig. 8, the temperature rise is 65 . The measured temperature rise at full load is 48 .6. Analysis that the temperature rise of transformer (filter inductor) assembled on aluminum substrate with radiator can be greatly reducedBecause the contact area between the mounting bracket and the base plate of the traditional transformer is less than 1% of the overall area, and no measures are taken, the base plate is not included in the scope of helping heat dissipation. The good contact area between the plane transformer and the base plate can reach about 25%, which greatly improves the heat dissipation conditions.Heat conduction refers to the study of the way and effect of energy transfer of each part of the object in direct contact.We will discuss the effect of transformer assembly on aluminum substrate with radiator. The following conditions must be known:The theoretical temperature rise of transformer is 42 .After the transformer works at full load for several hours, the actual temperature rise of the bottom surface in contact with the aluminum substrate is 29 . The surface temperature rise of the radiator in contact with the cold plate is 27 .According to the conversion of 1 kW · H = 859.8 kcal, the total loss of transformer is 2.051 w · H = 1.763 kcal.Heat Q derived from heat conduction engineering calculation under stable working condition of multi-layer flat wall:Where: t1-t5 is the temperature difference of multi-layer surface wall of 2 . Rr1... RR4 is the total thermal resistance of multilayer flat wall (· H / kcal). Is the thickness of flat wall of each layer (m). Thermal conductive adhesive 0.0001, copper foil 0.00015, medium 0.00015, aluminum substrate 0.002. Is the thermal conductivity of each layer of flat wall (kcal / (m · h ·). Thermal conductive adhesive 0.194, copper foil 330, medium 0.26, aluminum substrate 204. A is the contact area between the bottom of the transformer and the flat wall 0.00104m2.Substitute the above data to obtainQ=0.3873(kcal)That is, the aluminum substrate with radiator transfers 21.96% of the total loss of 2.051w of the transformer, so it is reasonable to reduce the actual temperature rise by about 20%.In the same way, the effect of aluminum substrate with radiator on filter inductance can be calculated, which will not be repeated here.7. ConclusionThe transformer and filter inductor designed above have passed the electrical performance test, high and low temperature cycle test and high and low temperature storage test, and their performance meets the requirements.Through the transformer and filter inductance designed in this scheme, the following conclusions can be drawn:The folded copper strip processed by NC machine tool not only meets the high frequency limited by the penetration rate of skin effect, but also has a rectangular section. In addition, the copper strip surface is insulated with paint, which greatly improves the utilization rate of window holes. Compared with manual winding, the winding of folded copper strip, multilayer printed board and double-sided board has good consistency of distribution parameters and is convenient for circuit debugging.For switching transformers and filter inductors with operating frequencies above 200kHz, they can be designed into small planarization, and their height can be reduced to the same order of magnitude as components such as integrated circuits and capacitors. They can also be assembled on aluminum substrates with radiators. With the help of radiators, the temperature rise can be reduced by more than 20% under the condition of the same dissipated power.In case of mass production, the magnetic core shall be redesigned as required to increase its bottom area and make the window more reasonable, and the temperature rise and size of transformer and filter inductor will be further reduced.
