What is the simple working principle of the camera?
The basic principle of the camera was to convert optical image signals into electrical signals for storage or transmission. When shooting an object, the light reflected from the object is collected by the camera lens and focused on the light receiving surface of the camera device. The light is converted into electrical energy by the camera device to obtain a "video signal". Because the optical signal was very weak, it needed to be amplified by the pre-amplifier circuit, and then processed and adjusted by various circuits. The final standard signal could be sent to a recording medium such as a video recorder, or transmitted through a transmission system or sent to a monitor for display. In addition, the working principle of some modern cameras involved more links. For example, the Sensor image sensor in the camera first sensed the external light and converted it into an image, then transmitted the data to the SoC (System on a Chip) for unified pre-processing, such as drying, enhancing contrast, adjusting color, etc. Then it was transferred to the AI module, using pre-trained algorithms to analyze the image and classify the output results. There were also some special-purpose cameras. For example, the intelligent drip recognition camera in the factory determined whether a liquid drip event occurred through a predetermined drip detection algorithm and pattern recognition technology. The automatic water level monitoring camera continuously captured water surface images and used image processing algorithms to extract water level information. Read more exciting novels for free
The working principle of oil extraction
The working principle of oil extraction included geological exploration, drilling, oil extraction, and transportation. The location and nature of the oil reservoir can be determined through geological survey and geological survey. Well drilling was the process of passing a drill bit through the earth and into the oil reservoir. Oil extraction was the process of extracting oil from a reservoir. Transportation was the process of transporting the extracted oil to its destination. The specific mining methods included natural pressure mining, artificial pumping, water flooding, and gas flooding.
The working principle of 2D and 3D
The working principles of the 2D and 3D are different. You can refer to the following explanation: Two-dimensional refers to the fictional two-dimensional world that usually appears in anime, comics, games, and other media. In the 2D world, characters, scenes, and things were flat, and the colors and shapes were simple geometric shapes. The working principle of 2D was based on the projection principle by projecting an image onto a two-dimensional plane to create a virtual world. The three-dimensional world refers to the real world we live in. In the three-dimensional world, characters, scenes, and things were all three-dimensional, and the colors and shapes were all complicated. The working principle of the three-dimensional world was based on the principle of perspective. By observing an object from different angles and distances, one could obtain its shape, size, position, and other characteristics. Therefore, the difference between the working principle of 2D and 3D was that they were based on different principles and presentation methods.
The working principle of the cvl transmission
The CVS transmission was mainly composed of two variable diameter rollers (shaped like a pair of cones) and a steel belt or chain. One of the rollers was connected to the engine (power input) and the other was connected to the drive shaft (power output). During operation, the transmission ratio was changed by changing the diameter of the rollers (that is, the contact diameter between the cone and the steel belt or chain). For example, when driving at a low speed, the diameter of the input end of the wheel was smaller and the speed was higher, while the diameter of the output end of the wheel was larger and the speed was lower. As the speed of the car increased, the diameter of the two wheels changed, causing the speed of the output end of the wheel to increase. According to the different power transmitting devices, it could be divided into steel belt CVs and chain CVs. When the steel-belt CVS works, the driving cone wheel presses the side of the steel belt formed by the overlapping of the metal sheets and the metal rings to form static friction force, and the hardness between the push sheet materials is used to form thrust force, so that the steel belt drives the driven cone wheel to rotate to transmit power. When the driving wheel is clamped to the middle by the oil pressure device, the steel belt moves upward along the side wall, the circumference of the driving wheel increases, and the circumference of the driven wheel decreases, thus realizing the amplification of the engine's torque-force. The chain of the chain-type CVS was composed of a ring-shaped steel sheet and a pull piece. When it worked, the chain did not directly contact the cone wheel, but the middle rocking arm pin was pressed to achieve the transmission of the moment.

The working principle of Bluetooth is easy to understand
Bluetooth works by connecting devices through radio waves, allowing them to communicate over short distances. The Bluetooth device includes a Bluetooth module, a Bluetooth radio, and software. When two Bluetooth devices wanted to communicate with each other, they needed to pair up. Communication between Bluetooth devices was carried out in a short-range temporary network that could accommodate two to eight devices. After the network environment was successfully created, one device would be the master device, and the other devices would be the slave devices. Different types of Bluetooth technology had different versions of the core specifications. Bluetooth uses the 2.4-gigasecond radio frequency band for communication, which is divided into multiple small channels to avoid interference. Bluetooth's global usefulness and low power requirements made it a popular standard for connecting all kinds of devices, from consumer electronics to business applications to Internet of Things devices.
Deep-Sea Submersible Working Principle
Different types of deep-sea submarines worked differently. For some simple diving simulation devices, such as a device that put a small glass bottle half filled with water into a big bottle, when the bottle was squeezed by hand, the water would enter the small bottle mouth and squeeze the air in the bottle, making the drainage volume smaller. When the gravity was greater than the buoyancy, the water would fall. When the bottle was released, the air volume would expand, and the buoyancy would rise when the gravity was greater than the gravity. The Dragon and other deep-sea manned submarines had ballasting iron. In the early stage, they were negative in buoyancy. After entering the sea, they began to sink. After all the work was completed, the submariners threw away the ballasting iron, became positive in buoyancy, and began to rise. This was because the deep-sea submarine was deep and the environmental pressure was high. The compressed air was not enough to force out the seawater in the air cabin, so the method of abandoning the ballasts was used to float up. Generally, the electromagnetic control was used to control the ballasting iron. If the deep-sea submarine lost power and the electromagnetic was ineffective, the ballasting iron would automatically separate from the submarine under the effect of gravity and make the submarine float. In terms of safety, Dragon's design not only included throwing away the ballasting iron, but also heavy objects such as the battery box and the sample basket. If it was entangled by seaweed, it could also abandon the robotic arm, and the alarm system could also send a float to the surface to seek rescue from the mother ship. In addition, the Endeavor used a cable-less and unpowered floating and diving technology. Generally speaking, the diving method of a deep-sea submarine was the same as that of a submarine. They both injected seawater into the air cabin, but the method of surfacing was different. Moreover, the deep-sea submarine was not completely autonomous. It had to rely on the mother ship to replenish energy and air. The novel " Flood Dragon " is equally exciting. Everyone is welcome to click and read it!
A simple explanation of the flight principle of an airplane
Airplane flight was mainly based on the following principles: 1. ** Creating lift ** - For an ordinary airplane, the shape of the wings was designed to cause the air to flow at different speeds across the upper and lower surfaces of the wings. According to the Bernoullian principle, the greater the flow rate of the fluid, the lower the pressure. The upper surface of the wing was usually curved, so the air flow was fast and the pressure was small. The lower surface was flat, so the air flow was slow and the pressure was strong, thus creating an upward pressure difference, which was the lift force. In addition, the lift was also related to factors such as the angle of attack (the angle between the wing chord and the relative airflow speed). - For helicopters, the large propellers stirred the air to generate lift when they rotated. When the lift was greater than the helicopter's own weight, the helicopter could take off, and the height could be adjusted by changing the speed of the propeller in flight. 2. ** Obtained Thrust Force ** - The aircraft could obtain forward thrust through the engine. A common type of engine, such as a piston-type engine (such as the early star engine), produced forward traction by driving the propeller to rotate. The turbine jet engine was a high-speed air compression engine. The air was compressed by the high-speed operation of the air intake. The combustion chamber sprayed oil and burned it. The gas rushed back to the turbine, which drove the air compression engine. The gas flow was ejected from the spout to generate thrust. Turbofan engines (turbine-fan engines) had two internal and external bypass passages. The ratio of the air flow rate of the external bypass passage to the internal bypass passage was the bypass ratio. The larger the bypass ratio, the more fuel efficient it was. It was widely used in aircraft flying at subsonic speeds such as passenger planes. Its main thrust could come from the air ejected backward at high speed from the external bypass passage. The turbine prop-jet engine was similar to the turbine jet engine, which was connected to a decelerator and drove an external propeller. It was mostly used in small or low-speed subsonic aircraft, but there were exceptions. There was also a propfan engine. There was no decelerator, and the propeller had a high speed. The fuel efficiency was further improved, but it was noisy. Turboshaft engines transmit power through a shaft and are used in helicopters. 3. ** Controlling the flying posture ** - The aircraft had three axes of motion: pitch, roll, and yawing. The roll was controlled by the ailerons, the pitch was controlled by the elevators, and the yawing was controlled by the rudders. - If the helicopter only had the main propeller rotating, the body would rotate according to the conservation of momentum. Therefore, the small propeller on the side of the tail of the helicopter was used to prevent the body from rotating, so that the helicopter could turn left, turn right, or maintain a stable course. 4. ** Maintain center of gravity and balance **: The position of the aircraft's center of gravity needs to be reasonably distributed to ensure balance and stability during flight. Different types of aircraft structures and arrangements were designed with the center of gravity and balance in mind. The novel "Hundred Years of Spaceship" is equally exciting.

Working Principle of Rain Interception Hanging Basket
The working principle of the rainwater intercepting hanging basket device was to use gravity to separate the dirt in the rainwater and settle it at the bottom of the basket, while the clear water flowed out from the top of the basket. The device collected rainwater and sewage through a basket-like object, while preventing sewage from entering the rainwater pipe, reducing environmental pollution. This device usually consisted of a basket and a support frame. The basket was usually made of plastic or stainless steel, and its shape and size were designed according to actual needs. When using this device, the bottom of the basket needed to be cleaned regularly to prevent blockage and odor. At the same time, the integrity and cleanliness of the device needed to be checked regularly to ensure that it was functioning properly.
